A woman in her mid-60s with history of uterovaginal prolapse, status post hysterectomy, was incidentally noted to have a patent urachus at the bladder dome on cystourethroscopy. A CT scan showed a partially distended urinary bladder with a small vesicourachal diverticulum and focal calcifications at its apex. Partial cystectomy with excision of the entire urachus was performed. Gross examination showed a 3.2 cm cystic nodule with calcified cut surface. Images from the partial cystectomy are shown below.
