Abstrakt: Introduction: The true benefits of perioperative JJ stent placement are being widely studied due to its known side effects. However, no consensus has been reached in the literature regarding the best type of stent. This prospective, randomized, single-blinded study therefore aimed to compare the symptomatology associated with two JJ stent designs: smooth-walled and grooved.
Materials and Methods: The study prospectively recruited 42 patients who underwent JJ stent placement between July 2019 and August 2020. The patients were randomly divided into two groups according to the JJ stent design used: the smooth-walled stent (control) and grooved stent (intervention) groups. After surgery, all patients completed the Portuguese-validated Ureteral Stent Symptom Questionnaire at three timepoints (days 7 and 30 post-surgical procedure, and day 30 post-stent removal).
Results: No significant differences in gender, age, median body mass index, laterality, type of surgical procedure (flexible, semi-rigid or mixed ureteroscopy) were found. Smooth-walled JJ stents were associated with a higher incidence of flank pain (52.38% vs. 10%, P = .006) and suprapubic pain (57.14% vs. 30%, P = .04) on the 7th post-procedure day. Linear mixed regression showed significantly lower flank (P < .001) and suprapubic pain (P < .01), and significantly better sexual performance in the intervention group (P = .03).
Conclusions: Ureteral stent with a grooved format are associated with a lower incidence of flank and suprapubic pain and had less impact on the sexual performance of patients.
