1. High-Yield Flashcards
Tap each question to reveal the answer.
What three findings form the core nephrotic pattern?
Significant proteinuria, hypoalbuminemia and edema.
What urinary finding strongly supports a nephritic glomerular process?
Hematuria with red-cell casts.
Why does nephrotic syndrome cause edema?
Urinary protein loss causes hypoalbuminemia and reduced plasma oncotic pressure, with renal sodium retention further increasing edema.
Which disease is an important cause of typical childhood nephrotic syndrome?
Minimal change disease.
What treatment response supports typical childhood minimal change disease?
A good response to corticosteroid therapy.
What two major complications should be remembered in nephrotic syndrome?
Significant infection and thrombosis.
What clinical timing suggests post-streptococcal glomerulonephritis?
A nephritic syndrome developing after a latent interval following streptococcal throat or skin infection.
What complement pattern supports post-streptococcal glomerulonephritis?
Reduced complement, particularly low C3.
What timing of hematuria favors IgA nephropathy?
Hematuria occurring during or soon after an upper respiratory infection.
What complement pattern is generally expected in IgA nephropathy?
Complement is generally preserved.
What does a rising serum creatinine indicate in glomerular disease?
Reduced glomerular filtration and possible worsening renal dysfunction.
What ultrasound finding may support chronic renal parenchymal damage?
Small echogenic kidneys in the appropriate clinical context.
When is renal biopsy particularly useful in glomerular disease?
When diagnosis is uncertain or identifying the exact glomerular lesion would alter management.
Why must aggressive diuresis be used cautiously in nephrotic edema?
A patient may have reduced effective intravascular volume despite obvious tissue edema.
Which findings suggest progression of chronic glomerular disease?
Persistent proteinuria, hypertension and progressively worsening renal function.
2. Mnemonics
Mnemonic Title: Nephrotic Pattern
PEAL
Meaning: Proteinuria → Edema → low Albumin → increased Lipids.
Mnemonic Title: Nephritic Pattern
HOP
Meaning: Hematuria → Oliguria → high blood Pressure.
Mnemonic Title: Nephrotic Complication Alert
ITH
Meaning: Infection → Thrombosis → Hypovolemia.
3. Memory Tables
Nephrotic vs Nephritic Pattern
| Feature | Nephrotic | Nephritic |
|---|---|---|
| Main problem | Protein leakage | Inflammatory capillary injury |
| Dominant urine finding | Marked proteinuria | Hematuria / red-cell casts |
| Albumin | Reduced | Not the dominant feature |
| Blood pressure | May be normal or raised | Hypertension important |
| Example | Minimal change disease | PSGN / IgA nephropathy |
4. Rapid Revision Points — Last-Minute Revision
- Must Remember: Periorbital puffiness, especially in the morning, is an important clue to renal edema.
- Must Remember: Frothy urine suggests significant proteinuria.
- Must Remember: Red-cell casts strongly indicate a glomerular source of hematuria.
- Must Remember: Minimal change disease is an important childhood cause of nephrotic syndrome.
- Must Remember: Corticosteroids are central to treatment of typical childhood minimal change nephrotic syndrome.
- Must Remember: Low C3 after a latent interval following streptococcal infection supports PSGN.
- Must Remember: Hematuria during or soon after an upper respiratory infection favors IgA nephropathy.
- Must Remember: Severe hypertension, oliguria and respiratory distress are renal red flags.
- Must Remember: Small echogenic kidneys support chronic parenchymal damage in the correct clinical setting.
- Must Remember: Persistent proteinuria, hypertension and worsening renal function suggest progression toward chronic kidney disease.
KMU Trap: PSGN and IgA nephropathy can both present with glomerular hematuria. The key distinction is timing: PSGN follows infection after a latent interval, while IgA nephropathy commonly occurs during or soon after the respiratory infection.

6. Starred High-Yield Exam Points
- ⭐ Heavy proteinuria + hypoalbuminemia + edema = nephrotic pattern.
- ⭐ Hematuria + red-cell casts + hypertension = nephritic glomerular pattern.
- ⭐ Minimal change disease is a major cause of childhood nephrotic syndrome and typically responds to corticosteroids.
- ⭐ Low C3 with nephritic syndrome after a latent post-streptococcal interval supports PSGN.
- ⭐ Hematuria during or soon after respiratory infection with preserved complement favors IgA nephropathy.
- ⭐ Persistent proteinuria + hypertension + rising creatinine indicates progressive glomerular damage and risk of chronic kidney disease.
