Anterior and Mid-Penile Hypospadias Repair with TIP Technique—Is It Possible with 20-Hour Catheterization?

Background/Objectives: Several surgical procedures have been proposed for the treatment of hypospadias, a common and heterogeneous congenital abnormality in males. Most surgeons utilize either a urethral stent or bladder catheter for 2–14 days as a postoperative urine diversion method depending on the severity of each case and the surgeon’s preferences. The aim of the present study was to evaluate the feasibility of anterior and mid-penile hypospadias repair while placing the urethral catheter for only 20 h. Methods: A single-centre retrospective study was conducted, including all patients who underwent anterior or penile hypospadias repair from January 2012 to January 2023. All operations were performed based on the Tubularized Incised Plate (TIP) Urethroplasty. At the end of the operation, a 6 Fr 100% silicon catheter was stabilized. The catheter was removed 20 h postoperatively, and all patients were discharged on the first postoperative day. The primary endpoint of the study was the complication rate. Results: In total, 104 patients were enrolled. Eighty (76.9%) patients presented with distal penile hypospadias, while 24 patients (23.1%) had mid-penile hypospadias. The mean age at the operation was 20.8 ± 12.4 months, while the mean operative time was 114.2 ± 28.7 min. All the operations were successfully completed. During the follow-up period (mean duration 101.1 ± 44.8 months), complications were recorded in 16.3% of the patients. Conclusions: The application of 20-h catheterization seems to be an effective alternative with outcomes comparable to other conventional drainage approaches, as it reduces the discomfort of the patients without increased risk of complications.

Scoring System for Evaluating Cosmetic Appearance in Operated Hypospadias Patients

Background: Hypospadias is a common congenital anomaly affecting male infants, characterized by abnormal positioning of the urethral meatus. Surgical correction aims to achieve both functional and cosmetic outcomes.Objective: To evaluate the cosmetic outcomes of hypospadias surgery using a standardized scoring system.Methods: A prospective observational study was conducted at Shaheed Mohtarma Benazir Bhutto Institute of Trauma from January to July 2023, including 154 male infants and young children who underwent primary hypospadias repair.The surgeries performed were Tubularized Incised Plate (TIP) urethroplasty, Onlay Island Flap, and Mathieu repair. Cosmetic outcomes were assessed using the Hypospadias Objective Scoring Evaluation (HOSE) system. Data were analyzed using SPSS version 25.Results: The mean age at surgery was 2.8 years. Distal hypospadias was most common (62%), followed by midshaft (28%) and proximal (10%). TIP urethroplasty had the highest mean HOSE score (15.4 ± 1.0), with 86% achieving satisfactory outcomes. Onlay Island Flap scored 14.9 ± 1.2, and Mathieu repair scored 14.2 ± 1.5. Residual penile curvature was noted in 15% and scarring in 12% of cases.Conclusion: TIP urethroplasty yielded the most favorable cosmetic outcomes in distal hypospadias. Standardized scoring systems are crucial for evaluating surgical success.

Late chordee correction after tubularized incised plate repair for proximal hypospadias: An underreported problem

AbstractBackgroundRepair of proximal hypospadias remains a challenge with no consensus on the best surgical approach. Several reports have shown recurrence of chordee after plate‐preserving techniques. In this report, we present our experience in managing cases who presented with persistent/recurrence of chordee after tubularized incised plate (TIP) repair for proximal hypospadias.MethodsBetween 2015 and 2023, the study included eight patients who presented with ventral penile curvature after previous hypospadias repair in infancy (TIP urethroplasty). Reoperation to correct persistent ventral curvature was performed several years after the primary TIP repair (3–15 years; mean 7.9 years; median 7.5 years). The reoperation was a two‐stage procedure: the first stage comprised transection of the urethra and grafting (lower lip mucosal graft); the second stage (6 months later) was a Thiersch‐Duplay urethroplasty.ResultsComplications included poor taking of the graft after the first stage in one case (12.5%), which was regrafted using buccal (cheek) mucosa. Complications after second stage included urethro‐cutaneous fistulae in five (62.5%) that were successfully surgically treated at a later stage. Follow‐up after second stage ranged between 6 months and 7 years (mean 2.4 years; median 1 year). Satisfaction with reoperation to correct penile curvature was noted by parents as well as older children (adolescents) who appreciated better cosmesis by increasing ventral penile length and improved curvature.ConclusionPreservation of the urethral plate in proximal hypospadias may result in shortened penile length, mostly on the ventral aspect. A two‐stage reoperation to increase the length of the penile urethra can successfully reverse this complication.

