🎧 FREE MSRA PODCAST – Renal Cell Carcinoma (RCC): Rapid-Recall Revision

Kidney cancer, demystified! We unpack RCC in the format you need: fast, focused, and full of clinical must-knows. Perfect for MSRA, UK practice, and beyond.

🧠 Key Learning Points

Definition
• Renal Cell Carcinoma (RCC) = Most common kidney cancer in adults
• Originates from the proximal renal tubule cells (lining the nephron)

Epidemiology
• 80% of kidney cancers are RCC
• Peak age: 60–70 years, more common in men
• Over 4,000 cases per year in the UK
• Rising incidence, higher in deprived areas, lower in Asian/Black groups

Risk Factors
• Smoking, obesity, hypertension
• Genetics: von Hippel-Lindau (VHL), tuberous sclerosis
• Chronic kidney disease, renal transplant
• Male sex, older age

Clinical Features
• Classic triad (rare!): haematuria, flank pain, abdominal mass
• Most common presentation: asymptomatic, found incidentally on scans
• Other: fatigue, weight loss, fever, varicocele, leg swelling, signs of metastasis (lungs, bones)
• Paraneoplastic syndromes: polycythaemia, hypercalcaemia

Diagnosis & Staging
• Imaging: Abdominal CT (main), ultrasound, MRI as indicated
• Bloods: Renal function, anaemia, calcium
• Biopsy: If diagnosis uncertain or for metastatic/active surveillance cases
• Staging: TNM system (Tumour, Node, Metastasis)
 – Stage 1–2 = localised
 – Stage 3 = local spread
 – Stage 4 = distant spread

Management
• Surgery: Partial or radical nephrectomy for localised tumours
• Ablation or surveillance: For select small tumours
• Advanced/metastatic disease:
 – Immunotherapy (e.g., nivolumab, ipilimumab)
 – Targeted therapy: TKIs (sunitinib, pazopanib), everolimus
 – Bisphosphonates for bone metastases
 – Radiotherapy: For isolated mets or palliation
• Chemotherapy: Not usually effective
• Long-term follow-up is crucial

Complications
• Metastases: Lungs, bones, liver
• Local invasion: Pain, kidney impairment
• Paraneoplastic syndromes
• Prognosis: Heavily stage-dependent
 – 1-year survival: ~79%
 – 5-year: ~64%
 – 10-year: ~52% (UK data)
• Best outcomes with early-stage diagnosis

Memory Aid:
“RCC = Renal Cancer Caught incidentally!”
Think: “Triad is rare—most are silent.”
TNM = The Next Move (for treatment)!

⚕️ 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)

• Ureteroscopy

• PCNL (for large/complex stones)

• Stents or open surgery in select cases
  • Emergencies:

• Bilateral obstruction

• Obstructed 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

⚕️ FREE MSRA PODCAST – Renal Artery Stenosis
🎧 A clear, high-yield breakdown of this vascular cause of secondary hypertension and kidney damage – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Narrowing (stenosis) of one or both renal arteries, reducing blood flow to the kidneys and activating the RAAS system – a major cause of secondary hypertension.

📌 Causes & Risk Factors
• Atherosclerosis – most common cause (≈90%) in older patients
• Fibromuscular dysplasia (FMD) – younger women, non-atherosclerotic
• Other causes: vasculitis, trauma, dissection, neurofibromatosis, aneurysms
🧠 Mnemonic: “A for Age, F for Female” – Atherosclerosis = older, FMD = younger female

📌 Pathophysiology
• ↓ Renal blood flow → perceived low pressure → ↑ renin
• Activates RAAS → vasoconstriction (via angiotensin II) + salt & water retention (via aldosterone)
• Result: Hypertension, often resistant to treatment
• Chronic ischaemia → progressive kidney damage

📌 Symptoms
• Resistant hypertension despite ≥3 antihypertensives
• Declining renal function
• Abdominal bruit on auscultation
• Possible oedema due to aldosterone-driven fluid retention
• Often asymptomatic until advanced
🧠 Key clue: Refractory hypertension with deteriorating renal function

📌 Differential Diagnosis
• Primary (essential) hypertension
• Chronic kidney disease
• Primary hyperaldosteronism
• Other renovascular conditions (e.g. aneurysm, dissection)

