BACKGROUND AND OBJECTIVE: Urinary tract infection (UTI) is a frequent disorder of childhood, yet the proper approach for a child with UTI is still a matter of controversy. The objective of this study was to critically compare current guidelines for the diagnosis and management of UTI in children, in light of new scientific data. METHODS: An analysis was performed of the guidelines from: American Academy of Pediatrics (AAP), National Institute for Health and Care Excellence (NICE), Italian Society of Pediatric Nephrology, Canadian Paediatric Society (CPS), Polish Society of Pediatric Nephrology, and European Association of Urology (EAU)/European Society for Pediatric Urology (ESPU)...

Fetal megacystis is variably defined and understood. The literature on fetal megacystis was systematically reviewed, focusing on prenatal diagnosis, associations and outcomes. This yielded a total of 18 primary references and eight secondary references. Fetal megacystis has an estimated first-trimester prevalence of between 1:330 and 1:1670, with a male to female ratio of 8:1. In the first trimester, megacystis is most commonly defined as a longitudinal bladder dimension of ≥7 mm. Later in pregnancy, a sagittal dimension (in mm) greater than gestational age (in weeks) + 12 is often accepted...

OBJECTIVE: To assess the long-term impacts of bladder neck incision (BNI) on continence and ejaculatory function of adults who underwent concurrent posterior urethral valve (PUV) ablation and BNI during childhood. MATERIALS AND METHODS: A retrospective chart review was performed to find all adult patients with relevant history. All patients had undergone BNI at 6 o'clock proximal to the verumontanum with caution to leave the adventitia and verumontanum untouched...

CONTEXT: Undescended testis is the most common endocrinological disease in the male newborn period. Incidence varies between 1.0% and 4.6% in full-term neonates, with rates as high as 45% in preterm neonates. Failure or delay of treatment can result in reduced fertility and/or increased testicular cancer risk in adulthood. OBJECTIVE: To provide recommendations for the diagnosis and treatment of boys with undescended testes which reduce the risk of impaired fertility and testicular cancer in adulthood...

BACKGROUND: The association of rectovestibular fistula (RVF) and vaginal agenesis (VA) presents a diagnostic and management challenge. The vaginal replacement is usually performed with rectum or sigmoid, which are the natural fecal reservoirs; thus, the fecal control could be affected. We present our experience utilizing ileum to preserve the rectum and sigmoid. METHODS: We performed a retrospective study of eight patients with RVF and VA treated from May 2011 to June 2015 at two colorectal centers, at Pittsburgh and Mexico...

BACKGROUND: Through the completion of the first year of life, cryptorchidism is the most common genital malformation in pediatric urology; unilateral cryptorchidism is detected in about 1% of full-term male infants and a fifth (20%) of children are bilaterally affected. DISCUSSION: It must be understood that azoospemia affects about 10% of men with unilateral and about 32% of men with bilateral cryptorchidism and that approximately 10-20% of men, in whom infertility has been diagnosed, have a history of orchiopexy...

Undescended testes (UDT), where one or both testes fail to migrate to the base of the scrotum, can be congenital (2-5% of newborn males) or acquired (1-2% of males). The testis may be found in any position along its usual line of descent. Cryptorchidism affects the developing testicular germ cells and increases the risk of infertility and malignancy. Clinical management aims to preserve spermatogenesis and prevent the increased risk of seminoma. Examination to document the testicular position will guide the need for imaging, medical management and the surgical approach to orchidopexy...

Fetal bladder outlet obstruction (BOO), most commonly caused by posterior urethral valves (PUV), remains a challenging and multi-faceted condition. Evolving techniques, and refinement in ultrasound, optics and instrumentation, have increased our rate of prenatal diagnosis, and enabled valve ablation not only in smaller newborns, but also in fetuses. Long-term outcome studies have raised our awareness of the silent damage caused by bladder dysfunction and polyuria and encouraged their proactive management. In spite of our best efforts, the proportion of boys with PUV who progress to chronic and end-stage renal disease (ESRD) has not changed in the last 25 years...

PURPOSE: Prognostic information is limited on children with congenital anterior urethral valves or a diverticulum. We reviewed the literature and examined our clinical database to identify clinical features predicting a poor renal outcome, defined as azotemia, renal failure or death. MATERIALS AND METHODS: We reviewed 97 English language studies of patients 18 years old or younger. Seven patients from our institutions were also included in analysis. After data abstraction we used multivariate models to define factors associated with outcomes of interest...

