Pad test with fixed bladder volume in urinary stress incontinence.

A pad-weighing test of urinary stress incontinence during a set program of physical exercises is presented. The test was begun at a fixed bladder volume (75% of maximum capacity) and was repeated once. The duration of the exercises was approx. 15 min. Leakage was greater in the second test, but statistical analysis showed highly significant intraindividual correlation between the two amounts. Degree of leakage was not correlated to subjective assessment of incontinence. The test can be done as part of a routine urodynamic investigation.
