Endoscopic Examination

Tze-Chen ChaoTaiwan Speaker Prevention of Surgical Site Infection: Endoscopic examinations and drainage tube related proceduresThe presentation outlines antibiotic prophylaxis in urologic examinations and drainage tube-related procedures. For diagnostic examinations like urodynamics and cystoscopy without manipulation, prophylactic antibiotics are generally not required in low-risk patients without UTI risk factors. Ureteroscopy has increased infection risk due to potential mucosal trauma, increased intrarenal pressure, and therefore requires antibiotic prophylaxis. For drainage procedures, DJ stent placement typically warrants prophylaxis except in carefully selected low-risk patients, as colonization rates increase with duration and certain risk factors such as diabetes, chronic kidney disease, malignancy, female gender, pregnancy, and emergency procedures. First-time nephrostomy placement requires single-dose prophylaxis due to renal parenchymal injury and bacteremia risk. On the other hand, routine exchanges of nephrostomy generally don't need prophylaxis unless tube obstruction occurs. The key principle is individualized risk assessment. Current evidence supports selective rather than universal prophylaxis to prevent infection and minimize bacterial resistance.Transurethral Surgery