Two unusual cases of anterior urethral valves (AUV) without diverticulae are presented. The first case is a male child born with prenatal diagnosis of bilateral hydronephrosis. On cystoscopy, iris-like diaphragm valves were encountered about 3 mm distal to the skeletal sphincter. In the second case, an 18-month-old male child was investigated for recurrent febrile urinary tract infections and obstructed urinary symptoms. Cystoscopy confirmed the presence of slit-like valves 5 mm distal to the skeletal sphincter...

INTRODUCTION: Although cross-trigonal ureteral reimplantation (Cohen) is a commonly used technique in children, it represents a non-physiological transfer of the ureteral orifices and may prove challenging with regard to endoscopic ureteral operations in later life. In 1964, Mathisen described an alternative method of ureteral reimplantation with lateralization of the neohiatus, creating an orthotopic course of the submucosal ureter. We have evaluated success and complication rates of both techniques that were applied sequentially at our departments...

Botulinum neurotoxin (BoNT) is used to treat a variety of ailments, and its therapeutic application in lower urinary tract disorders (LUTDs) is well studied. Robust evidence supporting the efficacy and tolerability of BoNT in the treatment of neurogenic detrusor overactivity (NDO) and non-neurogenic overactive bladder (OAB) has led to regulatory approval for these conditions. Use of BoNT in the treatment of interstitial cystitis/bladder pain syndrome, chronic pelvic pain, and detrusor sphincter dyssynergia has demonstrated some promise, but is still evolving and off-label for these indications...

Non-neurogenic lower urinary tract dysfunction (LUTD) in children is very common in clinical practice and is important as an underlying cause of lower urinary tract symptoms, urinary tract infection and vesicoureteral reflux in affected children. LUTD in children is caused by multiple factors and might be related with a delay in functional maturation of the lower urinary tract. Behavioral and psychological problems often co-exist in children with LUTD and bowel dysfunction. Recent findings in functional brain imaging suggest that bladder bowel dysfunction and behavioral and psychiatric disorders in children might share common pathophysiological factors in the brain...

Male lower urinary tract symptoms (LUTS) are prevalent in the general population, especially in those of advanced age, and are characterized by notable diversity in etiology and presentation, and have been proven to cause various degrees of impairment on quality of life. The prostate has traditionally been regarded as the core cause of male LUTS. As a result, medical treatment aims to provide symptomatic relief and effective management of progression of male LUTS due to benign prostatic enlargement. In this context, α1-blockers, phosphodiesterase-5 inhibitors, and 5α-reductase inhibitors have long been used as monotherapies or in combination treatment to control voiding LUTS...

Lower urinary tract dysfunction is an umbrella diagnosis that covers difficulty evacuating urine from the bladder. In its most simple form, it is either an inability to store urine or an inability to empty the bladder of urine appropriately. The normal and the abnormal bladder, the role of urodynamics in evaluation of lower urinary tract dysfunction, and the medical and behavioral management of some of these disorders are reviewed.

PURPOSE: Low renal parenchymal area, which is the gross area of the kidney in maximal longitudinal length minus the area of the collecting system, has been associated with increased risk of end stage renal disease during childhood in boys with posterior urethral valves. To our knowledge normal values do not exist. We aimed to increase the clinical usefulness of this measure by defining normal renal parenchymal area during infancy. MATERIALS AND METHODS: In a cross-sectional study of children with prenatally detected mild unilateral hydronephrosis who were evaluated between 2000 and 2012 we measured the renal parenchymal area of normal kidney(s) opposite the kidney with mild hydronephrosis...

INTRODUCTION: Uroflowmetry (UF) alone is often inadequate or unreliable to diagnose lower urinary tract dysfunction (LUTD). Therefore, other non-invasive tests, such as ultrasound (US), post-voiding residual volume (PVR) assessment and symptom scales, are used as well for objective definition of the problem. OBJECTIVE: The aim of this study was to investigate the possible predictive function of the non-invasive diagnostic tests for the response to treatment. STUDY DESIGN: The prospective registry data of 240 patients with LUTD, from November 2006 to September 2013, were retrospectively analyzed...
