Multi-Institutional Analysis of Surgery for Lichen Sclerosus-Induced Penile Urethral Stricture: Establishing Single-Stage Urethroplasty as a Primary Treatment Option.

Ideal treatment of lichen sclerosus (LS)-induced penile urethral strictures (PUS) remains elusive. The objective of this study was to compare multi-institutional outcomes of single-stage urethroplasty (SSU) with oral mucosal graft, staged urethroplasty, and perineal urethrostomy (PU) for treatment of LS-induced PUS. Multi-institutional analysis was performed at 9 centers on men undergoing SSU, staged urethroplasty, or PU for LS-induced PUS. Meatal strictures (<2 cm), bulbar urethral involvement, and panurethral strictures (>10 cm) were excluded. The primary outcome was recurrence-free status on follow-up assessment. Secondary outcomes included 90-day complications (Clavien ≥ 2), erectile dysfunction, chordee, and urethrocutaneous fistula. Two hundred thirty-one patients were included with a median stricture length of 5 cm and median follow-up of 53 months among those without stricture recurrence. 1-, 5-, and 10-year stricture-free estimates were 90%, 80%, and 75%, respectively. 55% (127/231) underwent SSU with oral mucosal graft, 19% (44) staged urethroplasty, and 26% (60) underwent PU. On log-rank, there was no identifiable difference in stricture recurrence between techniques (P = .6) with 5-year stricture-free estimates of 82%, 76%, and 75%, respectively. On χ2, there was no significant difference in 90-day complications (7.1% vs 16% vs 8.3%; P = .2), erectile dysfunction (7.1% vs 4.5% vs 3.3%; P = .6), chordee (5.5% vs 6.8% vs 1.7%; P = .4), or urethrocutaneous fistula (2.4% vs 6.8% vs 0%; P = .09). On Cox regression, only obesity (BMI ≥ 35) was associated with stricture recurrence (HR, 2.31, 95% CI, 1.28-4.17; P = .006). Favorable comparative outcomes confirm SSU as a highly feasible treatment for LS-induced PUS in properly selected patients, especially when considering fewer surgeries required and preservation of an orthotopic meatus.

Surgical and patient-reported outcomes of staged urethroplasty for anterior urethral strictures: A comprehensive analysis.

To evaluate the efficacy of staged urethroplasty for complex anterior urethral strictures from both surgical and patient-reported outcome perspectives. This retrospective study included 100 patients who underwent staged urethroplasty for anterior urethral strictures between May 2011 and June 2023. Anatomical success was defined as the ability to pass cystourethroscopy without resistance and the patient's ability to void without additional interventions. Patient-reported outcomes were evaluated using validated questionnaires, including the urethral stricture surgery patient-reported outcome measure, sexual health inventory for men (SHIM), and EuroQol 5-dimension (EQ-5D), administered pre-and postoperatively. At a median follow-up of 53 months, the anatomical success rate was 89.0%. Seventeen (17.0%) required revision surgery between stages. Perioperative complications occurred in 13 (13.0%). Significant improvements were observed in maximum flow rate (p < 0.0001), postvoid residual volume (p = 0.0006), total lower urinary tract symptoms (LUTS) scores (p < 0.0001), LUTS-specific quality of life (QOL) score (p < 0.0001), EQ-5D index score (p < 0.0001), and EQ-5D visual analog scale score (p < 0.0001). SHIM scores showed no significant change (p = 0.59). Overall, 93.5% of patients reported being either "satisfied" or "very satisfied" with the outcomes. Staged urethroplasty demonstrates high anatomical success rates and significant improvements in urinary function and QOL without compromising erectile function. The high patient satisfaction rate supports its efficacy in treating complex anterior urethral strictures.

