Résumé
Objective]To compare the efficacy and safety of retroperitoneal laparoscopic intrasinusal pyelolithotomy (RLIP) and percutaneous nephrolithotomy(PCNL)in the treatment of solitary renal pelvic stone.[Methods]From March 2012 to September 2016,101 patients with solitary renal pelvic stone,divided into RLIP group(n=46)and PCNL group(n=55),were retrospectively analyzed to compare the difference between the two groups in clinical curative effect.[Results]There was no difference between the two groups regarding age,sex,stone side and stone size. Although the operative time was significantly longer,the stone-free rate in the RLIP group was significantly higher than that in the PCNL(P 38.5℃)and the decrease values of hemoglobin and glomerular filtration rate.[Conclusion]Compared to PCNL,RLIP was more efficient and slight safer in the management of solitary renal pelvic stone ,and had a certain value for generalization in clinic.
