itchy
190

192
fecal impaction
- complete colon blockage from hard, immovable stool in rectum
- can produce constipation or overflow incontinence
- community-dwelling older adults at risk
cause: decreased bowel mobility (hospitalized patients and spinal cord injury patients), low-fiber diet
193
older adult changes - male GU system
- no end to fertility, but sperm production decr ≥ 40 years old
- gradual decr in testosterone production ≥ 55 years old
- decr amount of pubic hair & color change to grey/white
- decr in penis and testes size
- decr in tone of dartos muscle = scrotum hanging lower
- decr rugae = pendulous look to scrotum
- decr testosterone = slower and less intense sexual response
- may become demoralized d/t changes in sexual activity
194
Hx (important findings) - male GU
- frequency, urgency, nocturia: polyuria, oligura, infection
- dysuria: acute cystitis, prostatitis, urethritis

- past GU history: incontinence, kidney disease, prostate disease
- penis: infection
- scrotum/testes: hernia, cancer, hydrocele
- sexual activity & contraceptive use: risky sexual activity, STIs, erectile dysfunction
- STI contact: STI
- STI risk reduction: risky sexual activity, no contraceptive use
195
what is polyuria?
urinate more than usual
196
what is oliguria?
urinate less than usual
197
inspection - penis
- penis: wrinkled, hairless, no lesions

- urethral meatus central
hair distribution consistent with age
198
palpation - penis
- compress glans anteroposteriorly between thumb and forefinger
- meatus edge pink, smooth, no discharge
- palpate shaft between thumb and 2 first fingers
- penis smooth, semi-firm, nontender
199
what is hypospadias?
birth defect in boys where the opening of urethra is not located at tip of penis
200
what is epispadias?
birth defect in boys where urethra does not form fully and urethra typically is found in abnormal location
-typically on bottom side of penis
201
inspection & palpation - scrotum
- pt to hold penis out of the way (if unable to, use back of gloved hand)
- size dependent on room temp
- left typically lower than right
- lift scrotal soc for posterior view
- palpate each scrotal half gently
- should slide easily, be freely movable, rubbery, smooth, oval, firm
202
inguinal & femoral hernias
hernia: bulging of internal organs or fatty tissue through on opening in muscle anterior to it
- most common indirect inguinal hernia
- visually see bulge when pt stands
- palpate bump/mass
203
older adult considerations - female GU
- menopause = cessation of menses
- occurs ~48-51 years old
- preceding 1-2 years irregular menses (lighter flow, further apart)
