To demonstrate the reproducibility of AC versus WP catheters when measuring pressures during voiding pressure studies in urodynamics (UDS).
Female patients enrolled above the age of 21
Complaints of lower urinary tract symptoms and were recommended urodynamic studies for further evaluation of symptoms.
Commercially available AC catheter was utilized to form a dual catheter to simultaneously read water and air pressures within the bladder 1 cm apart
Water-filliing channel serves both as bladder filler and water pressure sensor to an external transducer on a Laborie urodynamics machine.
A comparative analysis was performed on the maximum peak pressures during the voiding pressure study (VPS).
Both air charged catheters and water perfused catheters are comparable in their pressure readings during maximum pressure during a voiding pressure study.
