Abstract
PURPOSE OF REVIEW Although pediatric psychology is heavily involved in many medical divisions, its involvement in a urology division is still relatively new and its role continuously evolving and growing. RECENT FINDINGS This article reviews the limited research on the use of psychology in a urology division, including psychosocial struggles across urology diagnoses, dysfunctional voiding, and anxiety surrounding medical procedures and surgery. Urinary diagnoses and presenting problems seen by pediatric psychologists and medical providers at an urban children's hospital are also included. Based on the complex conditions and varied presenting concerns in a urology division, potential assessments and future research are suggested to help gather data for this population moving forward and expand the literature on urology psychology.

Abstract
BACKGROUND The landscape of available psychosocial services within pediatric nephrology care is poorly characterized. However, the effects of kidney disease on emotional health and health-related quality of life are well documented, as is the impact of social determinants of health on kidney disease outcomes. The objectives of this study were to assess pediatric nephrologists' perceptions of available psychosocial services and to elucidate inequities in access to psychosocial care. METHODS A web-based survey was distributed to members of the Pediatric Nephrology Research Consortium (PNRC). Quantitative analyses were performed. RESULTS We received responses from 49 of the 90 PNRC centers. With regards to dedicated services, social work was most commonly available (45.5-100%), followed by pediatric psychology (0-57.1%) and neuropsychology (0-14.3%), with no centers having embedded psychiatry. Availability of psychosocial providers was positively associated with nephrology division size, such that as center size increased, access to various psychosocial providers increased. Notably, the majority of respondents indicated that perceived need for psychosocial support exceeds that which is currently available, even at centers with higher levels of current support. CONCLUSIONS Within the US, there is wide variability in the availability of psychosocial services within pediatric nephrology centers despite a well-documented necessity for the provision of holistic care. Much work remains to better understand the variation in funding for psychosocial services and in utilization of psychosocial professionals in the pediatric nephrology clinic, and to inform key best practices for addressing the psychosocial needs of patients with kidney disease.

Abstract
BACKGROUND Prune belly syndrome (PBS), also known as Eagle-Barrett syndrome (EGBRS), is a rare congenital disease characterized by deficiency or absence of abdominal wall muscles, urological abnormalities, and bilateral cryptorchidism. TYPES OF STUDIES REVIEWED A review of literature was done using four search engines (PubMed, Google Scholar, Scopus, Science Direct) and keywords (individually and in combinations): prune belly syndrome, PBS, Eagle-Barrett syndrome, dental manifestation, clinical manifestation, and psychological aspects. The search was run with no language restrictions and covered the 1965-2021 time period. RESULTS The search yielded a large number of articles. The vast majority were dealing with a variety of treatments. PBS is a multisystem disease with a variable spectrum ranging from mild cases to infant mortality. Comorbidities of PBS (63% gastrointestinal, 65% orthopedic, and 49% cardiopulmonary) present challenges for treatment. PBS affects quality of life of patients and caregivers. We selected and summarized published information that is relevant to oral health and dental care. CONCLUSIONS AND PRACTICAL IMPLICATIONS Providing information to dental practitioners will improve their understanding of PBS. It will help them to better treat patients with PBS and it will encourage more dental providers to welcome patients with PBS into their dental clinics.

Abstract
BACKGROUND Prune belly syndrome (PBS) is a multisystem disease characterized by absent or deficient abdominal musculature with accompanying lax skin, urinary tract abnormalities, and cryptorchidism. Previous studies have estimated a birth prevalence of 1 in 35,000-50,000 live births. OBJECTIVE We set out to clarify the epidemiology and early hospital admissions of PBS in Finland through a population-based register study. Further, possible maternal risk factors for PBS were analyzed in a case-control setting. STUDY DESIGN The Finnish Register of Congenital Malformations was linked to the Care Register for Health Care, a population-based hospital admission data for PBS patients. Additionally, five matched controls were identified in the Birth Register and maternal risk factors of PBS were studied utilizing data from the Drugs and Pregnancy database. RESULTS We identified 31 cases of PBS during 1993-2015, 15 of which were live born and 16 elective terminations. The total prevalence was 1 in 44,000 births. Three patients (20%) died during infancy. On average, PBS-patients had 3.2 admissions and 10.6 hospital days per year in Finland during the study period years 1998-2015, 35- and 27-fold compared to children in Finland in general. Multiple miscarriages were significantly associated to PBS in maternal risk factor analyses. DISCUSSION The burden of disease is significant in PBS, demonstrated as a high infant mortality rate (20%), multiple hospital admissions, and inpatient care in days. The available variables are limited as a register-based study. CONCLUSION We present data on contemporary epidemiology in a population-based study and show that the total prevalence of PBS is 1 in 44,000 in Finland. PBS entails a significant disease burden with admissions and hospital days over 35- and 27-fold compared to the general pediatric population, further aggravated by an infant mortality rate of 20%.

