The Predictive Value of Non-Invasive Urodynamic Parameters for the Curative Effect of TURP

Abstract

Purpose: To explore the predictive value of non-invasive urodynamic parameters for the efficacy of transurethral resection of the prostate (TURP). Methods: 121 cases, Benign prostatic hyperplasia (BPH) patients were assessed retrospectively and were divided into good prognosis (group A) and poor prognosis (group B) according to the degree of improvement in maximum urinary flow rate, and the changes in ultrasound and non-invasive urodynamic parameters between the two groups were explored. Results: The PV, IPP, and PVR of group A were lower than those of group B (P＜0.05), and Qmax of group A was greater than group B (P＜0.05). The difference was statistically significant (P＜0.05); There was no significant difference in DWT, age, and IPSS(P＞0.05). The ROC curve analyzes the diagnostic efficacy of each parameter in the diagnosis of the efficacy of TURP, and the results are ranked in order of 1/Qmax (AUC=0.777), PV (AUC=0.715), PVR (AUC=0.642), IPP (AUC=0.629), Of which 1/Qmax has the best diagnostic efficiency, and it AUC=0.777, the best cutoff value is 0.12, the sensitivity is 0.81, and the specificity is 0.571. Conclusion: Preoperative application of non-invasive urodynamic parameters in BPH patients can better predict postoperative efficacy, especially Qmax has the best predictive effect.
