Objective: To evaluate the correlation between postvoid residual urine (PVR) and urinary tract infection (UTI) in women with pelvic floor dysfunction.

Methods: A retrospective chart review was carried out of all new patients with symptoms of pelvic floor dysfunction. PVR was assessed with transvaginal ultrasonography. UTI was diagnosed by urine culture in woman as growth of more than 100,000 colony forming units (CFU)/ml of the uropathogenic bacteria. 

Results: Two hundred and forty (82%) of 290 medical records were completed for this analysis. The overall percentages of PVR were 82.9% at 0-30 ml, 7.1% at 31-50 ml, 7.5% at 51-100 ml and 2.5% at more than 100 ml. The percentage of women who had  ≥ 30 ml PVR were 29% and 6% in pelvic organ prolapse (POP) stage II or greater with stress urinary incontinence (SUI) and SUI alone groups, respectively. The percentages of UTI were 27.1%, 35.3%, 11.1% and 33.3% for PVR at 0-30 ml, 31-50 ml, 51-100 ml and more than 100 ml, respectively.  Elevated PVR was not associated with UTI (P>0.05). 

Conclusions: Elevated PVR was not associated with UTI.  Women with POP stage II or greater and SUI tended to have higher PVR (more than 30 ml) compared to women who had SUI alone.
