Objective: To evaluate the prevalence and the risk factors of the ureteral stricture following renal transplantation and outcomes of surgical managements.
Methods: By a retrospective analysis, we assessed 1 293 patients who underwent renal transplantation between January 2001 and December 2013 at our center. The patients with ureteral stricture had undergone surgical management which included neoureterocystostomy, ureteral anastomosis with the native ureter and endoscopic therapy.
Results: Ureteral stricture following renal transplantation was diagnosed in 17 cases (1.3%) including 6 males and 11 females. The mean age of the patients at the time of surgery was 44 (29 to 64) years. The median interval between ureteral stricture obstruction and kidney transplantation was 4 (1 to 120) months. The ureteral stricture was significantly correlated with multiple renal arteries, donor age and delayed graft function. The effective rate of surgical management was 65.75%.
Conclusion: The incidence of ureteral stricture as a urologic complication after renal transplantation is low. The advanced techniques that preserve the ureteric blood supply should be applied. The surgical managements have respective advantages and disadvantages. The neoureterocystostomy shows best outcome, while ureteral anastomosis with the native ureter has poor outcome.

Background And Objective: Management of a long proximal ureteral stricture is challenging. Buccal mucosal graft (BMG) ureteroplasty is a reliable technique for ureteral reconstruction that avoids the morbidity of bowel interposition or autotransplantation. We compared open and robotic BMG ureteroplasty in a two-center study.

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.

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.
A Technique for the Internalization of Nephroureteral Stents in Patients With Ileal Conduits.

Department of Interventional Radiology, St James's Hospital, Dublin, IRL.
We present a method of internalization of nephroureteral stents to internalized ureteral stents in a patient with an ileac conduit urostomy with radiation-induced ureteral strictures, and recurrent urinary tract infections (UTIs). This technique is applicable to patients requiring internalization of nephroureteral stents in the setting of an ileal conduit, emphasizing patient consent, preparation, position, imaging guidance, and antibiotic prophylaxis. The successful application of this technique offers a practical solution for managing recurrent UTIs in patients with similar medical histories, providing both clinical and procedural insights.
