A 65-year-old man visits his physician because of increasingly difficult urination. He has trouble initiating a stream and experiences postvoid dribbling. He wakes from sleep three times per night to urinate. His baseline creatinine level was 1.0 mg/dL, and it is now 1.5 mg/dL. Which treatment is most feasible to immediately improve this patient’s creatinine level?
一名65岁的男性因排尿困难而拜访了他的医生。他很难开始排尿,并且会出现残余尿液。他每晚要起床三次去上厕所。他基础肌酐水平为1.0 mg/dL,现在是1.5 mg/dL。哪种治疗方法最可行,可以立即改善这位患者的肌酐水平?
(A) Administration of fluid boluses 输液 (B) 透析
(B) Dialysis 透析
(C) Placement of a Foley catheter 导尿
(D) Prostatectomy 前列腺切除术
答案解析:
该患者的症状符合良性前列腺增生 (BPH),包括排尿困难、排尿后滴尿和夜间尿频。 在这种情况下,包裹前列腺尿道的大前列腺引起尿路梗阻,导致肾功能下降,表现为肌酐水平升高。 在超声波上,您可能能够看到尿液收集系统的扩张。 放置良好的 Foley 导管可彻底缓解阻塞。
正确答案:C
