Six continent and 4 incontinent females were examined by a combined technique of simultaneous urethrocystometry and rapid X-ray-film exposures. The study confirmed that pressure changes occurring in the urethra and bladder at initiation of voiding were not caused by artefacts of the measuring technique. It was found that the continent females initiated micturition mainly by a rapid decrease in urethral pressure followed by an increase in the bladder pressure. The stress incontinent females strained out the urine without initial urethral relaxation. Since the X-ray-technique did not add any new clinical information about micturition in females the pressure recording technique is recommended for routine investigation of micturition in females.

A technique for video urethrocystography in women is described and evaluated from the results of examinations on 76 subjects. The patients were examined seated in the lateral position and investigations were carried out at rest, and during straining and coughing, micturition and holding-back maneuvers. Special attention was paid to the overall morphology and the position of the bladder base, the bladder neck and the urethra. Apart from the contour of the symphysis, which in some patients was difficult to identify, the various structures were easily displayed. Also the dynamics of the function of the bladder base, the bladder neck and the urethra were visualized. Almost all patients were able to carry out all parts of the examination including micturition without difficulty. TLD dosimeters in the vagina and uterus showed a low radiation dose to the ovaries.
