简要总结

Total tubeless Percutaneous nephrolithotomy (PCNL) is a modified surgical method of PCNL surgery, that is, there is no indwelling nephrostomy tube and double-J tube during PCNL surgery. Compared with traditional PCNL surgery, it has the advantages of reducing pain, shortening operation time and reducing operation cost. Since this procedure was first performed in 2004, several randomized clinical studies have verified the safety and efficacy of total tubeless PCNL. Conventional total tubeless PCNL surgery requires the patient to first undergo retrograde transurethral ureteroscopic insertion of the ureteral catheter in the lithotomy position, and then change the patient to the prone position. However, a large number of literature reports and the surgical experience of PCNL in the past 20 years tell the investigators that the reverse insertion of ureteral catheter can cause many recent surgical complications.The study planned to perform the operation in the prone position without reverse insertion of a ureteral catheter in the total tubular PCNL surgery.

详细描述

The purpose of this single-center, single-blind, randomized trial was to investigate whether without retrograde insertion of a ureteral catheter is appropriate for total tubeless percutaneous nephrolithotomy. It is planned to start in October 2022 and is expected to end in October 2024. Based on inclusion and exclusion criteria, 100 subjects were expected to be recruited. In a parallel group design, subjects were randomly assigned to two groups: the experimental group received total tubeless PCNL without reverse insertion of a ureteral catheter , and the control group received conventional total tubeless PCNL. The primary end point of the study was the incidence of postoperative complications according to the modified Clavien-Dindo complication grading system. Secondary end points included Stone-free rate, operation time, length of hospital stay, and medical costs. Measurement data were expressed as mean ± standard deviation (X ± S), and Student's t-test was used for intergroup comparisons. The counting data were expressed as frequency and percentage, and the chi-squared or Fisher's exact probability test were used for intergroup comparisons. The rank-sum test was used for grade data. P<0.05 was considered statistically significant.
