如持續出現「下尿路症狀」,包括:尿頻(日間排尿次數過多)、夜尿(晚間需起床排尿)、尿急(難以忍受的尿意)、排尿困難、尿流細弱或感覺排尿不清,均可能是前列腺增生、膀胱功能障礙或尿道狹窄的徵兆,建議進行專科評估以找出成因。

Q2:男士應在甚麼年齡開始進行「前列腺健康檢查」?
Details

一般建議 50 歲或以上的男士,應定期進行前列腺健康評估。如有前列腺癌家族病史,則建議提早至 40 至 45 歲開始。基本的泌尿專科檢查通常包括前列腺特異抗原(PSA)血液測試及前列腺超聲波掃描,以評估良性增生或惡性腫瘤的風險。

Q3:泌尿科的「超聲波檢查」主要評估哪些器官?
Details

超聲波檢查是一種無創、無輻射的影像診斷工具。在泌尿科中,它主要用於評估腎臟(檢查有否積水、結石或腫瘤)、膀胱(測量殘餘尿量、檢查壁厚度)以及前列腺(測量體積大小)的結構狀況。

Q4:如何準確診斷「腎結石」?單靠驗尿足夠嗎?

驗尿只能發現是否有血尿或感染,不足以確診結石。要準確判斷結石的位置、大小及數量,通常需要配合影像檢查。腹部X光可顯示大部份含鈣結石,但對於X光不顯影的結石或較細小的結石,則需透過泌尿系統電腦掃描才能進行最精準的診斷。
