A Comparative Study of Retrograde Intrarenal Surgery versus Percutaneous Nephrolithotomy for the Management of Staghorn Renal Calculi.

Aim: The indications for performing retrograde intrarenal surgery (RIRS) have increased. However, no comparative studies have been conducted on the treatment of staghorn renal calculi using RIRS and percutaneous nephrolithotomy (PCNL). We aimed to compare the effectiveness and safety of RIRS and PCNL as treatments for staghorn renal calculi.

A comparative study of flexible ureteroscopic lithotripsy for upper urinary tract stones in patients with prior urosepsis following emergency drainage via retrograde ureteral stent or percutaneous nephrostomy.

Background: Patients with urosepsis associated with upper urinary tract stones require further stone management after emergency drainage.

Objective: To evaluate the safety and efficacy of elective flexible ureteroscopic lithotripsy (F-URSL) for upper urinary tract stones in patients with prior urosepsis who have undergone emergency drainage using retrograde ureteral stent(RUS) or percutaneous nephrostomy (PCN).

Method: Between January 2017 and December 2021, clinical data were collected for 102 patients who underwent elective F-URSL following emergency drainage for urosepsis caused by upper ureteral or renal stones.
