PVR =200 mL is consistently elevated (evaluate for BOO or detrusor underactivity). PVR >300-400 mL indicates significant retention.

What causes elevated PVR?

BOO (BPH, urethral stricture, detrusor-sphincter dyssynergia) and detrusor underactivity (post-spinal cord injury, autonomic neuropathy, post-radiation, advanced age).

Ultrasound: bladder volume = 0.52 x H x W x D (cm). Portable bladder scanner provides immediate bedside results. Catheterization is gold standard but invasive. Measurement should be within 5-15 minutes of voiding.

Post-Void Residual Functional Significance

Interpret post-void residual (PVR) urine volume significance. PVR >300 mL correlates with increased UTI risk and detrusor dysfunction; PVR >400 mL warrants intervention evaluation.
