Long-term Effects of Pre-operative Testosterone and Dihydrotestosterone on Glans Width in Boys With Hypospadias

BackgroundSmall glans width is a risk factor for urethroplasty complications. This study aimed to assess and compare short- and long-term effects of two pre-operative topical androgen treatment protocols on maximum glans width. Furthermore, to evaluate post-operative complications when surgery was delayed >3 months following hormonal treatment completion. MethodsTopical 2.5% dihydrotestosterone (February 2016–July 2018) and 5% testosterone (August 2018–December 2022) treatment protocols, completed >3 months before surgery, were offered to all children with proximal hypospadias and small glans width requiring urethroplasty. Serial glans width measurements were collected prospectively pre- and post-androgen treatment. Demographic data and complications were collected retrospectively. ResultsA significant increase in mean glans width was observed following both dihydrotestosterone (6.1 mm [95% CI 4.3–7.9 mm] pre-dihydrotestosterone to 14.9 mm [13.2–16.6 mm, p < 0.0001] post-dihydrotestosterone in 11 children) and testosterone (10.5 mm [9.9–11.1 mm] pre-testosterone to 14.6 mm [13.7–15.5 mm, p < 0.0001] post-testosterone in 32 children). Serial post-treatment measurements showed no loss of gained width >1 year after treatment completion. Mean increase in glans width from pre-treatment measurement at 0–3 months, 4–12 months and >12 months following treatment was 7 mm (95% CI 3.8–10.2), 9 mm (7.2–10.8) and 10 mm (7.3–12.7) post-dihydrotestosterone and 4.4 mm (95% CI 3.4–5.4 mm), 4.3 mm (3.5–5.2) and 5.1 mm (4–6.2) post-testosterone respectively. Complications were noted in 4/22 patients who received topical androgen prior to initial hypospadias surgery and had completed all surgical stages. ConclusionsBoth treatment protocols produced a significant, sustained increase in glans width. Delaying hypospadias surgery for >3 months following androgen application may circumvent androgen induced vascularity and poor wound healing. Level of EvidenceLevel IV. Type of StudyTreatment study.

Primary hypospadias repair outcomes: results from a retrospective cohort of 292 children.

Hypospadias surgery is challenging. Numerous techniques have been described with variable complication rates. The main objectives of our study were to evaluate the urethroplasty complication rate of primary hypospadias repair and to identify risk factors for complications. We retrospectively evaluated the outcomes of all patients who underwent primary hypospadias repair in our department between January 2012 and December 2020. Demographic, anatomical, operative, and postoperative data were reported. Univariate and multivariate logistic regression analyses were performed to identify variables associated with complications. Statistical significance was set at p < 0.05. Of 292 patients, 203 (69.5%) had distal hypospadias, 63 (21.6%) had mid-penile hypospadias, and 26 (8.9%) had proximal hypospadias. The mean age at the time of surgery was 22.8months. Seventy-eight patients (26.7%) had urethroplasty complications. The rate of complications was higher for proximal hypospadias (57.7%), onlay island flap (44.4%), and Koyanagi (75%) procedures. The mean follow-up duration was 29months. Two predictors of complications were identified by multivariate analysis: catheterization duration and urethroplasty technique. The reoperation rate was 30.5%. Urethroplasty complications frequently occur after primary hypospadias repair. The complication rate was higher in proximal hypospadias. Catheterization duration and surgical technique were significant predictors of complications. A longer and more standardized follow-up is needed for a better assessment of hypospadias repair outcomes.

Use of Validated Questionnaires to Predict Cosmetic Outcomes of Hypospadias Repair.

