MINI-PERCUTANEOUS NEPHROLITHOTOMY (MINI-PCNL) VERSUS STANDARD PCNL (S-PCNL) FOR RENAL STONE OF MORE THAN 2CM IN DUHOK GOVERNORATE
Background: This research aimed to make a comparison between the mini-percutaneous nephrolithotomy (Mini-PCNL) versus standard (S-PCNL) techniques for kidney stones of more than 20mm in regards of their rates of success and complications in candidates with urolithiasisin Azadi teaching hospital and Vajeen private hospital in Duhok governorate.
Patients and procedures: This clinical research was performed during April 2018-April 2019. Fifty participants with renal stones larger than 2cm were assigned into two groups regarding their treatment options by PCNL, either Mini-PCNL by using nephroscope 18 Fr through 24 Frsheath, or by the S-PCNL by using 24 Fr nephroscope through 30Fr sheath. The stones were crushed with pneumatic lithotripsy.
Results: Our data have shown that there was no difference in the stone free rates in both groups but statistically significant differences in postoperative haematocrit level, operative time, analgesic requirement, hospital stay, and complication rate among the patients applying Fisher’s exact tests, Chi square or Student-t test as needed. In addition to the logistic regression analysis. No significant differences were seen in patient’s characteristic between the two groups with.
Conclusions: Mini-PCNL has similar efficacy and SFR with lower complication rates in comparison with S-PCNL.
