Exploring precision risk in pediatric vesicoureteral reflux: Innate immune gene variations and reflux outcomes in the RIVUR cohort.
INTRODUCTION: Children with vesicoureteral reflux (VUR) are at increased risk for morbidity from recurrent urinary tract infections (UTIs), yet the factors influencing spontaneous VUR resolution remain poorly defined. This study evaluates whether genetic variations in key urinary innate immune effectors (DEFA1A3, DMBT1, and RNASE7) influences VUR resolution and interacts with prophylaxis to alter clinical response. METHODS: We conducted a secondary analysis of 303 RIVUR participants with available DEFA1A3 and DMBT1 copy number variation (CNV) data and RNASE7 rs1263872 genotype. Primary outcomes were (1) VUR improvement (decrease in grade) and (2) VUR resolution at study exit. Multivariable logistic regression models included genotype, treatment, and their interactions, adjusting for age, sex, baseline grade (high vs low), laterality, bowel/bladder dysfunction, and any UTI. Internal validation used 2000-sample bootstrap with bias-corrected and accelerated confidence intervals and influence diagnostics. RESULTS: Clinical covariates did not significantly predict VUR improvement. Children with DEFA1A3 CNV >5 had higher odds of improvement (OR 2.36, 95% CI 1.12-4.96, p = 0.023), an effect that remained significant in bootstrap analyses. High-grade VUR was associated with lower odds of resolution (OR 0.34, 95% CI 0.12-0.94, p = 0.038). A significant interaction was observed between prophylaxis and high DMBT1 copy number for VUR resolution (interaction OR 2.99, 95% CI 1.11-8.04, p = 0.031); no interaction was seen for improvement. RNASE7 rs1263872 was not associated with either outcome. CONCLUSION: Innate immune gene variation may contribute to heterogeneity in VUR outcomes. High DEFA1A3 copy number was associated with reflux improvement and a DMBT1-prophylaxis interaction was associated with reflux resolution. The results of this study is hypothesis-generating and prompt further evaluation to assess whether a subset of children may experience structural benefit from prophylaxis or have a more favorable natural history based on their innate immune genotype.

[The spina bifida child with special reference to urologic disease].
From the view of the urological diseases a new conception of the spina bifida cystica is represented. The first part contains informations on etiology, pathological anatomy and physio-pathology. Considering the urological diseases (neurogenic bladder with incontinence and residual urine, vesico ureteric reflux and chronic pyelonephritis) special importance is attached to the pathogenesis. Within the therapeutic methods the treatment with the alpha-blocking agent Phenoxybenzamin (Dibenzyran, Röhm Pharma GmbH, Darmstadt) is emphasized as the actual therapy of the neurogenic bladder. The operative indication of the Ileum-Conduit (Bricker-) is mentioned. An analysis of 125 spina bifida-patients with the pathological findings in the kidneys and the urinary tract is given.

[Cat-eye syndrome. Clinical and cytogenetical differentialdiagnosis (author's transl)].
We report a 5 1/2-year-old girl whose clinical symptoms are consistent with diagnosis of the cat-eye syndrome. The prominent symptoms are: anal stenosis, preauricular tags and pits, coloboma of the iris, doubling of the pelvis and ureter on both sides, vesicourethral reflux on the right side and normal mental development. Leucocyte alkaline phosphatase is normal. Chromosomal analysis shows a supernumerary submetacentric chromosome. This extra chromosome is smaller than the G-group chromosomes and has satellites on the short and long arms. Autoradiography after 3H-thymidine incorporation shows a late-labeling marker chromosome. After using the Giemsa-banding technique, the chromatides demonstrate dark bandings with only soft, unstained satellites. With the fluorescence method, one can see spotlike fluorescence of the satellites on both arms and diffuse fluorescence of the hetero-chromatic segments. In addition, the C-bandings demonstrate a homogeneous dark staining of the chromatids, but we did not find stained satellites. Using the Giemsa-11 technique one can see the 47th chromosome with predominantly heterochromatic parts, but small euchromatic segments are visible between them. Satellites are unstained. Using currently accepted cytogenetical methods, it is not possible to identify the origin of this supernumerary marker chromosome.

