Abstract

OBJECTIVE:

A prospective study was conducted to evaluate the use of color Doppler ultrasound in the investigation of female urinary incontinence.

METHODS:

Thirty-seven patients underwent a full urodynamic assessment and translabial ultrasound examination using color Doppler-capable equipment with 5-7-MHz curved array transducers, both in the supine and in the erect positions.

RESULTS:

More than minimal leakage was seen in 13 patients by Doppler and in 16 by fluoroscopic imaging. Results were in agreement in 28/37 cases (kappa 0.49). The observed discrepancies may have been due to initial technical difficulties, differences in bladder filling and the presence of a catheter on fluoroscopic imaging. In five incontinent patients, urethral flow velocities ranged from 0.064 to 0.34 m/s, which is equivalent to physiological venous and slow arterial blood flow and one to two orders of magnitude above the detection threshold of standard Doppler ultrasound equipment.

CONCLUSIONS:

Translabial color Doppler imaging of the lower urinary tract allows the documentation of fluid leakage from the bladder. It has the potential to become the new imaging standard for urogynecology.
