Outcomes of Robot-Assisted Laparoscopic Isthmus Division Using Endoscopic Transection Equipment in the Treatment of Symptomatic Horseshoe Kidney

Abstract

Background: The surgical treatment of horseshoe kidney (HSK) remains a huge challenge because of the complex anatomy and abnormal blood vessel distribution. Therefore, this study aimed to evaluate the surgical technique and outcomes of robot-assisted laparoscopic isthmus division using endoscopic transection equipment (endoscopic linear stapler; Ethicon, ECHELON 60 FLEX™) in the treatment of symptomatic HSK and to conduct a literature review. Materials and Methods: Patients with HSK who underwent robot-assisted laparoscopic isthmus division using endoscopic transection equipment from August 2015 to August 2019 at the First Affiliated Hospital of Anhui Medical University in China were recruited. Isthmus division was conducted using an endoscopic linear stapler. Results: All 10 surgeries were performed successfully. Major organs and large blood vessels were effectively protected. Only 1 patient presented with postoperative perinephric effusion. The mean operative time was 179 minutes, and the mean length of the postoperative hospital stay was 6 days. During the 1- to 5-year follow-up, all patients were cured with mitigated symptoms and improved renal function, except for 1 patient with transitional cell carcinoma who died of multiple metastases 18 months postoperatively. Conclusion: Robot-assisted laparoscopic isthmus division using endoscopic transection equipment is a safe and effective method to manage patients with symptomatic HSK and to help them have few complications and quick recovery.
