A 77-year-old male visited our hospital complaining of swelling in the right scrotal and inguinal region, urinary urgency and difficulty of urination. Physical examination revealed an elastic soft mass in the right inguinal region toward the right scrotum. Rectal examination proved that the prostate was moderately enlarged. Cystogram and urethrography showed hernia of the bladder into the right scrotum and benign prostatic hyperplasia. Urodynamic studies demonstrated organic obstruction in the lower urinary tract. Transurethral resection of the prostate was done for benign prostatic hyperplasia. Later, surgical treatment for the bladder hernia was performed by replacing the bladder into the pelvic cavity and closing the hernial ring without resection of the bladder wall. The bladder hernia proved to be a para-peritoneal type. The postoperative course was uneventful. The previous reports of urinary bladder hernia are reviewed and the incidence, etiology, diagnosis the treatment are discussed.