Hypospadias is a syndrome of penile maldevelopment. The primary goal of hypospadias surgery is to create a penis with normal appearance and function. Historically, the outcome of hypospadias repair has been assessed based on the need for reoperation due to urethroplasty complications (UC), including fistula formation, dehiscence, meatal stenosis, or development of a urethral stricture. The Glans-Urethral Meatus-Shaft (GMS) score is a standardized tool to predict UC. Analysis of the cosmetic outcomes of hypospadias repair based on the appearance of the reconstructed penis has been validated, and standardized scores have been published. The Hypospadias Objective Penile Evaluation (HOPE) score is a validated questionnaire used to assess postoperative cosmetic outcomes. Although predictors of surgical outcomes and UC have been well documented, predictors of optimal cosmetic outcomes are lacking in the literature. Furthermore, reoperation due to cosmetic considerations has been poorly reported. To identify predictors of cosmetic outcomes after hypospadias repair and to assess the reoperation rate according to cosmetic considerations. This prospective cohort study included 126 boys who underwent primary hypospadias repair. The severity of hypospadias, degree of penile curvature, glans width, preoperative HOPE, and GMS scores were documented. The standard technique for single-stage repairs, the tubularized incised plate urethroplasty, was performed. The primary endpoint was cosmetic outcomes evaluated by the HOPE score questionnaire six months postoperatively. Optimal cosmetic results were defined by HOPE scores ≥ 57. The study population consisted of the following cases: 87 (69%) subcoronal, 32 (25%) shaft, and 7 (6%) proximal hypospadias. Among the study participants, 102 boys (81%) had optimal cosmetic results (HOPE ≥ 57), and 24 boys (19%) had surgeries with suboptimal cosmetic outcomes (HOPE < 57). Ancillary procedures were performed in 21 boys (16%), of which 14 (11%) were solely for cosmetic considerations, and 7 were secondary to UC. Using the Receiver Operating Characteristic analysis of potential predictors of optimal cosmetic outcomes, the preoperative HOPE score had the highest area under the curve (AUC = 0.79; 95% CI 0.69-0.89, p < 0.001). After multivariable analysis, the degree of penile chordee (p = 0.013), glans width (p = 0.003), GMS score (p = 0.007), and preoperative HOPE score (p = 0.002) were significant predictors of cosmetic outcomes. Although meatal location predicted suboptimal cosmetic results in univariate analysis, it was not a factor in multivariable analysis. Over 80% of boys undergoing hypospadias repair achieved optimal cosmetic outcomes. More than 10% of cases underwent ancillary procedures, secondary solely to cosmetic considerations. Predictors of optimal cosmetic outcomes after hypospadias surgery included degree of chordee, glans width, and preoperative HOPE and GMS scores, which were the best predictors of satisfactory cosmetic results. Although meatal location is the main predictor of UC, it was not a predictor for cosmetic outcomes. Factors affecting cosmetic outcomes should be clearly explained to parents during the preoperative consultation.

Early Postoperative Complications of One-Stage Substitution Urethroplasty with Oral Mucosa Graft: A Monocentric Retrospective Study

Introduction: We report early postoperative complications (PCs) (≤90 days) of one-stage oral mucosa graft (OMG) urethroplasty in treatment of acquired anterior urethral strictures. Material and Methods: In this study, we evaluated 530 males who underwent one-stage substitution urethroplasty (SU) between September 1996 and October 2020. Medical records were reviewed to identify and classify early PCs based on the Clavien-Dindo classification (CDC). We subdivided the PCs into three groups with different kinds of complications which allowed us a more detailed analysis concerning general surgical complications (GSCs), donor site morbidity (DSM) and complications specific for free graft urethroplasty (CSUs). The influence of patient demographics, stricture characteristics and operative procedure on the occurrence of PCs was analysed. Results: Early (90-day) PCs occurred in 90 (16.98%) patients, whereas only 19 patients (3.58%) experienced serious events (CDC grades III and IV). Early complications include 4.5% GSCs, 1.7% DSM and 10.8% CSUs. Only stricture length turned out to be an independent statistically significant risk factor for the occurrence of early PCs. There was a trend towards a higher rate of complications in patients with ASA III compared to ASA I. Conclusion: The incidence of severe early complications in patients undergoing one-stage SU with OMG is low.

Perioperative Techniques and Long-term Outcomes in Hypospadias: A Systematic Review

Introduction: Hypospadias is a condition when the urethra distal opens on the bottom of the penis and has a ventral penile curvature. Hypospadias is the second most frequent genital birth abnormality in boys after cryptorchidism. Surgery is the standard treatment of choice and has a significant risk problem. There are many surgical procedure complications, especially in appearance and function. This article discusses the appropriate operative management and the best long-term outcome. Methods: The data was culled and selected from the ten years of full-text English publication (2012-2022) utilizing the PubMed and Google Scholar databases. Meta-analyses (PRISMA) paradigm and PICO investigation of management techniques and long-term outcomes in clinical and randomized clinical trials. Result: From 149 search articles, 7 met the inclusion criteria. The gland penis size and the meatal location did not affect the outcome of the surgical technique. However, 58/432 patients required reoperation, and 61(13%) had urethroplasty complications (UC), although not statistically significant (OR 0.8, 95% CI: 0.7-0.9). Testosterone is advised for small penises, narrow glands, thin urethral plates, and proximal hypospadias (67 vs. 87%). Preoperative antibiotics reduce the incidence of infection (17/150 repairs), tubularized incised plate (TIP), and the stent is recommended. Conclusion: The recommended strategies are good perioperative treatment, including antibiotics, testosterone treatment, surgery ages (6-18 months), tubularized incised plate (TIP) technique, and stent postoperative.

