Abstract:
Objective To evaluate the efficacy and safety of double-J stents in extracorporeal shock wave lithotripsy for the treatment of middle and upper ureteral calculi, and to explore the reasonable application of double-J stents. Methods 511 patients with middle and up-per ureteral calculi in our hospital were selected as the statistical objects. 161 patients of the catheter group were indwelled double-J stent be-fore extracorporeal lithotripsy while the other 350 patients in the no-catheter group underwent extracorporeal shock wave lithotripsy directly. The satisfaction rate of X-ray display location, gravel effect, and rate of adverse reaction were compared. Results The satisfaction rate of X-ray display location in the catheter group was higher than the no-catheter group (P=0. 025). And the gravel effect of the two groups were of statistical significance (P=0. 041). The incidence of hematuria and lower urinary tract symptoms in the catheter group was significantly high-er than that in the no-catheter group (P<0. 05). The incidence of renal colic in catheter group was lower than that in no-catheter group (P=0. 001). Conclusion Indwelling double-J stents is useful for stones display and localization, and it can improve the stone clearance rate. For ureteral stones whose diameter were less than 1 cm, double-J stents has little influence on the rate of stone clearance, but it can reduce the occurrence of severe renal colic.