Changes in practices concerning urethral stricture surgery: Analysis of French data for the period 2013–2022

IntroductionThe prevalence of urethral stricture is estimated at 0.9%. American, European and French recommendations have reduced the place of endoscopic treatments due to their poor outcomes, especially in the case of repeated procedures. Urethroplasty is the new reference treatment for urethral stricture. Our aim was to assess the evolution of national practices from 2013 to 2022. Material and methodsWe collected national CCAM coding data for all procedures involving urethral stricture surgery using the Scansanté internet platform produced by the Technical Agency for Information on Hospitalization, which prospectively collects all procedures coded according to CCAM coding from public, liberal and ESPIC healthcare structures. ResultsThe overall number of urethral surgical procedures has been steadily increasing over the past 10 years. Endoscopic procedures remain largely predominant in 2022, totaling 23,982, but have remained stable over the decade. Urethroplasties have been on the rise since 2019, reaching 1600 cases in 2022 compared with 1100 cases in 2020. Although urethrotomies currently outnumber urethroplasties by a factor of 10, this ratio has been consistently decreasing since 2016. The most significant contributor to the 10-year increase is urethroplasty by augmentation, particularly free flap techniques on the anterior urethra. Resection-anastomosis and urethrostomy techniques have remained stable. DiscussionIn 2022, endoscopic treatments remain by far the majority, but urethroplasties are on the increase. A significant number of patients can benefit from initial endoscopic treatment because short bulbar localization is the most common presentation, but long-term success rates are poor compared to urethroplasty, which boasts approximately 80% success rates. Urethroplasty should no longer be considered a last-resort surgery but rather a reference technique in treating urethral stricture. Level of evidence4.

The use of amniotic membrane injection as an adjunct in endoscopic urethral stricture management.

Endoscopic urethral stricture treatment has high recurrence rates. Due to research supporting amniotic membrane's (AMs) anti-inflammatory and anti-fibrotic properties reducing scar tissue formation, AM has generated interest in reconstructive urethral surgery. To the best of our knowledge, we performed the first investigation of the success rate of urethral dilation when combined with micronized AM injection for the treatment of urethral stricture. Eligible patients were adult males with anterior strictures meeting strict criteria for diameter, length, International Prostate Symptom Score (IPSS), and flow rate. Micronized AM was injected in the stricture region during urethral dilation. The primary study endpoint was an anatomical success (≥14Fr) at 6 months. Secondary endpoints were evaluated with the IPSS, urethral stricture surgery - patient-related outcome measure, International Index of Erectile Function, flow rate, and postvoid residual. Outcomes were assessed at baseline and multiple points postinjection. Injection safety was analyzed. Ten men with a mean age of 52 years were included in the study. At 6 months, 7 of 10 patients demonstrated recurrence of the urethral stricture on cystoscopy. Improvements in secondary endpoints were noted in 10 of 10 patients at 3 months and 3 of 10 patients at 6 months. No adverse events were observed. To the best of our knowledge, this is the first study evaluating micronized AM injection as an adjunct treatment at the time of urethral dilation. The urethral stricture recurrence rate did not improve with the injection of AM despite the hypothesized benefits of anti-fibrotic and anti-inflammatory properties.

Functional outcomes after supra-pubic phalloplasty

BACKGROUNDA thorough evaluation of the functional outcomes resulting from supra-pubic phalloplasty (SPP) assessing different aspects of the phalloplasty has not been reported. PURPOSE OF THE STUDYTo report the outcomes on sexuality, urinary function, satisfaction, and regrets following an SPP performed at our centre. SUBJECTS STUDIEDAll consecutive patients who underwent the 3-steps technique of pre-expanded SPP between 2007 and 2018 and who had at least 1 year of follow-up. METHODSQuestionnaires were sent to analyse several domains of penile reconstruction: sexuality, urinary function, perceived sensitivity, and satisfaction. Sexuality was evaluated using the Self Esteem and Relationship (SEAR) questionnaire. Urinary function was analysed based on the urethral stricture surgery PROM (USS-PROM) questionnaire. MAIN FINDINGSA total of 77 patients were included, 92.2% were transmen, and 33 (42.9%) responded to the questionnaire. Urethral lengthening (UL) was performed in 28 (36.4%) procedures and erectile prosthesis was implanted in 42 patients (54.5%). The mean length of the neophallus was 15.3cm (SD 2.6) and the mean girth was 11.8cm (SD 2.1). The mean total SEAR score (/100) was 73.8 (SD 26.7). The mean six-item LUTS score (/24) was 8.4 (SD 4.6). The standing position was the usual voiding position reported by 11 patients (73.3%). CONCLUSIONPre-expanded SPP is a robust technique that can achieve substantial flap dimensions, leading to high satisfaction with neophallus appearance and the choice of the phalloplasty technique. Overall sexual outcomes are mostly favourable. UL is feasible and effective in terms of voiding in a standing position.