Are there anatomical limiting factors to foreskin reconstruction at the time of single-stage hypospadias repair?

Foreskin reconstruction (FR) at the time of primary hypospadias repair is a truly anatomically complete reconstruction of the hypospadic penis. We prospectively collected penile and preputial measurement of children undergoing single-stage hypospadias repair and FR with the aim to identify possible relations between penile and preputial anatomy and the likelihood to develop complications. We prospectively studied children who underwent single stage hypospadias repair associated with FR from 2016 to 2019. We recorded intra-operative foreskin and penile measurements and post-operative outcomes. Logistic Regression analysis was performed to explore independent factors affecting urethroplasty and skin complications. Chi square test was used to compare outcomes in different groups based on ventral foreskin defect (VFD) width, Glans size, age at surgery and meatal location. From a total of 181 consecutive patients, 86 boys who underwent a single stage hypospadias repair combined with FR were included in the study. Patients were excluded because they were either lost at follow up (n=10), required a 2-stage repair (n=2), were circumcised at birth (n=3) or parents requested a circumcision (n=78); in 2 patients, a decision to perform circumcision was made intraoperatively due to aesthetic reasons (monk-hood deformity of the prepuce). Median age at surgery was 17 months. Mean glans width was 14.4mm. Mean unstretched and stretched foreskin circumference were 29.5mm and 40.9mm, respectively. Mean VFD (the distance between the proximal insertion of the foreskin hood on either side of the midline at the level of the coronal sulcus) was 7.2mm (Fig.1). At median follow-up of 8 months (6-23), 9 complications were recorded (10.4%): foreskin dehiscence occurred in 1% (1/86), a foreskin fistula was noted in 4.6% (4/86), tight, non-retractile, foreskin in 1% (1/86); urethrocutaneous fistula in 2.3% (2/86) and complete dehiscence of the glans and foreskin in 1 (1.2%). Multiple logistic regression analysis demonstrated that none of the measurements obtained was an independent risk factor for developing urethroplasty or skin complications. There was no significant difference in complications between wide VFD (>7mm) vs. narrow VFD (≤7mm), large glans (>14mm) vs. small glans (≤14mm), age at surgery ≤24 months vs.>24 month and meatal location distal (glanular, coronal, subcoronal and distal penile) vs. proximal (midpenile, proximal penile and penoscrotal). To the best of our knowledge, this is the first study reporting a prospective and objective assessment of the foreskin in the context of single stage hypospadias repair. Individual anatomical differences in preputial and penile anatomy do not seem to affect the likelihood of skin and urethroplasty complications. FR can, therefore, be offered to all boys undergoing primary single stage hypospadias repair . Further studies on larger numbers and external validation of these measurements is necessary.

Introduction. Recently, there has been a tendency to perform reconstructive-plastic interventions for the treatment of both primary and recurrent urethral strictures. Buccal urethroplasty is currently recognized as the «gold standard» for the urethral strictures treatment. However, despite a large number of works on operative correction of urethral strictures using the cheek mucosa, the issues of prevention and correction of intra- and postoperative complications of buccal urethroplasty have not been finally resolved. The purpose. Using the world literature, to stydy complications, methods of their prevention and correction for improving the efficiency of primary and repeated recοnstructive-plastic οperations on the urethra using free autograft of mucous membranes οth cheeks. Materials and methods. The literature review was made using bibliographic databases: Pubmed, Web of Sience, Science Direct, Scopus, Cyberleninka, eLibrary.ru and others for the period from 1990–2022. The following keywords were used: urethral stricture, buccal graft, complications of buccal urethroplasty, buccal urethroplasty, diagnosis of complications of buccal urethroplasty, treatment of complications of buccal urethroplasty, anastomotic urethroplasty, urethroplasty replacement. In total, 150 original publications were identified and analyzed, and 104 articles of them were selected for a literary review. Results. The analysis of complications of primary and repeated buccal urethroplasty was carried out, possible options for diagnosis and correction of complications of reconstructive plastic surgery on the urethra of men using the cheek mucosa were studied and the quality of life of patients after surgical treatment was analyzed. Conclusion. The analysis of the scientific literature on the results of the surgical treatment of primary and recurrent urethral strictures using buccal mucosa graft shows that at present there is no single clinical position that would clearly classify the emerging complications of this method of uretroplastics and contributed to the development of measures for their prevention.

