STRESS LEAK POINT PRESSURE - A DIAGNOSTIC-TOOL FOR INCONTINENT CHILDREN

The stress leak point pressure is the lowest bladder pressure at which leakage occurs during prompted increases in intra-abdominal pressure. The stress leak point pressure is distinct from the simple bladder leak point pressure and can be determined using simple urodynamic equipment without fluoroscopy. In 15 incontinent girls and boys 2.5 to 15 years old the mean stress leak point pressure was 54.7 cm. water (range 11 to 100), whereas the mean leak point pressure was 19.9 cm. water (range 5 to 50, paired t test p <0.0001). The stress leak point pressure is a useful diagnostic tool that provides specific data on bladder neck and proximal urethral function.
