Portable ultrasound accurately measures bladder volume in stroke patients, offering a safe and effective noninvasive alternative to catheterization for bladder management and continence care.

Area of Science:

  • Urology
  • Geriatrics
  • Medical Imaging

Background:

  • Urinary retention is a common complication in stroke patients.
  • Accurate bladder volume assessment is crucial for effective bladder management.
  • Catheterization, while effective, carries risks of infection and discomfort.

Purpose of the Study:

  • To compare the accuracy of portable ultrasound for bladder volume measurement against bladder catheterization.
  • To evaluate the interobserver reliability of ultrasound bladder volume measurements.

Main Methods:

  • A prospective study was conducted over 13 weeks on stroke unit patients.
  • Bladder volume was measured using both portable ultrasound and urinary catheterization when retention was suspected.
  • Ninety ultrasound examinations were performed, with 70 by one nurse and 20 independently by two nurses.

Main Results:

  • A highly significant correlation (r = 0.983) was found between ultrasound bladder volume measurements and actual catheterized volumes.
  • Excellent interobserver reliability was demonstrated for ultrasound measurements.
  • Ultrasound measurements were found to be safe, effective, and inexpensive.

Conclusions:

  • Portable ultrasound is a highly accurate and reliable method for noninvasive bladder volume assessment in stroke patients.
  • Ultrasound serves as a valuable adjunct to preventive bladder and continence management in this population.
  • This noninvasive technique reduces the need for catheterization, potentially lowering complication rates.