Double versus single diaper technique after hypospadias repair, does it really matter?

Double-diaper technique with an open-drainage catheter is a common practice after hypospadias repair. However, double-diapering may increase the burden of postoperative care and has not been compared to single-diapering with an open-drainage catheter. This study investigates whether the single-diaper technique is associated with inferior surgical outcomes compared to the double-diaper technique. A single surgeon database was retrospectively reviewed for patients who underwent hypospadias repair between 2013 and 2021. Patients who were lost to follow-up and those in whom the type of diaper care (single- or double-diaper) was not documented were excluded. Patients in the single-diaper technique received the same type of dressing and discharge instructions, as those in the double-diaper group, except for leaving the catheter freely draining into a single-diaper. Short-term complications including surgical site infection (SSI), urinary tract infection (UTI) and wound dehiscence, were the primary outcome; whereas the long-term urethroplasty complications (urethrocutaneous fistula and meatal stenosis) were secondary outcomes. Outcomes were analyzed according to the type of diaper care. Among 323 patients reviewed, 219 patients met the inclusion criteria (72 patients in the double-diaper and 147 in the single-diaper group). Both study groups were similar regarding patient demographics, hypospadias characteristics and surgical technique. Looking at the primary outcomes, there was no statistically significant difference in SSI, UTI or wound dehiscence. For the secondary outcomes, the incidence of meatal stenosis (8.3 vs. 1.4%, p=0.044), and fistula formation (15.3% vs 5.4%, p=0.037) was significantly higher in the double-diaper than the single-diaper group, respectively (Table 2). Single-diaper technique following hypospadias repair is not associated with increased risk of complications compared to double-diaper technique.

The Role of Postoperative Dressing in Hypospadias Surgery: A Systematic Review and Meta-analysis of the Pediatric Literature.

This study aimed to describe the available dressings and their management in patients undergoing hypospadias repair and compare postoperative outcomes with and without dressing and between the different dressing types. A comprehensive electronic literature search of PubMed, Embase, and Cochrane Library was conducted to obtain studies, published in the period 1990 to 2021, reporting on the dressing used following hypospadias surgery. All information regarding the dressing was considered as primary endpoints, whereas surgical outcomes were assessed as secondary outcomes. Thirty-one studies containing 1,790 subjects undergoing hypospadias repair were included. Dressings were divided into three categories: nonadherent to the wound, adherent to the wound, and glue-based dressings. Most authors preferred to remove/change the dressing in the ward and the median time of removal/change was 6.56 postoperative days. The dressing removal appeared as the most frequent factor generating parental anxiety. The median rate of wound-related complications was 8.18%, of urethroplasty complications 9.08% and of reoperations 8.18%. Meta-analysis of outcomes showed higher risk of reoperations using conventional dressing, with no differences in urethroplasty and wound-related complications rates between conventional and glue-based dressings. Furthermore, the use of dressing reported increased risk of wound-related complications compared with no dressing, without significant differences regarding occurrence of urethroplasty complications and reoperations. The current evidence confirmed that there is no difference in outcomes of hypospadias repair depending on a certain dressing type. To date, surgeon's preference remains the main factor determining the choice for a specific dressing or for no dressing at all.

This practice is not evidence-based, and some families get stressed about this particular step of postoperative care. This study hypothesizes that the single-diaper technique offers similar surgical outcomes compared to the double-diaper technique. METHODS: A single surgeon database was retrospectively reviewed for patients who underwent hypospadias repair between 2013 and 2021. Patients who were lost to follow-up and those in whom the type of diaper care (single or double diaper) was not documented were excluded. Patients in the single-diaper technique received the same type of dressing and discharge instructions, as those in the double-diaper group, except for leaving the catheter free inside the single diaper. Short-term complications including: surgical site infection (SSI), urinary tract infection (UTI) and wound dehiscence were the primary outcome; whereas long-term urethroplasty complications were secondary outcomes. Outcomes were analyzed according to the type of diaper care. RESULTS: Among 323 patients reviewed, 219 patients met the inclusion criteria (72 patients in the double-diaper and 147 in the single-diaper group). Both study groups were similar regarding the age at surgery, follow-up duration, type of hypospadias, associated chordee and surgical technique. Looking at the primary outcomes, there was no statistically significant difference in SSI, UTI or wound dehiscence rates between the study groups. Only one dehiscence was reported in the single-diaper group for a patient with myelomeningocele who required self-catheterization. For the secondary outcomes, the incidence of meatal stenosis (8.3 vs. 1.4%, p=0.044), and fistula formation (5.4 vs. 15.3%, p=0.037) was significantly higher in the double-diaper than the single diaper group, respectively. Patient demographics and surgical outcomes are summarized in table 1. CONCLUSIONS: Single-diaper technique for hypospadias repair is simple, easy, and is not associated with increased risk of complications compared to double-diaper technique.