Artificial urinary sphincter and stricture disease: surgical principles in management.

Iatrogenic stress urinary incontinence (SUI) is the most common complication of surgical treatment of prostate cancer, regardless of operative approach, and has a major impact on patients' quality of life. Although SUI can occur after surgical treatment of benign prostatic hyperplasia, specifically transurethral prostate resection, laser enucleation of the prostate, and simple open prostatectomy, these therapeutic modalities play a much less significant role in the etiology of SUI. Artificial urethral sphincter (AUS) implantation is considered the standard treatment modality providing high success rates, including durable efficacy, and optimal patient satisfaction for moderate to severe urinary incontinence resulting mainly from radical prostatectomy. However, although complication rates are generally acceptably low, revision and/or explantation may be required due to mechanical failure and non-mechanical problems, specifically urethral atrophy/cuff deficient occlusion, infection, and cuff erosion. Several risk factors for AUS failure associated with a fragile, compromised urethra have been identified and these play a critical role in device cuff erosion and subsequent removal of the device. Among others, apparently the most impacting factors are irradiation, urethral stent placement, a previous AUS placement, and importantly presence of urethral stricture or prior urethroplasty. Generally, any clinical situation leading to a diseased urethra or lack of urethral integrity is associated with impaired local blood perfusion, and consequently lower success rates. The present review aims to evaluate the impact of the presence of prior urethral strictures and urethroplasty on the outcomes of AUS implantation on one hand, and vice-versa, the influence of AUS placement on later urethral stricture surgery, particularly following cuff erosion.

Perineal Urethrostomy for Complex Urethral Strictures: Long-Term Patient-Reported Outcomes From a Reconstructive Referral Center and a Scoping Literature Review.

There is a paucity of long-term objective and patient-reported outcomes after definitive perineal urethrostomy for complex urethral strictures. Our objective is to determine comprehensive long-term success of perineal urethrostomy with our 15-year experience at a reconstructive referral center. Patients who underwent perineal urethrostomy between 2009 and 2023 were identified. A comprehensive long-term follow-up was conducted, evaluating both objective outcomes (retreatment-free survival) and subjective outcomes through the use of validated questionnaires. Additionally, to provide further context for our findings, we conducted a scoping review of all studies reporting outcomes following perineal urethrostomy. Among 76 patients, 55% had iatrogenic strictures, with 82% previously undergoing urethral interventions. At a median follow-up of 55 months, retreatment-free survival was 84%, with 16% of patients experiencing perineal urethrostomy recurrent stenosis. Patient-reported outcomes revealed a generally satisfactory voiding function (Urethral Stricture Surgery Patient-Reported Outcome Measure Lower Urinary Tract Symptoms score) and continence (International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form), with median scores of 4 (range 0-24) and 0 (range 0-21), but with bimodal distributions of sexual function scores (median International Index of Erectile Function-Erectile Function domain: 3.5; median Male Sexual Health Questionnaire-Ejaculation Scale: 21). Treatment satisfaction was very high with a median International Consultation on Incontinence Questionnaire-Satisfaction outcome score of 21 (range 0-24). The scoping review revealed varying success rates ranging from 51% to 95%, highlighting difficulties in comparison due to variable success definitions and patient case mix. Perineal urethrostomy provides effective treatment for complex anterior urethral strictures, with high patient satisfaction, preserved continence function, and favorable voiding outcomes. It presents a viable option for older and comorbid patients, especially after thorough counseling on expected outcomes and potential risks.

DIFFERENTIATED VULVAR INTRAEPITHELIAL NEOPLASIA: A CLINICAL EXAMPLE OF INTERDISCIPLINARY PATIENT MANAGEMENT

Differentiated vulvar intraepithelial neoplasia (dVIN) is an obligate precancer, develops during chronic vulvodermatoses, such as lichen sclerosus and lichen simplex chronicus. The epidemiological, clinical, pathomorphological, diagnostic, and prognostic features of dVIN are discusses. A clinical case of interdisciplinary management of a patient with dVIN, complicated by malignancy and urethral stricture, is presented. Early oncological alertness was demonstrated, microinvasive vulvar cancer in woman with of lichen sclerosus was diagnosed. It is actually, because there is high amount primary patients with advanced vulvar cancer. The joint work of oncologists, urologists, and gynecologists made it possible to successfully perform reconstructive plastic surgery for urethral stricture using a buccal graft for the first time in the Trans-Baikal Territory. Thanks to this the urinary function was restored and the quality of life improved.

