STUDY FOR RELATION BETWEEN BACTERIA WITHIN STONES AND POST-OPERATIVE URINARY TRACT INFECTION IN PERCUTANEOUS NEPHROLITHOTOMY

Abstract

Bacterial cultures of removed calculi and post-operative urine were performed for 40 patients who had had percutaneous nephrolithotomy, to study the relation between them.
Although stone cultures were positive in 17 cases (42.5%), the same bacteria were detected in both stone and post-operative urine in only one case. In this case, from our experience contamination of instruments seemed to be the source of infection.
We concluded bacteria residing within the stone rarely cause post-operative urinary tract infection in percutaneous nephrolithotomy.
Technical problems in these studies were also discussed.
