[Mixed type ureteral endometriosis : a case report and a review of the Japanese literature].
Ureteral endometriosis is a rare but important clinical problem that requires early detection and treatment. The urinary tract is affected in approximately 2% of women with endometriosis. Even though the bladder is the most frequent urinary tract organ affected in these patients,the ureter is also affected in 10-40% of the cases, thus requiring immediate clinical attention. The majority of endometrial lesions is typically located in the lower segment of the ureter and is often difficult to differentiate between endometriosis and malignancy. Ureteral endmetriosis should be considered for women with hydronephrosis. In this report we present one clinical case of mixed-type ureteral endometriosis. A 37-year-old woman was referred to our hospital due to left hydronephrosis. Contrast-enhanced CT scan confirmed left hydronephrosis and also showed a solid mass at the left lower ureter. Retrograde pyelography revealed stenosis of the left lower ureter and Renogram revealed severely impaired renal function. Laparoscopic nephroureterectomy was performed. Pathologically, mixed-type endometriosis of the left ureter was diagnosed.
