This paper reports a case and reviews the literature on ureteral involvement in endometriosis, focusing on diagnostic challenges and management. A patient presented with right lower quadrant pain that initially mimicked acute appendicitis, but further evaluation identified right pyonephrosis caused by midureteral endometriosis, alongside a right ovarian mucinous cystadenoma. The authors conclude that diagnosing ureteral endometriosis requires a high index of clinical suspicion and highlight ultrasound as important in assessing acute abdomen in women, with the main caveat being the case-report nature and reliance on literature review. This paper is centrally about endometriosis — it specifically describes ureteral endometriosis presenting as acute pyonephrosis.

Abstract

Background Endometriosis is a common disease, but ureteral involvement is rare. Nonspecific clinical presentations of ureteral endometriosis may result in diagnostic difficulty. Aim To discuss the diagnosis and management of such a case.

Methods

To report a case of ureteral involvement with endometriosis and review the literature.

Results

The case presented with right lower quadrant pain giving rise to initial diagnostic possibility of acute appendicitis. Subsequent evaluation revealed the diagnosis of right pyonephrosis due to midureteral endometriosis with right ovarian mucinous cystadenoma.

Conclusion

The diagnosis of ureteral endornetriosis requires a high index of clinical suspicion. The importance of ultrasound in the evaluation of acute abdomen in women can not be overemphasised. Similar content being viewed by others
