[The application of a radionuclide technique for uroflowmetry and determination of residual urine in gynecology (author's transl)].

The micturition of 74 female patients with different disturbances of bladder voiding was studied using 99mTc-DTPA and a gamma camera connected to a cinescintigraphic system and a small computer. The urinary flow and the residual urine were determined from the voided urine volume and from the time-activity curves and the residual counting rate respectively recorded over the bladder region. The values of normals are compared with those found in different types of incontinence and neurogenic micturition disorders. The method provides important parameters of the dynamics of bladder voiding without unphysiologic manipulations. The costs are very low if the standard equipment of a nuclear medicine department can be used.
