[Aneurysm of the abdominal aorta, retroperitoneal fibrosis and extramembranous glomerulitis].

The authors report a case of a 58 year old male presenting with bilateral ureteral compression by peri-aneurysmal retroperitoneal fibrosis. A ureterolysis and prosthetic replacement of the abdominal aorta gave good results. Eighteen months postoperatively, proteinuria and an edema of the lower limbs revealed an extramembranous glomerulitis, for which no cause could be found. Was this rare association fortuitous, or does it result from the action of some unknown antigen?
