Difficulty passing urine can affect males and females, though it is particularly common in men as they get older, often relating to changes in the prostate.

Symptoms might include:

In men, the causes of a blockage include prostate enlargement, prostate cancertight foreskin or urethral stricture.

In both men and women difficulty passing urine could be related to the narrowing of the urethra and stones.

Poor urinary flow may not require treatment, but tests should be made to ensure there are no underlying conditions to be concerned about.
