🏥 MASTERING URINARY SYSTEM CLINICAL CASES

The Complete Urologist's Cheat Sheet — Diagnosis, Drugs & Doses

---

PART 1 - UTI SPECTRUM (Diagnosis Pathway + Drugs)

---

1A. UNCOMPLICATED CYSTITIS (Lower UTI)

Symptoms (dysuria + frequency) → Dipstick urinalysis
  ↓
Nitrites (+) or Leukocyte esterase (+) → Treat empirically
  ↓
Urine culture (only if recurrent, treatment failure, or pregnancy)
  ↓
Threshold: ≥10² CFU/mL if symptomatic + pyuria (NOT ≥10⁵ for cystitis)

---

1B. ACUTE PYELONEPHRITIS (Upper UTI)

Fever + flank pain + CVA tenderness → Urine dipstick + culture (MANDATORY)
  ↓
Urine culture: ≥10⁵ CFU/mL + pyuria → Diagnosis confirmed
  ↓
Blood cultures if sepsis signs (T >38.5, HR >100, RR >20)
  ↓
CBC, CMP, CRP
  ↓
Renal ultrasound (to rule out obstruction, abscess, stone)
  CT abdomen with contrast if US inconclusive or not improving in 72 hrs

---

1C. COMPLICATED UTI (cUTI)

---

1D. CATHETER-ASSOCIATED UTI (CAUTI)

1. Remove or replace catheter first
2. Urine culture from new catheter
3. Treat 7 days (shorter if prompt clinical response)
4. Same drugs as complicated UTI

---

1E. RECURRENT UTI

• Relapse = same organism within 2 weeks (inadequate treatment)
• Reinfection = different organism or >2 weeks later

---

PART 2 - KIDNEY STONES (Urolithiasis)

---

2A. DIAGNOSIS PATHWAY

Severe flank pain → CTKUB (Non-contrast CT KUB) ← GOLD STANDARD
  ↓
Also: Urinalysis (hematuria in 85%), urine pH
  ↓
Serum: Creatinine, calcium, uric acid, phosphate, bicarbonate
  ↓
Stone passed → STONE ANALYSIS (XRD or infrared spectroscopy)
  ↓
First stone: Basic metabolic workup
Recurrent stone: 24-hour urine × 2 (calcium, oxalate, citrate, uric acid, pH, volume)

• CT KUB = best sensitivity/specificity (>95%/98%), detects all stone types
• Ultrasound = first-line in pregnancy, children, radiation concern; misses ureteral stones
• KUB X-ray = only detects calcium stones (70%); useful for follow-up

---

2B. MANAGEMENT BY STONE SIZE

• Stones ≤4 mm: 80% pass spontaneously - analgesia + hydration
• Stones 5-7 mm: 50-60% pass - MET (medical expulsive therapy)
• Stones >10 mm: Unlikely to pass - intervention needed

---

2C. STONE PREVENTION (Metabolic Treatment)

---

2D. SURGICAL OPTIONS (AUA 2026)

---

PART 3 - BENIGN PROSTATIC HYPERPLASIA (BPH)

---

3A. DIAGNOSIS PATHWAY

History + IPSS Score → IPSS 0-7 mild | 8-19 moderate | 20-35 severe
  ↓
DRE (enlarged, smooth, rubbery prostate)
  ↓
Urinalysis (rule out UTI, hematuria)
  ↓
PSA (if >50 yrs, or if cancer changes management)
  ↓
Post-void residual (PVR) by US - >100 mL significant
  ↓
Uroflowmetry: Qmax < 10 mL/s = BOO, 10-15 borderline, >15 normal
  ↓
TRUS (transrectal ultrasound) if surgery planned - measure prostate volume

---

3B. MEDICAL TREATMENT (BPH Drugs)

• Alpha blocker + 5-ARI (e.g., tamsulosin + dutasteride = "Combodart 0.5/0.4 mg") - reduces progression, retention, need for surgery (MTOPS, CombAT trials)
• Alpha blocker + tadalafil - LUTS + ED
• Alpha blocker + mirabegron - voiding + storage symptoms

---

3C. SURGICAL OPTIONS (BPH)

