Aim: We aimed to evaluate extracorporeal shock wave lithotripsy (ESWL) success rate performed on patiens with renal and ureteral stones in a provincial hospital. Material And Method: 611 patients who have been treated with extracorporeal shock wave lithotripsy (ESWL)due to renal or ureteral stones between December 2009 – February 2014 evaluated retrospectively. Mean age was 42.4 (17-79) years. Extracorporeal shock wave lithotripsy was applied for 395 kidney stones and 216 ureteral stones. The percentage of the localization of stones in the urinary tract treated by ESWL were as follows: 15.87, 17.02, 3.43, 28.31, 24.38, 9.49, and 1.30 percent in upper caliceal, middle caliceal, lower caliceal, renal pelvis, upper ureteral, mid ureteral, and lower ureteral respectively. The stones were focused by a C-armed floroscopy. Average shock number was 3600 (1500-5000) and average voltage was 18 (14-22) kV for each case. Totally 1312 extracorporeal shock wave lithotripsy sessions were performed to 611 patients, each case was subjected to average 2.14 ESWL sessions. Findings: In 3 weeks follow-up; 88.14, 75.62,and 42.10 percent of the patients with less than 10 mm, between 10 mm and 20 mm, larger than 20 mm urinary stones were stone-free, respectively. upper caliceal, middle caliceal, lower caliceal, renal pelvis, upper ureteral, middle ureteral calculi and lower ureteral were stone-free in 78.35, 77.88, 61.90, 79.76, 80.53, 81.03, and 55.55 percent of the patients, respectively. The success rate at lower caliceal stones of kidney, lower end stones of uretery and stones with dimensions over 20 mm (free of location) were low. Our success rates at upper calyx, mid calyx, upper ureter, mid ureter stones and stones with dimensions below 20 mm (free of location) are similar to literature. Conclusion: Our data show that success rates which are similar to those reported in literature could be achieved in a provincial hospital with convenient indications and experienced technician.
