Take home message
• Painless haematuria in >40 yo = malignancy
until proven otherwise

When to refer to Urology:
– >5 mm/Staghorn/stone doesn’t pass/infection +
obstruction/urosepsis/ARF/Solitary kidney/Bilateral obstruction
Analgesia
– Paracetamol, NSAIDs (Indomethacin Suppository), Opioids (oral/SC/IV)
Anti-emetics
IVF
Medical therapy: CCB (Nifedipine), alpha blockers (Tamsulosin)
Surgical:
– Extracorporeal Shock Wave Lithotripsy (ESWL)*/Ureterscopic
lithotripsy/Percutaneous nephrolithotomy
Send stone for analysis
Dietary modifications (inc fluid intake)
Urine modification:
– Ca stones: Thiazide diuretic and low Na diet
– Uric Acid stones: Allopurinol
– Cystine stones: Alkalinization of urine (Ural – NaHCO3/Potassium Citrate)
Mx
• Stone radiopauqe?
– No  Probable uric acid stone
• Fluids + Analgesia; Alkalinize urine w Potassium Citrate
– Yes  Fluids + Analgesia  stone >5mm?
• Yes  Refer to Urology
– Staghorn Calculus  Percutaneous lithotomy + ESWL
– Calyceal/Upper ureteral calculus ESWL
– Distal ureteral calculus  Ureteroscopy/ESWL
• No  Strain urine and continue hydration + analgesia.
Await stone to pass
– Renal Tract USS in 2/52 if hydronephrosis/multiple stones on
initial evaulation
Nephrolithiasis
• Composition:
– 80%: Ca stones:
• Ca oxalate
• CaPO4
– Uric Acid (RADIOLUCENT)
– Struvite (Mg, Ammonium, PO4)
– Cystine