---

PART 4 - ACUTE KIDNEY INJURY (AKI)

---

4A. DIAGNOSIS PATHWAY

Elevated creatinine → Rule out CKD (check baseline Cr)
  ↓
Classify: PRE-RENAL vs INTRINSIC vs POST-RENAL
  ↓
FeNa (Fractional excretion of sodium):
  FeNa = (UNa × PCr)/(PNa × UCr) × 100
  <1% = Pre-renal | >2% = Intrinsic | Varies in obstruction
  ↓
FeUrea <35% = Pre-renal (useful if on diuretics)
  ↓
Urine microscopy: RBC casts = GN | Granular "muddy brown" casts = ATN | WBC casts = Pyelonephritis/interstitial
  ↓
Renal ultrasound: Hydronephrosis = post-renal obstruction

• Pre-renal: Dehydration, hemorrhage, sepsis, heart failure, NSAIDs, ACEi/ARB (in bilateral RAS)
• Intrinsic renal: ATN (most common - ischemia or nephrotoxins), GN, AIN, contrast nephropathy
• Post-renal: BPH, stones, tumor, stricture (catheter fixes this instantly)

---

4B. MANAGEMENT

• Acidosis (pH <7.1)
• Electrolytes (K >6.5 or refractory)
• Ingestion (toxins)
• Overload (volume unresponsive to diuretics)
• Uremia (uremic pericarditis, encephalopathy, platelets dysfunction)

---

PART 5 - GLOMERULAR DISEASES (Nephrology Side)

---

5A. NEPHROTIC vs NEPHRITIC SYNDROME - KEY DIFFERENTIATOR

---

5B. NEPHROTIC SYNDROME

• Edema: Furosemide 40-120 mg/day + dietary Na restriction <2 g/day
• Proteinuria reduction: ACEi (Enalapril/Ramipril) or ARB (Losartan/Irbesartan) - reduce GFR-related proteinuria
• Dyslipidemia: Statin (Atorvastatin 10-40 mg/day)
• Thrombosis prophylaxis: Anticoagulation if albumin <2.5 g/dL, especially membranous nephropathy

---

5C. NEPHRITIC SYNDROME

---

PART 6 - PROSTATE CANCER

---

6A. DIAGNOSIS PATHWAY

PSA screening (≥50 yrs; ≥40 yrs if high risk)
  ↓
PSA >4 ng/mL → TRUS/MRI (multiparametric MRI preferred)
  ↓
PI-RADS score on mpMRI: ≥3 → systematic + targeted biopsy
  ↓
TRUS-guided biopsy OR MRI-US fusion biopsy (preferred)
  ↓
Gleason score / ISUP grade group
  ↓
Staging: CT chest/abdomen/pelvis + bone scan
    (PSMA-PET scan preferred if locally advanced)

• Low risk: PSA <10, Gleason ≤6 (ISUP 1), T1-T2a
• Intermediate: PSA 10-20 OR Gleason 7 (ISUP 2-3) OR T2b-c
• High risk: PSA >20 OR Gleason 8-10 (ISUP 4-5) OR T3-T4

---

6B. TREATMENT (Prostate Cancer)

---

PART 7 - BLADDER CANCER

---

7A. DIAGNOSIS PATHWAY

Painless hematuria → CT urogram (GOLD STANDARD for upper tract)
  ↓
Urine cytology (high grade, CIS detection)
  ↓
CYSTOSCOPY (mandatory) + biopsy ← Definitive diagnosis
  ↓
TURBT (transurethral resection) - diagnostic AND therapeutic
  ↓
Pathology: depth of invasion → Ta, T1, CIS (NMIBC) vs T2+ (MIBC)

---

7B. TREATMENT

• Neoadjuvant cisplatin-based chemo (MVAC or GC) + radical cystectomy (gold standard)
• Or concurrent chemoradiation (bladder preservation)

---

PART 8 - OVERACTIVE BLADDER (OAB)

---

8A. DIAGNOSIS

OAB symptoms → Urinalysis (rule out UTI)
  ↓
Voiding diary (3-day frequency/volume chart)
  ↓
Post-void residual (rule out BOO/retention)
  ↓
Urodynamics if diagnosis uncertain or failed initial treatment

