Endoscopic balloon dilation of primary obstructive megaureter: is fluoroscopic guidance necessary?

Objective: To compare the long-term effectiveness, complications, and outcomes of primary obstructive megaureter (POM) treated by endoscopic balloon dilation under fluoroscopic guidance versus not using radioscopy during the procedure.

Patients And Methods: A comparative study between POM cases treated at our institution by endoscopic balloon dilation (EBD) under fluoroscopic guidance (FG) (n = 43) vs no fluoroscopic guidance (NFG) (n = 48) between the years 2004 and 2018 was conducted. The procedure in FG consisted of performing a retrograde pyelography before dilation.

Long Term Outcome of 112 Pediatric Patients With Ureteroplevic Junction Obstruction Treated by Endourologic Retrograde Balloon Dilatation.

Purpose: To analyze the effectiveness, complications and long-term outcome of the patients with ureteropelvic junction obstruction (UPJO) treated by endoscopic retrograde balloon dilatation (ERBD) in the largest series reported.

Materials And Methods: Between years 2004 and 2018, 112 patients with primary unilateral UPJO were treated by ERBD. Endoscopic treatment consisted on a retrograde balloon dilatation of the ureteropelvic junction (UPJ), through cystoscopy and under fluoroscopic guidance, using high-pressure balloon catheters.

Surgical approach to prune-belly syndrome: A review of our series and novel surgical technique.

Introduction: Surgical management of children with Prune-belly syndrome (PBS) can be divided into three categories: urinary tract reconstruction, abdominal wall reconstruction, and orchidopexy. Adequate repair of the abdominal wall by abdominoplasty at an early age, allows an adequate aesthetic appearance, but also allows a correct development of walking, breathing, defecation and urination.

Objective: To present a novel surgical technique for abdominal wall reconstruction, which combines plication with complete overlap of the fascia and neoumbilicoplasty with an island flap rotated on itself.

Micro-Ureteroscopy as a Treatment of Renal Pelvis Lithiasis in Young Children.

Miniaturization of endoscopic instruments has allowed to improve the efficacy of kidney stone treatment in young children. Aim of the study is to evaluate the usefulness of microureteroscopy with 4.85F sheath in the treatment of renal stones in children.

Endourologic Treatment in Two Cases of Ureteral Valves.

Congenital ureteral valves are a rare cause of ureteral obstruction that may lead to renal function deterioration. We present two clinical cases treated endoscopically by monopolar electrocautery and laser fiber ablation. The first case is a 13-year-old male with several episodes of abdominal pain and was found to have severe left hydronephrosis.

Micropercutaneous endopyelotomy for the treatment of secondary ureteropelvic junction obstruction in children.

Introduction: The management of recurrent pyeloureteral junction obstruction (PUJO) is controversial, as there is no suitable technique for its correction. Percutaneous endopyelotomy shows better results in recurrent PUJO compared to primary PUJO. Micro-percutaneous approaches reduce damage to renal parenchyma and facilitate access to renal pelvis.

Long-Term Outcomes in Primary Obstructive Megaureter Treated by Endoscopic Balloon Dilation. Experience After 100 Cases.

To assess long-term effectiveness, complications, and outcomes of primary obstructive megaureter (POM) treated by endoscopic balloon dilation (EBD) in the largest series reported. Hundred POM in 92 consecutive patients were treated by EBD between years 2004 and 2016. A total of 79 POM (73 patients) with more than 18 months of follow-up after treatment have been analyzed.

Urethral Triplication Without Bladder Duplication: Endourologic Diagnosis and Management.

Urethral triplication is a rare congenital anomaly of the lower urinary system, with <15 cases reported so far. We present a 24-month-old boy with accessory hypoplastic urethra ending in glans. At the beginning of toilet training, urine output was observed along the rectum.

Endoscopic Urinary Diversion As Initial Management of Symptomatic Obstructive Ectopic Ureter in Infants.

