Litiasis vesical gigante recurrente en el adulto. Reporte de un caso

Abstract

The occurrence of cases of giant urinary stones considered has diminished significantly in its frequency since the advent of antibiotics and the appropriate control of urinary tract infections. The diagnosis of them is based on symptomatology and imaging studies. We present a case of a 59-year-old man with recurrent giant bladder stones. The patient was diagnosed with two vesical stones after performing a computerized axial tomography of the urinary system and later a cystolithotomy was performed to remove stones of up to 1,435 g. The morphoconstitutional analysis of the calculus revealed brushite, carbapatite and struvite as main components. The metabolic evaluation indicated the presence of hypocitraturia and hyperoxaluria.  This is the first report in the country of a giant lithiasis  in which the composition of the stones indicate infectious processes as the possible causes of formation.
