Renal Conditions: Comprehensive Quick-Reference Chart
| Feature | Urinary Tract Infection (UTI) | Glomerulonephritis (GN) | Chronic Renal Failure (CRF / CKD) | Nephrotic Syndrome | Hematuria |
|---|---|---|---|---|---|
| Definition | Bacterial infection of the urinary tract (bladder = cystitis; kidney = pyelonephritis; prostate = prostatitis) | Inflammatory disorder of the glomeruli causing hematuria and proteinuria; may be acute, rapidly progressive, or chronic | Progressive, irreversible loss of nephron mass leading to sustained decline in GFR (<60 mL/min for >3 months) | Glomerular permeability defect causing massive proteinuria, hypoalbuminemia, edema, and hyperlipidemia | Presence of red blood cells in urine - gross (visible) or microscopic (>5 RBCs/hpf) |
| Causes | - E. coli (most common, 80-85%) - Klebsiella, Proteus, Enterococcus - Catheter/instrumentation, sexual activity, structural anomalies, obstruction, vesicoureteral reflux, immunosuppression | - Post-streptococcal (Group A beta-hemolytic strep) - IgA nephropathy - Lupus nephritis (SLE) - Henoch-Schonlein purpura - ANCA vasculitis - Membranoproliferative GN - Hepatitis B/C | - Diabetes mellitus (leading cause) - Hypertension - Chronic GN - Polycystic kidney disease - Recurrent UTI/pyelonephritis - Obstructive uropathy - NSAIDs/nephrotoxins | Primary: Minimal change disease (children), FSGS, membranous nephropathy, MPGN Secondary: Diabetes, SLE, amyloidosis, infections (HBV, HCV, malaria) | - Glomerular: IgA nephropathy, GN, Alport syndrome - Urologic: UTI, urolithiasis, bladder/renal cancer, trauma - Vascular: AV malformation - Medications: anticoagulants - Exercise-induced (transient) |
| Clinical Features / Symptoms | Cystitis: dysuria, frequency, urgency, suprapubic pain, cloudy/malodorous urine Pyelonephritis: fever, chills, flank pain, costovertebral angle (CVA) tenderness, nausea/vomiting | - Hematuria (gross "tea-colored" or microscopic) - Oliguria - Proteinuria / foamy urine - Hypertension (may cause headache) - Periorbital/peripheral edema - Nausea, fatigue, lethargy | - Fatigue, weakness - Nausea/vomiting, anorexia - Fluid retention, edema - Hypertension - Pruritus - Pallor (anemia) - Uremic symptoms (late): encephalopathy, pericarditis, bleeding | - Massive edema (pitting, anasarca, ascites, pleural effusions) - Foamy urine - Fatigue, dyspnea - Hypertension - Muehrcke's lines (nails) - Eruptive xanthomata (hyperlipidemia) | Gross: red/pink/"tea-colored" urine Microscopic: symptom-free, found on dipstick Associated features vary by cause (dysuria = UTI; flank pain = stones; painless = malignancy; hypertension/edema = GN) |
| Diagnosis | - Urinalysis: pyuria, bacteriuria, nitrites, leukocyte esterase - Urine culture & sensitivity (>10^5 CFU/mL) - CBC (leukocytosis in pyelonephritis) - Imaging (ultrasound/CT) for complicated UTI | - Urinalysis: hematuria, RBC casts, dysmorphic RBCs, proteinuria - Urine culture (to exclude UTI) - Serum creatinine, electrolytes, CBC - Complement levels (C3 decreased >90% in post-strep GN; normal in IgA) - ASOT, streptozyme - ANA, ANCA, anti-GBM for systemic GN - Renal biopsy (definitive) | - eGFR <60 mL/min persisting >3 months - Serum creatinine, BUN elevated - Urinalysis: proteinuria, casts - CBC: normocytic anemia - Metabolic panel: hyperkalemia, metabolic acidosis, hyperphosphatemia, hypocalcemia - Renal ultrasound (small, echogenic kidneys) - Staging by GFR (G1-G5) | - Proteinuria >3.5 g/day (or spot protein:creatinine ratio) - Serum albumin <2.5 g/dL - Hyperlipidemia (cholesterol >180 mg/dL) - Lipiduria (oval fat bodies, maltese cross on microscopy) - Serum creatinine (variable) - Renal biopsy (for cause) - Complement, ANA, HBsAg, HIV | - Urinalysis (dipstick + microscopy) - Urine culture - Urine cytology (if malignancy suspected) - Serum creatinine, complement, ASOT - Spot protein:creatinine ratio - Renal ultrasound, CT urogram - Cystoscopy (gross hematuria in adults >40 years) - Renal biopsy (if glomerular cause suspected) |
