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
