-
AKI
- Acute loss of renal function, usually 24-48 hours
- generally resolves in 3 months of onset
- -can progress to acute renal failure if oliguria
- (<400cc/day) and increased serum creat (0.5
- mg/dL/day)
- RIFLE criteria OR pre, intra, post renal method
-
Acute renal insufficiency
- -BUN increased out of proportion to
- Creat
- -reversible w/ proper therapy
- -obstruction, ATN,contrast media
-
-
azotemia
- Abnormally high levels of nitrogencontaining
- compounds (such as urea,
- creatinine, various body waste
- compounds, and other nitrogen-rich compounds) in the blood
- BUN >100mg/dL
-
BPH
- Progressive condition caused by enlargement of the prostate gland, usually inmen over 50yrs
- -50% of men >50yrs
- -80% of men >80yrs
- May be response of prostate to androgens over time
- -Dietary fat may play a role
-
BPH labs/dx
- UA:
- pyuria suggests infection
- hematuria may indicate malignancy
- Ucx:
- r/o UTI if irritative symptoms present
- BUN/Creat to assess renal insufficiency
- PSA for respective decade
- 50 yeers start PSA unless hx or Af. Amer = 30 years
- transrectal ultrasound for nodule or elevated PSA
-
BPH mgmt
- Mild? - watchful waiting, refer to urologist
- Alpha blockers (relax muscle fibers in prostate and capsule and internal urethral sphincter)
- -Terazosin 1mg at bedtime, up to 10mg
- -Prazosin 1-5mg PO BID
- -Doxazosin 1-8mg daily
- -Combo (tamsulosin 0.4 or 0.8mg daily, urotaxtral, silodosin)
- Hormonal manipulation
- -Finasteride 5mg/day x 6mo (blocks conversion of testosterone to dihydrotestosterone, shrinks epithelial part of prostate)
- -Dutasteride 0.5mg daily
- -Estrogens, androgens, GnRH if finasteride not tolerated
- Phytotherpay:
- -saw palmetto berry (decreases PSA, no evidence to suggest decreases ca risk)
- -echinacea
- -pumpkin/squash
- -stinging nettle
- -rye
- -leaves of trembling poplar
- Surgery:
- -TURP
- -TUIP (no tissue resected, can be done outpatient)
-
BPH meds to avoid
- Act on alpha receptors to enhance prostate muscle tone (increases obstruction)
- -decongestants and diuretics
- Decrease bladder muscle contraction (increases
- retention)
- -anticholinergics (antihistamines), bowel
- antispasmodics, TCAs, opiates, antipsychotics (SSRIs)
-
BPH s/s
Irritative: freq, dysuria, urgency, nocturia, incontinence
Obstructive: hesitancy, straining starting and stopping, dribbling, retention decreased force/caliber of stream, sensation of incomplete bladder emptying, double voiding
*size doesnt correlate with severity of symptoms or degree of obstruction
- DRE: smooth and rubbery feel normal, if enlarged, nodular, hard possible mallignancy
- Start DRE at 40 YO
-
CKD mgmt
- -diuretics for volume overload
- -monitor and tx metabolic acidosis PRN
- -monitor ytes (hypercalcemia in chronic
- renal failure)
- -treat anemia PRN
- -treat azotemia (BUN>100mg/dL) w/ RRT/dialysis
-
Chronic renal insufficiency/failure
- Progressive impairment over months to years
- (chronic renal failure)
- -steady increase in BUN and creat (10:1 ratio)
- -intrinsic kidney damage irreversible, but
- progression can be slowed
- -GFR <60mL/min over 3 mo +/- kidney
- damage
