A 69-year-old man, who had undergone hernioplasty for a right inguinal hernia at the ages of 57 and 64 years, presented to our hospital with a 6-month history of a right inguinal bulge. Abdominal computed tomography (CT) showed a soft-density mass in the right groin that contained part of the urinary bladder. Thus, a right inguinal hernia with bladder herniation was diagnosed, and transabdominal preperitoneal repair (TAPP) was performed. The patient's postoperative course was uneventful, and he was discharged from our hospital on postoperative day 2. There have been no signs of recurrence. There have been 17 reports of the TAPP method for bladder hernia repair in Japan. CT is considered a useful diagnostic method for a bladder hernia. A preoperative diagnosis of bladder hernia is important to prevent intraoperative bladder injury. A re-recurrent case of inguinal bladder hernia that was treated by transabdominal preperitoneal repair is presented.
