Abstract
Summary— The risk of single catheterisation in females with urinary incontinence and/or genital prolapse was studied in patients referred for urodynamic examination.Two hundred and eighty‐six single catheterisations were performed followed by a mid‐stream specimen 1 week later, and in 31 of these the initial specimen contained more than 105bacteria.Following catheterisation bacteriuria occurred in 5 (2%) of the patients with initially sterile urine.The phenomenon of “asymptomatic bacteriuria”, “transient significant bacteriuria” and “bladder defence mechanism” is discussed.The risk of introducing urinary tract infection in urodynamic studies is low.
