Effect of single-channel minimally invasive percutaneous nephrolithotomy and multi-channel minimally invasive percutaneous nephrolithotomy on patients with upper urinary calculi

Abstract

Objective To investigate the effect of single-channel minimally invasive percutaneous nephrolithotomy (MPCNL) and multi-channel MPCNL on patients with upper urinary calculi. Methods A retrospective study was performed on 230 cases of patients with urinary stones who were admitted from June 2015 to September 2019, 125 males and 105 famales, with the age of (41.20±10.32)years old, ranging from 20 to 71 years old.The patients were divided into the single-channel group (n=112) and the multi-channel group (n=118) according to the operation method.with the age of (41.20±10.32) years old, ranging from 20 to 71 years old.The therapeutic effect, perioperative indexes, renal function and complications of the two groups were observed and compared. Results There was no significant difference between the two groups (P>0.05). The operation time and postoperative hospitalization time of the patients in the multichannel Group [(84.25±11.26) min, (13.68±2.27) d]were shorter than those in the single channel group [(101.35±12.34) min, (16.44±3.21) d], and the difference was statistically significant (P 0.05). The operation time and postoperative hospitalization time of the patients in the multichannel Group [(84.25 ± 11.26) min, (13.68 ± 2.27) d]were shorter than those in the single channel group [(101.35 ± 12.34) min, (16.44 ± 3.21) d], and the difference was statistically significant (P 0.05). There was no significant difference in the indexes between the two groups before surgery (P>0.05). Conclusion Single channel MPCNL on the clear majority of urinary stones has good treatment effect, compared with single channel MPCNL, multi-channel MPCNL remove complexity, multiple calculus in the application effect is good, but the multi-channel MPCNL technical requirements of the patient′s body and the physician is higher, and the postoperative complications, more reasonable suggestions according to the specific patient clinical channel is established. Key words: Single-channel minimally-invasive percutaneous nephrolithotomy; Multi-channel minimally-invasive percutaneous nephrolithotomy; Upper urinary tract calculi; Renal function
