[Lithiasis in megacalyosis].
OBJECTIVE
To review our series of lithiasis associated with megacalyosis, a rare disease entity.


RESULTS
The clinical records of patients treated from 1976 to 1994 were reviewed. Of 39 cases of megacalyosis, 27 were associated with lithiasis and was slightly more prevalent in males (59.3%). Struvite and whewelite calculi were more prevalent and 40.7% also had urinary tract infection, E. coli, Pseudomonas and Proteus being the most frequent pathogens. ESWL with hyperhydration was the most frequently utilized treatment.


CONCLUSIONS
Megacalyosis is an embryogenic anomaly of Malpighi's pyramids that is associated with lithiasis in 69.2% of our series, frequently localized to the left side. We have found no significant difference according to sex or a hereditary component. IVP is the principal diagnostic method for megacalyosis. The frequent association of urinary tract infection should be taken into account when instituting treatment.
