Patients and methods82 patients with proximal ureteric stones were included and were divided into two subgroups where UWT was >5 mm in 38 cases; and <5 mm in 44 cases. Stone size, degree of hydronehrosis, diameter of proximal ureteral lumen, UWT and patient's demographics were evaluated. Semi-rigid ureteroscopy with Ho-YAG laser was performed and the possible impact of UWT as an objective parameter for stone impaction on the success rates and procedure related parameters was evaluated. ResultsMean patient age and stone size values were 47.55 ± 1.78 years and 8.17 ± 0.29 mm respectively. Regarding the impact of UWT value at the stone site for the parameters mentioned above stone free rates particularly at 1-week after the procedure was higher in group 2 and the rate of residual fragments as well as the need for double J stent placement was higher in group 1. Additionally, mean duration of the procedures was significantly longer in Group 1 during which pathologic alterations were significantly higher in ureteral wall at stone site were observed in these cases (p:0.0243). ConclusionsUWT may be used to predict the success of ureteroscopic management and other procedure related parameters for proximal ureteral stones in an effective manner. With this approach a more rational operative plan with higher success rates, limited complications and auxiliary procedures could be made. ER -
