Introduction
Bladder, despite approaching to inguinal region, rarely drops into inguinal canal causing bladder herniation. Bladder herniation only accounted for 1-3% of all inguinal herniation1, while the incidence may reach up to 10% among obese patient over 50 years old2. Most of the cases are generally asymptomatic, while the advanced cases must complete two-stage urination by compressing scrotal-bladder manually3. As most of the hernia are diagnosed by physical examination without advance radiology exam prior to operation, only 7% of inguinal bladder hernia is diagnosed before the herniorraphy. Therefore, 16% of these condition are found by intraoperative or postoperative complication such as bladder injury and bladder leakage4. In this manuscript, we reported a bladder herniation diagnosed prior to operation and repaired by laparoscopic extraperitoneal approach (TEP) herniarraphy.
