Clinical features of acute urine retention in patients with benign prostate hyperplasia / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To explore the clinical features of acute urine retention (AUR) ocurring in patients with benign prostate hyperplasia (BPH).@*METHODS@#Clinical data from 548 patients diagnosed with BPH were retrospectively studied, and the clinical parameters of these patients with or without AUR were analyzed by statistical methods.@*RESULTS@#Development of AUR was found in 164 patients (29.9%). Patients' age, IPSS, maximum flow rate (Q(max)), residual urine volume, prostate volume, transition zone volume, prostate-specific antigen (PSA) density, total PSA (tPSA) and free PSA (fPSA) including the ratio of free to total PSA(f/tPSA) were significantly different in the 2 groups (P0.05). Multivariate logistic regression analysis showed that IPSS score, residual urine volume, tPSA, and Q(max) were risk factors for predicting the development of AUR.@*CONCLUSION@#BPH patient's age, IPSS, Q(max), residual urine volume, prostate volume, transition zone volume, tPSA and fPSA, and PSA density all influence the occurrence of AUR, in which symptom severity, residual urine volume, total PSA and Q(max) are the principal risk factors for prognosing AUR.
