Patient with pelvic pains: retroperitoneal fibrosis or pelvic endometriosis? A case report and review of literature

The cause of hydronephrosis could be a physiologic hydroureteronephrosis, which is the most common cause of dilatation of the urinary tract in pregnancy. The pain symptoms of the patients seemed to be linked to endometriosis and not to retroperitoneal fibrosis. Magnetic resonance imaging sometimes does not enable a correct diagnosis between these two pathologies. Fertile women with suspected fibrosis should undergo a diagnostic laparoscopy by an expert surgeon in retroperitoneal surgery.
