This study aimed to introduce a modified Byars staged procedure and investigate its application value in patients with severe hypospadias. We retrospectively analyzed the clinical data of patients with severe hypospadias admitted to the First Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) between October 2012 and October 2022. In total, 31 patients underwent the conventional Byars procedure (conventional group), and 45 patients underwent the modified Byars staged procedure (modified group). Our modified strategy was built upon the standard Byars procedure by incorporating glansplasty during the first stage and employing a Y-shaped flap in conjunction with a glandular tunnel for urethroplasty during the second stage. Notably, there were no statistically significant differences in the preoperative baseline characteristics, duration of surgery, amount of blood loss, or occurrence of postoperative complications, including urethral fistula, stricture and diverticulum, or penile curvature, between the conventional and modified groups. However, there was a significantly lower incidence of coronal sulcus fistula (0 vs 16.1%, P = 0.02) and glans dehiscence (0 vs 12.9%, P = 0.02) in the surgical group than that in the conventional group. In addition, the modified group exhibited a notably greater rate of normotopic urethral opening (100.0% vs 83.9%, P = 0.01) and a higher mean score on the Hypospadias Objective Penile Evaluation (HOPE; mean ± standard error of mean: 8.6 ± 0.2 vs 7.9 ± 0.3, P = 0.02) than did the conventional group. In conclusion, the modified Byars staged procedure significantly reduced the risks of glans dehiscence and coronal sulcus fistula. Consequently, it offers a promising approach for achieving favorable penile esthetics, thereby providing a reliable therapeutic option for severe hypospadias.

Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Urethral length has been identified as a factor affecting postoperative continence recovery. In this meta-analysis, we examined the association between use of the maximal urethral length preservation (MULP) technique and postoperative urinary continence in patients undergoing RARP. We conducted a comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to synthesize data and calculate the odds ratio (OR) from eligible studies on continence and MULP. Six studies involving 1869 patients met the eligibility criteria. MULP was positively associated with both early continence (1 month after RARP; Z = 3.62, P = 0.003, OR = 3.10, 95% confidence interval [CI]: 1.68-5.73) and late continence (12 months after RARP; Z = 2.34, P = 0.019, OR = 2.10, 95% CI: 1.13-3.90). Oncological outcomes indicated that MULP did not increase the overall positive surgical margin rate or the positive surgical margin status at the prostate apex (both P > 0.05). In conclusion, the use of the MULP technique in RARP significantly improved both early and late postoperative continence outcomes without compromising oncological outcomes.

Asian Journal of Andrology 2025;27(2):185-188
The presentation of a foreign body in the lower urinary tract is a challenging urological emergency with highly variable management approaches. A retrospective cohort study was undertaken to identify the patients who presented with self-inserted genitourethral foreign body to adult tertiary centers within our local health network (Southern Adelaide Local Health Network, Adelaide, Australia) from October 2002 to October 2022. Patient demographics, type of foreign body, psychiatric comorbidities, retrieval techniques, complications, and readmission data were extracted. Twenty-seven cases were identified with a median age of 44 years. Twenty-three (85.2%) were male and 4 (14.8%) were female. Ten patients (37.0%) had a concurrent psychiatric illness. The most commonly inserted foreign bodies were plastic tubes/wires (29.6%). Twenty cases (74.1%) were retrieved endoscopically. Three patients (11.1%) required open cystotomy and one underwent a transperineal urethrotomy. Four patients (14.8%) represented after discharge. Two patients had repeat presentations for genitourinary foreign body insertion. A significant monotonic positive trend of foreign body presentations was identified (Mann-Kendall tau = 0.95, P = 0.043). Presentations of genitourethral foreign body insertions have trended upward over the past two decades. However, most cases were successfully managed endoscopically.

Isolated male epispadias typically presents with preputial defects and dorsal urethral dehiscence. A less common subtype, known as concealed epispadias, is distinguished by an intact prepuce. Despite its clinical relevance, there is limited literature on this variant. In this study, we retrospectively analyzed the clinical data of 86 pediatric patients with isolated male epispadias treated in Beijing Children's Hospital (Beijing, China) from May 2004 to July 2023, including 19 cases of concealed epispadias and 67 of nonconcealed epispadias. We compared clinical characteristics, preoperative diagnostics, surgical techniques, postoperative outcomes, and sexual function during follow-up between the concealed and nonconcealed groups. No significant differences were observed between the two groups regarding surgical methods, postoperative complications, or rates of urinary incontinence. However, notable distinctions were found in the age at initial diagnosis, timing of surgery, frequency of incontinence, location of the urethral meatus, and postoperative urinary incontinence scores (all P < 0.05). Given the absence of penopubic epispadias in concealed cases, we categorized glans and penile epispadias within nonconcealed epispadias as distal epispadias ( n = 40) and subsequently compared them with concealed epispadias cases. The postoperative urinary incontinence scores did not differ significantly between the concealed and distal epispadias groups. These findings suggest that concealed epispadias represents a relatively milder form of the condition, characterized by the absence of penopubic involvement, lower rates of urinary incontinence, and favorable surgical outcomes. However, the intact prepuce in concealed cases underscores the need for careful identification and early diagnosis.

