BACKGROUND: Ureterocalicostomy is indicated mainly in cases with failed pyeloplasty or with a completely intrarenal pelvis. While there have been several case series reported in adults, laparoscopic ureterocalicostomy in pediatric cases has rarely been reported. We report a case of pure laparoscopic ureterocalicostomy for ureteropelvic junction obstruction in an Asian female child. CASE PRESENTATION: A 10-year-old female patient was referred to our hospital due to right high-grade hydronephrosis and a right renal stone, which was detected due to hematuria...

INTRODUCTION: Ureterocalicostomy (UC) is a well-established treatment option for patients with recurrent ureteropelvic junction obstruction (UPJO) with postoperative fibrosis and a relatively inaccessible renal pelvis. This study aimed to evaluate the long-term outcome of UC and factors predicting its failure. MATERIALS AND METHODS: We retrospectively analysed data of 72 patients who underwent open or laparoscopic UC from 2000 to 2014. Variables that may affect the outcomes of UC were assessed with regard to primary pathology, age, serum creatinine, preoperative renal size (<15 cm and > 15 cm), renal cortical thickness (<5mm and >5 mm), grade of hydronephrosis and preoperative renal function (GFR < or >20 ml/min)...

Robotic upper urinary tract reconstruction (UUTR) has been widely utilized for surgical management of congenital obstruction. To further reduce morbidity and simplify postoperative care, outpatient robotic pyeloplasty (RP) and robotic ureteroureterostomy (RUU) were performed without ureteral stents, drains, or urethral catheters. The aim of the study was to assess the safety of performing tubeless robotic UUTR as an outpatient procedure. A retrospective review was performed for patients who underwent outpatient tubeless RP and RUU between July 2015 and January 2017...

OBJECTIVE: To report our experience on gas endoscopy as the first step of pelvi-ureteric junction (PUJ) obstruction repair when complicated by nephrolithiasis. MATERIALS AND METHODS: Stone formation due to urine stasis is a known complication PUJ obstruction and an indication for its surgical repair. The undisputed results of the Anderson-Hynes dismembered pyeloplasty make it a quasi-gold standard; however, the identification and extraction of calyceal stones through the laparoscopic route can be challenging...

OBJECTIVES: Uretero-pelvic junction (UPJ) obstruction has been classically treated by open dismembered pyeloplasty. Recently, laparoscopic (LP) and robotic pyeloplasty (RP) have become the techniques of choice for the treatment of UPJ stenosis in adult and pediatric population. Our objective in this paper is to review the results of minimally invasive surgery as the treatment of UPJ obstruction, the trend to use these approaches and the current limits of LP and RP. METHODS: A review of most relevant papers and meta-analysis about LP and RP in pediatric and adult population was performed using PubMed...

BACKGROUND: MAG3 diuretic renal scan remains the gold standard for determination of improvement in renal drainage following pyeloplasty for ureteropelvic junction obstruction. We hypothesized that (i) a change in geometric measurements between pre-operative and post-operative renal ultrasound (RUS) images and (ii) blinded simple visual review of images both would predict pyeloplasty success. OBJECTIVE: To determine if simple visual review and/or novel geometric measurement of renal ultrasounds can detect pyeloplasty failure...
