This 2016 case report examines a woman with cyclic pelvic and left flank pain, using imaging studies followed by laparoscopic evaluation to investigate suspected deep infiltrating endometriosis. The authors report bilateral endometrioma and deep infiltrating disease causing extrinsic ureteral infiltration and hydronephrosis, framed as ureteral endometriosis leading to “silent” obstructive uropathy and potential renal failure. The main limitation is that the evidence is limited to a single patient case and does not establish incidence, diagnostic accuracy, or generalizability. This paper is centrally about endometriosis — specifically ureteral endometriosis causing silent ureteral obstruction and hydronephrosis.

Abstract

Endometriosis is defined as the presence of active endometrial \ntissue outside the uterine cavity affecting 15% of women at \nreproductive age. Ureteral endometriosis (UE) is a rare type of \nendometrial involvement affecting 0.1% - 1% of women with \nendometriosis. UE is quite uncommon and underdiagnosed \nbecause of the patients’ nonspecific symptoms of endometriosis. \nHowever, it is important to diagnose and manage UE treatment \nsince it can lead to renal failure due to silent obstruction of \nthe ureter. This case report describes a woman who presented \nwith cyclic pelvic pain and left flank pain. Imaging studies and \nlaparoscopic findings revealed bilateral endometrioma and deep \ninfiltrating endometriosis (DIE) findings resulting in extrinsic \ninfiltration of the ureter and hydronephrosis.

Abstract

Endometriosis is defined as the presence of active endometrial tissue outside the uterine cavity affecting 15% of women at reproductive age. Ureteral endometriosis (UE) is a rare type of endometrial involvement affecting 0.1% - 1% of women with endometriosis. UE is quite uncommon and underdiagnosed because of the patients’ nonspecific symptoms of endometriosis. However, it is important to diagnose and manage UE treatment since it can lead to renal failure due to silent obstruction of the ureter. This case report describes a woman who presented with cyclic pelvic pain and left flank pain. Imaging studies and laparoscopic findings revealed bilateral endometrioma and deepinfiltrating endometriosis (DIE) findings resulting in extrinsic infiltration of the ureter and hydronephrosis.Keywords: Endometriosis, Ureter, Hydronephrosis, Magnetic resonance imaging, Laparoscopy
