THE INFECTION RATE IN PATIENTS WITH CATHETER FOLLOWING URINARY TRACT SURGERY

ABSTRACT

Aim: Identfying at which rate the catheter settled into urinary system causes infection due to duration in spite of prophylactic antibiotic treatment in the patients underwent surgery because of urinary system pathology.

Material and Methods: The study population consisted of 16 patients who had urinary system pathology,underwent surgery and selected randomly in Pediatric Surgery Clinic were included the study. Urinary system catheters were applied to all patients after operation. Sefuroxim was begun to 10 of these patients, sefaperazon+sulbaktam to 1, ampicillin + sulbactam to 1, penicilin crystalyse to 1, amicasin to 1 and triemthoprim+sulphametoxasole to 2.Urine cultures were taken from the patients on 3rd, 7th and 10th days after operation and the rates of system infection identified were compared. When reproduction was identified in culture antibigram, the antibiotic treatment was changed due to the result of culture antibiogram. The catheters of all patients were extracted out on postoperative 10th day. The patients were delivered with the supression of triemthoprim+sulphametoxasole except ones who had reproduction in their urine cultures.       

Results: The study population consisted of 16 patients are composed of  11 (66 %) female and 5 (34%) male [mean age, 7.21±1.47 years (±SD); range, 0 to 14 years], Reproduction wasn’t observed at the urine cultures taken on 3rd day. Reproduction was observed at one of urine cultures taken on 7th day (enterococ). Reproduction was identified at three of the urine cultures taken on 10th day. (One of them was pseudomonas, two of them were candidas). The rate of reproduction was 6.25 % on 7th day and 23.08 % on 10th day. Although the ratio of reproduction on 10th day was higher than the ratio of reproduction on the 7th day, there was no significant difference between these two days (p= 0.625). 

Conclusion: We think that it is useful to investigate the antibiotic used when catheter is kept more than one week.
