Introduction and objectives: To compare the efficacy of tobramicin and tobramicin + ciprofloxacin for prevention of transrectal prostatic biopsy infectious complications. We revised our complications, microorganism most common in the infectious complications, and their sensibility. Material and methods: Prospective and randomized study in 153 patients with 157 prostatic biopsies. The 71 patients in group A were treated with intramuscular tobramicin 100 mg, one dose 30 minutes before biopsy and another one 8 hours afterwards. The 85 patients in group B were treated with the same tobramicin doses and oral ciprofloxacin 500 mg, one dose 30 minutes before biopsy and afterwards they continue with the ciprofloxacin every 12 hours during 3 days. Results: we did 71 biopsies in group A and 86 in group B. 50 (31,8%) patients had hematuria, 20 (12,7%) fever, 15 (9,5%) hemospermia, 7 (4,4%) perineal pain, one (1,2%) orchiepididymitis and another one (1,2%) urinary retention. The patients who had fever were 15 of the group A and 5 of the group B (p=0,004). A total of 15 (21,1%) patients with fever of the group A needed to be treated in the hospital and 3 patients (3,5%) of the group B (p=0,0006). E. coli growthed in 67% of the blood cultures and amoxicillin-clavulanic, tobramicin and third generation of cephalosporins were the antibiotics more eficacious. Conclusions: Prophylaxis scheme with tobramicin plus ciprofloxacin was more efficacy that tobramicina alone in transrectal prostatic biopsy. Hematuria was the most common complication. E.coli was the microorganism most frequent in infectious complications after prostatic biopsy and amoxicillin-clavulanic, tobramicin and third generation of cephalosporins the most effective antibiotics in our hospital.
