Qualitative Analysis of Patient Experiences Reaching Urethroplasty for Recurrent Urethral Stricture Disease.

PURPOSE: Despite the inferior outcomes, urethral stricture patients often undergo multiple endoscopic procedures prior to undergoing definitive urethroplasty. We sought to qualitatively evaluate the patient experience of obtaining urethroplasty to better understand the impact of this experience on quality of life. MATERIALS AND METHODS: Patients treated with urethroplasty between September 2019 and July 2021 were identified and invited to participate in our study if they had undergone ≥ 2 endoscopic procedures prior to urethroplasty. Semistructured telephone interviews were conducted, coded, and analyzed using an iterative inductive-deductive approach. RESULTS: Of the 105 urethroplasty patients during the study period, 50 (47.6%) had undergone ≥ 2 endoscopic procedures prior (IQR 3-5), of whom 20 participated in the study. Qualitative themes related to repeat endoscopic procedures included unmet treatment expectations, dissatisfaction with catheterization and repeat procedures, and negative impacts of recurrent stricture symptoms and treatments on quality of life. External factors associated with a delay to urethroplasty included financial constraints, surgeon access, and time off work. CONCLUSIONS: A trajectory of declining quality of life and unmet treatment expectations are the primary factors driving the decision to proceed with urethroplasty. However, external factors such as recovery costs and access to specialists play important roles in delaying surgery. These findings illustrate the need for improved community provider education and patient counseling to better inform expectations of both patients and providers with various treatment outcomes. Furthermore, these data highlight the need to improve access to specialized care for urethral stricture patients.

Deep Phenotyping the Anterior Urethral Stricture: Characterizing the Relationship Between Inflammation, Fibrosis, Patient History, and Disease Pathophysiology.

PURPOSE: Anterior urethral stricture disease (aUSD) is a complex, heterogeneous condition that is idiopathic in origin for most men. This gap in knowledge rarely affects the current management strategy for aUSD, as urethroplasty does not generally consider etiology. However, as we transition towards personalized, minimally invasive treatments for aUSD and begin to consider aUSD prevention strategies, disease pathophysiology will become increasingly important. The purpose of this study was to perform a deep phenotype of men undergoing anterior urethroplasty for aUSD. We hypothesized that unique biologic signatures and potential targets for intervention would emerge based on stricture presence/absence, stricture etiology, and the presence/absence of stricture inflammation. MATERIALS AND METHODS: Men with aUSD undergoing urethroplasty were recruited from one of 5 participating centers. Enrollees provided urethral stricture tissue and blood/serum on the day of surgery and completed patient-reported outcome measure questionnaires both pre- and postoperatively. The initial study had 3 aims: (1) to determine pediatric and adult subacute and repeated perineal trauma (SRPT) exposures using a study-specific SRPT questionnaire, (2) to determine the degree of inflammation and fibrosis in aUSD and peri-aUSD (normal urethra) tissue, and (3) to determine levels of systemic inflammatory and fibrotic cytokines. Two controls groups provided serum (normal vasectomy patients) and urethral tissue (autopsy patients). Cohorts were based on the presence/absence of stricture, by presumed stricture etiology (idiopathic, traumatic/iatrogenic, lichen sclerosus [LS]), and by the presence/absence of stricture inflammation. RESULTS: Of 138 enrolled men (120 tissue/serum; 18 stricture tissue only), 78 had idiopathic strictures, 33 had trauma-related strictures, and 27 had LS-related strictures. BMI, stricture length, and stricture location significantly differed between cohorts (P < .001 for each). The highest BMIs and the longest strictures were observed in the LS cohort. SRPT exposures did not significantly differ between etiology cohorts, with > 60% of each reporting low/mild risk. Stricture inflammation significantly differed between cohorts, with mild to severe inflammation present in 27% of trauma-related strictures, 54% of idiopathic strictures, and 48% of LS strictures (P = .036). Stricture fibrosis did not significantly differ between cohorts (P = .7). Three serum cytokines were significantly higher in patients with strictures compared to stricture-free controls: interleukin-9 (IL-9; P = .001), platelet-derived growth factor-BB (P = .004), and CCL5 (P = .01). No differences were observed in the levels of these cytokines based on stricture etiology. However, IL-9 levels were significantly higher in patients with inflamed strictures than in patients with strictures lacking inflammation (P = .019). Degree of stricture inflammation positively correlated with serum levels of IL-9 (Spearman's rho 0.224, P = .014). CONCLUSIONS: The most common aUSD etiology is idiopathic. Though convention has implicated SRPT as causative for idiopathic strictures, here we found that patients with idiopathic strictures had low SRPT rates that were similar to rates in patients with a known stricture etiology. Stricture and stricture-adjacent inflammation in idiopathic stricture were similar to LS strictures, suggesting shared pathophysiologic mechanisms. IL-9, platelet-derived growth factor-BB, and CCL5, which were elevated in patients with strictures, have been implicated in fibrotic conditions elsewhere in the body. Further work will be required to determine if this shared biologic signature represents a potential mechanism for an aUSD predisposition.

