Objective: To evaluate the outcome of ureteropyelostomy using the native ureter for the management of ureteric obstruction or symptomatic reflux after renal transplantation.
Materials And Methods: This is a single-center retrospective review of consecutive patients who underwent ureteropyelostomy after renal transplantation between the years 2000 and 2009. Ureteropyelostomy was performed using the ipsilateral native ureter. The native kidney was not removed. Patients' baseline characteristics, preceding interventions, and postprocedural outcomes were analyzed.
Results: Ten patients underwent ureteropyelostomy after renal transplantation. All had initial Lich Gregoir ureterovesical anastomosis. Reasons for the reconstructive surgery were transplant ureteric stenosis in 8 patients or vesicoureteric reflux causing recurrent graft pyelonephritis in 2 patients. Median follow-up was 53 months (range 24-76). Postoperative complications included 3 patients who had transient anastomotic obstruction after removal of the double pigtail stent. They were managed with short-term ureteric restenting or nephrostomy tube insertion. In addition, 2 patients required delayed ipsilateral native nephrectomy because of infection. At last follow-up, all grafts remained unobstructed and free of infections.
Conclusion: Ureteropyelostomy using the native ureter for the management of transplant ureteric obstruction or symptomatic reflux is safe and provides good long-term preservation of graft function in selected patients.

Purpose: To evaluate the feasibility of robot-assisted ureteral reconstruction as a minimally invasive alternative to open surgery for managing ureteric complications in transplanted kidneys.
Materials And Methods: From January 2020 to December 2023, robot-assisted ureteral reconstruction was performed on fifteen kidney transplant patients with vesicoureteral reflux (VUR) or ureteral stricture who had previously failed endoscopic treatments.
Results: Twelve females and three males, with a mean age of 48.

A 55-year-old-male with a chronic left uretero-pelvic junction (UPJ) obstruction managed with intermittent stent exchanges presented with low midline back pain. CT Abdomen/Pelvis revealed spondylodiscitis at L4-L5, further demonstrated on MRI Lumbar spine. Imaging also revealed the left nephro-ureteral stent was mispositioned, with some mild wall thickening of the left ureter.

Background: Approximately 5% to 10% of patients who undergo kidney transplantation develop ureteral stricture, which can be treated endoscopically or by open surgery, which is more effective but complications are common and potentially severe. Robotic surgery has begun to emerge as an alternative in reconstructive procedures. However, few studies have evaluated the role of robotic surgery in this clinical setting.

Introduction: Treatment of de novo vesicoureteral reflux (VUR) into the transplanted kidney constitutes a clinical challenge. Herein, we present our data on patients who underwent endoscopic subureteric injection for the treatment of VUR following renal transplantation (RT) in our center.
Methods: The patients who underwent endoscopic subureteric injection for VUR into the transplanted kidney after RT in our department between 2008 and 2023 were reviewed retrospectively.

Introduction And Importance: Ureteric stump syndrome [USS] is a series of febrile recurrent lower abdominal pain, urinary tract infections, and hematuria that sometimes present with empyema as a rare complication. The ureteric stump is left after ureteric re-implantation due to an impacted stone at the Vesical-ureteric junction [VUJ], or after nephrectomy of a non-functional kidney due to a distal stone; the ureteral stump forms a source of infection to the urinary bladder, in addition to long-term obstructive stones left at the ureteric stamp. This usually cause chronic irritation of the mucosa and potentially change to metaplasia, dysplasia and malignancy.
