[Gram-positive cocci in the urinary tract. Do they influence the postoperative course of transurethral prostatectomy?].

The influence of gram-positive cocci on the postoperative course of transurethral prostatectomy was analysed on 463 patients. The half of isolated cocci was Enterococcus, followed by S. epidermidis and S. aureus. The rates of postoperative urinary infection by gram-negative bacilli were nearly the same for patients with preoperative gram-positive cocci infection and those without any of bacteria (3/79 vs. 9/310). Patients who developed new infection with gram-negative bacilli had fever, in contrast to patients with new gram-positive cocci infection. Gram-positive cocci prolonged the postoperative pyuria but not so long as gram-negative bacilli. All these findings suggest that infection caused by gram-positive cocci is not so severe as that caused by gram-negative bacilli.