Multi-Institutional Outcomes of Dorsal Onlay Buccal Mucosal Graft Urethroplasty in Patients With Postprostatectomy, Postradiation Anastomotic Stenosis.

PURPOSE: The treatment of urethral stenosis after a combination of prostatectomy and radiation therapy for prostate cancer is understudied. We evaluate the clinical and patient-related outcomes after dorsal onlay buccal mucosal graft urethroplasty (D-BMGU) in men who underwent prostatectomy and radiation therapy. MATERIALS AND METHODS: A multi-institutional, retrospective review of men with vesicourethral anastomotic stenosis or bulbomembranous urethral stricture disease after radical prostatectomy and radiation therapy from 8 institutions between 2013 to 2021 was performed. The primary outcomes were stenosis recurrence and development of de novo stress urinary incontinence. Secondary outcomes were surgical complications, changes in voiding, and patient-reported satisfaction. RESULTS: Forty-five men were treated with D-BMGU for stenosis following prostatectomy and radiation. There was a total of 7 recurrences. Median follow-up in patients without recurrence was 21 months (IQR 12-24). There were no incidents of de novo incontinence, 28 patients were incontinent pre- and postoperatively, and of the 6 patients managed with suprapubic catheter preoperatively, 4 were continent after repair. Following repair, men had significant improvement in postvoid residual, uroflow, International Prostate Symptom Score, and International Prostate Symptom Score quality-of-life domain. Overall satisfaction was +2 or better in 86.6% of men on the Global Response Assessment. CONCLUSIONS: D-BMGU is a safe, feasible, and effective technique in patients with urethral stenosis after a combination of prostatectomy and radiation therapy. Although our findings suggest this technique may result in lower rates of de novo urinary incontinence compared to conventional urethral transection and excision techniques, head-to-head comparisons are needed.

Affirming Long-Term Outcomes After Contemporary Urethroplasty: The Adverse Impact of Increasing Stricture Length, Lichen Sclerosus, Radiation, and Infectious Strictures.

PURPOSE: There is a paucity of reported long-term outcomes after contemporary urethroplasty. Our objective is to determine the long-term success of modern urethroplasty and identify factors associated with stricture recurrence in this context. MATERIALS AND METHODS: Patients undergoing urethroplasty from July 2003 to May 2013 with at least 100 months of follow-up were identified. Long-term outcomes including stricture recurrence and patient satisfaction were evaluated by review of regional/provincial electronic records and telephone interview. Urethroplasty failure was defined as a recurrent stricture (<16F) confirmed on cystoscopy. Cox regression was used to evaluate variables associated with long-term stricture recurrence. RESULTS: A total of 733 patients were identified with ≥ 100 months follow-up. Median patient age was 45 years, stricture length was 4.7 cm, and 85.8% failed prior endoscopic treatment. At a median follow-up of 12.3 years, 89 recurrences were observed. Cumulative incidence of stricture recurrence was 6%, 10%, and 12% after 1, 5, and 10 years, respectively. From a patient-reported perspective, 89% of patients reported being satisfied with the outcome of surgery. On multivariable analyses, increasing stricture length (HR 1.1, 95% CI 1.05-1.15; P < .001) and stricture etiology (P < .001), in particular lichen sclerosus (HR 4.46, 95% CI 2.25-9.53), radiation (HR 4.25, 95% CI 1.65-10.9), and infectious strictures (HR 5.27, 95% CI 2.03-13.7), were independently associated with stricture recurrence. CONCLUSIONS: This study affirms the widely held belief that modern urethroplasty provides high long-term patency and patient-reported satisfaction. Patients with longer strictures as well as those with lichen sclerosus, radiation, and infectious etiologies have a higher hazard of stricture recurrence in the long term.

