RESUMEN
OBJECTIVES: To compare postnatal outcomes of AUV and PUV patients to evaluate for potential differences between these conditions, given that anterior urethral valves (AUV) with or without concomitant posterior urethral valves (PUV) is a rare congenital anomaly leading to lower urinary tract obstruction (LUTO). METHODS: We reviewed our LUTO database and included patients with AUV or concomitant AUV+PUV, managed at our institution between 2003 and 2023 matching them to comparable PUV cases. Assessed variables included prenatal diagnosis, gestational age (GA) at birth, initial management, kidney function, presence and degree of hydronephrosis (HN), and need for renal replacement therapy (RRT). RESULTS: The AUV ± PUV group (AUV: n=11, concomitant PUV: n=2) and PUV group (n=26) had similar presenting ages and follow-up times (p>0.05). Only 15.4% of AUV cases presented prenatally compared to 72.0% of PUV cases (p=0.0016), leading to delayed postnatal management in AUV patients (p=0.0260). Findings at presentation included UTI, weak stream or a palpable penile mass. PUV patients demonstrated significantly higher creatinine levels at the initial visit and at last follow-up (p=0.0120 and p=0.0302) than the AUV ± PUV group, with only one patient requiring RRT (p>0.05). At the last follow-up, no patient in the AUV ± PUV group required clean intermittent catheterization compared to 37.5% in the PUV group (p=0.0331) which also demonstrated more patients with persistent HN (p=0.0039). CONCLUSION: AUV with or without concomitant PUV is a rare finding that should be considered in patients presenting with weak stream, UTI, and penile swelling. Our data suggests potential differences in presentation and less severe postnatal outcomes in AUV compared to PUV patients.
RESUMEN
Obese people are mostly unable to maintain successful weight loss after the end of a dietary change. One reason is that conventional weight reduction concepts neglect physiological hunger and satiety perception, leading to a relapse to previous eating habits on the long run. We examined the long-term efficacy of a psychological smartphone weight loss program, which avoids any dietary instructions and aims at relearning of satiety perception. Parameters of body weight alterations and psychological features, for example, satiety perception, food cravings, and emotional eating, were explored in a nonrandomized experimental study comprising 75 obese participants. Measurements occurred at baseline, two times during program application, as well as at 6- and 12-month follow-up. Participants displayed significant weight loss during the entire study period (p = .029) and showed an improved body composition at the 6-month follow-up (p = .018). These effects were associated with increased satiety perception, as well as reduced food cravings, and emotional eating habits. Notably, all improvements in measured parameters significantly sustained between the end of the program and the 12-month follow-up (p < .005 for all). Psychological relearning of satiety perception may outclass dietary approaches in terms of long-term efficiency.

INTRODUCTION: Posterior urethral valves (PUV) is a chronic condition that can adversely impact child and family health related quality of life (HRQOL). Surprisingly, to date, the impact of this condition on the QOL of children with PUV has not been studied. Thus, our aim is to evaluate this important aspect of care using validated questionnaires in our institutional PUV clinic. METHODS: From December 2022 to January 2024, the PedsQL Inventory and associated family impact module was distributed in our PUV clinic. Higher scores reflect better HRQoL and less impact on family. Children >8 years old completed the tool themselves, otherwise parents completed the tools on behalf of the child. We compared PUV scores against reported psychometric data from healthy children and other chronic illnesses. RESULTS: A total of 112 families completed the questionnaires. The total HRQoL score was 80 ± 13. Overall, we noted that the domains reflecting psychosocial impact were significantly lower than those of physical well-being (76 ± 16 vs. 89 ± 15 for psychosocial and physical impact, respectively; p < 0.01). There was a significant difference in the psychosocial emotional impact for children managed with clean intermittent catheterization (CIC) compared to those who were not (69 ± 21 vs. 81 ± 16; p = 0.005) (Table 2). In addition, we noted that children with PUV scored similar to healthy controls, but higher than children with other chronic illnesses. With respect to the impact on family, overall, parent, and family impacts were 76 ± 19, 78 ± 21, and 81 ± 21, respectively. DISCUSSION: Chronic illness has been associated with a negative impact on HRQoL in both adults and children. We noted similar findings the present study, particularly for young children and those who are maintained on CIC. To our knowledge, this is the first study to evaluate the impact of PUV on a child's HRQoL as well as the impact on the family, and to document a negative psychosocial impact of CIC in this population. However, there are some important limitations to be addressed including relying on families to complete questionnaires accurately during busy clinic visits and the lack of controls from the same environment. CONCLUSION: When compared to healthy controls, PUV patients score similarly in HRQoL assessment. In addition, children <3years of age report a negative impact on physical well being, and CIC negatively impacts the emotional well-being. These data can be used to advocate for better mental health supports and social work for these children.