Urethral-sparing laparoscopic simple prostatectomy for the treatment of benign prostatic hyperplasia with asymptomatic urethral stricture after urethral stricture surgery

ObjectiveTo evaluate the efficacy of urethral-sparing laparoscopic simple prostatectomy (US-LSP) for the treatment of large-volume (>80 ml) benign prostatic hyperplasia (BPH) with asymptomatic urethral stricture (urethral lumen > 16 Fr) after urethral stricture surgery.MethodsWe retrospectively analyzed clinical data of 39 large-volume BPH patients with asymptomatic urethral stricture after urethral stricture surgery who underwent US-LSP from January 2016 to October 2021. Postoperative follow-ups were scheduled at 1, 3, and 6 months.ResultsAll patients affected by significant BPH-related lower urinary tract symptoms (LUTS) including 22 cases with asymptomatic anterior urethral stricture and 17 cases with asymptomatic posterior urethral stricture. Median operative time was 118 min (interquartile range [IQR]100–145). Median estimated blood loss was 224 ml (IQR: 190–255). 33 patients(84.6%) avoided continuous bladder irrigation. Postoperative complications occurred in 5 patients (12.8%), including 4 cases with Clavien-Dindo grade 1 and grade 2 and 1 case with grade 3a. During follow-up, US-LSP presented statistically significant improvements in LUTS compared to baseline (P < 0.05). A total of 25 patients had normal ejaculation preoperatively and 3 patients (12%) complained retrograde ejaculation postoperatively. Two patients (5.1%) reported stress urinary incontinence (SUI) and no patient reported aggravated urethral stricture during follow-up.ConclusionsUS-LSP was safe and effective in treating large-volume BPH with asymptomatic urethral stricture after urethral stricture surgery. Meanwhile, US-LSP could reduce the risk of SUI in patients with asymptomatic posterior urethral stricture and maintain ejaculatory function in a high percentage of patients.

Comparative analysis of holmium: YAG laser internal urethrotomy versus Cold-Knife optical internal urethrotomy in the management of urethral stricture - a systematic review and meta-analysis.

Urethral stricture management has posed enduring challenges in urology, demanding innovative and effective treatment modalities. This study addresses the persistent issues associated with urethral strictures, focusing on the comparative evaluation of two contemporary treatment modalities: Ho: YAG Laser Internal Urethrotomy (HIU) and Cold Knife Optical Internal Urethrotomy (CIU). A comprehensive search of PubMed, Embase, Web of Science, Cochrane Library, and ResearchGate was conducted to identify relevant studies up to November 2023. Inclusion criteria encompassed comparative studies evaluating HIU and CIU in patients with urethral stricture. Data extraction, quality assessment, and subgroup analyses were performed using standardized methods. Outcome measures included preoperative and postoperative mean the maximum urine flow rate (Qmax), mean surgical time, recurrence rates, and perioperative complications. Nine articles met the inclusion criteria, and their data were analyzed using RevMan 5.4.1. Forest plots were generated for preoperative and postoperative mean Qmax, mean surgical time, recurrence rates, and perioperative complications. While postoperative mean Qmax (MD -0.06; 95% CI: -0.28-0.16; P =0.60, I2 =75%) and mean surgical time (MD 2.16; 95% CI: -1.66-5.99; P =0.27, I2 =98%) showed no significant differences between HIU and CIU, a trend towards lower recurrence rates (RR 0.71; 95% CI: 0.48-1.06; P =0.09, I2 =46%) was observed with HIU but without statistical significance. Perioperative complications, particularly bleeding (RR 0.21; 95% CI: 0.08-0.53; P =0.001, I2 =0%), favored HIU over CIU. The subanalysis indicates that for the treatment of complex urethral strictures, the two surgical methods differ in terms of mean Qmax at 6 months postoperatively (MD -2.51; 95% CI: -4.10--0.91; P =0.002, I2 =59%) and 12 months postoperatively (MD 2.62; 95% CI: 0.93-4.30; P =0.002, I2 =0%). The HIU group shows a significant decrease in recurrence rate at 12 months postoperatively (RR 0.44; 95% CI: 0.21-0.92; P =0.03, I2 =0%). For short-segment urethral strictures with a length ≤1.5cm, CIU had a shorter operative time compared to the HIU (MD 4.49; 95% CI: 3.87-5.10; P <0.00001, I2 =44%). Overall, both interventions demonstrated similar efficacy in improving postoperative mean Qmax, mean surgical time, and recurrence rates. However, subanalysis indicates that in the short-term, CIU is more effective than HIU in improving Qmax after complex urethral stricture surgery. In long-term Qmax follow-up after surgery, HIU is significantly higher than CIU, and HIU has a low recurrence rate. In addition, for short-segment urethral stricture (≤1.5cm), CIU requires less time. In terms of complications, HIU has a lower risk of bleeding.

