Comparison of Magnetic and Conventional Double-J Stent Following Kidney Transplantation: A Randomized Controlled...

This monocentric, randomized controlled trial aims to compare the outcomes of kidney transplant recipients with magnetic double-J (DJ) stents versus conventional DJ stents. Specifically, we assessed stent-related symptoms, procedural difficulties, pain and duration of removal, and associated costs.

A total of 30 patients were randomly assigned to receive either a magnetic DJ (mDJ) stent or a conventional, standard DJ (sDJ) stent during kidney transplantation using the Lich-Gregoir technique. Quality of life was evaluated with the USSQ 7-10 d postoperation. sDJs stents were removed cystoscopically by a urologist while mDJ stents were removed bedside by a transplant surgeon. The duration of removal and procedure-associated pain were documented. Questionnaires for physicians and patients were used to assess peri-interventional experience and issues. Additionally, costs associated with the removal of both stents were analyzed.

Quality of life showed no differences between the groups. Stent removal was successful in all cases, with no differences in duration of removal (P = 0.24) or major issues. Patients reported comparable pain levels during the removal of mDJs (P = 0.55) and higher satisfaction, although this was not statistically significant (P = 0.27). Cost analysis revealed a reduction of approximately €172 with the use of mDJ.

The use of mDJ stents in kidney transplantation is a safe alternative associated with comparable pain during removal. Additionally, it offers cost savings and reduces the logistical burden for both patients and hospitals.
