Non-Invasive
- Eliminates catheters used in conventional urodynamics (UDS) and the associated complications, fear, and pain [1,2,3]
- Suitable for patients unable to or who refuse to undergo conventional UDS
- Improves patient compliance
Accurate
- 86% sensitivity and 89% specificity for detecting BOO compared to conventional invasive UDS [4,5] (uroNIRS was used in conjunction with uroflowmeter-measured Qmax and ultrasound-measured PVR)
- Avoids the error associated with catheterization in measuring flow rates (Qmax) [6]
Efficient
- Fast and easy catheter-free procedure
- Compact and portable system for fast setup
- Cost effective – one operator and one disposable sensor patch
