Answers from Erik P. Castle, M.D. Bladder outlet obstruction in men is a blockage that slows or stops urine flow out of the bladder. Bladder outlet obstruction can cause urine to back up in your system, leading to difficulty urinating and other uncomfortable urinary symptoms. Possible causes of bladder outlet obstruction might include:
Urine flows from each kidney through tubes called ureters and into the bladder. When the bladder is full, it squeezes and sends the urine out through the urethra. No urine should flow back into the ureter when the bladder is squeezing. Each ureter has a one-way valve where it enters the bladder that prevents urine from flowing back up the ureter. But in some people, urine flows back up to the kidney. This is called vesicoureteral reflux. Over time, the kidneys may be damaged or scarred by this reflux. This is called reflux nephropathy. Reflux can occur in people whose ureters do not attach properly to the bladder or whose valves do not work well.
