Magnetic Resonance Urethrography to Assess Obliterative Posterior Urethral Stricture: Comparison to Conventional Retrograde Urethrography With Voiding CystoUrethrography
The Journal of urology, 2009Co-Authors: Myeong Heon Jin, Deuk Jae Sung, Duck Ki Yoon, Je Jong Kim, Du Geon MoonAbstract:Purpose: We prospectively evaluated magnetic resonance Urethrography for depicting obliterative posterior urethral stricture.Materials and Methods: A total of 25 men with a mean age of 48.7 years (range 21 to 72) with complete posterior urethral stricture were studied preoperatively with axial and sagittal turbo spin-echo T2, sagittal T1 and contrast enhanced sagittal T1-weighted images. Of the 25 patients 22 underwent conventional retrograde Urethrography with voiding cystoUrethrography. For magnetic resonance Urethrography aseptic lubricant was infused through the external urethral meatus to dilate the distal urethra up to the stricture. Each imaging result was compared with a surgical specimen or a description of the surgical findings. Measurement errors were analyzed using the Wilcoxon signed rank test. The relationship between true and measured stricture length was evaluated by linear regression analysis.Results: Based on magnetic resonance Urethrography findings 2 patients with a less than 1 cm stri...

Obliterative Urethral Stricture: MR Urethrography versus Conventional Retrograde Urethrography with Voiding CystoUrethrography
Radiology, 2006Co-Authors: Deuk Jae Sung, Du Geon Moon, Yun Hwan Kim, Sung Bum Cho, Nam Joon Lee, Jung Hyuk Kim, Kyoo Byung Chung, Je Jong KimAbstract:Institutional review board approval and informed consent were obtained. The purpose of the study was to prospectively evaluate magnetic resonance (MR) Urethrography for the depiction of obliterative urethral stricture. Twelve patients with obliterative urethral stricture were examined preoperatively with T2-weighted, T1-weighted, and contrast material–enhanced T1-weighted MR imaging of a urethra distended with sterile lubricating jelly. Ten of the 12 patients were examined with conventional retrograde Urethrography (RGU) combined with voiding cystoUrethrography (VCUG) prior to MR imaging. Each imaging result was compared with either a surgical specimen or a description of the surgical findings to determine which method allowed accurate estimation of stricture length. MR measurements of stricture length demonstrated significantly lower errors (P .05, respect...

CT voiding Urethrography and virtual urethroscopy: preliminary study with 16-MDCT.
American Journal of Roentgenology, 2005Co-Authors: Chen-pin Chou, Jer-shyung Huang, Huay-ben Pan, Fong-dee Huang, Chien-fang YangAbstract:OBJECTIVE. The purpose of this study was to demonstrate CT voiding Urethrography and CT virtual urethroscopy. Fourteen CT voiding Urethrography examinations on 13 men (mean age, 30 years) were prospectively performed with 16-MDCT. The clinical diagnoses of those patients included urethral injury, urethral stricture, and hypospadia. The CT voiding urethrogram was obtained with transverse CT of the voiding, contrast-filled urethra and display of 2D multiplanar and 3D virtual images.CONCLUSION. The full urethral structure was clearly shown by CT voiding Urethrography and virtual urethroscopy in all patients. The results of CT voiding Urethrography and conventional methods correlated closely with the urethral diseases being imaged.
