Clinical Trial Summary

The purpose of this clinical trial is to compare new reconstruction and anastomosis in robot-assisted radical laparoscopic resection It will also understand the possibility of exploring new reconstruction in completely solving patients' postoperative urinary incontinence The main questions it aims to answer are: Is there a significant improvement in urinary control in patients with new reconstruction compared with patients with anastomosis? The researchers compared the new reconstruction with anastomosis in robot-assisted laparoscopic radical resection to see if the new reconstruction improved urinary incontinence after operation. Participants will: The intervention group adopted the new reconstruction proposed by our team; End-to-end anastomosis was performed in non-intervention group.


Description:

It is one of the most common malignant tumors in urology, and its incidence rate is the second among male malignant tumors in the world. In recent years, with the economic and social development in China, the incidence rate has increased year by year, which seriously threatens the Radical resection is the current treatment plan. Although radical surgery can prolong the survival time of patients, because of the surgical injury, the incidence of urinary incontinence and sexual function after operation is high, which greatly affects the physiological health, mental health and social function of patients. In order to solve the above problems, Professor Shi Benkang's team of Urology Department of Qilu Hospital of Shandong University improved the existing urinary tract reconstruction after consulting a large number of related literatures and combining with the new findings of our team's previous anatomical work, which needed to be carried out under Da Vinci Xi surgical system. By continuously suturing the fascia on the surface of levator anal muscle and the posterior dorsal median ridge (MDR) and Dirichlet fascia of the lateral tissue, it achieved the purpose of protecting the apical saccular tube bundle (NVB) and maintaining the stability of the length of vascular and nerve lengthening function in the posterior MDR We found that the postoperative urinary incontinence of patients with new reconstruction technique is obviously better than that of anastomosis, which provides a new idea for improving the postoperative urinary incontinence of RARP patients.