Abstract
Background: Prune-belly syndrome is a rare congenital disorder characterized by a spectrum of three anomalies: bilateral undescended testes, dilated urinary tract, and anterior abdominal muscle deficiency. Objectives: In developing countries, inadequate access to health care may affect treatment and outcomes of prune-belly syndrome. This study’s goal was to review the anatomical features, etiology, genetics, management, and outcomes of cases in Africa. Methods: PubMed was searched to identify case reports and case studies describing prune-belly syndrome in Africa. Data collected from each study included the number of cases, age at diagnosis, sex, description of the abdominal muscles, testes, and urinary tract, as well as associated anomalies, management, and long-term outcomes. Results: A total of 16 publications that reported 58 cases in African countries were included. The prevalence of female patients (15.5%) was higher than in developed countries (3%). The abdominal muscles were deficient in all cases, and bilateral cryptorchidism was present in nearly all males (96%). Distension of the bladder was common, with normal anatomy reported in only one case. Bilateral hydroureters and hydronephrosis also were present in the majority of cases. Only six cases (10.3%) had no associated anomalies, such as musculoskeletal or cardiovascular. Karyotyping was performed in only three cases (5.2%) because of limited hospital facilities. Six parents (10.3%) declined treatment for their children, 12 cases (20.7%) were managed conservatively, and 25 (43.1%) received surgical intervention. Patients’ mortality rate was higher than in developed countries. Conclusion: Diagnosis and treatment of prune-belly syndrome remains a challenge in Africa, in which multiple factors, such as access to health care and cultural beliefs, affect mortality rates and outcomes. Patient education and support groups may improve compliance with treatment. Level of evidence: Not applicable for this multicenter audit.

Abstract
Prune belly syndrome (PBS) is characterized by the triad of abdominal flaccidity, a variable degree of urinary tract involvement and cryptorchidism. Most cases of PBS are sporadic and have a normal karyotype, with 95% patients being male. In the last decade, mutations in known genes that regulate embryonic genitourinary myogenesis have been identified and with increasing knowledge of these critical genes involved in bladder maldevelopment, advances can be made in genetic counseling. A multidisciplinary approach is necessary and individualization of care is recommended according to phenotypic severity. Some patients require abdominal and urinary tract reconstruction while others require as little as bilateral orchiopexies. Major treatment objectives are: preservation of renal function and upper urinary tract; polyuria management; adequate bladder emptying; improvement of corporal image and quality of life; preservation of fertility and adequate sexual function. Long-term surveillance of the urinary tract is essential up to adulthood, because functional dynamics can change over time.

Abstract
Prune belly syndrome (PBS) is a rare but morbid congenital disease, classically defined by a triad of cardinal features that includes cryptorchidism, urinary tract dilation and laxity of the abdominal wall musculature. Children often require numerous surgical interventions including bilateral orchidopexy as well as individually tailored urinary tract and abdominal wall reconstruction. Along with the classic features, patients with PBS often experience gastrointestinal, orthopedic, and cardiopulmonary comorbidities.

Abstract
RATIONALE Malformative uropathies represent a major cause of Chronic Kidney Disease (CKD) in children. Genitourinary system is the most frequent and sever affected in Prune-Belly syndrome cases. That is why the findings of early diagnosis and vigilant monitoring for these situations remain a major challenge for the medical team. PATIENT CONCERNS We present the clinical course of a 10 years old child with diagnosis of Prune-Belly syndrome. A urinary tract abnormality was suspected starting 25 weeks of gestation, when a routine ultrasound showed oligohydramnios, increased size urinary bladder, bilateral hydronephrosis and megaureters, thin abdominal wall. DIAGNOSIS Prenatal suspicion of Prune-Belly syndrome plays a deciding role in renal disease progression. A detailed clinical exam at birth established the diagnosis of Prune-Belly syndrome. Renal ultrasound confirmed bilateral grade III hydronephrosis and megaureters, with empty bladder, suggesting an obstruction at this level. A persistent urachus was confirmed by catheterization. Later it was used for imaging study that showed bilateral high grade reflux. INTERVENTIONS The main goal of any treatment is to preserve kidney function. Treatment options depend on the clinical picture. The pregnancy was closely monitorized, but fetal distress appeared so early labor was induced at 32 weeks. At beginning a temporary catheter was placed into the urachus which expressed urine. The urachus drain was left in place until the age of 6 weeks, when a bilateral ureterostomy was performed. Skeletal and genital malformations were present too; the child has undergone several surgeries to solve these abnormalities. OUTCOMES At the age of 10 years, he is a well-adapted child. He has had fewer than 3 urinary tract infections per year. Long term follow-up showed a relatively slow decline in the estimated Glomerular Filtration Rate in our child (62 ml/1.73m/min). LESSONS This case suggests that induced early labor could prove beneficial for early upper urinary tract decompression through earlier access to surgery. This is an option especially in situations or region where vesicoureteric or vesicoamniotic shunt placement is not available.

