Background: Computerized tomography(CT) is the method of choice for establishing patients with abdominal and/or pelvic trauma. However, the sensitivity of CT for detecting bladder rupture has been questioned. We investigated the roles of CT as the initial evaluation of abdominal and pelvic trauma in diagnosis of bladder rupture. Methods: We reviewed the medical records and radiographs of 53 patients with bladder rupture for last 5 years. And among them, all radiographs of 30 patients who underwent both CT and retrograde cystography were evaluated independently by two urologists who had no knowledge of the patients' final diagnosis. Results: Among 30 patients, all of patients were correctly diagnosed by retrograde cystography, but the CT diagnosis was correct in only 23 patients(76.7%), who were 17 patients(85.0%) with intraperitoneal rupture and 6 patients(60%) with extraperitoneal rupture. And of the 7 patients who were negative by the CT, all showed the sign of inadequate bladder distension. Conclusion: We suggest that CT, if properly performed with adequate bladder filling, is as sensitive for detection of bladder injuries as conventional cystography. Especially, in trauma patients with hematuria and suspected other organ injury, CT-cystography with retrograde filling may be as accurate as conventional cystography and obviate the need for an additional plain film cystography.

The method for rapid determination of crotamiton in ointment and action was established by using reverse phase high performance liquid chromatography. First, crotamiton in ointment (or lotion) was extracted with methanol and 20㎕ portion of the extracted solution was injected into the column. The effluent was monitored by an ultraviolet detector at 254 um. On a μ-Bondapak C_18 column(3.9 mm i. d x 30cm) with an eluent of MeOH/H_2O=55/45, a sufficient separation of crotamiton, preservatives, and minor components was obtained. The proposed procedure provided an accurate, sensitive, and rapid estimation, and a good , ability suggesting a suitable assay method for crotamiton in pharmaceuticals.
