Urethral strictures are a frequent source of lower urinary tract symptoms in men. Open urethroplasty is regarded as the gold-standard treatment for urethral stricture disease. The treatment for urethral strictures is a continually evolving process and there is renewed controversy over the best approach to take in reconstructing the urethra, since the superiority of one approach over another has not yet been clearly defined. Anterior urethroplasty can be treated, with low morbidity, in an outpatient surgical setting, thus decreasing the impact of urethroplasty. In order to improve outcome in adult patients when the penile shaft is involved, reconstructive urethral surgeons have learned to apply the principles of delicate tissue handling, and the development of minimally invasive techniques. Genital or extra-genital skin has been used as a free graft or harvested as a flap for some time, thanks to its location, hairless skin and durability. Since the early 1990s, the use of oral mucosa was introduced in genital reconstructive surgery and has become popular for urethral reconstructions. Urethral reconstructive surgery is changing rapidly and this change has posed problems for surgeons who see the principles that previously defined their profession becoming obsolete or unworkable. New techniques and new engineered material are a part of our future.

Robot-assisted ureteral reconstruction for managing kidney transplant patients with ureteric complications.
Investig Clin Urol
January 2025
Department of Urology, College of Medicine, The Catholic University of Korea, Seoul, Korea.
Purpose: To evaluate the feasibility of robot-assisted ureteral reconstruction as a minimally invasive alternative to open surgery for managing ureteric complications in transplanted kidneys.
Materials And Methods: From January 2020 to December 2023, robot-assisted ureteral reconstruction was performed on fifteen kidney transplant patients with vesicoureteral reflux (VUR) or ureteral stricture who had previously failed endoscopic treatments.
Results: Twelve females and three males, with a mean age of 48.
The Macedo ileum-based reservoir for the management of bladder involvement in epidermolysis bullosa.

Department of Pediatric Surgery and Urology, Medical University of Silesia, ul. Medyków 16, 40-752, Katowice, Poland.
Introduction: Epidermolysis bullosa (EB) can severely affect the urinary tract, leading to strictures and urine outflow obstruction, which pose significant risks to kidney function. Procedures involving the urinary mucosa often exacerbate these issues, making safe bladder emptying a major challenge. This study reviews surgical methods for managing urological complications in EB patients, with a focus on the Macedo procedure, which offers a promising alternative that avoids further bladder mucosa irritation and prevents disease exacerbation.

Objective: To report the statistics of complications in gender reassignment surgery (vaginoplasty) observed in the first surgical center in Mexico for public transgender surgery.
Method: We conducted a descriptive, observational study of patients treated and postoperatively underwent vaginoplasty surgery in the period 2019 to 2022. Intraoperative, immediate and late complications were evaluated.
Decellularization of fish tissues for tissue engineering and regenerative medicine applications.

Decellularization is the process of obtaining acellular tissues with low immunogenic cellular components from animals or plants while maximizing the retention of the native extracellular matrix structure, mechanical integrity and bioactivity. The decellularized tissue obtained through the tissue decellularization technique retains the structure and bioactive components of its native tissue; it not only exhibits comparatively strong mechanical properties, low immunogenicity and good biocompatibility but also stimulates neovascularization at the implantation site and regulates the polarization process of recruited macrophages, thereby promoting the regeneration of damaged tissue. Consequently, many commercial products have been developed as promising therapeutic strategies for the treatment of different tissue defects and lesions, such as wounds, dura, bone and cartilage defects, nerve injuries, myocardial infarction, urethral strictures, corneal blindness and other orthopedic applications.

Urology Department, Ankara University Faculty of Medicine, 06480 Ankara, Turkey.
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.
