Transient large urinoma following hysterectomy.

This case report describes the formation of a very large urinoma 1 day after vaginal surgery. A 59-year-old woman was diagnosed with a urinoma measuring 30.5 cm in length, 23 cm in the transverse plane and 12 cm in the anteroposterior dimension on day 1 after a vaginal hysterectomy and prolapse repair surgery. The urinoma resolved completely after trans-abdominal catheter drainage. This case demonstrates that even a large urinoma can initially be managed conservatively. Furthermore, it emphasizes the importance of the early detection and management of urinary tract injuries after vaginal surgery.
