Q

LUTS in men and treatment

A

BPH - hyperplasia of the cells in the stromal/glandular cells of the prostate.
It causes voiding symptoms and can cause obstruction symptoms after a while.
To diagnoise - do IPSS to see the effects on life, and a PSA.
Then if its more than 8 you start with an alpha blocker, with blocks alpha cells on smooth muscle cells of prostate allowing relaxation and ability to urinate - tamsulosin - review 4-6 weeks, modified ipss and then 6-12 months.
If this does not work and have obstruction symptoms - include finesteride - 5areductase inhibitor- so you dont mind dehidrotesterone - which causes hyperplasia.
If you have urinary incontience - stress incontinence, offer pads and pelvic floor training
Over active bladder - bladder training and oxybutocin
if its nocturia - offer furesomide (make sure it isnt to do with ms or diabetes or parkinsons)
if urinary retention then ovver - An alpha-blocker (modified-release alfuzosin 10 mg a day) and cathertisation may be needed
chronic then intermitten catherisaion and management infrequently

All patients - diet, exercise, body weight, alcohol, smoking, less fizzy drinks/sweeteners and caffeine.
