OBJECTIVE: To explore the risk factors for long-term hematuria after operation in BPH patients. METHODS: We retrospectively analyzed the clinical data on 646 cases of BPH treated by transurethral surgery in Liyang People's Hospital from January 2015 to August 2020. According to the incidence of hematuria at 3 months or longer after surgery, we divided the patients into a hematuria and a non-hematuria group, recorded the related factors, and investigated the independent risk factors for long-term hematuria by univariate and multivariate analyses. RESULTS: Of the 646 BPH patients, 48 were found with and 598 without hematuria after transurethral surgery. Univariate analysis showed that hypertension, diabetes mellitus, residual prostate gland, urinary tract infection, bladder neck contracture, prostate cancer, urethral calculus, urethral stricture, excessive activity and constipation were the influencing factors (P < 0.05), while multivariate logistic regression analysis revealed that hypertension (P < 0.001), diabetes mellitus (P = 0.007), residual prostate gland (P = 0.013), urinary tract infection (P < 0.001), bladder neck contracture (P = 0.032), urethral calculus (P = 0.033) and urethral stricture (P = 0.001) were independent risk factors for long-term hematuria in the BPH patients after surgery. CONCLUSION: Complicated hypertension, diabetes mellitus, residual prostate gland, urinary tract infection, bladder neck contracture, urethral calculus and urethral stricture are independent risk factors for long-term hematuria in BPH patients after transurethral surgery.