Surgical management of complex curvature in Peyronie's disease.

PURPOSE: About 10% of Peyronie's patients are complex cases with severe curvature (>60 degrees), ventral plaque, multiplanar curvature, hour-glass/hinge deformity, notching deformity, and ossified plaque. In patients with complex Peyronie's disease (PD), different techniques (shortening procedures, lengthening procedures, and penile prosthesis implantation (IPP)) may be necessary to achieve successful result. This review aims to analyze the various surgical techniques employed in the management of Peyronie's disease, with a specific focus on patients with complex deformity. METHODS: Articles focusing on the surgical management of complex curvature in Peyronie's disease were searched in MEDLINE and PubMed published between 1990 and 2023. RESULTS: Shortening procedures are linked to penile shortening and are not recommended for complex cases such as notching, hour-glass deformity, or ossified plaque. Lengthening procedures are suitable for addressing complex curvatures without erectile dysfunction (ED) and are a more appropriate method for multiplanar curvatures. Penile prosthesis implantation (IPP), with or without additional procedures, is the gold standard for patients with ED and Peyronie's disease. IPP should also be the preferred option for cases of penile instability (hinge deformity) and has shown high satisfaction rates in all complex cases. CONCLUSION: While surgical interventions for complex curvature in Peyronie's disease carry inherent risks, careful patient selection, meticulous surgical techniques, and post-operative care can help minimize complications and maximize positive outcome.

High frequency of concomitant squamous metaplasia in bulbar urethral stricture and its association with reconstructive delay and urethral rest.

PURPOSE: To determine the prevalence of concomitant squamous metaplasia (SM), the initial histological change from normal urethra to urethral stricture, in bulbar urethral strictures and to investigate the associated clinical factors. METHODS: A retrospective review was conducted on 165 male patients with bulbar urethral strictures who underwent excision and primary anastomosis (EPA) between 2010 and 2020, for whom complete clinical data and excised urethral specimens were available. An experienced pathologist histologically evaluated concomitant SM in paraffin sections of the proximal end of the excised urethra blinded to the clinical data. Disease duration was calculated as the period from the initial diagnosis of urethral stricture to the date of EPA. The association between concomitant SM and clinical background was investigated. RESULTS: SM was identified in 86 (52.1%) patients. The median disease duration in patients with SM (38 months) was significantly longer than that in patients without SM (9 months, p < 0.0001). In multivariate analysis, the longer disease duration, non-traumatic stricture etiology, and failure to maintain urethral rest with urinary diversion via a suprapubic tube for more than 90 days were independent factors predicting concomitant SM. No significant difference was observed in success rates of EPA between patients with SM (93.2%) and those without SM (97.5%, p = 0.18). CONCLUSIONS: Reconstructive urologists need to be aware that concomitant SM is frequent in patients with bulbar urethral stricture, especially in those with long disease duration and those who were voiding volitionally during the period of urethral rest.

Staged urethroplasty with groin full-thickness skin graft for managing complex anterior urethral strictures: surgical outcomes and predictive factors.

