Overview
- What this deck will teach you
Foundations
What MCDK is, and where it sits among cystic kidneys
- First, the big picture: cystic kidney diseases
- Defining the multicystic dysplastic kidney (MCDK)
- A short history: an old description that still holds
How Common and Who Gets It
What routine antenatal scanning revealed
- Why MCDK suddenly looks more common
- MCDK by the numbers
- Who gets it: sex and side
- Anomalies that travel with unilateral MCDK
Pathology and Pathogenesis
What it looks like, and why it forms
- Macroscopic appearance: what the surgeon sees
- Macroscopic multicystic dysplastic kidney
- Microscopic hallmark: what the pathologist sees
- Microscopic view of MCDK tissue
- Why it forms: the developmental short-circuit
- The genetic angle
Classification and Associations
Sorting MCDK into useful groups
- Two ways to classify MCDK
- Compensatory hypertrophy: the good-kidney safety net
- What else MCDK associates with
Presentation and Diagnosis
From incidental scan finding to confirmed diagnosis
- How MCDK shows up: then versus now
- Diagnostic evaluation: ultrasound leads
- Ultrasound features that suggest MCDK
- Ultrasound of a multicystic dysplastic kidney
- The main mimic, and how to tell them apart
- Functional imaging: DMSA and MAG3
Natural History
Involution, cancer risk and blood pressure
- Involution: the kidney that disappears
- Can we predict which ones involute?
- Malignant transformation: real risk or old fear?
- Hypertension: another poorly defined, low risk
Management
Why the pendulum swung to conservative care
- A paradigm shift over two decades
- Why we still follow these children up
- The VCUG debate
- Indications for nephrectomy (removing the MCDK)
