[The value of the urethral pressure profile in urinary incontinence]

For the differentiation of the incontinence the tonometry of bladder and urethra has become indispensable in diagnostics. The author deals with the advantages of the possibility of a combined examination, the technical performance of the urethra-pressure profile and with the necessity of the same outer conditions. Taking into consideration the functional length of the urethra, the maximum pressure of the urethra as well as the difference between pressure of urinary bladder and urethra in rest and under conditions of stress the criteria for the degrees of incontinence are represented and discussed on the basis of own examinations. Not the position and the absolute length are responsible for the continence, but the relation between the attainable urethra-pressure in contrast to the appearing pressure of the urinary bladder.
