Dysfunctional Voiding: Exploring Disease Transition From Childhood to Adulthood

OBJECTIVE

To improve our transitional care, we explored how childhood dysfunctional voiding (DV) develops into adulthood. DV is a common condition in both children and adults. However, the long-term course of childhood DV into adulthood is unknown and treatment over the ages differs.

METHODS

A cross-sectional follow-up was performed in a cohort of 123 females treated from 2000 to 2003 for childhood DV with urinary tract infections (UTIs) and/or daytime urinary incontinence (DUI). The main outcome was a staccato or intermittent urinary flow pattern, possibly indicating persistent or recurred DV according to the International Continence Society criteria. Flow patterns of healthy women were used to compare results.

RESULTS

Twenty-five patients participated in this study, with a mean duration of 20.8 years after urotherapy. In 10/25 (40%) cases, a staccato or interrupted urinary flow pattern was found on the current measurement, compared to 5/47 (10.6%) in the control group. Around 50% (5/10) of the patients with a dysfunctional flow pattern reported UTIs and 50% (5/10) experienced DUI. In the group with a normal flow pattern, 2/15 (13%) reported UTIs and 9/15 (60%) DUI. The impact of DUI on quality of life was moderate to high in both groups.

CONCLUSION

Our results show that 40% of females who had extensive urotherapy for DV in childhood, still have DV according to International Continence Society criteria as an adult, 56% still experience DUI, and 28% UTIs. These data should be taken into account in the counseling of patients and for guiding the process of transition into adulthood.

The effect of meatal correction on daytime urinary incontinence in girls with an anterior deflected urinary stream

INTRODUCTION

Girls with an anterior deflected urinary stream (ADUS) are known to wet the toilet rim and their buttocks while voiding. This deviation may prevent adopting an ideal toileting position and can thus develop into a functional voiding disorder. Although surgical correction of the urinary stream by a meatotomy is part of standard care in girls with ADUS and lower urinary tract symptoms (LUTS) at our center, little is known about the effect of this procedure on daytime urinary incontinence (DUI).

OBJECTIVE

To assess the effect of meatal correction on incontinence in girls with ADUS and DUI, and to find predictors for therapy success.

STUDY DESIGN

A retrospective chart study including all girls with ADUS and DUI who underwent a dorsally directed meatal correction at our tertiary referral center between 2005 and 2018 (n = 274). The main outcome measurement was continence according to the International Children's Continence Society criteria, expressed as the percentage of children that were continent at post-surgical follow-up (complete response). Multivariate logistic regression was used to identify predictors of continence.

RESULTS

In 93% of girls, the direction of the urinary stream was no longer anterior deflected. 29% (n=79) of all girls were continent at post-surgical follow-up. We could not find a convincing predicting factor for achieving continence.

DISCUSSION

Although meatal correction is successful on normalizing the direction of the urinary stream, less than one-third of girls became continent. In addition, we were unable to indicate which girls will profit from this procedure in terms of continence. Since not every girl with ADUS develops incontinence complaints, it may also be questionable whether ADUS and incontinence are directly related. Since other, less invasive and more effective treatment options for DUI are available, meatal correction should therefore be considered a last-resort option in the treatment of pediatric DUI in girls with ADUS.

CONCLUSION

Of the 274 girls with ADUS and DUI, 29% did benefit from a meatotomy. No convincing indicator for therapy success could however be found. Therefore, we discourage a meatotomy as standard treatment in girls with ADUS and DUI.

Pelvic floor rehabilitation in children with functional LUTD: does it improve outcome?

INTRODUCTION

If children do not experience satisfactory relief of lower urinary tract dysfunction (LUTD) complaints after standard urotherapy is provided, other treatment options need to be explored. To date, little is known about the clinical value of pelvic floor rehabilitation in the treatment of functional voiding disorders.

OBJECTIVE

Therefore, we compared pelvic floor rehabilitation by biofeedback with anal balloon expulsion (BABE) to intensive urotherapy in the treatment of children with inadequate pelvic floor control and functional LUTD.

STUDY DESIGN

A retrospective chart study was conducted on children with functional incontinence and inadequate pelvic floor control. All children referred for both intensive inpatient urotherapy and pelvic floor rehabilitation between 2010 and 2018 were considered for inclusion. A total of 52 patients were eligible with 25 children in the group who received BABE before inpatient urotherapy, and 27 children in the group who received BABE subsequently to urotherapy. Main outcome measurement was treatment success according to International Children's Continence Society criteria measured after treatment rounds and follow-up.

RESULTS

Baseline characteristics demonstrate no major differences between the BABE and control group. There was a significant difference in improvement between BABE and inpatient urotherapy after the first and second round of treatment (round 1: BABE vs urotherapy; 12% vs 70%, respectively, round 2: urotherapy vs BABE; 92% vs 34%, respectively, both P < .001). In both cases, the urotherapy group obtained greater results (Fig. 1). When the additional effect of BABE on urotherapy treatment is assessed, no significant difference is found (P = .355) in the children who received BABE; 30 (58%) showed improvement on pelvic floor control.

DISCUSSION

Our findings imply that training pelvic floor control in combination with inpatient urotherapy does not influence treatment effectiveness on incontinence. Intensive urotherapy contains biofeedback by real-time uroflowmetry; children receive direct feedback on their voiding behaviour. Attention offered to the child and achieving cognitive maturity with corresponding behaviour is of paramount importance. It is known that combining several kinds of biofeedback does not enhance the outcome. However, our results do not provide a conclusive answer to the effectiveness of pelvic floor physical therapy in the treatment of children with LUTD because we specifically investigated BABE.

CONCLUSION

In this study, we could not prove that pelvic floor rehabilitation by BABE has an additional effect on inpatient urotherapy on incontinence outcomes. Considering the invasive nature of BABE, the use of BABE to obtain continence should therefore be discouraged.

The Engagement of the Pelvic Floor Muscles to the Urethra, Does Variation in Point of Action Exist?

Purpose: Lower urinary tract dysfunction (LUTD) occurs frequently in girls and may display a spinning top urethra (STU) on voiding cysto-urethrogram (VCUG) in case of dysfunctional voiding. A STU presents as a narrowing of the urethra caused by a lack of relaxation of the pelvic floor musculature during micturition and may vary in length between the proximal and the distal urethra. Although a STU has been recognized since 1960 as a pathological entity on VCUG, no reports exist on the different levels of engagement of the pelvic floor muscles to the urethra as expressed by the varying length of the phenomenon. The aim of our study is to demonstrate the wide anatomical variation in the level of engagement of the pelvic floor musculature to the urethra. Materials and Methods: Dynamic ultrasound videos of pelvic floor musculature of 40 girls with LUTD were reassessed by three observers, looking for the level of engagement of the puborectalis muscle (PRM) to the urethra during coughing, Valsalva and hold-up maneuver. Three levels were defined, for the level of engagement of the pelvic floor to the urethra, proximal, mid, and distal. Intra- and inter-rater variability was analyzed using Cohen's kappa statistics. Results: A wide range of points of action was found on the assessed ultrasound videos. Intra- and inter-rater agreement showed different levels of conformity, varying over a wide spectrum (intra-rater kappa 0.145-0.546; inter-rater kappa -0.1030.724). Throughout the assessed videos, all not-corresponding intra-rater observations differed maximal one category. Of the not-corresponding inter-rater observations, 90% differed maximal one category. Conclusion: An anatomical variation in levels of engagement of the PRM to the urethra does exist. The clinical value of this finding, whether the point of engagement influences symptomatology or treatment success of LUTD, is currently being studied.
