Abstract:
Objective To investigate the correlation between bacteria and upper urinary tract calculi (UUTC). Methods 530 cases of UUTC were enrolled in the study.Mid-stream urine culture was obtained before operation.Intraoperative pelvic urine culture,cotton swab culture of stone-incarcerated mucosal surface,pre- and post-sterilized stone culture were also carried out. Results Among 530 cases of UUTC,the stone culture showed positive (infectious stone) in 120 cases (22.6%),more prevalent in females than in males. Staphylococcus epidermidis and Escherichia coli were the predominant bacteria, accounting for 60.1% and 32.5%,respectively.The infection rate with which a stone size was ≥1.0 cm with coarse surface,loose density or radiolucent was much higher than that of size