📌 Diagnosis
• Blood tests:
– U&Es (creatinine, potassium)
– Lipid profile
– Aldosterone:Renin ratio
• Imaging:
– 1st line: Duplex ultrasound (Doppler)
– 2nd line: CT angiography (CTA) or MR angiography (MRA)
– Gold standard: Renal arteriography (invasive, used for confirmation/intervention)
🧠 Tip: Ultrasound for screening, angiography for definitive diagnosis & treatment planning

📌 Management
• Lifestyle: Smoking cessation, low-salt diet, weight loss
• Medication:
– ACEi/ARBs (use with caution if bilateral or severe stenosis)
– Diuretics
– Statins + antiplatelets (e.g. aspirin) to reduce CV risk
• Revascularisation:
– Angioplasty ± stenting (PTA)
– Surgical options in select cases
🧠 Caution: ACEi/ARBs can worsen renal function in bilateral stenosis – monitor closely!

📌 Complications
• Uncontrolled hypertension → stroke, MI, heart failure
• Progressive CKD, possibly leading to end-stage renal disease (ESRD)
• Pulmonary oedema, flash pulmonary oedema
• Medication side effects (especially ACEi/ARB risks)

📌 Prognosis
• Depends on cause, severity, and comorbidities
• FMD generally better outlook than advanced atherosclerosis
• Early detection + control of BP and risk factors significantly improves outcomes

⚕️ FREE MSRA PODCAST – Prostatitis
🎧 A clear, high-yield breakdown of this common but complex prostate condition – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Prostatitis is inflammation of the prostate gland.
• It may be acute or chronic, and bacterial or non-bacterial.
• Chronic pelvic pain syndrome (CPPS) accounts for over 90% of cases.

📌 Causes & Risk Factors
• Acute bacterial: E. coli (most common), other gram-negative bacteria
• STIs: Chlamydia, Gonorrhoea
• Non-bacterial: pelvic floor dysfunction, psychological stress
• Risk factors: history of UTIs, BPH, catheterisation, recent instrumentation, age, sexual activity
🧠 Mnemonic: “BE CUPS” – BPH, E. coli, Catheter, UTIs, Procedures, Sex

📌 Pathophysiology
• Acute: ascending infection from urethra
• Chronic bacterial: persistent/hidden infection (e.g., in stones)
• CPPS: unclear – involves inflammation, neuromuscular dysfunction, stress
• Asymptomatic inflammatory: inflammation without symptoms

📌 Symptoms
• Pelvic/perineal pain
• Dysuria, frequency, urgency
• Painful ejaculation, sexual dysfunction
• Fever/chills (in acute)
• Chronic cases: fluctuating symptoms, psychological impact
🧠 Mnemonic: “Pee FEVER” – Pain, Ejaculation pain, Frequency, Erectile issues, Void urgency, Emotional distress, Recurring discomfort

📌 Differential Diagnosis
• Cystitis
• BPH
• UTI or bladder stones
• Bladder/prostate cancer
• Prostatic abscess
• Enterovesical fistula

📌 Diagnosis
• DRE: acute = hot, boggy, tender prostate
• Urine dip + culture
• STI screening if indicated
• PSA test
• Chronic cases: cystoscopy, urodynamics
• CPC-PPS: symptoms >3 months, negative cultures
• NIH Chronic Prostatitis Symptom Index (CPSI) for assessment

📌 Management
• Acute: admit if severe → IV antibiotics, fluids, pain relief
• Suprapubic catheter if retention
• Chronic bacterial: long-course antibiotics (e.g., doxycycline, trimethoprim), refer to urology
• CPC-PPS:
 – Analgesia (NSAIDs, paracetamol)
 – Avoid repeated antibiotics
 – Alpha-blockers
 – Multidisciplinary care: pain team, pelvic floor physio, psychological support
 – Neuromodulators (e.g. pregabalin)

📌 Complications
• Recurrent infections
• Prostatic abscess
• Urinary retention
• Sexual dysfunction
• Chronic pain → reduced quality of life
• Sepsis (in acute)

📌 Prognosis
• Acute: good if promptly treated
• Chronic: variable, often relapsing-remitting
• CPPS may need long-term, tailored care
🧠 Key stat: Over 90% of prostatitis cases are non-bacterial CPPS

✅ MSRA Deep Dive: Post-streptococcal Glomerulonephritis (PSGN)
In this high-yield episode, we take a clear, focused look at Post-streptococcal Glomerulonephritis (PSGN) — an immune-mediated renal condition that often follows strep throat or skin infections. Whether you’re prepping for the MSRA or strengthening your paediatric renal knowledge, this episode breaks down the key facts, diagnostic clues, and management pearls to help you revise smarter and remember better.

