Non-neurogenic voiding dysfunction including dysfunctional voiding and detrusor underactivity caused by a spastic or non-relaxing external urethral sphincter can theoretically be treated by injections of botulinum A toxin into the external urethral sphincter. This randomized, double-blind, placebo-controlled trial was designed to determine the clinical efficacy of onabotulinumtoxinA urethral sp...

Purpose: Children with no obvious anatomic or neurological abnormalities who present with various urinary symptoms such as urgency, frequency, incontinence or urinary tract infection (UTI) are often diagnosed as having dysfunctional voiding. However, it is likely that dysfunction voiding represents a spectrum of abnormalities with different etiologies. The purpose of this study is to correlate ...

OBJECTIVES To estimate the predictive value of diurnal voiding symptoms for the diagnosis of bladder dysfunction in enuretic children and teenagers receiving care at Fernandes Figueira Institute (Rio de Janeiro, Brazil). METHODS From June 1999 to May 2002, 91 patients (aged 5-17 years) with enuresis, both monosymptomatic and polysymptomatic, were assessed based on medical history, voiding cha...

BACKGROUND The rates reported for postoperative urinary retention following midurethral sling procedures are highly variable. Determining which patients have a higher likelihood of failing a voiding trial will help with preoperative counseling prior to a midurethral sling. OBJECTIVE The objective of the study was to identify preoperative predictors for failed voiding trial following an isolat...

BACKGROUND The aims of this study were to determine whether renal pelvis dilation on ultrasound was reliable in predicting vesicoureteral reflux (VUR) and to assess the relationship of other clinical information of VUR in children with urinary tract infection (UTI). METHODS We retrospectively reviewed clinical data, renal echo, and voiding cystourethrogram (VCUG) results in hospitalized child...

INTRODUCTION The urofacial or Ochoa syndrome is a rare disease characterized by the presence of functional obstructive uropathy associated with peculiar facial features when patients attempt to smile or laugh. Unfortunately, many of these patients remain without proper diagnosis or adequate treatment due to lack of recognition of the disease. This can ultimately result in upper tract deteriorat...

BACKGROUND Endoscopic correction of vesicoureteral reflux (VUR) in children offers minimally invasive management and is widely used as a first-line procedure for all grades of reflux. However, there is debate about which tissue-augmenting substance is the best to use. The aim of this study was to evaluate the efficacy of two bulking substances, Deflux (Dx/HA) and Vantris (PPC), for endoscopic t...

introduction: this study evaluates the accuracy of renal ultrasonography (us) in the detection of vesicoureteral reflux (vur) compared to voiding cystourethrography (vcug). methods: we retrospectively reviewed the medical records of 131 children with urinary tract infection. ultrasound findings were considered to be suggestive of vur if a “pelvocalyceal dilatation”‚ “retrovesical ureteral dilat...

UNLABELLED The AIM of the study was to validate some of the imaging criteria for voiding dysfunction in children. MATERIAL AND METHODS The study included a number of 55 children with voiding dysfunction symptoms. They were investigated clinically as well as through imaging techniques: renourinary ultrasound, voiding cystourethrography and cystometry. RESULTS The most common symptoms were ur...
