Abstract

Background: One of the complications of urodynamic study is urinary tract infection. The aim of this study was to determine the rate of urinary tract infection (UTI) after UDS in patients referred to the pelvic floor clinic with regard to the specific conditions of these patients, such as presence of pelvic organ prolapse and high post voiding residual volume (PVR).

Methods: In a prospective descriptive-analytic study, 146 female candidates for UDS from January 2016 to June 2017 entered the study. Patients were examined for urinary tract infection before UDS (up to 5 days before USD) and were enrolled in the study if they did not have bacteriuria or urinary tract infection. Patients did not receive antibiotic prophylaxis before performing UDS. The patients were asked to do U/A and U/C three days after the UDS test.

Results: Among the 146 patients, 9 (6.2%) patients had considerable bacteriuria and 7 (4.8%) patients had UTI. The mean maximum detrusor pressure during urination and abnormal PVR before UDS had a significant correlation with positive urinary cultures after UDS (p<0.05).

Conclusion: The results showed that this diagnostic procedure is low risk and the prophylactic antibiotic therapy is not required before UDS in pelvic floor clinic. It seems that prophylactic antibiotic therapy is only appropriate in case of PVR greater than 50 ml and possibly of the high detrusor pressure.
