Prune belly syndrome

We present a case of megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) in a four days old female infant who presented with abdominal distension, bilious vomiting, massive hematuria and feeding intolerance which was first interpreted as Prune Belly Syndrome (PBS), referred to our department after iatrogenic gastric and colonic perforation. Berdon syndrome or MMIHS is a rare congenital anomaly characterized by a massive enlarged bladder, distended abdomen, microcolon, functional obstruction of the gastrointestinal tract, and malrotation...

Unilateral pseudo prune belly syndrome (PPBS) is a rare variant with only two other cases found in the main literature until. We present a 9-month old boy with left-sided lax abdominal wall, undescended testes and major vesicoureteric reflux involving only the left side. He underwent left orchidopexy and left end ureterostomy followed by left nephrectomy. Unilateral variant supports the theory of mesodermal arrest as a cause for prune belly syndrome. Treatment is individualised and prognosis is relatively better when compared with other variants of PPBS...

Fetal lower urinary tract obstruction (LUTO) is classically based on prenatal ultrasound identification of a dilated/ thick-walled bladder, bilateral hydronephrosis, dilated ureters and a dilated posterior urethra (also known as the "keyhole sign") in a male fetus. Although the most common underlying diagnosis is posterior urethral valves, the prenatal appearance may be similar with urethral atresia or stenosis, the Prune-Belly Syndrome, or even a cloacal anomaly in a female. These conditions form part of the Congenital Anomalies of Kidney and Urinary Tract (CAKUT) spectrum, which is the commonest cause of end-stage renal disease in children...

The Prune-Belly syndrome (PBS) is a rare pathology predominating in male infants, classically manifesting with the triad including aplasia of the abdominal wall muscles, dilatation of the urinary tract, and testicular abnormalities. We report and discuss the case of a full-term male newborn, in whom clinical examination at birth revealed abdominal wall muscle hypoplasia, cryptorchidism, urinary tract dilatation and renal failure. The diagnosis was made based on physical assessment, abdominal ultra-sonographic imaging, and blood sampling of urea and creatinine...

OBJECTIVES: This review aims to study the role of the abdominal wall in testicular migration process during the human fetal period. MATERIALS AND METHODS: We performed a descriptive review of the literature about the role of the abdominal wall in testicular migration during the human fetal period. RESULTS: The rise in intra-abdominal pressure is a supporting factor for testicular migration. This process has two phases: the abdominal and the inguinal-scrotal stages...

BACKGROUND: Pressure pop-offs, such as high-grade vesicoureteral reflux with renal dysplasia, have historically been considered beneficial for renal and bladder outcomes in boys with posterior urethral valves (PUV). Recent longer-term studies have called into question the beneficial effects of pop-offs on renal function. OBJECTIVE: To evaluate how pop-offs affect bladder outcomes in boys with PUV. STUDY DESIGN: At a single-center, the electronic medical records of boys with PUV who underwent valve ablation from 2000 to 2014 were retrospectively reviewed for bladder and continence outcomes...

INTRODUCTION: In 2017, UCSF established a formal Transitional Urology (TU) clinic co-run by pediatric and adult urology aimed at providing comprehensive urologic care for people progressing into adulthood with complex urologic histories. OBJECTIVE: We aim to describe baseline demographic and disease characteristics of this population, understand gaps in care, and gauge follow-through. STUDY DESIGN: We performed a retrospective chart review of all new patients in the TU clinic at UCSF from February 2017 through January 2019...

OBJECTIVE: To gain insight into the causes of infertility in Prune Belly Syndrome (PBS) by evaluating reproductive system anatomy and gonadal function in a cohort of postpubertal PBS patients. METHODS: We contacted all PBS patients 14 years old or older treated and followed at our institution. Age at orchiopexy, type of orchiopexy (with or without ligation of gonadal vessels), testicular volumes and positions were evaluated. Pelvic magnetic resonance imaging (to assess prostate size, seminal vesicles, and vas) and hormonal profile were ordered...

