Crossed-fused renal ectopia (CFRE) is a rare congenital anomaly where both kidneys are fused on the same side. We report a case of a 52-year-old male patient who presented with central abdominal pain associated with hematuria and dysuria, with a history of left open ureterolithotomy. Abdominal computed tomography (CT) showed an 18-mm left distal ureteric stone and a CFRE with a bilateral duplex-collecting system. Left ureteroscopy and laser lithotripsy with magnetic double-J stent insertion were carried out successfully, and the patient was discharged on the same day in fair general condition.

Purpose: To compare stone clearance and complications between a 'wide' (9 × 50 mm) and 'narrow' shockwave focus (6 × 28 mm) when undertaking shockwave lithotripsy (SWL) in patients with renal or ureteric stones.
Methods: Data from patients undergoing SWL using the dual focus Storz Modulith SLX-F2 lithotripter at a single centre were prospectively collected between February 2018 and September 2020. Patients were matched by stone size, location, and number of treatments.

Purpose: Use of suction in flexible ureteroscopy is increasing lately. The introduction of flexible and navigable suction access sheath (FANS) has shown improved stone free rate (SFR). However, its efficacy in lower pole stone (LPS) in terms of SFR and complications is yet to be studied.

Purpose: The purpose of this study was to assess the feasibility of a pressure-controlled and temperature-controlled flexible ureteroscope system (PT Scope™) during flexible ureteroscopy.
Materials And Methods: We developed the PT Scope™, a novel ureteroscope system with capabilities for monitoring and controlling intrarenal pressure and temperature to maintain them within set parameters. Data were retrospectively collected from 48 consecutive patients diagnosed with upper urinary tract stones who underwent flexible ureteroscopic lithotripsy using the PT Scope™ across five centers in China.

Objective: The aim of this study was to compare the success and complication rates of retrograde intrarenal surgery for lower calyceal renal stones performed with novel tip-bendable suction ureteral access sheaths and standard ureteral access sheaths.
Methods: Between March 2023 and March 2024, a total of 88 patients underwent retrograde intrarenal surgery for lower renal calyceal stones smaller than 20 mm. Based on the access sheath used, patients were divided into two groups: Group 1 (n=43) included patients treated with novel tip-bendable suction ureteral access sheaths and Group 2 (n=45) included patients treated with standard ureteral access sheaths.

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.