BACKGROUND: Little is known about alpha blocker use in young children, particularly in those with lower urinary tract obstruction (LUTO). Therefore, we aimed to assess the safety and tolerability of selective alpha-blockers in children under 3 years of age with LUTO. METHODS: A prospectively-collected database captured 93 patients born between 12/2005 and 01/2023. Assessed data included baseline characteristics, ultrasound features, blood pressure (BP), side effects and creatinine values. Primary outcome was side effects or discontinuation of alpha-blockers. Secondary outcomes were BP parameters, growth, and kidney function. Data are shown as median with interquartile range (IQR), Odds Ratio (OR) with 95% CI and mean value with standard deviation (SD). RESULTS: A total of 33 patients less than 3 years of age were started on alpha-blockers at 16.8 ± 11.8 months and followed for 48.9 ± 40.5 months. At last follow-up, no significant effect on systolic/diastolic BP percentiles (p > 0.9 and p > 0.9), creatinine levels (p > 0.9). Weight percentiles increased to the last follow-up (37.8 ± 33.2 vs. 53.6 ± 32.9, p = 0.0133) while height percentiles increased from 28 to 100 days to last follow-up (12.9 ± 18.3 vs. 39.6 ± 35.2, p=0.001). Four patients discontinued alpha-blockers; however, no side-effects were reported during the study period. CONCLUSIONS: No severe clinical or systemic side effects were observed, demonstrating safety and tolerability in young children with LUTO. Although alpha-blockers did not significantly improve kidney function in short term follow-up, and failure to thrive was not observed in these children. Additional studies with more patients are required to assess the optimal dosing and timing leading to maximal benefits for these infants.

PURPOSE: We describe long-term outcomes, including UTIs and need for reimplantation, after ureterovesicostomy (UV) as a lasting surgical procedure for children with primary obstructive megaureter (POM). MATERIALS AND METHODS: Children referred to our institution between 2016 and 2023 who underwent refluxing UV were analyzed. POM was defined as hydroureteronephrosis with distal ureteral dilatation > 7 mm and a negative workup for other etiologies of hydronephrosis. We assessed for surgical outcomes, complications, rate of UTI, and improvement in upper tract dilatation. Statistical analyses assessed for change in hydronephrosis metrics over follow-up. RESULTS: Among 183 patients diagnosed with POM, 47 (24%) underwent UV. Median age of presentation, surgery, and follow-up was 2, 9, and 43 months, respectively. A total of 7 patients developed 30-day complications: Clavien-Dindo grade 1 in 2 (transient urinary retention) and grade 2 in 5 (UTIs). During monitoring 14 (30%) developed UTIs and 7 (15%) required ureteral reimplant or UV takedown. After surgery there was a significant decrease in the proportion of patients with high-grade hydronephrosis, anteroposterior renal pelvis diameter, and maximum ureteral dilatation. CONCLUSIONS: Refluxing UV is a safe alternative to cutaneous diversion in POM. Most patients had improvement in upper tract dilatation with an acceptable short-term complication rate and need for reoperation (in comparison to routine later reimplantation). Our experience suggests that monitoring alone after UV is feasible, and that selective subsequent reconstruction is a reasonable strategy.

INTRODUCTION: The morphology of the bladder and posterior urethra on initial voiding cystourethrogram (VCUG) in posterior urethral valve (PUV) has been proposed as a meaningful early metric for short- and long-term kidney outcomes. Here, we seek to externally validate the proposed association and assess the reliability of PUV morphology characteristics. MATERIALS AND METHODS: We reviewed our institutional database for patients managed for PUV between 2000 and 2022 and included those treated with primary ablation with at least 1 year of follow-up for kidney function. Each VCUG was evaluated by three independent raters for the height-width ratio of the bladder (HW-B), height-width ratio of the posterior urethra (HW-PU), and posterior-anterior urethral ratio (PA-UR), and trabeculation (none, fine, or coarse). We assessed the reliability in these with intra-class coefficient and Fleiss kappa for continuous and categorical data, respectively. We performed univariate analysis with nadir creatinine and five-year follow-up glomerular filtration rate (GFR). RESULTS: In total, 98 patients met inclusion criteria. The median age at diagnosis and ablation was 10 and 21 days, respectively. Patients with nadir creatinine <0.8 mg/dL had higher follow-up GFR (101 vs. 20 ml/min/1.73 m2, p = 0.04), and lower risk of CKD (odds ratio 14.7, p = 0.002). The median value for HW-B was 1.4, median HW-PU was 2.1, and median PA-U was 4.7, There was significant inter-class agreement between all three measures of 0.80, 0.51, and 0.70 (p < 0.001). The inter-rater agreement for bladder trabeculation was fair (Fleiss K = 0.40, p < 0.001). There was no statistically significant correlation between HW-B, HW-PU, PU-A with nadir creatinine (p = 0.07, 0.33, 0.91) or 5-year GFR (0.27, 0.45, 0.62), respectively. DISCUSSION: There is significant interest in determining prognostic factors and metrics in PUV. The morphological characteristics on VCUG are reliable and is available information for all boys diagnosed with PUV, resulting in an attractive metric. While we do not demonstrate correlation with kidney outcomes, VCUG features warrant further attention as prognostic factors in PUV. CONCLUSIONS: PUV morphology on initial VCUG is a reliable metric of lower urinary tract deformity but is not associated with 5-year kidney outcomes.
