Post-Void Residual Urine: Causes, Symptoms, and Treatment Options

Why Does the Bladder Not Empty Completely?

1. Bladder Outlet Obstruction (BOO): Blockage in the urine flow pathway. In males, common causes include enlarged prostate (BPH) and urethral strictures. In females, urethral prolapse, pelvic organ prolapse, or tumors.

2. Weak or Impaired Bladder Contraction: Neurological conditions (diabetes, spinal cord injury, multiple sclerosis) can affect nerves controlling bladder function, leading to weak contractions.

3. Neurogenic Bladder Dysfunction: General term for bladder problems from nerve damage or dysfunction, resulting in incomplete emptying.

4. Pelvic Floor Dysfunction: Weak or tight pelvic floor muscles can impair bladder emptying.

5. Medications: Antihistamines, antidepressants, decongestants, and opioids can cause urinary retention.

6. Constipation: Chronic constipation puts pressure on the bladder, hindering complete emptying.

7. Urinary Incontinence: Paradoxical incontinence (overactive bladder with incomplete emptying) can contribute.

8. Structural Abnormalities: Rare anomalies like bladder or urethral diverticula.

Consult a healthcare professional for persistent incomplete emptying. They will assess the cause and guide appropriate treatment.
