PURPOSE: To investigate the role of acoustic radiation force impulse (ARFI) elastography in the detection of renal parenchymal damage in kidneys with and without ureteropelvic junction obstruction (UPJO). METHODS: Twenty-five pediatric patients with a diagnosis of UPJO who underwent surgery and 15 pediatric patients with conservatively managed UPJO were prospectively evaluated with ARFI elastography. Sixteen healthy volunteers constituted the control group. Shear wave velocity (SWV) measurements in the upper, mid, and lower poles of the affected kidney were performed...

BACKGROUND: Kidney transplantation in highly-sensitized (HS) patients can improve with organ-exchange strategies based on virtual crossmatch (V-XM). Experience in very-HS patients is limited. METHODS: In June 2012, Andalusia started a V-XM protocol for very-HS patients (calculated panel reactive antibodies ≥95%). After organ allocation a cytotoxic-XM performed immediately before transplantation had to be negative for surgery to proceed. We analyzed results up until December 2015...

REVIEW
John J Bissler, John C Kingswood
Renal angiomyolipomata associated with tuberous sclerosis complex are often bilateral, multiple and progressive. They cause significant morbidity and mortality in older children and adults. Surveillance and pre-emptive treatment reduce this risk. Recent research suggests treatment with mammalian target of rapamycin inhibitors is better at preventing bleeding, recurrence, and preserving renal function than percutaneous embolization.

A shear wave velocity (SWV) value obtained by the acoustic radiation force impulse technique depends on tissue elasticity. We investigated the relationship between SWV values and the estimated glomerular filtration rate (eGFR) in children with chronic kidney disease. A total of 29 patients were enrolled in the study. There were 18 primary and 11 secondary cases of vesicoureteral reflux. eGFR was calculated using Schwartz's formulas (2012). Partial eGFR for each kidney was assessed by multiplying the eGFR by the percentage of renal function measured by means of renal (99m)Tc-dimercaptosuccinic acid scintigraphy...

BACKGROUND: The survival rates of renal transplant children are indeed on the rise, but it is still important to ensure that there is optimal renal function in these children in all their future growing years. The number of functioning nephrons and the graft ability to adapt to an increasing demand during body growth seem to be the most important factors for long-term allograft function. This study examined the long-term change in the glomerular filtration rate in a pediatric kidney transplant cohort and the importance of the recipient and donor ages in predicting transplant outcome...

BACKGROUND: Spina bifida increases the risk for urinary tract infections (UTI). Antimicrobial prophylaxis (AP) reduces symptomatic UTI's but selects resistant organisms. Measures to ensure regular and complete emptying of the bladder combined with treatment of constipation reduce the risk for UTI. OBJECTIVES: Demonstrate that close adherence to a catheterization regimen in children with spina bifida (Selective Treatment - ST) reduces the need for antimicrobial prophylaxis...

BACKGROUND: Oral vancomycin is used to treat refractory colitis due to Clostridium dificile infection. Traditionally, oral vancomycin was thought to not be absorbed systemically, but recent adult studies have demonstrated detectable serum levels in over half of patients with severe colitis. This has not been studied in children. OBJECTIVE: To determine the absorption of oral vancomycin and the renal safety profile of oral vancomycin in children hospitalized with colitis. METHODS: We performed a prospective, observational, pilot proof of principle study at the North Carolina Children's Hospital in patients 2 years to 18 years of age receiving oral vancomycin for the treatment of C dificile colitis...

REVIEW
Lesley Rees
Chronic irreversible kidney disease requiring dialysis is rare in the neonate. Many such neonates are diagnosed following antenatal ultrasound with congenital abnormalities of the kidneys and urinary tract. There is an increased incidence of prematurity and infants that are small for gestational age. Given the natural improvement in renal function that occurs in the neonatal period, some with extremely poor renal function may, with careful management of fluid and electrolytes, be kept off dialysis until the creatinine reaches a nadir when a definitive plan can be made...

Urticaria is common in children. Urticarial vasculitis (UV) is a potentially more serious, rare variant. The youngest reported case was 12 months of age. A systemically well, 19-month-old girl presented with her mother who was concerned about the development of a rash. On presentation, the child had normal vital signs, was alert, and was well and playing with toys. There was a widespread urticarial rash (raised, pruritic, and erythematous) that was most apparent on the trunk with minimal rash on the legs. Overlying this urticarial rash in a similar distribution was a blotchy, palpable purpuric rash and associated hyperpigmentation...

REVIEW
Rosanna Coppo
The identification of risk factors conditioning the progression of immunoglobulin (Ig)A nephropathy (IgAN) is needed due to the variability of the outcome of this renal disease, which ranges from remission or indolent course to progressive slow loss of renal function or rapidly evolving chronic renal failure. Based on the supposed individual risk of progression, the therapy is modulated from renin-angiotensin inhibitors to corticosteroids, alone or associated with other powerful but potentially harmful immunosuppressors...

INTRODUCTION: The surgical correction of bladder exstrophy remains challenging. In our institution, the repair has evolved from a staged repair to one-stage reconstruction. The one-stage reconstruction includes; bladder closure, Cantwell-Ransley neourethroplasty and abdominoplasty using groin flaps, without the need of pelvic ostheotomies. Repair of urinary continence (UC) and vesicoureteral reflux (VUR) is done after development of the infant. OBJECTIVE: To present our experience of our modified one-stage reconstruction of bla¬dder exstrophy in male patients...

BACKGROUND AND OBJECTIVES: The complement inhibitor eculizumab has dramatically improved the outcome of atypical hemolytic uremic syndrome. However, the optimal duration of eculizumab treatment in atypical hemolytic uremic syndrome remains debated. We report on the French atypical hemolytic uremic syndrome working group's first 2-year experience with eculizumab discontinuation in patients with atypical hemolytic uremic syndrome. DESIGN, SETTING, PARTICIPANTS & MEASUREMENTS: Using the French atypical hemolytic uremic syndrome registry database, we retrospectively identified all dialysis-free patients with atypical hemolytic uremic syndrome who discontinued eculizumab between 2010 and 2014 and reviewed their relevant clinical and biologic data...

Vesicoureteral reflux (VUR) is diagnosed in ∼1% of children. The main goal of treatment is preservation of renal function by preventing recurrent urinary tract infection (UTI) refractory to antibiotic therapy. Surgical treatment options include endoscopic injection or ureteral reimplantation. Subureteral Teflon (polytetrafluoroethylene) injection (STING) is an endoscopic treatment option no longer in common practice. Use of Teflon is no longer advised because of a number of documented complications secondary to local and distant migration of injected material...
