Trial of Randomized Antibiotic Administration in Percutaneous Nephrolithotomy

• Status: Completed
• Phase: Phase 3

Summary

The Investigators objective is to compare the clinical efficacy of a single-day protocol with a short-course protocol for PCNL. The investigator hope is to reduce the use of possibly unnecessary prolonged antibiotic use, reduce hospital costs and prevent the further propagation of resistant microbes.

Detailed description

For large renal stone burdens and/or complex stones, Percutaneous Nephrolithotomy (PCNL) has become the mainstay for treatment, replacing open kidney stone surgery since it's introduction in 1976. However, PCNL is not without its complications, specifically infectious. The procedure carries up to 25% incidence of infectious complications with approximately 1% rate of severe sepsis even with completely sterile conditions. Therefore, the use of antibiotics becomes paramount, but to date there are no PNCL specific guidelines for the appropriate duration and class of antibiotics. This fact leaves the practicing urologists to their own subjective experiences to the guide them. In addition, in an age where there are increasing numbers of resistant microbes the judicious use of antibiotics is in even more paramount. The investigators of this project, purpose a randomized intention to treat prospective study to explore the duration and type of antibiotics in a larger population then previously studied. The investigators hypothesize that there will be no difference in complications between two groups: 1) 24 hours of perioperative antibiotics versus 2) Continued antibiotics until the removal of any external catheters. The investigators will model the antibiotics choices and duration after the 2013 American Urological Association, (AUA) Urologic Surgery Antimicrobial Prophylaxis recommendations, modified by our local antibiogram as necessary. The investigators' objective is to compare the clinical efficacy of a single-day protocol with a short-course protocol for PCNL. Our hope is to reduce the use of possibly unnecessary prolonged antibiotic use, reduce hospital costs and prevent the further propagation of resistant microbes. Antibiotic detail: cephalosporins or aminoglycoside + metronidazole or clindamycin and the alternative for allergies being aminoglycoside/ sulbactam or fluoroquinolone Looking at the same drugs and doses the variable is the timeframe of the medication

Conditions

• Kidney Stones

Interventions

Type	Name	Description
DRUG	cephalosporins	Patients were randomly assigned to the interventional arm or the control arm through stratified randomization. In addition to perioperative antibiotics, those in the interventional arm only received antibiotic course for up to 24 hours after procedure, while those in the control arm received antibiotics until external catheters were removed based on surgeon preference. Ancef, a 1st generation cephalosporin, was used as the primary antibiotic, which was started within 60 minutes of the procedure. Dosing was 1 gram IV every 8 hours and was adjusted for renal dosing as needed
DRUG	Fluoroquinolones	If the patient has an allergy to penicillin or cephalosporin, then Ciprofloxacin was used instead and started within 120 minutes of the procedure at 400mg IV and would be continued every 12hrs if patient has a normal creatinine clearance
DRUG	Clindamycin	If allergic to penicillin, cephalosporins, and fluoroquinolones, 900 mg Clindamycin started within 60 minutes prior to initial surgical incision.
DRUG	Ampicillin/Gentamicin	5 mg/kg as a single dose of Gentamicin within 60 minutes prior to surgical incision; given in combination with 2 grams of ampicillin in cases where allergic to fluoroquinolone and cephalosporin
