Comparative study on flexible ureteroscopic lithotripsy and percutaneous nephrolithotomy for treating renal pelvis calculus / 重庆医学

ABSTRACT

Objective To investigate the effects of flexible ureteroscopic lithotripsy and percutaneous nephrolithotomy for treating renal pelvis calculus.Methods The clinical diagnosis and treatment data in 65 patients with single renal pelvis calculus treated in department of urology surgery of our hospital from Jan.2013 to Jan.2016.Among them,33 casesas the group A adopted flexible ureteroscopic lithotripsy and 32 cases as the group B adopted percutaneous nephrolithotomy.The operative time,lithotripsy success rate,complications and average hospitalization time were compared between the two groups.Results In the renal pelvis calculus diameter ≥ 2 cm,the operation time and lithotripsy success rate in the group B were significantly better than those in the group A,but the intraoperative blood loss and average hospitalization time in the group A were significantly better than those in the group B,the differences were statistically significant (P＜0.05).In renal pelvis calculus diameter ≤2 cm,the lithotripsy successful rate had no statistically significant difference between the two groups (P＞0.05),but the group A was significantly better than the group B in the operative time,intraoperative blood loss and average hospitalization time (P＜0.05).Conclusion Renal pelvis calculus diameter ＜2 cm is suitable for selecting flexible ureteroscopic lithotripsy,but which ≥2 cm is suitable to select percutaneous nephrolithotomy.
