Brief summary

Double J ureteral stents (DJ) are widely used in urological practice and commonly inserted after most of ureteroscopies. Stent-related symptoms (SRS) represent a major issue. Many research lines have been explored with the aim of decreasing SRS: Vogt et al. projected a self-made pigtail suture stent (PSS) replacing the distal pigtail with a 0.3 Fr suture reaching the bladder, showing decreased SRS and good tolerance. To date, these promising results hasn't been confirmed by a prospective randomized controlled trial (RCT) involving a marketed PSS. Thus, we designed a prospective single-blind RCT to compare SRS caused by marketed PSS and conventional DJ after uncomplicated URS for stone treatment.
