title: Urodynamic catheter moisture sensor: A novel device to improve leak point pressure detection.
abstract: High-quality urodynamic studies in patients with neurogenic lower urinary tract dysfunction are important, as UDS may be the only reliable gauge of potential risk for upper tract deterioration and the optimal tool to guide lower urinary tract management. Reliance on direct visualization of leakage during typical UDS remains a potential source of error.
  
  
  
  Given the necessity of accurate leak point pressures, we developed a wireless leak detection sensor to eliminate the need for visual inspection during UDS.
  
  
  
  A mean decrease in detrusor leak point pressure of 3 cm/H2 0 and a mean 11% decrease in capacity at leakage was observed when employing the sensor compared to visual inspection in children undergoing two fillings during a single UDS session.
  
  
  
  Removing the visual inspection component of UDS may improve accuracy of pressure readings. Neurourol. Urodynam. 35:647-648, 2016. © 2015 Wiley Periodicals, Inc.