Long-term Results of Optical Laser Urethrotomy for Post-traumatic Stricture of the Membranous Urethra

Urethral stricture is a common condition characterized by the narrowing of the urethra, leading to difficulty in urination. This article presents a case report of a 47-yearold male with urethral stricture following a pelvic fracture. The patient presented with urinary retention and a history of traumatic injury. Diagnostic imaging revealed a 2.0-2.2 cm stricture in the membranous urethra. Surgical intervention, including optical laser urethrotomy and silicone urethral catheter placement, was performed successfully. Postoperative management included antibacterial and anti-inflammatory therapy, leading to the restoration of independent urination. Urodynamic examination confirmed the successful outcome of the surgery. This case demonstrates that endoscopic surgery for urethral strictures can have a favorable prognosis. However, due to the potential for recurrence, ongoing outpatient care and monitoring by a urologist are essential for these patients.

Brazilian portuguese validation of the patient-reported outcome measure for urethral stricture surgery (USS-PROM) questionnaire.

Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria. The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee. This pre-version was administered to 10 patients who had undergone urethroplasty by the Reconstructive Urology team at the Hospital de Clínicas de Porto Alegre for face validation, linguistic, and semantic adjustments, resulting in the final USS-PROMbr version. Subsequently, well-established psychometric criteria, including content validity, internal consistency, and test-retest reproducibility, were assessed after administering the questionnaire to a total of 56 patients, with 50 of them responding to the test and retest. Evaluation of the pre-final version identified 15 questions as clear, and only one question was considered somewhat unclear necessitating modifications based on patient suggestions and subsequent reassessment by the research team. Psychometric criteria demonstrated good content validity, with a content validity index exceeding 0.80 for all questions; good internal consistency, Cronbach's alpha of 0.77, ranging from 0.70 to 0.78 with the exclusion of any item, and item-total correlations ranging from 0.33 to 0.67. The test-retest intraclass correlation coefficient was 0.74 for the lower urinary tract symptoms construct (Q1-Q6). The USS-PROMbr demonstrated acceptable cross-cultural adaptation and psychometric properties, making it a valid and useful tool for evaluating patients undergoing urethroplasty.

Surgery for female urethral stricture.

Female urethral stricture (FUS) is a rare entity that causes great morbidity and suffering in those affected. As the available scientific data is sparce, there are no formal guidelines or standard of care for this disease. This is a narrative review of the surgical management for female urethral stricture. The literature review was performed on PubMed. Articles were limited to English, but there was no limitation in terms of date. Management of FUS is divided between endoscopic and open surgical repair. Urethral dilation with or without urethrectomy can be offered as a first-line treatment. However, the rate of success of this procedure remains inferior to open surgical repair, and its efficacy decreases with the number of previous dilations. For distal urethral strictures, distal urethrectomy and advancement meatoplasty may be considered. Vaginal flaps are readily available, easy to harvest, well-vascularized, and allow for a dorsal or ventral orientation urethroplasty. The results of this procedure are promising, but most studies are small and retrospective. Labia flaps are easily accessible, wet, hairless, and elastic. The main limitations with the use of vaginal or labial tissues are co-existing conditions such as lichen sclerosis or vaginal atrophy, which may affect future results. Vaginal and labial graft urethroplasty can be used when it is not possible to mobilize an adequate flap. Stricture-free rates of this technique are variable. In cases of more severe stricture, an augmentation urethroplasty using buccal mucosa graft may be necessary. The techniques used in FUS replicate those for male urethral strictures, where both ventral and dorsal approaches can be utilized. Although there is growing interest in the field, the optimal management of FUS remains to be determined.

