3 Genitourinary Flashcards
blood urea nitrogen (“normal”)
5 - 25 mg/dl
creatinine (“normal”)
0.5 - 1.5 mg/dl
phimosis
narrowing or stenosis of the opening of the foreskin that prevents retraction of the foreskin
paraphimosis
retracted foreskin that cannot be replaced in normal position over glans
paraphimosis significance?
urological emergency!!!
hydrocele: non-communicating
often subsides spontaneously
surgery if not spontaneously resolved at one year
hydrocele: communicating
requires surgery if not spontaneously resolved at one year
- scrotum smaller in the morning, larger after activity
hydrocele
presents as soft, painless swelling of scrotum (palpable bulge in inguinal/scrotal area)
- asymptomatic
acute scrotum
acute PAINFUL swollen scrotum in prepubertal child
urgent/emergent finding!!!
- requires immediate diagnosis and possibly surgery
- treatment delay may result in loss of testicle
cryptorchidism
undescended testicles (one or both)
- not painful
- doesn’t interrupt urination
- scrotum appears underdeveloped on affected side
- WATCH AND SEE WHAT HAPPENS
orchiopexy
surgical treatment for cryptorchidism - happens at 1 to 2 years of age
why orchiopexy?
- prevents teste overexposure to body heat (protect fertility)
- decrease incidence of malignancy (high in undescended testes)
- avoid rigorous activity for 2 weeks (education needed!)
AMS significant…
in geriatric populations with UTI. Usually no other symptoms.
blood urea nitrogen (BUN)
normal range: 5-25 mg/dl
- by-product of protein breakdown in liver. Urea nitrogen is produced mostly from liver metabolism of food
- other factors influential. elevation does not always mean kidney disease present
- elevated BUN level is highly suggestive of kidney dysfunction
creatinine
normal range: 0.5 - 1.5 mg/dl
- produced with muscle/protein breaks down
- constant so good measure of kidney function
- No common pathologic condition other than kidney disease increases the serum creatinine level
- does not increase until at least 50% of kidney function lost
BUN vs creatinine
creatinine is more specific reflection of kidney function and renal disease
waste products in blood reflective of kidney function
BUN
creatinine
severe phimosis treatment
circumcision
hypospadias
urethral opening below glans penis (anywhere along ventral surface)
mild hypospadias
meatus just below tip of penis
severe hypospadias
meatus on perineum (+ chordee)
chordee
ventral curvature of penis accompanying severe hypospadias
- hypospadias care key point
thorough assessment important - must inform parents that circumcision cannot happen because foreskin may be used in repair of penis
don’t want to take newborn into surgery - need to allow baby to feed and grow and THEN do surgery (better outcome)
epispadias
defect on dorsal surface of penis
bladder extrophy
severe defect with externalization of bladder (males and females)
repair in newborns a MUST
bladder extrophy in males…
is almost always seen with epispadias
bladder extrophy/epispadias correction…
may require multiple stages of repair depending on severity of defect
- first stage: repair bladder
- second stage: repair epispadias and create urethral sphincter
GFR + “normal”
glomerular filtration rate - 115 to 125 ml/min
controlled by dilation/constriction of afferent arterioles
decreased GFR with aging
- decreased ability to regulate water balance
- GFR drops about 10% for adults 45+
- a concern with chronic comorbidities like DM2, htn, CHF; which further decrease blood flow to kidneys
problems related to decreased GFR
- dehydration
- increased renal blood flow
- increase in nephrotoxic potential of many meds
nocturia
tubular changes lead to decreased ability to concentrate urine resulting in sense of urgency + nocturia
nocturia nursing implications
- encourage nighttime lighting and clutter free environment
- encourage fall risk clients to use bedpan, urinal, bedside commode
- discourage fluid intake 2-4 hours prior to bedtime
decreases in bladder capacity and spincter tone due to…
(aging)
- changes in detrusor muscle elasticity = decreased capacity
- sphincters lose tone and become weak
urinary retention causes (x3)
(men) enlarged prostate = narrowing of the prostatic urethra = hesitancy, decreased force of stream, urinary retention
(anticholinergic medications)
(diseases affecting CNS = neurogenic bladder)
urinary retention nursing implications
- assess for bladder distension
- monitor for s/s of UTI
- provide stimuli to encourage urination
UTI s/s
- dysuria
- confusion
- foul smelling urine
top 7 contributing factors of chronic disease
- hypertension
- tobacco use
- elevated cholesterol
- poor dietary choices
- obesity
- physical inactivity
polycystic kidney disease - acquired how?
genetically
polycystic kidney disease characteristics
- multiple cysts in nephrons
- compromised function
- larger than average kidneys
- hypertension
polycystic kidney disease risks
- cyst rupture
- bleeding
- infection
polycystic kidney disease most common complication
chronic UTI
- polycystic kidney disease most SERIOUS complication
end stage renal disease
polycystic kidney disease s/s
- PAIN ** abdominal or flank. almost always first sign.
- distended abdomen, increased abdominal girth
- BLOODY ** or cloudy urine
- constipation
- nocturia
- hypertension
- kidney stones
vesicoureteral reflux
the backward flow of urine from the bladder into the kidneys
