Chap 18 cont 4

urine and fecal collection

Urine can be obtained by several methods free catch, manual expression of the bladder, cystocentesis and from catheterization of the bladder
free catch are good for route urinalysis, not for cultures as they contain bacteria, cells and debris from the skin, hair and genitoruinary tract.
manual bladder expression can be used for route urinalysis, not for cultures
cystocentesis is the percutaneous aspiration of urine from the bladder, used to obtain a sterile sample for analysis and/or culture and sensitivity testing
cystocentesis can aid in localization of hematuria, pyuria and bacteriuria
excessive pressure from a full bladder might lead to leakage of urine from the puncture site when the needle is withdrawn
removal of all of the urine via cystocentesis can increases the risk of contact between the needle and the bladder wall resulting in bladder damage
indications for urethral catheterization are urine collection, emptying the bladder, relieving a urethral obstruction, allowing access to the ruinary tract for radiographic studies, and treating patients with conditions where indwelling catheters are needed.
Indwelling catheters are placed for patients with neurologic impairment, traumatic donditioins, blocked cats
Urine should be measured in these patients at a rate of 1 to 2 mls of urin per kilogram of body weight per hour
a new catheter should be replaced every 4 to 5 days.
