Preoperative PBUC may not represent true colonization; therefore,
preoperative perioperative antimicrobial prophylaxis (PAP)
administration should be adjusted according to the individual risks of
PBUC-positive patients. Even if PBUC is negative, it should be kept in
mind that there may be growth in RPUC in patients with preoperative
hydronephrosis and low pelvis urine density.
