Silent loss of kidney seconary to ureteral endometriosis

Ureteral endometriosis is a serious localization of disease burden that can lead to urinary tract obstruction, with subsequent hydroureter, hydronephrosis, and potential kidney loss. Diagnosis is elusive and relies heavily on clinical suspicion as ureteral endometriosis can occur with both minimal and extensive disease. Surgical technique to treatment varies, but the goal is to salvage renal function and decrease disease burden.

We describe 3 cases in which there was documentation of renal atrophy and function loss with subsequent workup and surgical intervention.

The cases illustrate varying surgical approaches tailored to localization of ureteral endometriosis. All cases were carried out laparoscopically.

Ureteral endometriosis, albeit rare, can be complicated by potential loss of renal function. Clinical suspicion and preoperative assessment may help with diagnosis and allows for a multidisciplinary preconsultation. Laparoscopic surgical approach is based on extent of disease and localization and can be carried out successfully in the hands of a highly experienced laparoscopic surgeon.
