目的 觀察左氧氟沙星膠囊聯(lián)合癃清片治療2型糖尿病合并尿路感染的療效和安全性。方法 選取平邑縣人民醫(yī)院2012年10月—2013年10月住院的2型糖尿病合并尿路感染患者209例，將其隨機分為治療組（105例）和對照組（104例），所有患者根據(jù)病情分別選用口服降糖藥和（或）胰島素控制血糖，并根據(jù)血糖情況調整降糖方案，使血糖控制理想。對照組患者口服鹽酸左氧氟沙星膠囊，2粒/次，2次/d；治療組在對照組基礎上口服癃清片，6片/次，2次/d，兩組均治療7 d。觀察治療前后患者的臨床癥狀、尿常規(guī)變化和不良反應。結果 治療組和對照組有效率分別為95.2%、76.9%，兩組比較差異有統(tǒng)計學意義（P＜0.05）；治療后，患者尿常規(guī)中白細胞和紅細胞計數(shù)均顯著減少，治療組減少更加明顯，差異具有統(tǒng)計學意義（P＜0.05）。胃部不適為最常見的不良反應，兩組間差異無統(tǒng)計學意義。結論 左氧氟沙星膠囊聯(lián)合癃清片治療2型糖尿病合并尿路感染有很好的療效，治療過程中的不良反應較少，值得臨床應用。
