Urethral diverticula: a review and an update.

Likely originating from the periurethral glands, female urethral diverticula (UD) are an uncommon but fascinating clinical entity. UD are variable in their presentation and the diagnosis is sometimes difficult and delayed. Modern imaging modalities such as surface coil and endoluminal magnetic resonance imaging (MRI) have added to the diagnostic armamentarium but have also furthered our understanding of UD. Accurate preoperative characterization of the often complex anatomical patterns seen on these imaging studies including saddlebag and circumferential urethral involvement, as well as complete evaluation of associated voiding dysfunction such as complete evaluation of associated voiding dysfunction such as urinary incontinence often impacts contemporary surgical management.
