Some common alterations of renal and urinary tract function in children include: Hydronephrosis: A blockage that causes urine to back up into the kidney, making it appear enlarged on an ultrasound Reflux: A valve-like mechanism at the point where the ureter joins the bladder doesn't work, allowing urine to wash back up into the kidney Ureteropelvic junction obstruction: A blockage in the area where the renal pelvis meets the ureters Ureterovesical junction obstruction: A blockage in the area where the ureter meets the bladder Multicystic dysplastic kidney: When fluid-filled sacs or cysts...

Some common alterations of renal and urinary tract function in children include:
Hydronephrosis: A blockage that causes urine to back up into the kidney, making it appear enlarged on an ultrasound
Reflux: A valve-like mechanism at the point where the ureter joins the bladder doesn't work, allowing urine to wash back up into the kidney
Ureteropelvic junction obstruction: A blockage in the area where the renal pelvis meets the ureters
Ureterovesical junction obstruction: A blockage in the area where the ureter meets the bladder
Multicystic dysplastic kidney: When fluid-filled sacs or cysts replace normal kidney tissue
Polycystic kidney disease: Usually inherited, in which the kidneys are replaced by fluid-filled cysts, often leading to renal failure 

Other common conditions of the urinary tract in children include: Urinary tract obstruction such as a calculus, or an obstructive posterior urethral valve
