On the basis of data obtained in previous experimental investigations, the application of a new physical entity, "strain" (sigma), was evaluated in bladder dynamics. In this preliminary study 12 cases of urodynamically evaluated subjects are reported; the significance of the traditional P(V) curves is critically compared with the new sigma (V) curve, proposed by the authors.
The literature is reviewed and the applicability of Laplace's law to the urinary bladder considered as a sphere is critically discussed. Experiments were performed on live rabbits, on isolated bladders and on rubber balloons to study vesical adaptation and response to filling. From the data obtained, the authors propose "strain", rather than tension, as a characteristic quantity of bladder function and indicate the possible application of these experimental results clinically.
