目的 探討彩色多普勒超聲診斷膀胱破裂的診斷價值,以提高膀胱破裂的超聲診斷水平。 方法 回顧性分析2002年1月－2011年9月術前行彩色超聲檢查診斷膀胱破裂并經手術證實的5例患者資料，下腹加壓檢查和經導尿管注水試驗檢查作為超聲判斷有無膀胱破裂的重要檢查方法。 結果 5例均為腹膜外型膀胱破裂,彩色多普勒血流顯像明確診斷4例，漏診1例，超聲檢查是診斷膀胱破裂的有效方法。 結論 彩色多普勒超聲可以作為膀胱破裂的首選檢查技術。Objective To investigate the value of color doppler flow image (CDFI) in diagnosing bladder rupture, in order to promote the ultrasound diagnosis for the disease. Methods We retrospectively analyzed the medical data of 5 patients with bladder rupture diagnosed by CDFI before operation and confirmed by surgery. Pressing the lower abdomen and injecting water through catheter were the main examination methods for CDFI in diagnosing bladder rupture. Results All the 5 cases were bladder rupture of extraperitoneal type. Four were diagnosed with CDFI, and 1 was misdiagnosed. The ultrasonic examination was an effective technology in diagnosing bladder rupture. Conclusion CDFI may be regarded as the first diagnostic technology for bladder rupture.
