nodular hyperplasia of prostate


nod·u·lar hy·per·pla·si·a of pros·tate

glandular and stromal hyperplasia, which is very common in the transition zone and anterior fibromuscular stroma of older men, forming nodules that may increasingly obstruct the urethra.

benign prostatic hyperplasia

Benign enlargement of the prostate, which is normal after age 50 and secondary to androgen and related hormones; BPH pushes against the urethra, blocking urine flow.
 
Clinical findings
Bladder-outlet obstruction, seen in 50% of men ≥ age 60; excess enlargement may obstruct the urethra, causing urinary retention; 30+% require surgery.
