summary

Bacteriological examination of 99 kidney stones were done. In all patients the
pretreatment midstream urine and kidney stones were analysed for bacterial isolates
50% of patients had positive kidney stones cultures ? mainly calcium phosphorate
stones. Bacteriological cultures of midstream urine were positive in 71,4% patients
with infected stones. 28% patients with infected stones had negative urine cultures.
The most of ften seen bacteria within the stones were: Enterobacteriaceae and
Pseudomonadaceae.
Conclusions
1. 50% of kidney stones were infected.
2. The infected stones and urinary tract infection were observed move often in
female tract infection were most fre±uent in phosphorate stone formers.
4. The fre±uency of infected stones was higher than the fre±uency of the signifi-
cant bacteriuria - important for eventual antibacterial prophylaxis.
