Application of Transvaginal Natural Orifice Specimen Extraction Surgery in Urological Surgery

Background: To summarize and analyze the application of transvaginal natural orifice specimen extraction surgery (TV-NOSES) in the operation of renal carcinoma, upper tract urothelial carcinoma, and bladder cancer.Methods: Fifty-seven female patients who underwent 3D laparoscopic radical surgery for urinary tumors and TV-NOSES were analyzed retrospectively. The basic clinical data, perioperative-related data, postoperative complications, and related indexes of postoperative functional evaluation were analyzed and evaluated.Results: All 57 operations were successfully performed according to the original plan. One patient developed mild vaginal infection after operation, which was cured after symptomatic treatment. The visual analog scale scores at 24 and 48 hours after operation were 2.5 (1-4) and 1.1 (0-2), respectively. Patient scar assessment questionnaire scores at 3 months after operation were 37.1 (32-48). Pelvic floor distress inventory-short form 20 scores at preoperative and postoperative 3 months were 5.9 (3-9) and 6.3 (3-9), respectively, and the difference was not statistically significant (P = .48). There was no significant difference in female sexual function index scores between preoperative and postoperative 3 months (P = .82).Conclusions: TV-NOSES in urological surgery is feasible and practical. In addition, this technique further reduces wound pain and wound-related complications without affecting postoperative sexual function and pelvic floor function. The successful development of this technique has laid a solid foundation for further clinical application and promotion. Clinical Trial Registration number: 22/141-3342.
