Intrinsic ureteric involvement by endometriosis: a case report.

Endometriosis occasionally involves the urinary tract, and a ureteral obstruction from this order constitutes a rare variant with serious consequences. Intrinsic ureteric involvement by endometriosis is an exceedingly rare event. This case report describes intrinsic ureteric involvement by endometriosis. The case involved 47-year-old woman, gravida 4, para 2, who had a 4-year history of dysmenorrhea and hypermenorrhea. An intravenous pyelogram showed a right hydronephrosis. She underwent a total abdominal hysterectomy and a right ureteroureterostomy. A pathologic examination revealed complete obstruction of the right ureter by intrinsic intramural endometriosis. We conclude that because ureteral endometriosis, especially intrinsic endometriosis, is usually silent and results in a high rate of renal loss before recognition, physicians should have a hightened awareness of this uncommon but serious manifestation of endometriosis.
