Is Ureteral Stenting Necessary After Uncomplicated Ureteroscopy Lithotripsy for Small Middle and Distal Ureteral Stones?
INTRODUCTION: Previous studies have suggested that routine stenting can be avoided following ureteroscopy. A prospective investigation was performed to determine the outcome of stent or no-stent placement after uncomplicated ureteroscopic lithotripsy for small (< 10 mm) middle and distal ureteral stones.
METHODS: Fifty six patients meeting inclusion criteria underwent uncomplicated ureteroscopic intracorporeal lithotripsy using a pneumatic device. No patient required ureteral dilation. Patients were randomly assigned to nonstented (n = 28) and stented (n = 28) treatment groups. The stent was removed after 2 days. Patients were followed for 2 weeks postoperatively.
RESULTS: There were no significant between-group differences in patient age, sex, stone size, or stone location. There were no significant between-group differences in mean operation time and postoperative pain. The group receiving the stent had a significantly longer mean hospital stay (2.14 days vs 1.25 days) (P < .0001). The stone-free rate was exactly the same at 96.4% for each group; the procedure was not successful for 1 patient in each group. There were no significant between-group differences in flank pain, fever, and hematuria. However, dysuria was significantly more common in the group receiving a stent (P = .002).
CONCLUSIONS: Patients who did not receive a stent after ureteroscopic intracorporeal lithotripsy had the same success rates as those who received a stent, while needing a shorter hospital stay and having less dysuria. These findings suggest that ureteral stent placement following uncomplicated ureteroscopy may be avoided, thereby reducing patient morbidity and surgical costs.
