Abstract: Objective To investigate the effect of laparoscopic anterior urethral wall reconstruction and "Sandwich" reconstruction on early urinary control after radical prostatectomy. Methods A total of 99 patients with prostate cancer were enrolled from February 2014 to December 2019. Totally 56 patients were treated with "Sandwich" reconstruction, and 43 patients were treated with laparoscopic anterior urethral wall reconstruction. It was compared between the two groups with the age, body mass index, prostate volume, preoperative prostate specific antigen (PSA), clinical stage, operation time, pathological stage, Gleason score, lymph node positive rate, postoperative incisal margin positive rate and peripheral urinary control recovery. Results There was no significant difference in age, body mass index, prostate volume, PSA, clinical stage, operation time, pathological stage, Gleason score, lymph node positive rate, and postoperative incisors positive rate (P>0.05). At the 12th week after pulling out the urethral catheter, it was observed that the laparoscopic anterior urethral wall reconstruction was superior to the "Sandwich" reconstruction, but without statistically significance (P=0.058). Conclusion It is safe and easy to use the anterior urethral wall reconstruction in laparoscopic radical prostatectomy, which is superior to the"Sandwich" reconstruction.
