Sliding inguinal scrotal herniation of the bladder is rare but well-documented in the medical literature. The majority of the patients are asymptomatic and the hernia is usually diagnosed incidentally. Most authors had advocated surgically repair of the hernia with the reduction or resection of the bladder as the definitive management. We present an unusual case of inguinal scrotal herniation of the bladder presented as acute abdominal pain and treated with conservatively with urethral catheterization.
