The preoperative work-up of female urethral @entity7261 should provide the surgeon with maximum data regarding the anatomy and structure of the diverticulum. Preoperatively, the number of @entity7261 , as well as the location, size, configuration, and communication to the urethra need to be clearly depicted. The objective of this study was to compare the information gained by voiding cystourethrography (VCUG) and positive-pressure double-balloon urethrography ( @entity30689 ), and to verify which imaging modality can better delineate the features of the @entity7261 . Twelve @entity1 with a presumptive clinical diagnosis of a urethral diverticulum underwent VCUG followed by @entity30689 , and the radiological data from each modality were compared. In 4 of 12 @entity1 (33.3%) VCUG completely failed in demonstrating the diverticulum, whereas @entity30689 showed a large complex diverticulum in 2 @entity1 and a distinct mid-urethral diverticulum in 2 @entity1 . In the remaining 8 @entity1 (66.7%) VCUG delineated only the lower part of the diverticulum, whereas @entity30689 depicted a large diverticulum extending beneath the bladder neck in 3 @entity1 and @entity7261 in 5 @entity1 . The sensitivity of @entity30689 and VCUG, in our series, was therefore 100 and 66.7%, respectively. The @entity30689 supplied excellent documentation regarding the location, size, configuration, and communication of the @entity7261 to the urethra in every case, which markedly facilitated surgical excision of the @entity7261 in 9 of 12 @entity1 . Three @entity1 refused surgery and elected conservative treatment. In our experience, VCUG had a low sensitivity as a screening test for the diagnosis of female urethral @entity7261 , and failed to demonstrate properly the major structural characteristics of the @entity7261 , whereas @entity30689 was highly sensitive as a diagnostic tool and supplied excellent anatomical delineation of the @entity7261 .
