RESUMEN
The incarceration of the bladder in the ininguinal hernia is rare. Often asymptomatic, the diagnosis is made during surgery or postoperatively due to complications. We report the case of a patient with a right inguino-scrotal hernia associated with urinary symptoms and whose retrograde urethrocystography [UCR] showed an bladder totally intra scrotal. Incarceration of the bladder in the hernial sac is found only in 1-4% of inguinal hernias, the total extra abdominal bladder migration is even more exceptional. The association of inguinal hernia and urinary irritative and obstructive signs should suggest the diagnosis, however it is most often done during surgery. Confirming diagnosis is provided by the opacification of the lower urinary tract [cystourethrography or retrograde intravenous urography] or by CT. The treatment includes the cure of the hernia with bladder reintegration. Resection of the herniated bladder portion is needed only in case of large hernia or narrow neck. The preoperative diagnosis avoids postoperative complications
