Objective: Transverse island pedicle flap (TIPF) plus transected urethral plate-preserving urethroplasty is increasingly used for treatment of severe hypospadias. We aimed to reduce the occurrence of urethral strictures in patients undergoing such procedures.
Methods: Sixty-five patients with severe hypospadias were enrolled. Thirty-two patients underwent onlay-tube-onlay urethroplasty (Group A), and 33 patients underwent modified Duplay urethroplasty (Group B). Postoperative complications were recorded, including fistulas, urethral strictures, and diverticula.
Results: Three patients (9.4%) in Group A and 10 patients (30.3%) in group B had urethrocutaneous fistulas. Three patients (9.4%) in Group A and 0 patients (0%) in Group B had urethral strictures. No patient in the two groups had symptoms of diverticulum or penile chordee. The results of uroflowmetry were better in Group B than Group A, when comparing uroflow patterns.
Conclusions: TIPF plus transected urethral plate-preserving urethroplasty can lower the occurrence of stricture, which is a challenging complication. The occurrence of stricture was lower in patients who underwent modified Duplay urethroplasty, and neourethral function and quality were better in these patient. Thus, this modified procedure can be used for treatment of severe hypospadias.

Analysis of Patients with Urethral Stricture in Kidney Transplant Recipients.

Background: We aimed to assess the rates of urethral stricture in transplant recipients, analyse patients with urethral strictures and present the posttreatment follow-up outcomes.
Methods: Between 2004 and 2023, a retrospective examination was conducted on kidney transplant recipients who underwent removal of ureteral catheters through retrograde cystoscopy at our facility or referred from external centres. The collected data encompassed patient demographics, pre- and posttransplant maximum urinary flow rate, specifics of stenosis, surgical interventions and outcomes from a 1-year follow-up.
Introduction Balanitis xerotica obliterans (BXO) can cause phimosis, meatal stenosis, and urethral strictures. However, management of these conditions in BXO patients is difficult. Surgical interventions, with their own risks and complications, demonstrate higher rates of disease recurrence.

Purpose: In patients with prostate cancer (PCa), focal therapy with High-Intensity Focused Ultrasound (HIFU) combined with benign prostatic hyperplasia (BPH) surgery has been used to improve immediate post-operative voiding symptoms. Our study aimed to evaluate the functional outcomes of patients undergoing simultaneous holmium laser enucleation of the prostate (HoLEP) + HIFU and compare them to those who underwent HoLEP for bladder outlet obstruction secondary to BPH.
Methods: We performed retrospective review of patients who underwent HoLEP + HIFU or HoLEP between June 2017 and May 2024.
No Right Way: Removal of a Pencil Foreign Body From a Male Urethra.

Urology, Sunderland Royal Hospital, Sunderland, GBR.
Foreign body insertion into the urethra is uncommonly encountered in urology practice. Such insertion can result in a myriad of problems including bleeding, infectious sequelae, urinary retention, urethral injury or rupture, and resultant urethral stricture formation. This article describes a case in which an elderly male inserted a pencil into his urethra, which subsequently became lodged and required removal under regional anesthesia in the operating theater.
