Abstract

Introduction: Constipation and urinary disorders are among the most common problems in childhood, and functional constipation is a recognized cause of urinary disorders after toilet training. Given the high prevalence of these conditions and the limited research on the temporal relationship between the onset of urinary disorders and constipation, this study aimed to assess the prevalence and types of urinary disorders, their association with functional constipation, and related ultrasound findings in children in Kashan. Methods and Materials: This cross-sectional study included 102 children aged 5–15 years who were referred to the pediatric clinic in Kashan during 1399–1400 and diagnosed with functional constipation based on Rome IV criteria. Data were collected using a structured checklist, ultrasound examination, and urine culture. Demographic information, duration of constipation, urinary symptoms, and ultrasound findings (including bladder wall thickness and residual urine volume) were recorded and analyzed statistically. Results: The mean age of participants was 6.86 ± 1.49 years; 52% were girls and 48% boys. The most common urinary symptoms were urinary frequency (79%) and dysuria (39.6%). Significant associations were found between voiding dysfunction and female gender (odds ratio ≈ 6), history of urinary tract infection, longer duration of constipation, increased residual urine volume, and greater bladder wall thickness (p0.05). Each additional month of constipation increased the risk of voiding dysfunction by 7%. Girls had a sixfold higher risk of developing voiding dysfunction compared to boys. Conclusion and Discussion: This study demonstrates that female gender, history of urinary tract infection, and longer duration of constipation are significant risk factors for voiding dysfunction in children with functional constipation. Early identification and management of constipation, especially in girls, may help prevent the progression of urinary disorders in this population.
