Combination of robot‐assisted laparoscopic pyeloplasty for lower moiety ureteropelvic junction obstruction in a partial duplex system and percutaneous endoscopic surgery for renal calculi reusing the port for robotic pyeloplasty

IJU Case Reports, 2023
Introduction Ureteropelvic junction obstruction is often associated with renal calculus formation. However, there is no report of using robot‐assisted laparoscopic pyeloplasty combined with percutaneous endoscopic surgery for ureteropelvic junction ...

Hsa_circRNA_0045861 promotes renal injury in ureteropelvic junction obstruction via the microRNA-181d-5p/sirtuin 1 signaling axis

Annals of Translational Medicine, 2021
Background Ureteropelvic junction obstruction (UPJO) is one of the most common causes of hydronephrosis in children. This study explored the effects and the regulatory mechanisms of the circular RNA (circRNA) hsa_circRNA_0045861 (circRNA_0045861) in UPJO.

Clinical and radiographic outcomes following salvage intervention for ureteropelvic junction obstruction

International Brazilian Journal of Urology, 2021
Purpose: We aimed to assess failure rates of salvage interventions and changes in split kidney function (SKF) following failed primary repair of ureteropelvic junction obstruction (UPJO). Materials and Methods: A retrospective review of adult patients at

Laparoscopic pyeloureterostomy for ureteropelvic junction obstruction occurring in incomplete ureteral duplication of the solitary kidney

IJU Case Reports, 2021
Introduction Ureteropelvic junction obstruction associated with ureteral duplication is rare, with prevalence reported to be around 2–7%. Ureteropelvic junction obstruction of the lower pole with both complete and incomplete duplex systems is a common ...

Robot-assisted excision of partially obstructing ureteral fibroepithelial polyp in a child: A case report and review of the literature

Journal of Pediatric Surgery Case Reports, 2022
Background: Fibroepithelial polyps are benign tumors located in the upper ureter and ureteropelvic junction. Given their location in rare cases they can cause hydronephrosis.

Variations in the Density and Distribution of Cajal Like Cells Associated With the Pathogenesis of Ureteropelvic Junction Obstruction: A Systematic Review and Meta-Analysis

Frontiers in Surgery, 2021
Introduction: Cajal like cells (CLCs) in the upper urinary tract have an ability to generate coordinated spontaneous action potentials and are hypothesized to help propel urine from renal pelvis into the ureter.

More than meets the eye: intra-operative retrograde pyelography when more than one ureteral obstruction is suspected – A case report

Journal of Pediatric Surgery Case Reports, 2023
Background: Antenatal hydronephrosis can be caused by various congenital anomalies of the excretory urinary system. Common causes are isolated ureteropelvic junction obstruction and ureterovesical junction obstruction with isolated mid-ureteral stenosis ...

Renal Cortical Thickness After Pyeloplasty in Pediatric Ureteropelvic Junction Obstruction

Research and Reports in Urology, 2021
Purpose The main goal of pyeloplasty is to maintain or improve renal function. Diuretic renography is the gold standard for evaluating renal function after pyeloplasty. Renal ultrasonography (RUS) is commonly used to determine hydronephrosis in pediatric
