Evaluation: Verathon BladderScan Prime Plus Bladder Scanner

December 21, 2018 | Evaluations & Guidance


  • The primary purpose of the BladderScan Prime Plus is to calculate an estimate of urinary bladder volume.
  • Contraindications: This device is contraindicated for:
    • Fetal use, or use on pregnant patients
    • Use on patients with open skin or wounds in the suprapubic region, or patients with ascites
  • Major device components include:
    • Console
      • The console contains an ultrasound signal generator, receiver, and processor. It has a color LCD touchscreen user interface that displays patient and facility data, B-mode images, a graphic of the bladder in relation to the ultrasound beam used to guide volume data acquisition, a battery status icon, and a digital readout of bladder volume. A virtual keyboard can be used to enter patient data, facility name, and the date and time. The console has two USB ports and an SD card slot. The system can store saved exams on internal memory; and patient data, including the B-mode images and volume estimations, can be exported to the provided USB drive or SD card. The scanner has onboard software to calculate cost savings based on bladder catheterizations and urinary tract infections avoided by the use of the device. Access to saved patient data and exam results can be restricted with a user-defined security code.
      • The 12.5 × 22.7 × 25.9 cm (4.9 × 8.9 × 10.2 in) console weighs 1.8 kg (3.9 lb) and can be used while hand-held, on a tabletop, or when attached to the optional wheeled stand. The console has a 17.8 cm (7 in) color LCD touchscreen display, a built-in handle used to transport and position the scanner at the bedside, and a removable, rechargeable lithium-ion battery. The touchscreen provides controls to perform a pre-scan, acquire volume data, save data, or export data. A removable kickstand is attached to the rear of the console and is used to rest the scanner on a tabletop.
    • Handheld probe (1) The probe contains a transducer that transmits a 2.8 MHz ultrasound signal and receives reflected echoes to determine bladder size, which is used to calculate an estimated bladder volume. Real-time B-mode imaging can be performed in pre-scan mode. In VMODE, the scanner performs an automated 3-D volume acquisition, using 12 equally spaced 2-D, 120° images around the central axis of the transducer. The acquired 3-D data is then used to calculate an estimated bladder volume.