| Management | Uncomplicated cystitis: oral nitrofurantoin 5-7 days, or trimethoprim-sulfamethoxazole, or fosfomycin (single dose) Pyelonephritis: fluoroquinolone 7-14 days; IV ceftriaxone if hospitalized Complicated UTI: guided by culture; treat underlying structural cause | - Treat underlying cause (antibiotics for post-strep, steroids for lupus/IgA, immunosuppressants for ANCA) - ACE inhibitors/ARBs (reduce proteinuria) - Antihypertensives - Fluid/sodium restriction - Dialysis if rapidly progressive (AKI) - Renal biopsy guides specific therapy | - Treat underlying cause - BP control (ACE inhibitors/ARBs, target <130/80) - Glycemic control (diabetics) - Dietary protein restriction - Phosphate binders, vitamin D supplementation - Erythropoiesis-stimulating agents (anemia) - Diuretics (fluid overload) - Dialysis (GFR <10-15) or renal transplant (ESRD) | - Corticosteroids (first-line for minimal change disease) - Steroid-dependent/resistant: cyclosporine A, tacrolimus, mycophenolate, cyclophosphamide - ACE inhibitors/ARBs (antiproteinuric) - Diuretics (edema) - Statins (hyperlipidemia) - Anticoagulation if thrombosis risk high - Prophylactic antibiotics if recurrent infections | Treat underlying cause: - UTI: antibiotics - Stones: hydration, analgesia, urologic intervention - Malignancy: oncologic workup and treatment - GN: immunosuppression - IgA nephropathy: ACE inhibitors/ARBs - Gross hematuria with clot retention: bladder irrigation - Observation for isolated microscopic hematuria with no identifiable cause |
| Complications | - Pyelonephritis, urosepsis - Recurrent UTI - Renal scarring (children) - Perinephric abscess - Preterm labor (pregnancy) | - Hypertensive crisis - Nephrotic syndrome - Rapidly progressive GN (crescentic) - Acute kidney injury - Progression to CRF / ESRD | - Cardiovascular disease (leading cause of death) - Anemia - Renal osteodystrophy - Secondary hyperparathyroidism - Uremic pericarditis - Encephalopathy - ESRD requiring dialysis/transplant | - Deep vein thrombosis / renal vein thrombosis (loss of antithrombin, protein C & S) - Pulmonary embolism - Infections (cellulitis, peritonitis - due to low IgG, reduced complement) - Atherosclerosis (hyperlipidemia) - AKI - Malnutrition | - Renal scarring - AKI (if severe) - Anemia - Underlying malignancy progression - Recurrent episodes if cause untreated |
| Prevention | - Adequate hydration and frequent voiding - Wipe front to back (women) - Post-coital voiding - Avoid spermicides/diaphragms - Prophylactic low-dose antibiotics (recurrent UTI) - Cranberry products (evidence limited) - Catheter care bundles (CAUTI prevention) | - Treat streptococcal infections promptly - Early treatment of systemic diseases (lupus, vasculitis) - Antiretroviral therapy for viral-related GN - Regular monitoring in at-risk populations | - Control BP and blood sugar (diabetes) - Avoid nephrotoxins (NSAIDs, contrast agents, aminoglycosides) - Treat UTIs promptly - Regular eGFR monitoring in high-risk patients - Dietary counseling - Smoking cessation | - No specific prevention for primary forms - Secondary: treat underlying disease (diabetes control, lupus management) - Avoid nephrotoxic drugs - Regular urine screening in diabetic patients | - Adequate hydration (reduces stone formation) - Prompt treatment of UTIs - Smoking cessation (reduces bladder cancer risk) - Avoid prolonged catheterization - Regular surveillance in high-risk patients (prior malignancy) |
- UTI vs. GN: Both cause hematuria and pyuria, but RBC casts on urine microscopy define GN, not UTI - Tintinalli's Emergency Medicine
- Nephrotic vs. Nephritic: Nephrotic = massive proteinuria + edema + hypoalbuminemia (bland urine sediment); Nephritic = hematuria + RBC casts + hypertension (active sediment) - Frameworks for Internal Medicine
- Chronic Renal Failure: Irreversible; staged G1-G5 by eGFR. ESRD (G5) requires renal replacement therapy
- Hematuria red flags: painless gross hematuria in adult >40 years demands urgent cystoscopy to exclude malignancy - Campbell-Walsh Urology
- Glomerular hematuria: suggested by dysmorphic/crenated RBCs and RBC casts; brown "tea-colored" urine rather than bright red - Brenner & Rector's The Kidney
