Live ascaris in urinary bladder: a case report

INTRODUCTION: Ascaris in urinary bladder is an extremely rare phenomenon. It may occur after fistula formation between urinary and gastrointestinal tract or by retrograde migration of adult worm, and is associated with complications. CASE PRESENTATION: A 47-year-old Amhara woman from rural northwest Ethiopia presented with a complaint of difficulty to fully evacuate her bladder of 1 year duration. Ultrasonography showed thickened bladder wall with echo debris. There were also thickened bowel and fluid-filled loops of intestine adjacent to urinary bladder. On cystoscopy examination, there was live ascaris swimming inside the bladder. Enterovesical fistula was entertained and explorative laparotomy performed. Findings confirmed presence of iliovesical fistula. The fistula was divided and the continuity of the intestine restored. The inflammatory mass was subjected to histopathology study and turned out to be benign inflammatory reaction. She was also given antihelminthics. Postoperatively, her course was uneventful, and she was discharged cured. CONCLUSION: Though it is extremely rare to have urinary symptoms from ascariasis, it is important to have a high index of suspicion for all possibilities.
