Lesson 1Relevant renal and urinary tract anatomy: kidney, collecting system, ureteral course, relations causing referred painKidney and tube parts for stones: cups, basin, tube bends, blood/vessel ties, pain send to side, private area.
Renal cortex, medulla, and collecting systemRenal pelvis and calyceal anatomyUreteral course and narrow segmentsRelations to vessels, bowel, and pelvisPathways of referred flank and groin painLesson 2History elements: onset, prior stones, metabolic history, family history, medication/occupation risk factorsKey story for stone doubt: pain start, past stones, body salt ills, kin history, food, drugs, work risks for trouble or repeat.
Character and timing of pain episodesPast stones, procedures, and outcomesMetabolic and systemic disease historyFamily history and genetic conditionsDiet, fluid intake, drugs, occupationLesson 3Physical exam maneuvers: costovertebral angle tenderness, abdominal exam, testicular/inguinal exam when indicatedTarget body check for side pain: signs, belly, back angle press, private/groin if needed, signs other ills.
Vital signs and overall illness severityCostovertebral angle tenderness techniqueAbdominal exam for peritonitis or massGenital and inguinal exam when neededSigns pointing away from stone diseaseLesson 4Stone prevention basics: metabolic workup indications, 24-hour urine testing, dietary and pharmacologic prevention strategiesStone stop starts: when full body check, day urine test, food tips, drink aims, drugs fit stone kind, person risk.
Who needs full metabolic workupCollecting and interpreting 24‑hour urineFluid intake and urine volume targetsDietary sodium, protein, and oxalate advicePharmacologic prevention by stone typeLesson 5Acute management: analgesia ladder (NSAIDs vs opioids), antiemetics, medical expulsive therapy evidence and limitsFirst aid kidney pain: pain ease steps (swell stop vs strong), sick stop, fluids, push-out drug proofs/limits, watch vs admit rules.
Analgesia ladder and NSAID first strategyOpioid indications and safety concernsAntiemetics and fluid managementMedical expulsive therapy evidenceDisposition, follow‑up, and return precautionsLesson 6Evidence sources: major guidelines and reviews for suspected kidney stones (names and years to search)Main guides/reviews on kidney stones doubt, groups, years, search/appraise for test/treat choices.
Major urology and nephrology guidelinesEmergency medicine stone care guidelinesHigh‑impact systematic reviews and yearsSearching PubMed and guideline portalsAppraising guideline strength and gapsLesson 7Initial diagnostics: urinalysis for hematuria/infection, urine microscopy, serum electrolytes, renal function, inflammatory markersFirst labs for stone doubt: urine blood/germ, scope look, salts, kidney work, swell marks; read for diagnosis/risk.
Urinalysis for hematuria and infectionUrine microscopy for crystals and castsSerum creatinine and estimated GFRElectrolytes, calcium, and uric acidInflammatory markers and sepsis cluesLesson 8Indications for emergent urology referral: obstruction with infection, refractory pain, impaired renal function, anuriaUrgent specialist call: blocked germ system, pain/vomit no stop, one kidney fail, no urine, baby/kid notes.
Obstruction with sepsis or high feverRefractory pain or intractable vomitingAcute kidney injury and solitary kidneyAnuria, bilateral obstruction, pregnancyPediatric and complex comorbidity casesLesson 9Imaging strategy: when to use non-contrast CT KUB, ultrasound in pregnancy, plain radiography limitations, contrast indicationsScan plans for stones: no dye CT belly, sound for baby/young, xray limits, dye when trouble.
Non‑contrast CT KUB indicationsUltrasound in pregnancy and youthStrengths and limits of plain radiographyWhen to use contrast CT or urographyRadiation exposure and dose reductionLesson 10Stone pathophysiology and types: calcium, uric acid, struvite, cystine — formation mechanisms and metabolic risk factorsStone builds/types: lime, acid, germ, rare; seed start, over salt urine, germ ways, body/site risks.
Calcium oxalate and calcium phosphate stonesUric acid stone formation mechanismsStruvite stones and urease‑producing bacteriaCystine stones and inherited disordersMetabolic, urinary, and anatomic risk factorsLesson 11Typical clinical presentation: colic characteristics, hematuria, nausea/vomiting, pain radiation to groin/scrotum/labiaClassic kidney grip pain: feel, time, spread private, urine blood, sick/upset; differ flags for other dangers.
Pain onset, severity, and colicky patternRadiation to flank, groin, and genitaliaHematuria and lower urinary symptomsNausea, vomiting, and autonomic signsRed flags for alternative diagnoses
