ABSTRACT
Massive urinary bladder herniation is an uncommon condition. A 65-year-old obese man was ad-mitted to our hospital complaining of dysuria, urinary frequency, urgency, two phased urination, recurrent urinary tract infection and a large scrotal mass. The patient was investigated with intra-venous pyelography (IVP), cystography and computed tomography (CT). A big mass of inguinal hernia consisting of a part of the urinary bladder and propagating to scrotum was detected. The hernia was explored, the herniated part of the bladder was retracted and repositioned, fascial de-fect was repaired. This case emphasizes that patients who complain of two phased urination and a scrotal mass should be evaluated carefully since bladder can be herniated to scrotum. Otherwise, patients going through operation for inguinal hernia may cause suprises for the surgeon.
