Comparative study on curative effect of minimally invasive percutaneous nephrolithotomy and the traditional open operation in treatment of renal calculus

Objective To investigate the curative effect of minimally invasive percutaneous nephrolithotomy and the traditional open operation in treatment of renal calculus.Methods Randomly selected 100 patients of renal calculus and divided into two groups,minimally invasive group used minimally invasive percutaneous nephrolithotomy,the traditional open operation group were treated with traditional open operation.compared two groups with the operation time,bleeding volume during operation,postoperative hospital stay and complications.Results The operation time、 hospital stay、operation bleeding and complications in the minimally invasive group in were obviously fewer than those of the traditional group patients,stone clearance rate improved,complications of operation bleeding,the difference was statistically significant(P0.05).Conclusion In the treatment of renal calculi,minimally invasive percutaneous nephrolithotomy had better prognosis in patients with less time,less bleeding,High stone clearance rate,less complications.
