Combined dynamic studies of the bladder and urethra. Report of a method.
The authors report a method of complex urodynamic investigation. The intravesical pressure, the intrarectal pressure, the electronically computed detrusor pressure, the urinary flow and the electromyography of the anal and urethral striated sphincters are recorded simultaneously with the fluoroscopic image on 16 mm film using the kinescopic procedure. The intravesical pressure is measured per urethram. The routine examination method is described. The authors consider that the use of 16 mm film has advantages in comparison to videotape recordings. The installation was made out of existing materials except for the electronic mixing device, which was created in the research laboratory. Radiation dosis measurements show that even by extensive examination the received radiation dosis does not exceed the exposure of a standard voiding cystourethrogram.
