###Human: My 7 year old daughter has repeated urine infections. How to clear it out? ###Assistant: Hello. Once this episode resolves, she needs an ultrasound KUB (kidney, ureters, and bladder) with PVR (post-void residual urine test) and micturating cystourethrogram (MCU). A renal nuclear scan may be required depending upon the result of these investigations. For more information consult a urologist online -->