Abstract
Objective: Review outcomes of Prune Belly Syndrome (PBS) with the hypothesis that contemporary management improves mortality. Methods: A retrospective chart review of inpatient and outpatient PBS patients referred between 2000 and 2018 was conducted to assess outcomes at our institution. Data collected included age at diagnosis, concomitant medical conditions, imaging, operative management, length of follow-up, and renal function. Results: Forty-five PBS patients presented during these 18 years. Prenatal diagnoses were made in 17 (39%); 65% of these patients underwent prenatal intervention. The remaining patients were diagnosed in the infant period (20, 44%) or after 1 year of age (8, 18%). Twelve patients died from cardiopulmonary complications in the neonatal period; the neonatal mortality rate was 27%. The mean follow-up among patients surviving the neonatal period was 84 months. Forty-two patients had at least one renal ultrasound (RUS); of the 30 patients with NICU RUSs, 26 (89%) had hydronephrosis and/or ureterectasis. Of the 39 patients who underwent voiding cystourethrogram (VCUG), 28 (62%) demonstrated VUR. Fifty-nine percent had respiratory distress. Nine patients (20%) were oxygen-dependent by completion of follow up. Thirty-eight patients (84%) had other congenital malformations including genitourinary (GU) 67%, gastrointestinal (GI) 52%, and cardiac 48%. Sixteen patients (36%) had chronic kidney disease (CKD) of at least stage 3; three patients (7%) had received renal transplants. Eighty-four percent of patients had at least one surgery (mean 3.4, range 0-6). The most common was orchiopexy (71%). The next most common surgeries were vesicostomy (39%), ureteral reimplants (32%), abdominoplasty (29%), nephrectomy (25%), and appendicovesicostomy (21%). After stratifying patients according to Woodard classification, a trend for 12% improvement in mortality after VAS was noted in the Woodard Classification 1 cohort. Conclusions: PBS patients frequently have multiple congenital anomalies. Pulmonary complications are prevalent in the neonate while CKD (36%) is prevalent during late childhood. The risk of CKD increased significantly with the presence of other congenital anomalies in our cohort. Mortality in childhood is most common in infancy and may be as low as 27%. Contemporary management of PBS, including prenatal interventions, reduced the neonatal mortality rate in a subset of our cohort.

Abstract
Prune belly syndrome (PBS), also known as Eagle-Barrett syndrome, is a rare congenital disorder characterized by absence or hypoplasia of the abdominal wall musculature, urinary tract anomalies, and cryptorchidism in males. The etiology of PBS is largely unresolved, but genetic factors are implicated given its recurrence in families. We examined cases of PBS to identify novel pathogenic copy number variants (CNVs). A total of 34 cases (30 males and 4 females) with PBS identified from all live births in New York State (1998-2005) were genotyped using Illumina HumanOmni2.5 microarrays. CNVs were prioritized if they were absent from in-house controls, encompassed ≥10 consecutive probes, were ≥20 Kb in size, had ≤20% overlap with common variants in population reference controls, and had ≤20% overlap with any variant previously detected in other birth defect phenotypes screened in our laboratory. We identified 17 candidate autosomal CNVs; 10 cases each had one CNV and four cases each had two CNVs. The CNVs included a 158 Kb duplication at 4q22 that overlaps the BMPR1B gene; duplications of different sizes carried by two cases in the intron of STIM1 gene; a 67 Kb duplication 202 Kb downstream of the NOG gene, and a 1.34 Mb deletion including the MYOCD gene. The identified rare CNVs spanned genes involved in mesodermal, muscle, and urinary tract development and differentiation, which might help in elucidating the genetic contribution to PBS. We did not have parental DNA and cannot identify whether these CNVs were de novo or inherited. Further research on these CNVs, particularly BMP signaling is warranted to elucidate the pathogenesis of PBS.
