Summary
Brief summary
Background: The exit strategy after ureteroscopy for stone treatment remains a topic for
discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is
indicated in patients at increased risk of postoperative complications. Stenting is not
considered necessary in all other cases, and after uncomplicated procedures.
Objective: To analyse the postoperative ureteral stenting strategy in clinical practice
looking at the indication, type of stents used and the duration of stenting after
ureteroscopy for stone treatment. Furthermore, the investigators will examine in what setting
the stents are being removed postoperatively.
Study design: This study is a prospective, observational, international, multicentre registry
study executed by uCARE.
Study population: All patients >18 years with a ureter or renal stone who are planned for
ureteroscopic treatment by semi-rigid and/or flexible ureteroscopy are eligible for this
study.
