Langetermijn follow-up van katheteriseerbare vesicostoma’s bij kinderen, een vergelijking van verschillende technieken

The objective of this study was to compare long-term results of the different techniques used to create continent catheterizable channels (CCC’s) in a single institution. Primary outcomes were revision free survival, stenosis and incontinence. A total of 117 CCC’s were included with median follow-up of 85 months. Surgical revision was required in 52% and laparotomy in 27% of cases. Stenosis requiring revision was seen in 33%. Complete revision was required in eight (7%) cases. A fausse route was formed in 9% of cases. A CCC is an elegant solution for children who experience problems with urethral catheterization. We found no significant differences in outcome between CCC’s from appendix or bladder flap, leading us to conclude that a bladder flap CCC is a good alternative solution if the appendix is not available and bladder volume is sufficient

General anesthesia as a possible GABAergic modulator affects visual processing in children

<p>Gamma-Aminobutyric Acid (GABA) inhibitory interneurons play an important role in visual processing, as is revealed by studies administering drugs in human and monkey adults. Investigating this process in children requires different methodologies, due to ethical considerations. The current study aimed to investigate whether a new method, being general anesthesia using Sevoflurane, can be used to trace the effects of GABAergic modulation on visual brain functioning in children. To this aim, visual processing was investigated in children aged 4-12 years who were scheduled for minor urologic procedures under general anesthesia in day-care treatment. In a visual segmentation task, the difference in Event-Related Potential (ERP) response to homogeneous and textured stimuli was investigated. In addition, psychophysical performance on visual acuity and contrast sensitivity were measured. Results were compared between before and shortly after anesthesia. In two additional studies, effects at 1 day after anesthesia and possible effects of task-repetition were investigated. ERP results showed longer latency and lower amplitude of the Texture Negativity (TN) component shortly after compared to before anesthesia. No effects of anesthesia on psychophysical measurements were found. No effects at 1 day after anesthesia or of repetition were revealed either. These results show that GABAergic modulation through general anesthesia affects ERP reflections of visual segmentation in a similar way in children as benzodiazepine does in adults, but that effects are not permanent. This demonstrates that ERP measurement after anesthesia is a successful method to study effects of GABAergic modulation in children.</p>

Orchidopexy for bilateral undescended testes : a multicentre study on its effects on fertility and comparison of two fixation techniques

To evaluate fertility potential after orchidopexy for bilateral undescended testis and compare two surgical fixation techniques for effect on fertility. Men older than 22 years who had either tunica albuginea orchidopexy (TAO) or “no-touch” technique (NTO) in childhood for bilateral undescended testis (BUDT) were selected. Participants filled out a questionnaire followed by physical examination, had testicular ultrasound, blood sample and semen analysis. Statistical testing was performed using general linear modelling. Sixty-seven out of 166 individuals responded. Forty-nine completed the questionnaire, and nine (18.3%) reported having fathered children. Thirty-six showed up for further examination, 26 had TAO and 10 NTO. Impaired hormonal spermatogenesis regulation (34.6% vs. 20%), higher subfertility rate (46% vs. 20%) and lower means of motile spermatozoa (58.1 × 106 spz vs. 177.9 × 106 spz) were observed in the TAO versus the NTO group; none of these were statistically significant. Four (15.4%) of the TAO and two (20%) of the NTO group have azoospermia. Although the operation technique did not have a significant impact on fertility, unfavourable outcomes were more common after surgery involving the tunica albuginea of the testis. Larger sample sizes are needed to ascertain whether the trends favouring the NTO technique are of any significance

