25
What are some usual pre-existing conditions to pyelonephritis?
* Pregnancy
* Renal calculi
* Urinary catheterization
26
Why is an obstruction at the lower neck of the bladder of concern?
* It will cause retention of urine with high residual urine.
* The increasing pressure can led to backflow and as a consequence chronic pyelonephritis and renal atrophy.

31
Lower urine pH will produce what type of stones?
• Uric acid & cystine stones
32
Higher urine pH will produce what type of stones?
• Calcium & phosphate stones
33
What is the patho for struvite stones?
• Urinary obstruction/UTIs cause higher pH thus produce struvite stones
34
Where can urinary stones develop?
• in the bladder, kidneys, ureters or urethra
35
What are some clinical manifestations of bladder stones?
* Abdominal pain
* Dull costovertebral flank pain
* Hematuria

What common electrolyte do Thiazide diuretics and potassium citrate help reduce?
• Sodium
47
Why would a pt that a predisposing factor for stones (gout) take potassium citrate?
• Because it increases urine pH
48
Why do we want to limit dietary purines for pts w/ urinary caliculi?

What is overflow incontinence?
* Overflow incontinence occurs when you are unable to completely empty your bladder
* This leads to overflow, which leaks out unexpectedly

59
True or False
Stress incontinence is not related to psychological stress
• True
60
What is Urge incontinence?
* Urge incontinence occurs when you have a strong, sudden need to urinate that is difficult to delay.
