Table 1. Comparison between median PVR-R and PVR of obstructed and unobstructed patients according to detrusor contractility; comparison between median PVR-R and PVR of underactive and non-underactive patients based on the obstruction.
| PVR-R/PVR | DUA+ | DUA− | p-value | |
|---|---|---|---|---|
| BOO+ | PVR-R (%) | 50 | 24 | <0.001 |
| PVR (mL) | 225 | 70 | <0.001 | |
| BOO− | PVR-R (%) | 17 | 0 | <0.001 |
| PVR (mL) | 70 | 0 | <0.001 | |
PVR-R, post-void residual urine ratio; DUA, detrusor underactivity; BOO, bladder outlet obstruction.
