腎結石與輸尿管結石是常見的泌尿系統疾病,與水分攝取不足、飲食習慣、生活作息等因素密切相關,夏季為高發季節,但秋季悶熱天氣亦可能導致類似情況發生。

〔記者翁聿煌/新北報導〕新北市30多歲男性,日前因後腰痠痛、悶痛,以為是肌肉拉傷或姿勢不良,先至復健科就醫,後續進一步檢查才發現,疼痛原因竟是腎結石或輸尿管結石所致,泌尿外科醫師提醒,腎結石並非只發生在中老年族群,年輕男性若出現反覆腰痛、血尿或排尿不適,也應提高警覺。
耕莘醫院泌尿外科醫師張建偉指出,尿道結石好發原因多與水分攝取不足有關,夏季是結石好發高峰期,因天氣炎熱、流汗量增加,若未補充足夠水分,尿液容易濃縮,進而增加結晶沉積與結石形成的機會。即使進入秋季,白天仍可能悶熱,民眾若仍有喝水不足、久坐、憋尿或生活作息不規律等情形,仍可能出現相關症狀。

張建偉建議民眾「喝水要喝到尿液清清的」才算足夠,預防結石最重要的方式,就是養成規律喝水習慣,可觀察尿液顏色作為簡單指標,若尿液顏色偏深,通常代表水分攝取可能不足,此外,控制體重、維持均衡飲食,也有助降低結石發生風險。

至於飲食是否需要特別忌口,腎結石種類不同,飲食建議也會有所差異,常需透過結石成分分析後才能更精準判斷。在尚未知道結石種類前,不建議民眾自行過度限制特定食物,原則上應維持均衡飲食,避免單一食物攝取過量或過少,並依醫師建議進一步調整。
張建偉說,腎結石本身可能引發泌尿道感染,若屬於感染性結石,細菌可能藏在結石內;或當結石卡在輸尿管,造成尿液排出受阻時,尿液長時間滯留,便可能導致細菌滋生,嚴重時甚至造成腎臟感染或膿瘍,部分病人接受震波碎石治療後,若結石內含有細菌,碎石過程也可能使細菌釋出,但並非每位病人都需要使用抗生素,仍須由醫師依感染風險與臨床狀況評估。
若出現單側後腰劇烈疼痛、反覆腰痠、血尿、排尿疼痛、發燒或畏寒等症狀,應提高警覺並儘速就醫。平時則應養成充足飲水、避免憋尿、維持正常作息與均衡飲食等習慣,降低結石與泌尿道感染風險。
