Study Notes
Ultrasound Imaging of the Urinary Bladder
- Indications for ultrasound imaging of the urinary bladder include:
- Dysuria or frequency of micturition
- Hematuria (after bleeding has stopped)
- Recurrent infection (in adults; acute infection in children)
- Pelvic mass
- Retention of urine
- Pelvic pain
Preparation of the Patient
- The bladder must be full during the ultrasound examination
Normal and Abnormal Urinary Bladder
- A normal bladder appears as a smooth, evenly stretched structure
- Columns within the bladder indicate a possible ureterocele, which may be bilateral but rarely symmetrical
- Large/overdistended bladder:
- Bladder walls will be smooth and evenly stretched, with or without diverticula
- Measurements can confirm suspected overdistension
- Always check the ureters and kidneys for hydronephrosis
- Ask the patient to empty the bladder and rescan to see if it is completely empty
- Common causes of bladder distention include:
- Enlargement of the prostate
- Urethral stricture in the male
- Urethral calculus in the male
- Bruising of the urethra in the female ("honeymoon urethritis")
- Neurogenic bladder from damage to the spinal cord
- Small bladder:
- May be due to cystitis, which prevents the patient from holding urine and causes frequent and painful micturition
- May be due to damaged or fibrosed bladder walls, reducing bladder capacity
- May be due to other causes, such as urethral valves or diaphragm in newborn infants, or cystocele in some patients
