STUDY OBJECTIVE: To estimate the frequency of vaginal voiding as the cause of daytime urinary leakage in girls, and to study the effect of instructions intended to alleviate the problem.
SETTING: Girls with vaginal voiding were identified in a group of girls referred because of daytime urinary leakage. They were evaluated by a noninvasive screening protocol. Girls with vaginal voiding were instructed on how to achieve better toilet habits.
PARTICIPANTS: Twelve girls with vaginal voiding.
RESULTS: Vaginal voiding was found in 12 of 39 girls with daytime urinary leakage. Their age ranged between 8.5 and 13.9 years. They all had history of small leakage immediately after voiding. A body mass index greater than the corresponding 85th percentile was noted in 5 girls, and labial fusion was noted in 2 girls. The complaint disappeared in 10 girls and improved in the remaining 2 girls after instructions on how to achieve better toilet habits.
CONCLUSIONS: Vaginal voiding is common in girls. It occurs in girls at risk of overweight, in girls with labial fusion, and in girls adopting a hairpin posture while sitting on the toilet. The diagnosis is obtained by an adequate history. Proper voiding instructions resolve the problem.
