Abstract:
OBJECTIVES: To study CT finding and the value of retrograde cystography CT scan in the diagnosis of bladder diverticulum. MATERIAL AND METHODS: The study was performed in accordance with the regulations of the local institutional review board and ethics committee. Written, informed consent was obtained from all patients before the examination and enrolment into the study. 70 patients with bladder diverticulum (mean age 62 years; range 43-78 years, 39 males and 31 females) were examined, including ultrasound, X-ray cystogram, plain scan CT, contrast enhanced CT, the retrograde cystogram CT, compared the accuracy of these examination in diagnosis of bladder diverticulum
…and observed size, location, shape, opening of bladder diverticulum. Selection and diagnosis of all patients of enrolled into the study were confirmed by cystoscopy. But, this result was double-blind to the resident doctors for them examined and diagnosed. Three examination were selected for each patient, the first examination was random, the second was the plain scan CT, the third was the retrograde cystogram CT, all patients were must examined by the plain scan CT and retrograde cystogram CT. RESULTS: In 70 patients, 22 case were examined by ultrasonic, 15 cases were accurate diagnosed, 4 cases were examined by X-ray cystography, 3 cases were accurate diagnosed, 70 cases were examined by plain scan CT, 48 cases were accurate diagnosed, 17 cases were examined by contrast enhanced CT, 12 cases were accurate diagnosed, 70 cases were examined by retrograde cystography CT, 70 cases were accurate diagnosed, retrograde cystography CT well showed the size, location, shape, opening of the bladder diverticulum, while others examination showed these were poor. CONCLUSIONS: Retrograde cystography CT could accurately diagnose bladder diverticulum, clearly showed the size, location, shape and opening of bladder diverticulum, could provide accurate and detailed information for clinical, thus it is a simple, effective and economical method of the diagnosis of bladder diverticulum.
