A Study for Clarifying the Necessity of Additional Antibiotic Therapy in Patients Undergoing TURP, Given Antibiotics During Catheter-indwelling and Showing Sterile Urine after Catheter-removal / 대한비뇨기과학회지

ABSTRACT

Faced with patients who underwent TURP and who were given antibiotics until catheter-removal, usually complain of urinary frequency or burning on ruination and showing sterile urine (less than l00 bacteria per ml., in clean-caught midstream about 24 hours after catheter-removal), we often hesitate to make a decision whether they should be given antibiotics or not. So we divided 27 such patients into three groups group l ; 7 patients, no additional antibiotics after catheter-removal, group 2; 12 patients, antibiotics for one week after catheter-removal and we performed weekly urine culture for clarifying the necessity of additional antibiotic therapy and its appropriate duration, if necessary. The following results and conclusions were obtained. I. Group l showed bacteriuria in 86%(6 of 7 patients). 2.Group 2 and 3 showed bacteriuria 5%(1 of 20 patients). 3. These data suggested that additional antibiotic therapy rather than stopping antibiotic therapy might be justified(P less than 0.001). 4. Group 2 showed no bacteriuria and group 3 showed bacteriuria in one patient which disappeared promptly. Namely, there was no practical difference in the incidence of bacteriuria between the two groups. 5. 9 cases of fungiuria were found, all of which developed in patients given antibiotics perioperatively for more than 2 weeks. 6. Considering the above items and cost-effectiveness, a week`s additional antibiotic therapy is probably an appropriate answer to treating the above-mentioned patients. 7. Main causative organism in post-TURP bacteriuria was Pseudomonas spp(4of 7 cases).
