Double J stent is superior to externally draining ureteric stent in enhancing recovery after kidney transplantation - A prospective cohort study

Background: Routine intraoperative ureteric stenting lowers the rate of urological complications after kidney transplantation. However, there is no consensus about the optimal stent design and duration. The aim of this prospective cohort study was to compare the influence of double J (JJ) stents and externally draining percutaneous (PC) stents on the early quality of recovery after living donor kidney transplantation. Materials and methods: A prospective cohort study was performed in two consecutive cohorts of 40 patients who underwent living donor kidney transplantation at the Radboud university medical center between April 2016 and October 2017. The first cohort of 40 patients received a 6-French externally draining PC stent. The second cohort of 40 patients received a 6-French/14 cm JJ stent. We compared the influence of the stent design on the quality of early post-operative recovery (measured by the Quality of Recovery-40 questionnaire) and the length of hospital stay. Results: Patients with a JJ stent scored significantly better on the Quality of Recovery score on the third and fifth postoperative day, when compared to patients with a PC stent. Furthermore, in comparison to patients with a PC stent, patients with a JJ stent were earlier mobilising and independent in daily activities, resulting in a shorter length of hospital stay. The number of postoperative urological complications was comparable between the two groups. Conclusion: The use of JJ stents during living donor kidney transplantations improves the postoperative recovery and shortens the length of hospital stay, when compared to PC stents without compromising the number of postoperative urological complications.
