OBJECTIVE: To review our series of lithiasis associated with megacalyosis, a rare disease entity.
METHODS/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.