Urobiota analysis and genome-wide association study in pediatric recurrent urinary tract infections and vesicoureteral reflux.
Urinary tract infections (UTIs) are the most common severe bacterial infections in young children, often associated with vesicoureteral reflux (VUR). To explore host genetic-microbiota interactions and their clinical implications, we analyzed the urinary microbiota (urobiota) and conducted genome-wide association studies for bacterial abundance traits in pediatric patients with UTI and VUR from the Randomized Intervention for Children with Vesicoureteral Reflux and Careful Urinary Tract Infection Evaluation cohorts. We identified 4 urobiota community types based on relative abundance, characterized by the genera Enterococcus, Prevotella, Pseudomonas, and Escherichia/Shigella, and their associations with VUR, age, and toilet training. Children with VUR exhibited decreased microbial diversity and increased abundance of genera that included opportunistic pathogens, suggesting a disrupted urobiota. We detected genome-wide significant genetic associations with urinary bacterial relative abundances, in or near candidate genes including CXCL12, ABCC1, and ROBO1, which are implicated in urinary tract development and response to infection. We showed that Cxcl12 was induced 12 hours after uropathogenic bacterial infection in mouse bladder. The association with CXCL12 suggests a genetic link between UTI, VUR, and cardiovascular phenotypes later in life. These findings provide the first characterization to our knowledge of host genetic influences on the pediatric urobiota in UTI and VUR, offering insights into the interplay between disease, host genetics, and the urobiota composition.

The future of pediatric vesicoureteral reflux management.
BACKGROUND AND OBJECTIVE: Vesicoureteral reflux (VUR) is a common condition in pediatric urology, yet important uncertainties persist regarding risk stratification, imaging strategies, and prevention of long-term renal damage. Emerging technologies may help address these challenges. This review provides a forward-looking overview of recent advances in artificial intelligence (AI) and immunomodulation that may influence future management of pediatric VUR. METHODS: A forward-looking literature review was performed using the PubMed database (January 2000-March 2025), focusing on studies addressing AI, immunomodulation, or vaccination in the context of VUR and urinary tract infections. Criteria of inclusion were the relevance to pediatric VUR, the novelty of the proposed concept, the potential clinical implications and, for the AI literature, the existence of a clinical evaluation of the algorithm on a dataset from patients. KEY FINDINGS AND LIMITATIONS: AI-based models show promising performance in supporting clinical decision-making, including prediction of the need for voiding cystourethrography, automated grading of VUR, estimation of recurrent urinary tract infection risk and prediction of chemoprophylaxis. These tools may facilitate more individualized diagnostic and therapeutic strategies, although current evidence is largely retrospective and requires prospective validation. Immunization and immunomodulatory approaches aim to reduce infection burden and modulate inflammatory pathways associated with renal scarring. While early experimental and adult clinical data are encouraging, pediatric-specific evidence remains limited, and clinical applicability in children with VUR is not yet established. CONCLUSION: Artificial intelligence and immunologically targeted strategies represent complementary, emerging approaches that may contribute to more personalized management of pediatric VUR. At present, both should be regarded as exploratory tools whose clinical impact will depend on further validation and appropriately designed pediatric studies.

