Entero-urinary fistulas are uncommon in urological practice and may have widely varying aetiologies ranging from benign to malignant or iatrogenic in nature. All permutations of entero-urinary fistulas have been reported in the literature except an appendico-renal fistula. Here, we present one such case, presenting with urinary tract infections and perineal urethrocutaneous fistulae. He was ultimately diagnosed to have a spontaneous appendico-renal fistula as underlying pathology behind the symptoms.