Comparison between tubularisation of an intact and laterally augmented urethral plate urethroplasty and tubularised incised plate (TIP) urethroplasty for hypospadias repair

Objectives: The aim of this study was to compare the outcome of hypospadias repair by tubularisation of an intact and laterally augmented urethral plate urethroplasty and TIP urethroplasty. Methods: This prospective comparative study was conducted from July 2018 to January 2020 and included 35 patients with primary distal and mid penile hypospadias. All had urethral plate widths of 8–10 mm. Exclusion criteria were mega meatus intact prepuce, previous repair, circumcision, urethral plate of >10 mm or <8 mm in diameter, chordee >30°. In Group A underwent tubularisation of an intact and laterally augmented urethral plate urethroplasty and in Group B underwent tubularised incised-plate (TIP) urethroplasty. The follow up period was 06 months. Results: The success rate without any complication was 88.89% and 76.48% in Group A and B respectively. Meatal stenosis occurred 0% and 11.76% in Group A and B respectively. Wound dehiscence rate was 5.55% and 5.88% in Group A and B respectively. Urethrocutaneous fistula occurred 5.55% and 5.88% in Group A versus Group B. Overall complication occurred 11.11 in Group A and 23.52% in Group B. Conclusion: The outcome of tubularisation of intact and laterally augmented urethral plate urethroplasty was better than TIP urethroplasty.

Widening of narrow urethral plates with lateral skin in TIP hypospadias repair: single center series

BackgroundTo compare the outcomes of hypospadias repair using tubularized incised plate (TIP) urethroplasty and modified TIP with lateral skin to widen the urethral plate (WTIP).Materials and methodsData were obtained from pre-pubertal boys who underwent primary hypospadias repair between May 2018 and July 2023. The cases were divided into two groups; one group underwent TIP with urethral plate ≥ 6 mm width and the other group with urethral plate width < 6 mm underwent WTIP. WTIP urethroplasty was performed by widening incisions on the outer margins of the urethral plate to incorporate penile and glandular skin lateral to the urethral plate to facilitate tubularization. Complication rates and urinary functions were compared.ResultsA total of 157 patients were enrolled in this study. Eighty-eight cases with narrow urethral plate were subjected to WTIP urethroplasty, and the rest were subjected to TIP urethroplasty. The preoperative glans width in WTIP group was less than that in TIP group (P < 0.001), and 44.3% had midshaft meatus in WTIP group compared to 17.4% in TIP group (P < 0.001). However, the incidences of postoperative complications (17.6% vs. 21.6%, P = 0.550) were not statistically different between the TIP and WTIP groups. In addition, both groups did not differ significantly in postoperative uroflowmetry assessment.ConclusionsThe described technique helps to create an adequately caliber aesthetic neomeatus and facilitates tubularization, especially in hypospadias with a narrow urethral plate. Our data suggest that augmentation of a narrow urethral plate with WTIP has a similar surgical outcome to that of the TIP procedure in patients with a wide urethral plate.

Cumulative sum learning curve analysis of tubularized incised plate repair for hypospadias: a study of a single surgeon with a single surgical procedure.

To ascertain the quantity of instances by which a single surgeon achieves competency and proficiency in using tubularized incised plate (TIP) technique for the repair of distal and mid-shaft hypospadias using the cumulative sum (CUSUM) analysis. We retrospectively evaluated patients with distal and mid-shaft hypospadias who were treated by a single surgeon between 2015 and 2021, using a single primary TIP technique with a de-epithelialized Byars flap. Data including type of hypospadias, age at surgery, curvature, operation time (OT), length of the reconstructed urethra, and postoperative outcomes were collected and assessed. CUSUM was used to assess the trends in OT and complication rate (CR) in order to generate the learning curve. The evolution of OT and CR can be divided into three phases: learning, competence, and proficiency. CUSUM identified three phases in the learning curves of all TIP repairs. The median OT decreased from 135 min [interquartile range (IQR) = 125-155] to 92 min (IQR = 80-100) (P < 0.001), CR decreased from 28 (28%) to 8 (5.3%) (P < 0.001), and reoperations decreased from 15 (15.2%) to 4 (2.6%) (P < 0.001). According to the CUSUM learning curve, technical competency plateaued after the 99th case, and both OT and CR entered a significantly declining proficiency phase after the 231st case. Further, when the neourethral length exceeded the total average, total complications, urethrocutaneous fistula, and reoperations increased (P = 0.013, P = 0.006, and P = 0.028, respectively). Our study suggests that surgeons performing TIP repair may reach technical competency and achieve proficiency after operating on 99,231 cases, respectively. Moreover, the longer the neourethral length, the higher is the CR.

