[Urinary incontinence and bacteriuria in women]

We analyzed the urodynamic data and their relationship with significant bacteriuria in 103 consecutive female patients (mean age = 55.7 yrs) with urinary incontinence. Significant bacteriuria was observed in 25.2% of the cases. E. coli was the pathogen most frequently isolated (70.3%). Significant bacteriuria was demonstrated in 29.3% of the patients with urge-incontinence. The most frequent type of incontinence in patients with bacteriuria was no urodynamic reproduction of urinary incontinence (42.8%). Bladder instability was not associated with significant bacteriuria (27.2%). Significant bacteriuria was observed in 75% of the patients with lower urinary tract obstruction, 66.6% of the patients who voided by abdominal straining and 26.3% of those with postvoiding residual urine. These findings indicate that urine culture should be done in patients with no urodynamic reproduction of urinary incontinence. There was no statistically significant correlation between urge-incontinence/bladder instability and significant bacteriuria. Consequently, antibiotics should not be used routinely in female urinary incontinence.
