Delta neutrophil index (DNI) is the fraction of circulating immature granulocytes, which reflects severe bacterial infections and septic condition but has not been studied in urinary tract infection (UTI). Here, we evaluated the value of DNI in predicting acute pyelonephritis (APN) or vesicoureteral reflux (VUR) using the data of 288 patients. Conventional inflammatory markers (white blood cell [WBC] count, erythrocyte sedimentation rate [ESR], C-reactive protein [CRP]), and DNI were measured. WBC, CRP, ESR and DNI were higher in APN than in lower UTI (p < 0...

Ureteral atresia is a rare disease usually associated with a non-functioning dysplastic kidney. The condition may be unilateral or bilateral; focal, short or long and may involve any part of the ureter. Association with other urinary anomalies is rare. We report the case of a 10-month-old boy with prenatal diagnosis of multicystic right kidney. This suspicion was confirmed after birth by ultrasound and static scintigraphy; a right vesicoureteral reflux (VUR) was recorded at cystography. The boy presented a regular renal function but was hospitalized twice for suspected pyelonephritis between the 8th and the 10th month of life and were recorded occasional mild changes in blood pressure...

Endoscopic management is the gold standard for symptomatic low-grade vesicoureteral reflux (VUR) in children. Deflux(®) (hyaluronic acid/dextranomer) injection is highly effective and has very few complications. We report on two cases of secondary megaureter after Deflux(®) injections. In the first case, a boy presented with Grade 4 VUR. He received a bilateral Deflux(®) injection with a total of three syringes. The postoperative ultrasound was normal. However, a check-up ultrasound 3 years later showed a significant ureteropyelocalyceal dilatation, with stasis and decreased renal function on scintigraphy, the reason why antireflux surgery (Cohen procedure) was performed...

Urinary tract infections (UTI) are the most common bacterial infections in children. The symptoms are not very specific and range from abdominal pain, poor feeding to nocturnal urinary incontinence. The technique of collecting urine plays an important role for securing the diagnosis. The best way to obtain urine in non-toilet-trained children is catheterization or suprapubic bladder aspiration. In toilet-trained children midstream urine is an acceptable alternative after cleaning the foreskin or labia. In the case of an infection a prompt empirical antibiotic therapy is necessary to reduce the risk of parenchymal scarring of the kidneys...

We report a rare case of extravasation of urine, which may be associated with bilateral complete ureteral duplication, vesicoureteral reflux (VUR), and benign prostatic hyperplasia (BPH). A 71-year-old male presented with a complaint of right abdominal pain. An extravasation of urine was noted, and was improved by indwelling urethral catheterization. Transurethral resection of the prostate and the endoscopic subureteral injection of dextanomer/hyaluronic acid were performed for the treatment of BPH and VUR, respectively...

BACKGROUND: The invasiveness and exposure to radiation in voiding cystourethrography led to the introduction of alternative methods of diagnosis of vesicoureteral reflux, including contrast enhanced voiding urosonography. While there is a limited number of studies comparing these methods using new generation ultrasound contrast agents, none of them compared both methods simultaneously. This study is aimed at assessing agreement between contrast enhanced voiding urosonography with second-generation ultrasound contrast agents and voiding cystourethrography...

PURPOSE: Robot-assisted laparoscopic extravesical ureteral reimplantation (RALUR-EV) has been proposed as a minimally invasive alternative to open ureteral reimplantation for correcting primary vesicoureteral reflux (VUR) in children. However, in the current literature there are conflicting data regarding the safety and efficacy of this approach. Amidst ongoing debate, we analyzed outcomes and complications from this procedure in a large, multi-institutional cohort. MATERIALS AND METHODS: We reviewed the records of children who underwent RALUR-EV at 9 academic centers from 2005 to 2014...

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 bladder exstrophy in male patients...

We reported a 4-year-old girl with history of bilateral vesicoureteral reflux who underwent direct radionuclide cystography in our department. Radiotracer was mistakenly injected in the catheter balloon. The filling phase showed no change in the bladder volume, and the catheter balloon was apparent as an intense activity in the base of the bladder. The procedure was repeated with correct injection of the tracer into the catheter. Wrong injection of the radiotracer into the catheter balloon should always be borne in mind in similar cases...

Spinal cord injury (SCI) may lead to urinary system disturbances. Patients with SCI usually have neurogenic bladder, and treatment optionss for this condition include clean intermittent catheterization and a permanent indwelling urethral or suprapubic catheter. Complications of catheterization include urinary tract infection, calculi, urinary tract injury, bladder contraction, bladder spasm, renal dysfunction, bladder cancer, and so forth. To the best of our knowledge, ureteral rupture is an unusual complication of catheterization, and ureteral rupture has been rarely reported in SCI patients...

Hydronephrosis may be related to an obstructive cause, ureteropelvic/uretero-vesical junction obstruction or nonobstructive [vesicoureteral reflux (VUR)]. When an obstructive pathology is considered, dynamic renal scintigraphy may help to predict whether it is a true obstruction or not. In this study, we aimed to determine the contribution of dynamic renal scintigraphy with [99] mTc-MAG-3 to the clinical decision-making for surgery in hydronephrotic children. Files of the patients evaluated by MAG-3 scintigraphy for antenatal (AH)/postnatal (PH) hydronephrosis between 1992 and 2014 were reviewed...

REVIEW
Minki Baek, Chester J Koh
The da Vinci robotic system has improved surgeon dexterity, ergonomics, and visualization to allow for a minimally invasive option for complex reconstructive procedures in children. Over the past decade, robot-assisted laparoscopic ureteral reimplantation (RALUR) has become a viable minimally invasive surgical option for pediatric vesicoureteral reflux (VUR). However, higher-than-expected complication rates and suboptimal reflux resolution rates at some centers have also been reported. The heterogeneity of surgical outcomes may arise from the inherent and underestimated complexity of the RALUR procedure that may justify its reclassification as a complex reconstructive procedure and especially for robotic surgeons early in their learning curve...

INTRODUCTION AND OBJECTIVE: Management of vesicoureteral reflux (VUR) remains controversial, and reflux grade constitutes an important prognostic factor. Recent work has suggested that distal ureteral diameter ratio (UDR) is a predictive factor relative to clinical outcome independent of grade. Previous studies have noted significant inter-rater variability with grading of VUR. The present study compared inter-rater reliability of reflux grade and UDR in children with primary VUR. STUDY DESIGN: Four pediatric urologists independently reviewed, in a blinded fashion, voiding cystourethrograms...

Urinary tract infections (UTI) are one of the most common infections in children and symptoms may be nonspecific. The risk of renal scarring is highest in children under 1 year of age with febrile UTI and high-grade vesicoureteral reflux (VUR). Although treatment of UTI is usually straightforward, given increased rates of antimicrobial resistance worldwide, the choice of treatment for pediatric UTI should be guided by community resistance patterns whenever feasible. The benefit of antimicrobial prophylaxis after first UTI and/or in the presence of VUR remains controversial, but a recent meta-analysis supports continuous antimicrobial prophylaxis in children with VUR, indicating a need for more research in this area...
