Acute Renal Failure due to Obstructive Uropathy Secondary to Ureteral Endometriosis

Figure 1

Pelvic CT (computed tomography) showed 4.5 cm sized left adnexal mass (black arrow in (a)) abutting with and obstructing the left distal ureter, resulting in severe left hydroureteronephrosis with complete loss of the left renal parenchyma; it also showed right mild hydroureteronephrosis without definite obstructive lesion (white arrows in (a) and (b)).
