Flexible ureteroscopy for renal stone without preoperative ureteral stenting shows good prognosis.

ABSTRACT:

Purpose

To clarify the outcome of flexible ureteroscopy (fURS) for management of renal calculi without preoperative stenting.

Methods

A total of 171 patients who received 176 fURS procedures for unilateral renal stones were reviewed. All procedures were divided into two groups depending on whether they received ureteral stenting preoperatively. Baseline characteristics of patients, stone burden, operation time, stone-free rates, and complications were compared between both groups.

Results

Successful primary access to the renal pelvis was achieved in 104 of 114 (91.2%) patients without preoperative stenting, while all procedures with preoperative stenting (n = 62) were successfully performed. A total of 156 procedures were included for further data analysis (56 procedu
