Abstract
OBJECTIVE: To evaluate patients' characteristics, surgical procedure data, and outcomes of ureterorenoscopy (URS) stone treatment in patients with a horseshoe kidney (HSK), ectopic kidney (EK), and malrotated kidney (MK). MATERIALS AND METHODS: This study is a subanalysis of the Clinical Research Office of the Endourological Society URS Global Study, which was a prospective multicenter observational study, collecting data on URS stone treatment from consecutive patients over a 1-year period. A total of 114 centers in 32 countries participated. This analysis acuminated on URS stone treatment in the specified renal anomalies: HSK, EK, and MK. For each group, patient characteristics, operation data, and treatment outcomes were evaluated. RESULTS: Of the 11,885 patients included in the Clinical Research Office of the Endourological Society URS study, 43 patients had HSK, 27 EK, and 16 MK. The stone-free rate (SFR) in the HSK group was 77% for renal stones and 85% for ureteral stones. In the HSK group, the intraoperative complication rate was 11.6% and the postoperative complication rate was 7%, including 1 Clavien grade IIIa and 1 IIIb complication. In the EK group, the SFR was 20% for renal stones and 94% for ureteral stones, with an intraoperative complication rate of 14.8% and a postoperative complication rate of 7.4%. One Clavien IVa complication was reported. In the MK group, the SFR was 71% for renal stones and 88% for ureteral stones, with an intraoperative complication rate of 6.3%. No postoperative complications occurred in this group. CONCLUSION: URS is an effective and safe treatment modality to remove ureteral and renal stones in patients with HSK and MK. The effectiveness of URS for renal stones in EK was low.
