Background: Endometriosis mainly occurs in the pelvic tissues and organs of women. Endometriosis in the kidney is extremely rare, and to the best of our knowledge, this article reports the first case of endometriosis in the ectopic kidney.
Case presentation: We describe a case of a 19-year-old girl with occasional mild abdominal pain, who was admitted to hospital due to the discovery of an ectopic left kidney. SPECT-CT showed no abnormal radioactive distribution was found in the left pelvis, suggesting that the left ectopic kidney was not functioning. Laparoscopic left ectopic kidney resection was subsequently performed. Histopathology revealed endometriosis of the ectopic left kidney.
Conclusions: In female patients with clinical manifestations of abdominal pain and gross hematuria, the possibility of renal endometriosis should be considered.
Background
Endometriosis mainly occurs in female pelvic organs. Endometriosis in the kidney is extremely rare.
Case presentation
We herein describe a case of a 19-year-old girl with occasional mild abdominal pain associated with an ectopic left kidney. SPECT-CT showed no abnormal radioactive distribution in the left pelvis, suggesting loss of function of the ectopic kidney. Laparoscopic left ectopic kidney resection was subsequently performed. Histopathology revealed endometriosis of the ectopic left kidney.
Conclusions
In female patients with clinical manifestations of abdominal pain and gross hematuria, the possibility of renal endometriosis should be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
