Objective: To compare outcomes and postoperative quality of life (QoL) among patients with kidney stone who received mini-percutaneous nephrolithotomy (mPCNL), partial tubeless mPCNL or mPCNL with ureter catheter in a prospective randomized clinical trial. Methods: From May 2017 to December 2017, 60 patients with kidney stone who underwent mPCNL were randomized into 3 groups: Group I (mPCNL), Group II (partial tubeless mPCNL), Group III (mPCNL with ureter catheter). We evaluated perioperative characteristics, stone clearance, analgesic requirements and QoL by using the Wisconsin Stone QOL questionnaire. Results: The age, gender, stone diameter, body mass index, length of operation, drop in hemoglobin and stone-free rates for the 3 groups were similar among these groups. However, the postoperative visual analog scale and the analgesic requirement in Group II were significantly the lowest (p < 0.05). According to Wisconsin Stone QOL questionnaire, compared to Group I, statistical significant difference in the QoL was seen in Group II and III, indicating a meaningful and immediate improvement in the postoperative QoL following mPCNL. Conclusion: Compared with standard and partial tubeless mPCNL, mPCNL with ureter catheter is a safe and useful form of mPCNL, which can offer better QoL and is more cost effective. (C) 2018 S.
