PVR (post-void residual) on abdominal ultrasound is the volume of urine remaining in the bladder after voiding. It helps detect urinary retention, incomplete emptying from BPH, neurogenic bladder, or obstruction. Measured with bladder ultrasound; <50 mL is generally normal, up to ~100 mL may be acceptable in older adults, while >200 mL often indicates clinically significant retention needing further evaluation.

USG whole abdomen with PVR is an ultrasound scan imaging all major abdominal organs (liver, gallbladder, pancreas, spleen, kidneys, urinary bladder and abdominal aorta) combined with measurement of post‑void residual (PVR) urine. It evaluates organ size, stones, masses, fluid, and urinary retention by scanning before and after voiding. The test is non‑invasive, uses sound waves, and may require fasting and an initially full bladder.

The post-void residual (PVR) test measures how much urine remains in the bladder after urination. It’s used to evaluate bladder emptying and diagnose urinary retention, obstructive issues (e.g., BPH), or neurogenic bladder. Results guide management—watchful waiting, catheterization, medications, or surgery—and help assess recurrent urinary infections or persistent urinary symptoms. PVR is measured by ultrasound bladder scan or catheterization.

Post-void residual (PVR) is normally low—generally under 50 mL. Values under 100 mL are often acceptable, especially in older adults. A PVR consistently over 100 mL warrants evaluation, and volumes above 200 mL usually indicate clinically significant urinary retention needing assessment and management. Interpret PVR alongside symptoms and clinical context; repeat measurements or bladder scanning may be recommended.

Cost varies by country and setting. On public systems it’s often covered; private clinics in the US typically charge about $100–400. In India, diagnostic centres usually charge roughly ₹300–1,500. Hospital, emergency or specialist fees can raise costs. Always check with the specific clinic or your insurer for exact pricing and whether the test is included under your plan.

Proliferative vitreoretinopathy (PVR) can be serious: it causes scar tissue formation on the retina after detachment, often leading to recurrent detachments and reduced visual outcome. It’s a leading cause of retinal surgery failure and may require complex, repeated operations. Prognosis varies with severity, duration, and macular involvement; earlier detection and specialist surgical care improve chances of preserving vision.
