Post procedure
Renal biopsy preprocedure
Post biopsy
- used for someone with recurrent infections
- Dye allergies, NPO, expect flushing & salty taste
- NPO night before, enemas
- pink-tinged urine is common, bright red urine & blood clots not common
- clotting studies (PT, PTT, INR)
- supine bedrest 8Hrs, pressure to site for 30min, avoid lifting 2 weeks
Disorders to push fluids

UTI is
Manifestations
Interventions
Preventing UTI
Inflammation of bladder also known as cystitis
- dysuria, cloudy, urgency, frequency, foul odor, Suprapubic pressure
- urine culture is gold standard test, increase fluid intake 3L per day
- void 2-3hrs, perineal care wipe front to back, no bubble baths, void after intercourse, cotton pants, vaginal creams in menopause
Urosepsis most common organism
Manifestations
Interventions
Urethritis assessment
Interventions
- E. coli
- Fever, altered mental status
- Give IV antibiotics & send urine culture
- burning with urination, frequency & urgency
- test for STDs (no symptoms w chlamydia)
Pyelonephritis common cause
Manifestations
Interventions
- ascending infection from a previous untreated UTI
- UTI symptoms + high fever, flank pain, CVA TENDERNESS
- fluids, antibiotics, pain meds, antiemetic
Glomerulonephritis is
Complications
Clinical manifestations
Interventions
- destruction & inflammation of glomeruli caused by untreated strep (pharyngitis or tonsillitis 2-3weeks prior)
- low urine output, fluid overload, High BP
- Hematuria (main ID), proteinuria, crackles, Low GFR, high BUN & Cr
- fluid restriction, I&Os, daily weight, avoid NSAIDS & vancomycin
Nephrotic syndrome assessment
Interventions
Hydronephrosis can lead to
Assessment
Interventions
- proteinuria, hypoalbuminemia, Hyperlipidemia, anemia, edema
- bedrest, low protein diet, fluid restriction
- renal failure due to obstruction of urine flow
- HTN, headache, flank pain
- monitor for diuresis, push fluid to flush stone out
Polysistic kidney disease leads to
Interventions
- renal failure
- cyst rupture, drain abscesses, prepare for dialysis or transplant
Urolithiasis & nephrolithiasis is
Manifestations
Complications of obstruction
Best test
Causes
Interventions
- formation of calculi or stones
- sudden onset of severe flank pain, dysuria, nausea
- hydronephrosis, renal failure, infection
- computed tomography CT, size & location of stone
- family Hx, purine rich diet, calcium diet, dehydration, uric acid
- pain meds, flomax to dilate ureters, strain all urine, do not massage flank area
Prostatitis manifestations
Interventions
BPH after age 50
BPH can cause
Surgical procedure for BPH
Post op & return quality
- fever, chills, dysuria, boggy prostate, hematuria
- antibiotics, analgesics, masturbation, prostate massage
- pt should be screened for prostate cancer
- Postrenal failure due to obstruction
- Transurethral resection of the prostate (TURP)
- continuous bladder irrigation to prevent clot formation, returns should be red to pink; report bright red clots STAT
Kidney transplantation watch out for
Interventions for rejection
Education
- gross hematuria, blood clots, graft rejection; fever, malaise, WBC count, deteriorating renal fxn, anemia
- removal of kidney, high doses of corticosteroids, immunosuppressive meds
- avoid contact sports, avoid exposure to people with infections, immunosuppressive therapy for life
Prerenal failure causes
Intrarenal causes
Postrenal causes
- decreased perfusion, vascular failure, Hypovolemia
- tubular necrosis, nephrotoxicity
- obstruction of outflow
Acute renal failure is
Causes
Oliguric phase
Diuretic phase
Recovery phase
- sudden loss of kidney function, reversible
- infection, obstruction, dehydration, ischemia, toxic substances
- 8-15 days, GFR decreases, oliguria, HTN, elevated BUN & Cr
- GFR increases, urine output rises & then diuresis, loss of electrolytes, decline in BUN & Cr
- 1-2 years, normal urine volume, increase in strength, BUN stable, can develop chronic renal failure
Chronic renal failure is
Stage 1: diminished renal reserve
Stage 2: renal insufficiency
Stage 3: end stage
Causes
Manifestations
- irreversible damage & results in end stage renal disease
- reduced renal fxn, healthier kidney compensates, nocturia & polyuria, no accumulation of metabolic waste
- metabolic wastes accumulate, oliguria & edema occur
- excessive accumulation of metabolic wastes, kidneys can’t maintain homeostasis, dialysis is required
- ARF, chronic obstruction, recurrent infections, HTN, metabolic disorders
- kussmaul respirations, muscle twitching, anorexia, confusion & lethargy, oliguria, proteinuria, azotemia, uremic frost, fluid overload
Special problems in renal failure
Hypocalcemia
Hyperkalemia (peaked T, wide QRS)
HTN
Hyper or Hypovolemia
Metabolic acidosis
Neuro changes
Muscle cramps
Anemia
Hypocalcemia in renal failure leads to
Treating anemia
Hemodialysis preferred access
Hemodialysis interventions
- secondary hyperparathyroidism due to compensation
- always hang blood with NS, if adverse rxn - stop infusion, change tubing & send to lab
- AV fistula ; auscultate for bruit & palpate for thrill to assess patency
- weigh before & after, hold BP drugs day of dialysis
Disequilibrium syndrome is
Manifestations
Interventions
- common in 1st dialysis: removing too much fluid too fast causes altered LOC; decrease rate of dialysis
- restlessness, confusion, seizure, HTN, headache
- decrease rate of dialysis, notify physician,
AV shunt advantages
Disadvantages
AV fistula advantages
Disadvantages
Interventions for fistula & graft
- can be used immediately, no venipuncture
- external danger of dislodging, risk for infection or hemorrhage
- access of choice, less danger of clotting or hemorrhage, used indefinitely, decreased infection
- takes 4-6 weeks before use, arterial steal syndrome (hand discolored & decreased capillary refill), needle insertion required
- don’t measure BP or place IV on affected arm, monitor for infection & steal syndrome, palpate pulses, thrill & bruits,
Peritoneal dialysis if outflow is insufficient
Inflow, dwell time, outflow
Peritonitis signs
Characteristics of outflow
- change position of patient (side to side, or sit upright)
- warmed dialysate, inflow bag higher than abdomen, hang 4-8hrs, outflow bag lower than abdomen lvl
- fever, board like rigid abdomen, guarding, tenderness
- during 1st exchanges may be bloody, should be clear after (brown = bowel perforation) (urine color = bladder perforation) (cloudy = peritonitis)
Hypopituitarism is
Interventions
Hyperpituitarism is
Interventions
What is hypophysectomy & complications
Post-op
- insufficient growth hormone, resulting in delayed growth & development
- administer human growth hormone replacement
- excess growth hormone : gigantism (before epiphyseal plates close) or acromegaly (after closure of epiphyseal plates)
- skin care, help with ambulation, hypophysectomy
- removal of pituitary ; increased ICP, bleeding, meningitis
- elevate HOB, neuro exams, monitor post-nasal drip (halo ring & glucose in CSF), glucocorticoids
