[Prospective study for the evaluation and prophylaxis of urinary tract infections, secondary to the intravesicular instillation of cytostatics].

The aim of this study is to ascertain the number of urinary infections that occur after every catheterization for the instillation of an endovesical cytostatic and to attempt to reduce the percentage of infections by means of specific plans and methods. The study was carried out during the months of April, May, June, July, September, October and November 1988 and the collection of urine for culture was laid down as standard practice in all patients before instillation. In the same way, a urine sample was studied if the patient displayed symptomatology after instillation. 474 instillations were carried out on 77 patients during the above-mentioned period of time. The number of urine samples collected with significant bacteriuria was 18, which represents 3.8% (reliability margin 2.2%-6%, p less than 0.05).
