MP20-07 A NOVEL EQUIPMENT FOR THE TRAINING OF URETHRAL ANASTOMOSIS PROCEDURE: THE RESULTS OF THE PRELIMINARY STUDY

INTRODUCTION AND OBJECTIVES: The urethroplasty, especially the posterior urethral anastomosis, is always a big challenge to the urologists. We present a completely novel equipment, which can help the urologist to practice the urethral anastomosis procedure. To our knowledge, this is the first equipment for the training of urethral anastomosis procedure in the world. METHODS: The equipment was composed of lithotomy low body part,core urethral part,rectum part and bladder part. The core urethral part was designed as the real bulbar or membranous part stricture. The length of stricture is designed from 0.5 cm to 1.5 cm. The core urethral part can be replaced according to the training request. Three resident doctors practiced the bulbar urethral anastomosis in three patients after watching the standard video of bulbar urethral anastomosis five times, which was set as the control group. Another three resident doctors practiced the bulbar urethral anastomosis in three patients after watching the standard video and practice the training equipment three times, which was set as the training group. The operative duration, the estimated blood loss and surgical outcome in each patient was recorded. RESULTS: In two groups, no statistical difference of stricture length and location was noticed in all patients. The operative duration was shorter in the training group than that in the control group (131.00±8.54 min vs 167.33±13.65 min, P<0.05). It seems that the estimated blood loss was more in control group than that in the training group (81.32±9.01 ml vs 63.00±11.35 ml). However, the significant difference was not noticed. No severe complication, such as rectum injury, was noticed. One stricture recurrence was recorded during the following up in the control group, while no recurrence was recorded in the training group. CONCLUSIONS: Our equipment shows the effectiveness for improving the learning curve of the urethral anastomosis procedure. It can be used for training the urologist before real clinic practice.
