The relationship between urea-splitting organism in the urine and urinary stone is well known.
We have checked bacteriologic study of 28 urinary stones after surgical removal of stone and brushing, and following results were obtained.
1. Positive stone culture were 6 cases (21.4%).
2. Organisms were Pseudomonas, Klebsiella, Proteus, Serratia, Staphylococcus and Enterococcus.
3. Antibiotics sensitivity of 6 cases of infected stones were Klebsiella, proteus: 2) Amikacin, Pseudomonas:
1) Ampicilline, Serratia: 1) Cefamezine, Staphylococcus: 2) Kanamycin, Gentamycin, Enterococcus: 3) Penicilline.
1) Sensitive 2) Moderately sensitive 3) Relatively resistant.
4. The most prevalent age group of infected stone was between 40-49.
5. Ureter was the most favorable site of infected stone and multiple stone were 2 cases.
6. Positive urine culture were detected in all of 6 cases of infected stone.
7. In 4 cases of infected stone, organisms of stone culture and urine culture were identical. They were Pseudomonas, Enterococcus, Proteus, Staphylococcus.
8. In 2 cases of infected stone, organisms of stone culture and urine culture were not identical. They were Serratia, Klebsiella in stone culture and proteus, E. coli in urine culture respectively.
