Comparative study on ureteroscopic lithotripsy and laparoscopic ureterolithotomy for treatment of unilateral upper ureteral stones.
Acta Cirúrgica Brasileira 2012 March
PURPOSE: To compare the curative effects of ureteroscopic lithotripsy and laparoscopic ureterolithotomy for unilateral upper ureteral stones, and to explore optimal surgical indications and skills.
METHODS: Fifty cases of unilateral upper ureteral stones were randomly divided into two groups: one group underwent ureteroscopic holmium laser lithotripsy under epidural or lumbar anesthesia (n=25), and another group underwent laparoscopic ureterolithotomy under general anesthesia (n=25). Double-J stent was routinely indwelled in both groups. Operating time, postoperative hospitalization time, stone clearance rate and perioperative complications were compared.
RESULTS: Operation was successfully performed in all 50 cases, and no open surgery was converted in any case. In the ureteroscopy and laparoscopy groups, the mean operating time was 49.0 ± 10.7 min and 41.8 ± 8.0 min (t=2.68, P=0.00999), respectively, their hospitalization time was 2.8 ± 1.3 days vs. 2.9 ± 0.8 days (t =-0.40, P=0.69413), and stone clearance rate was 88.0% (22/25) vs. 100% (25/25). Stone moved to the renal pelvis in three cases in the ureteroscopy group, and residual stones were removed by extracorporeal shock-wave lithotripsy (ESWL). All patients were followed up for more than three months, and no serious complications such as ureterostenosis occurred.
CONCLUSIONS: Laparoscopic ureterolithotomy has a higher stone clearance rate and shorter operation time compared with ureteroscopic lithotripsy. Laparoscopic ureterolithotomy is one safe and effective treatment on unilateral upper ureteral stones.