PURPOSE: To describe outcomes of staged-urethroplasty in complex anterior urethral strictures using full-thickness-skin-graft (FTSG) harvested from the hairless groin area, and to identify factors influencing successful outcomes. METHODS: Through retrospective chart review, we identified a total of 67 men who underwent the first-stage operation (grafting) using groin-FTSG for staged-urethroplasty to treat complex anterior urethral strictures unsuitable for one-stage urethroplasty. Among these, 59 underwent the second-stage operation (tubularization) at a median duration of 5.1-months after grafting. Patients were assessed for outcomes as scheduled after tubularization outcomes were analyzed only for 48 patients for whom ≥ 1-year follow-up data after tubularization were available. Their mean follow-up duration was 27.1 months. Success was defined as achieving physiologic voiding without requiring further procedures. RESULTS: Median stricture-length was 5.5 cm in all 67 patients. After grafting, neourethral-opening-narrowing occurred in 18. Partial graft-loss occurred in 8, of whom only 3 underwent re-grafting. The percentage of patients who achieved successful outcomes was 81.3%. Improvements in maximum-urine-flow-rate and post-void-residual-urine-volume were maintained until the last follow-up visit. A urethrocutaneous-fistula occurred in one patient, while meatal-stenosis occurred in two. On multivariate-regression-analysis, the presence of neourethral-opening-narrowing was the only predictor of non-success after tubularization. Furthermore, the presence of hypertension, longer stricture-length, and a history of prior direct-vision-internal-urethrotomy were predictors of the occurrence of neourethral-opening-narrowing. CONCLUSION: Staged-urethroplasty using groin-FTSG is well worth considering as a useful therapeutic option for complex anterior urethral strictures, with an acceptable success rate and low morbidity. The absence of neourethral-opening-narrowing after the first-stage operation leads to success.

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

PURPOSE: 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. METHODS: 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. RESULTS: 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 22.8 months. 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 29 months. Two predictors of complications were identified by multivariate analysis: catheterization duration and urethroplasty technique. The reoperation rate was 30.5%. CONCLUSION: 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.

Small intestinal submucosa graft bulbar urethroplasty is a viable technique: results compared to buccal mucosa graft urethroplasty after propensity score matching.

PURPOSE: Small intestinal submucosa (SIS) graft urethroplasty has been employed to decrease buccal mucosa morbidity and facilitate the procedure. The first published series had a short follow-up, inhomogeneous patient selection, and a lack of a control group. Our purpose is to report treatment outcomes at 13 years in a propensity score-matched cohort comparing bulbar urethroplasty with SIS (SISU) or buccal mucosa (BMU). METHODS: From our institutional database of 1132 bulbar urethroplasties, we used propensity score matching with the nearest-neighbor method without replacement to generate a study sample of 25 BMU and 25 SISU. Failure was defined as any treatment after urethroplasty. Survival analyses were used to analyze treatment failure occurrence with data censored at 156mo. RESULTS: Matching resulted in a complete correction of bias between the two samples except for the follow-up duration, which was slightly longer in the SIS group. The cumulative treatment success probability of BMU and SISU at 156mo was 83.4% and 68%, respectively. At multivariable Cox regression, SIS graft, previous urethrotomy, stricture length, and lower postoperative Qmax (within 2mo after catheter removal) were predictors of failure. Stricture length had a more remarkable effect in SISU, with estimated survival probabilities from the Cox model lower than 80% in strictures > = 3 cm. CONCLUSION: SIS has poorer outcomes compared to BM but may still be useful when BM grafting is not possible. The best candidates for SISU, with similar success to BMU, are patients with strictures shorter than 3 cm, preferably without a history of DVIU.

What should be next in lifelong posterior hypospadias: Conclusions from the 2023 ERN eUROGEN and EJP-RD networking meeting.

BACKGROUND: A congenital disease is for life. Posterior hypospadias, the severe form of hypospadias with a penoscrotal, scrotal, or perineal meatus, is a challenging condition with a major impact on lifelong quality of life. AIM: Our network meeting is aimed to identify what is currently missing in the lifelong treatment of posterior hypospadias, to improve care, quality of life, and awareness for these patients. METHODS: The network meeting "Lifelong Posterior Hypospadias" in Utrecht, The Netherlands was granted by the European Joint Programme on Rare Diseases-Networking Support Scheme. There was a combination of interactive sessions (hackathons) and lectures. This paper can be regarded as the last phase of the hackathon. RESULTS: Surgery for hypospadias remains challenging and complications may occur until adulthood. Posterior hypospadias affects sexual function, fertility, and hormonal status. Transitional care from childhood into adulthood is currently insufficiently established. Patients should be more involved in defining desired treatment approach and outcome measures. For optimal outcome evaluation standardization of data collection and registration at European level is necessary. Tissue engineering may provide a solution to the shortage of healthy tissue in posterior hypospadias. For optimal results, cooperation between basic researchers from different centers, as well as involving clinicians and patients is necessary. CONCLUSIONS: To improve outcomes for patients with posterior hypospadias, patient voices should be included and lifelong care by dedicated healthcare professionals guaranteed. Other requirements are joining forces at European level in uniform registration of outcome data and cooperation in basic research.

