Post void residual (PVR) measurement is a test to see how much urine stays in your bladder after you have finished urinating. Normally, the bladder empties almost completely. A high PVR means you are not emptying your bladder fully, which can lead to problems like infections or kidney damage. This test helps doctors find the cause and decide on the best treatment.
Key facts
It is a common test performed when someone has symptoms of incomplete bladder emptying, such as frequent urination, weak urine stream, or feeling like the bladder is never empty.
People of all ages can have a high PVR. It is more common in older adults, people with prostate problems (in men), women after childbirth or with pelvic organ prolapse, and people with nerve conditions like diabetes or spinal cord injury.
Post void residual is measured after you urinate. Your doctor will ask you to empty your bladder as much as you can into a special container. Then, within a few minutes, the amount of urine left in your bladder is measured using a portable ultrasound device or by inserting a thin, flexible tube (catheter) through the urethra into the bladder.
The test is quick and usually painless. For ultrasound, you will lie down while a small device is pressed against your lower belly. For catheterization, you may feel a brief sting or pressure. Your doctor will explain the results and what they mean for your health.
Treatment depends on the cause and how much residual urine you have. The goal is to help your bladder empty better and prevent complications like infections or kidney damage. Options include simple self-care strategies, medicines to relax muscles or shrink the prostate, and sometimes surgery.
Depending on the cause, your doctor may suggest medicines to relax the bladder neck and prostate (for men) or to strengthen bladder contractions. Never start or stop any medicine without talking to your healthcare provider. In some cases, a temporary or permanent catheter may be needed to drain urine regularly.
Living with a high PVR means paying attention to your bathroom habits. Set a regular voiding schedule, practice double voiding, and keep a diary of your symptoms to share with your doctor. If you use a catheter, learn proper cleaning techniques to reduce infection risk.
A balanced diet supports overall bladder health. Pelvic floor exercises (Kegels) can help strengthen muscles that control urination, but it is important to do them correctly – ask a physiotherapist or healthcare provider for guidance.
Not all causes of high PVR can be prevented, but you can reduce your risk by staying active, eating a healthy diet, managing medical conditions like diabetes, and avoiding prolonged use of medicines that affect urination without medical guidance.
There is no routine screening for high PVR for the general population. However, if you have risk factors (like an enlarged prostate or nerve disease), your doctor may monitor your bladder function as part of your regular care.
With proper diagnosis and treatment, most people can manage a high PVR successfully and avoid serious complications. Treatment often improves symptoms and quality of life. Even when the underlying condition cannot be cured, steps like intermittent catheterization can keep the bladder healthy and prevent infections.

Surgery may be considered if there is a blockage that does not respond to other treatments, such as an enlarged prostate, urethral stricture, or pelvic organ prolapse. The type of surgery depends on the specific problem and your overall health.
Ongoing urinary problems can cause embarrassment, anxiety, and even depression. It may affect your social life, sleep, and self-confidence. Remember, you are not alone – many people manage these issues effectively with treatment and support.
