The success of extracorporeal shock wave lithotripsy at stones up to 10 mm in horseshoe kidneys

Aim of this study is to research retrospectively the effectiveness of extracorporeal shock wave lithotripsy (SWL) for horseshoe kidney according to the size of stones. SWL treatment applied on 27 kidney stones in 21 patients at a single center were examined retrospectively. Stones were classified according to their size, the number of shock waves applied and average session number. The mean age of the patients was 44 (18-70). Stone sizes were 16mm (7-40) X 10mm (5-30). Average of sessions was 2.55 (1-3) and shock number was 1643 (977- 2300). The success rate of SWL treatment at horseshoe kidney stones which were under 10 mm was 90% and for over 10 mm it was 30% (p=0.001). Success rates were detected 63%, 52% and 48%; respectively up to 0-15 mm, 0-20mm and for all stones. The SWL success rate with horseshoe kidney is similar to that in normal kidney. The success rate decreases as stone size increases. SWL is a safe and effective treatment option for horseshoe kidney stones. Especially for stones up to 10 mm, the rate of SWL's success rate is pretty high. [Med-Science 2016; 5(3.000): 767-70
