Overview
Dr. Reena Malik discusses postvoid dribble (after dribble), its causes, recent research on treatment options, and practical steps for management and when to seek specialist care.
Definition and Prevalence
- Postvoid dribble is involuntary urine leakage after urination, affecting both men and women.
- Occurs in 8% to 63% of men; most common complaint among men with post-urination issues.
Causes of Postvoid Dribble
- Most commonly caused by enlarged prostate, leading to urine trapping behind the prostate.
- Urethral narrowing elsewhere can also trap urine, causing delayed leakage.
- Weakness or neuromuscular changes in muscles around the urethra may contribute, especially with aging.
Research and Treatment Options
- Recent systematic review (up to June 2023) identified four randomized controlled trials on postvoid dribble treatments.
- Two studies evaluated pelvic floor muscle exercises, two studied daily PDE5 inhibitors (for erectile dysfunction).
- Pelvic floor exercises aim to strengthen muscles to improve urine expulsion.
- Urethral milking involves manual pressure on the perineum to expel trapped urine.
Study Outcomes
- Australian study: Pelvic floor exercises reduced pad weight by 4.7g, urethral milking by 2.9g; control group showed no change.
- UK study: 75% showed improvement with pelvic floor exercises vs. no change with lifestyle advice.
- PDE5 inhibitor studies showed significant decreases in dribble, but measurement methods had limitations; clinical significance uncertain.
Practical Management Strategies
- Urethral milking after urination may help expel residual urine.
- Consult a urologist for assessment of enlarged prostate or urethral narrowing, as both are treatable.
- Try pelvic floor muscle exercises (e.g., Kegels) to strengthen relevant muscles.
- Consider working with a pelvic floor physical therapist or using online resources for guidance.
Important Precautions
- Stop exercises and consult a urologist if experiencing new pain, changes in urination or bowel movements, or pain during erection or ejaculation.
Recommendations / Advice
- Attempt urethral milking and pelvic floor exercises for management.
- Seek professional evaluation if symptoms persist or other urinary issues develop.
- Avoid excessive tensing of pelvic floor muscles to prevent dysfunction.