Patient-Reported Outcome Measures Using Modified Urethral Stricture Surgery: Patient-Reported Outcome Measure for Direct Visual Internal Urethrotomy and Nontransecting Urethroplasty for Short Nontraumatic Bulbar Urethral Stricture – A Prospective Comparative Observational Study from a University Teaching Hospital

Purpose: To evaluate the patient-reported outcomes of primary direct visual internal urethrotomy (DVIU) and nontransecting bulbar urethroplasty techniques (NTBU) for the short segment (&lt;2 cm) nontraumatic bulbar urethral stricture using the modified urethral stricture surgery patient-reported outcome measures (USS PROMs). Materials and Methods: The USS PROM questionnaire used to evaluate lower urinary tract symptom (LUTS) was modified by adding a six-item International Index of Erectile Function and a four-item version of MSHQ-EjD to evaluate erectile and ejaculatory domains. All cases of short nontraumatic bulbar urethral stricture who underwent primary DVIU and NTBU who consented were asked to fill the modified PROM at initial evaluation, at 6 months, and at 1 year. Results: The LUTS score for NTBU at 12 months is significantly better (1.93 ± 2.13 vs. 8.76 ± 5.92, P = 0.000). The Peeling score of the NTBU is significantly better at 12 months (1.41 ± 0.68 vs. 2.67 ± 0.73, P = 0.000). The erectile function score at 12 months for NTBU is better than DVIU (24.37 ± 3.2 vs. 21.143 ± 2.86, P = 0.001). The Ejaculatory function score at 6 months and 12 months is significantly better for the NTBU. Receiver operating characteristic (ROC) AND Odd's Ratio analysis for analyzing patient satisfaction showed erectile function (area under ROC [AUROC] - 0.889, P &lt; 0.001), ejaculatory function (AUROC - 0.957, P &lt; 0.001) at 1 year and maximum flow rate of urine on uroflometry (Qmax) (AUROC - 0.928, P &lt; 0.001) at 6 months and (AUROC - 1.000, P &lt; 0.001) at 1 year. The overall satisfaction rates in patients undergoing NTBU is 96.5%. Conclusion: NTBU shows superior outcomes in almost all domains of USS-PROM with better overall satisfaction rates. Improvement of sexual function domain, followed by the LUTS domain was the best predictor of overall patient satisfaction and improvement in the quality of life at 1 year.

Fast Track Surgery as the Latest Multimodal Strategy of Enhanced Recovery after Urethroplasty.

Fast track surgery (FTS), as well as ERAS (enhanced recovery after surgery/rapid recovery programs), is the latest multimodal treatment strategy, designed to reduce the disability period and improve the medical care quality. The study aims to analyze the enhanced recovery protocol effectiveness in a comparative study of elective urethral stricture surgery. A prospective study included 54 patients with an established diagnosis of urethral stricture in 2019-2020 in the urological hospital of the Irkutsk City Clinical Hospital No. 1. All 54 patients have completed the study. There were two groups of patients FTS-group (group II, n = 25) and standard group (group I, n = 29). In terms of preoperative parameters, the comparison groups have statistical homogeneity. The comparative intergroup efficacy analysis of the treatment based on the criteria established in the study demonstrated good treatment results for 5 (17.2%) patients of group I and 20 (80%) patients of group II (p=0.004). The overall efficacy of urethroplasty surgeries, regardless of the treatment protocol, was comparable (86.2% vs 92%; p=0.870), as well as the likelihood of relapse within two years (p=0.512). The predictors of recurrence were technical complications and urethral suture failure (OR 4.36; 95% CI 1.6; 7.11; p=0.002). The FTS protocol reduced the treatment period (p < 0.001) and decreased the severity of postoperative pain (p < 0.001). The use of the "fast track surgery" protocol in urethroplasty with generally similar treatment results makes it possible to achieve a better functional and objective condition of patients in the postoperative period due to less pain, shorter catheterization, and hospitalization.

