Comparison Between Ureterorenoscopy With Lithotripsy Alone Versus Combination With Hydrogel for Kidney Stone Removal

The patient provides written informed consent and is positioned in the supine position. After disinfection, sterile draping, and single-shot antibiotic administration a rigid cystoscopy is performed. Intubation of the ostium with a hydrophilic guidewire and placed into the renal pelvis under fluoroscopic control. After a semirigid URS, a working sheath is placed up to the Kidney. A flexible URS with lithotripsy with a Thulium lase is then performed to dust the stones. The fragments are retrieved for analysis. Finally, a double-J or mono-J stent and a transurethral catheter are placed.
