ABSTRACT
OBJECTIVES: To evaluate the utility of virtual cystoscopy (VC) performed with CT urography in patients being studied under gross hematuria or patients being followed-up after a previous bladder cancer and compare the results with those obtained with gold standard technique (optical cystoscopy). METHODS: Retrospective study of 117 patients who were referred for VC by the Urology Department between May 2014 and May 2015. Those patients presented with gross hematuria or they were previously treated patients from bladder cancer being followed up. These patients were evaluated with MDCT and virtual cystoscopy after distending the bladder with air. The results were compared with those obtained with optical cystoscopy which was performed no more than a week after. RESULTS: The global sensitivity and specificity of VC were 81,8 and 92,1%. Aditional findings detected in CT urography were an aortic dissection, urinary lithiasis and colonic metastasis. CONCLUSION: VC seems an useful technique in the diagnosis and follow-up for bladder cancer with a good correlation with OC. The main limitations are the impossibility of biopsy during the procedure and the detection of erythematous lesions. Collateral findings can be detected performed with CT urography although the high radiation exposure does not recommend their combined use.

The StarClose(®) arterial device (Abbot Vascular Devices, Abbot Laboratories, Redwood City, CA, USA) rapidly seals a femoral artery puncture by means of a nitinol clip in the adventitia of the artery. It is a safe and effective device, with advantages as regards manual compression, but is not free of complications. We present two cases with complications after using a StarClose(®) vascular device.

Acute iodide sialadenitis is a rare adverse reaction to iodinated contrast that causes self-limited salivary gland swell-ing. Its pathogenesis is still unclear, although kidney failure may be a risk factor. The diagnosis is initially clinical but angioedema, infections and lithiasis should be included in the differential diagnosis. No treatment or prophylaxis was proven to be beneficial. Although its prognosis is benign, associated complications have been reported. We report a case of 68-year-old man with swelling of the submandibular salivary glands after the administration of iodine-based contrast media during an abdominal computed tomography examination. Because of the widespread use of iodinated contrast enhanced imaging and interventional techniques, clinicians should be aware of this issue.
