GU (Exam 3) Flashcards
Urinary incontinence
loss of urinary control
Enuresis
involuntary urination by a child after 4-5 years of age
causes may be psychological and structural, but usually resolves with or without treatment
Nocturnal Enuresis
bed wetting
Stress Incontinence
loss of urine from pressure exerted on the bladder by coughing, sneezing, laughing, exercising or lifting something heavy
occurs when sphincter muscle of the bladder is weakened
pregnancy, childbirth, menopause, cystocele, prostate removal, obesity, chronic coughing are contributing factors
Overactive bladder (Urge Incontinence)
sudden, intense urge to urinate followed by an involuntary loss of urine
CAUSES: UTIs, bladder irritants, bowel conditions, smoking, Parkinson’s disease, Alzheimer’s disease, stroke, injury, nervous system damage
Reflex Incontinence
urinary incontinence caused by trauma or damage to nervous system; urgency is generally absent
detrusor hyperreflexia
Detrusor hyperreflexia
increased detrusor muscle contractility that occurs even though there is no sensation to void
Mixed Incontinence
occurs when symptoms of more than one type of urinary incontinence is experienced
Overflow Incontinence
inability to empty the bladder or retention; dribbling urine and a weak urine stream
CAUSES: bladder damage, urethral blockage, nerve damage, prostate conditions
chronic overdistention occurs because of a perceived inability to interrupt work to void that results in detrusor muscle areflexia and overflow incontinence
Functional Incontinence
occurs in many older adults who have a physical or mental impairment that prevents toileting in time
Transient Incontinence
urinary incontinence resulting from a temporary condition
CAUSES: delirium, infection, atrophic vaginitis, certain meds (diuretics, sedatives), psychological factors, high urine output, restricted mobility, fecal impaction, alcohol, caffeine
Gross Total Incontinence
a continuous leaking of urine, day and night, or the periodic uncontrollable leaking of large volumes of urine; the bladder has no storage capacity!!
CAUSES: anatomic defects, spinal cord/urinary system injury, fistulas between bladder and adjacent structure like vagina
Risk Factors for Incontinence
female
advancing age
overweight
smoking
renal disease
Complications for Incontinence
skin breakdown
recurrent UTIs
negative psychological consequences
interruption of usual activities

dementia
Parkinson’s
spina bifida
diabetes mellitus
stroke
meds
vaginal childbirth
MS

Interstitial Cystitis/Bladder Pain Syndrome
chronic bladder condition more common in women and aging people that causes pain and pressure in suprapubic, pelvic, and abdominal area
EXACT CAUSE UNKNOWN!!
5% experience symptoms for 2+ yrs and below 5% develop end stage disease where bladder hardens, capacity is low and pain worsens
Interstitial Cystitis/Bladder Pain Syndrome Manifestations
pain in urinary tract (often worse with pressure)
frequency and nocturia
urgency (often constant worsened by stress)
sexual dysfunction
Urinary Tract Infection (UTIs)
among the most common bacterial infections encountered in clinical practice, most commonly an ascending infection
Risk Factors for UTIs
female genitalia
sexually active (multiple partners increases risk)
use of diaphragm with spermicide
history of diabetes
recent instrumentation (catheters)
structural abnormalities
improper personal hygiene
immobility
Upper UTIS
pyelonephritis (acute and chronic)
Lower UTIs
cystitis and urethritis
Cystitis
infections in the bladder where the bladder and urethra walls become red and swollen; bacteria ascend to the bladder via urethra and possibly further up to kidneys (E. Coli 75-95%)
CAUSES: infection and irritants
Lower UTI Symptoms
burning on urination
urgency
dysuria
frequency
low back pain
foul smelling urine
cloudy urine (pyuria)
hematuria
fever (occasionally)
Sx MAY DIFFER WITH AGE AND URINARY TRACT FUNCTION; ELDERLY = CONFUSION
Upper UTI Symptoms (up to kidneys)
flank pain
fever
nausea
vomiting
increased BP
may have symptoms of cystitis
Sx MAY DIFFER WITH AGE AND URINARY TRACT FUNCTION; ELDERLY = CONFUSION
Pyelonephritis
acute/chronic infection that has reached one or both kidneys
kidneys become edematous and fill with exudate, compressing renal artery and potentially developing abscesses or necrosis
Pyelonephritis Complications and Manifestations
C: renal failure, recurrent UTIs, sepsis
M: severe UTI symptoms, flank pain, increased BP
Renal and Urinary Calculi
hard crystals composed of minerals that kidneys normally excrete in renal pelvis, ureters or bladder; more common in men and whites
MOST FREQUENT TYPE CONTAIN CA WITH EITHER OXALATE OR PHOSPHATE
other types are struvite/infection stones, uric acid stones, cystine stones
Risk Factors of Renal Calculi
pH changes
excessive concentration of insoluble salts in urine
urinary stasis
family history
obesity
hypertension
diet
Calcium oxalate
most common (70%) stone; hypercalciuria and family history
Calcium phosphate
alkaline urine, hyperparathyroidism
Struvite
UTIs, proteus organisms
Uric acid and Cystine
gout; highly acidic urine
Renal Calculi Manifestations
colicky pain in flank area that radiates to lower abdomen and groin
bloody, cloudy or foul smelling urine
dysuria
frequency
genital discharge
nausea
vomiting
fever
chills
Hydronephrosis
abnormal dilation of the renal pelvis and the calyces of one or both kidneys
UNILATERAL= OBSTRUCTION ONE OR MORE URETERS
BILATERAL= OBSTRUCTION IN THE URETHRA
Causes/Complications of Hydronephrosis
CAUSES: urolithiasis, tumors, BPH, strictures, stenosis, congenital urologic defects
C: atrophy, necrosis, glomerular filtration cessation
Hydronephrosis Manifestations
colicky
flank pain/pressure
bloody, cloudy, or foul-smelling urine
dysuria

