Nephrology Diseases covered at Saturn Medic span the full spectrum of kidney disorders tested in medical school, from common electrolyte disturbances to complex glomerular diseases, chronic kidney disease, and renal emergencies. Each case is built for exam-focused, high-yield learning, covering symptoms, causes, diagnosis, and treatment in a clear, structured format designed for medical students preparing for both coursework and clinical practice. Whether reviewing for exams or building a stronger clinical foundation, students will find each of these nephrology diseases broken down into the key facts most often tested, with an emphasis on distinguishing similar-sounding conditions from one another.

Nephrotic Syndrome, one of the most heavily tested nephrology diseases, includes Minimal Change Disease, Focal Segmental Glomerulosclerosis, and Membranous Nephropathy, all resulting from damage to the glomerular filtration barrier. Students learn to distinguish these conditions using biopsy findings, proteinuria severity, and age of onset.

Nephritic Syndrome and Glomerulonephritis, another major category of nephrology diseases, include Post-Streptococcal Glomerulonephritis, IgA Nephropathy, Rapidly Progressive (Crescentic) Glomerulonephritis, and Lupus Nephritis, exploring the immune-mediated mechanisms behind glomerular inflammation. This section emphasizes distinguishing infection-associated from autoimmune causes and interpreting complement levels and urinalysis findings.

Acute Kidney Injury, among the most clinically urgent nephrology diseases, covers Prerenal AKI, Acute Tubular Necrosis, Acute Interstitial Nephritis, and Postrenal AKI, all centered on sudden loss of kidney function. Key learning points include distinguishing prerenal, intrinsic, and postrenal causes using FeNa, urine microscopy, and BUN/creatinine ratios.

Chronic Kidney Disease and Nephropathies represent some of the most prevalent nephrology diseases worldwide, including Diabetic Nephropathy, Hypertensive Nephrosclerosis, Chronic Kidney Disease, and End-Stage Renal Disease, covering conditions of progressive, irreversible kidney damage and their shared cardiovascular risk implications.

Cystic and Congenital Kidney Diseases cover Autosomal Dominant Polycystic Kidney Disease, Autosomal Recessive Polycystic Kidney Disease, and Medullary Cystic Kidney Disease, completing the core genetic framework within these nephrology diseases. Students learn to distinguish these conditions by inheritance pattern, age of presentation, and associated extrarenal findings.

Tubular and Electrolyte Disorders, an often-overlooked group of nephrology diseases, include Renal Tubular Acidosis (Types 1, 2, and 4), Fanconi Syndrome, SIADH, and Diabetes Insipidus, focusing on tubular transport defects and water/electrolyte imbalance.

Nephrolithiasis and Obstructive Disorders, rounding out this category of nephrology diseases, cover Calcium, Uric Acid, Struvite, and Cystine Kidney Stones, along with Hydronephrosis and Urinary Tract Obstruction, distinguishing stone types by composition, risk factors, and imaging findings.

Renal Emergencies and Reactive Conditions, the most urgent of these nephrology diseases, cover Hyperkalemia, Contrast-Induced Nephropathy, and Hemolytic Uremic Syndrome, distinguishing true nephrologic emergencies from reversible, drug- or contrast-related kidney insults.
