研究术区引流液肌酐监测在诊断腹盆腔手术后尿路损伤及尿漏的作用。

回顾分析2015年1月至2021年6月在珠海市人民医院行腹盆腔术后尿路损伤及尿漏的33例患者资料，同时倾向性匹配该院同时期腹盆腔手术后无尿路损伤或尿漏的33例患者。比较两组患者引流液肌酐、引流液/血液肌酐比值的差异。

两组血肌酐差异无统计学意义，尿路损伤组的引流液肌酐2 754（2 133）μmol/L、引流液/血液肌酐比值133（57）均远远高于无尿路损伤组101（61）μmol/L，0.99（0.32），（P均<0.001）。

腹盆腔手术后监测引流液肌酐、引流液/血液肌酐比值对术后尿路损伤的诊断十分准确，是一个便捷、有效的诊断方法。

To investigate the role of creatinine monitoring in the diagnosis of urinary tract injury and urinary leakage after complicated abdominal pelvic surgery.

The data of 33 patients with urinary tract injury and urinary leakage after abdominal and pelvic surgery in Zhuhai People's Hospital from January 2015 to June 2021 were retrospectively reviewed, and 33 patients without urinary tract injury after abdominal and pelvic surgery in the hospital during the same period were matched. The creatinine of drainage fluid and the ratio of drainage to blood creatinine were compared between the 2 groups.

There was no difference of blood creatinine between the two groups. The creatinine of drainage fluid 2 754(2 133) μmol/L and drainage fluid/blood 33(57) in the urinary tract injury group were significantly higher than those in the non-urinary tract injury group 101(61) μmol/L, 0.99(0.32) (P<0.001).

Monitoring the creatinine of drainage fluid and drainage fluid/blood creatinine ratio after abdominal pelvic surgery is very accurate for the diagnosis of postoperative urinary tract injury, which is a convenient and effective diagnostic method.
