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 is moved via peristaltic waves of smooth muscle contraction that start at renal pelvis. When the wave reaches the urinary bladder, urine spurts into the bladder. The ureter opening into the bladder has a flap of tissue over it that acts as a valve to prevent backflow of urine.
