A

much more common in women, acute onset of irritative voiding sx (frequency, urgency, dysuria), often without fever, may have suprapubic discomfort; PE often unremarkable aside from suprapubic discomfort; for men evaluate prostate for enlargement or irregularity

Q

Any positive dipstick result requires what?

A

microscopy, gram stain, C&S

24
Q

What is the initial imaging for acute cystitis?

A

none for women, men imaging for prostate (trans rectal US, CT pelvis) and/or cystoscopy

25
Q

What is the initial imaging for BPH?

A

transrectal US, possible bladder scan with PVR

26
Q

What imaging should be performed for urge and stress incontinence?

A

none

27
Q

What initial imaging should be performed for overflow incontinence?

A

bladder US with PVR (>200); additional testing includes CT pelvis (case specific based on PE)

28
Q

What investigations should be done for acute cystitis?

A

none unless fails to resolve, or cystoscopy

29
Q

What procedural investigations should be done for BPH?

A

cystoscopy (and/or CT pelvis)

30
Q

What procedural investigations should be done for urge and stress incontinence?

A

none

31
Q

What procedural investigations should be done for overflow incontinence?

A

cystoscopy (and/or CT pelvis

32
Q

What are the lifestyle modifications recommended for BPH?

A

limit fluids before bedtime and travel, limit mild diuretics such as caffeine and alcohol, avoid constipation, Kegel exercises at time urinary urgency, timed voiding rather than waiting for sensation, double voiding technique

33
Q

What medications can be given for BPH?

A

A-adrenergic receptor blockers, phosphodiesterase type 5 inhibitors, 5-alpha reductase inhibitors to prevent progression; concurrent overactive bladder sx (B-3 adrenergic agonists, anticholinergics)

34
Q

What surgical options exist for BPH?

A

transurethral ablation (TURP) to total prostatectomy

35
Q

What is the MOA for alpha-adrenergic blockers?

A

affect on prostatic smooth muscle leading to relaxation of smooth M of the bladder neck and prostatic urethra

36
Q

What are the side effects for alpha adrenergic blockers?

A

dizziness, rhinitis, hypotension

37
Q

What are the side effects for PDE5 inhibitors?

A

relatively rare (HA, flushing)

38
Q

What is the MOA for 5-a reductase inhibitors?

A

Prevent progression; blocks conversion of testosterone to DHT

39
Q

What are the side effects for 5-a reductase inhibitors?

A

suppression of PSA level, sexual dysfunction

40
Q

What is the MOA for B-3 adrenergic agonists?

A

effective with overactive bladder sx via detrusor relaxation

41
Q

What are the side effects for B3 adrenergic agonists?

A

elevated BP

42
Q

What is the MOA for anticholingerics (antimuscarinic)?

A

decrease involuntary detrusor contractions triggered by ACh; contraindicated gastric retention and agile closure glaucoma

43
Q

What are the side effects for anticholingergics?

A

dry mouth, blurred vision for near objects, tachycardia, drowsiness, decreased cognitive function, consitpation

44
Q

What is the MOA for OTC Saw Palmetto?

A

unclear and not recommended

45
Q

What are the lifestyle recommendations for acute cystitis?

A

regular bladder emptying, particularly after intercourse, increase free water to maintain clear to light yellow urine

46
Q

What additional tx exists for acute cystitis?

A

Abx, phenazopyridine (urinary analgesic OTC such as AZO or pyridium), topical estrogen for post menopausal women with >3 UTI/year

47
Q

What makes pt high risk?

A

Any one of the following in 3 months prior to presentation of acute cystitis: inpatient stay in a health care facility, use of fluoroquinolone, TMP/SMZ, or broad spectrum beta lactam, presence of MDR urinary isolate, travel to parts of the world with high rates of MDR organisms

48
Q

Follow up is required for pts with what initial presentation?

A

hematuria; asymptomatic hematuria may indicate pathology anywhere in the urinary system ranging from glomerular disease to occult cancer

49
Q

What are the characteristics for extraglomerular hematuria?

A

red or pink in color, clots may be present, proteinuria of <500mg/day, RBC morphology normal, RBC casts absent

50
Q

What are the characteristics for glomerular hematuria?

A

Red, smoky brown or Coca-cola color, clots absent, proteinuria may be >500mg/day, some RBCs are dysmorphic, RBC casts may be present

51
Q

What is the tx + procedures for urge incontinence?

A
  1. bladder training (scheduled voiding) + Kegels; 2. medications if behavior approach fails (anitmuscarinic agents or B3 agonists)
52
Q

What are the Tx + procedures for stress incontinence?

A

Lifestyle modifications (limit caffeine, fluid intake), Kegels; pessary or vaginal cones; surgery has a high cure rate of 96%

53
Q

What are the tx + procedures for overflow incontinence?

A

bladder decompression (catheter placement); mediation admin with or wo intermittent self catheterization (MC meds are alpha blockers); surgery for cystocele, uterine prolapse, or BPH if medical management fails; sacral nerve stimulation for neurogenic underactivity

54
Q

What is the chapman point for the bladder?

A

anterior is immediately surrounding the umbilicus and on pubic symphysis; posterior point on the superior edge of L2 TP

55
Q

What is the chapman point for the urethra?

A

anterior point superior pubic symphysis, posterior point superior edge of L2 TP
