Introduction: To prospectively study the impact of different drainage methods after FURS on treatment outcomes and health related quality of life (HRQoL) using validated questionnaire.
Methods: A prospective study on adult patients who underwent FURS for renal stones was carried out. Drainage at the end of the procedure was done either by ureteral catheter or double J (DJ) stent according to surgeon decision. We compared the perioperative characteristics, surgical outcomes, and HRQoL using Short Form 36-Item Survey (SF-36) questionnaire among the two groups.
Results: Between January 2020 and July 2021, 340 FURS procedures were performed. Ureteral catheter and indwelling DJ stent were utilized as the drainage method at the end of the procedures in 162 and 178 patients, respectively. There were no significant differences in patients' demographics such as age, gender, body mass index, stone burden, and kidney criteria. Operative time, perioperative complications, post-operative pain and stone free rate were comparable did not show any significant difference between the two groups (all less than <0.05). Furthermore, unplanned visits and hospital readmission did not differ significantly between the two groups (P=0.09). Only 303 patients who showed favorable stone free status at POD1 CT assessment were included in the final analysis of HRQoL. Preoperatively, both groups were comparable in all domains of SF-36 survey with improvement of all domains of SF-36 survey post-operatively. On multivariate analysis, ureteral catheter group showed significant improvement as regard to general health impression and social health interference subdomains when compared to the DJ group (p=0.02).
Conclusions: Our study suggested that the drainage types after FURS using a DJ stent or ureteral catheter were equally safe and efficacious, but patients who received a ureteral catheter had better HRQoL.
