Abstract:
Objective To explore the underlying clinical factors and precautionary measures of fluid extravasation in patients with calyceal calculi treated by ureteroscopic holmium laser lithotripsy.Methods A retrospective review was made on clinical records of 138 patients with calyceal calculi receiving retrograde ureteroscopic holmium laser lithotripsy from May 2005 to March 2009. The relevance was studied between the occurance of fluid extravasation complications and various clinical factors using x2 test and binary Logistic regression. The clinical factors included patients' sexes, age groups (＜30 years, 30-50 years, ＞50 years), history of treatment (ESWL or open surgery) for upper urinary tract calculi, preoperative upper urinary tract infection, intraoperative placement of ureteral catheter and the length of procedure duration (＜ 50 min, 50-80 min, ＞ 80 min). Results Fluid extravasation complications occurred in 24 patients. The sexes and age groups were irrelevant to the occurance of fluid extravasation complications; while history of ESWL or open surgery and preoperative infection in upper urinary tract, without intraoperative ureteral catheter placement and long duration of procedure were responsible for the higher rates of the fluid extravasation complications.Conclusion Reasonable selection of patients and timing of operation, regular intraoperative ureteral catheter placement and control the length of procedure duration help to reduce fluid extravasation during retrograde ureteroscopic lithotripsy.
