Glomerulonephritis Immunologic process resulting in inflammation of the glomerulus. 3 rd leading cause of renal failure in the US. Autoantibodies production stimulated by exogenous agents (hydrocarbon, viruses (hep. B, C, rubella, bacteria (streptococcal), chemicals, drugs ), diseases or endogenous (SLE) Clinical manifestations: hematuria, excretion of RBCs, WBC, casts, decrease GFR, azotemia, oliguria, hypertension, periorbital edema

Acute Poststreptococcal Glomerulonephritis Clinical manifestations and complications- develops 5-21 days post infection of throat by strep. Diagnostics: hx, physical assessment, CBC, throat swab Tx; rest, sodium and fluid restriction, diuretics, antihypertensive therapy, emotional support, education, decrease dietary protein.Antibiotics(if strep still present), corticosteroids.

Chronic glomerulonephritis End stage of acute disease Symptoms: proteinuria, hematuia slow development of uremia, progresses toward renal failure Dignostic: u/a, vs, ultrasound, CT, renal biopsy Tx-supportive an symptomatic: control hypertension and uti’s, protein and phosphate restriction may slow the rate of progression.

Nephrotic Syndrome results when: glomerulus is permeable to plasma protein, causing proteinuria, low plasma albumin and tissue edema Symptoms: peripheral edema, massive proteinuria, hypertension,, hyperlipidemia, hypoalbuminemia, ascites, anasarca, calcium abnormalitiesaltered immune response, altered coagulation (hyper) Collaborative care-symptom management; relieve edema, cure primary disease, low Na diet, low protein, diuretics, NSAIDs, anticoagulant therapy, corticosteroids.

Causes pyelonephritis and renal atropy. If one kidney involved, other will compensate. Symptoms: alterations in kidney function (per assessment, labs; increased BUN, creatinine, oliguria or anuria.

Urinary Tract Calculi 500,000 people/yr develop lithiasis, more common in warm climates (dehydration) Various types of calculi (p.1170), recurrence of stones -50%. Clinical manifestations-Pain in flank area (depends on location of stone), severe, hematurin, reanl colic, N&V, Diagnostic studies-u/a, culture,VP, ultrasound, cystoscopy. Collaborative care-keep urine dilute and free flowing,reduces risk of formation., analyze stone to determine cause and prevent recurrance; screening of urine, CBC, urine ph. – Endourologic procedure-bladder-cystoscopy, ureteroscopes, – Lithotripsy-pulverizes stons with ultasonic vibrations. – Surgical therapy-nephrolithotomy-incision into kidney to remove stone

Strictures Ureteral and urethral strictures-narrowing of lumen, associated with unintended reslut of sugical intervention, adhesions, scars or genetic Symptoms: diminshed force of urinary stream, staining to void, split urine stream, frequency, nocturia. Can lead to urinary retention and uti. Diagnostic; retrograde urethrography (RUG). Management; dilation of stricture by stent placemtn, self-catherterization, or urethroplasty.

Results in hypertension and low perfusion to kidneys (hypertension, hematuria) Can result in sclerosis to one or both kidneys, impacting filtering capacity ( elevated creatinine) Goals of therapy; control hypertension, increase profusion. Collaborative care; percutaneous transluminal renal angioplasty, surgical revascularization of kidney.

RAS Clinical symptoms: Sudden onset of hypertension, asymmetry in kidney size on imaging studies Diagnosis based on hx, clinical findings, lab, imaging, 24 hr urine. Goals of therapy; control hypertension, increase profusion (ACE inhibitors, diuretics, betablockers, and calcium channel blockers) Collaborative care; percutaneous transluminal renal angioplasty, surgical revascularization of kidney

Polycystic Kidney Disease Most common life-threatening genetic disease in the world, affecting 600,000 in US, 12.5/world!! Accounts for 10-15% of chronic kidney disease. 2 forms (childhood (rare), adult). Adult: autosomal disorder, involves both kidneys, cysts destroy surrounding tissue, filled with blood, pus. Clinical manifestations-hypertension, hematuria, feeling of heaviness in back, may have frequent uti or kidney infection, chronic pain (abdominal or flank), decreawed abiltiy to concentrate urine, palpable kidneys, effects other organs

Collaborative care; no specific tx. Major aim is to prevent infections and symptoms. Kidney transplant is only cure. Nursing interventions: management of end- stage renal disease.
