PMD, After dribble, Post-void dribble
Definition
Post-Micturition Dribble (PMD), also known as after dribble, is the involuntary loss of urine that occurs immediately after an individual has finished passing urine, typically after leaving the toilet. This condition is distinct from stress incontinence, which is caused by exertion, and from terminal dribble, which occurs at the very end of urination. While PMD can affect women, it is significantly more common in men.1 It is often a bothersome and embarrassing condition, even though most individuals with PMD urinate normally. The dribbling usually happens when the main flow of urine has ceased and clothing is being rearranged, leading to wet trousers or clothes. Even after waiting and gently shaking, the problem often persists. PMD is primarily attributed to a weakness in the pelvic floor muscles that surround the urethra. These muscles can be weakened by factors such as operations for an enlarged prostate, chronic straining during bowel movements (especially with constipation), persistent coughing (e.g., smoker’s cough), being overweight, neurological damage, and consistent heavy lifting. Although other signs of urinary dysfunction are not typically present, some men may experience associated symptoms like urgency, frequency, hesitancy, and straining. Older men who have undergone a prostatectomy may also develop PMD with related urinary symptoms.
Clinical Context
Post-micturition dribble (PMD) is a common and often bothersome form of urinary incontinence, particularly prevalent in men, though it can also affect women.1 It is characterized by the involuntary leakage of urine immediately after urination, even after attempts to shake or wait for residual urine to pass. Clinically, PMD is distinct from terminal dribble (leakage during the final stages of urination) and stress incontinence (leakage due to physical exertion). The primary underlying cause of PMD is often a weakness or increased tone of the pelvic floor muscles surrounding the urethra. Risk factors contributing to PMD include obesity, neurological damage, persistent heavy lifting, surgical complications (such as prostatectomy), and age. Diagnosis typically involves a physical examination, including external perineal assessment or internal rectal examination to evaluate pelvic floor muscle efficiency, and sometimes an ultrasound to ensure complete bladder emptying and rule out residual volume issues. Treatment for PMD primarily focuses on improving pelvic floor muscle function. This can involve pelvic floor muscle release and training, biofeedback using transperineal ultrasound to correct muscle contraction, and bulbourethral massage to help efficiently empty urine from the urethra. Patients are often advised to incorporate home remedies, such as specific exercises during and after urination, waiting a little longer before leaving the toilet, and applying gentle pressure to encourage urine expulsion. While continence pads or shields can be used for managing leakage, the long-term goal of treatment is to eliminate or significantly reduce PMD through targeted pelvic floor therapy. PMD can overlap with other lower urinary tract symptoms (LUTS) such as urgency, frequency, and hesitancy, and has been associated with erectile dysfunction in some studies. Addressing PMD can significantly improve a patient’s quality of life.
