PURPOSE

Lifting and waking are described as waking the children from sleep and taking them to the bathroom to pass urine. Traditionally these methods have been used by families to manage bedwetting. The aim of this study is to examine the relationship between the lifting and waking methods used by families and pelvic floor muscle activity in children with primary monosymptomatic nocturnal enuresis (PMNE).

MATERIAL AND METHODS

A total 48 voluntary children with PMNE and their families were included. The families were questioned about the presence of night lifting and the frequency of night lifting. Pelvic floor muscle findings were measured externally with the Modified Oxford Scale and superficial electromyography. Mean contraction and relaxation values were recorded in a 50-second measurement, which included 5 seconds of contraction and 5 seconds of relaxation with EMG.

RESULTS

It was noted that 41 of 48 families (85%) lifted their child with PMNE to urinate at night, while 7 families (14%) did not. The frequency of lifting during the night was found 1.95± 1.09 (Mean± SD). There was a positive correlation between the frequency of night lifting and the mean relaxation value of pelvic floor muscle (p<0.05), there was no correlation between the Modified Oxford Scale and the mean contraction value (p>0.05).

CONCLUSIONS

Lifting and waking can cause unwelcome results. Sleepy micturition may block the child from waking up when the bladder is full and micturating in a controlled manner. According to our findings, lifting and waking have a negative effect on pelvic floor relaxation of children.

PURPOSE

Bladder volumes(BV) estimation with automated bladder scanner(BS) is integral to assessment of Lower Urinary Tract dysfunction in nurse-led clinics. We observed high Post Void Residual recordings (PVR) with Bladdder Scanner in children where standard ultrasound scan (US) had shown satisfactory emptying. Automated BS are designed to look for fluid and when there is minimal PVR, it tends to pick up other fluid-filled structures such as bowel loops or artefacts caused by bowel gas. Thus, we designed a multicentre prospective observational study comparing BS volumes with US volumes.

MATERIAL AND METHODS

Four centres participated. Pre and post-void BV were measured in patients attending for abdominal ultrasonography in radiology departments using both BS and US. Patients with known abnormal shaped bladders were excluded.

RESULTS

Ninety-nine patients (52% female, mean age of 9.2 years(range: 2-17 years)) were included.

Pre-void BS volumes ranged from 1-734mls(median: 126mls) and US from 5-653mls(median: 121mls). The intraclass correlation coefficient (ICC) was high(0.88 (p<0.001)), indicating that measurements were concordant suggesting high degree of reliability.

Post-void BS volumes ranged from 0-153mls(median: 18mls) and US from 0-74mls(median: 7mls). The ICC was lower(0.46 (p<0.001)), indicating that the measurements were discordant and reliability was poor.

CONCLUSIONS

BS and US have high concordance when the bladder is full but poor discordance on PVR assessment,with the BS giving a false high volume due to wrong interpretation of artefacts as fluid signal. This will lead to false assessment of emptying ability and should be kept in mind when making management decisions based on PVR assessments by BS.

INTRODUCTION

This case report describes  adjustments  in urotherapy program treatment taking into account the patient's age, autism spectrum disorder, anxiety  as well as his emotional development.

CASE DISCRIPTION

An 11-year-old boy was referred to a third line center with refractory day- and nighttime incontinence (daily), urgency and diagnosed with an overactive bladder.

The standard program was personalized  in cooperation with the parents, teachers and healthcare professionals who are involved in the boy.

Some examples of  adjustments we made are:

A shift from the clinical program to a training in his safe and predictable home environment. Adding pictograms to the daily training schedule. Furthermore preparations  and additional visits to the urotherapist were necessary to prepare  the patient.  Use of a timer watch to teach timed voiding and he wore an alarm pants for 5 days. Extending the training program to reinforce learned skills. There was regularly coaching, by telephone, email and in the outpatient clinic.

OUTCOMES

Daytime incontinence reduced from daily to once a week. He urinates at set times, however he remains dependent on the timer watch. Independence of patient was increased thus giving psychological relief to him and the family

DISCUSSION

The outcome demonstrates that customized care takes time and requires a focused commitment and time investment from everyone.

EVALUATION OF THE ADDITIONAL EFFECT OF CONTINUOUS ULTRASOUND BLADDER MONITORING IN UROTHERAPY FOR CHILDREN WITH FUNCTIONAL DAYTIME URINARY INCONTINENCE. STUDY PROTOCOL FOR A PARALLEL-GROUP RANDOMIZED CONTROLLED MULTI-CENTER TRIAL (THE SENS-U TRIAL).

PURPOSE

Urotherapy is the first treatment of choice for functional daytime urinary incontinence (DUI) in children. Alarm therapy can be a part of urotherapy as it provides the child adequate feedback on wetting accidents. Current alarm systems notify either at a set interval or give a notification when wetting has already occurred to prompt the child to go to the toilet. These alarms do not teach the child the interpretation of the bladder sensation preceding wetting accidents. A new wearable bladder sensor, the SENS-U, recently became available. This is a relative small, wireless ultrasonic sensor, which continuously monitors bladder filling. The SENS-U is able to provide an alarm at the exact moment voiding is warranted. It facilitates the child to learn the sensation of bladder filling preceding voiding in an easier way, increasing the learning curve throughout treatment. Its additional effect in urotherapy on continence and cost-effectiveness is to be determined.

MATERIAL AND METHODS

This is a multicenter clinical superiority parallel-group randomized controlled trial including a total of 480 children. Participants between 6-16 years of age with functional DUI in which urotherapy is offered as the next treatment of choice, are eligible. Four centers, two academic hospitals and two general care (peripheral) centers are participating. Participants will be randomized at a 1:1:1 ratio into three groups; urotherapy (care as usual), urotherapy with the SENS-U added for 3 consecutive weeks throughout the training or urotherapy with a SHAM device for 3 weeks.

RESULTS

 The primary outcome is number of wetting accidents per week after 3 months of training, compared between the SENS-U and the SHAM-device. The magnitude of the placebo effect will be assessed by comparing the results of the SHAM group versus the control group.

CONCLUSIONS

To our knowledge, this is the first trial studying not only the effect but also the cost-effectiveness of alarm interventions as commonly added in urotherapy.
