Objective: To present the technique and results of 2-stage mesh-graft urethroplasty, as described by Schreiter in 1984.
Methods: 11 patients with a stricture of the anterior urethra were treated according to this urethroplasty (pedicle skin flap). The site of the stricture was penile in 4 cases and perineoscrotal in 7 cases, and the mean length was 7.7 cm (range: 3 to 12.5).
Results: 10 patients were treated in 2 stages, while the remaining patient has a persistent perineal urethrostomy. With a mean follow-up of 3.5 years (range: 14 to 77 months), 9 patients obtained a satisfactory result with no radiographic recurrence, but with persistent nocturia (x 2/night), a mean peak flow rate of 12.8 ml/s, and a mean residual urine of 55 ml present in 8 our of 9 cases. One complete failure was observed, following complete recurrence of the stricture due to the limited dimensions of the skin flap at the 2nd stage.
Conclusion: This technique constitutes a useful salvage solution after failure of a one-stage urethroplasty. It can be used to treat extensive strictures of the anterior urethra by reconstituting a good quality urethral lumen with well vascularized tissue. It also has the advantage of avoiding the presence of hair follicles and allows the two stages to be performed at a brief interval.

Aim: This study aimed to examine the correlations between specific urethral function parameters observed in urodynamic testing and selected urethral characteristics evaluated by pelvic floor ultrasonography. Additionally, the presence of urethral funneling during straining was evaluated in female patients referred for surgical treatment of stress urinary incontinence.
Material And Methods: A retrospective study was conducted on 192 female patients referred for surgical treatment of stress urinary incontinence with the use of retropubic tension-free vaginal tape.

Objectives: To evaluate the surgical and patient-reported outcomes of YV-plasty in patients with refractory bladder neck stenosis (BNS) following transurethral prostate surgery.
Methods: This retrospective study reviewed five patients who underwent YV-plasty for BNS between January 2021 and October 2023. The surgical procedure involved a midline lower abdominal incision to expose the bladder neck.

Article Synopsis
- The lower urinary tract, consisting of the bladder and urethra, develops from the cloaca, with the bladder forming from the urogenital sinus and the urethra extending into the genital tubercle.
- Engineering a fully functional bladder lining is challenging, and the urethral epithelium's immune roles are under-researched, highlighting the need for a better understanding of the epithelial and mesenchymal interactions that drive development.
- This study identified specific genes involved in bladder and urethra development in mice, revealing differences in gene expression patterns related to sex and offering insights for future regenerative therapies.
An Outside-the-Box Approach for Treating a Rare Case of Urethrovaginal Fistula.

Urethrovaginal fistulas are rare complications often arising from urethrovaginal injuries commonly due to obstetrical trauma, urethral surgeries, pelvic fractures, or neoplastic treatments. Here, we present a unique case involving a 23-year-old female patient with a large urethrovaginal fistula and complete anterior vaginal wall sloughing following prolonged obstructed labor. Nine months post-cesarean, she reported urine leakage via the vagina upon catheter removal, which intensified in an erect posture.

Background: In proximal hypospadias, ventral curvature is invariable and most have penoscrotal transposition, and we observed that the base of the penis (BOP) was located on the inferior aspect of the pubic bones in those, in contrast to the location of the BOP at the anterior end in normal penises. We also observed an unfused bulbospongiosus muscle (BSM) at surgery in those. The aim was to assess the impact of repairing the unfused BSM or transection and straightening of the urethral plate at the first operation on the low BOP.
