“…These differences between genders, which have also been confirmed in our study in both groups, may be caused by the anatomical and hormonal differences among male and female urogenital systems. Saez-Llorens et al [5] and Lohr et al [14] compared the MSU sampling techniques in children in their studies. However, both of these studies failed to demonstrate the effect of washing the genital area on reducing contamination rates.…”

“…The effect of urogenital cleaning with chlorhexidine-containing genital region cleansing wipes (GRCW) on urine culture contamination rates was evaluated. Various methods for decreasing contamination rates have been examined in previous studies [5,6,8,9,11]. However, in our literature search, no study evaluating contamination rates of urine culture after using GRCW was found.…”

“…Contamination, may lead to problems during interpretation and reporting of culture results. Even though direct MSU collection is still the most common method, various levels of contamination rates in urine samples have been reported in various studies [4][5][6][7][8]. In cases of contamination, resampling from patients is required.…”

Introduction: Urine culture is the gold standard test for revealing the microbial agent causing urinary tract infection (UTI). Culture results are affected by sampling techniques; improper sampling leads to contamination of urine and thus contamination of the culture with urogenital flora. We aimed to evaluate the effect of urogenital cleansing, performed with chlorhexidine-containing genital region cleansing wipes (GRCW) on contamination rates. Methodology: A total of 2,665 patients with UTI-related complaints and with urine culture requests from various outpatient clinics were enrolled in the study. Of the patients, 1,609 in the experimental group used GRCW before sampling, while 1,046 in the control group did not use any wipes. Results: The contamination rate in the experimental group patients was 7.7%, while it was 15.8% in the control group. Contamination rates were significantly higher in the control group than in the experimental group for both women and men. Contamination rates for children and adults were also significantly lower in the experimental group than in the control group. Conclusions: Our study, conducted in a large population, showed that the use of chlorhexidine-containing cleansing wipes significantly reduced urine culture contamination rates in both genders, in both child and adult age groups. Using GRCW, collection of urine after urogenital area cleansing will decrease the contamination problem.

Cleaning the genital area with plain water should always be performed before collecting urine samples, even if only a urine dipstick without culture is needed. What is Known: • Cleaning the genital area reduces the urine bacterial contamination rate in populations of toilet-trained pediatric patients. • There are no studies assessing the impact of cleaning the genital area on the quality of the urine dipstick, nor on which factors could affect the urine dipstick findings. What is New: • Falsely positive urine dipstick was found in 25.5% of the 612 prospectively enrolled toilet-trained and not-toilet-trained children. • Non-retractable foreskin and female gender significantly increases the relative risk of falsely positive urine dipsticks.
