Construction of an individual nomogram model for predicting the risk of stress urinary incontinence after transurethral enucleation of the prostate
Objective To investigate the influencing factors of stress urinary incontinence(SUI)after transurethral enucleation of the prostate(TUEP),and to construct an individual nomogram model to predict the occurrence of SUI.Methods A total of 557 patients with benign prostatic hyperplasia(BPH)who underwent TUEP in Cangzhou People's Hospital from March 2019 to June 2022 were selected as study objects,and were followed up for 6 months after operation.The patients were grouped into SUI group and non-SUI group according to whether SUI occurred or not.The differences in the collected data between the two groups were analyzed,and the factors with statistical significance were included in the Logistic regression analysis.Finally,the factors affecting the occurrence of SUI after TUEP were screened out,and the nomogram model was constructed using RMS package in R software.The area under the curve(AUC)of receiver operating characteristic(ROC)was applied to evaluate the prediction effect of the model,and the H-L goodness of fit test was performed.Results SUI occurred in 51(9.16％)of 557 BPH patients after TUEP.There were statistically significant differences in proportion of patients aged ≥75 years,proportion of patients with diabetes,prostate volume,duration of operation,weight of enucleated tissue during operation in SUI group compared with non-SUI group(P＜0.05).Logistic regression analysis showed that the risk factors for SUI in BPH patients after TUEP included age ≥ 75 years,suffered from diabetes,large prostate volume,and long operation duration(P＜0.05).Four factors were introduced into R software to construct the nomogram model,and the results showed that AUC was 0.834(95％CI:0.756-0.912),and the goodness of fit H-L test x2=7.108,P=0.527.Conclusions The nomogram model constructed with age ≥ 75 years,suffered from diabetes,large prostate volume and long operation duration can well predict the risk of SUI occurence after TUEP.
