Total prostate gland volume accurately reflects benign prostatic hyperplasia (BPH) growth. Hyperinsulinaemia is a key factor in BPH development, suggesting a link between insulin levels and prostate enlargement.

Area of Science:

  • Urology
  • Endocrinology
  • Metabolic Syndrome

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition in aging men.
  • The transition zone (TZ) volume is a key indicator of BPH, but total prostate volume is often used as a surrogate.
  • Hyperinsulinaemia, a condition of excess insulin, is suspected to play a role in BPH development.

Purpose of the Study:

  • To validate total prostate gland volume as a measure of transition zone (TZ) volume in BPH.
  • To investigate the causal relationship between hyperinsulinaemia and the development of BPH.

Main Methods:

  • Studied 307 men with lower urinary tract symptoms.
  • Validated total prostate volume against TZ volume in 114 patients using ultrasound.
  • Analyzed BPH risk factors, including metabolic disease, metabolic syndrome components, and fasting plasma insulin levels, in relation to annual BPH growth rate.

Main Results:

  • Total prostate volume strongly correlated with TZ volume (validity coefficient r.s. = 0.97).
  • Faster BPH growth rates were observed in men with metabolic disease, non-insulin-dependent diabetes mellitus (NIDDM), hypertension, obesity, and dyslipidaemia.
  • Higher fasting plasma insulin levels were significantly associated with increased annual BPH growth rate and total prostate volume.

Conclusions:

  • Total prostate gland volume is a valid indicator of BPH.
  • Findings support hyperinsulinaemia as a causal factor in BPH development.
  • Suggests a potential link between hyperinsulinaemia and increased sympathetic nerve activity in BPH.
