Purpose: This study aims to assess the long-term outcomes of robotic-assisted laparoscopic pyeloplasty (RALP) for the treatment of ureteropelvic junction obstruction (UPJO) in infants under 3 months of age, and to compare these outcomes with those of infants aged 3-12 months.
Materials And Methods: A retrospective cohort analysis was performed on 226 infants who underwent RALP between March 2017 and December 2021. Patients were stratified into two groups: Group A (aged <3 months, n = 114) and Group B (aged 3-12 months, n = 112).
Background: The treatment of complicated ureteropelvic junction obstruction (UPJO) is challenging. We introduce robot-assisted pedicled colonic flap pyeloplasty (RA-PCFP) for the treatment of complicated UPJO.
Methods: Fourteen patients (eleven females, three males) who underwent RA-PCFP between December 2020 and November 2023 at our center were included.
Background: Ureteropelvic junction obstruction (UPJO) with renal calculi is a common cause of renal impairment in pediatric patients. Surgical intervention, including laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP) combined with flexible ureteroscopy, are frequently employed to address both the obstruction and stones. This study aims to compare the safety and efficacy of RALP and LP combined with flexible ureteroscopy in treating pediatric UPJO with renal calculi.

Succinate is an important intermediate metabolite involved in inflammatory responses and various diseases. However, the precise pathogenic mechanisms of succinate in obstructive nephropathy remain to be elucidated.

Patients And Methods: This retrospective cohort study included 224 patients with hypospadias who underwent placement with DCUS (group DCUS), FC (group FC), and GT (group GT) after hypospadias repair between August 2019 and June 2023. The occurrence of early and late complications was assessed.
Purpose: This study aims to evaluate the long-term outcomes of the Hui-Jing technique (lingual mucosa combined with longitudinal preputial island flap onlay urethroplasty and tubularized incised plate glansplasty), a one-stage surgical technique developed by Dr. Huixia Zhou and Dr. Weijing Ye for the severe primary hypospadias repair, focusing on evaluating complication rates, functional success, and cosmetic satisfaction with comparisons to the two-stage Bracka technique.

Methods: Retrospective review of patients who underwent laparoscopic or robotic AOU for CPU between 2010 and 2020. Patient characteristics, perioperative surgical data, and follow-up data are described.
Renal fibrosis is a common mechanism leading to kidney failure in chronic kidney diseases (CKDs), including obstructive nephropathy (ON). Dysregulated inflammation is central to the development of renal fibrosis, but how local immune cells within the tissue microenvironment integrate and coordinate to drive this condition remains largely unknown. Herein, we documented that neutrophils were abundantly recruited and expelled neutrophil extracellular traps (NETs) in human and mouse fibrotic kidneys.

Materials And Methods: A retrospective analysis was conducted on 48 children with VUR who underwent unilateral or bilateral RALUR-EV between June 2018 and December 2022. Patients were divided into two groups: Group A (25 infants under one year) and Group B (23 children over one year).
Background: The intake of dietary antioxidants and glycolipid metabolism are closely related to chronic kidney disease (CKD), particularly among individuals with abdominal obesity. Nevertheless, the cumulative effect of multiple comorbid risk factors on the progression and complications of CKD remains inadequately characterized.
Methods: This study analyzed data from the National Health and Nutrition Examination Survey (NHANES) dat abase (2005-2018), to examine potential factors related to CKD, including glycolipid metabolism, dietary antioxidant intake, and pertinent medical history.
Objective: The objective of this study is to introduce a novel technique of robotic-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction obstruction (UPJO) with long proximal ureteral stricture in children.
Materials And Methods: Clinical information on patients who underwent a modified RALP between July 2018 and May 2019 in our center was collected retrospectively. Our surgical modifications mainly include "double-flap" tailoring of the renal pelvis and anastomosis of spatulate ureter with the double-flap.

Purpose: To describe a novel modification of technique to improve efficacy of robot-assisted laparoscopic extravesical ureteral reimplantation (RALUR-EV) in infants.
Materials And Methods: Between April 2017 and July 2019, sixteen infants with primary obstructive megaureter (POM) (Age range: 4-12 months) underwent robot-assisted ureteral reimplantation were reviewed in this series. In addition to the conventional Lich-Gregoir technique, the detrusor tunnel has been extended to the mobilized anterior bladder wall to guarantee sufficient tunnel length/ureter diameter ratio and avoid ureteral angulation.
To present our preliminary experiences of robot-assisted laparoscopic radical or partial cystectomy for bladder/prostate rhabdomyosarcoma (B/P RMS) in children. A retrospective study was conducted with children who underwent robot-assisted laparoscopic surgery for B/P RMS between July 2018 and March 2020 under the approval of IRB of our center. The patient characteristics, tumor position, perioperative information, short time oncologic survival outcomes, and urinary function were recorded and evaluated.

We performed a retrospective study of 9 infants under 3 months who underwent RALP for severe UPJO between April 2017 and March 2019 in our center. The severe UPJO was defined as infants with severe hydronephrosis (Society of Fetal Urology grades III or IV, anteroposterior diameter >3 cm or split renal function <40% or T 1/2 >20 min) involving bilateral, solitary kidney, or contralateral renal hypoplasia UPJO at the same time.

Materials And Methods: Six children with long ureteral defect who underwent laparoscopic Yang-Monti ureteral reconstruction between January 2013 and March 2016 were reviewed. The diagnosis and outcomes of long ureteral defects were reviewed based on clinical and imaging data.
Introduction: Laparoscopic pyeloplasty has achieved good cosmetic and functional outcomes. Both transumbilical single-site and transumbilical multi-port approaches are currently being used. No comparison of transumbilical single-site laparoscopic pyeloplasty (TSLP) and transumbilical multi-port laparoscopic pyeloplasty (TMLP) has been reported in the literature.

Background: Common causes of complications of laparoscopic pyeloplasty in children include anastomotic stricture, poor drainage due to high ureteropelvic anastomosis, and torsion of ureter. Herewith, we described our modified technique of paraumbilical three-port laparoscopic dismembered pyeloplasty (PTLDP) to minimize these complications.
Patients And Methods: Data from 62 patients (age: 1-180 months, median: 12 months) with ureteropelvic junction obstruction (UPJO) who underwent pyeloplasty using our modified technique of PTLDP between February 2014 and September 2014 at our institution were reviewed.
Although alginate was reported to play an important role as free radical scavengers in vitro and could be used as sources of natural antioxidants, there was no study about the cryoprotective effects of alginate on boar spermatozoa freezing. The objective of this research was to evaluate the effects of different concentrations of alginate added to the freezing extenders on boar spermatozoa motility, plasma membrane integrity, acrosomal integrity, mitochondrial activities, lipid peroxidation and antioxidative enzymes activities (SOD and GSH-Px) after thawing. Alginate was added to the TCG extender to yield six different final concentrations: 0, 0.
