Common indications for urinary catheterization include acute or chronic urinary retention (which can damage the kidneys) from conditions such as benign prostatic hyperplasia, orthopedic procedures that may limit a patient's movement, the need for accurate monitoring of input and output (such as in an ICU), urinary incontinence that may compromise the ability to heal wounds, and the effects of ...
The relative size of an indwelling urinary catheter is described using French units (Fr). [6] Alternatively, the size of a 10 Fr catheter might be expressed as 10 Ch (Charriere units – named after a 19th century French scientific instrument maker, Joseph-Frédéric-Benoît Charrière). The most common sizes are 10 Fr to 28 Fr. 1 Fr is ...
Urinalysis is commonly used to help diagnose urinary tract infections, but the significance of the results depends on the broader clinical situation. [13] In the setting of UTI symptoms, positive dipstick results for nitrite and leukocyte esterase are strongly suggestive of a UTI, [ 138 ] [ 139 ] but negative results do not rule it out if there ...
A urine collection device or UCD is a device that allows the collection of urine for analysis (as in medical or forensic urinalysis) or for purposes of simple elimination (as in vehicles engaged in long voyages and not equipped with toilets, particularly aircraft and spacecraft).

Automatic analysis of urine test strips using automated urine test strip analysers is a well-established practice in modern-day urinalysis. They can measure calcium , blood, glucose, bilirubin, urobilinogen, ketones, leukocytes, creatinine , microalbumin , pH, ascorbic acid and protein.
If there is a urinary catheter, the catheter should be clamped immediately after drinking the water. The person should not pass any urine until the scan is over. [3] If the urinary bladder is the subject of interest, a person will be asked to pass urine and the amount of urine left in the bladder may be recorded. [1]
Postrenal AKI refers to acute kidney injury caused by disease states downstream of the kidney and most often occurs as a consequence of urinary tract obstruction. This may be related to benign prostatic hyperplasia, kidney stones, obstructed urinary catheter, bladder stones, or cancer of the bladder, ureters, or prostate.