Urethral Stricture and Methods for its Correction

A stricture is a type of narrowing of the urethra, which can be caused by a variety of reasons. In addition, urethral strictures are associated with a wide range of symptoms and require special diagnostic examination before proceeding with any treatment. The treatment of urethral strictures has remained a challenge for many years. Stricture recurrence is still a serious problem in reconstructive urology. During the second half of the 20th century, urologists tried to find solutions for treating both simple and complex urethral strictures. Within the last few decades research has mainly focused on improving existing procedures to mitigate the negative postoperative effects. Despite considerable scientific achievements in this area, numerous studies have revealed a lack of knowledge about urethral stricture surgery among urologists and have shown that patients with urethral strictures are generally offered inadequate treatment options. Currently, many surgical interventions are available to treat this condition. However, the variety of treatment methods reflects a lack of optimal technique. This bibliographical review presents data on the effectiveness of minimally invasive (endoscopic) and various urethroplasty options in urological practice.

Outcomes of HUD Versus CIC in Patients With Urethral Strictures.

Treatment of urethral stricture is a complex reconstructive urology treatment. Previous surgery in the treatment of urethral stricture increases the risk of urinary incontinence. Therefore, this study aimed to assess the outcome of comparing two preservative or nonsurgical methods, clean intermittent catheterization (CIC) or hydraulic urethral dilatation (HUD). Forty-eight patients diagnosed with symptomatic urethral stricture were enrolled in the study. Patients were randomly divided into two groups: Nelaton-based dilatation and HUD treatment. Patients were assessed using patient-reported outcome measure for urethral stricture surgery (USS-PROM) through direct clinical interview and were followed up for 12 months. The rate of urinary infection, the need for surgical intervention, and the patient's quality of life were considered as outcomes of the interventions. SPSS software, version 20.0, was used for statistical analysis. Overall, 23 (47.9%) patients underwent HUD of stricture and Nelaton-based dilatation of stricture was done in 25 (52.1%) patients. We found that surgical intervention was required in four patients in the HUD group, but 15 patients in the CIC group required surgical intervention. Also, the need for surgical intervention and urinary tract infection (UTI) was significantly greater in the CIC group compared with the HUD group. With respect to the patient-reported outcomes, the mean Peeling's voiding picture (Q8) and EQ-VAS score (Q16) in the HUD group (p = .02) were significantly greater than those in the CIC group (p = .02). We obtained excellent results by using an HUD catheter. This safe, simple, well-tolerated, home-based procedure reduced the need for hospital admission to operate for repeat.

Multi-stage surgery for anterior urethral strictures: assessment of immediate and long-term surgical outcomes

BACKGROUND: The progress made in reconstructive urethral surgery over the past 20 years has shown the effectiveness of one-stage repair of anterior urethral strictures. Nevertheless, multi-stage urethroplasty retains its primary role in the treatment of patients with the most complex urethral narrowing and obliterations.&#x0D; AIM: To evaluate the immediate and long-term surgical results of multi-stage urethroplasty for penile and bulbar urethral strictures.&#x0D; MATERIALS AND METHODS: The study included 110 men aged 1884 years who underwent multi-stage urethroplasty for the anterior urethral structures in 20102019. The techniques of buccal and skin augmentation or urethral replacement plastics were applied. Before surgery, all patients underwent a standard urological examination. Early surgical complications were evaluated from medical records. Late surgical complications were determined according to examinations that included symptomatic assessment with specialized questionnaires, laboratory tests of serum and urine, physical examination, uroflowmetry, and retrograde urethrography and ureteroscopy (if urinary disorders were detected). The median follow-up was 5 years and 2 months.&#x0D; RESULTS: Early surgical complications were detected in 27 (24.5%) patients. Surgical interventions to resolve them were required in 7 (31.8%) cases: urethrocutaneous fistulas (5), acute urinary retention (1), scrotal hematoma (1). Late surgical complications were detected in 33 (30.0%) patients, including 29 (26.7%) cases of recurrent urethral strictures. All late complications cases were classified as Clavien-Dindo IIIb, and a total of 49 additional operations were performed to eliminate them. The primary success rate for multi-stage urethroplasty was 67.3 % with a median follow-up of 62 months. Only 73 (66.4%) completed all stages of the planned surgery. Urethral integrity throughout its entire length was restored in 67 (60.9%) cases, spontaneous urination in 106 (96.4%) cases.&#x0D; CONCLUSIONS: Multi-stage surgery for anterior urethral strictures is associated with relatively high risks of surgical complications at each stage of treatment. The probability of surgical revision of complications can reach 31.8%. Patients should be informed about the risks of developing surgical complications and the potential for more than two surgeries to achieve treatment goals when planning multi-stage urethroplasty.

