目的了解近年肾移植后尿路感染的情况。方法分析我院420例肾移植后尿路感染的有关资料。结果7．4％发生尿路感染，其中67．8％发生在移植后1个月内。有发热者仅19．4％，有尿路刺激征者为12．9％，白细胞尿61．3％，合并败血症9．7％。病原菌以肠道菌属为主，但绿脓杆菌、混合感染、真菌感染的比例升高，共达29％。增加免疫抑制剂用量或使用抗淋巴细胞球蛋白/抗腺细胞球蛋白（ALG／ATG）或OKT3的患者更易发生尿路感染。结论肾移植后尿路感染值得临床医生重视。
Objective To understand the urinary tract infection after renal transplantation in recent years. Methods To analyze the data of 420 cases of urinary tract infection after renal transplantation in our hospital. Results Urinary tract infection occurred in 7.4%, of which 67.8% occurred within 1 month after transplantation. Only 19.4% of those with fever, urinary tract irritation was 12.9%, leukocytosis 61.3%, with sepsis 9.7%. The main pathogens to intestinal bacteria, but Pseudomonas aeruginosa, mixed infections, the proportion of fungal infections increased, up to 29%. Urinary tract infections are more likely to occur in patients who increase their use of immunosuppressants or use anti-lymphocyte globulin / anti-gland globulin (ALG / ATG) or OKT3. Conclusion Urinary tract infection after renal transplantation deserves clinicians’ attention.
