Imaging of the female urethra

Female urethral pathology can be challenging to diagnose clinically due to non-specific symptoms. High-resolution MRI has become a powerful tool in the diagnosis of urethral lesions and staging of malignancy. Additionally, dynamic MRI, fluoroscopy or ultrasound can evaluate for pelvic floor prolapse and the effectiveness of surgical interventions. This article will review the imaging features of common benign and malignant conditions of the female urethra including diverticula, benign cystic and solid lesions, malignancy, surgical slings, and injection of bulking agents.