---

8B. TREATMENT (Stepwise)

• Bladder training (gradually increase voiding intervals)
• Fluid management (reduce caffeine, alcohol; 1.5-2L/day fluid)
• Pelvic floor exercises

• Botulinum toxin A (Botox) - 100 units intravesical injection (cystoscopy); repeat Q6-12 months
• Percutaneous tibial nerve stimulation (PTNS) - weekly × 12 sessions, then monthly
• Sacral neuromodulation (InterStim) - implanted device

---

PART 9 - URINARY INCONTINENCE

---

9A. TYPES AND DRUG TREATMENT

---

PART 10 - HEMATURIA EVALUATION

---

10A. HEMATURIA PATHWAY

Hematuria
  ↓
Dysmorphic RBCs, RBC casts, proteinuria → GLOMERULAR (nephrology)
  ↓
Isomorphic RBCs, no casts, no/minimal proteinuria → UROLOGICAL
  ↓
CT urogram → Cystoscopy → Consider urine cytology

2025 ACC/AHA ACS Guidelines - KEY UPDATES

Chest pain → ECG within 10 minutes (first medical contact)
  ↓
STEMI (ST elevation ≥1mm in ≥2 contiguous leads, or LBBB):
  → Primary PCI within 90 min (door-to-balloon)
  → Fibrinolysis if PCI unavailable AND <12h onset

NSTE-ACS (NSTEMI/UA) → hs-cTn at 0h + 1h (or 0h + 2h)
  → Risk stratify: GRACE score OR TIMI score
  → High risk: invasive strategy within 2-24h
  → Low risk: can discharge with outpatient workup

• DAPT duration: 1-3 months then drop aspirin + continue ticagrelor (TWILIGHT strategy, Class I)
• Patient on OAC + ACS: Triple therapy 1-4 weeks → OAC + P2Y12 (drop aspirin)
• Prasugrel now generic - cost similar to clopidogrel; viable alternative
• hs-cTn 0h/1h rule-out algorithm standard of care

• Posterior MI: ST depression in V1-V3 → do posterior leads
• de Winter T-waves: LAD occlusion without ST elevation → treat as STEMI
• Wellens syndrome: T-wave changes in V2-V3 → LAD critical stenosis → CATH URGENTLY

---

1.4 ATRIAL FIBRILLATION

Diagnosis + Management Framework

New onset AF:
1. Rate control vs Rhythm control decision
2. CHA₂DS₂-VASc score → anticoagulation decision
3. HAS-BLED score → bleeding risk assessment

GRAND CHEAT CODE SUMMARY

CARDIOLOGY CODES:
● HFrEF = 4 pillars: ARNI + BB + MRA + SGLT2i (think "A Beautiful Marriage Saves")
● STEMI = primary PCI within 90 min; fibrinolysis if PCI >120 min
● ACS DAPT 2025: 1-3 months DAPT then drop ASA, keep P2Y12 (TWILIGHT)
● AF + OAC + ACS: triple → dual (drop ASA, keep OAC + P2Y12) after 4 weeks
● BP target 2025: <130/80 ALL patients; PREVENT calculator (not PCE)
● Resistant HTN: Add spironolactone (PATHWAY-2 trial)

ENDOCRINOLOGY CODES:
● T2DM + CVD: SGLT2i or GLP-1RA always (not just HbA1c control)
● T2DM + HF/CKD: SGLT2i first
● DKA: K+ first - if K+ <3.3, HOLD insulin, replace K+ first
● Thyroid storm: Block synthesis (PTU) → block release (iodine, wait 1h) → block conversion (propranolol) → block peripheral effects

PULMONOLOGY CODES:
● Asthma 2024: ICS-formoterol as RELIEVER (SMART therapy) - NOT SABA alone
● COPD O2: Target SpO2 88-92% (NOT high flow - CO2 retention)
● PE massive: Alteplase 100 mg IV over 2h
● COPD steroids: Prednisolone 40 mg × 5 days = 14 days (REDUCE trial)

