2Urgency to urinate
Urgency to urinate is a commonly reported symptom in both benign prostatic hyperplasia and prostate cancer. In both cases, there’s an abnormal increase of volume in the prostate gland, and such increase usually increases the pressure in the pelvic cavity. In this region, we can find the rectum and the urinary bladder. The rectum will be located behind the prostate, and the urinary bladder is located above and in front of the gland.
The urgency to urinate from prostate cancer usually arises as a result of the compression of the urinary bladder. However, prostate cancer usually starts to grow towards the rectum and not the bladder, so it is not necessarily an early symptom. It is more common in benign prostatic hyperplasia, but certain types and locations of prostate cancer might cause urgency to urinate.
Patients would also report an increased frequency of urination, especially at night. They usually reduce the amount of liquid intake before bedtime in order to prevent spending the night at the bathroom. Each time they pass water, they won’t produce a lot of urine, they fail to empty the bladder, and that’s why the urge to urinate again comes back after a few hours or minutes.
