A Novel Neobladder-Urethral Drag-And-Bond Anastomosis Technique During Laparoscopic Radical Cystectomy For Ileal Orthotopic Neobladder: Surgical Technique And Initial Research

Purpose: To explore the application of the neobladder-urethral drag-and-bond anastomosis technique in laparoscopic radical cystectomy (LRC) with ileal orthotopic neobladder (IONB) reconstruction.Patients and Methods: This is a retrospective cohort study on a procedure performed by a single surgeon. From January 2014 to December 2018, we identified 43 male bladder cancer patients who received LRC with IONB reconstruction. These patients were divided into two groups, with 22 patients undergoing neobladder-urethral drag-and-bond anastomosis (NUDA) and 21 patients undergoing neobladder-urethral anastomosis under laparoscopy (NUAL). Anastomosis time, catheter removal time, postvoid residual (PVR), maximum urinary flow rate (Q-max), urine leakage and anastomotic stenosis were used to evaluate the simplicity and surgical effect of the two groups.Results: Both groups demonstrated similar tumor characteristics. A significant difference in neobladder-urethral anastomosis time was found between the NUDA group and the NUAL group (14.6 +/- 0.4 vs 70 +/- 2.5 min, P<0.0001), and there was no significant difference in other characteristics.Conclusion: The neobladder-urethral drag-and-bond anastomosis technique in LRC and IONB reconstruction, with its shorter learning curve, was easier and more convenient than neobladder-urethral anastomosis under laparoscopy.
