Urethral pressure profile using microtip catheter in females.

The use of urethral pressure profilometry in the clinical investigation of dysfunction of the female lower urinary tract is discussed. Included is a description of the use of two-channel microtip profilometry in the urethral syndrome, urinary retention, detrusor hyperreflexia, stress incontinence, and normal females. Dual-channel profilometry improves the diagnostic accuracy of urethral profile studies and aids in the understanding of lower urinary tract pathophysiology.
