    What are the complications of Ectopic Kidney ?
    ### Response:
    Possible complications of an ectopic kidney include problems with urine drainage from that kidney. Sometimes, urine can even flow backwards from the bladder to the kidney, a problem called vesicoureteral reflux (VUR). More information about VUR is provided in the NIDDK health topic, Vesicoureteral Reflux.
