in benign prostatic hyperplasia (bph) the prostate gland grows in size. it may compress the urethra which courses through the center of the prostate. this can impede the flow of urine from the bladder through the urethra to the outside. it can cause urine to back up in the bladder (retention) leading to the need to urinate frequently during the day and night. other common symptoms include a slow flow of urine the need to urinate urgently and difficulty starting the urinary stream. more serious problems include urinary tract infections and complete blockage of the urethra which may be a medical emergency and can lead injury to the kidneys.