GI CODES:
● H. pylori: Bismuth quadruple × 14 days preferred in areas with high clarithromycin resistance
● Confirm eradication: Urea breath test ≥4 weeks after antibiotics (not serology)
● UC severe: IV hydrocortisone → if no response day 3 → infliximab or cyclosporine

INFECTIOUS DISEASE CODES:
● Sepsis 1h bundle: Cultures → Antibiotics → Fluids → Vasopressors
● Empiric MRSA coverage: Vancomycin IV (AUC-guided) or Linezolid (pneumonia)
● NEVER use daptomycin for pneumonia (lung surfactant inactivates it)
● TB 2-HRZE/4HR rule: Pyridoxine with INH; Ethambutol = check eyes

HEMATOLOGY CODES:
● B12 deficiency: ALWAYS replace B12 before folate (folate masks neuro worsening)
● Dabigatran reversal: Idarucizumab (Praxbind)
● Heparin reversal: Protamine 1 mg per 100 units UFH
● Factor Xa reversal: Andexanet alfa (expensive); 4-factor PCC alternative

NEUROLOGY CODES:
● Ischemic stroke: IV tPA within 4.5h; thrombectomy up to 24h (select patients)
● Status epilepticus: Benzo → Levetiracetam/Valproate IV → Propofol/Midazolam ICU
● TIA + minor stroke: DAPT (ASA + Clopidogrel) × 21 days ONLY (POINT/CHANCE)

EMERGENCY CODES:
● Anaphylaxis: EPINEPHRINE IM FIRST - everything else second
● Hyperkalemia >6.5: Calcium IV first (membrane stabilization), then insulin+glucose
● Succinylcholine CI: Hyperkalemia, burns >24h, crush injury >72h, denervation injury
● RSI in asthma/shock: Use Ketamine (bronchodilator + vasopressor preserving)

---

NEET PG PATHOLOGY WEIGHTAGE (10-Year PYQ Analysis)

---

PART 1 - GENERAL PATHOLOGY (30% Weightage)

---

CHAPTER 1: CELL INJURY

The Big Picture (From Robbins Basic Pathology)

---

Reversible vs Irreversible Injury

1. Cellular swelling (= hydropic change / vacuolar degeneration) - most common
2. Fatty change (lipid vacuoles in cytoplasm - mainly liver)
3. Increased eosinophilia of cytoplasm
4. Surface blebs on plasma membrane
5. ER dilation, ribosome detachment

• Swelling (cellular)
• Fatty change
• Eosinophilia (increased)

---

NECROSIS - Types (NEET PG Highest Yield)

• Coagulative
• Liquefactive
• Fat (enzymatic/traumatic)
• Fibrinoid
• Special = Caseous
• Gangrenous
• Atypical = Wet gangrene
• Neuronal (special)

Necrosis Type Comparison Table (MOST ASKED)

Q: Brain infarction → LIQUEFACTIVE (not coagulative) - Brain is exception!
Q: TB node → CASEOUS necrosis
Q: Acute pancreatitis → FAT necrosis (enzymatic; lipase)
Q: Fibrinoid necrosis seen in → malignant HTN, polyarteritis nodosa, SLE vessels
Q: Coagulative is the most common type of necrosis overall
Q: "Ghost outline of cells" = Coagulative necrosis
Q: "No architecture preserved" = Caseous necrosis
Q: Chalky white deposits in fat = Ca soaps = Fat necrosis

---

Nuclear Changes in Necrosis (NEET PG Classic)

• Pyknosis → nuclear condensation (shrinkage, dark)
• Karyorrhexis → nuclear fragmentation
• Karyolysis → nuclear dissolution (fade away)

---

APOPTOSIS vs NECROSIS (Tabular - Very High Yield)

• Bcl-2 = Anti-apoptotic (pro-survival; overexpressed in follicular lymphoma)
• Bax, Bak = Pro-apoptotic
• Cytochrome C = Released from mitochondria → activates caspases
• Caspases = Executioners of apoptosis (cysteine proteases)
• p53 = Guardian of genome → induces apoptosis when DNA damaged
• Fas-FasL = Extrinsic pathway (receptor-ligand)

