25
Bothersome symptoms are...
managed with lifestyle modifications, medications, and surgery
26
First-line medications for BPH
Alpha blockers
27
Evidence-based research shows dietary supplements...
are not recommended for the management of BPH | palmetto, pygeum, cernilton, beta sitosterols and acupuncture
28
BPH Nursing Assessment
- >40 yrs should be assessed - health hx - physical exam - dx tests - IPSS scale
29
Health hx includes...
- risk factors - pain - urinary elimination patterns - hematuria
30
Physical exam includes...
DRE
31
Dx tests
- UA - Urine flow rate test - Postvoid residual - Pressure flow study - urine culture for blood or infection - cytoscopy - DRE
32
IPSS
International Prostate Symptom Score - used to assess symptoms - collects data about several subjective factors
33
Nursing Diagnosis'
- impaired urinary elimination - risk for infection related to urinary retention -overflow urinary incontinence related to sphincter blockage secondary to enlarged prostate - acute pain related to bladder distention - deficient knowledge related to effect of prostate surgery on sexuality
34
Nursing Care/Responsibilites
- therapeutic communication - answering patient questions - providing emotional support - patient teaching
35
Patient teaching for nursing intervention
- self-care - proper admin of meds - med side effects to expect - symptoms to report to physician - nutrition
36
3 types of medications for BPH therapy
1. 5-alpha reductase inhibitors 2. Alpha-adrenergic blockers 3. Anticholinergic
37
5-alpha reductase inhibitors
"ide" - dutasteride - finasteride
38
Alpha-adrenergic blockers
"sin/soin/in" - doxazosin - prazosin - tamsulsoin - terazosin
39
anticholinergic
tolterodine
40
Treatment with medications is based on two considerations
1. Hyperplastic tissue is androgen-dependent | 2. Smooth muscle contraction within the prostate can exacerbate urinary obstruction
41
What does 5-alpha reductase inhibitors do?
inhibit conversion of testosterone to DHT and cause enlarged prostate to shrink in size
42
Side effects of 5-alpha reductase inhibitors
- impotence - decreased libido - decreased volume of ejaculation
43
What is used to treat mild prostate enlargement?
-finasteride or dutasteride
44
What does Alpha-adrenergic antagonists do?
relax smooth muscle of prostate and bladder neck to relieve obstruction and increased the flow of urine
45
Side effects of alpha-adrenergic antagonists
orthostatic hypotension
46
Patient teaching for alpha-adrenergic antagonists
- slow position changes - monitor BP - check with HCP before taking OTC cough, cold, allergies
47
Why to avoid OTC cough, cold, and allergy meds while taking alpha-adrenergic antagonists ?
OTCs may contain adrenergic agents
48
Research shows that using _______ and _______ together is more effective than using each alone to relieve manifestations and prevent BPH progression in clients with moderate or enlarged prostate
Finasteride and Doxazosin
49
Medications that worsen BPH symptoms
1. Alpha-adrenergic agents 2. Drugs with anticholinergic side effects 3. Testosterone and other anabolic steroids
50
How does Alpha-adrenergic agents affect BPH condition?
-activate alpha1-adrenergic receptors in bladder neck, causing urine flow restriction
51
How do drugs with anticholinergic side effects affect BPH condition?
adversely affects BPH
52
How do testosterone and other anabolic steroids affect BPH condition?
- increase prostate enlargement | - increases physical obstruction of the urethra
53
Older men should avoid what meds?
1. alpha-adrenergic agents 2. drugs w/ anticholinergic side effects 3. testosterone and other anabolic steroids
54
Lifestyle changes needed for men with mild BPH
- urinating at first urge - avoiding alcohol and caffeine - drinking small amounts of fluids throughout the day - avoiding drinking fluids within 2 hrs at bedtime - avoiding OTC cold and sinus meds that contain decongestants or antihistamines - exercising regularly including Kegel - reducing stress
55
Mild BPH symptoms
"watchful waiting" and lifestyle change -usually clear up with no treatment in one third men
56
Nursing Interventions
- absorbent pads - catheter - dietary supplements (not proven) - lifestyle modifications
57
Surgical intervention for BPH
TURP
58
TURP
Transurethral resection of the prostate - obstructing prostate tissue is removed with wire loop of a resectoscope and electrocautery inserted through the urethra - tissue is flushed into bladder with fluid and then flushed out at the end of the operation
59
Risks with TURP
- hemorrhage - clot retention - inability to void - UTI - incontinence - impotence - retrograde ejaculation
60
postop nursing care
- 3 way cath irrigation - maintain traction of foley - maintain irrigation (color) - monitor I & Os - monitor for TURP syndrome
61
TURP syndrome
volume excess and hyponatermia
62
Manifestations of TURP syndrome
- hyponatermia - decreased hematocrit - HTN - bradycardia - nausea - confusion - crackles - infection - edema - impotence
63
The manifestations of TURP syndrome results from?
systemic absorption of irrigating fluids during and after surgery if goes untreated....dysrhythmias and/or seizures
64
CBI
Continuous bladder irrigation -prevents formation of blood clots which can obstruct urinary output
65
What the nurse looks for while on CBI?
- output urine light pink/rose or colorless | - assess q 1-2hrs for color, consistency of amt, and presence blood clots
66
Frank blood after TURP
means hemorrhage/active bleeding -assess pt and alert MD
67
Complaints of bladder spasms after TURP
could be expected, will feel full, cath could be blocked - assess pt, cath patent with flowing fluid - meds to help with contraction
68
No output after TURP
catheter blocked - increased fluids to try to flush clot - notify MD
69
Reports discomfort or leaking around cath after TURP
- may be expected | - go from there
