Pediatr Nephrol 2023; 38:771-779. [PMID: 35748940 DOI: 10.1007/s00467-022-05645-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 05/11/2022] [Accepted: 05/27/2022] [Indexed: 01/19/2023]
Abstract
BACKGROUND Nocturnal polyuria (NP) due to a suppressed vasopressin circadian rhythm is a well-documented pathogenetic mechanism in enuresis, mainly studied in monosymptomatic enuresis. A substantial percentage of patients do not respond to desmopressin. This suggests that NP may not only be related to vasopressin, but that other kidney components play a role. Solute handling and osmotic excretion have been investigated in the past, especially in refractory patients. Nevertheless, data in treatment-naïve populations with information on timing overnight are sparse. This study aims to investigate the diuresis and solute excretion in treatment-naïve patients with or without NP, with emphasis on circadian rhythms. METHODS Retrospective analysis of 403 treatment-naïve children 5-18 years with severe enuresis (> 8 nights/2 weeks). Circadian rhythms were evaluated by a 24-h urine collection in 8 timed portions (4 day, 4 nighttime) at in-home settings. Urine volume, osmolality, and creatinine were measured. Patients were subdivided into three groups according to nocturnal diuresis (ND) and Expected Bladder Capacity (EBCage) ratio: (a) < 100%, (b) 100-129%, (c) > 130%. RESULTS All groups maintained circadian rhythm for diuresis and diuresis rates. Patients with higher ND (100-129% and > 130% EBCage) had higher daytime volumes and less pronounced circadian rhythm. In the ND group > 130% EBCage, the ND rate was higher during the first night collection and osmotic excretion was significantly higher overnight. CONCLUSIONS Overall 24-h fluid intake (reflected by 24-h diuresis) and nutritional intake (24-h osmotic excretion) might play a role in enuresis. Increased diuresis rate early in the night can be important in some patients, whereas the total night volume can be important in others. A higher resolution version of the Graphical abstract is available as Supplementary Information.

Abstract
BACKGROUND AND AIM Two central problems with the enuresis alarm are the family workload and the lack of predictors of therapy response. We wanted to look at predictors of alarm response in a setting reflecting clinical reality. METHODS An alarm linked to a smartphone app was provided to enuretic children managed at pediatric outpatient wards. Baseline data (sex, age, daytime incontinence, urgency, previous therapies, arousal thresholds and baseline enuresis frequency) were recorded. Further information, such as enuretic episodes and actual alarm use, was gathered via the app during therapy. Therapy was given for 8-12 weeks or until 14 consecutive dry nights had been achieved. RESULTS For the 196 recruited children the outcome was as follows: full responders (FR) 18.4%, partial responders (PR) 20.4%, nonresponders (NR) 22.4% and dropouts 38.8%. We found no clear predictors of response or adherence among baseline data. But as treatment progressed responders reduced their enuresis frequency as compared to NR (week two P = 0.003, week three and onwards P < 0.001). This is further illustrated in the Figure below. Furthermore, the children unable to complete the full treatment had more non-registered nights already from the second week (week two P = 0.005, week three P = 0.002 and so on). DISCUSSION Anamnestic data give little predictive information regarding enuresis alarm response or adherence. Contrary to common belief neither daytime incontinence nor previous alarm attempts influenced treatment success. But after 2-4 weeks of therapy the children with a good chance of treatment success could be discerned by decreasing enuresis frequency, and the families that would not be able to comply with the full treatment showed incomplete adherence already during the first weeks. CONCLUSIONS Maybe the enuresis alarm strategy should be changed so that the treatment is reassessed after one month and only children with a high chance of success continue. This way, unnecessary frustration for the families of therapy-resistant children may be reduced.

Abstract
LUTD is one of the possible factors influencing pediatric kidney graft outcomes. This study evaluates the results of a thorough assessment of voiding behavior in pediatric transplants. Data of patients with kidney disease of nephrological origin are compared to those with urological origin. A single-center analysis of pediatric kidney transplants performed from 2005 to the present was executed. Donor and recipient characteristics as well as voiding and drinking habits were documented using FVCs and uroflowmetry with PVR measurements. LUTD was defined by a mean MVV >150% or <65% of the EBC for age, abnormal uroflowmetry, PVR repeatedly >15% of EBC or >20 mL, abnormal voiding patterns or behavior, and presence of LUT symptoms. LUTD was diagnosed in 71% of the 56 screened children and more present in urological origin of kidney disease (100%) compared to nephrological origin (61%, P = .005). Individual presence of LUT symptoms, abnormal voiding behavior, FVC parameters, UTIs, and uroflowmetry/PVR parameters were not different between the two groups. Polyuria after transplantation was seen in 63% of patients, mainly in the first post-transplant years and recipients aged <10 years. Time after transplantation was a significant independent predictive factor for the presence of LUTD. LUTD is common in all pediatric kidney recipients and underestimated in those with a nephrological origin of disease. Active screening, monitoring and a care attention plan prior to transplantation and during follow-up, is advocated to optimize outcomes for all patients.

