Minimally invasive treatment of an ectopic kidney stone: a case report and literature review

Chenglu Wang et al. J Int Med Res. 2019 Sep.

Abstract

An ectopic pelvic kidney is a rare congenital anomaly with a high incidence of complications such as reflux, hydronephrosis, nephrolithiasis, and even renal failure. We herein report a case of transperitoneal laparoscopic pyelolithotomy for treatment of a left pelvic kidney stone and discuss various surgical procedures based on the published literature. A 64-year-old woman presented to our hospital with generalized weakness and occasional nonspecific waist pain in October 2017. Computed tomography showed a 2.6-cm renal pelvis stone located in the left ectopic pelvic kidney with severe hydronephrosis. The patient underwent transperitoneal laparoscopic pyelolithotomy and was discharged 7 days after surgery. Various treatment procedures are available for ectopic kidney stones. Proper preoperative assessment and selection of the most suitable surgical procedure play critical roles in successful treatment.

Keywords: Pelvic kidney; anatomic variation; kidney stone; pyelolithotomy; renal ectopy; surgery.
