Bladder Base Impressions in Women

The smooth bladder base impression characteristically seen in men with prostatic hyperplasia may also be seen in women. Differential considerations include several unrelated etiologies:

• Asymmetry of the pubic symphysis: Most common cause
• Cystocele
• Urethral diverticulum
• Levator ani impression
• Postoperative change
• Female urethral syndrome
• Vaginal fibromyoma
• Ectopic ureterocele
• Intramural bladder neoplasm