men
white
working with chemicals
smoking
excessive use of analgesics
experiencing recurrent UTIs
long-term catheter placement
chemo
radiation
Prostatic Hyperplasia
a common, nonmalignant enlargement of prostate gland that occurs as men age; exact cause unknown but may result in urinary stasis and UTIs
as prostate expands, it presses against urethra and obstructs urine flow
Prostatic Hyperplasia Possible Causes
declining testosterone and increasing estrogen levels are though to cause prostatic stromal cel proliferation, enlarging the prostate
OR stem cells in prostate do not mature and die as programmed, enlarging the prostate
Manifestations of Benign Prostatic Hyperplasia
frequency
urgency
retention
difficulty initiating urination
weak urinary stream
dribbling urine
nocturia
bladder distention
overflow incontinence
ED
Polycystic Kidney Disease
inherited disorder characterized by numerous grape-like clusters of fluid-filled cysts in both kidneys while compressing and eventually replacing the functional kidney tissue
exact trigger unknown, and prognosis and progression vary depending on type
Polycystic Kidney Disease Age-Related Manifestations
hematuria, nocturia, drowsiness
NEONATES: potter facies, large and symmetrical masses on flank, respiratory distress
ADULTS: hypertension, abdominal girth, swelling and tenderness/lumbar pain, enlarged and palpable kidneys
Polycystic Kidney Disease Complications
pyelonephritis
cyst rupture
retroperitoneal bleeding
renal failure
anemia
hypertension
renal calculi
Glomerulonephritis
acute/chronic bilateral inflammatory disorder of the glomeruli that typically follows a streptococcal infection; LEADING CAUSE OF RENAL FAILURE AND AFFECTS MEN MORE
inflammatory changes impair the kidneys ability to excrete waste and excess fluid
nephrotic and nephritic syndromes are most prevalent forms
Glomerular Diseases: Nephrotic Syndrome
results from antibody-antigen complexes lodging in the glomerular membrane, triggering activation of the complement system; DONT PROPERLY FILTER ALBUMIN
Causes/Complications of Nephrotic Syndrome
CAUSES: systemic diseases, gold therapy, idiopathic
C: risk for infection and atherosclerosis
Manifestations of Nephrotic Syndrome
increased glomerular capillary permeability leading to marked proteinuria, lipiduria, hypoalbuminemia, anasarca
dark and cloudy urine
immunoglobulins in urine
Glomerular Diseases: Nephritic Syndrome
inflammatory injury to glomeruli that can occur because of antibodies interacting with normally occurring antigens in glomeruli; DONT FILTER RBCs
Causes/Complications of Nephritic Syndrome
CAUSES: diseases that initiate the inflammatory response
C: impaired renal function
Manifestations of Nephritic Syndrome
gross hematuria
urinary casts and leukocytes
low GFR
azotemia (increased BUN and Cr)
oliguria
high BP
Acute Kidney Injury
sudden loss of renal function (often critically ill patients) generally reversible
RISK FACTORS: advanced age, autoimmune disorders, liver disease
asymptomatic
oliguric
diuretics
recovery
Prerenal Conditions (Acute Kidney Injury)