Aim: Definitive surgery of ectopic ureter in infants is challenging. We propose an endoscopic urinary diversion (EUD) as a novel surgical technique in the initial management of symptomatic obstructive ectopic ureter.

Patients And Methods: Sixteen obstructive ectopic ureters (14 patients) were initially treated by EUD between 2006 and 2015.

Retrograde Endopyelotomy with Cutting Balloon™ for Treatment of Ureteropelvic Junction Obstruction in Infants.

Purpose: The aim of this study is to analyze results of retrograde endopyelotomy with cutting balloon for treatment of ureteropelvic junction obstruction (UPJO) in infants.

Methods: We routinely treat patients with UPJO under 18 months of age with retrograde high-pressure balloon dilatation of the pelviureteric junction (PUJ). During the procedure, in these cases where narrowing at the PUJ persists, endopyelotomy with cutting balloon is performed.

High-pressure balloon assessment of pelviureteric junction prior to laparoscopic "vascular hitch".

Aim: To assess if calibration of the ureteropelvic junction (UPJ) using a high-pressure balloon inflated at the UPJ level in patients with suspected crossing vessels (CV) could differentiate between intrinsic and extrinsic stenosis prior to laparoscopic vascular hitch (VH).

Materials And Methods: We reviewed patients with UPJO diagnosed at childhood or adolescence without previous evidence of antenatal or infant hydronephrosis (10 patients). By cystoscopy, a high-pressure balloon is sited at the UPJ and the balloon inflated to 8-12 atm under radiological screening.

Primary obstructive megaureter: the role of high pressure balloon dilation.

Background And Purpose: There is a growing interest in minimally invasive treatment of primary obstructive megaureter (POM) in children. The absence of long-term follow-up data, however, makes it difficult to establish the indication for an endoscopic approach. The aim of our study is to determine the long-term efficacy of endourologic high-pressure balloon dilation of the vesicoureteral junction (VUJ) in children with POM that necessitates surgical treatment.

Management of ureteropelvic junction obstruction with high-pressure balloon dilatation: long-term outcome in 50 children under 18 months of age.

Objective: To analyze the usefulness of dilatation in the treatment of ureteropelvic junction obstruction (UPJ) in children <18 months of age, including newborns and infants.

Methods: Patients (n = 50; <18 months of age) were diagnosed using abdominal ultrasound, cystogram, and diuretic renography. Treatment was with endourologic retrograde balloon dilatation under fluoroscopic guidance.

Is intraoperative surgeon's opinion an accurate tool to assess the outcome of endoscopic treatment for vesicoureteral reflux?

Objective: Our experience in the endoscopic treatment of vesicoureteral reflux (VUR) has significantly increased during the last decade. To help develop diagnostic tests to check the success of this procedure, we evaluated the accuracy of surgeons' intraoperative observations as a predictor of treatment results.

Method: We performed a prospective study of patients with VUR who were endoscopically treated during 1 year (106 renal units).

Percutaneous endopyelotomy with electrocautery: modified techniques in the treatment of ureteropelvic junction obstruction in a child under 2 years.

Objective: In recent years new techniques in minimally invasive treatment of congenital stenosis of ureteropelvic junction have been developed. We report the treatment of pyeloureteral stenosis in children by percutaneous endopyelotomy.

Methods: In the work up study of a child (18 months) with abdominal palpable mass, a severe left hydronephrosis with a renal pelvis diameter of 65 mm and severely thinned renal parenchyma was found.

Endourological management in a newborn with incomplete bladder duplication.

We report an unusual case of a newborn with incomplete bladder duplication and a complete sagittal septum. This malformation was associated with dysplasia of the right kidney, right cryptorchidism, single urethra, and no other genital or gastrointestinal anomalies. At birth, we found severe ureterohydronephrosis in a solitary left kidney caused by the collapse of the left bladder when the right bladder was filled.
