[THREE CASES OF IATROGENIC URETERAL INJURY ASSOCIATED WITH TOTAL LAPAROSCOPIC HYSTERECTOMY].

We report three cases of iatrogenic ureteral injury associated with total laparoscopic hysterectomy. Case 1 was a 50-year-old woman. She underwent total laparoscopic hysterectomy (TLH) for myoma uteri. Postoperatively, a blood test revealed renal dysfunction, and ultrasonography (US) revealed left hydronephrosis. She was referred to our department on the next day of TLH. Computed tomography (CT) revealed left hydronephrosis. Retrograde pyelography (RP) was tried, but the ureteral catheter could not be inserted into the left ureteral orifice. An operation was performed on the second day after THL. The left ureter was ligated near the ureterovesical junction, and so uretero-ureterostomy was conducted. Case 2 was a 38-year-old woman. She underwent TLH for myoma uteri. Postoperatively, she complained of abdominal fullness and diarrhea. A blood test revealed renal dysfunction and US revealed left hydronephrosis on the ninth day after THL. She was referred to our department next day. CT revealed left hydronephrosis and ascitis. RP revealed extravasation of contrast medium from the left ureter. She was diagnosed with left ureteral injury accompanied by extravasation of urine into the intraperitoneal space. Uretero-cystoneostomy was performed. Case 3 was a 45-year-old woman. She underwent TLH for myoma uteri. Postoperatively, a blood test revealed renal dysfunction, and US revealed left hydronephrosis. She was referred to our department on the fifth day after TLH. CT revealed left hdronephrosis and ureteral obstruction of the left lower ureter. An operation was performed under laparoscopy, cystoscopy, and fluoroscopy on that day and the left lower ureter was kinked by threads. Cutting of the threads was performed under laparoscopy. After thread cutting, the kink of the ureter was improved and ureteral stent could be indwelled between the renal pelvis and bladder. After 1 month, the ureteral stent was removed and left hydronephrosis disappeared.
