Abstract

Introduction: Auto-expandable ureteral stents can be an alternative to percutaneous nephrostomy (PCN) in refractory ureteral stenosis. Our aim is to analyse results and complications of ureteral stents in our centre.

Methods: Retrospective review of OptiMed® expandable ureteral stents placed in our centre (1996-2022). Analysis of complications (Clavien-Dindo classification). Kaplan-Meier curves (long-rank test) to assess stent permeability and Cox regression for associated factors.

Results: 58 patients were included. Median follow-up: 36 months (11-82). Median age: 61 years (48-68). Most frequent aetiology of ureteral stenosis was malignancy in 30 cases (53.6%). The most common location of stricture was distal ureter in 44 (63.8%) ureteral strictures. Creatinine levels improved in 28(48.3%) cases. Most common acute complication was UTI in 6(3.4%) patients (Clavien-Dindo II). 20 patients presented with stent obstruction. 14(24.1%) were solved with double J stenting and 6(10.3%) cases with PCN. Mean stent survival time was 50 months (34.3-65.8). By the end of follow up, 23(39.6%) patients were alive. Of those, 9(39.1%) had a functioning stent. No association of any factor with patency of stent was found.

Conclusions: Expandable ureteral stents are an alternative to PCN in fragile patients with refractory stenosis, which offers a better quality of life.

期刊介绍： Concise but fully substantiated international reports of clinically oriented research into science and current management of urogenital disorders form the nucleus of original as well as basic research papers. These are supplemented by up-to-date reviews by international experts on the state-of-the-art of key topics of clinical urological practice. Essential topics receiving regular coverage include the introduction of new techniques and instrumentation as well as the evaluation of new functional tests and diagnostic methods. Special attention is given to advances in surgical techniques and clinical oncology. The regular publication of selected case reports represents the great variation in urological disease and illustrates treatment solutions in singular cases.
