Comparing Bendable Tip-Suction and Conventional Ureteral Access Sheaths During Retrograde Intrarenal Surgery to Treat Staghorn Kidney Stones

What this Trial Is About

This research aims to compare the safety and effectiveness of two types of ureteral access sheaths used during retrograde intrarenal surgery RIRS for managing staghorn renal stones. Staghorn renal calculi are complex kidney stones that fill the renal pelvis and branch into the kidneys calyces. Although percutaneous nephrolithotomy is the standard treatment, RIRS is a less invasive option increasingly used, especially for patients unsuitable for the traditional approach. The study evaluates whether a new bendable tip-suction sheath improves surgical outcomes compared to a conventional sheath. Participants will undergo retrograde intrarenal surgery using either a bendable tip-suction ureteral access sheath connected to a suction system or a conventional ureteral access sheath. The bendable sheath is designed to reach targeted kidney areas more effectively, maintain a clear view by continuous suction, and remove stone fragments during laser lithotripsy. The study randomly assigns patients to one of these two groups to assess differences in safety and efficiency. During the study, patient safety will be monitored from surgery through one month afterward to evaluate the surgical techniques safety. The effectiveness of the surgery will be measured one month post-operation. Participants will be assessed with renal function tests and followed for any complications, with data collected on surgical outcomes and recovery. The total participation duration includes the surgery and follow-up period of at least one month.
