The Role of Non-invasive Testing in Evaluation and Diagnosis of Pediatric Lower Urinary Tract Dysfunction
Purpose of Review
The symptoms of lower urinary tract dysfunction (LUTD) including urinary incontinence, frequency, and urgency are among the most common reasons children are referred to pediatric urologists. Despite this, the workup for LUTD is often time consuming and a source of frustration for patients, parents, and clinicians alike. In the current review, we summarize the important role non-invasive testing plays in the diagnosis and management of children with LUTD and to show how use of these tests can help avoid the need for more invasive testing in the majority of children.
Non-invasive tests such urine studies, uroflowmetry ± simultaneous electromyography, assessment of post-void residual, renal/bladder ultrasound, and pelvic ultrasound when used appropriately can provide valuable information to facilitate decision making during the evaluation of children with LUTD. While these tests should be employed prior to more invasive testing such as urodynamic studies, they can often act as a surrogate for the more invasive tests.
Non-invasive tests can help us in our goal of improving diagnostic ability to better classify the child’s LUTD into an actual condition which allows targeted treatment in the hope of better outcomes and more satisfied patients and families.

Evaluation of bladder capacity in children with lower urinary tract symptoms: comparison of 48-hour frequency/volume charts and uroflowmetry measurements. J Pediatr Urol. 2016;12(4):214.e1–5. The authors compare the accuracy of 48 hours frequency/volume charts with uroflowmetery with PVR measurements in children with nocturnal enuresis, overactive bladder and dysfuncitonal voiding. While F/V charts were reliable for children with nocturnal enuresis to estimate maximum bladder capacity, both F/V charts and uroflow/PVR data were neeed for children with OAB and DV to accurately evaluate bladder capacity.

While the DVISS had the highest accuracy in terms of diagnosis of children with LUTS versus controls, all 3 questionnaires showed good correlation with parents’ ratings in terms of response to treatment.

The authors describe the development and utility of a reproducible and reilable method to interprete uroflowmetry patterns called the flow index (FI). Based on data from 1,268 healthy children, FI was tested and shown to be statistically robust in predicting uroflow pattenrs – bell, plateau, and tower. CrossRefPubMedGoogle Scholar

The authors compared a new ultrasound measurement, the ratio of full to empty bladder wall thickness (F/E BWT) in 198 healhty children and 126 children with dysfucntional voiding. F/E BWT ratios were higher in children with dysfunctional voiding compared with healthy children and thus the authors conclude that this ratio may serve as a non-invasive tool for evaluating lower urinary tract symptoms in children.
