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.

Non-contrast-enhanced MR angiography using time-spin labelling inversion pulse technique for detecting crossing renal vessels in children with symptomatic ureteropelvic junction obstruction: comparison with surgical findings.

Objectives: Investigate the feasibility and evaluate the accuracy of non-contrast-enhanced MR angiography (NC-MRA) using time-spin labelling inversion pulse (time-SLIP)to identify crossing renal vessels (CRVs) in children requiring surgical treatment of ureteropelvic junction (UPJ) obstructionand compare to laparoscopic findings.

Materials And Methods: Nineteen children ranging from 6 to 16 years of age underwent NC-MRA using the time-SLIP technique before surgery. Two independent readers analysed the MRA images.

Fetal ovarian cysts management and ovarian prognosis: a report of 82 cases.

Background/purpose: Fetal ovarian cysts are frequently complicated by intracystic hemorrhage without associated clinical signs, which is often secondary to ovarian torsion leading to loss of the ovary. The aim of this study was to evaluate ovarian outcome and the place of prenatal management and surgery in the first few days of life in order to save the ovary.

Methods: Between January 1987 and June 2006, 82 fetal ovarian cysts in 79 patients were managed and clinically and ultrasonographically followed up for several months (median, 11 months; range, 6 months to 10 years) in all of the cases where the ovary was not removed.
