Transurethral resection of the prostate

For recommendations for prophylaxis in radical prostatectomy, see Open or laparoscopic urological procedures.

Consider the principles for appropriate prescribing of surgical antibiotic prophylaxis (see Principles for appropriate prescribing of surgical antibiotic prophylaxis) and the general principles of surgical antibiotic prophylaxis for urological surgery. Surgical antibiotic prophylaxis is indicated for transurethral resection of the prostate.

Patients undergoing transurethral resection of the prostate should be screened for bacteriuria preoperatively (see Screening for preoperative bacteriuria). For patients treated for bacteriuria preoperatively, modify the choice of surgical antibiotic prophylaxis based on the results of culture and susceptibility testing.

For prophylaxis for transurethral resection of the prostate, in the absence of culture and susceptibility test results, use:

gentamicin 2 mg/kg up to 180 mg intravenously over 3 to 5 minutes, within the 120 minutes before the procedure12; intraoperative redosing is unlikely to be required (see here ). Do not give additional doses once the procedure is completed. surgical prophylaxis, urological: transurethral resection of the prostate gentamicin    

If gentamicin is contraindicated (see Contraindications and precautions to gentamicin for surgical prophylaxis), use:

cefazolin 2 g intravenously, within the 60 minutes before the procedure; intraoperative redosing may be required (see here ). Do not give additional doses once the procedure is completed. surgical prophylaxis, urological: transurethral resection of the prostate cefazolin    

Gentamicin is preferred to cefazolin for prophylaxis for transurethral resection of the prostate because it is likely to have activity against a greater percentage of the bacteria associated with postoperative infection. The risk of gentamicin toxicity is very low when it is given as a single dose for prophylaxis.

1 If the patient is obese (for adults, body mass index 30 kg/m2 or more), use adjusted body weight (see ../Aminoglycoside-use-in-special-patient-groups/c_ABG_Aminoglycoside-use-in-special-patient-groups_topic_5.html#c_ABG_Aminoglycoside-use-in-special-patient-groups_topic_5__fig-504) to calculate the dose.

2 Do not use gentamicin for surgical prophylaxis in adults with a CrCl less than 20 mL/min; seek expert advice. For children with kidney impairment, seek expert advice on gentamicin use.Return