Reducing fistula rate in hypospadias repair: A comparative study between standard tubularized incised plate repair and incorporation of a layer of spongiosum tissue

The most prevalent complication in hypospadias repair is fistula formation. Adhering to the principle of providing urethroplasty coverage to mitigate fistula occurrence, we implemented a modification by integrating a spongiosum layer between the urethroplasty and the dartos flap. Our hypothesis posited that this approach would result in a reduced fistula formation rate. This study is a comparative analysis involving patients under 18 years of age who underwent primary hypospadias repair. The cases were allocated into two groups. In the study group, in addition to performing tubularized incised plate (TIP) repair, a spongiosum layer harvested from both sides of the urethra was used to cover the urethroplasty (modification of the Y-to-I urethroplasty). The control group underwent a standard TIP repair. The primary outcome was to assess urethrocutaneous fistula formation. Secondary outcomes included evaluating the development of meatal stenosis and glans dehiscence, along with assessing cosmetic results by the Hypospadias Objective Penile Evaluation (HOPE) score. Overall, 154 hypospadias cases were included in the study. Eighty-seven patients (56%) were allocated to the study group, and 67 (44%) were allocated to the control group. Urethrocutaneous fistula developed in 3 (3.4%) and 11 (16.4%) patients in the study and control group, respectively (p=0.006). Glans dehiscence occurred in 2 (2.3%) patients in the study group and 4 (6%) patients in the control group (p=0.198). Meatal stenosis was observed in 4 (4.6%) patients in the study group and 5 (7.5%) patients in the control (p=0.452). The mean HOPE score was 59 in both groups (p=0.36). This study details our encounters with the novel modification and compares the results with standard TIP. Our data suggest that adding a layer of spongiosum tissue over the urethroplasty reduces the complication of urethrocutaneous fistula without increasing the occurrence of dehiscence, significant meatal stenosis, or compromising cosmetic outcomes. We advocate for implementing the described surgical modification as a viable option for hypospadias repair.

Correction of curvature in single stage hypospadias repair with foreskin reconstruction

Many surgeons offer foreskin reconstruction (FR) as a routine part of hypospadias repair. We present a step-by-step video of the procedure of Tubularised Incised Plate (TIP) repair, FR and dorsal plication through a ventral skin incision. A ventral incision is made between the inner preputial mucosa and the outer skin extending below the meatus. Ventral degloving is carried out. The dissection is extended laterally around the corporal bodies. The point of maximal curvature (PMC) is marked on the dorsal midline. A vertical incision is made and closed transversely with 5-0 prolene suture in a Heineke- Mikulicz fashion. Urethroplasty is performed in 2 layers using 7-0 polydioxanone (PDS). Spongioplasty and ventral dartos are used as barrier layers. Glansplasty is performed in 2 layers.FR is carried out in 3 layers. Curvature correction is key to good outcome. Dorsal degloving can be achieved through a ventral incision allowing exposure of the dorsal midline for plication sutures. The patient had good cosmetic and functional outcome at 1 month follow up. FR can be safely performed during TIP repair for distal hypospadias repair. Curvature of less than 30° can be corrected through a ventral incision only.

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.

Surgical Repair of Mid-penile to Distal Hypospadias in Children; Report of 93 Cases

Objective: To present the single surgeon’s experience in surgical repair of mid-penile to distal hypospadias in a series of 93 cases.&#x0D; Methodology: This is a retrospective study of management of patients of mid penile to sub coronal hypospadias at a median age of 24 months between June 2011 to August 2021. All the children were followed up for 6 months. Eighty-three children were between the age of 1 to 4 years and 10 children were from the age of 5 to 8 years. All the patients underwent physical examination to confirm the diagnosis and to exclude associated anomalies. All the children having mid penile to sub coronal hypospadias were included. All children with glanular hypospadias were excluded from the study. The repair was done under general anesthesia while using tubularized incised plate (TIP) technique.&#x0D; At completion of surgery compression dressing with transparent Tagaderm was used for one week in all the patients.&#x0D; Results: All of 90 patients had excellent cosmetic and functional outcome. Only 3 patients developed fistula which needed surgical intervention.&#x0D; Conclusion: Surgical repair of mid penile to sub coronal hypospadias by tubularized incised plate (TIP) technique is safe and effective. Compression dressing with transparent Tegaderm prevents complications of hematoma formation and wound infection.

