A randomized controlled trial comparing the use of preoperative prophylactic single dose fosfomycin trometamol versus levofloxacin in prevention of post-PCNL infectious complications and sepsis.

the 3 groups were compared as regards the baseline data, preoperative data, intra-operative data, and post-op data.

A prospective randomized study, in which 300 patients admitted to urology department, Tanta university with renal stones prepared for PCNL were randomly distributed into 3 groups:

Group I, included 70 patients received single oral dose Fosfomycin 3 gm the night before the procedure.

Group II, included 70 patients received 5 days levofloxacin 500 mg once daily before PCNL Group III, included 70 patients will not receive preoperative treatment

The patients were evaluated by: complete hemogram, renal function, stone work-up, and MSU culture were done preoperatively.

NCCT was done for all included patients Intraoperative renal pelvic urine (collected after ureteral catheterization or at first puncture of pelvicalyceal system [PCS]) and stone fragments were collected in sterile plastic containers for culture. The samples were sent immediately (within 1 hour) to the laboratory for processing.

The following data were recorded and compared; patients' demographic data, stone characteristics, preoperative lab. Investigations, intraoperative data (OR time and complications) and postoperative data (SFR, complications especially infectious ones, sepsis and fever, hospital stay), and post-operative bacteruria.

Inclusion Criteria:

• adult patients with renal stones scheduled for PCNL

Exclusion Criteria:

• Unfit patients for surgery
• patients with active UT
• uncorrected coagulopathy
• pregnancy
