1. Ultrasound Indications and preparations

Bladder Ultrasound

Bladder Ultrasound Indications

  • Concern for postrenal acute kidney injury
  • Voiding dysfunction
  • Estimation of bladder volume (post-void residual)
  • Hematuria
  • Confirmation of proper urinary foley catheter placement
  • Troubleshooting malfunctioning foley catheter

Patient and Machine Preparation

Patient Preparation

  • The patient will lie supine. You may have the patient bend their knees to soften their abdominal wall.
  • Since you will be scanning in the suprapubic region, make sure to place a towel or sheet to cover the patient’s pelvic area.

Ultrasound Machine Preparation

  • Transducer: Curvilinear Ultrasound Probe or Phased Array Probe. Curvilinear is preferred because its wider footprint allows full visualization of the bladder.
  • Preset: Abdominal or Renal
  • Machine Placement: Place the machine on the patient’s right side so you can scan with your right hand and manipulate ultrasound buttons with your left hand.