Congenital lower urinary tract obstruction (CLUTO) is a spectrum of fetal malformations caused by anatomical abnormalities of the urethra, characterized by high rates of perinatal complications and mortality. The 2024 joint guideline from the European Association of Urology (EAU) and the European Society for Paediatric Urology (ESPU) introduced systematic revisions to the comprehensive management of CLUTO. Key updates encompass advancements in prenatal and postnatal screening and precise diagnosis, refined fetal prognosis assessment, clearer indications and modality selection for prenatal intervention, optimization of postnatal treatment strategies, and the establishment of a lifelong follow-up framework within an integrated care pathway. This article elucidates these key updates by comparing the 2024 EAU/ESPU guideline with the 2022 European Rare Kidney Disease Reference Network (ERKNet) consensus. It also discusses ongoing controversies and future research directions. The aim is to provide clinicians with the latest evidence-based insights to inform practice, ultimately improving outcomes and quality of life for children with CLUTO.

OBJECTIVE:
To investigate the effect of inverted-Y urethral function-preserving holmium laser enucleation of the prostate (HoLEP) on stress urinary incontinence after surgery in patients with BPH.
METHODS:
We retrospectively analyzed the clinical data on 109 cases of BPH treated in our hospital from June 2022 to May 2023 by traditional HoLEP with preservation of the apical prostatic urethral valve (group A, n = 52) or inverted-Y urethral function-preserving HoLEP (group B, n = 57). We recorded the intra- and post-operative parameters, evaluated the urinary incontinence status and post-void symptoms according to the International Continence Society standards, and analyzed the effect of inverted-Y versus traditional HoLEP in improving the postoperative urinary incontinence of the patients.
RESULTS:
The incidence rate of stress urinary incontinence after catheter removal was significantly lower in group B than in A (10.52% vs 26.92%, P = 0.027), and so was it at 2 weeks after surgery (1.75% vs 11.54%, P = 0.037), and at 1 month postoperatively (0% vs 7.69%, P = 0.033).
CONCLUSION
For the treatment of BPH, inverted-Y urethral function-preserving HoLEP is superior to traditional HoLEP with preservation of the apical prostatic urethral valve in improving stress urinary incontinence after surgery.

National Journal of Andrology 2025;31(7):625-629
OBJECTIVE:
To investigate the clinical effect of transposition of gracilis muscle flap in repairing urethral perineal fistula after Miles operation.
METHODS:
The clinical data of 3 patients with urethral perineal fistula treated in the Second Affiliated Hospital of Zhejiang University from September 2023 to November 2024 were analyzed retrospectively. All patients were male, aged from 59 to 68 years (mean 63 years). All patients underwent Miles operation because of low rectal cancer. Urethral perineal fistula occurred after 2 months to 13 years of the operation. The underlying comorbidities included diabetes (2/3), preoperative chemoradiotherapy (1/3), and chemotherapy alone (1/3). The endourethral fistula was located in the apical and membranous part of the prostate, with a diameter of 1.5-2.0 cm and a mean of 1.7 cm. Suprapubic cystostomy was performed one month before operation. In all 3 cases, perineal inverted "Y" incision was taken under general anesthesia to expose urethral fistula, cut off necrotic tissue and suture urethral fistula. The gracilis muscle of the right thigh was taken and turned through the perineal subcutaneous tunnel. and 6 stitches were suture at the urethral fistula.
RESULTS:
The operations of all 3 patients were completed successfully. The follow-up period ranged from 2 months to 12 months, with an average of 8 months. There was no case of urinary incontinence after removal of catheter 3 weeks after operation. In two patients, urethrography was reviewed 1 month after surgery to show no fistula residue and urethral stenosis, and the fistula was removed. In one patient with a history of radiotherapy, urethrography was reviewed 1 month after surgery to show a small amount of contrast overflow around the urethra, and urethrography was reviewed again 3 months after surgery to show no contrast overflow around the urethra. All the 3 patients had no disturbance of movement of the right lower limb, and the pain of different degrees of thigh incision was acceptable and basically relieved half a month after operation.
CONCLUSION
Gracilis muscle flap is one of the effective methods for repairing urethral perineal fistula after Miles operation,which has a precise surgical result and few complications.

