Clinical application of rigid ureteroscope combined with holmium laser in diagnosis and treatment of complicated hepatolithiasis guided by three-dimensional visualization technology / 中国医师杂志

ABSTRACT

Objective:To analysis the application value of rigid ureteroscope combined with holmium laser in diagnosis and treatment of complicated hepatolithiasis guided by three-dimensional visualization technology.Methods:50 patients with complex hepatolithiasis treated in Hunan People′s Hospital from October 2016 to March 2019 were selected as the study subjects. They were divided into observation group and control group by simple random method. 20 cases underwent rigid ureteroscope combined with holmium laser under the guidance of three-dimensional visualization technology were taken as observation group, 30 cases underwent rigid ureteroscope combined with holmium laser by traditional imaging diagnosis were taken as control group. The differences between the two groups in operation time, intraoperative bleeding volume, stone residual rate, postoperative hospital stay and postoperative complications were statistically analyzed.Results:The residual rate of calculi in observation group was 10% (2/20), while it was 40% (12/30) in control group; the amount of bleeding during operation in the observation group was (170.9±18.0)ml, and it was (371.6±37.0)ml in the control group; the operation time of observation group was (179.0±14.3)minutes, and it was (340.2±24.3)minutes in the control group; the postoperative hospital stay of observation group was (8.3±1.5)days, and it was (10.1±1.8)days in the control group; postoperative biliary hemorrhage occurred in 1 cases of the observation group, biliary tract leakage occurred in 2 cases, postoperative biliary hemorrhage occurred in 3 cases of the control group, biliary tract leakage occurred in 4 cases.Conclusions:Rigid ureteroscope combined with holmium laser guided by three-dimensional visualization technology can further improve the clinical efficacy in the diagnosis and treatment of complex hepatolithiasis. which is worthy of clinical application.
