Q

What are the risk factors for UTI?

A
  • Reduced urine flow (obstruction, inadequate fluid, neurogenic bladder)
  • Promote colonization (Sexual activity, recent Abx)

28
When must a patient with Pyelonephritis follow up?
48-72 hours
29
What are some of the indications for hospitalization in acute Pyelonephritis?
- Critically ill and hemodynamically unstable - Persistent fever - suspected obstruction - metabolic derangement - cant take PO - Compliance concerns
30

Bladder pain syndrome (BPS) and painful bladder syndrome (PBS)
33
What is a chronic and debilitating conditions characterized by bladder pain?
IC
34
How is IC diagnosed?
- Usually a diagnosis of exclusion - UA with microscopy and urine culture (generally unremarkable) - Urine cytology - STI testing - PVR - Cystocopy
35
What may be seen on cystoscopy with IC?
-May identify urothelium (glomerulations and hunner lesions)
36
What is the first line treatment for IC?
- Self care and behavioral modifications - Diet modifications - bladder retraining - low impact exercise - psychotherapy - urinary analgesics
37

38
What is the third line therapy for IC?
- Cystoscopy with short duration, low pressure hydrodistention - Intravesical instillation of GAGs - Intravesical Dimetheyl Sulfoxide (DMSO)
39
What is fourth line treatment for IC?
- Intradestrusor botulinum toxin | - Sacral neuromodulation
40
What is a syndrome characterized by urinary urgency, with or without incontinence, often accompanies by nocturnal and urinary frequency?
Overactive bladder
41
What is the etiology of OAB?
Detrusor muscle overactivity, leading to involuntary bladder contractions that cause leakage
42
What is the first line treatment for OAB?
- Kegel exercises - Lifestyle and behavioral modifications - Bladder training
43
