[Ureteral obstruction secondary to endometriosis. Report of a case]

The urinary tract is rarely affected by endometriosis, urinary bladder being the most common location. This paper presents one case of advanced extrinsic endometriosis which initially presented as obstructive pyelonephritis. The diagnostic methodology, including uro-tomographic imaging, is evaluated. Although good results have been reported with hormone-therapy, we support the surgical approach sanctioned by the patho-anatomical findings.
