INTRODUCTION Over the last two decades, minimally invasive treatment options for ureteropelvic junction obstruction have been developed and are bcoming more popular. Multiple series of laparoscopic pyeloplasty have demonstrated high success rates and low perioperative morbidity in pediatric and adult populations, for both the transperitoneal and retroperitoneal approaches. In this review, we ai...

PURPOSE The minimally invasive treatment of ureteropelvic junction obstruction has evolved during the last decade from endoscopic to laparoscopic and robotic. We review our 10-year experience with ureteropelvic junction obstruction, and report on our experience and followup. MATERIALS AND METHODS We reviewed all patients treated during the last 10 years. There were 294 procedures performed wi...

PURPOSE Since the first laparoscopic pyeloplasty was described in a child in 1995, there have been several reports of pyeloplasty in older children. However, to date there have been few reports of laparoscopic pyeloplasty in infants and toddlers. The aim of this study was to evaluate the results of laparoscopic pyeloplasty in children younger than 2 years. MATERIALS AND METHODS All laparoscop...

We read with interest the article by Xie et al. (1) in a previous issue of Nephro-Urology Monthly (October 2011), regarding the comparison between intravenous urography and computed tomography urography in diagnosing ureteropelvic junction obstruction. As previously described, pathological lesions at the ureteropelvic junction are classified into intrinsic and extrinsic abnormalities. In the ca...

INTRODUCTION Nephrolithiasis is a multifactorial disease related to genetic disorders and environmental factors. Kidney stones are more common in adults and are associated with several metabolic and anatomical disorders. The major anatomical abnormalities, such as obstruction of the ureteropelvic junction, horseshoe kidney, complete or incomplete duplicated ureter, bifid pelvis, and medullary s...

We report two adult cases of congenital ureteropelvic junction obstruction detected incidentally in the setting of blunt abdominal trauma. CT images are provided to describe the presentation, while review of the literature and management of renal trauma are discussed.

We present a rare case of an unobstructed dilated renal pelvis in a newborn female. Prenatal imaging documented a large abdominal cyst in a stable fetus. Postnatal imaging confirmed persistence of this large cyst but with an unclear etiology. The child was taken to surgery by the pediatric surgeons with concern for a possible harmful nonurologic diagnosis. Intraoperative findings were that of a...

Pyeloplasty is the gold standard therapy for ureteropelvic junction obstruction. Robotic assisted pyeloplasty has been widely adopted by urologists with and without prior laparoscopic pyeloplasty experience. However, difficult situations encountered during robotic assisted pyeloplasty can significantly add to the difficulty of the operation. This paper provides tips for patient positioning, por...