Abstract
INTRODUCTION The case history is the primary tool when investigating the enuretic child. To further determine whether nocturnal polyuria or detrusor overactivity is present, a full voiding chart, is the method of choice. However, there is no robust evidence that daytime voiding chart data actually do predict nocturnal detrusor function. AIM The aim of this study was to assess the predictive value of anamnestic data and the voiding chart in the treatment of children with therapy-resistant enuresis. PATIENTS AND METHODS The patients all suffered from enuresis resistant to first-line therapy. None of the children had daytime incontinence. In accordance with international recommendations, the children were first treated with anticholinergics. If the therapeutic effect was not satisfactory dosage was adjusted and desmopressin was added. If sufficient treatment effect was not achieved, antidepressant therapy was tried next, combined with desmopressin if needed. Since this was an evaluation of clinical practice, not a randomized trial, treatment success was graded according to family satisfaction, not the actual frequency of wet nights. Thus, only children who reported that they were completely dry were regarded as full responders and those who stated that there was a substantial and useful reduction of wet nights were labeled intermediate responders. RESULTS In total, 154 patients were included. Few and inconsistent differences were found between the groups responding or not responding to the various treatment regimens, and this was true both for anamnestic and voiding chart data (see Table). The only statistically significant findings were that responders to antidepressant therapy were older (p = 0.013) than non-responders, and patients who benefited from addition of desmopressin had a higher micturition frequency than those who did not (p = 0.027). The children who needed desmopressin as part of combination treatment to become dry did not have significantly higher nocturnal urine production than those who had no such benefit (p = 0.619). Neither the presence of urgency nor a history of previous daytime incontinence was significantly more common in children responding to anticholinergics (p = 0.375 and 0.072, respectively). DISCUSSION No clear and consistent differences in either anamnestic factors or voiding chart data were found between the patients responding or not responding to the various treatment regimens. Not even urgency could predict anticholinergic efficacy. Somewhat surprisingly, no association between nocturnal polyuria and desmopressin benefit was found. CONCLUSION In this study no prognostic value was found in anamnestic or voiding chart data in children with therapy resistant enuresis.

SENS-U: continuous home monitoring of natural nocturnal bladder filling in children with nocturnal enuresis - a feasibility study. J Pediatr Urol 2020; 16:196.e1-196.e6. [PMID: 32160977 DOI: 10.1016/j.jpurol.2020.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Accepted: 01/07/2020] [Indexed: 10/25/2022]
Abstract
INTRODUCTION Enuresis is a common problem in children. One treatment option is a wetting alarm that provides an alarm when incontinence occurs. A drawback of this approach is that the child is still awakened by wet sheets. Recently, a wearable, wireless ultrasonic bladder sensor became available, the SENS-U, which has the potential to prevent the enuretic event by waking up the child before the bladder is full. In this first feasibility study, the aim is to perform a night-time, home-based evaluation of the SENS-U in children with monosymptomatic nocturnal enuresis (MNE). PATIENTS AND METHODS In this study, children (6-12 years) with MNE were included for a one-night monitoring session. During the night, the SENS-U continuously (i.e. every 30 s) estimated the filling status [notifications were deactivated]. In addition, urine volume was collected in a measurement cup (or diaper weight). The total measured natural nocturnal bladder filling (NNBF) cycles was analyzed by descriptive statistics. Before and after the measurement, sleep behavior was assessed by a selection of the Children's Sleep Habits Questionnaire. RESULTS Fifteen patients (boys/girls: 13/2) [mean age: 8.6 ± 1.5 years] have been enrolled. One patient was excluded due to inadequate sensor-to-skin contact. For 14 children, 18 NNBF cycles were recorded (voiding diary) of which three patients (21%) had more than one NNBF cycle. The SENS-U was able to successfully detect 83% of the NNBF cycles. The three missed NNBF cycles had a voided volume ≤30 ml, which was at the lower limit of the sensor's detection range. The SENS-U had no effect on sleeping behavior. CONCLUSION The SENS-U was able to monitor the natural nocturnal bladder filling successfully in children with monosymptomatic nocturnal enuresis at home, without disturbing their sleep. Future research focuses on investigating the usability of the SENS-U for both diagnostic - and treatment purposes.
