摘要

榮民總醫院自1980年4月至1983年4月間，具有完整病歷記錄的58例膀胱癌病人曾接受超音波檢查，癌病可能侵犯膀胱壁及鄰近組織，導致膀胱壁不規則(irregularity)，膀胱變形(deformity),膀胱容量(capacity)減少及膀胱外癌細胞的蔓延(extraresical spread of tumor)。本文係就其受侵犯的程度，做回顧性之分期，並將此結果與外科手術所見加以比較。這58例中，男性54例女性4例，年齡分佈自25歲至82歲，其中以60至69歲最多（佔44%），臨床症狀以無痛性血尿為主。回顧性分期之結果，發現未曾手術過的病例其準確率為80.9%，而經手術後的病例準確率只有27.3%。

From April 1980 to April 1983, 53 cases of bladder cancer which had been examined by the gray-scale ultrasound, were analyzed according to the involvement or invasion of the bladder wall and adjacent soft tissue. Ultrasonograms of these tumors were estimated on the basis of the bladder wall irregularity, bladder deformity, bladder capacity and extravesical spread of tumor.
The result of sponographic staging were correlated with operative findings and was 80.9% accurate. For new untreated cases, overstaging and understaging were found in 19.1% respectively.
In these 58 cases, male to female ratio was 54 to 4,44% of the patients were in their sixth decade, the most common clinical symptoms were painless gross hematuria.
Accurate preoperative staging of bladder cancer is necessary for the selection of appropriate treatment, and sonography is the only absolutely non-invasive itaging method. Therefore, it appears to us that the ease, wide accessibility and relating low cost of ultrasound should make it the preferred modality following cystoscopy in the diagnostic studies of a bladder cancer.