🧠 Key Learning Points

📌 Definition
• PSGN = Immune-mediated inflammation of the glomeruli following a recent Group A beta-haemolytic streptococcal infection
• Triggered by immune complex deposition rather than direct bacterial damage

📌 Pathophysiology
• Antibodies form against streptococcal antigens → immune complexes
• These complexes deposit in the glomeruli, activating complement → inflammation
• Leads to impaired filtration and renal dysfunction
• Low C3 levels = clue for complement consumption
• ASO titre or anti-DNase B confirms recent strep exposure

📌 Epidemiology & Risk Factors
• Primarily affects children aged 6–10
• More common in developing countries, areas of poor hygiene or crowded housing
• Recent strep pharyngitis or impetigo is key
• Adults with comorbidities = higher risk of complications

📌 Clinical Features
• Haematuria – dark, cola- or tea-coloured urine
• Oedema – periorbital or peripheral
• Hypertension – common in early presentation
• Oliguria, proteinuria, and systemic signs like fatigue, abdominal/flank pain, headache
• May be asymptomatic in mild cases, found on urine dipstick

📌 Diagnosis
• Urinalysis: haematuria + proteinuria
• Bloods: elevated urea/creatinine, low C3, high ASO/anti-DNase B titres
• BP monitoring: often hypertensive
• Renal biopsy: not usually needed unless atypical/severe – shows diffuse proliferative glomerulonephritis with granular IgG and C3 deposits

📌 Differential Diagnoses
• IgA nephropathy – haematuria closer to infection, normal C3
• Lupus nephritis – ANA positive, systemic symptoms
• Rapidly progressive GN – more aggressive presentation
• PSGN key differentiators: delayed onset, low complement, positive strep serology

📌 Management
• Supportive – the mainstay

• Manage fluid overload (fluid/salt restriction, diuretics)

• Control blood pressure (antihypertensives)

• Monitor renal function regularly
  • Antibiotics (e.g. penicillin) only if infection is still active
  • Immunosuppressants NOT routinely indicated
  • Hospitalisation if hypertensive crisis, significant oedema, or oliguria

📌 Prognosis
• Excellent in children – most recover fully in weeks to months
• Adults may have slower recovery or long-term risks
• Follow-up is crucial to monitor renal function and blood pressure

📌 Complications
• Acute kidney injury
• Persistent hypertension
• Chronic glomerulonephritis
• End-stage renal disease (rare)
• Higher risk in adults or those with comorbidities

🎧 FREE MSRA PODCAST – Glomerulonephritis: Your High-Yield Essentials

Complex but crucial—glom up your knowledge! We distil glomerulonephritis into bite-sized facts: definitions, causes, classic presentations, management, complications, and what to never miss for MSRA and real-world practice.

🧠 Key Learning Points

Definition
• Glomerulonephritis = Inflammation of the kidney’s glomeruli (tiny blood filters), usually immune-mediated
• Can be primary (kidney only) or secondary (as part of wider diseases, e.g. lupus)

Causes & Risk Factors
• Infections: Post-strep GN is classic
• Autoimmune: SLE, vasculitis (e.g. Goodpasture’s)
• Drugs, toxins, genetic predisposition, diabetes, hypertension, family history

Pathophysiology
• Immune attack damages the glomerular filters:
 – Protein & blood leak into urine (proteinuria, haematuria)
 – Filtration fails: reduced urine output, rising creatinine, fluid overload

Patterns (Biopsy):
• Minimal Change: Kids, steroid responsive, relapses
• FSGS: Older children/young adults, often steroid-resistant
• Membranous: Often idiopathic, variable Rx
• MCGN: Low C3, linked to infection/SLE
• Crescentic (RPGN): Rapid kidney decline, urgent

Clinical Presentations
• Asymptomatic (silent): Found on urine dip
• Nephrotic syndrome: Heavy proteinuria, low albumin, oedema
• Nephritic syndrome: Haematuria, some proteinuria, hypertension
• Rapidly Progressive (RPGN): Fast decline, crescentic pattern
• Chronic GN: Ongoing haematuria/proteinuria, hypertension, slow decline

