Bladder Ultrasound Indications
- Concern for postrenal acute kidney injury
- Voiding dysfunction
- Estimation of bladder volume (post-void residual)
- Confirmation of proper urinary foley catheter placement
- Troubleshooting malfunctioning foley catheter
Patient and Machine 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.
