title: [Giant renal lithiasis].
abstract: OBJECTIVE
  To describe a case of giant renal calculus.
  
  
  RESULTS
  A 57-year-old female with a previous history of left renal calculus 30 years earlier, consulted for episodes of gross hematuria. The imaging studies showed a giant, spherical calculus, 9 cm in diameter, in the left renal pelvis with hydronephrosis and remaining renal parenchyma functioning. The patient refused surgery.
  
  
  CONCLUSIONS
  Giant renal calculi may progress slowly, without symptoms and without abolishing renal function.
