The PVR medical abbreviation has three main meanings, and the specialty decides which one applies: post void residual in urology and nursing, pulmonary vascular resistance in heart and lung care, and pulse volume recording in vascular testing. A fourth meaning, proliferative vitreoretinopathy, belongs to eye surgery.
Each one measures something very different, from urine left in the bladder to pressure in the lung arteries to blood flow in the legs. The units that follow the letters are often the fastest clue: milliliters point to the bladder, Wood units point to the lungs, and a pairing with ABI points to the legs. The sections below explain each meaning in turn.

PVR medical abbreviation in urology: post void residual
Post void residual is the amount of urine still in the bladder right after a person has tried to empty it. Void is the clinical word for urinating, and residual means what is left over. A large leftover volume suggests the bladder is not emptying well, which can come from an enlarged prostate (BPH), nerve problems, some medicines, constipation or the effects of surgery and anesthesia.
Staff usually measure it with a handheld bladder scanner, a small ultrasound probe placed on the lower belly. Less often, a thin catheter is passed to drain and measure the urine directly. Small amounts are normal. What counts as too much varies by age and setting, so each hospital or clinic sets its own threshold for action.
A post op nursing note: "Voided 150 mL, PVR by bladder scan 320 mL, straight cath per protocol." The patient passed some urine, but a lot stayed behind, so the nurse drained the bladder once with a catheter as the unit's protocol allows.
PVR in cardiac and lung care: pulmonary vascular resistance
In cardiology and pulmonary medicine, PVR means pulmonary vascular resistance, a measure of how hard the right side of the heart must push to move blood through the lungs. It is calculated during a right heart catheterization from pressures and blood flow, and it is reported in Wood units or in dynes. A raised value is part of how pulmonary hypertension is classified, and transplant teams check it closely before a heart transplant.
You will usually see it in a cath lab report next to pressures such as mean pulmonary artery pressure and wedge pressure, and alongside PAH in the problem list. Its partner on the body side is SVR, systemic vascular resistance.
PVR in vascular testing: pulse volume recording
In a vascular lab, PVR means pulse volume recording. Blood pressure cuffs are placed at several levels on the legs or arms, gently inflated, and a machine records the small change in volume with each heartbeat as a waveform. A sharp, tall wave suggests good flow, while a flat, rounded wave suggests narrowing upstream. The test is often done together with an ABI, the ankle brachial index, which is why reports read "ABI/PVR."
The pair helps diagnose and grade PAD, peripheral artery disease, and track it after a bypass or stent.
A quick way to tell the meanings apart
| Meaning | Setting | Typical clue |
|---|---|---|
| Post void residual | Urology, nursing floors, rehab | Bladder scan, mL, voided, cath |
| Pulmonary vascular resistance | Cath lab, pulmonary hypertension clinic | Wood units, right heart cath, mPAP |
| Pulse volume recording | Vascular lab | ABI/PVR, waveforms, cuff levels |
| Proliferative vitreoretinopathy | Retina surgery | Retinal detachment, vitrectomy |
When none of these clues are present, check with the author of the note. Each meaning leads to very different next steps.
Notes for students and new staff
Nursing students meet post void residual early, often in the same breath as urinary retention and catheter care. Cardiac and respiratory students learn pulmonary vascular resistance with the other hemodynamic numbers. Vascular technologist trainees learn pulse volume recording with the ABI. Spelling the term out the first time in a shared note avoids confusion when a chart passes between these teams. The labs and tests section lists related measurements.
A PVR result means different things in different settings, so the clinician who ordered or performed your test is the one to explain how it fits your situation.
Frequently asked questions
What does PVR mean on a bladder scan?
It means post void residual, the urine left in the bladder after urinating. The scanner estimates the volume in milliliters. Your care team decides what level needs action.
What is the PVR medical abbreviation in urology?
In urology PVR stands for post void residual. It helps show whether the bladder empties completely, which matters in prostate enlargement and nerve related bladder problems.
What does ABI PVR mean on a vascular report?
ABI is the ankle brachial index, and PVR is pulse volume recording. Together they check blood flow to the legs and help detect peripheral artery disease.
What does PVR mean in a heart catheterization report?
It means pulmonary vascular resistance, a calculated measure of resistance to blood flow through the lungs. It is reported in Wood units and is important in pulmonary hypertension and transplant care.
