OBJECTIVES: Laparoscopic ureteral reconstructive surgery is routinely performed , because it demonstrated efficacy and safety profiles similar to open surgery in expert hands. The most frequent surgical complications after transplant are urological, appearing in up to 12,5% of the cases; they can compromise graft function and mortality. The most frequent ones include ureterovesical anastomosis stenosis (2,5-7,5%) and vesicoureteral reflux (0,4-2,2), which present in up to 80% of the cases...

Spinal cord injury (SCI) is often accompanied by reduced bladder compliance, which contributes to adverse conditions including urinary tract infections and vesicoureteral reflux. Reduced compliance is, in part, attributed to extensive remodeling of the bladder wall including the extracellular matrix (ECM). Here we tested the hypothesis that blockade of matrix metalloproteinases (MMPs), known for their ability to remodel the ECM, improves bladder compliance in dogs with SCI. We first evaluated dogs with naturally occurring SCIs resulting from intervertebral disc herniation (IVDH)...

Type IV renal tubular acidosis is known to occur in obstructive uropathy with urinary tract infection. Fanconi syndrome, however, has not been described in these settings. We report two preterm infants who developed Fanconi syndrome associated with hydronephrosis and urinary tract infection. Patient 1 is a boy with 21 trisomy, bilateral renal hypoplasia and bilateral vesicoureteral reflux delivered at 35 weeks' gestation. At postnatal day 42, he developed Fanconi syndrome after urinary tract infection, which persisted until the surgical correction of vesicoureteral reflux...

BACKGROUND: Vesicoureteric reflux (VUR) is an important association of paediatric urinary tract infection (UTI) found in 30-50% of all children presenting with first UTI. Contrast-enhanced voiding ultrasonography (ceVUS) has become an important radiation-free method for VUR detection in children. Its sensitivity in detecting VUR has greatly improved due to the development of the contrast-specific ultrasound techniques and the introduction of the second-generation ultrasound contrast agent, superseding the diagnostic accuracy of standard radiological procedures...

BACKGROUND: Albuminuria is a potential biomarker of chronic kidney disease (CKD) in various glomerular diseases. Vesicoureteral reflux (VUR) often progresses to CKD, and study is required of use of albuminuria as a biomarker for this condition. The aim of this study was to evaluate the association between albuminuria and glomerular filtration rate (GFR) or filtration fraction (FF) in children with VUR. STUDY DESIGN: In this retrospective study, renal parameters of 141 children with VUR were investigated, using inulin clearance, FF, and albuminuria...

Urinary tract infection (UTI) is common in young children and may cause pyelonephritis and renal scarring. Long-term complications from renal scarring are low. The role of imaging is to evaluate for underlying urologic abnormalities and guide treatment. In neonates there is increased risk for underlying urologic abnormalities. Evaluation for vesicoureteral reflux (VUR) may be appropriate especially in boys because of higher prevalence of VUR and to exclude posterior urethral valve. In children older than 2 months with first episode of uncomplicated UTI, there is no clear benefit of prophylactic antibiotic...

BACKGROUND: Imaging of the kidneys and urinary tract has a significant and critical role for diagnosis of genitourinary system diseases. Although technological progress goes toward less invasive approaches, some of the current methods are still invasive and annoying. Voiding cystourethrography (VCUG) is the best and most accurate method for diagnosis and grading of vesicoureteral reflux. VCUG is a distressful procedure that gives serious anxiety and pain in a large proportion of children and fear for parents; therefore, using effective sedative drugs with the least side effects is necessary and should be considered...

BACKGROUND: Hypertension (HTN) is a late outcome of congenital or acquired renal scar. We used ambulatory blood pressure to assess the early blood pressure abnormalities in children with history of urinary tract infection with various degrees of renal scars. METHODS: Between 2009 and 2011, 60 (45 females, 15 males) children aged 5-15 years and height equal or more than 120 cm with previous history of febrile urinary tract infection were entered into the study. All children went on 24-hour ambulatory blood pressure monitoring (24-H ABPM)...

PURPOSE: Despite minimal invasiveness and high success rate, guidelines still prescribe voiding Cystourethrogram (VCUG) after endoscopic treatment for vesicoureteral reflux (VUR) in children. The aim of this paper was to analyze whether intraoperative ultrasound (IO-US) could improve surgical accuracy and perioperative counseling, thus potentially decreasing the need for postoperative VCUG. METHODS: We selected children treated for moderate to high grade VUR, renal scarring or repeated infections under antibiotic prophylaxis from January to December 2015...

Most congenital anomalies of the kidney and urinary tract (CAKUT) are sporadic, but familial occurrence has been described, suggesting a genetic contribution. Copy‑number variations (CNVs) were detected in patients with CAKUT to identify possible novel genomic regions associated with CAKUT. CNVs were investigated in 7 children with CAKUT from three unrelated families using array comparative genomic hybridization: female monozygotic twins with bilateral duplex collecting system/vesicoureteral reflux (VUR)/unilateral renal hypodyspasia (URHD); two male siblings with VUR/URHD; 3 male second cousins, one with bilateral VUR/URHD, one with bilateral VUR and one with ureterovesical junction obstruction (UVJO)...

INTRODUCTION: Lower urinary tract dysfunction (LUTD) involves faults in the filling and emptying phases of bladder function in toilet-trained children with no previous infection or any other obvious pathology. Lower urinary tract dysfunction is associated with conditions such as vesicoureteral reflux, recurrent urinary infection, behavioral alterations and decreased quality of life. The literature suggests an association between LUTD and obesity; however, the association between each individual symptom and obesity has yet to be evaluated...
