Fluid weight uroflowmetry in women

This study evaluates fluid weight uroflowmetry as a screening technique for urogynecologic conditions. Sixty women with no known pathologic condition volunteered for the evaluation of normal uroflowmetric parameters and curve patterns. Forty were menstruating cyclically, and 20 were postmenopausal. The parameters studied included: (1) total voided volume, (2) flow time, (3) peak flow rate, and (4) time to peak flow rate. In addition, uroflowmetric tracings were classified according to their patterns of configuration into: (1) normal, (2) multiple peak, and (3) interrupted. The parameters studied showed no difference in the two normal groups. A wide range of values was observed. Neither age, parity, weight, height, nor menstrual cycle phase affected the data. Values obtained from patients with idiopathic instability of the detrusor muscle, sensory urgency, and stress urinary incontinence did not show differences or trends. Seventeen percent of the tracings of the normal population group showed either multiple peak or interrupted patterns. Patients with sensory urgency (p < 0.001) had a higher incidence of multiple peak and interrupted flow rate patterns.
