Culture and Sensitivity
What investigations may be useful for UTI in children or men or frequent UTI’s
Ultrasound
IVU
What study may rule out reflux and scarring in UTI
Isotope Study
Antibiotics for UTI
Amoxicillin, Cephalosporin, Trimethroprim
What is Reflux Nephropathy
UTI in Children

How much fluid should be taken in to prevent UTI
2/L a Day
Void every 2-3 Hours
What is inevitable with Indwelling Urinary Catheter
Colonisation
What does Bacteriuria need to be with UTI
> 10.5
Chronic Pylonephritis is what type of diagnosis
Radiological
which conditions associated with chronic pyelonephritis
Hypertension and CRF
what percentage of chronic pyelonephritis can progress to renal failure
15%
Schistosomiasis can cause which UTI
Cysitits
What percentage of Renal Blood Flow is Cardiac Output
20-25%
Resorption of fluid is diminished if what happens to fluid intake
increase then increase urine output
Which renal organ does not store urine
Ureters
As bladder increases pressure as it fills what happens to ureters
the ureters close off and stops reflux of urine
Normal Bacteriostatic properties of normal urinary tract
Low pH, High Osmolarity and High Ammonia (NH3) content of normal urine
Prostatic secretions are said to be
bacteriostatic
Urinary tract except for where is sterile
Terminal Urethra
Suprapubic aspirated of urine. is
sterile
Urine specimen is always
Contaminated
In Mid Stream Specimen Urine what happens to urethral flora
diminished but always present
Urethral Flora will always do what in culture
Grow
In Mid Stream Specimen Sample there is no such thing as
negative result
If MSSU Culture is 10.3-10.4 then what is the percentage chance of infection if no symptoms
50%
Route of UTI infection is almost always
ascending
