title: Ultrasonographic Features of Female Urethral Diverticula: A Retrospective Study of 25 Patients.
abstract: This article summarizes the ultrasonographic features of female urethral diverticula on biplane transrectal ultrasound (B-TRUS).
  
  
  
  A retrospective study was performed with 25 consecutive women who were diagnosed and treated as having urethral diverticulum (UD) between January 2012 and March 2016. All the patients were preoperatively evaluated using B-TRUS. The number, location, configuration, size, and type of the UD on B-TRUS were assessed.
  
  
  
  Twenty-eight diverticula were found on B-TRUS. Twenty-two patients had single diverticulum, whereas the other 3 had double diverticula. The locations included proximal (14%), mid (46%), and distal (40%) urethra. In transverse section, the configuration presented as round or oval (46%), and horseshoe-like or circumferential (54%). The maximal diameter of the 28 diverticula ranged from 3 to 48 mm. The types contained simple UD (36%) and complex UD (64%). Color blood flow signal could be detected in the septa, cystic wall, and solid mass, whereas negative in other areas inside the UD.
  
  
  
  Various sonographic characters of female UD could be observed during the evaluation, including single or multiple diverticula, different sites, diverse shapes, and septa, calculi, or neoplasm inside diverticulum, all of which could be clearly displayed on B-TRUS.
