Analysis Of Risk Factors Of Stress Urinary Incontinence After Transurethral Enucleation And Resection Of Prostate

Background and objective:Benign Prostatic Hyperplasia(BPH)is one of the most common diseases in the clinical work of urology in the world,which is also a common disease causing chronic urinary dysfunction in middle-aged and elderly men.In recent years,Transurethral Enucleation and Resection of Prostate(TUERP)is becoming the preferred method for more surgeons to treat BPH.Compared with Transurethral Resection of Prostate(TURP),TUERP has less blood loss,shorter catheterization duration,and fewer postoperative hospitalization days.However,TUERP has a certain risk of postoperative Stress Urinary Incontinence(SUI),which can greatly affect patients’quality of life.Therefore,this study aims to retrospectively analyze and summarize the risk factors of postoperative SUI in BPH patients undergoing TUERP by collecting and analyzing perioperative related indicators.Methods:Data of 259 patients with BPH who received TUERP due to BPH from Zhujiang Hospital of Southern Medical University in January 2020 to December 2020 were retrospectively analyzed.Patients with postoperative SUI and those without SUI were divided into two groups,univariate and multivariates logistic regression analysis were conducted for influencing factors that might affect the occurrence of SUI after TUERP.Results:According to inclusion and exclusion criteria,193 patients were included in the study,including 143 patients without SUI and 50 patients with SUI,with an incidence of 25.9%;30 patients still had SUI after 1 month,with an incidence of 15.5%.;16 patients with SUI after 3 months,with an incidence of 8.3%.;12 patients with SUI after 6 months,with an incidence of 6.2%;2 patients with SUI after 12 months,with an incidence of 1.1%.The results of univariate analysis showed that body mass index(Body Mass Index,BMI)≥28,prostate volume≥70ml,history of diabetes,and alcohol consumption were statistically significant for the occurrence of SUI after TUERP(P<0.05),while age,hypertension history,smoking history and tPSA were no significant differences between the two groups(P>0.05).Multivariate analysis showed that BMI≥28,prostate volume≥70ml and diabetes mellitus history were independent risk factors for SUI after TUERP(P<0.05),while alcohol consumption history was a protective factor for SUI after TUERP(OR=0.334).Based on the results obtained,a model was established to predict the risk of SUI after TUERP,and the model was verified to be accurate.Conclusions:TUERP can significantly improve urinary symptoms in BPH patients.Compared with Transurethral Resection of Prostate(TURP),TUERP has less blood loss,shorter catheterization duration,and fewer postoperative hospitalization days.However,there are disadvantages of postoperative SUI,among which diabetes mellitus history,large prostate volume,and obesity are risk factors for SUI in BPH patients after TUERP,while alcohol consumption history was a protective factor for SUI after TUERP.The established model has the function of predicting the risk of SUI after TUERP.
