Abstract

Objective: It is known that ESWL can promote acute renal injuries and long–term complications of renal vasculature. Effects on renal vasculature can be evaluated by color Doppler ultrasonography measuring renal resistive index (RI). This prospective study aimed to determine the influence of number of delivered SW-s, used kV and changes in renal resistive index. Patients and Methods: Total of 60 normotensive patients, 38 males (63%) and 22 females (37%), with renal stones 6-18 mm in size were included in this study. Median age was 42.3 years (range 22-55). RI was measured at interlobar artery before, 1, 3, 5 and 30 days after treatment on treated and contra lateral non-treated kidney. Patients were divided in two groups: Group I (N=25) received 2000SWs; 0-2 units; (0,5 unit each 500SWs) Group II (N=35) received 4000SWs, 0-4 units; (0,5 unit each 500SWs). Results: In treated kidneys RI significantly increased first and second day after treatment from 0,62±0,05 at baseline to 0,67±0,05, p