Patient Perspectives and Outcomes in Adult Hypospadias Repair.

Background Hypospadias is a common congenital anomaly that needs repair at an early age (six months to one year). Ironically, many cases in India present late due to a lack of healthcare facilities, poverty, and illiteracy. Adult patients are different from children as they are aware of their genitalia. They are concerned with the aesthetics and, predominantly, the potency. In this study, we present the perspectives and outcomes of 111 adult cases of hypospadias. Methodology In this retrospective study conducted between January 2010 and December 2020, 111 patients aged more than 14 years who were diagnosed with hypospadias of any level with or without mild-to-moderate chordee were included. Hypospadias repair using a tubularized incised plate (TIP) urethroplasty technique was performed, and patients after surgery were followed up at three months, six months, and 12 months for any complications with physical examination, uroflowmetry, and patient-related outcomes (PROs). Results Age varied from 14 years to 32 years (mean = 19.88 years, SD = 5.93). The most frequent meatus positions after chordee adjustment were distal (n = 64, 57.65%), middle (n = 25, 22.52%), and proximal (n = 22, 19.82%). Among these, four patients had penoscrotal transposition. Chordee was present in 65.7% (n = 73) of the cases. (<30° in 38.7%, n = 43; 30°-60° in 23.4%, n = 26, and >60° in 3.6%, n = 4). Chordee was corrected using many techniques, including ventral corporotomies. Urethroplasty was done using TIP and spongioplasty in 89% (n = 99), and one patient underwent inner preputial onlay flap urethroplasty. Snodgraft was used to augment the urethral plate in 10 cases. The success rate of one-stage surgery was 74.77% in our series, which significantly correlated with PROs. Uroflow varied from 12 mL/second to 18 mL/second, and in the majority of the cases, the flow rate improved over time. The most common complication was urethrocutaneous fistula in 11 (11.8%) patients, followed by glanular dehiscence in nine (8.1%) patients. Conclusions Adult patients undergoing primary hypospadias repair generally show good outcomes. Patients can have an acceptable mild degree of residual chordee and torsion, which correlate well with PROs. In our series, hypospadias fistula was the most common complication of hypospadias surgery, followed by glanular dehiscence.

Comparison of the efficacy and safety of dorsal inlay graft urethroplasty (DIGU) method with tubularized incised plate urethroplasty (TIPU) method in primary distal hypospadias repair: a systematic review and meta-analysis

Link of Video Abstract: https://youtu.be/r399GEt3guoIntroduction: Tubularized Incised Plate Urethroplasty (TIPU) is a technique that is widely used in distal hypospadias repair. The advantages possessed by this technique are better cosmetics, the meatus is at the tip of the penis, and the phallus is straight. Some researchers believe that a urethral plate with a size of less than 8 mm is unsuitable for the TIPU technique so augmentation with a graft using the dorsal inlay graft urethroplasty (DIGU) technique is needed. To date, there have been no systematic reviews and meta-analyses that have directly compared the efficacy and complications of DIGU and TIPU. Therefore, this study aimed to compare the effectiveness and complications of these two modalities for repair in primary distal hypospadias patients. Methods: This study is a systematic review study and meta-analysis. The protocol for conducting and compiling this study was based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A systematic search was performed on six databases: PubMed, Scopus, Web of Science, ProQuest, Cochrane Central Register of Controlled Trials (CENTRAL) and ClinicalTrials.gov. The risk of bias in the study will be analyzed using the Cochrane Risk of Bias Tools for Randomized Trials version 2 (RoB 2). Results: Six studies that met the inclusion criteria were included in the meta-analysis with a total of 381 samples. The success rates (OR 1.46, 95% CI 0.74-2.87, p = 0.28) and urine output (OR 2.54, 95% CI 0.63-10.20, p = 0.19) were not significantly different, while the mean operating time (MOT) (SMD 1.96, 95% CI 1.10-2.82, p &lt; 0.0001) was significantly shorter in TIPU (P &lt; 0.05). The incidence of meatal stenosis was significantly more in TIPU than DIGU significantly (OR 5.11, 95% CI 1.46-17.92, p = 0.01), while fistula (OR 2.93, 95% CI 0.92-9.35, p = 0.07) and dehiscence (OR 3.05, 95% CI 0.81-11.45, p = 0.10) was not significantly different between the two techniques. Conclusion: TIPU has the advantage of shorter operating time but a higher incidence of meatal stenosis than DIGU.

