Renal stone, percutaneous nephrolithotomy


Objective:  The aim of this study was to compare the postoperative outcomes of patients receiving standard percutaneous nephrolithotomy (S-PCNL) and
modified mini percutaneous nephrolithotomy (MM-PCNL) in Yala Hospital.

Material and Method:  We collected data from 117 patients who underwent S-PCNL or MM-PCNL from 2013-2018. We compared the data of patient characteristics, laboratory results, and postoperative outcomes, such as operative times, duration of catheter, blood transfusion rate, duration of hospitalization, stone free rate and complication rate between the S-PCNL and MM-PCNL groups.

Results:  There were no significant differences in operative time, blood transfusion rate, stone free rate and complication rate between the 2 groups. However, the duration of catheter and hospitalization in the MM-PCNL group was significantly shorter than in the S-PCNL group.

Conclusion:  Hence, we confirmed that MM-PCNL could be used as an alternative procedure to Mini-PCNL for the management of renal stones in other
tertiary hospitals which already have the equipment for S-PCNL by modifying that equipment, as we have shown.
