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.