The role of the pediatric urologic surgeon does not end with initial reconstructive surgery. Many of the congenital anomalies encountered require multiple staged operations while others may not involve further surgery but require a life-long follow-up and often revisions. Management of most of these disorders must extend into and through adolescence before transitioning these patients to adult colleagues. The primary goal of management of all congenital uropathies is protection and/or reversal of renal insult...

BACKGROUND: Prune belly syndrome (PBS) is a rare, multi-system congenital myopathy primarily affecting males that is poorly described genetically. Phenotypically, its morbidity spans from mild to lethal, however, all isolated PBS cases manifest three cardinal pathological features: 1) wrinkled flaccid ventral abdominal wall with skeletal muscle deficiency, 2) urinary tract dilation with poorly contractile smooth muscle, and 3) intra-abdominal undescended testes. Despite evidence for a genetic basis, previously reported PBS autosomal candidate genes only account for one consanguineous family and single cases...

Prune belly syndrome (PBS) is a rare multisystemic disease characterized by a deficiency of abdominal wall musculature, urinary tract anomalies and bilateral intra-abdominal testes. PBS in females is called pseudo prune belly syndrome (PPBS) and is characterized by abdominal wall laxity and urinary tract defects. We report three male and one female stillborn piglets with abdominal distension, hypoplastic abdominal wall musculature and urinary tract anomalies. Bilateral cryptorchidism was observed in the males...

BACKGROUND: To compare the growth of the prostate in anencephalic, prune belly syndrome (PBS) and control fetuses. METHODS: We studied 35 prostates from normal human fetuses aged 11-22 weeks postconception (WPC); 15 from anencephalic fetuses aged 13-19 WPC; and 6 from PBS fetuses aged 13-31WPC. After prostate dissection, we evaluated the prostate length, width and thickness with the aid of a computer program (Image Pro and Image J). The fetal prostate volume (PV) was calculated using the ellipsoid formula: PV = [length × thickness × width] × 0...

Background: Most congenital anomalies of the urinary tract present with hydronephrosis. Some are physiological while others pathological. Ultrasound, micturating cyst urethrography, dynamic renal scintigraphy, intravenous urography, dynamic and static magnetic resonance urography are used for examination. Currently, renal arterial Doppler resistance index is used as complimentary mechanism. This study assesses our experience in resistive index measurement in differentiating obstructive from non-obstructive hydronephrosis in children...

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...

CHRM3 codes for the M3 muscarinic acetylcholine receptor that is located on the surface of smooth muscle cells of the detrusor, the muscle that effects urinary voiding. Previously, we reported brothers in a family affected by a congenital prune belly-like syndrome with mydriasis due to homozygous CHRM3 frameshift variants. In this study, we describe two sisters with bladders that failed to empty completely and pupils that failed to constrict fully in response to light, who are homozygous for the missense CHRM3 variant c...

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...

BACKGROUND: There are no reports comparing testicular volume between normal fetuses, fetuses with prune-belly syndrome (PBS), and fetuses with anencephaly. The study hypothesis was that PBS and especially anencephaly alter the testicular volume during the human fetal period. AIM: The objective of the study was to compare the testicular growth in fetuses with anencephaly, with PBS, and without anomalies. STUDY DESIGN: This is a morphometric study of human fetuses...

BACKGROUND: Prune belly syndrome is a rare congenital condition of uncertain etiology. It is characterized with a triad of abdominal distension due to deficient abdominal wall, genitourinary tract anomalies, and musculoskeletal anomalies. This condition varies in its severity which makes diagnosis challenging during early antenatal scanning. CASE PRESENTATION: We reported a severe phenotype of prune belly syndrome which was not fully suspected in a 29-year-old Saudi woman was G4T2P0A1L2 at 21 weeks of gestation at the time of early antenatal presentation; however, it became apparent during diagnosis at a subsequent follow-up scan during advanced gestational age...
