Abstract:
【Objective】 To explore the safety and efficacy of a novel endoscopic two-wire guided dilation in the creation of channels in percutaneous nephrolithotomy (PCNL). 【Methods】 Clinical records of 180 patients undergoing PCNL during Oct.2020 and Oct.2022 were retrospectively analyzed. The patients were divided into three groups, 60 in AMD group (fascial amplatz dilation), 60 in OSD group (one shot dilation) and 60 in END group (endoscopic dilation). Time to establish channels, operating time, failure of access, stone clearance rate, drop in hemoglobin, embolization rate, fever rate, blood transfusion rate and postoperative hospitalization were compared among the three groups. 【Results】 There were no significant differences in the general data among the three groups (P>0.05). Compared with AMD and OSD groups, END group needed significantly reduced time to establish the first channel [(5.6±0.8) min vs. (4.9±1.4) min vs. (4.2±0.5) min, (P<0.05)] . Compared with OSD group, END and AMD groups had significantly more hemoglobin drop [(14.0±17.6) g/L vs. (19.4±12.6) g/L vs. (10.2±6.8) g/L, (P<0.05)] . There were no significant differences in terms of failure of establishing channels, operating time, stone clearance rate, embolization rate, fever rate, blood transfusion rate and postoperative hospitality. Four patients needed selective renal artery embolization (1 case in AMD group and 3 in OSD group). No serious complications such as organ injuries, septic shock or death occurred. 【Conclusion】 Endoscopic two-wire guided dilation is simple, with few complications and good application value.