Journal of Peking University(Health Sciences) 2024;56(6):1075-1082
OBJECTIVE:
To evaluate the surgical methods for treating distal urethral stricture.
METHODS:
The clinical data of 80 patients with distal urethral stricture in Beijing Jishuitan Hospital, Captial Medical University between January 2018 and December 2022 were retrospectively collected. Including male genital lichen sclerosus (MGLS) 33 cases, iatrogenic injury 25 cases, postoperative hypospadias 12 cases, and other causes such as trauma 10 cases. Among these cases, strictures involved the urethral meatus in 54 instances, of which 38 were treated with meatotomy (MO), 7 with penile skin flap urethroplasty (PSFU), and 9 with oral mucosa graft urethroplasty (OMGU). There were also 26 instances where strictures involved both the navicular fossa and meatus; one case underwent PSFU while 25 underwent OMGU. Based on different surgical methods used for treatment purposes we divided the patients into MO group, PSFU group and OMGU group. The age of the three groups was (48.8±20.0) years, (53.3±21.8) years and (44.5±16.4) years. The mean±SD body mass index (BMI) was (28.6±3.9) kg/m2, (29.6±3.2) kg/m2 and (29.2±4.8) kg/m2. The preoperative maximum flow rate was (5.8±2.3) mL/s, (6.8±2.4) mL/s and (5.7±3.1) mL/s.
RESULTS:
All the operations were successfully completed without Clavien Ⅲ or Ⅳ complications. The median length of strictures (measured intraoperatively) in the three groups were 1.1 (1.0, 1.6), 1.5 (1.1, 2.0) and 4.0 (2.5, 5.0) cm. The median operation time was 60.0 (60.0, 75.0), 85.0 (75.0, 112.5) and 180.0 (75.0, 330.0) min. The median estimated blood loss was 5.0 (2.0, 10.0), 15.0 (5.0, 42.5) and 180.0 (135.0, 216.3) mL. The median postoperative hospital stay was 3.5 (2.0, 5.0), 6.5 (3.5, 7.0) and 7.5 (7.0, 11.3) days. The median follow-up duration was 40.0 (26.3, 57.3), 55.0 (18.8, 62.8) and 52.5 (30.5, 64.0) months. The median postoperative maximum flow rate was 18.3 (15.5, 19.8), 19.2 (16.1, 20.1) and 17.2 (14.2, 19.6) mL/s. Among the 38 patients with MO, 33 cases had normal urination without reintervention, and 5 cases experienced recurrent strictures and required regular urethral dilation. Among the 8 patients with PSFU, 7 cases had normal urination without reintervention, and one case developed a urinary fistula, for which intervention was recommended but the patient opted to maintain the status quo. Among the 34 patients with OMGU, 28 cases had normal urination without reintervention. There were 6 instances of stenosis recurrence, with 5 cases requiring regular urethral dilations and one case requiring reconstructive surgery. The overall success rate of operation was 85.0%, and the reintervention rate was 15.0%. Statistical analysis revealed significant differences in etiologies among the three groups (P=0.002), as well as in stricture locations (P < 0.001), length of strictures (P < 0.001), operation time (P < 0.001), estimated blood loss (P < 0.001) and postoperative hospital stays (P < 0.001). However, no significant differences were observed in terms of age, BMI, history of previous urethral stricture surgeries, preoperative maximum flow rate, follow-up duration, postoperative maximum flow rate and reintervention rate. Univariate and multivariate Logistic regression analyses indicated that a history of previous urethral stricture surgeries was a risk factor for postoperative reintervention (P=0.026).
CONCLUSION
MO and PSFU are primarily suitable for treating short-segment (≤1.5 cm) distal penile urethral strictures, whereas OMGU is more appropriate for longer segment strictures. MO and OMGU can both be utilized in managing MGLS cases. PSFU and OMGU are more conducive to improving the appearance of the urethral meatus. The success rate of surgical management of distal penile urethral stricture is 85.0%, 15.0% of the patients still require surgical intervention after surgery, and having history of previous urethral stricture surgeries is a risk factor for postoperative reintervention.

Kathleen Adryon Tan ; Maria Sarah Lenon
Philippine Journal of Pathology 2023;8(2):43-47
This is a rare case of a mucosal melanoma, located in the urethra of a 59-year-old male. Malignant melanomas of the genitourinary tract are rare, representing <1% of malignancies in the genitourinary tract, and <0.1% of all melanomas. In the male genitourinary tract, the most affected sites are the glans penis and the distal urethra in the fossa navicularis. Urethral melanomas comprise 4% of all urethral cancers.

Urethrocutaneous fistula may complicate hypospadias repair. We noticed that double-layered preputial dartos flaps added to tubularized incised plate urethroplasty can reduce the risk of urethrocutaneous fistula. The aim of this study was to compare the outcomes of tubularized incised plate urethroplasty with double-layered preputial dartos flaps to with single-layered local fascial flaps in preventing urethrocutaneous fistula. A retrospective cohort study was conducted between January 2017 and December 2020 at Jordan University Hospital (Amman, Jordan). Boys who were aged between 6 months and 5 years, diagnosed with distal hypospadias, and not circumcised were included. The primary outcome was the occurrence of urethrocutaneous fistula in patients who underwent tubularized incised plate urethroplasty with a double-layered fascial flap. The results showed a total of 163 boys with distal hypospadias; among them, 116 patients underwent tubularized incised plate urethroplasty with a single-layered fascial flap, and 47 underwent tubularized incised plate urethroplasty with a double-layered fascial flap. The development of urethrocutaneous fistula was higher in the group receiving tubularized incised plate urethroplasty with a single-layered fascial flap than in the group receiving tubularized incised plate urethroplasty with a double-layered fascial flap after 1 month, 6 months, and 12 months (6.9% vs 0, 10.3% vs 0, and 5.2% vs 0, respectively), and the difference after 6 months was statistically significant (P = 0.02).
