Uroflometry in urological diagnosis.

The automatic recording uroflometer is a simple office instrument which provides an objective record of the rate of voiding. It has proven value as a diagnostic aid in the evaluation of obstructive lower urinary tract problems and in neurotic bladder disorders. Differential uroflometry is used to make relative appraisals of the forces of expulsion of urine and of resistance to the flow of urine through the urethra. It is accomplished by measuring urine flow rate through a catheter of standard size and by comparing this with urine flow rate through the urethra. When used in conjunction with other diagnostic methods, uroflometry adds to the accuracy of urological assessment of a patient.
