REVERSE UNIFIED DIAGNOSTIC CRITERIA
⭐ Used for diagnosis of
⭐ Based on
🎯 ADPKD
🎯 USG: Kidney
REVERSE UNIFIED DIAGNOSTIC CRITERIA
If Adult with FAMILY H/O ADPKD does not develop CYSTS in Kidney (MRI) by 30 years, the
Will NOT DEVELOP ADPKD
⚡⚡ MOST COMMON AGE OF PRESENTATION of ADPKD
20-40 yrs
🧑🏻⚕️ Clinical Features of POLYCYSTIC KIDNEY DISEASE
- Hypertension
- Renomegaly ➡️ Abdominal discomfort
- Nocturia (DUE TO: Impaired CONCENTRATING Ability of Kidney)
- Anemia: Rare
60/60 rule in ADPKD
By 60 years of AGE, 60% patients will develop ESRD
Poor PROGNOSTIC FACTORS in ADPKD
- Black ♂️
- < 30 years
- Hematuria
- HTN at < 35 years age
- PKD1 TRUNCATING mutation
STRONGEST RISK FACTOR FOR RENAL FUNCTION DECLINE in ADPKD
Kidney Volume & Cyst Volume
(Diagnosed in MRI)
COMPLICATION of ADPKD
- Hypertension
✨ Target organ damage
✨ Biventricular Diastolic Dysfunction - CYST Rupture(rare) ➡️ PERITONITIS
- ABDOMINAL PAIN
✨ CYST infection
✨ CYST hemorrhage
✨ Stones (Uric acid > Calcium oxalate) - Necrotizing Pyomyositis
Indication of FDG-PET SCAN in ADPKD
Infections
Indication of CT-Urography SCAN in ADPKD
Stones
💊💉 MANAGEMENT of ADPKD
🧠⚡3C for Cyst infection ⚡
- Hypertension
⭐ ACE ⛔ (OR) ARBs - Cyst Infection
⭐ Carbapenams
⭐ Ciprofloxacin
⭐ Cotrimoxazole - Stones
⭐ Potassium Citrate - Hydration
⭐ > 4 liters/day
Target BP in ADPKD
SYSTOLIC: 95-110
DIASTOLIC: 60-75
Why HYDRATION is an IMPORTANT TREATMENT MANAGEMENT TOOL in ADPKD?
Cyst growth is dependent on ADH