Long-term Sexual Function and Quality of Life in Women Following Substitution Urethroplasty.

PURPOSE: To assess the long-term quality of life (QOL) and sexual function (SF) in women who underwent either dorsal on-lay (DO) or ventral inlay (VI) urethroplasty for urethral stricture disease. METHODOLOGY: Between January 2016 and September 2022, women who underwent either dorsal on-lay (DO) or ventral inlay (VI) urethroplasties and had at least a six-month follow-up been included. Using the Female Sexual Function Index (FSFI) and WHO-QOL bref questionnaires, the QOL and SF were evaluated. Scores were compared between the two groups after being examined for internal validity. A sub-group analysis was carried out based on the procedure's success. RESULTS: With follow-up periods ranging from 6 to 86 months, 25 patients who received VI urethroplasty and 10 patients who underwent DO urethroplasty were included. Both scores demonstrated strong internal consistency. The cumulative QOL and FSFI scores were comparable in both groups (p = 0.53 and p = 0.83, respectively). Significantly high scores were noted in the physical health domain (76.5 ± 9.9 vs 62.33 ± 10.97; p = 0.03; (95% CI = 0.72-24.4)) and the environmental domain (75.75 ± 3.84 vs 66.00 ± 4.24; p = 0.01 (95% CI = 2.64-16.85) in patients with successful VI and DO urethroplasties respectively. Addictions, low socioeconomic status and protracted symptom duration were associated with low QOL scores. Old age was related to low FSFI scores. CONCLUSION: Substitution urethroplasty, despite the approach, showed good QOL and SF scores. Long symptom duration, addictions, and poor socioeconomic status were associated with low QOL whereas old age independently influenced low FSFI scores.

Comparison of outcome of TIP urethroplasty with or without Buck's Fascia repair.

OBJECTIVE: TIP is the most common preformed type of Urethroplasty. The intermediate barrier is used as a waterproofing layer to prevent fistula formation. Many tissues have been utilized as a barrier layer, with varying success rates. The search for a better intermediate layer will continue. In this study, we aim to evaluate the role of Buck's Fascia as a covering for the neo-urethra to prevent fistula formation in patients who underwent Snodgrass Urethroplasty. METHODS: This prospective study was conducted between 2018 and 2022. Patients were randomly assigned to either Group 'A' or Group 'B'. Group A included patients who underwent the Snodgrass procedure with a Buck's Fascia cover, while Group B included patients whose neo-urethra was covered with the dartos flap. These patients were closely monitored for the development of short- and long-term complications in both groups, and the results were recorded. RESULTS: The study involved 164 patients, who underwent midpenile and distal hypospadias repair using the Snodgrass technique. In Group 'A' (84 patients), the neo-urethra was covered with Buck's Fascia, while in Group 'B' (80 patients), the neo-urethra was covered with the dartos flap. The mean age of the children was (23.06 ± 16.12) months in group 'A' & (26.06 ± 14.07) months in group 'B'. mean operating time was (40 ± 11.43) minutes, in Group 'A', and (70 ± 17.43) minutes, in Group 'B'. Meatal stenosis occurred in 3.57% of children in Group 'A' and 10% of patients in Group 'B'. Urethral fistulas were encountered in 2.35% of cases in Group 'A'and 10% in Group 'B'. The difference between the groups was statistically significant.

The long-term consequences of the hypospadias salvage repair issue.

