To discuss the clinical efficacy and safety discussion of flank-suspended half lithotomy position percutaneous nephrolithotomy in the treatment of high-risk patients with urinary stones.

From July 2017 to March 2018, 56 cases with high-risk urinary stones in our hospital were selected as the research object. They were divided into flank-suspended half lithotomy position group and prone position group, 28 cases in each group according to the operation position.Basic data were no significant difference in both groups(P>0.05), and two groups were given routine percutaneous nephrolithotomy treatment. The indexes such as surgical curative effect, channels establishing time, operation time, intraoperative blood loss, one-time calculi clearance, moreover the blood pressure, heart rote, respiration, saturation of blood oxygen of the two groups were compared.

Two groups of patients were successfully completed surgery, without death and severe risk events. The channels establishing time, operation time, intraoperative blood loss, one-time calculi clearance, the blood pressure, heart rote, respiration, saturation of blood oxygen of the flank-suspended half lithotomy position group were obviously better than the prone position group, the difference was statistically significant(P<0.05).

The flank-suspended half lithotomy position percutaneous nephrolithotomy in the treatment of high-risk urinary stones has remarkable curative effect, it can shorten operation time, reduce blood loss, has less influence on hemodynamics, it is worth of clinical application.
