Purpose:
To determine the number of lymph node of pre-prostatic fat and the incidence of metastatic lymph nodes in the lymph node dissection during robotic assisted radical prostatectomy(RARP)   
Materials and Methods:
During December 2012 to September 2015, pre-prostatic fat was removed in182 patients who underwent RARP. These tissues were sent for pathological analysis to determinate the number of lymph nodes and the count of metastatic lymph nodes. Another 128 patients without pre-prostatic fat removal were collected as control group. Operation features, such as time consumption of operation, estimated blood loss, day of hospitalization, and incidence of complication were compared within these two groups.
Results:
Lymph nodes within pre-prostatic fat were detected in 17/188(9%) patients. Metastatic lymph node was found in 2/188 (1%) among these patients. Patients with metastatic lymph nodes in pre-prostatic fat had no obturator lymph nodes involved. There were no significant differences of operation features between experimental and control group.
Conclusions:
Our analysis demonstrates that pre-prostatic fat contains lymph nodes. The rate of present of lymph node metastases was high. There was no increasing of the risk of surgery for Pre prostatic fat removal. Therefore, It should be routinely removed and received pathological analysis at radical prostatectomy for precise lymph node staging