Analysis of The Curative Effect of Tubularized Incised Plate Urethroplasty for Distal Hypospadias With The Dysplastic Corpus Spongiosum Covering Technique.

To investigate the use of tubularized incised plate (TIP) urethroplasty for distal second- and third-degree hypospadias to free the dysplastic forked corpus spongiosum and Buck's fascia, which are used as a covering material for the new urethra, thereby reducing the incidence of urinary fistula and other complications in the coronal sulcus. Clinical data of 113 patients with distal hypospadias treated with TIP urethroplasty from January 2017 to December 2020 were retrospectively analyzed. The study group comprised 58 patients (use of dysplastic corpus spongiosum and Buck's fascia to cover the new urethra), and the control group comprised 55 patients (use of dorsal Dartos fascia to cover the new urethra). All children were followed up for more than 12 months. In the study group, 4 patients developed urinary fistulas, 4 developed a urethral stricture, and no case developed glans fissure. In the control group, 11 patients developed urinary fistulas, 2 developed a urethral stricture, 3 developed a glans cracking. Using the dysplastic corpus spongiosum to cover the new urethra increases the amount of tissue in the coronal sulcus and reduces the incidence of urethral fistula, but it may increase the incidence of urethral stricture.

Surgical Technique of Glans Wings Creation with Preservation of Glanular Vascular Arcade and Creating Flaps for Tension-Free Glansplasty in Hypospadias Repair.

The objective of this study is to report the technical nuances of glans wings creation in anatomical plane facilitating liberal glans wings mobilization with preservation of glanular vessels for tension-free glansplasty in surgery of hypospadias in primary and redo cases. Eighty-six primary hyposapdias and 7 cases of distal hypospadias, operated elsewhere and presented with glans and urethroplasty dehiscence, undergoing tubularized-incised-plate (TIP) repair were included after ethical approval. Technical points of glans wings creation in the subfascial plane included (i) creation of Buck's fascia window, just proximal and lateral to the point of bifurcation of corpus spongiosum, (ii) creation of subfascial-pret unical plane on the tunica albuginea of corpora cavernosa up to ventral limit of laid open glanular meatus, (iii) release of pillars of corpus spongiosum off the glans base keeping the basal lamina propria covering the vascular arcade intact, (iv) release of glans base off the tip of corpora cavernosa and composite flap of corpus spongiosum pillars with Buck's fascia off the corpora cavernosa, (v) approximation of glans wings over the tubularized-incised-plate covered with dartos, and (vi) approximation of fasciospongioplasty flaps at hypospadiac meatus. Outcome measurement included (i) intra and postoperative problems and (ii) elimination of glans dehiscence. There occurred 1 injury to the tunica albuginea of ventral corpora cavernosa and 1 button-hole injury to subcoronal mucosal collars. Flaps for fasciospongioplasty were short in 11. One glans dehiscence occurred in flat glans. This technique is effective in creating glans wings in the anatomical plane with the preservation of glanular vessels and flaps for fasciospongioplasty eliminating the possibility of glans dehiscence in both fresh and redo cases.

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.

Postoperative complications of Mathieu incised plate versus standard tubularized incised plate urethroplasty for distal hypospadias: a systematic review and meta-analysis

Introduction: Surgical reconstruction is the mainstay treatment for distal hypospadias. A range of urethroplasty techniques is available with their benefits and disadvantages. We conducted a study to investigate the postoperative complications of Mathieu with plate incision technique relative to standard tubularized incised plate (TIP) technique in patients with distal hypospadias. Materials and Methods: The course of the study was referred to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Designated articles were clinical trials comparing postoperative complications of Mathieu with plate incision and standard TIP technique for distal hypospadias, systematically searched through PubMed and ScienceDirect databases. Pooled studies were analyzed in qualitative and quantitative methods. The protocol of this study was registered on PROSPERO (CRD42022341745). Results: Meta-analysis of the included studies yielded a significant difference in the postoperative incidence of meatal stenosis, narrow stream, and fistula formation of distal hypospadias patients in favor of Mathieu with plate incision compared to standard TIP technique, with Mantel-Haenszel test result of OR: 0.08 CI 0.01-0.41 (p = 0.003) for meatal stenosis; OR: 0.09 CI 0.02-0.49 (p = 0.006) for narrow stream; and OR: 0.28 CI 0.08-0.96 (p = 0.04) for fistula formation. All outcomes presented insignificant heterogeneity across studies (p &gt; 0.05). Conclusion: The incidence of meatal stenosis, narrow stream, and fistula formation is lower in patients with distal hypospadias who underwent Mathieu with plate incision procedure than the standard TIP urethroplasty.

