[Infective lithiasis. Treatment and complications].
OBJECTIVE
To establish the criteria for treatment of staghorn stones according to stone surface and distribution in cadaver kidneys.


METHODS
Retrospective study of 344 cases treated from 1985 to 1992 and classified into two groups according to treatment by extracorporeal lithotripsy or by percutaneous nephrolithotomy (PNL).


RESULTS
Mean age 48.69 years, prevalence of females and positive urinary culture in almost 70%, mainly Proteus. Stone composition was varied, but mainly magnesium ammonium phosphate. Treatment was by extracorporeal lithotripsy in 80.81% and by PNL in 19.9%.


CONCLUSIONS
Treatment of this type of lithiasis should be by combined surgical removal and medical treatment. Lithotripsy is advocated for large caliceal calculi and PNL for large pyelic calculi.
