Prevention and Treatment of Early Complications of Ureteroscopy and Pneumatic Lithotripsy / 中国微创外科杂志

ABSTRACT

Objective To summary our experiences on the clinical management of early complications caused by ureteroscopy and pneumatic lithotripsy. Methods From May 2002 to December 2007,totally 660 patients received ureteroscopy and pneumatic lithotripsy in our hospital,25 of them had surgical complications. Their clinical data were analyzed retrospectively. Results Among the 25 cases,22 patients had ureteral perforation,2 had ureteral disruptions,and 1 showed pelvic hematoma owing to ureteral perforation and injury to the ovary vein. Of the 22 cases of ureteral perforation,13 patients received lithotripsy and placement of a double J stent into the renal pelvis via the perforation site;and 4 patients underwent repair of the ureter. The other 5 of the 22 cases refused open surgery,and showed symptoms of urinary extravasation,loin pain,fever,or hematuria postoperatively;PCN was successfully completed in 3 of them but failed in the other 2,who underwent open surgery afterwards. For the 2 patients with ureteral disruptions,ureteroureteral anastomosis was performed. And in the case of pelvic hematoma,we carried out open surgery to ligate the bleeding vessels. All of the 25 patients were cured and discharged from hospital prosperously. The double J stent was withdrawn in 2 months after the operation,and 1-year follow-up showed no ureteral stenosis or obstruction by intravenous pyelography. ConclusionsPrimary management of ureteral injury by indwelling double J stent or percutaneous nephrostomy results in significantly deceased rate of re-operation. Conversion to open surgery timely can stop the incidence of other severe complications.
