Introduction and hypothesis

The clinical evaluation of anterior vaginal wall masses can present a dilemma, as there are no well-defined pathways for diagnosis and management. Our objective was to evaluate the role and accuracy of preoperative exam and magnetic resonance imaging (MRI) for these masses.

Methods

We identified women with a mass using billing codes for 10?years. We compared data from the preoperative evaluation to postoperative pathology if available.

Results

Analysis after chart review on 47 women was performed. Of the 34 women who had surgery, 28 (82.4%) also underwent an MRI. MRI diagnosis was accurate in 22/28 women compared to histology, inconclusive in 4, and inaccurate in 2. Preoperative diagnosis, including exam, MRI, and cystourethroscopy, had a diagnostic accuracy of 94.1% compared to postoperative diagnosis. The positive predictive value of MRI alone was 91.7%.

Conclusions

Preoperative diagnosis using exam, MRI, and cystourethroscopy have a high diagnostic accuracy for anterior vaginal wall masses.  相似文献

Pooled data from 16 radiology centers were retrospectively analyzed to seek patients with pathologically proven testicular lymphoma and grayscale and color Doppler images available for review. Forty‐three cases were found: 36 (84%) primary and 7 (16%) secondary testicular lymphoma. With unilateral primary lymphoma, involvement was unifocal (n = 10), multifocal (n = 11), or diffuse (n = 11). Synchronous bilateral involvement occurred in 6 patients. Color Doppler sonography showed normal testicular vessels within the tumor in 31 of 43 lymphomas (72%). Testicular lymphoma infiltrates through the tubules, preserving the normal vascular architecture of the testis. Depiction of normal testicular vessels crossing the lesion is a useful adjunctive diagnostic criterion.  相似文献

Men or boys, who present with acute scrotal pain without prior trauma or a known mass, most commonly suffer from torsion of the spermatic cord; epididymitis or epididymoorchitis; or torsion of the testicular appendages. Less common causes of pain include a strangulated hernia, segmental testicular infarction, or a previously undiagnosed testicular tumor. Ultrasound is the study of choice to distinguish these disorders; it has supplanted Tc-99 m scrotal scintigraphy for the diagnosis of spermatic cord torsion. MRI should be used in a problem solving role if the ultrasound examination is inconclusive. The ACR Appropriateness Criteria ? are evidence-based guidelines for specific clinical conditions that are reviewed every two years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.  相似文献

Arterial tumor embolism is a rare occurrence. We report such an embolus causing acute limb ischemia which was the first indication of malignancy in a patient who subsequently proved to have malignant melanoma.  相似文献

Objective

To develop a core curriculum for orthopaedic surgery and to conduct a national survey to assess the importance of 281 items in the curriculum. Attention was focused specifically on 24 items pertaining to the curriculum that are pertinent to the spine.

Study design

A cross‐sectional survey of a random sample of orthopaedic surgeons whose primary affiliation was non‐academic, representing the provinces and territories of Canada

Methods

A questionnaire containing 281 items was developed. A random group of 131 (out of 156) orthopaedic surgeons whose primary affiliation is non‐academic completed the questionnaire. The data were analysed quantitatively using average mean scores, histograms, the modified Hotelling''s T2 test and the Benjimini–Hochberg procedure.

Results

131 of 156 (84%) orthopaedic surgeons participated, in this study. 14 of 24 items were ranked at no less than 3 out of 4 thus suggesting that 58% of the items are important or probably important to know by the end of residency (SD⩽0.07). Residents need to learn the diagnosis and principles of managing patients with common conditions of the spine.

Conclusions

The study shows, with reliable statistical evidence, that orthopaedic residents are no longer expected to be able to perform spinal fusions with proficiency on completion of residency. Is the exposure to surgical spine problems and the ability to be comfortable with operating expectations specific to the fellowship level? If so, the focus during residency or increasing accredited spine fellowships needs to be addressed to ensure that enough spine surgeons are educated to meet the future healthcare demands projected for Canada.  相似文献

Interventional procedures in the upper urinary tract   总被引:1,自引:0,他引:1  
The introduction and acceptance of percutaneous nephrostomy as a safe and effective alternative to surgical nephrostomy served as the impetus for the development and expansion of an ever-increasing number of techniques that are encompassed by the term “interventional uroradiology.” This article reviews many of the non-vascular interventional techniques that have proliferated during the past decade and that are currently used in the kidney, ureter, and perinephric space. The authors emphasize those procedures that are most frequently employed, as well as their own preferences and perspectives on these procedures.  相似文献
