Abstract:
Objective To investigate the main causes and strategies for the difficulties in ureteroscopic lithotripsy.Methods From March 2004 to December 2006,19 cases of ureteral calculi,who experienced difficulties during holmium laser lithotripsy or pneumatic lithotripsy under a rigid ureteroscope,were analyzed retrospectively.Among the cases,3 had difficulties in ureteroscope placement due to the narrow ureteral ingress,6 owing to calculus obstruction complicated with ureteral inflammatory polypi,4 resulted from twisted ureter,and 6 because of stenosis of the ureter.Results In 15 of the patients,the operation was successfully performed by changing surgical approach,controlling the hydraulic irrigation,and incising the stenotic segments,etc.Two patients,who had stenotic ureter,received ESWL with double-J catheter dwelling.Lithotripsy failed in 2 cases,and PCNL was used to remove the calculi.The postoperative complications occurred in 4 cases,including 2 with mucosal laceration and 2 ureteral perforations.One of the 4 cases was transferred to an open surgery,and the other 3 were cured by conservative treatments.Conclusions Holmium Laser lithotripsy and pneumatic lithotripsy under a rigid ureteroscope are safe and effective in treating ureteral calculi.
