Predicting BPH Surgery Outcomes Using a Preoperative Scoring System
Development and Clinical Application Value of a Predictive Scoring System for Postoperative Outcomes Following Transurethral Resection of the Prostate Based on Preoperative Multidimensional Objective Indicators
This study aims to develop and validate a preoperative predictive scoring system for surgical outcomes in patients with benign prostatic hyperplasia (BPH) undergoing prostate surgery (including but not limited to transurethral resection of the prostate, laser enucleation, photoselective vaporization, or robot-assisted simple prostatectomy).
It is a multicenter retrospective study involving patients from four hospitals in China. Preoperative multidimensional objective indicators, including clinical data, prostate MRI parameters, and urodynamic measurements, will be collected. The primary outcome is a favorable surgical response defined by a postoperative-to-preoperative International Prostate Symptom Score (IPSS) ratio ≤ 0.5 at 6 months after surgery.
Multivariable logistic regression, restricted cubic splines, and bootstrap internal validation will be used to construct and evaluate the scoring system. The goal is to provide an objective, individualized tool for optimizing surgical decision-making in BPH patients.

BPH Patients Undergoing Prostate Surgery
Patients with BPH who underwent prostate surgery (various techniques including TURP, laser enucleation, PVP, or RASP) between Jan 2020 and Aug 2025 across four centers.
Preoperative MRI and urodynamic data collected.
Primary outcome: IPSS ratio ≤0.5 at 6 months post-surgery.

Proportion of patients with favorable surgical response at 6 months post-surgery
Tidsram: 6 months after surgery
|
Favorable surgical response is defined as a ratio of postoperative International Prostate Symptom Score (IPSS) to preoperative IPSS ≤ 0.5 at 6 months after surgery.
IPSS assesses lower urinary tract symptoms, with scores ranging from 0 to 35 (higher scores indicating more severe symptoms).
A ratio ≤ 0.5 represents at least 50% improvement from baseline.
