The purpose of the study was to investigate feasibility of retrograde intrarenal surgery (RIRS) in patients with isolated anomaly of kidney rotation with kidney stones. We retrospectively reviewed the medical records of patients who underwent RIRS due to kidney stones in three referral hospitals. Twenty-four patients who had kidney rotation were included in this study. The patients with horseshoe kidney or pelvic kidney were not included in the study. The patients were evaluated for final success 1 month after surgery. Success was defined as stone-free or fragment smaller than 3 mm. Mean age of patients was 39.5 years (1-71 years) and male/female ratio was 3:1. Mean stone size was 13.46 mm (5-30 mm). Twelve (50 %) patients had the operation on the right side and other 12 (50 %) patients had on the left side. Eighteen (75 %) patients were stone-free after single procedure. And stone-free rate increased to 83.3 % after additional treatment procedures. When we compared the successful and failed procedures, gender, stone side and size, preoperative hydronephrosis, access sheet usage, ureteral double-J stent insertion were not statistically significant in two groups. We did not confront major complication. RIRS seems to be an effective and safe treatment option for renal stones in patients with isolated anomaly of kidney rotation.