Vesicoureteral reflux and anorectal malformations.
BACKGROUND: Renal and urinary tract anomalies are frequently associated with anorectal malformations (ARMs) and may adversely affect long-term renal outcomes, if not detected early. However, reliable clinical predictors for significant urologic abnormalities across different ARM phenotypes remain poorly defined. OBJECTIVE: To determine the prevalence and grade distribution of vesicoureteric reflux (VUR) in neonates with ARMs, and to explore its association with renal and urinary tract anomalies, the complexity of the ARM phenotype, and other factors are associated with high-grade VUR. METHODS: In this retrospective cross-sectional study, medical records of 64 neonates diagnosed with ARMs and managed at a tertiary children's hospital between 2018 and 2025 were reviewed. All patients underwent renal and urinary tract ultrasonography. Voiding cystourethrography (VCUG) was performed for all neonates according to our institutional protocol, regardless of ultrasound findings or ARM phenotype. Demographic characteristics, ARM phenotype (less-complex vs. complex), urologic findings, urinary tract infection (UTI) history, and associated anomalies were analyzed. Multivariable logistic regression models were used to identify independent predictors of complex ARM phenotype and high-grade VUR. RESULTS: The cohort consisted of 64 neonates (75% male) with a mean gestational age of 37.36 ± 1.83 weeks and a mean birth weight of 2940 ± 601 g. Renal and urinary tract anomalies were common, with hydronephrosis observed in 48.4%, VUR of any grade in 39.1% and hydroureter in 35.9%,of patients. High-grade VUR was identified in 21.9% of patients, and a documented history of UTI was present in 18.8% of the entire cohort. In multivariable analyses, birth weight, presence of VUR, and UTI history were not independently associated with complex ARM phenotype. Additionally, no demographic or clinical variables reliably predicted high-grade VUR. The predictive performance of the regression model for high-grade VUR was limited (AUC = 0.60). CONCLUSION: Renal and urinary tract anomalies are highly prevalent among neonates with ARMs, with VUR representing a prominent finding. The lack of robust clinical predictors for complex ARM phenotype or high-grade VUR underscores the limitations of selective screening strategies and supports the role of comprehensive urologic evaluation in neonates with ARM, regardless of anatomic subtype.

Trio exome sequencing identifies de novo variants in novel candidate genes in 19.62% of CAKUT families.
PURPOSE: Congenital anomalies of the kidney and urinary tract (CAKUT) encompass heterogenous malformations arising from defective nephrogenesis. To date, approximately 50 monogenic genes are known to cause CAKUT if mutated. Recent studies show the impact of de novo variants in genetic disease etiology. Trio exome sequencing identifies de novo variants in novel candidate genes in 19.62% of CAKUT families. METHODS: We performed trio-based exome sequencing in 209 families with CAKUT to detect novel candidate disease genes. RESULTS: Trio analysis yielded in the identification of CAKUT candidate genes in 96 of 209 trio families (45.93%). In 41 of 209 cases, we detected strong de novo variants in 45 potential novel CAKUT candidate genes (19.62%). We developed a prioritization approach that highlights a truncating de novo variant in SOX13 (HGNC:11192) as a promising cause for CAKUT. In addition, further allele carriers for the candidate gene CHD1L (HGNC:1916) were identified, thus supporting the role of CHD1L in the pathogenesis of CAKUT. CONCLUSION: We conclude that de novo variants in potential novel CAKUT candidate genes contribute to the disease etiology and present SOX13 as a potential novel cause for CAKUT.

Operative versus non-operative management of patients with staghorn calculi and neurogenic bladder.
During the last 5 years 22 patients have been treated at our hospital for staghorn calculi and neurogenic bladder. In 17 patients an operation was done soon after discovery of the calculi, while 5 patients were followed non-operatively. The latter 5 patients had a rapid downhill course marked by sepsis and renal function deterioration and an operation was necessary in 4 of the 5 cases. Injudicious non-operative therapy only prolongs the relentless effects of staghorn calculi in patients with spinal cord pathology.