PURPOSE: To present the long-term results of redo-hypospadias at our tertiary referral center following a failed prior repair. METHODS: One hundred sixty-four individuals with a history of unsuccessful repairs qualified for our retrospective cohort study. Our inclusion criteria were as follows: pre-operative data that was accessible, redo-hypospadias that was successfully repaired, and at least three years of follow-up at the last hospital visit. RESULTS: The mean patient age was 91.3 ± 21.1 months. The mean follow-up after successful repair was 41.3 ± 3.1 months. Ninety-two (group A) had one prior repair, and 72 (group B) had 2 or 3 repairs. Group A underwent six primary techniques: 32 underwent Onlay Island Flap (OIF), 10 underwent Mathieu, 12 underwent Tubularized Incised Plate Urethroplasty (TIPU), 8 underwent Urethral Mobilization (UM), and 34 underwent Buccal Mucosal Graft (BMG) { dorsal inlay Graft Urethroplasty (DIGU) in 4 and staged BMG in 30 patients}. In group B, four procedures were used: TIPU in 4, UM in 6, and BMG in 62 (staged BMG in 50 cases and DIGU in 12). CONCLUSIONS: The selected type of repair will depend on many factors, like residual healthy local skin and expertise. Safe techniques for repair of redo hypospadias after its 1st failure include TIPU, Mathieu, UM, OIF, and DIGU for distal varieties. After 2nd or 3rd repair DIGU, UM, and TIPU can be performed in distal types, while staged BMG can be applied for proximal ones.

Urethral carcinoma after skin substitution urethral reconstruction.

Urethral cancer after urethral reconstruction is an under-recognized, uncommon disease associated with significant morbidity and mortality. The survival rates of patients with carcinoma of the bulbar urethra are as low as 20%-30%. Stricture recurrence and unrecognized malignant changes present prior to reconstruction are major risk factors for urethral cancer. Skin substitution urethroplasty is subjected to higher rates of recurrence, which lends to the potential for carcinogenesis. We present a case of a 59-year-old male who underwent multi-stage skin substitution urethroplasty who developed urethral carcinoma 20 years later.

Advancing Intraoperative Assessment of Urethral Stricture Anatomic Variation: A Prospective Proof-of-Concept Study.

INTRODUCTION: Urethral strictures, particularly those refractory to endoscopic interventions, are commonly treated through open urethroplasty. However, predicting recurrence in homogeneous patient populations remains challenging. METHODS: To address this, we developed an intraoperative urethral stricture assessment tool aiming to identify comprehensive risk predictors. The assessment includes detailed parameters on stricture location, length, urethral bed width, spongiosum thickness, obliteration grade, and spongiofibrosis extension. The tool was prospectively implemented in 106 men with anterior one-stage augmentation urethroplasty from April 2020 to October 2021. RESULTS: An intraoperative granular assessment of intricate stricture characteristics is feasible. Comparative analyses revealed significant differences between bulbar and penile strictures. Bulbar strictures exhibited wider urethral beds and thicker spongiosum compared to penile strictures (all p < 0.001). The assessment showed marked variations in the degree of obliteration and spongiofibrosis extension. CONCLUSION: Our tool aligns with efforts to standardize urethral surgery, providing insights into subtle disease intricacies and enabling comparisons between institutions. Notably, intraoperative assessment may surpass the limitations of preoperative imaging, emphasizing the necessity of intraoperative evaluation. While limitations include a single-institution study and limited sample size, future research aims to refine this tool and determine its impact on treatment strategies, potentially improving long-term outcomes for urethral strictures.

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.

Risk factors and timing of complication presentation following primary hypospadias repair in adolescents.

OBJECTIVES: To evaluate the risk factors for postoperative complications in adolescents who undergo primary hypospadias repair and determine the time required for complication detection. METHODS: Our study included patients classified as Tanner stages three to five who underwent primary hypospadias repairs at our hospital from January 2015 to August 2022. The patients' baseline information, clinical characteristics, postoperative complications, and time to complication detection were collected. Cox regression analysis, ROC curves, Kaplan-Meier survival analyses, and the Mann-Whitney U test were used. RESULTS: The study comprised 143 patients, with a median age of 12.58 years. Postoperative complications were experienced by 66 patients. The length of the urethral defect was identified as an independent risk factor for postoperative complications. The ROC curve analysis identified 3 cm as the optimal cutoff value for the length of the urethral defect. The median time to complication detection was 30.5 days (IQR 23 to 209.25). 89.4% of the complications were identified within the first year. Patients with a urethral defect of <3 cm experienced a significantly longer time for the detection of urethral fistula compared to those with a urethral defect of ≥3 cm (p = 0.047). CONCLUSIONS: Our data indicate that adolescents with a urethral defect ≥3 cm have a higher risk of postoperative complications. Although most complications were identified within the first year, conducting long-term follow-ups for adolescents is recommended to identify potential subsequent complications that may arise from persistent urethral alterations.

