The Predictive Value of Prostate Spherical Volume Ratio in Lower Urinary Tract Symptoms and Clinical Progression of Benign Prostatic Hyperplasia:A Single-center Paired Validating Confirmatory Study

This was a retrospective observational study approved by the Ethics Committee of Shanghai Oriental Hospital. We collected patients with BPH who underwent MRI, urine flow measurement and completed the IPSS questionnaire in our hospital between September 2022 and April 2023, measured each anatomical parameter of the patient's prostate by MRI, analysed the relationship of these prostate parameters with IPSS and urine flow, and conducted a follow-up of the clinical progression of the prostate in these patients to evaluate the predictive efficacy of prostate parameters for LUTS and clinical progression of benign prostatic hyperplasia.

Inclusion criteria

• All patients had obvious lower urinary tract symptoms such as urinary frequency, increased nocturia, and a feeling of incomplete urination, etc. They all completed prostate MRI, IPSS questionnaire, and uroflowmetry for a clear diagnosis of BPH.

Exclusion criteria

• 1, previous history of bladder, prostate, urethra surgery; 2, the existence of other diseases that cause urinary dysfunction: such as neurogenic bladder, bladder stones, urethral stenosis, urinary tract infections, acute prostatitis, etc.; 3, the existence of mental, mental disorders, can not be accurately expressed and family members can not help to improve the IPSS scores; 4, to receive prostatic hyperplasia medication, such as: α-blocker therapy, 5α reductase inhibitors, etc. have not been discontinued for 6 months; 5, refused to participate in this study
