Class 10:urinary incontinence- retention

bladder retention

inability to empty the bladder

over distended bladder

This causes the fundus to displace

over distention causes the

detrusor muscle to not be able to contract

hydronephrosis

abnormal condition of water in the kidney

kidney becomes stretched and swollen due to build up of urine

vesicoureteral reflux (VUR)

disorder caused by the failure of urine to pass through the ureters to the bladder, usually due to impairment of the valve between the ureter and bladder or obstruction in the ureter

Urine move back to kidneys

mechanical obstruction of bladder

something is physically blocking passage for urine

renal calculi

kidney stones

who is at highest risk for bph

old men

risk factors for urinary retention

old age

men

diabetes

constipation

history of uti

immobility

medication

why does constipation cause urinary retention

the fecal matter puts pressure on bladder

S/S of acute retention

occurs suddenly and painful inability to void despite full bladder

possible EXTREME PAIN

severe bladder distention

Medical Emergency

Bloating

Caused by: medications, surgical procedures, Uti, excessive fluid intake, BPH

s/s of chronic retention

PAINLESS: associated with increase residual urine volume

difficulty starting and maintaining urination

weak flow

can lead to overflow incontinence

Bladder scan to find residual urine volume

is done to determine if the client emptied the bladder completely.

chronic retention range

25ml to 50ml urine at a time in frequent intervals

Firm distended bladder, may be

displaced to one side of midline.

(may cause urinary retention)

percussion will have a

dull tone over bladder

if residual urine is greater then 100mL then the

individual has urinary retention

How to promote urinary elimination

encourage normal voiding pattern

apply warmth to relax sphincter

warm caffeine free drinks

cholinergic medications help

stimulates the bladder to contract more (detrusor muscle)

1 ounce equals

30 mL

2 tablespoons

Pathophysiology of Urinary Retention

1. Bladder emptying is impaired

2. Urine accumulates

3. Bladder becomes overdistended

4. Overdistention causes poor contractility of detrusor muscle

5. Furter Impairment of Urination