Associations between suturing techniques and suture materials with complications of tubularised incised plate urethroplasty: A systematic review and meta-analysis

Tubularised incised plate (TIP) urethroplasty has received widespread acceptability for hypospadias repair. Differences in surgical approach might impact the outcome of TIP urethroplasty. This study was performed to examine the associations between suturing techniques and suture materials with complications of TIP urethroplasty. Following electronic databases: PubMed, ScienceDirect, EMBASE, and Cochrane Library were systematically reviewed for the studies that reported comparisons of interrupted and continuous suturing techniques and comparisons of several suture materials with complication rates during TIP urethroplasty. Risks of bias were evaluated with RoB 2 tool for randomised controlled trials (RCTs) and ROBINS-I tool for comparative non-RCTs. All data were analysed utilising review manager 5.4. Thirteen total studies involving 2,967 patients underwent TIP procedure were included in this study. However only nine studies fulfilled the criteria for quantitative synthesis. In meta-analysis, there was no significant difference of total complications rate among interrupted and continuous suturing techniques (OR 0.86; 95% CI: 0.46–1.59). Subgroup analysis for each complications (urethrocutaneous fistula, infection, dehiscence, meatal stenosis, and urethral stricture) were also not statistically different. The utilisation of absorbable synthetic braided suture compared to monofilament sutures did not increase the complications rate of TIP urethroplasty (OR 1.49; 95% CI: 0.83–2.68). No publication bias was observed in the funnel plot. Our meta-analysis showed that suturing techniques and suture materials had no significance on the complications of TIP urethroplasty. The selection of suturing techniques and suture materials should be based on surgeons or centre's local experience.

Reoperation frequency after transverse preputial Island flap urethroplasty "Duckett's technique" in treatment of severe hypospadias: A single center study.

Transverse Preputial Island Flap Urethroplasty (TPIFU) is one of the most common techniques for treating severe hypospadias. Studies on the reoperation frequency after TPIFU is lacking. In the present study, we reported our clinical outcomes of severe hypospadias treated with one-staged TPIFU and analyzed the operation frequency. We retrospectively analyzed the clinical data of severe hypospadias patients who underwent one-stage TPIFU from December 2018 to December 2019 in the department of Urology at Beijing Children's Hospital. A stepwise approach was used to manage the curvature. Severe hypospadias was defined as those residual curvature was higher than 30° after degloving. Urethroplasty complications included fistula, urethral stricture, and diverticulum. The short-term cure was identified as no complications occurring for 12 months after the date of last-time surgery. The reoperation rate and operation frequency of TPIFU were analyzed. A total of 136 patients who underwent one-stage TPIFU were included in the study. The follow-up after primary urethroplasty ranged from 22 to 50 months. The median age at primary surgery was 22.5 months (range from 13 to 132 months). After primary TPIFU surgery, 53 (39%) patients underwent additional surgical interventions to treat postoperative complications. Among them, 24 patients (17.6%) developed fistula, 17 patients (12.5%) developed urethral stricture and 11 patients (8.1%) developed diverticulum. After the second surgery, five patients remained fistula, five patients remained urethral stricture, and seven patients remained diverticulum. Overall, 61% (85 patients) met the cured standard after the primary operation, and the two operations cure rate was 87.5% (119 patients). 91.2% (124 patients) were cured in three operations. Although the complication rates after primary TPIFU were relatively high, more than half of patients achieved short-term cured through a single operation, and the cure rate after two or three operations was acceptable.

