In patients with posterior urethral valves (PUV), severe unilateral vesicoureteral reflux (VUR) is one of the three conditions associated with preservation of renal function. Others are urinary ascites or urinoma in newborns and large congenital bladder diverticula. These conditions most likely provide a pop-off mechanism preventing the development of high intravesical pressure. Only 5% of pati...

Urinary tract infection is a common and frequently recurring condition in children. The susceptibility of the host, the presence of urinary tract abnormalities, and the virulence of the urinary pathogens are of primary importance in the development of the infection. Renal parenchymal scarring, hypertension, and renal insufficiency are well-established complications of the infection in children....

The endoscopic STING procedure using Deflux is a common and minimal invasive treatment for vesicoureteral reflux. Herein we present the case of an 11-year-old girl with loin pain and de novo hydronephrosis and megaureter on the left. Ultrasound and plain abdominal X-ray demonstrated a calcification at the ureterovesical junction. She had been treated with Deflux injections 5 years before. The c...

Since the U.S. Food and Drug Administration approved dextranomer/hyaluronic acid copolymer (Deflux) for the treatment of vesicoureteral reflux, endoscopic injection therapy using Deflux has become a popular alternative to open surgery and continuous antibiotic prophylaxis. Endoscopic correction with Deflux is minimally invasive, well tolerated, and provides cure rates approaching those of open ...

The endoscopic injection of vesicoureteric orifices with synthetic or natural materials is a widely recognized method of treating vesicoureteral reflux (VUR). The aim of this study is to present two cases of clinically significant complications following the use of dextranomer/hyaluronic acid copolymer, which led to the progression of the reflux degree, permanent infection of the urinary tract,...

Vesicoureteral reflux (VUR), the retrograde flow of urine from the bladder toward the kidney, is congenital and often familial. VUR is common in childhood, but its precise prevalence is uncertain. It is about 10–20% in children with antenatal hydronephrosis, 30% in siblings of patient with VUR and 30–40% in children with a proved urinary tract infection (UTI). Ultrasonography is a u...

INTRODUCTION The hypothesis derives from the field of female stress incontinence. Application of pressure on the anterior vaginal wall at midurethra with a hemostat restores the geometry of the vesicoureteral junction and continence. METHODS We applied unilateral midurethral pressure during a radiological investigation of a 15-year-old female patient who had undergone 2 surgeries for ureteric...

PURPOSE Children with lower urinary tract dysfunction and vesicoureteral reflux, at cystography assessment, frequently present alterations in the lower urinary tract anatomy such as dilated posterior urethra, irregularity of the bladder wall and diverticula. However, the significance of these findings is unknown. The objective of this study is to evaluate the incidence of these findings, their ...

Classic anti reflux procedures on children with a history of posterior urethral valve does not usually yield good results and often ends up with ureteral obstruction and even permanent urinary diversion. From 1981 through 1988,21 boys with history of posterior urethral valve (PUV) underwent evaluation for vesicoureteral (VU) reflux; 17 boys had VU reflux. Following valve ablation, reflux disapp...