Coping styles in patients with hypospadias

Objective: The objective of this study is to investigate the coping styles used by patients with hypospadias. Long-term hypospadias studies generally show satisfying outcomes, but some report a lower quality of life (QoL) or poorer psychosocial adjustment, particularly in patients with proximal hypospadias. A lower QoL or psychosocial adjustment was found to be associated with passive coping styles in other pediatric patient populations. Hypothetically, patients with hypospadias also develop different coping styles due to medical experiences in childhood, leading to the lower QoL outcomes on the long term. However, coping styles of patients with hypospadias have never been analyzed. Patients and methods: Adult men with hypospadias repair in childhood were recruited (n = 55; aged 19.9 [IQR 19.2–22.1]). Coping styles were determined with the Utrecht Coping List (UCL) and results compared with a reference group of male students (n = 55, age 20–30 years, no medical history). Sub analysis of coping styles of the hypospadias groups was done based on three items: severity of hypospadias, time of last hypospadias surgery and occurrence of postoperative complications. Results: Compared to the reference groups, patients with hypospadias had higher scores on Avoidance (P < 0.05), particularly patients who had ≥1 postoperative complication or proximal hypospadias. Patients with proximal hypospadias also had lower scores on Seeking Social Support compared to the reference group (P < 0.05). Within the hypospadias group, coping style scores did not differ based on severity of hypospadias, timing of surgery or postoperative complications. Conclusion: Patients with hypospadias, particularly those with proximal hypospadias or a postoperative complication, more often use an avoiding coping style compared to a reference population. Attention to coping styles during the follow-up of patients with hypospadias might help to improve the QoL in these patients

Is joint hypermobility associated with vesico-ureteral reflux? An assessment of 50 patients

Study Type – Aetiology (individual cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Recent studies have already shown associations between generalized joint hypermobility (GJH) and voiding and defecation dysfunction and/or slow transit constipation. Changes in extracellular matrix composition in vesico‐ureteric junction of vesico‐ureteral reflux (VUR) patients were also observed previously. This study is the first to assess joint mobility as a parameter for connective tissue composition in vesico‐ureteral reflux. We convincingly demonstrate that VUR patients have significantly more hypermobile joints compared to controls and this provides a new angle to the intriguing subjects of development of VUR and susceptibility to VUR. OBJECTIVE • To assess whether there is an increased prevalence of joint hypermobility in patients with vesico‐ureteric reflux (VUR). MATERIALS AND METHODS • We studied 50 patients with primary VUR and matched controls drawn from a reference population. • Joint mobility was assessed using the Bulbena hypermobility score. RESULTS • We identified significantly more patients with VUR with generalized joint hypermobility than controls (24% vs 6.7%, P= 0.007). CONCLUSION • Our findings confirm our clinical observation of an increased rate of joint hypermobility in patients with VUR. We speculate that an altered composition of the connective tissue may contribute to the severity of the (pre‐existing) VUR phenotype

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

Long-term effect of conservative treatment versus low threshold endoscopic desobstruction on urine incontinence and urgency in boys with persistent overactive bladder symptoms : A cohort study

Aims: To assess the long-term effects of two treatment strategies (low threshold endoscopic desobstruction vs. conservative treatment) on urinary incontinence (UI) and urgency-frequency in boys. Methods: Boys with persistent overactive bladder symptoms treated in two tertiary referral centers between 2006 and 2009 were included. Treatment strategy in center 1 was urethrocystoscopy (UCS) and in case of obstruction urethral desobstruction and in center 2 conservative. The primary outcome was time to being dry during daytime, secondary outcomes were being dry both day and night and presence of urgency-frequency, using the “provisional” International Consultation on Incontinence Questionnaires Children's Lower Urinary Tract Symptoms (LUTS) questionnaire. Results: Median age at start of treatment was 8.0 (IQR 6.4-9.4) years in center 1 and 8.4 (IQR 6.0-10.1) years in center 2. At baseline daytime incontinence was present in 100/104 children (96%, center 1) and 37/44 (84%, center 2). In center 1, UCS was performed in 98 (93%) boys, with desobstruction in 93 (88%), while in center 2 these numbers were 16 (36%), and 5 (11%). There were no differences between groups after a mean follow-up of 5 years concerning dryness at daytime (HR 0.86, 0.56-1.30), dryness day and night (HR 0.72, 0.51-1.14), and presence of urgency-frequency (HR 0.67, 0.38-1.25). Conclusions: The benefit of a strategy including low-threshold UCS and endoscopic desobstruction in boys with urge incontinence and suspected infravesical obstruction to prevent LUTS and incontinence on the longer term could not be confirmed
