Treatment of Complicated Pelvic Cystic Echinococcosis with Ureteral Stenosis

Echinococcus cysts are found mostly in the liver and lung, but they can occur in any parts of the body. However, complicated pelvic echinococcosis is seen in China. We report cases of nine complicated echinococcal cysts with ureteral stenosis localized in the pelvis. These cases were diagnosed preoperatively by color Doppler ultrasound and computed tomography or magnetic resonance imaging. We pre-placed the double “J” tube 1-7 days before surgery, which improved the renal function of the patient, and at the same time used the double “J” tube for directional navigation during surgery to avoid ureteral injury. All patients were successfully treated and recovered, then discharged. The results showed that preimplantation of a ureteral double “J” tube before ureteral stenosis effectively prevented ureteral injury and reduced the occurrence of complications.