Multi-stage urethroplasy for anterior urethral strictures: objective parameters of long-term efficacy and patient-reported outcomes

Introduction. Multi-stage urethral surgery is used in cases of the most complex urethral strictures. The evaluation of surgical treatment results given by patients is a significant criterion for the efficacy of urethroplasty along with the assessment of urethral patency through instrumental examinations.Objective. To evaluate the long-term efficacy of multistage urethroplasty for complex anterior urethral strictures considering the patients' quality of life and satisfaction with the surgical outcomes.Materials and methods. The study included 73 patients aged 18 – 84 years with anterior urethral strictures who underwent multi-stage urethroplasty in 2010 – 2019. Surgical and functional outcomes of urethroplasty were assessed through general blood and urine tests, physical examination, uroflowmetry, and retrograde urethrography and urethroscopy in case of urinary disorders. Subjective parameters of treatment efficacy were studied using questionnaires: International Prostate Symptom Score (IPSS); Quality of life (QoL); Patient-reported Outcome Measure for Urethral Stricture Surgery (USS-PROM); Patient Global Impression of Improvement (PGI-I).Results. Recurrent urethral stricture was detected in 19 (26,0%) patients with the average follow-up period being 65 months. Independent urination was restored in 71 (97.3%) cases, including repeated interventions. After surgery, there was a significant increase in urinary flow rate parameters (Q max: 8.1 vs 19.1 ml/s, p &lt; 0.0001; Q ave: 5.5 vs 10.7 ml/s; p = 0.0004), decrease in residual urine volume (62.4 vs 18.6 ml, p &lt; 0.0001), decrease in total IPSS score (18.7 vs 5.7 points; p &lt; 0.0001) and QoL index (4.3 vs 1 .8 points, p &lt; 0.0001). A comparative analysis of preoperative and postoperative USS-PROM questionnaire results demonstrated an improvement in indicators assessing LUTS (12.9 vs 3.4 points; p &lt; 0.0001; 3.6 vs 1.7 points; p &lt; 0.0001), and urination-associated quality of life (2.6 vs 0.6 points; p &lt; 0.0001) and overall health (EQ-5D index: 0.73 vs 0.91 points; p = 0.025; EQ-VAS: 68.0 vs 88.1 points, p = 0.004). Fifty-seven (81.4%) men were “very satisfied” or “satisfied” with the treatment outcomes, while nine (12.9%) respondents noted a moderate effect of residual urinary disorders on the quality of life. Significantly higher satisfaction was observed among cystostomy patients and in cases where repeated interventions were unnecessary.Conclusion. Multi-stage urethroplasty for complex anterior urethral strictures achieves efficacy in 97.3% of cases and is accompanied by high levels of quality of life and patient’s satisfaction during long-term follow-up.

Treatment of patients with anterior urethral strictures: the role of perineal urethrostomy

The article reviews the 2000-2020 literature on the use of perineal urethrostomy in the treatment of patients with anterior urethral strictures. Historical issues of the development of urethrostomy techniques are considered. The algorithms to choose the method of treatment of urethral strictures in favor of perineal urethrostomy are highlighted, according to the guidelines of the world's professional urological associations. The performance indicators of perineal urethrostomy were studied considering the age characteristics of the patients, the etiological genesis of the strictures, their length and location, as well as depending on the surgical technique and the follow-up period. Considerable attention is paid to studies devoted to the analysis of the functional results of urethrostomy, as well as the quality of life of patients associated with urination and sexual activity. Data are presented on the incidence of early and late surgical complications, including urethrostomy stenosis, as one of the most common. An analysis of studies evaluating factors that negatively affect the outcome of surgery was carried out. The main reasons for the growing demand for the technique in surgery for complex anterior urethral strictures and the importance of the technique among other treatment methods are discussed.