The modified Belt-Fuqua procedure using an asymmetric “furisode” sleeve for proximal hypospadias with severe curvature

Proximal hypospadias repair is a challenge in the pediatric urology field. Although the previous reports showed that the Belt-Fuqua staged procedure is reliable with a low complication rate for midshaft hypospadias, this procedure has not been generally applied to more proximal hypospadias with severe ventral curvature due to technical limitations. To solve these technical limitations, we developed a modified Belt-Fuqua procedure using an asymmetric long skin sleeve looking like a Japanese long-sleeved Kimono called a "furisode". The aim of this study was to evaluate the outcomes of this new modification of the Belt-Fuqua procedure for the repair of proximal hypospadias with severe curvature in children. The study retrospectively reviewed consecutive patients with proximal hypospadias with severe curvature underwent this new technique. The major modifications included are proximal degloving beyond the urethral meatus, asymmetrical ventral transposition of dorsal preputial skin like a furisode sleeve, and circumferential proximal anastomosis of preputial skin to native meatus in the first stage. Hypospadias severity was evaluated objectively in two ways: preoperatively by the Glans-Urethral Meatus-Shaft score and intraoperative direct measurement of ventral curvature. The primary outcome was urethroplasty complications. A total of 66 patients completed both stages of the furisode technique. The median Glans-Urethral Meatus-Shaft score was 11. Overall, 60 (91%) patients showed ventral curvature greater than 60 degrees after degloving, and 35 (53%) underwent ventral grafting with a dermal graft in the first stage. Median urethral length constructed at the second stage was 41.5mm. The median follow-up period was 25 months. Complications occurred in 9 patients (14%); 7 had urethral diverticula, 1 showed a fistula and 1 had a urethral stricture. Neither glans dehiscence nor meatal stenosis occurred. There are a couple of advantages of this furisode technique to other tunneled flap techniques like the Ulaanbaatar procedure. The first is the ease of glans reshaping with a Firlit collar at the first stage because of no urethra in the glans. The second is that a long neourethra could be made by the same skin flap with one anastomosis to the native urethra.The weakness of this procedure was that urethral diverticula were prone to occur less than one year after urethroplasty. The furisode technique, a new modification of the Belt-Fuqua procedure, provides an alternative staged repair of proximal hypospadias. This technique was easily applied for hypospadias with severe curvature requiring ventral grafting.

ОПТИМИЗАЦИЯ УХОДА ЗА ХИРУРГИЧЕСКОЙ РАНОЙ ПОСЛЕ УРЕТРОПЛАСТИКИ У ДЕТЕЙ С ГИПОСПАДИЕЙ

Objectives. To develop optimal postoperative wound care tactics for boys with hypospadias. Methods. The patients (128) with hypospadias aged from 11 months to 7 years were examined. The main group A consisted of 83 (64.8%) patients in whom we used a special bandage. It includes layer by layer of soft polyamide net two-sided onlay coated with soft silicone and adhesive properties, abundantly treated with an antimicrobial ointment containing an osmotic agent, sterile absorbent wipes with non-woven material, a circularly applied elastic bandage and an adhesive plaster with porous non-woven material. The dressing usually held up to 5 days. Group B included 45 (35.2%) patients with hypospadias, in whom we used a conventional sterile circular gauze bandage with antimicrobial ointment. The gauze bandage changed daily. For all clinical symptoms the groups were comparable in age. Postoperative wound healing had been monitored for 10 days after urethroplasty. The emphasis was made on such criteria as bleeding with hematoma formation, copious exudate excretion, penis skin hyperemia, «soft» and «dense» edema, drying crust (scab), skin sutures dehiscence, hypergranulation and necrosis. Results. In group A, problems with the skin flap and postoperative wound were detected only in 17 (20.5%) boys on the second or third day after removal of the special bandage. In the postoperative period, 41 (91.1%) patients in group B had «painful» skin changes in the area of the postoperative wound, which appeared almost the next day after surgery. Conclusion. The use of special bandage delays in time the contact of microbiota penis tissues compromised by surgery and the external environment, which, no doubt, improves the healing of skin grafts in the early postoperative period, and therefore reduces the number of urethroplasty complications. What this paper adds For the first time in patients with hypospadias, the process of postoperative wound healing was analyzed depending on the type of dressing. It was established that the use of a long-term bandage with a soft polyamide mesh doublesided pad with a silicone contact layer and adhesive properties compared to a traditional gauze bandage, which was changed daily, optimized the tactics of postoperative wound care in boys with hypospadias and minimized the number of urethroplasty complications.

