[Chronic renal failure and urinary stone]

Urinary lithiasis is an uncommon cause of chronic renal failure. Risky stones of chronic renal failure are cystinuria, tubular acidosis and chronic bowel diseases. Moreover, bilateral stones, late metabolic diagnosis and infection are factors that can induce an alteration of the renal function. Staghorn stone is a grave disease for the renal function and the life of the patient. There is no room for conservative treatment for staghorn stones. For solitary kidney, the stone treatment may improve the renal function. Incidence of stone in the dialysis population is 5-13%. In the dialysis population, it is recommended a yearly renal sonography and citrate, and magnesium treatment. All the urological procedures of stone removal are available in case of renal failure but the techniques must spare the renal function and avoid surgical complication. Urines must be with no infection and a urinary drainage is mandatory.
