5 Hematuria

6 According to the American Urological Association, the presence of three or more red blood cells (RBCs) per high-powered field (HPF) in two of three urine samples is the generally accepted definition of hematuria.

7 Common Causes of Hematuria  Glomerular causes Familial causes Fabry's disease Hereditary nephritis (Alport's syndrome) Nail-patella syndrome Thin basement-membrane disease Primary glomerulonephritis Focal segmental glomerulonephritis Goodpasture's disease Henoch-Schönlein purpura IgA nephropathy (Berger's disease) Mesangioproliferative glomerulonephritis Postinfectious glomerulonephritis Rapidly progressive glomerulonephritis Secondary glomerulonephritis Hemolytic-uremic syndrome Systemic lupus nephritis Thrombotic thrombocytopenic purpura Vasculitis  Renal causes Arteriovenous malformation Hypercalciuria Hyperuricosuria Loin pain-hematuria syndrome Malignant hypertension Medullary sponge kidney Metabolic causes Papillary necrosis Polycystic kidney disease Renal artery embolism Renal vein thrombosis Sickle cell disease or trait Tubulointerstitial causes Vascular cause

8 Common Causes of Hematuria  Urologic causes Benign prostatic hyperplasia Cancer (kidney, ureteral, bladder, prostate, and urethral) Cystitis/pyelonephritis Nephrolithiasis Prostatitis Schistosoma haematobium infection Tuberculosis Other causes Drugs (e.g., NSAIDs, heparin, warfarin [Coumadin], cyclophosphamide [Cytoxan]) Trauma (e.g., contact sports, running, Foley catheter)

9 Microscopic examination may detect: RBC casts Dysmorphic RBCs.

29 63-year-old man was found to have microscopic hematuria on urinalysis. The remainder of the urinalysis was normal, as was the physical exam. The patient did not complain of any fever, weight loss, pain, malaise, weakness, or urinary tract symptoms.

30 Laboratory results showed the following: –Electrolytes: normal –Hct57%Hb19 g/dL –BUN12 mg/dLCreatinine0.7 mg/dL –WBC7,450/mm3 with a normal differential –Urine cytology: negative

31 Work-up for the hematuria was begun with: noninvasive imaging studies, which included a renal ultrasound examination and an intravenous pyelogram. A mass was seen in the left kidney with both imaging studies. A CT scan has been performed

32

33 The patient underwent nephrectomy.

37 1.What is the classic triad of presenting symptoms of renal cell carcinoma? 2.What is the typical age of patients with renal cell carcinoma (RCC)? 3.What is the most common renal tumor in children?

43 4) What paraneoplastic syndromes are associated with renal cell carcinoma?

44 Staging Stage 1 - Confined to the kidney Stage 2 - Involvement of perinephric fat but Gerota's fascia intact Stage 3 - Spread into renal vein Stage 4 - Spread into adjacent or distant organs Prognosis depends on pathological stage, tumour size, nuclear grade and histological type

45 5)Where is the location? 6)What is the name of the tumor?

47 A previously healthy 35-year-old man complained of recent fatigue and swelling of his feet and ankles. He also noted puffy eyes. Physical exam revealed an a febrile man with lower extremity edema extending to the knee, periorbital edema, and a small amount of ascites.

48 Laboratory results were: Urinalysis: –protein - 4+ –Micro:rare RBCs, no WBCs, many oval fat bodies Serum –Creatinine:0.8 mg/dL –BUN18 mg/dL –Albumin2.8 g/dL –Hematocrit40% –Liver function testsnormal –Triglycerides:400 mg/dL –Cholesterol:375 mg/dL –24-hr urine protein11.2 gm/24 hr

49 1.What is the clinical syndrome of this patient? 2.What is the most common cause of the disease in adult and in children?

50 Drug history was negative. ANA, HIV, and hepatitis serologies were negative. A renal biopsy was performed.

51 3)Is any inflammation seen?

52 4)What is the typical sign of this disease?

53

54

55 5) Are the spikes part of the deposits? 6) Based on the results of light microscopy, immunofluorescence, and electron microscopy of the renal biopsy specimen, what is the patient's diagnosis?
