The Feasibility of Semi-rigid Ureterorenoscopy in Small Sized Renal Pelvic Stones

Abstract

Introduction: In this retrospective study, we aimed to present the comparison of small-sized renal pelvis stones of patients whom were treated by either semi rigid ureteroscope (S-URS) or ESWL. Materials and Methods: Between March 2011 and 2013, 24 patients were treated with S-URS for renal pelvic stones. 33 patients treated by ESWL with similar parameters were included in the study as the control group. Results: The mean age and size of stones were similar in both groups. The success rates were 91.7% in Group 1, and 93.9% in Group 2 (p=0.224). The hematuria rates in the postoperative first day were 75% in Group 1, and 3% in Group 2 (p=0.01). Conclusion: While the success rates were similar for both groups, the hematuria rate was higher in S-URS group.
