A total of 300 patients undergoing various types of urological procedures was studied for incidence of bacteremia. An osmotically stabilized anaerobic broth with sodium polyanethol sulfonate (Liquoid) yielded more positive blood cultures than any other culture system and was also the best system by far for recovery of anaerobes. The membrane filter showed faster growth and, therefore, facilitated faster identification of the infecting organism. There was a 31% incidence of bacteremia in the patients having transurethral resection of the prostate, 17% in the cystoscopy group, 24% in the urethral dilation group, and 8% in the urethral catheterization group. The organisms found most frequently isolated in blood cultures were enterococci and Klebsiella pneumoniae. Notable were a relatively large number of anaerobes and two protoplasts. The major source of the bacteremia was previous urinary tract infection, but evidence is presented which indicates that the prostate gland and the normal urethral flora are other significant sources.
