The Urology Center at CHOC has implemented and evaluated a bladder pressure and volume diary for patients at risk for increased intravesical pressures.
“Patients dependent on clean intermittent catheterization used ruler-based manometry to measure intravesical pressures before leakage or scheduled drainage at home,” said Dr. Antoine Khoury, chief of pediatric urology. Patients were asked to record measurements while relaxed in a supine position.
Study results
The study included 30 patients ranging in age from 1 to 20, with a mean age of 10.
“Home pressures measured at maximal clean intermittent catheterization volume and mean bladder pressure/volume diary pressures were most reliable in predicting urodynamic pressures greater than 30 cm water (AUC 0.93 and 0.87, respectively). Home pressures measured at maximal clean intermittent catheterization volumes less than 20 cm water were associated with normal bladder pressures (less than 30 cm water) on urodynamics, with a sensitivity of 100% and a specificity of 80%,” said Dr. Khoury.

A bladder pressure/volume diary helps patients monitor pressure at home and reduces the need for frequent video urodynamics (VUDS) or urodynamics (UDS). As a complementary tool to urodynamics, it provides early detection for high bladder pressures that have the potential to cause kidney damage and renal failure.
CHOC Children’s Hospital was named one of the nation’s best children’s hospitals by U.S. News & World Report in its 2024-25 Best Children’s Hospitals rankings and ranked in the urology specialty.
