7. Slow urinary stream
This is also a classic sign of prostate enlargement and can be caused by benign prostatic hyperplasia or prostate cancer. A slow urinary stream is also described as a weak urinary stream, and it is caused by a reduction of the urethral lumen. As mentioned above, the prostate is located below the urinary bladder and around the urethra. As it increases in volume, the gland causes an obstruction and reduces the urethral opening. There is a reduced volume of urine circulating through the urethra, which makes the urinary stream slower or weak. This is one of the earliest symptoms, nocturia and the increase in urinary frequency.
