Abstract
Objective: Multiple kidney stones are seen in 20-25% of the patients. Treatment of multiple kidney stones is challenging. Retrograde intrarenal surgery is used in the treatment of multiple kidney stones. Success is lower than the single stones of the same size. We aimed to report our retrograde intrarenal surgery experience in the treatment of multi-caliceal and multiple kidney stones.
Material and Methods: After approval of local ethics committee, patient data between 01.01.2014-01.01.2019 were retrospectively analyzed. Patients who had undergone retrograde intrarenal surgery for multi-caliceal and multiple kidney stones were included in our study. Demographic, intraoperative and postoperative data and complications were recorded.
Results: Forty-three patients were included in our study. The mean stone size was 13.69±6.21 mm.
Mean stone volume was 972.48 ± 905.24 mm3. Mean Hounsfield unit was 1128.26±317.91 HU. The mean operation time was 51.97±20.18 minutes. Thirty-two patients were stone free. Postoperative complications were seen in four patients. Mucosal injury was observed in one patient and urinary tract infection was observed in three patients.
Conclusion: Multi-caliceal and multiple kidney stone treatment is challenging for urologists. There are various treatment methods. Retrograde intrarenal surgery is a safe and efficient alternative for the treatment of multi-caliceal and multiple kidney stones. Prospective and larger cohort studies are needed.
