[Instillagel in prevention of postoperative urinary tract infection--randomized trial]

The progress of operative technique, introduction of new drugs, modernizing of medical equipment are the cause of long and complicated operations. For that reason, the number of patients, who need the catheterization of the urinary bladder is increasing. The use of the vesical catheter over 5 days is the cause of the urinary tract infection (bacterial and mycotic), the bacteraemia and the extension of the time of recovery. The aim of the study was the estimation of the usefulness of the preparation Instillagel used at the time of the urinary bladder catheterization in the patients before an operation, in aspect of frequency of urinary tract infection. Between January and December 2000, 59 patients were selected for the study. The patients were divided into two groups. In the first group, the preparation Instillagel was used at the time of the catheterization. In the control group 2% Lignocainum hydrochloricum was used at the time of the catheterization. The study was prospective and randomized. The usefulness of the preparation Insillagel was estimated through the comparison of frequency of the urinary tract infection in both groups. The catheterization of the urinary bladder was performed according to aseptic principle. The difference between number and age of the patients in both groups was not statistically significant (p = 0.8538). The time of the keeping of the vesical catheter was similar in both groups (p = 0.576635). The urinary tract infection estimated on the basis of clinical symptoms and laboratory findings was diagnosed in 13 patients (5 patients in the first group, and 8 patients in the control group). The frequency of urinary tract infection was not statistically significant in both groups.

The urinary tract infection is frequent complication in patients with catheter in the urinary bladder, before operation. The frequency of urinary tract infection was not statistically significant in both groups. The discomfort and pain occurred with the same frequency in both groups.
