[Intrascrotal herniation of the ureter].

We describe one case of intra-scrotal hernia of the right ureter. The anomaly was recognized on a pre-operatory urogram. It was an extra-peritoneal ureteral hernia. There are two types of ureteral hernia: the para-peritoneal hernia with a peritoneal sac; the extra-peritoneal type with only a fatty hernia. The mecanism of the latter illustrated by our case is a prolapse of the retro-peritoneal fat. It is not possible to practice an urogram before the cure of every inguinal hernia, so the prevention in this rare situation of the damage of ureter is to be cautious in the resection of huge lipomas and sliding fat when operating on inguinal hernias.
