Imaging of the male urethra for stricture disease 总被引:2,自引:0,他引:2
Imaging of the urethra for suspected stricture disease should initially consist of conventional imaging with a dynamic RUG. It is easy to perform and detects clinically relevant strictures involving the anterior urethra and those with extension into the membranous urethra. Additional studies, including antegrade imaging, sonographic urethrography, and MRI are best used in conjunction with RUG as clinically indicated to better define the extent of disease and assist in guiding reconstruction. Post-operatively, VCUG is appropriate to evaluate complete healing and adequacy of repair. Sonourethrography is a simple technique that provides a dynamic, precise assessment of anterior urethral strictures. It is best employed as a staging study in men with known symptomatic strictures in whom the need for operative therapy is clear. For short bulbar strictures ultrasound is more accurate in measuring stricture length than conventional radiographic RUG and is therefore helpful in determining whether to excise or graft. For long or complex strictures assessment of the stricture's diameter may be helpful in determining flap width or in identifying the focal urethral segments to be excised. The simplicity, precision, and availability of sonography along with the absence of radiation exposure make sonourethrography a valuable staging tool for the reconstructive urologist. MRI is valuable for defining the distorted pelvic anatomy that is frequently associated with posterior urethral strictures resulting from trauma. By determining the location of the prostate and the length of the prostatomembranous defect, MRI may help determine whether a transperineal or transpubic approach for reconstruction is necessary. 相似文献

A total of 17 patients with suspected stricture disease underwent conventional retrograde urethrography and sonourethrography. When the length of the stricture as assessed by each imaging modality was compared to measurements at open urethroplasty in 7 patients, sonourethrography was consistently more accurate. Distension of the urethra with saline during the ultrasound examination enabled classification of the degree of spongiofibrosis, which was confirmed by full depth biopsy in 5 patients. Sonourethrography cannot adequately image the posterior urethra, even when the transcrotal approach is used. However, because it is a dynamic 3-dimensional study and can be repeated without risk of radiation exposure, sonourethrography is preferable to radiographic retrograde urography to evaluate patients with suspected anterior urethral strictures. 相似文献

PURPOSE: We compared the clinical relevance of radio urethrography with that of sonourethrography for evaluating male urethral strictures. MATERIALS AND METHODS: From 2002 to 2004, 93 men were referred to our institution for urethral strictures. Patients were evaluated by conventional voiding cystourethrography, retrograde urethrography, and gray scale and color Doppler sonourethrography. For sonourethrography the extended field of view technique was used to obtain 1 image of the whole anterior urethra. In all cases the urethra was evaluated cystoscopically or at open surgery. Radio urethrography and sonourethrography findings were compared with cystoscopy or surgery findings. RESULTS: All strictures were evaluated and treated cystoscopically with visual internal urethrotomy (34%) or at open operation (66%), which allowed comparison of the ability of each study to predict operative stricture length. Sonourethrography correctly identified the stricture and its site in all cases, whereas radio urethrography yielded 2 false-negative results. There was a significant difference between stricture length measured by radio urethrography compared to that measured by sonourethrography (correlation coefficient 0.72 vs 0.92, p<0.005). Mean+/-SD stricture length measured by radio urethrography was 1.5+/-1.3 cm and by sonourethrography it was 2.1+/-0.9 cm. Comparison of radio urethrography and sonourethrography stricture length with operative lengths demonstrated a good correlation in the penile urethra (correlation coefficient 0.91 vs 0.98), whereas a poor correlation was found in the bulbar urethra (correlation coefficient 0.65 vs 0.92). CONCLUSIONS: Gray scale and color Doppler sonourethrography using the extended field of view technique with a Siemens Sonoline Elegra is a promising tool for defining male urethral strictures. It seems to be superior to radio urethrography for treatment planning. 相似文献

Accurate imaging of urethral strictures is critical for preoperative staging and planning of reconstruction. The current gold standard, retrograde urethrography (RUG), allows for accurate diagnosis, staging, and delineation of urethral strictures, and remains a cornerstone in the management of urethral stricture disease. In complex situations, the RUG can be combined with voiding cystourethrogram (VCUG) in order to better visualize the posterior urethra or complex distraction defects. Direct visualization of the stricture by cystoscopy, either retrograde or antegrade, can provide additional information as to the location and appearance of stricture, as well as precise location on fluoroscopic imaging. Sonourethrography (SU) is a useful adjunct to allow for three-dimensional assessment of stricture length and location, and can be a useful intraoperative assessment tool, however, its use remains limited to a second-line setting. Cross-sectional imaging in the form of computed tomography (CT) or magnetic resonance urethrography can provide additional three-dimensional information of anatomic structures and their relations, and can serve as a useful adjunct in complex clinical scenarios. 相似文献

Sonographic staging of anterior urethral strictures 总被引:5,自引:0,他引:5
PURPOSE: Although radiographic retrograde urethrography has traditionally been the gold standard for imaging the anterior urethra, sonourethrography has proved to be precise and effective for evaluating urethral strictures. We review the evolution of sonourethrography and demonstrate its practical contemporary applications. MATERIALS AND METHODS: We performed literature reviews on MEDLINE and chart reviews of our patient records from 1988 to 1998. RESULTS: Sonourethrography measures stricture length in the bulbar urethra more accurately than conventional retrograde urethrography. Spongiofibrosis is manifested sonographically by a lack of urethral distensibility during retrograde instillation of saline solution. Posterior shadowing is noted in severe posttraumatic cases. Sonographic staging before treatment of complex or reoperative anterior strictures elucidates complicating features, such as calculi, urethral hair, false passage and stent encrustation. CONCLUSIONS: Sonographic staging of anterior urethral strictures offers clinically important information that may be useful in guiding reconstructive therapy. 相似文献

Summary A total of 23 patients with bulbomembranous urethral strictures (16 after pelvic fractures, 4 following direct perineal trauma, 3 after catheter drainage) were treated with a perineal one-stage anastomotic urethroplasty. The length of the stricture did not exceed 2 cm. The overall final success rate amounted to 95.6%. The one-stage perineal approach is recommended for short strictures of up to 2 cm in length, if mobilization of the distal urethra is possible and the periurethral scar tissue can be resected. 相似文献

OBJECTIVE: To compare the clinical relevance of retrograde urethrography (RUG) and magnetic resonance (MR) urethrography in evaluating male urethral strictures. METHODS: Between January and April 2004, 20 men were referred to our institute for management of urethral strictures. The patients were investigated by conventional RUG and multiformat MR urethrography. The patients were examined by urethroscopy under anesthesia to be followed by definitive endoscopic or open operative intervention. The radiologic data were compared by endoscopic as well as operative findings in all the patients. RESULTS: Ten patients were managed by visual internal urethrotomy (VIU) and two by dilatation under anesthesia; two showed normal urethral caliber. Four patients required open urethral reconstructive procedures. Two patients underwent radical cystectomy and cutaneous diversion because of associated bladder or urethral malignancy. Although overall accuracy for diagnosis of urethral strictures was equal between both modalities (85%), MR urethrography provided extra clinical data in seven patients (35%). It was superior to RUG in judging the urethral stricture length in three patients, diagnosing a urethral tumor in one, detecting associated bladder mass in one, characterizing the site of urethra-rectal fistula in one, and accurately delineating the proximal urethra in the last patient. Unlike RUG, MR urethrography provided adequate information about the degree of spongiofibrosis in all patients. CONCLUSION: MR urethrography is a promising tool for defining male urethral strictures and can provide extra guidance for treatment planning that cannot be obtained with RUG. 相似文献
