Why It Matters
A 71-year-old man experienced worsening symptoms of frequent nighttime urination, difficulty urinating, and post-urination dribbling, initially attributing them to age-related prostate enlargement. Further examination revealed high PSA and PHI levels, leading to a diagnosis of stage II prostate cancer.

〔記者歐素美/台中報導〕 71歲江姓男子長期飽受夜尿頻繁、排尿不順與尿後滴瀝困擾,原以為只是年紀增長導致攝護腺肥大,近日症狀加劇才到醫院就醫檢查,經衛生福利部豐原醫院泌尿科主任林德祺檢查攝護腺特異抗原(PSA)與攝護腺健康指數(PHI),數值分別高達12.4與113,進一步透過攝護腺MRI與切片檢查,確認為第二期攝護腺癌,家屬擔心傳統手術可能帶來尿失禁與性功能受損,影響生活品質,選擇無傷口的「海扶刀」治療,住院2天即返家,恢復良好。
林德祺提醒,攝護腺癌早期幾乎沒有明顯症狀,容易與攝護腺肥大混淆,當腫瘤壓迫尿道時,可能出現尿急、尿流變細、排尿不乾淨與夜尿增加,以及血尿、排尿疼痛或精液帶血,甚至轉移至骨骼,引發背痛或骨折。

根據統計,攝護腺癌第1、2期5年存活率接近100%,第3期約95%至100%,但第4期轉移後約30%至32%,建議50歲以上男性或高風險族群應定期接受PSA抽血與直腸指診,並透過均衡飲食,如攝取茄紅素與十字花科蔬菜、減少高脂飲食、規律運動與體重控制,降低罹癌風險。
林德祺表示,「海扶刀」是利用類似「放大鏡聚光」原理,將高能量超音波精準聚焦於腫瘤,在數秒內產生約65°C至85°C高溫,使癌細胞凝固性壞死,如同將腫瘤「煮熟」,最大優勢在於定位精準,可避開控制勃起的神經血管束與尿道括約肌,有助降低術後失能風險,相較傳統手術可能影響排尿與性功能,海扶刀屬無創治療,體表無傷口、恢復期短,更有機會兼顧治療效果與生活品質。
江男出院後持續追蹤,顯示PSA從12.4大幅下降至0.6,不僅排尿狀況明顯改善,也成功保留性功能且無漏尿困擾。林德祺指出,海扶刀屬於「無創燒灼術」,具備「無傷口」、「精準保功能」及「快速恢復」三大優勢,主要適用於第1、2期等早期攝護腺癌或局部復發患者,實際治療仍須由專科醫師依個別病情評估。
