BPH sometimes leads to what anatomical problem?
compression of the urethra and urine flow obstruction
what are the 3 normal prostate tissues
- epithelial - grandular tissue
- stromal - smooth muscle tissue
- capsule
what are the two types of pathophysiology involved with BPH? briefly describe each
- static - androgens cause hyperplasia
2. dynamic - andrenergic tone causes transient effect
what type of pathophysiology is involved in blocking bladdr neck and urinary flow?
static symptoms
what type of pathophysiology includes constriction of urethra and narrowing of lumen
dynamic symptoms
what sympathetic transmitters lead to dynamic symptoms of BPH?
epinephrine and norepinephrine
5-alpha reductase inhibitors deals with what pathophysiology of BPH?
androgens leading to static symptoms
adrenergic receptor blockers deal with what pathophysiology of BPH?
adrenergic tone leading to dynamic symptoms
