Introduction & Objective :

Current guidelines may recommend either extracorporeal shock wave lithotripsy (SWL), flexible ureterorenoscopy (FURS) or percutaneous nephrolithotomy (PCNL) for the treatment of the same sized kidney stones. All three treatment modalities have their pros and cons. In this study we aimed to report the patient reported outcomes (PROs) of SWL, FURS and PCNL using the validated Wisconsin Stone Quality of Life (WISQOL) Questionnaire.


Methods :

A total of 45 patients undergoing SWL (Group 1; n=15), FURS (Group 2; n=15) and PCNL (Group 3; n=15) were included in the study. The patients were selected randomly from a cohort of SWL, FURS and PCNL pool, and they filled out the WISQOL questionnaire before and 4 weeks after the treatment.


Results :

Pre- and post-treatment WISQOL questionnaire scores were 66.6±20.1 & 111.4±15; 47.5±12.5 and 125.9±5.5; and 60.6±20 and 117.5±13 for Group 1, 2 and 3, respectively (Table). No statistical significance was observed among Group 1 & 3 before the treatment; but significant difference was noted between Group 1 & 2 (p = .005) and between Group 2 & 3 before the treatment (p = .001). Similarly, there was no statistical significance between Group 1 and 3 following the treatment. Group 2 patients scored higher compared to Group 1 (p = .004) and 3 (p = .016) post-treatment. The WISQOL questionnaire scores increased significantly in each group following the procedures (p


Conclusions : The quality of life increased significantly following intervention regardless of the treatment modality. WISQOL scores were lower in pre-treatment FURS compared to pre-treatment SWL and PCNL; whereas post-treatment WISQOL scores increased significantly in FURS compared to SWL and PCNL, designating greater increase in QOL after FURS in this cohort of patients.
