Unilateral multicystic dysplastic kidney in infants exposed to antiepileptic drugs during pregnancy
2007
Prenatal exposure to antiepileptic drugs (AEDs) increases the risk of major congenital malformations (MCM) in the fetus. AED-related abnormalities include heart and neural tube defects, cleft palate, and urogenital abnormalities. Among the various congenital anomalies of the kidney and urinary tract (CAKUT), multicystic dysplastic kidney (MCDK) disease is one of the most severe expressions. Although prenatal ultrasound (US) examination has increased the prenatal diagnosis of MCDK, the pathogenesis is still unclear. We report on four cases of MCDK in infants of epileptic women treated with AEDs during pregnancy. From October 2003 to June 2006, we observed four infants with unilateral MCDK bo…
The fate of implant after endoscopic injection of dextranomer/hyaluronic acid in vesicoureteral reflux: time to partial reabsorption and stabilization
2020
Summary Background/introduction Vesicoureteral reflux (VUR) potentially leads to renal damage, scarring, and eventually end-stage renal disease. Endoscopic treatment is well tolerated in children, it has reduced costs, and it effectively prevents urinary tract infections (UTIs), while avoiding long term antibiotics use. Objective With the aim to investigate the time needed to reach the stabilization of the dextranomer/hyaluronic acid (Dx/HA) implants and to identify cut-off heights to ensure the success of the procedure, the authors analyzed ultrasonographic (US) intra-operative appearance of the mounds following endoscopic treatment for VUR and repeated the measurements during serial posto…
A giant fetal urinoma in a neonate without detectable obstructive uropathy
2003
UNLABELLED Fetal urinoma is an uncommon finding in prenatal investigations. Most previous reports have, almost in every case, referred to the presence of an obstructive uropathy and thus to very high pressure in the upper urinary tract during fetal life. In this paper we present a prenatally detected fetal giant urinoma occurring in the absence of an apparent obstructive uropathy but associated with an ipsilateral vesico-ureteral reflux. CASE REPORT A 5-day-old boy, born after a caesarean section in the 37th week of gestation, but without any perinatal distress, came under our observation because of the evidence of a right upper quadrant abdominal mass. This mass had already been detected p…
Correction of vesicoureteral reflux: where do we stand?
2004
Purpose of review Newer techniques of molecular biology allow us to gain a better understanding of the molecular mechanism of primary urinary reflux. In recent years, diagnostic tools and treatment options for vesicoureteric reflux have dramatically changed. In this review, we want to focus on genetics, molecular biology, histology, clinical findings, diagnostic tools and newer surgical techniques for the treatment of vesicoureteric reflux published between 2003 and March 2004. Recent findings Recent findings have demonstrated that the renin-angiotensin-aldosterone system does not seem to be responsible for the development of primary vesicoureteric reflux. Echo-enhanced ultrasound with cont…
Ultrasonographic mound height as predictor of vesicoureteral reflux resolution after endoscopic treatment in children
2016
Purpose: Endoscopic dextranomer/hyaluronic acid copolymer (Dx/HA) injection is a safe and efficacious treatment option for vesicoureteral reflux (VUR) in children. Endoscopic appearance, hydrodistention and amount of injected Dx/HA have been demonstrated not to be reliable predictors of outcome. Aim of this study was to evaluate Dx/HA mounds on ultrasound scans (US) and find out any eventual correlation with reflux resolution. Methods: We selected patients treated with endoscopic injection for moderate to high VUR, renal scaring or repeated infections under antibiotic prophylaxis. Success was defined by absence of VUR at control 3. months after surgery; at 3. months we also measured mound h…
Intraoperative ultrasound-assisted approach for endoscopic treatment of vesicoureteral reflux in children
2017
Purpose Despite minimal invasiveness and high success rate, guidelines still prescribe voiding Cystourethrogram (VCUG) after endoscopic treatment for vesicoureteral reflux (VUR) in children. The aim of this paper was to analyze whether intraoperative ultrasound (IO-US) could improve surgical accuracy and perioperative counseling, thus potentially decreasing the need for postoperative VCUG. Methods We selected children treated for moderate to high grade VUR, renal scarring or repeated infections under antibiotic prophylaxis from January to December 2015. Endoscopic injection was combined with IO-US to detect optimal needle placement and to guide mound formation. IO-US findings were compared …
Presentation, Management and Long-Term Outcome of Ureteropelvic Junction Obstruction in Duplex Kidneys.
2015
Ureteropelvic junction obstruction in association with a duplex collecting system is a rare but challenging upper urinary tract pathology. We report our 21-year experience with this anomaly in terms of presentation, diagnostic evaluation and management.We retrospectively identified all patients with ureteropelvic junction obstruction in a duplex collecting system between 1991 and 2012. We reviewed each case for presenting symptoms, anatomy and management. Median followup was 10.8 years (range 2 to 22).Ureteropelvic junction obstruction in duplex kidneys was diagnosed in 21 patients. Ten patients presented with clinical symptoms such as flank pain and urinary tract infection but 11 were asym…
