Knowledge of vesicoureteral reflux obtained by screening voiding cystourethrogram in children with multicystic dysplastic kidney does not change patient management or prevent febrile urinary tract infection.

J Pediatr Urol 2019 Mar 22. Epub 2019 Mar 22.

Nationwide Children's Hospital, 700 Children's Drive, Columbus, OH 43205, USA.

Introduction: While children with multicystic dysplastic kidneys (MCDK) are predisposed to contralateral kidney (CK) vesicoureteral reflux (VUR), it is unknown if this results in an increased risk of urinary tract infection (UTI). The authors hypothesized that knowledge of VUR via voiding cystourethrogram (VCUG) would enable altered practices to prevent UTI and thus reduce the number of febrile urinary tract infections (fUTIs).

Methods: The authors performed a retrospective chart review of all patients at their institution of multiple providers caring for patients with a diagnosis of MCDK from 1/1/07 to 7/14/17. Read More

Prenatal extravasation of urine seems to preserve renal function in boys with posterior urethral valves.

J Pediatr Urol 2019 Feb 27. Epub 2019 Feb 27.

Oslo University Hospital, Department of Pediatric Surgery, Norway.

Introduction: A posterior urethral valve (PUV) may lead to extravasation of urine, resulting in prenatal ascites and/or perirenal urinoma. Extravasation has been presumed to act as a pop-off mechanism, preserving renal function, but previous reports addressing this presumption have been inconclusive.

Aim Of Study: The present study compares renal function in patients with PUV with and without extravasation. Read More

H.K.H. Crown Princess Victoria´s Hospital for Children and Youth and Division of Pediatrics, Department of Clinical and Experimental Medicine, Linköping University, SE 58185 Linköping, Sweden. Electronic address:

Introduction: Night-time polyuria as the dominating pathophysiological mechanism for primary monosymptomatic nocturnal enuresis (PMNE) has been put in question with nocturnal detrusor overactivity and high arousal thresholds as alternatives. An earlier finding of night-time polyuria in 12% of healthy non-enuretic schoolchildren underscores that excessive night-time diuresis per se is unlikely the major cause of PMNE.

Objective: The objective of this study was to compare the night-time diuresis pattern in children with and without PMNE and to evaluate the role of night-time polyuria in provoking enuretic episodes in children with PMNE. Read More

Pathological changes in ureterovesical and ureteropelvic junction obstruction explained by fetal ureter histology.

J Pediatr Urol 2019 Feb 11. Epub 2019 Feb 11.

Department of Pathology, Sri Ramachandra Institute of Higher Education and Reseach, Porur, Chennai 600116, India.

The etiology of ureterovesical junction obstruction (UVJO) and ureteropelvic junction obstruction (UPJO) is obscure with an adynamic narrow segment causing the obstruction. In this study, the authors compared interstitial cells of Cajal (ICC) and collagen-to-muscle ratio (CM ratio) between UVJO, UPJO, and fetal ureters to investigate whether a maturational arrest of the fetal ureter could explain both clinical pathologies.

Methods: Group 1 (control) involved specimens of the normal ureter (nephrectomy for trauma/tumor; n = 20), while group 2, specimens of UVJO (n = 14); group 2 was further divided into group 2a, the dilated megaureter above UVJO, and group 2b, UVJO narrow segment; group 3, UPJO narrow segment excised during pyeloplasty (n = 31); and group 4, normal fetal ureters (n = 12).

Factors related to lymph node sampling at the time of surgery in children, adolescents, and young adults with unilateral non-metastatic renal cell carcinoma.

J Pediatr Urol 2019 Feb 1. Epub 2019 Feb 1.

University of Colorado, Department of Surgery, Division of Urology, Children's Hospital of Colorado, Aurora, CO, USA. Electronic address:

Introduction: Renal cell carcinoma (RCC) is rare in the pediatric, adolescent, and young adult (PAYA) population. PAYA patients with RCC have a high rate of lymph node (LN) involvement, regardless of primary tumor size, yet data to guide surgical LN management in this group are limited.

Objective: The objective of this study was to determine what factors are associated with LN sampling (protocol adherence) in PAYAs with RCC. Read More

Renal cyst evolution in childhood: a contemporary observational study.

J Pediatr Urol 2019 Feb 1. Epub 2019 Feb 1.

Faculty of Medicine, University of Ottawa, Ottawa, ON, Canada; Division of Urology, Department of Surgery, Children's Hospital of Eastern Ontario, Ottawa, ON, Canada.

Introduction: Children with renal cysts often undergo ultrasound (US) monitoring to identify malignant transformation or polycystic kidney disease (PKD). However, the utility of ongoing surveillance is uncertain.

Objective: The objective of this study was to assess the natural history of simple or minimally complex cysts and the proportion of progression to autosomal dominant polycystic kidney disease (ADPKD), autosomal recessive polycystic kidney disease (ARPKD), or malignancy. Read More

Diuresis renography in the evaluation and management of pediatric hydronephrosis: What have we learned?

J Pediatr Urol 2019 Jan 28. Epub 2019 Jan 28.

Division of Pediatric Urology, Children's National Health System, Washington, DC, USA. Electronic address:

Diuresis renography (DR) is widely used in the evaluation of hydronephrosis and hydroureter in infants and children. The goal of this provocative nuclear imaging examination should be to detect the hydronephrotic kidneys at risk for loss of function and development of pain, hematuria, and urinary tract infection. The reliability of DR is dependent on the acquisition and processing of the data as well as interpretation and utilization of the results. Read More

Association between urodynamic parameters and urine neutrophil gelatinase-associated lipocalin concentrations in children with neuropathic bladders.

J Pediatr Urol 2019 Jan 23. Epub 2019 Jan 23.

Department of Surgery, Cincinnati Children's Hospital Medical Center, 3333 Burnet Ave, Cincinnati, OH, 45229, USA. Electronic address:

Background: Neutrophil gelatinase-associated lipocalin (NGAL) is a marker of acute kidney injury, and has been shown to be a sensitive marker of renal damage in urinary tract obstruction. Children with neurogenic bladders are at risk of renal damage as a result of increased pressure within the urinary system. A marker of upper tract deterioration in this population would be useful to guide management. Read More

University of Nebraska Medical Center/Children's Hospital and Medical Center, 8200 Dodge Street, Omaha, NE 68114, USA. Electronic address:

Introduction: Some infants with obstructed megaureters or ectopic ureters requiring surgery undergo a cutaneous ureterostomy followed by definitive repair after 12 months of age. Since 2013, a 'mini' extravesical reimplant with or without 'mini' tapering (MER) was performed instead of cutaneous ureterostomy in such infants.

Objective: To describe the technique and outcomes for MER. Read More