Urethral complex thickness and thickness index are the independent risk factors for urethroplasty complications after tubularized incised plate hypospadias repair

In tubularized incised plate urethroplasty, the depth of the mid-line relaxing incision is the key factor for urethral plate tubularization without tension. The incision depths will be different from one case to the other even if they have been done by the same surgeon. This difference in depths resulted from the different thicknesses of the urethral plate and the underlying corpus spongiosum (urethral complex). To evaluate the urethral complex thickness and thickness index as risk factors for the complications of TIPU in penile shaft hypospadias repair. All primary penile shaft (distal and mid-penile) hypospadias (with or without mild penile chordee) were operated with TIPU between March 2018 and February 2021. We measured the urethral complex thickness in the hypospadiac and proximal normal parts of urethra pre-operatively with superficial U/S probe. Intraoperative, we measured the urethral plate width before and after the midline relaxing incision, calculate the relative increase in urethral plate width (RIUPW). Stepwise logistic regression assessed the effect of different variables on the complication rate. These variables include; urethral plate width before and after incision, urethral complex thickness, thickness index, RIUPW, site of hypospadiac meatus and patients ages. 10 cases had 11 complications (12.7%). Fistulae were the commonest complication (8.9%). Complication rate has significant negative correlations with many variables on Univariate analysis. Stepwise logistic regression shows that urethral plate thickness and thickness index are the independent risk factors for complications after TIPU in penile shaft hypospadias. Urethral plate width was suggested to be a risk factor for TIPU complications. In our study, Univariate analysis shows that complications were more with plate width ˂8mm but without significant difference (P=0.487). Also it shows that post incision width and RIUPW have significant negative correlation with complications rate. Multivariate analysis showed that the urethral complex thickness and thickness index are the independent risk factors for complications after TIPU hypospadias repair (AUC 0.94 95% CI 0.894-0.972P˂0.001 and 0.965 95% CI 0.921-0.996, respectively). The thickness of the urethral plate and the underlying spongiosum is the determining factor for TIPU success. We can use it as an objective reproducible assessment tool for urethral plate quality and to predict TIPU complications.

Randomized trial of prophylactic antibiotics vs. placebo after midshaft-to-distal hypospadias repair: the PROPHY Study

Use of prophylactic antibiotics after stented hypospadias repair is very common, but most research has not identified any clinical benefits of this practice. Only one study has found that postoperative prophylaxis reduces symptomatic urinary tract infections (UTIs). Data from the same trial suggested that prophylaxis may also reduce urethroplasty complications. No studies on this subject have been placebo-controlled. We performed a randomized, double-blind, placebo-controlled study to evaluate the effect of postoperative prophylactic antibiotics on the incidence of infection or urethroplasty complications after stented repair of midshaft-to-distal hypospadias. Boys were eligible for this multicenter trial if they had a primary, single-stage repair of mid-to-distal hypospadias with placement of an open-drainage urethral stent for an intended duration of 5-10 days. Participants were randomized in a double-blind fashion to receive oral trimethoprim-sulfamethoxazole or placebo twice daily for 10 days postoperatively. The primary outcome was a composite of symptomatic UTI, surgical site infection (SSI), and urethroplasty complications, including urethrocutaneous fistula, meatal stenosis, and dehiscence. Secondary outcomes included each component of the primary outcome as well as acute adverse drug reactions (ADRs) and C. difficile colitis. Infection or urethroplasty complications occurred in 10 of 45 boys (22%) assigned to receive antibiotic prophylaxis as compared with 5 of 48 (10%) who received placebo (relative risk [RR], 2.1; 95% confidence interval [CI], 0.8 to 5.8; p=0.16). There were no significant differences between groups in symptomatic UTIs, SSIs, or any urethroplasty complications. Mild ADRs occurred in 3 of 45 boys (7%) assigned to antibiotics as compared with 5 of 48 (10%) given placebo (RR, 0.6; 95% CI, 0.2 to 2.5; p=0.72). There were no moderate-to-severe ADRs, and no patients developed C. difficile colitis. In this placebo-controlled trial of 93 patients, prophylactic antibiotics were not found to reduce infection or urethroplasty complications after stented mid-to-distal hypospadias repair. The study did not reach its desired sample size and was therefore underpowered to independently support a conclusion that prophylaxis is not beneficial. However, the result is consistent with most prior research on this subject. NCT02096159.

Acellular dermal matrix graft for ventral corporal lengthening orthoplasty in 2-stage proximal hypospadias repair.

