Dynamic urethrocystography in women.

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.
