postvoidresidu

Postvoid residual (PVR) is a clinical measurement used to assess the amount of urine remaining in the bladder after a person has voided or urinated. It provides important information about bladder emptying efficiency and can help diagnose underlying urinary tract disorders.

The measurement of postvoid residual is typically performed using ultrasound, catheterization, or other imaging techniques shortly after urination. A small amount of residual urine, usually less than 50 milliliters, is considered normal in healthy individuals. Higher residual volumes may indicate incomplete bladder emptying due to various conditions such as bladder outlet obstruction, detrusor muscle weakness, or neurological impairments affecting bladder function.

Elevated PVR levels can lead to urinary tract infections, bladder distention, or other complications if persistent. Therefore, assessing postvoid residual is a routine part of evaluating patients with lower urinary tract symptoms, including difficulty urinating, weak urinary stream, or recurrent urinary infections.

The measurement is often incorporated into urological assessments and can guide treatment decisions. For example, increased residuals may prompt further investigation or interventions such as medication, urinary catheterization, or surgical procedures to ensure complete bladder emptying.

In summary, postvoid residual is a valuable clinical parameter for diagnosing and managing urinary dysfunctions, helping to monitor the effectiveness of treatments and guiding appropriate patient care.
