Early Electroacupuncture for Post-TURP LUTS

Sponsor: Zhongda Hospital

Summary

1\. Project Rationale Benign prostatic hyperplasia (BPH) is one of the most prevalent urological disorders among middle-aged and elderly men, and it represents a common chronic condition in the male population. Its incidence increases from 8% in men aged 31-40 years to over 80% in men aged over 80 years. With the intensification of global population aging, the prevalence of BPH and the corresponding burden on global public healthcare systems have been increasing continuously. BPH not only impairs patients' micturition function and reduces their quality of life, but also may lead to multiple complications involving the urinary system, such as urinary tract infection, bladder calculi and renal function impairment. Although the exact etiology of BPH remains incompletely elucidated, existing studies have confirmed that multiple factors including age, altered hormone levels, genetic background and lifestyle are associated with its pathogenesis. The global number of prevalent BPH cases increased from 51 million in 2000 to 94 million in 2019, representing a 70.5% growth in global prevalence during this period. Driven by population aging, changes in lifestyle and the popularization of screening methods such as prostate-specific antigen (PSA) detection, the number of prevalent BPH cases in China increased from 10.2 million in 2000 to 20.3 million in 2019, with a 99.0% growth in prevalence over the period, which exceeds the global average growth rate. Data from the 7th National Population Census of China in 2021 shows that the population aged 60 years and above in China reaches approximately 264 million, accounting for 18.70% of the total population, which is 5.44 percentage points higher than the data from the 6th National Population Census in 2010, and this figure is projected to exceed 400 million by 2050. The intensification of population aging and the corresponding growth in BPH prevalence indicate that BPH has evolved from a common urological disease to a major public health issue that poses a substantial threat to the health of Chinese men. Transurethral resection of the prostate (TURP) and holmium laser enucleation of the prostate (HoLEP) are routine surgical interventions for BPH, which can effectively reduce prostate volume and improve micturition function in patients. However, persistent lower urinary tract symptoms (LUTS) such as urinary frequency, urgency and dysuria after surgery still negatively affect patients' quality of life. Approximately 30% of patients with pre-operative urological symptoms experience persistent symptoms after surgery. Due to symptom persistence, up to 27% of male patients receive pharmacological intervention for LUTS after TURP. This poses a great challenge to patients' physical and mental health, and effective intervention strategies are urgently needed. Currently, the management of post-TURP LUTS mainly relies on conservative interventions such as Pelvic Floor Muscle Training (PFMT) and pharmacological therapy. However, these interventions are typically initiated after urinary catheter removal, which cannot meet the demand for immediate urinary continence after catheter withdrawal. In addition, the therapeutic effect of PFMT requires long-term persistence, which generally leads to poor patient adherence, and the most critical limitation is the lagged intervention timing. Similar issues including delayed intervention and unsatisfactory efficacy also exist in pharmacological therapy. Currently, medications for LUTS secondary to BPH include α-adrenergic receptor blockers, 5-α reductase inhibitors, anticholinergics, β-3 adrenergic receptor agonists and phytotherapy. These agents are routinely used for the management of BPH and BPH-related LUTS, and are widely applied to alleviate persistent or new-onset LUTS after BPH surgery. Although these drugs are generally adopted as standard interventions for post-BPH surgery LUTS, multiple studies have demonstrated that there are no significant differences in objective indicators including symptom score, quality of life index and post-void residual volume between patients receiving these medications after BPH surgery and patients receiving placebo. Currently, there is still a lack of effective and widely accepted intervention regimens for LUTS after BPH surgery. Against the background that existing treatment modalities cannot meet clinical demand, this study proposes early post-operative electroacupuncture as an innovative and scientifically sound intervention strategy. Acupuncture is not merely a simple "alternative therapy", but an effective "non-invasive peripheral neuromodulation technique" validated by modern medical research. Existing studies have shown that acupuncture exerts a certain therapeutic effect on relieving BPH-related LUTS. For example, in a study conducted by Chen Chao et al., clear conclusions were drawn by comparing the efficacy of acupuncture and α-adrenergic receptor blockers in the treatment of 64 patients with BP
