Outcomes of robot-assisted transperitoneal pyeloplasty: Case series
Keywords:Robotic Surgery, Ureteropelvic obstruction, Pyeloplasty
Aim: Ureteral pelvic junction (UPJ) obstruction, which restricts the passage of urine from the pelvis to the ureter may cause progressive destruction of the kidney if left untreated. Causes of UPJ obstruction include various intrinsic and extrinsic factors. Symptomatic UPJ obstruction should be treated without delay. We herein aimed to present the results of robot-assisted pyeloplasty (RAP) that we performed in our clinic.
Methods: Data of 15 patients who underwent RAP between January 2017 and 2019 in our clinic were examined. The diagnosis of ureteropelvic junction obstruction (UPJO) was based on intravenous pyelography (IVP), and diuresis renography (DTPA) was performed during follow-up. Dismembered pyeloplasty was performed on all patients with the DaVinci XI 4-arm robotic system. The results were retrospectively evaluated.
Results: The mean age of all patients was 41.3 (8.2) years. There were 7 males and 8 females. None of the cases had previously undergone pyeloplasty. While 6 of the patients had intrinsic obstruction, 9 had extrinsic obstruction associated with aberrant vascular compression. The mean operation time and duration of anastomosis were 155.3 (29.8) and 33.4 (8.1) minutes, respectively. The mean amount of intraoperative bleeding was 48 (10.2) ml. The mean hospital stay was found as 3.6 (1.1) days. There was no conversion to open surgery in any of the patients. None of the patients had intraoperative or postoperative complications. The mean follow-up time was 12.7 (5.4) months. Postoperative IVP and DTPA of all the patients were found to have improved.
Conclusion: RAP is a minimally invasive method with successful surgical and functional outcomes in the treatment of UPJO.
