[Uroflowmeter, a device for measuring urine volume and urination rate].

The paper deals with the design and construction of a float-type uroflowmeter that is characterized by higher reliability, precision, validity of measurements. The characteristics of the device have been improved by excluding a sliding contact which operates in the corrosive medium, by applying a primary gauge whose output signal is proportional to the instantaneous value of urinary debit.

[Device for measuring the miction output].

An apparatus enabling it to register the micturition rate both under natural conditions and during catheterization of the urinary bladder is recommended for gauging the miction output. The method of measuring the miction (urinary) output is very simple. Formulas listed in the paper permit one to calculate the relative urethral resistance from the amounts of miction and cetherterized urinary outputs.
