[Ureteropelvic junction syndromes: antenatal diagnosis].

Seventy-four hydronephrosis by uretero-pelvic obstruction, discovered by antenatal real-time ultrasound, have been managed on sixty-one children. Three groups, with a specific management, are distinguished. The minimal forms have been only watched over (15 cases). The average forms have been operated (49 cases); considering the results (3 immediate complications and 2 early stenoses), it seems better to wait for 4 months to operate and to place a drain in renal cavities. In major forms (silent kidney on IVP), the diagnosis and therapeutic management use the percutaneous nephrostomy (10 cases). The interest of antenatal diagnosis of uretero-pelvic obstructions is to allow to operate, not only before the renal deterioration emphasizes, but principally before septic complications.

Do Emergency Department Observation Units Help Prevent Revisits for Patients with Renal Colic?

Introduction: Renal colic is generally considered a diagnosis appropriate for discharge home once pain is adequately controlled and no other admission criteria are met. The increasing prevalence of ED observation units (EDOU) represent another disposition option for patients with renal colic. In this study, we sought to describe the rates of 14-day revisits for renal colic among patients placed in an EDOU as compared to those discharged from the ED.

A case of redo pyeloplasty using robot-assisted retroperitoneoscopic pyeloplasty (RARP) for failed primary laparoscopic pyeloplasty (LP) for ureteropelvic junction obstruction (UPJO) is reported. A 12-year-old boy had LP elsewhere. He was referred for management of persistent left hydronephrosis, but was managed conservatively due to minimal symptoms and stable radioisotopic renography.

Article Synopsis
  • Implementation of the Enhanced Recovery After Surgery (ERAS) protocol for pediatric Laparoscopic Pyeloplasty (LP) highlighted obstacles and outcomes of managing ureteropelvic junction obstruction (UPJO).
  • The study collected and analyzed clinical data from 107 patients before and after implementing the ERAS, showing significant improvements in recovery times and reduced need for pain management.
  • Success factors included pre-surgery planning, team communication, and education, suggesting that increased compliance with ERAS could further enhance patient outcomes and minimize hospital stays.

Background: The study aimed at evaluating the role of thiol-disulphide balance parameters [native thiol (SH), total thiol (SH + SS), disulphide (SS), disulphide/native thiol ratio (% SS/SH), disulphide/total thiol ratio (% SS/Total Thiol) and native thiol/total thiol ratio (%SH/Total Thiol)], which are important oxidative stress markers in the congenital ureteropelvic junction (UPJ) stenosis, in the diagnosis of the disease, and its role in determining the need for surgery and follow-up.

Materials And Methods: This prospective study included 30 children diagnosed with congenital intrinsic ureteropelvic junction obstruction (UPJO) and a control group of 30 healthy children admitted to the pediatric clinic between January 2016 and February 2017. The children with UPJO underwent laparoscopic dismembered pyeloplasty.
