Delineating the Diagnostic Concordance Between Pediatric Lower Urinary Symptoms Scoring and Voiding Diary in Pediatric Lower Urinary Tract Dysfunction

Background: This retrospective research endeavored to conduct a comparative evaluation of the Pediatric Lower Urinary Tract Symptoms Scoring (PLUTSS) system and the Voiding Diary (VD). The correlation between these diagnostic tools, their prognostic value for treatment outcomes in pediatric Lower Urinary Tract Dysfunction (LUTD), and their relationship with patients' sociodemographic characteristics were also explored. Methodology: The study data for the cohort established between December 2005 and September 2006 were obtained from a specialized thesis, while the subsequent expansion from 2022 to 2023 involved a prospective approach, including an additional 73 patients, resulting in a total of 113 pediatric patients (79 females and 34 males). Comprehensive diagnostic evaluations, such as urinalysis, urine culture, renal function tests, urinary tract ultrasound, uroflowmetry-electromyography (EMG), and post-voiding residual urine measurement (PVR), were conducted. The patient's symptoms were assessed using the Pediatric Lower Urinary Tract Symptom Score (PLUTSS) and a two-day-three-night voiding diary. Results: The correlation between the PLUTSS and VD was not absolute but substantial concerning daytime frequency and incontinence. Notably, PLUTSS emerged as the primary predictor of treatment outcomes. No significant association was discerned between sociodemographic characteristics, such as socioeconomic status, sibling count, toilet training, school performance, patient personality, and LUTD diagnosis or prognosis. Conclusion: The findings underscore the prognostic value of PLUTSS for treatment outcomes in pediatric LUTD. Although a significant correlation was observed between PLUTSS and VD, they are not interchangeable. As a result, concurrent utilization of both tools is endorsed for comprehensive diagnosis, follow-up, and treatment planning in pediatric LUTD.
