About bladder outflow obstruction

Urine (pee) is made in your kidneys and collects in your bladder until it flows out through your urethra. Your prostate sits where your bladder meets your urethra.

It is normal for your prostate to grow as you get older. Due to the position of your prostate at the opening of your bladder, an enlarged prostate can restrict the outflow or passing of urine

Common symptoms of bladder outlet obstruction

  • Difficulty starting urination It is common for patients to have to stand or sit for a few minutes before being able to start to pee. Remember that this is normal with your condition and try to be patient with yourself.
  • Slow stream of urine Patients often notice that the stream of their urine is slow, and may even stop, despite their bladder being full. This means that it can take longer than normal to pass urine.
  • Frequency and urgency of urination You may notice that you need to empty your bladder more, and that you can’t resist the feeling of needing to urinate (urgency). This at times we know can be embarrassing and can sometimes lead to urine leakage if it is not possible to hold on.
  • Post-micturition dribble After the flow of urine a few drops of urine may still be in the urethra and dribble out into your underwear after you leave the bathroom.
  • Nocturia Waking in the night to pass urine occurs due to the change in position of the bladder, and how it fills when you are lying down compared to when you are standing up. Nocturia can be very distressing as it affects the quality of sleep.
  • Erectile dysfunction It is common for patients who have enlarged prostates to suffer with sexual dysfunction such as soft or absent erections. There are treatments which may be suitable for you to help with this.
