A 78-year-old man who had undergone McVay repair for bilateral inguinal hernias 14 years previously presented to our hospital with a right groin mass. Abdominal computed tomography (CT) showed that a part of the bladder had prolapsed caudal to the inguinal ligament and medial to the femoral vein. A diagnosis of femoral hernia involving the bladder was made, and a laparoscopic transabdominal preperitoneal repair procedure was performed. The laparoscopy also revealed that the bladder was inserted into the femoral ring. The preperitoneal space was dissected toward the space of Retzius to avoid damaging the bladder. Subsequently, with retraction of the hernial sac, the bladder was returned to its correct position. The postoperative course was good, and the patient was discharged from the hospital on the second postoperative day ; no recurrence or symptoms were noted at the 12-month follow-up. Most bladder hernias occur as direct inguinal hernias, and rarely develop as femoral ones. Preoperative diagnosis is often difficult, and bladder injury can occur due to the difficulties involved in reduction. We were able to safely repair the bladder using a laparoscopic procedure, although dissection along anatomical landmarks is important to prevent bladder injury in such cases.
