Flexible ureteroscopy combined with potassium sodium hydrogen citrate(PSHC) intervention improves the stone-free rate(SFR) for 20-30 mm uric acid renal stones.

ABSTRACT:

Objective

To evaluate the efficacy and safety of combining flexible ureteroscopy (FURS) with potassium sodium hydrogen citrate(PSHC) for the treatment of 20-30 mm uric acid renal stones.

Methods

A retrospective analysis of outcomes of patients with 20-30 mm uric acid renal stones who were treated with FURS and holmium lithotripsy was conducted between July 2021 and May 2024. Of them, 60 patients accepted FURS combined potassium sodium hydrogen citrate(PSHC) therapy while 70 patients underwent the FURS procedure alone. The demographic data, stone characteristics, surgical details, and perioperative outcomes of the patients were assessed retrospectively. Stone-free status was defined as the complete absence of stones on computed tomography.

Results

Totally 130 patients
