encourage fluid intake unless contra
reduce discomfort like sitz baths
analgesics and antispasmodics
assess voiding and hygiene
191
pyridium
antispasmodic
turns urine orange/red
very potent
same as uristat but higher concentration
192
postop management of kidney surgery
Potential hemorrhage and shock
Widening pulse pressure
HR increases then decreases
Pallor
Nausea
potential abd distention from bleeding and paralytic ileus (use blakemore sengsten tube [black and weighted])

med management of kidney stones
allow stone to pass
pain management
hot bath or moist heat to flank
ten 8oz glasses of water a day
urine output 2L/day
strain urine
NO OPIOIDS, use toridol (antiinflammatory)
200
gerontologic consideration for kidney stones (temperature)
normal looking temperature like 99 is bad
normally they’re a bit colder like 97 so 99 can be sepsis

Birth defects, trauma, strictures, neurogenic bladder, chronic infection or intractable cystitis
Used as a last resort for incontinence
208
types of urinary diversion

209
pt teaching of urinary ostomy
changing appliance, controlling odor, managing the ostomy appliance, cleaning and deodorizing the appliance, continuous care
210
BPH manifestations
those of urinary obstruction, urinary retention, and urinary tract infections (due to urinary stasis)
211
treatment of BPH and SE
alpha-adrenergic blockers, alpha- adrenergic antagonists, antiandrogen agents (-zosins)
Finasteride
Catheterization if unable to void
Prostate surgery
antiadrogen causes gynecomastia and facial feminization
212
risk factors of BPH
Estrogen and testosterone play a role
smoking, Etoh, obesity, sedentary lifestyle, HTN, CVD, DM, Western diet; increase fat, animal protein, refined carb
213
S&S of BPH
Frequency, urgency, nocturia, hesitancy, decreased force of stream, incomplete void, straining, dribbling, urinary retention, recurrent UTI
fatigue, anorexia, nausea, vomiting, pelvic discomfort
214
diagnosis of BPH
voiding diary
health/family hx
DRE: large, rubbery, non-tender, gloved hand goes in to feel for prostate
PSA: prostatic specific antigen
American urological association scoring to help grade severity of symptoms
UA, culture
Ultrasound
215
management of BPH
Meds: alpha-adrenergic blockers alfuzosin, terazosin
5-alpha-reductase inhibitor finasteride
saw palmetto (can mask serious problem) little data to support but often taken by pt.
Minimally invasive: transurethral microwave heat treatment (TUMT) transurethral needle ablation (TUNA)
216
surgery for BPH
Transurethral resection of prostate (TURP)
watch catheter
lots of bleeding, should look pinkish but not red red
if clots r there, should be small enough to pass
217
three way system for bladder irrigation
irrigating bladder wall, VERY vascular so try to minimize bleeding
218
risk factors of prostate cancer
increasing age, familial predisposition, and African-American race
219
manifestations of prostate cx

use meds and warm compresses/sitz baths
analgesics
walk dont sit!
prevent constipation
irrigate catheter
226
pt teaching after prostate surgery
Sometimes clamp off bladder so urine builds up, helps them regain sensation
Information that regaining control is a gradual process (dribbling may continue for up to 1 year depending upon type of surgery)
perineal exercises
avoid straining, heavy lifting, and long car rides for 6-8w
fluids! no coffee, alcohol or spice
urologist for sex questions