NEET PG Tip: Bcl-2 overexpression → follicular lymphoma (t(14;18))
NEET PG Tip: Cytochrome C + Apaf-1 → apoptosome → activates caspase-9 (intrinsic)
NEET PG Tip: TNF + Fas → caspase-8 activation (extrinsic pathway)

---

FREE RADICAL INJURY (High Yield)

• Reperfusion after ischemia (most important clinically)
• Radiation
• Drugs/chemicals (CCl4 → liver)
• Normal cellular respiration (mitochondrial leakage)

• ROS = Reactive Oxygen Species
  • Superoxide (O2-) → most common
  • Hydrogen peroxide (H2O2)
  • Hydroxyl radical (•OH) → most toxic/reactive
• Nitric oxide (NO•)

• Superoxide dismutase (SOD) → converts O2- to H2O2
• Catalase → breaks H2O2 → H2O + O2
• Glutathione peroxidase → uses GSH to neutralize H2O2
• Vitamin E (tocopherol) → lipid antioxidant
• Vitamin C (ascorbic acid) → aqueous antioxidant
• Ceruloplasmin, transferrin → bind free iron (prevent Fenton reaction)

Mnemonic for antioxidants: "SoCAGE"

CHAPTER 2: INFLAMMATION

Acute Inflammation - Cardinal Signs

• Pain (Dolor)
• Redness (Rubor) - vasodilation
• Induration/swelling (Tumor)
• Swelling (Tumor) - edema
• Heat (Calor) - vasodilation

---

Vascular Events in Acute Inflammation

1. Transient vasoconstriction (seconds)
2. Vasodilation (histamine, PGE2, PGI2, NO)
3. Increased vascular permeability → edema
4. Slowing of blood flow (stasis)
5. Leukocyte margination → rolling → adhesion → transmigration → chemotaxis

• Histamine (mast cells) = immediate, transient
• Bradykinin = immediate, sustained
• Leukotrienes (LTC4, LTD4, LTE4) = slow, sustained
• PAF (platelet activating factor)
• Substance P

---

Chemical Mediators of Inflammation (MASTER TABLE - Very High Yield)

Leukocyte Recruitment (Step-by-Step)

1. Selectin-mediated rolling
   • E-selectin + P-selectin on endothelium
   • L-selectin on leukocytes
   • Ligand: sialyl-Lewis X
2. Molecule upregulation (TNF, IL-1 activate endothelium)
3. Adhesion (firm) - Integrins
   • LFA-1 (CD11a/CD18) + ICAM-1
   • Mac-1 (CD11b/CD18) + ICAM-1
   • VLA-4 + VCAM-1
4. Roll → Activate → Adhere firmly
5. Transmigration (diapedesis) through vessel wall
   • PECAM-1 (CD31) - helps crossing
6. PMN chemotaxis to site
   • Chemokines, C5a, LTB4, bacterial peptides (fMLP)

NEET PG TRAP: LAD (Leukocyte Adhesion Deficiency) = Defect in CD18 (integrin β2)
→ No firm adhesion → no transmigration → recurrent bacterial infections
→ Delayed umbilical cord separation
→ NO PUS (neutrophils cannot reach tissue!)

---

WOUND HEALING

Primary vs Secondary Intention

1. Hemostasis (0-24h): Platelet plug + clot (fibrin matrix)
2. Inflammation (1-3 days): Neutrophils → Macrophages (Day 2-3)
3. Proliferation (3-14 days):
   • Angiogenesis (VEGF, FGF)
   • Fibroblast proliferation → collagen synthesis
   • Epithelialization
4. Remodeling (weeks-months): Collagen remodeling (type III → type I)

• Day 1-2: Neutrophils predominate
• Day 3-5: Macrophages predominate (most important cell in healing)
• Day 5-14: Fibroblasts → collagen
• Tensile strength: maximum by 3 months (80% of original)
• VEGF = most important for angiogenesis
• TGF-β = most important for fibrosis/scar
• Collagen type III = first deposited (young scar); replaced by type I later

Mnemonic: "Neat Macrophages Fix wounds"
N = Neutrophils (Day 1-2)
M = Macrophages (Day 3+) - most important
F = Fibroblasts (proliferative phase)