Diagnosis
• Urinalysis: Protein, blood, casts
• Bloods: Renal function, complements, autoantibodies
• Immunology: ANA, ANCA, anti-GBM, infection screens
• Imaging: Renal ultrasound
• Renal biopsy: Key for definitive diagnosis

Management
• General: Blood pressure control (ACEi/ARB = kidney-protective), statins for cholesterol, salt restriction, diuretics
• Immunosuppression: Steroids, cyclophosphamide, other agents (type-specific)
• Treat underlying cause
• Advanced: Dialysis or transplant if kidney failure develops

Complications
• Chronic kidney disease and end-stage renal failure
• Hypertension (biggest driver of progression and CV risk)
• Nephrotic syndrome: Clots, infections
• Fluid overload, electrolyte disturbances

Memory Aid:
“GN = Glomeruli Neglected by the immune system!”
Nephrotic = Protein loss + Puffy (oedema), Nephritic = Inflammation + Red urine + Raised BP
BP is key—control it to control GN!

⚕️ FREE MSRA PODCAST – Nephrotoxicity due to Contrast Media
🎧 Understand this high-risk complication from contrast agents – vital for imaging safety and renal protection during clinical practice.

🧠 Key Learning Points

📌 Definition
• Acute kidney injury triggered by iodinated contrast, typically seen within 48–72 hours after imaging.

📌 Causes & Risk Factors
• Iodinated contrast agents (e.g. during CT/PCI)
• Pre-existing CKD
• Dehydration
• Diabetes mellitus
• Older age
• Heart failure
• Concurrent nephrotoxic meds (NSAIDs, diuretics)
💡 Mnemonic: "SICK KID" – Sepsis, IV contrast, CKD, K+ imbalance, Infection, Diabetes

📌 Pathophysiology
• Renal vasoconstriction → ↓ perfusion
• Direct tubular epithelial toxicity
• ↑ Oxidative stress
• Inflammatory cascade → tubular injury

📌 Symptoms
• Often asymptomatic initially
• ↓ Urine output
• Oedema, fatigue, confusion
• Classic AKI signs post-contrast

📌 Differential Diagnosis
• Pre-renal AKI (hypovolaemia)
• Acute tubular necrosis
• Drug-induced nephritis
• Post-renal obstruction

📌 Diagnosis
• ↑ Serum creatinine ≥25% from baseline within 3 days
• ↓ eGFR
• Urinalysis: proteinuria, casts
• Exclude other AKI causes
💡 Always compare pre- and post-contrast creatinine

📌 Management
• Prevention is key

• IV 0.9% NaCl: 1mL/kg/hr 12h before + 12h after

• Hold metformin for 48h post-contrast

• Use low/iso-osmolar agents
  • Supportive care

• Monitor fluids, electrolytes

• Avoid further nephrotoxins

• Dialysis if severe AKI
  🧪 N-acetylcysteine no longer recommended

📌 Complications
• CKD progression
• Electrolyte imbalances
• Temporary or permanent dialysis

📌 Prognosis
• Often reversible with early recognition
• Full recovery in days–weeks in most cases
• ↑ risk of long-term damage if baseline CKD or recurrent episodes

🎧 FREE MSRA PODCAST – Minimal Change Disease (MCD)
A high-yield breakdown of this classic nephrotic syndrome cause – ideal for quick, focused revision on a major paediatric renal condition.

🧠 Key Learning Points

📌 Definition
• Minimal Change Disease (MCD) is a glomerular disease that causes nephrotic syndrome.
• Despite severe protein loss, light microscopy of kidney biopsy appears normal – hence "minimal change".
• Electron microscopy reveals podocyte foot process effacement, explaining the functional leak.

📌 Causes & Risk Factors
• Often idiopathic, especially in children.
• Potential immune-related triggers: infections, vaccinations, allergies.
• Secondary causes: NSAIDs, rifampicin, Hodgkin lymphoma, thymoma, infectious mononucleosis.
• Peak age: 1–10 years.
• Slight male predominance.
🧠 Mnemonic: "MINIMAL" = Most Idiopathic, Nephrotic, Immune, NSAIDs, Malignancy (Hodgkin), Allergies, Little boys

📌 Pathophysiology
• Immune system → cytokine release → damage to glomerular basement membrane.
• Loss of negative charge → albumin leaks into urine.
• Podocyte damage leads to selective proteinuria (mainly albumin/transferrin).
🧠 Tip: Albumin is negatively charged – normally repelled. Loss of charge = albumin leaks → oedema.