Preoperative topical estrogen application in the management of hypospadias: a systematic review.

Local estrogen therapy has been explored as an alternative to conventional testosterone therapy in children requiring urethroplasty for hypospadias. Our objective is to evaluate if preoperative estrogen stimulation reduces post-urethroplasty complications and enhances penile dimensions. A systematic search was conducted on various databases, selecting only randomized controlled trials (RCTs) that tested estrogen on hypospadias patients under 18 years. Articles underwent sorting following PRISMA guidelines and bias risk was assessed using the JBI clinical appraisal tool for RCTs. Out of 607 screened records, 10 underwent full-text review, and 4 randomized controlled trials (RCTs) were selected for analysis. The total patient cohort across studies was 387 with 174 in the estrogen group. All studies utilized topical estrogen, but in different formulations and timings. Prudence is necessary for interpreting results due to variations in formulation, timing, and hypospadias type across studies. Limited by a small number of studies and outcome presentation non-uniformity, the review suggests no change in penile dimensions or postoperative complications with topical estrogen. Further research is needed to explore wound-healing properties of estrogen in hypospadias through animal and human studies.Registration and protocol: Registered in Prospero CRD42024502183.

High fibre and fluid intake increase the success of hypospadias surgery.

INTRODUCTION: Hypospadias is a congenital malformation of the urethral meatus in the ventral penis that requires surgery. Fibre and fluid intake can accelerate the healing process, act as an anti-inflammatory and support the success of surgery. Based on hypospadias objective scoring evaluation (HOSE) scoring, this study aims to determine whether a high-fibre diet and adequate fluid intake affect the outcome of hypospadias surgery. MATERIALS AND METHODS: This analytic observational study used a case-control study design on 104 post-operative hypospadias patients at Ulin and Siaga Hospital Banjarmasin from 2018 to 2023 with quota sampling. Data were collected using personal data forms with hypospadias objective scoring evaluation (HOSE) and semi-quantitativefood frequency questionnaire (SQ-FFQ), which were analysed using a multinomial logistic regression test. RESULTS: Patients with less-fibre-intake had a 99.10% lower chance of having an excellent surgical outcome than patients with moderate-fibre-intake (Adjusted Odds Ratio, Adj. OR: 0.009, 95% Confidence Intervals; 95%CI: 0.000, 0.249), and it was statistically significant. The study did not find any association between fluid intake and surgical outcome, this could be due to the fact that most of the patient had good fluid intake. CONCLUSION: The study found that high fibre intake increases the success of hypospadia surgery.

[Non-transecting anastomotic urethroplasty for strictures of the bulbar urethra. Systematic review].

The results of using non-transecting anastomotic urethroplasty in men with bulbous urethral strictures are presented in the review. A total of 25 original publications were found, including 20 foreign and 5 Russian articles. The studies included from 1 to 358 patients who underwent anastomotic urethroplasty without transection of the corpus spongiosum (average number of patients in a study was 54). Etiological factors were indicated in 17 articles. Most studies (10 out of 17) indicated idiopathic etiology as the predominant one. There was no correlation between the results of the procedure and the etiology of urethral stricture. The mean length of urethral stricture in the vast majority of studies was less than 2 cm, and only in a few studies it was larger, with a maximum mean value of 3.9 cm. Postoperative complication rates were reported in 20 studies and ranged from 0% to 23.9% within one study (median 8.4%). In general, mild complications occurred, corresponding to category I-II according to the Clavien-Dindo classification. The incidence of erectile dysfunction was evaluated in 18 studies and ranged from 0% to 23% (average value of 6.5%). The success of non-transecting anastomotic urethroplasty averaged 94.7% (82-100%) with a median postoperative follow-up of 24.5 months (3-150 months). In 9 out of 25 studies, an additional comparison with transecting technique was done. In 6 studies, the superiority of the non-transecting technique in terms of treatment success and preservation of sexual function was found. The obtained results showed the high efficiency and safety of non-transecting anastomotic urethroplasty in case of short strictures of the bulbous urethra.
