Feasibility of robot‑assisted radical cystectomy in a patient with an ectopic kidney: A case report

Abstract

An ectopic kidney is a rare congenital defect in which the kidney does not migrate to its normal anatomical position. In the present study, a robot-assisted radical cystectomy and intracorporeal urinary diversion were performed for a patient with an ectopic kidney. The present study describes the case of a 72-year-old male patient who was diagnosed with a bladder tumor by magnetic resonance imaging and cystoscopy. A transurethral resection of the bladder tumor was performed. The pathological examination revealed an invasive urothelial carcinoma. Contrast-enhanced computed tomography revealed an ectopic left kidney in the upper pelvis. A robot-assisted radical cystectomy, extended lymph node dissection and intracorporeal urinary diversion were performed. On the whole, as demonstrated herein, a robot-assisted radical cystectomy with intracorporeal urinary diversion is a feasible approach for muscle-invasive bladder cancer complicated by an ectopic kidney.

Applicability and feasibility of robot-assisted cystectomy and intracorporeal urinary diversion in a patient with right renal pelvic ectopia

“…Despite the growing use of robot-assisted radical cystectomy (RARC) ( 3 , 4 ), there is limited data on its application in ectopic kidneys. Only one RARC case has been reported ( 5 ), in contrast to numerous open radical cystectomies ( 1 , 6 ) involving an ectopic kidney.…”
