Purpose : We evaluated accordance between preoperative urine culture and pelvic urine culture in percutaneous nephrolithotomy.
Materials and Methods : Urine samples of patients awaiting percutaneous nephrolithotomy for renal stones were collected for urine culture. During surgery, renal calyx was punctured with Chiba needle, and then pelvic urine was aspirated with a syringe. The collected pelvic urine samples were cultured. In each cases, patients’ age, sex, BMI, stone laterality, size, ureteropelvic junction obstruction, stone composition, preoperative urine culture, pelvic urine culture and postoperative febrile urinary tract infection were analyzed. According to accordance between pelvic urine culture and postoperative urine culture, cases were categorized into two groups and each parameters were compared between two groups.
Results : 65 renal units of 62 patients were analyzed. Male were 49 and female were 16. Mean age was 57.3 years old, mean body mass index was 24.6 kg/m2. Mean stone size was 35.8 mm in diameter. Positive preoperative urine culture were 12 (18.5%) and positive pelvic urine culture were 13 (20.0%) (Table 1). The number of cases with accordance between two culture results was 58 (89.2%) and cases without culture accordance was 7 (10.8%). In positive culture results cases, there were accordance between both antibiotic susceptibility results. 7 patients had postoperative fever over 38 centidegree, two had positive both preoperative and pelvic urine culture and one had only positive pelvic urine culture. Between the culture accordance and non-accordance groups, only pelvic urine culture positive was statistically different (Table 2).
Conclusions: In patients with renal stones, the rate of accordance between preoperative urine culture and pelvic urine culture during percutaneous nephrolithotomy was high. However, there may be some patients with urinary tract pathogens present normal urine analysis.
