We report a 28-year-old man who presented with hematuria and intermittent flank pain. Conventional CT urography showed mild left hydronephrosis and an undetermined lesion in the left ureter. By virtual CT ureteroscopy, a fibroepithelial polyp (FEP) was preoperatively diagnosed. The patient had segmental resection of the ureter and pathological proof of FEP was obtained.
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.
OBJECTIVE: A 26-year-old woman presented with urinary frequency. Findings were negative on voiding cystourethrography. Cystourethroscopy failed to reveal a urethral diverticulum. A new method of virtual CT urethroscopy was performed using a 16-MDCT scanner. The orifice of the diverticulum was identified clearly on 3D virtual urethroscopy. Intraoperatively, the diverticulum was identified, with the orifice location compatible with that seen on virtual urethroscopy. CONCLUSION: Virtual CT urethroscopy provides more information than conventional urethral examinations and is less invasive than conventional urethroscopy.
Chronic pelvic pain is a common gynecologic complaint, sometimes without any obvious etiology. We report a case of pelvic congestion syndrome with chronic pelvic pain. The diagnosis can be overlooked by clinical physicians but diagnosed using multi-detector row computerized tomography. This method seems to be an effective and non-invasive imaging modality.
