 Case Report

A 50-year-old lady who had undergone vaginal hyster­ectomy for prolapse uterus, developed urine leak per vaginum two weeks after surgery which subsided after a few days. Subsequently she started passing clear fluid per rectum along with normal voiding. Urine culture revealed a heavy mixed bacterial growth. Renal function tests in­cluding electrolyte estimations were normal. Ultrasonog­raphy showed right-sided hydroureteronephrosis without any mass or fluid collection in the pelvis. An intravenous urogram showed a right-sided hydroureteronephrosis and normal bladder with contrast entering the sigmoid colon and rectum, confirming the diagnosis of ureteroenteric fis­tula [Figure 1],[Figure 2]. Cystoscopy revealed normal bladder mucosa with absence of ureteric efflux on the right side. The site of fistula above the rectosigmoid junction could be visualised on sigmoidoscopy. On exploratory laparo­tomy, the dilated right ureter could be traced to the site of fistula above the rectosigmoid junction. A left-over broad ligament fibroid was dissected out and excised. The ure­ter was divided at the site of fistula, the distal end ligated and proximal end reimplanted into the bladder. The pa­tient had an uneventful postoperative period with no rec­tal or vaginal urine leak. Relief of obstruction to right kidney was demonstrated on follow-up ultrasonography.


Ureteral injury is less common during vaginal hyster­ectomy than abdominal hysterectomy with an overall re­ported incidence varying from 0.5-3%. [1] Ureteroenteric fistula is a rare occurrence usually caused by inflamma­tory bowel disease or surgical procedures in the presence of infection, malignancy, hematoma or prior radiation. [2] Uretero-sigmoid fistula following vaginal hysterectomy has not been reported so far. In the above case, it may be attributed to a difficult vaginal hysterectomy due to the presence of dense adhesions in the parameterium causing excessive bleeding during dissection, distortion of anatomy by the broad ligament fibroid and a long redundant loop of sigmoid colon forming an enterocoele, leading to inad­vertent ureteric and sigmoid injury ultimately resulting in a uretero-sigmoid fistula.
