Bacteremia from transurethral prostatic resection under prophylactic use of antibiotics.
We studied the incidence of the postoperative bacteremia developing in 44 patients undergoing transurethral resection of the prostate under prophylactic use of antibiotics. In 15 of the patients, postoperative endotoxinemia was also investigated. Postoperative bacteremia was found in 10 (22.7%) of the patients, in only one of whom septicemia developed. The incidence of bacteremia was not influenced by the kind of antimicrobial agent administered prophylactically, but was significantly higher in the patients with preoperative urinary tract infection or prostatitis on histological examination of resected prostatic tissue (p less than 0.01). Concerning species isolated from the blood, gram-positive cocci were isolated more frequently than gram-negative bacteria, and Staphylococcus epidermidis was the most common species. In 7 (70%) of the bacteremia patients an identical species was isolated from preoperative urine cultures. In the patients with bacteremia, significant increases in white blood cell count and maximal body temperature were found within 3 hours after the procedure as compared to before the procedure. To lower the postoperative bacteremic rate, appropriate and adequate antimicrobial agents must be used preoperatively in patients with infection of the genitourinary tract. As to blood endotoxin, the endotoxin levels in the patients with postoperative fever did not significantly differ from those of the patients without this complication.