📌 Clinical Presentation
• Periorbital & leg oedema
• Foamy urine (proteinuria)
• Fatigue, reduced appetite
• Weight gain (from fluid retention)
• Normal BP (unlike other nephropathies)
• Selective proteinuria is a key clue
🧠 Think: “PALE SWELL” = Proteinuria, Appetite ↓, Lethargy, Edema (esp. face), Swollen legs, Weight ↑, Electrolytes okay, Low BP

📌 Differential Diagnosis
• Focal segmental glomerulosclerosis (FSGS)
• Membranous nephropathy
• Lupus nephritis
• Diabetic nephropathy
• A biopsy is key to confirming MCD and excluding others

📌 Investigations
• Urine dip & ACR: proteinuria
• Bloods: ↓ albumin, ↑ lipids, renal function
• Biopsy:
 – Light microscopy = normal
 – Electron microscopy = effacement of podocyte foot processes
🧠 Tip: Selective albuminuria + normal light microscopy = suspect MCD

📌 Management
• First-line: Prednisolone (corticosteroids)
 – ~80% remission in children
• Steroid-dependent/resistant:
 – Cyclophosphamide or calcineurin inhibitors
• Monitor for relapse, manage side effects
• Salt restriction + fluid balance management
🧠 Mnemonic: "MCD = Mostly Corticosteroids Do it"

📌 Complications
• Relapses: common in children (1/3 frequent relapsers)
• Steroid side effects: growth delay, weight gain, glucose intolerance, infection risk
• Rare: progression to CKD or ESRD
• Thromboembolic risk (due to nephrotic state)

📌 Prognosis
• Excellent in children: 80% remission with steroids
• Most grow out of frequent relapses
• Adults: prognosis more variable, higher CKD risk
🧠 Tip: Frequent relapses often resolve by adolescence

✅ MSRA Deep Dive: Metabolic Acidosis – Master the Acid-Base Puzzle
In this focused episode, we break down metabolic acidosis — a fundamental yet often misunderstood topic. From decoding arterial blood gas results to calculating the anion gap, we guide you step-by-step through the essentials of recognising, investigating, and managing this condition. Tailored for the MSRA exam, this is your high-yield companion to cracking acid-base disorders with clinical confidence.

🧠 Key Learning Points

📌 Definition
• Metabolic acidosis = low blood pH (<7.35) with low serum bicarbonate (<22 mmol/L)
• It's not a diagnosis, but a marker of an underlying issue — a consequence, not a cause

📌 Anion Gap (AG) Classification
• Formula: Na⁺ + K⁺ − (Cl⁻ + HCO₃⁻)
• Normal AG = 8–16 mmol/L (without K⁺) or 10–18 mmol/L (with K⁺)
• Raised AG → Accumulation of unmeasured acids
• Normal AG (Hyperchloremic) → Bicarbonate loss compensated by chloride increase

📌 ABG Diagnosis Criteria
• pH < 7.35
• HCO₃⁻ < 22 mmol/L
• PCO₂ may decrease via respiratory compensation
• Use Winter’s Formula to assess compensation:
→ Expected PCO₂ = (1.5 × HCO₃⁻) + 8 ± 2
→ A mismatch = mixed acid-base disorder

📌 Causes by AG Classification
Raised AG Metabolic Acidosis (MUDPILES mnemonic):

• M: Methanol

• U: Uraemia (renal failure)

• D: DKA

• P: Propylene glycol

• I: Iron, Isoniazid

• L: Lactic acidosis

• E: Ethylene glycol

• S: Salicylates

Normal AG (Hyperchloremic):

• GI Bicarbonate loss (e.g. diarrhoea, pancreatic fistula)

• Renal Tubular Acidosis

• Drugs: Acetazolamide

• Addison’s disease

📌 Pathophysiology Categories

1. Increased acid load – lactic/ketoacidosis, toxins

2. Loss of bicarbonate – GI/renal

3. Reduced acid excretion – renal failure, RTAs

4. Buffering system failure – depletion of bicarbonate reserves

📌 Symptoms
• Kussmaul breathing (deep, rapid)
• Fatigue, confusion, nausea, vomiting
• Abdominal pain, hypotension
• In severe cases: shock, coma, arrhythmias
• Children may show growth delay or signs of rickets in chronic acidosis

