[Scrotal diverticulum of the urinary bladder -- rare cause of an inguinal hernia].

INTRODUCTION: Massive herniation of the bladder through the inguinal canal is a rare entity. We report on a patient with a large inguinoscrotal herniation of the urinary bladder commonly referred as "scrotal cystocele". Diagnostic means and therapeutic strategies are discussed. CASE REPORT: After laparoscopic repair of a bilateral inguinal hernia, a 60-year-old man described a persistent right groin mass that varied in size with the degree of bladder distension. Diagnostic evaluation revealed a large bladder diverticulum extending into the right scrotum. Treatment consisted of inguinal resection of the bladder diverticulum, the peritoneal sack and closure of the hernia.
CONCLUSION: Inguinal herniation of a large bladder diverticulum has to be considered in the differential diagnosis of inguinal hernias, especially in patients with obstructive symptoms of the bladder outlet.
