Introduction: The purpose of this study was to evaluate the complications of duplicated ureters in renal transplant recipients.
Methods: Between 1983 and 2004, 12 patients (median age 34 years) received renal transplants from donors with duplicated ureters. In four patients the ureter to bladder anastomoses were performed separately according to the method described by MacKinnon, including two cases transplanted with ureteral catheters because of narrow widths. In the following cases of eight duplicated ureters an anastomosis was performed between the distal part of each ureter to form a common ureteral ostium, which was connected to the urinary bladder. A ureteral catheter was used to the splint ureterovesical anastomosis.
Results: No graft loss to ureteral complications was observed. There was no ureteral necrosis in the postoperative period. No clinical symptoms of ureteral junction obstruction were revealed after removing the ureteral catheter. By ultrasound examination four patients showed a slight temporary pyelocaliectasis was observed and four patients developed temporary urinary fistulas.
Conclusion: Our ureterocystoneostomy procedures with duplicated ureters were safe and useful in kidney transplantation.

Objective: To review and compare robot-assisted ipsilateral ureteroureterostomy (RALUU) and laparoscopic ipsilateral uretero-ureterostomy (LUU) in terms of efficacy and outcomes.
Methods: Clinical data of 65 children with complete renal ureteral duplication deformity admitted to the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022 were collected. Among these, 42 patients underwent laparoscopic ureteroureterostomy (LUU), designated as the LUU group, while 23 patients received robot-assisted laparoscopic ureteroureterostomy (RALUU), designated as the RALUU group.

Objective: This study evaluates the efficacy and safety of robot-assisted laparoscopic ipsilateral ureteroureterostomy (RAL-IUU) in treating children with duplex kidney ureteral malformations by detailing our early single-center experience.
Materials And Methods: We conducted a retrospective analysis of clinical data from 14 children with complete duplex kidney ureteral malformations treated with RAL-IUU at our institution from December 2021 to January 2024. Clinical data included patient demographics, surgical details, and postoperative outcomes.

Introduction: A comprehensive understanding of the renal vascular anatomy variations is paramount to a successful kidney transplant. This reduces vascular injury risks and minimizes ischemia duration, optimizing surgical outcomes. The current study aims to assess the accuracy of renal computed tomography angiography (CTA) findings of live renal donors by comparing them with intraoperative findings.

Objective: To explore the therapeutic value of laparoscopic ureteroureterostomy compared to single ureteral bladder reimplantation in the treatment of pediatric complete renal duplication.
Methods: This retrospective study included 80 pediatric patients with complete renal duplication who underwent surgical treatment at the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022. Patients were divided into two groups based on the surgical approach: the laparoscopic ureteroureterostomy group (LUU group, n = 45) and the single ureteral bladder reimplantation group (UR group, n = 35).

Congenital anomalies are rare in veterinary medicine, and their aetiology, development, clinical presentation, and management remain poorly understood. This study documents a rare case of multiple congenital anomalies occurring simultaneously in a single individual. We present a comprehensive analysis of a 4-month-old mixed-breed puppy diagnosed with caudal duplication (monocephalus dipygus), integrating clinical, radiographic, ultrasonographic, cytogenetic findings, and surgical intervention.
