The most common type of bladder weakness experienced by men is a continuous dripping. This is often caused by a swollen prostate, impeding the passage of urine during urination. This results in the bladder not being completely emptied. A swollen prostate can also lead to Urge Urinary Incontinence (UUI), or ‘the sudden need to go’. Prostate surgery can cause the muscles to become temporarily weakened, leading to Stress Urinary Incontinence – involuntary leaks when you laugh, cough or undertake certain physical activities. In some cases, nerves and muscles are damaged during surgery which can cause a more permanent problem.
