Ultrasonic measurement of residual urine: a method requiring no catheter
International Urology and Nephrology
|January 1, 1981
Abstract:
Residual urine was measured with the two-dimensional and the gray-scale equipments (Kretz-Technik) in 26 cases each. The results were checked by catheterization. The difference between the ultrasonographic and the catheter values was 20 to 40 ml for the two-dimensional, but only 5 to 10 ml for the gray-scale apparatus. Ultrasonography is regarded as a reliable and entirely harmless procedure, suited for the measurement of residual urine.
