Unique Variants of Megacalycosis on Magnetic Resonance Urography.
Urology
December 2024
Department of Pediatric Urology, Emory University and Children's Healthcare of Atlanta, Atlanta, GA.
Objective: To present a unique set of patients diagnosed with megacalycosis by magnetic resonance urography (MRU) to re-evaluate the definition of megacalycosis and provide a new perspective on diagnosis and treatment.
Materials And Methods: A retrospective chart review of patients with megacalycosis as diagnosed by MRU was conducted. MRU was performed to determine the presence of obstruction, further visualize renal anatomy, and clarify the presence of megacalycosis.
Pathological characteristics analysis of children with intermittent and persistent hydronephrosis due to uretero-pelvic junction obstruction.

July 2024
Department of Urology, Children's Hospital, Capital Institute of Pediatrics, Beijing, China.
Objective: To analyze from a pathological perspective the differences between intermittent and persistent hydronephrosis in children with uretero-pelvic junction obstruction.
Methods: 23 children who underwent unilateral dismembered pyeloplasty (Anderson-Hynes operation) for intermittent hydronephrosis from September 2017 to March 2024 were included in the observation group. They were compared with a control group consisting of 23 children with persistent hydronephrosis matched for age, gender, and affected side.
Long-term outcome of retroperitoneoscopic one-trocar-assisted pyeloplasty: a single-center and single-surgeon experience.

Vinmec Research Institute of Stem Cell and Gene Technology, Vinmec Health Care System, Vinmec Times City, Minh Khai, Hanoi, Vietnam.
Purpose: The aim of this study was to assess the long-term outcomes of retroperitoneoscopic one-trocar-assisted pyeloplasty (OTAP) for ureteropelvic junction obstruction (UPJO) in children.
Methods: This retrospective analysis included 70 pediatric cases, all under the age of 5, diagnosed with UPJO and treated with the OTAP technique between May 2011 and June 2013 by a single surgeon. A single 10 mm operative scope with a 5 mm working channel was utilized to mobilize the ureteropelvic junction (UPJ) and exteriorize it through the trocar insertion site.
Robotic pyeloplasty: Technological global panacea or geo-surgical nightmare?

Article Synopsis
- Pelvi-ureteric junction obstruction (PUJO) is a condition that hinders urine flow at the junction where the kidney's pelvis connects to the ureter, affecting both adults and children.
- The obstruction can be caused by either external pressure or blockages within the body that impact urinary drainage.
- Traditionally, surgical intervention has been the primary treatment, with the open Anderson-Hynes dismembered pyeloplasty being the standard procedure for correcting this issue.
Repositioning of Ureteropelvic Junction in Robot-assisted Laparoscopic Pyeloplasty.
Urology
February 2024
Affiliated with the Sackler School of Medicine, Tel Aviv University, Tel Aviv, Israel; Department of Urology, Meir Medical Center, Kfar Saba, Israel.
Objective: To describe the technique of ureteropelvic junction (UPJ) repositioning in robot-assisted dismembered pyeloplasty as a modified approach during which the UPJ is brought to a new location to facilitate the anastomosis.
Materials And Methods: Retrospective review of pediatric and adult cases of robot-assisted laparoscopic pyeloplasty performed between the years 2016 and 2022. In a select group of patients, repositioning of the UPJ was performed.
