Renal: Renal Calculi: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Renal Calculi🎧 A high-yield breakdown of kidney stones – from causes to complications – tailored for exams and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Solid crystalline deposits formed in the kidneys or urinary tract, often due to supersaturation of urine with minerals.📌 Causes & Risk Factors• Dehydration• High dietary oxalate, sodium, animal protein• Hyperparathyroidism, gout, UTIs• Low urinary citrate• Family or personal history• Certain meds (diuretics, ARVs)💡 Mnemonic: “SICK KID” – Sepsis, IV contrast, CKD, K+ imbalance, Infection, Diet📌 Pathophysiology• Supersaturation → Precipitation → Aggregation → Stone formation• Promoted by ↓ urine volume, infection, altered pH, urinary stasis📌 Symptoms• Severe flank/loin pain (renal colic)• Hematuria (microscopic or visible)• Nausea, vomiting, dysuria, urgency• Pain radiating to groin or genitals• Fever/chills if infection present📌 Differential Diagnosis• UTI, pyelonephritis• Aortic dissection (esp. >60yrs)• Pancreatitis, torsion, diverticulitis• Malignancy, Munchausen’s📌 Diagnosis• Urinalysis: blood, nitrates, pH• Bloods: U+Es, creatinine, CRP, calcium, uric acid• Imaging: Non-contrast CT (first-line in adults)• Renal USS in pregnancy or children• Stone analysis post-passage💡 Encourage patients to strain urine to catch stones!📌 Management• Conservative: Hydration, analgesia (NSAIDs), antiemetics• Medical expulsive therapy (MET): Tamsulosin, nifedipine• Antibiotics if infection suspected• Procedures:ESWL (shockwave)UreteroscopyPCNL (for large/complex stones)Stents or open surgery in select cases• Emergencies:Bilateral obstructionObstructed infected kidney (pyelonephritis) → urgent urology• Admission if:AKI risk, infection signs, severe pain, anuria, delayed imaging📌 Complications• Obstruction, hydronephrosis• Recurrent UTIs• Irreversible kidney damage• Sepsis (life-threatening)• Rare: RCC/UTUC association, urinoma📌 Prognosis• Good if managed early• 95% passage for stones <4mm• 50% for 5–10mm• Recurrence: 50% at 5yrs, up to 80% at 10yrs🎯 Prevention is crucial🛡️ Prevention Tips• Drink 2–3L water daily• Add lemon juice (↑ citrate)• Avoid colas & ↓ salt intake• Maintain healthy diet & weight• Do NOT restrict calcium intake – may worsen oxalate stone risk• Use meds (e.g. allopurinol, potassium citrate) tailored to stone type📎 More MSRA Resources for Renal Calculi📝 Revision Notes: https://www.passthemsra.com/topic/renal-calculi-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/renal-calculi-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/renal-calculi-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/renal-calculi-rapid-quiz/🧪 Topic Quiz: https://www.passthemsra.com/quizzes/renal-calculi/🎓 Full Course: https://www.passthemsra.com/courses/renal-for-the-msra/Explore full revision guides, quizzes, flashcards, and more at👉 https://www.passthemsra.com#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #Renal #RenalCalculi
