Ureteroinguinalheniation is a typically rare event. It is most often diagnosed with signs of complications, such as Ureterohydronephrosis on strangulation or kinking of the ureter, mostly objectified on balance sheets of unilateral lumbago. The ureter inguinal hernia must be a systematic differential diagnosis in the presence of a clinical examination revealing a clinical inguinal hernia associated with urinary signs such as unexplained ureterohydronephrosis or urinary infection or even renal failure. Here we report the case of a patient with left ureter inguinal hernia objectified in front of left lumbar pains, whose scanner showed the ureter which was bent in the hernia sac. A surgical cure of the hernia was carried out with a good evolution and disappearance of Ureterohydronephrosis.
