UNASSIGNED: To determine the safety and efficacy of modular flexible ureteroscopy and holmium laser lithotripsy for the treatment of @entity1290 , a retrospective chart review of a single surgeon's 3-year modular flexible ureteroscopy experience was performed. All of the @entity1 were treated with modular flexible ureteroscopy and holmium laser lithotripsy by a single surgeon. Stone-free status was defined as no fragments or a single fragment  <=4 mm in diameter at the 3-month follow-up. The procedure number, operative time, stone-free rates, repeat usage of the multilumen catheter, and perioperative complications were documented. The present study included 215 male @entity1 and 167 female @entity1 , with an average age of 48.5  13.7 years (range, 17-84 years). The mean stone size was 11.5  4.1 mm (range, 4-28 mm), and the mean total stone burden was 17.5  5.7 mm (range 15-46 mm). A total of 305 @entity1 (79.8%) had a stone burden  <=20 mm, and 77 @entity1 (20.2%) had a stone burden >20 mm. The mean number of primary procedures was 1.3  0.2 (range, 1-3). The stone-free rate following the first and the second procedure was 73.4 and 86.9%, respectively. The mean postoperative hospital stay was 3.1  1.2 days (range, 2-6 days). The highest clearance rates were observed for proximal ureteral stones (100%) and renal pelvic stones (88.7%), whereas the lowest clearance rates were observed for lower calyx stones (76.7%) and multiple calyx stones (77.8%). The higher the initial stone burden, the lower the postoperative stone-free rate ( <=20 vs. >20 mm; 89.8 vs. 75.3%). The overall complication rate was 8.1%. The results of the present study suggest that modular flexible ureteroscopy with holmium laser lithotripsy may be considered the primary method for the treatment of @entity1290 in select @entity1 , due to its acceptable efficacy, low morbidity, and relatively low maintenance costs.
