Abstract:
【Objective】 To compare the clinical safety and effectiveness of super-mini-percutaneous nephroscope (SMP) combined with flexible ureteroscopic lithotripsy (FURL) in oblique supine lithotomy position and FURL alone in the treatment of 2.0-3.0 cm renal calculi. 【Methods】 Clinical data of 55 patients treated during Jan.2018 and May 2021 were retrospectively analyzed, including 47 cases complicated renal calculi, and 14 cases of lower calyceal calculi with infundibulopelvic angle ≤30°. SMP combined with FURL was performed in 23 cases (combined group), and FURL alone was performed in 32 cases (FURL group). The operation time, hemoglobin reduction, postoperative hospital stay, hospitalization expenses, stone-clearance rate and complications were compared. 【Results】 All operations were successful. Compared with the FRUL group, the combined group had significantly more hemoglobin reduction [(16.30±10.17) g/L vs. (6.94±6.61) g/L], longer postoperative hospital stay [(5.35±1.61) d vs. (3.19±1.26) d], and higher hospitalization expenses [(22 481±2 234) yuan vs. (18 209±2 584) yuan] (P<0.05). However, there was no significant difference in operation time [(79.57±8.52) min vs. (79.22±3.83 min),P>0.05]. One month after surgery, CT results showed that the combined group had higher stone-clearance rate (91.30% vs. 65.63%, P=0.027). There was no difference in the complication rate (21.74% vs. 21.88%, P>0.05). One case (4.35%) in the combined group and 5 cases (15.63%) in the FURL group received retreatment (P>0.05). 【Conclusion】 SMP combined with FURL in oblique supine lithotomy position is safe and effective in the treatment of 2.0-3.0 cm renal calculi, with high stone-clearance rate and low complication rate.
