Laparoscopic Treatment of Wilms' Tumor: Criteria of SIOP-UMBRELLA Protocol may be Updated.

Introduction: Total nephrectomies for the treatment of Wilms' tumor (WT) are more and more performed by laparoscopy, although indications for this approach following the UMBRELLA guidelines are currently very restrictive.

Laparoscopic Extravesical Reimplantation in Children with Primary Obstructive Megaureter.

Conservative management of primary obstructive megaureter (POM) appears as the best option in patients with adequate ureteral drainage. Nevertheless, surgical intervention is indicated in cases of recurrent urinary tract Infections (UTIs), deterioration of split renal function, and significant obstruction. The gold standard includes: Ureteral reimplantation with or without tapering by open approach.

The children were divided in two groups according to surgical approach: group 1 underwent laporoscopic reimplantation and included 116 children (92 girls and 24 boys with a median age of 4.

Extravesical Ureteral Reimplantation Following Lich-Gregoir Technique for the Correction of Vesico-Ureteral Reflux Retrospective Comparative Study Open vs. Laparoscopy.

The aim is to compare the outcome of open versus laparoscopic Lich-Gregoir technique in patients with vesicoureteral reflux. We report a retrospective multicenter comparative study between open and laparoscopic extra-vesical ureteral reimplantation (EVUR) following Lich-Gregoir (LG) technique for the correction of Vesico-Ureteral Reflux (VUR). Between January 2007 and December 2015, 96 patients with VUR (69 females and 27 males) and deterioration of the renal function, underwent EVUR following LG technique.

Management of Polypoid Gallbladder Lesions in Children: A Multicenter Study.

Introduction:  Polypoid lesions of the gallbladder (PLG) are relatively common in adults, while they are very rare in children. The use of high-quality ultrasonography leads to increased detection of PLG, although less than 20 pediatric cases of primary PLG have been reported in the literature. The aim of this study was to address the experience of PLG management in children.

Laparoscopic extravesical ureteral reimplantation (LEVUR): a systematic review.

Background: Laparoscopic ureteral reimplantation is a feasible method for treating ureteral pathology with good preliminary results in the literature. In this study, we review medium term results for laparoscopic ureteral reimplantation and discuss current developments of this procedure.

Pyeloplasty techniques using minimally invasive surgery (MIS) in pediatric patients.

Hydronephrosis is the most common presentation of ureteropelvic junction (UPJ) obstruction. We reviewed literature, collecting data from Medline, to evaluate the current status of minimally invasive surgery (MIS) approach to pyeloplasty. Since the first pyeloplasty was described in 1939, several techniques has been applied to correct UPJ obstruction, but Anderson-Hynes dismembered pyeloplasty is established as the gold standard, to date also in MIS technique.
