Abstract Objective The aim of this study is to evaluate the impact of ureteric stent diameter on stent‐related symptoms and early urological complications in kidney transplant recipients. Patients and Methods A single‐centre randomised controlled trial that enrolled 70 kidney transplant recipients to receive either a 4.8 Fr or 6 Fr ureteric stent allocated at a 1:1 ratio was conducted. Stent‐related symptoms and patient‐reported outcomes were assessed using the Ureteral Stent Symptom Questionnaire (USSQ) and a visual analogue scale (VAS) for pain. Early postoperative complications—including urinary leakage, ureteric obstruction and urinary tract infection (UTI)—were recorded. Results The 4.8 Fr stents were associated with significantly fewer stent‐related symptoms and lower USSQ scores than 6 Fr stents (47.0 ± 4.5 vs. 53.9 ± 4.2; p < 0.001). Patients who received a 4.8 Fr stent experienced lower pain intensity than those who received a 6 Fr stent (VAS 1.4 ± 0.7 vs. 2.2 ± 0.8; p < 0.001). Rates of urinary leakage, ureteric obstruction and UTI were comparable between the two groups. Conclusion The 4.8 Fr ureteric stents reduce stent‐related symptoms and postoperative pain while demonstrating a similar early safety profile to 6 Fr stents. These findings support the use of smaller‐calibre stents to improve postoperative comfort following kidney transplantation.
