Abstrakt: Objectives: Urinary incontinence (UI) is a frequent cause of admission to pediatric nephrology outpatient clinics. The aim of this study was to determine whether anatomical changes in lower urinary tract structures (retrovesical angulation [RVA] and bladder neck position [BNP]) are associated with UI in pediatric patients with daytime-wetting in comparison to healthy children.
Methods: In this prospective study, patients with daytime UI diagnosed using the Dysfunctional Voiding Symptom Score of the International Children's Continence Society and 3-day-voiding/bowel diary were compared with an age- and sex-matched control group without incontinence. In addition to routine clinical evaluation, RVA and BNP were measured at rest using transabdominal ultrasound (TA-US). Intra-rater agreement was estimated.
Results: A total of 88 children were included in the study, with 44 children (22 boys, 22 girls) each in patient and control groups. RVA was significantly greater and BNP was significantly lower in the patient group versus control group (RVA: 134.30 ± 10.05 vs 127.94 ± 13.15, P = .013; BNP: 11.88 ± 4.53 vs 17.20 ± 5.55, P < .001, respectively). Irrespective of the presence of incontinence, girls had a significantly greater RVA than boys (P < .001). However, there was no difference between sexes in BNP values (P = .630). Intra-rater agreement was very strong for RVA (P < .001, r = .897), and strong for BNP (P < .001, r = .774).
Conclusions: TA-US imaging is a non-invasive and practical procedure routinely performed in pediatric patients presenting with UI complaints. Our study demonstrated anatomical changes in lower urinary tract structures in pediatric patients with UI. These changes should be considered in the diagnosis, follow-up, and treatment of patients with UI.