BackgroundCorrecting ventral curvature (VC) by lengthening the ventral corpora using a graft has been verified feasible, but still has been associated with the recurrence. The use of acellular dermal matrix (ADM) in the setting of tissue reconstruction has captured the attention of many surgeons. There are few reports on the use of ADM exclusively as correction of VC. Thus, we evaluate the safety and effectiveness of repairing the defect with ADM for straightening the VC in proximal hypospadias repair.MethodsWe retrospectively analyzed the records of patients with proximal hypospadias who underwent ventral corporal lengthening with graft in staged repair from January 2013 to December 2019. Those with curvature greater than 30° after urethral plate transection were enrolled. ADM was used for repairing the defect left by transversely transection of tunica albuginea. Patient outcomes were compared with the non-matched control group who underwent the same procedure with tunica vaginalis (TV) repair. Patient demographics, operative techniques, complications, reoperations were summarized and compared between 2 groups.ResultsForty-three patients underwent ventral lengthening with ADM repair after transverse urethral plate transection and 35 patients with TV patching respectively. At a mean follow-up of 10 months in those with the first-stage ventral lengthening, 5 of 43 (11.6%) in ADM group was detected with recurrent VC, while 2 of 35 (5.7%) in TV group were observed with recurrent curvature contemporarily (P=0.363). At a mean follow-up of 46.8 and 45.3 months, persistent curvature in ADM group was not significantly different comparing to TV group (1/43, 2.3% vs. 1/35, 2.9%; P=0.883).ConclusionsVentral corporal lengthening using ADM graft may facilitate correction of VC without increasing the risk of urethroplasty complications. It offers a promising material that can be safe, effective and simple to use and provides psychological and aesthetic benefits. Additional series assessment and further randomized controlled trials will elucidate the clinical impact of using ADM with ventral lengthening.

Первый опыт использования фибринового клея при хирургическом лечении гипоспадии у детей

Introduction. Hypospadias is one of the most common malformations of the external genital organs in boys. The development of surgical technologies in recent decades has significantly improved the functional and cosmetic results of hypospadias treatment. Nevertheless, complications of urethroplasty are still the most discussed issue of this problem. To prevent fistulas and urethral dehiscence, it has been proposed to cover the suture line with a single or double layer of dartos fascia from a de-epithelized foreskin. For a similar purpose, it has been also suggested using the fibrin glue to seal the sutures of the formed urethra. The objective of this study was to prospectively evaluate the efficacy of Evicel fibrin glue in the surgical treatment of distal hypospadias in children. Materials and methods. The study included 27 children under the age of 2 years (between 11 and 23 months) with coronary hypospadias. All children underwent tubularized incised plate surgery. The first group of patients comprised 11 (40.7%) children whose urethra was covered with Evicel fibrin glue after tubularization. Covering of urethra with two sheets of de-epithelized foreskin was performed in the second group, in 16 (59.3%) children. Results. We have not revealed statistical differences in the occurrence of complications in the studied groups of patients. In the first group, a fistula of the urethra was noted in 1 (9.1%) child, in the second group, 2 (12.5%) complications were revealed. Conclusion. From our perspective, the absence of differences in the complications rares in the studied groups of patients. We may conclude that the use of Evicel glue is as effective as covering the neourethra with a de-epithelialized foreskin flap.

The association between caudal block and urethroplasty complications of distal tubularized incised plate repair: experience from a South China National Children's Medical Center.

BackgroundThe effect of caudal block (CB) on the incidence of urethroplasty complications in hypospadias repair remains controversial. The evidence is conflicting, and some confounding bias issues need to be addressed. We sought to study a more homogenous group of distal hypospadias patients undergoing primary tubularized incised plate (TIP) repair by a senior pediatric urology surgeon in the past 2 years to examine the relationship between urethroplasty complications and the use of CB.MethodsWe reviewed our database to identify consecutive patients who had undergone hypospadias repairs by a senior director surgeon at our Center between January 2018 and November 2020. To be eligible to participate in the study, patients had to meet the following inclusion criteria: (I) have distal hypospadias; (II) have undergone a primary TIP repair; and (III) have attended follow-up appointments for a minimum period of 6 months. The primary outcome was the development of urethroplasty complications during the follow-up period. The principal variable of interest was whether or not CB was used perioperatively. The patients were categorized into a CB group (general anesthesia combined with CB) or a control group (general anesthesia only). Other potential risk factors were analyzed, including patient age at operation, patient weight, glans width, and the length of the urethral plate defect.ResultsThirty (12.2%) of the distal patients developed postoperative surgical complications. The postoperative surgical complication rates were similar between the different anesthesia groups. Weight, the length of the urethral plate length, and glans width did not contribute to the risk. Age was the only independent risk factor for postoperative surgical complications, and the complication rates increased in older patients.ConclusionsOur data from consecutive TIP repairs in distal hypospadias patients indicated no association between the use of CB anesthesia and the postoperative urethroplasty complication rate. Patients who were older in age when they underwent surgery had a higher risk of complications.