Controlled trial of therapy in covert bacteriuria of childhood.
Sixty-three girls with covert bacteriuria were included in a controlled trial of therapy. Recurrent infection in the treated group was common and was not significantly different from the rate of persistent infection in the untreated control group. Two children in each group developed clinical pyelonephritis; the others have remained healthy and all of them have a normal rate of growth. 2 years after diagnosis three of the thirty-four children in the control group and one of twenty-six children in the treated group have radiological evidence of new scars of pyelonephritis. These changes were relatively minor and in both groups of children renal growth was similar to that in normal children. It is suggested that for most of these children therapy is not essential, and that when renal changes occur they are of little or no significance. Prescriptive screening for cobert bacteriuria of childhood cannot be recommended at present.

The justification for early radiological investigations of urinary-tract infection in children.
97 children, 67 girls aged 0-13 years and 30 boys aged 0-11 years, with apparent first urinary-tract infections were investigated radiologically. The intravenous pyelogram was abnormal in 15.5% of the girls and 33% of the boys and the micturating cystourethrogram was abnormal in 34% of the girls and 39% of the boys. When both examinations were combined the abnormality-rate rose to 41% in the two sexes. Accordingly, radiological investigation of the renal tract is recommended after the first proven urinary tract infection.

Conservative bladder treatment in myelodysplasia. Differentiation of patients by cystomanometry.
Urodynamic evaluation was performed in 75 patients with congenital neuropathic bladder. Concerning treatment the most important parameters were detrusor tone, detrusor activity and bladder outlet resistance. Based on these findings individual conservative therapy was applied. Reflux or dilatation of the upper urinary tract found in 26 children could be controlled by drugs or transurethral operations in 20, urinary diversion had to be done only 4 times. 26 children were selected for intensive treatment of incontinence; in about 50% satisfying urinary control was achieved. These results still need long-term observation. The main interest, however, was to postpone irreversible surgery and to gain time for possible better treatment in the future.

Swimming Upstream to Understand Congenital Anomalies of the Kidney and Urinary Tract: Zebrafish Models for Developmental Biology, Disease Mechanisms, and Functional Interpretation of Genetic Variation.
Congenital anomalies of the kidney and urinary tract (CAKUT) are the leading cause of pediatric chronic kidney disease (CKD) and comprise a heterogeneous group of developmental disorders with a substantial genetic contribution. Advances in next-generation sequencing have facilitated the identification of numerous candidate genes and rare variants associated with CAKUT. However, establishing causality and defining the biological functions of implicated genes remain major challenges. Functional validation is therefore essential to bridge the gap between gene discovery and mechanistic understanding, enabling the interpretation of genetic variation within the context of kidney development and disease. The zebrafish (Danio rerio) has emerged as a powerful in vivo model for studying renal development and interrogating the function of CAKUT-associated genes. Its utility stems from a high degree of genetic and developmental conservation with humans, conserved nephrogenic pathways, optical transparency during embryogenesis, and the relative ease of genetic manipulation. In this review, we provide an overview of zebrafish kidney development within the broader context of vertebrate nephrogenesis, highlighting the key genetic programs governing intermediate mesoderm specification, nephron segmentation, and pronephric morphogenesis. We then systematically examine CAKUT-associated genes that have been modeled in zebrafish, focusing on studies that have linked genetic perturbations to renal development and structural phenotypes. Finally, we discuss the strengths and limitations of zebrafish models for functional genomics and variant interpretation and consider their emerging role in bridging genetic discovery with mechanistic insights into CAKUT pathogenesis.

[Urologic symptoms in the abdominal muscle deficiency syndrome (author's transl)].
The abdominal muscle deficiency syndrome ("prune belly syndrome"(, a symptom triad of aplasia of the abdominal wall musculature, malformations of the urinary tract, and cryptorchism, is described from the urologist's point of view, citing nine cases. With modern diagnostic procedures the early detection of the correct diagnosis in the usually very young patients is possible. While the urologic symptomatology is due to the malformations in the urinary tract, the life expectancy depends mainly on the degree of renal function impairment. Combat of infection together with proper operative repairs are the treatments of choice to date. Instrumental procedures should be limited as much as possible. The survival changes following kidney transplantation appear promising.