📌 Clinical Clues & Risk Factors
• History of:

• Diabetes (DKA)

• Renal failure

• Diarrhoea/fistulae

• Alcohol abuse

• Toxin ingestion
  • Red flags:

• Tinnitus or visual changes (salicylates/methanol)

• Fruity breath (DKA)

• Altered consciousness

📌 Investigations
• ABG (to confirm low pH, bicarbonate)
• Electrolytes (for AG calculation)
• Serum lactate, glucose, creatinine
• Urine ketones, microscopy
• Urinary AG – helps distinguish renal vs GI causes in normal AG acidosis
• Osmolar gap – suspect toxic alcohols
• Specific tests: plasma salicylates, methanol, iron levels
• ECG, CXR, cultures, FBC, LFTs as guided by context

📌 Management Framework

1. Treat the underlying cause – this is the only definitive treatment

   • DKA: IV insulin, fluids

   • Renal failure: Dialysis

   • Toxin ingestion: Antidotes, dialysis

2. Supportive care

   • Oxygen, IV fluids

   • Monitor ECG, vitals, consciousness

   • Correct electrolytes

3. Sodium bicarbonate?

   • Controversial; may be used if pH < 7.1 and life-threatening

   • Risks: fluid overload, overshoot alkalosis

4. Dialysis – if severe acidosis, refractory hyperkalaemia, or certain poisonings

📌 Prognosis & Complications
• Depends on cause, severity, and speed of diagnosis
• Good outcome if prompt diagnosis + cause treated
• Complications if untreated:

• Cardiac arrhythmias

• Organ failure

• Cardiovascular collapse

• Death

🎧 FREE MSRA PODCAST – Lower Urinary Tract Infection (UTI): Fast-Track the Essentials

Super common, often overlooked, and full of classic exam pitfalls! We break down lower UTIs into need-to-know clinical pearls—diagnosis, management, and what NOT to miss in practice or for the MSRA.

🧠 Key Learning Points

Definition
• Lower UTI = Infection of the bladder (cystitis) and/or urethra
• Most commonly affects women; classified as uncomplicated or complicated based on risk factors

Types & Classification
• Uncomplicated UTI: Healthy, non-pregnant women, no urinary tract abnormality
• Complicated UTI: Men, children, pregnant women, those with structural or chronic health issues

Causes & Pathogens
• Bacteria: E. coli (most common, ~80%), others include Klebsiella, Proteus, Staph saprophyticus
• Usually ascends from the GI tract via the urethra; can also enter via catheters or rarely via blood

Risk Factors
• Female anatomy (short urethra), sexual activity, pregnancy, menopause, catheterisation
• Diabetes, immunosuppression, recent antibiotics, structural abnormalities, institutional care

Symptoms
• Dysuria (painful urination), frequency, urgency, suprapubic pain, cloudy/foul-smelling urine, haematuria
• Fever and loin pain suggest upper UTI
• Acute confusion may be the only sign in elderly patients!

Diagnosis
• Clinical: Symptoms + urinalysis (nitrites/leukocytes)
• Urine culture: Gold standard (especially for men, pregnant women, or if not responding)
• Don’t treat asymptomatic bacteriuria, EXCEPT in pregnancy (risk of pyelonephritis/preterm birth)

Management
• Antibiotics:
 – Non-pregnant women (uncomplicated): 3 days (e.g. trimethoprim, nitrofurantoin)
 – Men/pregnant women: 7 days
• Analgesia (paracetamol, NSAIDs), increased fluids
• Cranberry NOT recommended for treatment or prevention
• Backup (delayed) prescription option for mild cases in healthy women

When to Refer
• Failure to respond, recurrent or complicated UTIs, unexplained haematuria
• Men with recurrent UTI, or suspicion of cancer (NICE: visible blood, age >60, recurrent UTI)

Complications
• Pyelonephritis (upper UTI), sepsis, recurrent infection, kidney damage
• In men: prostatitis, prostatic abscess
• In pregnancy: preterm delivery, low birth weight, maternal anaemia (ALWAYS treat asymptomatic bacteriuria!)

Memory Aid:
UTI = “Urine That Irritates” (Urgency, Trouble peeing, Infections!)
Don’t forget: “Don’t treat if NO symptoms—EXCEPT if she’s pregnant!”
