Suburethral diverticulum: classification and therapeutic considerations

The records of 70 patients with a suburethral diverticulum were reviewed. Cases were classified according to their anatomic site of origin in an attempt to rationalize the appropriate therapeutic approach. It is suggested that suburethral diverticulum arising in the lower third of the urethra be preferably treated by marsupialization with tissue excision for histologic confirmation, and those diverticula arising in the upper two thirds of the urethra be treated by excision. In those cases in which multiple diverticula are suspected, an anterior vaginoplasty should be carried out in an attempt to reduce the morbidity associated with excision only.
