Introduction: Complex ureteral obstruction is a pathology that has always been a challenge for the urologist, especially in patients with high surgical risk or with a short life expectancy.
Material And Methods: Between 2002 and 2017, 13 extra-anatomical bypasses were placed. A descriptive retrospective study was carried out. An analysis of the permeability time of the prosthesis was performed using Kaplan-Meyer curves. Demographic and etiological characteristics as well as early and late complications were analysed.
Results: Etiologies were benign in 39% (including 3 transplant recipients) and malignant in 69%. Permeability rates were 90.9% at each of 12, 24 and 48 months, respectively, and 75.8% at 60 months. There were no deaths in the early postoperative period, nor intraoperative complications. The most frequent complications were infections. Three of them were associated with bypass extrusion, which needed to be removed. A total of 5 prosthesis had to be removed. 40% of the patients did not present complications.
Conclusions: The extra-anatomical ureteral bypass is an alternative to permanent nephrostomy in the treatment of complex ureteral strictures. Their patency rates after long-term follow-up vary from 90% to 75% at 48 and 60 months, respectively. Their complication rates can be considered acceptable in the patients' clinical contexts.

Purpose: To evaluate stone free rate (SFR) predictivity of three different scoring systems in patients with kidney stones larger than 20 millimeters undergoing retrograde intrarenal surgery(RİRS).
Methods: Digital records of a total of 166 patients were reviewed retrospectively. Epidemiological characteristics (age, gender, medical history) of the patients, stone and affected kidney characteristics (size, volume, location, density, opaque, presence of urinary system anomaly, presence of stones in different calyx, number of stones, lower pole stone, renal infundibulopelvic angle (IPA), renal infundibulopelvic length (RIL), hydronephrosis), and operative characteristics (preoperative ureteral stent, operation duration, postoperative residual fragments, hospitalization time and complications were recorded.

Introduction And Importance: While the treatment approach for sarcomas seems straightforward and well-defined, we often encounter several diagnostic or therapeutic challenges in clinical practice. This article presents a case of retroperitoneal leiomyosarcoma in a patient with chronic kidney disease, highlighting the complexity of managing such cases.
Case Report: A 63-year-old woman with a history of chronic kidney disease presented with a progressively enlarging mass in her right flank.

Background: Flexible ureteroscopy (FURS) is increasingly used as the first-line treatment for urological procedures. Disposable digital (dd-)FURS has been developed to overcome limitations such as durability, degradation, and repair cost of reusable scopes. The diameter of commercially-available models ranges from 7.

Department of Urology, Gemelli isola Tiberina Hospital, Rome, Università Cattolica del Sacro Cuore, Rome, Italy.
Introduction And Objective: Radical Cystectomy (RC) is one of the most common and complex surgical procedures in urologic surgery, and benign ureteroenteric anastomosis strictures (UAS) are complications described in about 15% of patients undergoing RC with different urinary diversion (UD). The aim of this study is to evaluate and analyze risk factors related to the development of ureteral stenosis after RC.
Materials And Methods: All consecutive patients who underwent RC with ileal conduit from December 2019 to December 2022 were included.
