INTRODUCTION: Endoscopic injection of a bulking agent is a common first-line approach to the treatment of vesicoureteral reflux (VUR). While early outcomes are comparable to open ureteroneocystotomy, 5-25% of children will eventually develop recurrent reflux necessitating repeat injections or open ureteral reimplantation. OBJECTIVE: To determine whether prior endoscopic injection of a bulking agent impacts outcomes of subsequent open ureteral reimplantation. STUDY DESIGN: Using a retrospective cohort design, radiographic and clinical outcomes of open ureteral reimplantation were compared between patients with and without prior endoscopic correction of reflux...

Lower urinary tract abnormalities are difficult to resolve in pediatric kidney transplant patients. Measure of residual urine, voiding cystourethrography, retrograde urethrography, cystometry, electromyography of urethral external sphincter muscle, urethrometry, and uroflowmetry are the primary methods for evaluation of lower urinary tract abnormalities. Endoscopic resection or ablation of urethral valves is required in children with posterior urethral valve to treat obstruction, but bladder function does not always recover and may deteriorate to end-stage renal failure even after the obstruction is released...

INTRODUCTION: Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele. CASE PRESENTATION: We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy...

A 59-year-old man with a medical history of hypertension, gout and obesity presented to the hospital with a chief complaint of worsening scrotal oedema. The patient endorsed associated symptoms of decreased force of stream on urination, stranguria and hesitancy with slight dysuria. Physical exam showed an effaced umbilicus and phallus with a hidden scrotum estimated to be 30×20×30 cm in size. Imaging and lab findings led to a diagnosis of total bladder herniation within an incarcerated right inguinal hernia...

Congenital anomalies of the kidney and urinary tract (CAKUT) are among the most common developmental defects in humans. Despite of several known CAKUT-related loci ( HNF1B , PAX2 , EYA1 , etc.), the genetic etiology of CAKUT remains to be elucidated for most patients. In this study, we report that disruption of the Holliday Junction resolvase gene Gen1 leads to renal agenesis, duplex kidney, hydronephrosis, and vesicoureteral reflux (VUR) in mice. GEN1 interacts with SIX1 and enhances the transcriptional activity of SIX1/EYA1, a key regulatory complex of the GDNF morphogen...

PURPOSE OF REVIEW: Significant variance exists in the management of duplex collecting system ureteroceles (DSU). There is a great spectrum in classification, management, and surgical interventions. The practice of performing bladder level operations for vesicoureteral reflux (VUR) and trigonal anatomic distortion, either after ureterocele puncture or in a single setting, has come into question as to whether all DSU patients require it. In this review, we sought to discuss DSU management trends and the need for bladder reconstruction in these patients, as well as to describe our institution's practices...

OBJECTIVES: The purpose is to determine the effects in urinary tract of a new antireflux biodegradable ureteral stent. MATERIAL AND METHODS: Thirty six ureters belonging to 24 pigs were used. The study began with an endoscopic, nephrosonographic and fluoroscopic assessment. Three study groups of n=12 ureters were then specified. In Group I, a biodegradable antireflux stent (BDG-ARS) was inserted in the right ureter of 12 pigs. Group II was comprised by the left ureter of the same animals, in which a double pigtail stent was placed for 6 weeks...

INTRODUCTION: Debris within the bladder is commonly seen on ultrasound. The etiology of bladder debris is varied and the likelihood that urinary debris represents positive urine culture is under investigation. We hypothesize that bladder debris will increase the likelihood that a urine culture is positive compared to those without bladder debris. METHODS: We performed a retrospective review on children aged 0-17 years who had a voiding cystourethrogram with a catheterized urinalysis or urine culture, and who also had a renal and bladder ultrasound up to 1 week prior, the day of, or up to 2 days after their urine studies...

Morphological and morphometric assessment of the elements of the ureterovesical junction in children was performed in the present study in different age groups ranging from 24 weeks of gestation to 16 years old. We tried to answer the question whether, in human ontogenesis, there is a period of anatomical predisposition to primary vesicoureteral reflux. The study included 210 urinary bladders with juxtavesical parts of the ureters that had been obtained from routine autopsies. As a result of the study, we showed that provided the pregnancy is uncomplicated there is no inherited susceptibility that would account for reducing or disturbing the development of ureterovesical junction elements...