Complications of Tubularized Incised-Plate (TIP) Urethroplasty in Anterior Hypospadias Repair: Interrupted VS Continuous Suture

Introduction: Hypospadias is a congenital defect that affects the development of the urethra in males, causing the urethral opening to be located on the underside of the penis rather than at the tip. Repair of hypospadias is a surgical procedure that aims to create a normal-appearing and functional penis that allows for normal urination. The tubularized incised-plate (TIP) technique is a widely used surgical approach for correcting distal hypospadias. TIP urethroplasty can be performed using either continuous or interrupted suture techniques. The present study aims to compare the complications of these two techniques in TIP urethroplasty for the repair of hypospadias. Aim of the Study: The aim of the study was to compare the complication rate among continuous and interrupted suture in TIP urethroplasty for anterior hypospadias repair. Methods: This Prospective Randomized comparative study was conducted at the Department of Pediatric Surgery, Bangladesh Shishu Hospital &amp; Institute, Dhaka, Bangladesh. The study duration was 5 years, from July 2017 to June 2022. After some drop-out patients, a total of 68 patients had been left, with Group-1 having 35 continuous suture TIP urethroplasty, and Group-2 having 33 interrupted sutures TIP urethroplasty. Result: The mean age of participants was 41.15±24.46 months in Group-1 and 38.05±25.14 months in Group-2. The mean weight of participants was 17.79±6.37 kg and 19.14±9.19 kg in Group-1 and Group-2 respectively. Operation time in group 1 and group 2 was 66.86±3.51 minutes and 79.38±5.04 minutes respectively, with statistically significant difference. But none of the post-operative complications had significant difference between the groups. Conclusion: The study showed that although operative time was significantly lower among patients undergoing continuous suture for TIP urethroplasty instead of interrupted suture TIP urethroplasty, the overall complications rate had no significant difference between the groups.

Identifying variability in surgical practices and instrumentation for hypospadias repair across the Western Pediatric Urology Consortium (WPUC) network

Although hypospadias outcomes studies typically report a level or type of repair performed, these studies often lack applicability to each surgical practice due to technical variability that is not fully delineated. An example is the tubularized incised plate (TIP) urethroplasty procedure, for which modifications have been associated with significantly decreased complication rates in single center series. However, many studies fail to report specificity in techniques utilized, thereby limiting comparison between series. With the goal of developing a surgical atlas of hypospadias repair techniques, this study examined 1) current techniques used by surgeons in our network for recording operative notes and 2) operative technical details by surgeon for two common procedures, tubularized incised plate (TIP) distal and proximal hypospadias repairs across a multi-institutional surgical network. A two-part study was completed. First, a survey was distributed to the network to assess surgeon volume and methods of recording hypospadias repair operative notes. Subsequently, an operative template or a representative de-identified operative note describing a TIP and/or proximal repair with urethroplasty was obtained from participating surgeons. Each was analyzed by at least two individuals for natural language that signified specified portions of the procedure. Procedural details from each note were tabulated and confirmed with each surgeon, clarifying that the recorded findings reflected their current practice techniques and instrumentation. Twenty-five surgeons from 12 institutions completed the survey. The number of primary distal hypospadias repairs performed per surgeon in the past year ranged from 1-10 to >50, with 40% performing 1-20. Primary proximal hypospadias repairs performed in the past year ranged from 1-30, with 60% performing 1-10. 96% of surgeons maintain operative notes within an electronic health record. Of these, 66.7% edited a template as their primary method of note entry; 76.5% of these surgeons reported that the template captures their operative techniques very or moderately well. Operative notes or templates from 16 surgeons at 10 institutions were analyzed. In 7 proximal and 14 distal repairs, parameters for chordee correction, urethroplasty suture selection and technique, tissue utilized, and catheter selection varied widely across surgeons. Wide variability in technical surgical details of categorically similar hypospadias repairs was demonstrated across a large surgical network. Surgeon-specific modifications of commonly described procedures are common, and further evaluation of short- and long-term outcomes accounting for these technical variations is needed to determine their relative influence.
