Analysis of influencing factors of postoperative blood loss in patients un-dergoing transurethral plasma kinetic prostatectomy of the prostate and construction of a nomogram prediction model
摘要
Abstract
Objective To investigate the influencing factors of postoperative blood loss after transurethral plasma kinetic prostatectomy of prostate and establish a prediction model and verify it.Methods A total of 180 patients with benign prostatic hyperplasia who received transurethral plasma kinetic prostatectomy of the prostate in the First People's Hospital of Fuzhou City from January 2022 to October 2024 were selected as the study objects.According to the postoperative blood loss,they were divided into observation group(blood content of flushing solution＞30 mg/h,n=58)and control group(blood content of flushing solution≤30 mg/h,n=122).The clinical data of the two groups were collected,and the risk factors of blood loss after transurethral plasma kinetic prostatectomy of prostate were analyzed.Univariate analysis and multivariate logistic regression analysis were carried out,and the nomogram prediction model was constructed with R language software for venification.Results The results of the univariate analysis showed that the operative time,diabetes mellitus,preoperative use of antiplatelet drugs,intraoperative injury to the capsule,incomplete intraoperative hemostasis,postoperative bladder spasm were related to a large amount of postoperative bleeding,and the differences were statistically significant(P＜0.05).Multivariate logistic regression model analysis showed that operation time(β=0.145,OR=1.156,95％CI:1.095-1.22),preoperative use of antiplatelet drugs([3=2.022,OR=7.557,95％CI:2.837-20.132),intraoperative injury to the capsule(β=1.016,OR=2.761,95％CI:1.098-6.943),postoperative bladder spasm(β=1.388,OR=4.006,95％CI:1.595-10.063)were independent risk factors for postoperative blood loss(P＜0.05).The CI of risk predicted by the nomogram model was 0.894(0.831-0.957).The risk threshold of large postoperative blood loss predicted by simulation was＞0.17.Conclusion The purpose of this study is to comprehensively investigate the influencing factors of blood loss after transurethral plasma kinetic prostatectomy of the prostate,to build a nomogram prediction model,to provide a powerful tool for accurately predict-ing the risk of postoperative,to better guide clinical practice and improve patient prognosis.Clinically,the above-mentioned risk factors should be noted.关键词
