N13.9: Obstructive and reflux uropathy, unspecified
Urine is flowing back from your bladder into the ureter.
The urinary passages consist of the kidneys, the ureter, the bladder and the urethra.
The ureter is a thin, muscular tube in the abdomen. There is usually one ureter on each side. The urine flows from the kidney, via the ureter, to the bladder. When you have to pass water, the urine flows from the bladder via the urethra and out.
Your urinary passages are constricted. The constriction may occur in the urethra, for example. Pressure in the bladder can increase if the urinary passages are constricted. Urine can flow from the bladder into the ureter if the pressure in the bladder is too high.
Urine is flowing back from your bladder into the ureter. Urine may be flowing back into your kidney. The kidney can be damaged by urine flowing back into it. Urine mostly flows back due to an increase in pressure in the bladder. This happens, for example, when you urinate.
