Clinical Analysis of the Diagnosis and Treatment of Ureteral Endometriosis

Objective: To review our experience in the diagnosis and treatment for 23 cases with ureteral endometriosis.Methods: A retrospective analysis was performed on 23 cases of ureteral endometriosis with histopathological from 2002 to 2011.Results: 23 cases of ureteral endometriosis were diagnosed by ultrasound,in which 21 cases were examined by intravenous pyelography,11 cases were examined by retrograde urography,16 cases were examined by CT scan and 8 cases were examined by MRI.All the cases were treated by surgery,including ureterolysis in 3 cases,partial ureteral resection and ureterocystoneostomy in 6 cases,partial ureteral resection and end-to-end ureteral anastomosis in 12 cases,and endoscopic resection of ureteral endometriosis lesion in 2 cases.All the pathologic results of the 23 cases were endometriosis.Conclusion: Ureteral endometriosis was a rare disease in urology clinical scenarios.The early diagnosis of the disease was very difficult.Image analysis played an important role in the diagnosis of ureteral endometriosis.For cases with mild ureteral obstruction,the recommended management was ureterolysis while for those with moderate and severe ureteral obstruction,the recommended procedure was partial ureteral resection.For pathological severe cases,it was remmendable to apply hormone therapy to reduce postoperative recurrence rate.
