Benign prostatic hypertrophy resulting in urinary obstruction arises form which lobe of prostate gland?
Ans. is 'c' i.e., Median Anatomical division of Prostate*Prostate has 5 lobes :*Anterior lobe# Is a small isthmus connecting the two lateral lobes in front of the urethra.*Posterior lobe# It connect the two lateral lobes behind the urethra. It lies behind the median lobe and the ejaculatory ducts. Carcinomas are most common in this lobe.*Median lobe# Lies behind the upper part of the urethra, in front of the ejaculatory ducts just below the neck of the bladder.# Benign Hyperplasia of Prostate arises in this lobe.*Lateral lobes# Lie one on each side of the urethra.Zonal or surgical division of Prostate*Prostate has 3 distinct zonesa) The peripheral zone (PZ) - accounts for 70% of volume of young adult prostateb) The Central zone (CZ) - accounts for 25%c) The transition zone (TZ) - accounts for 5%*Carcinoma of prostate arises most commonly in - the peripheral zone*Benign prostatic hyperplasia originates in - the transition zone
