  1. Note: The classification of lymph node numbers dissected is as follows: S0 denotes zero lymph node, S1 represents a range of 1 to 10 lymph nodes, S2 indicates a range of 11 to 20 lymph nodes, and S3 signifies the presence of more than 20 lymph nodes. The classification of positive lymph nodes number dissected is as follows: P0 denotes zero positive lymph node, P1 represents one positive lymph node, P2 indicates a range of 2 to 5 positive lymph nodes, and P3 signifies the presence of more than 5 positive lymph nodes. The univariate analysis encompassed variables that exhibited notable disparities between groups, including BMI, extent of pelvic lymph node dissection, number of lymph node dissection and positive lymph nodes, as well as factors that potentially influence lymphatic leakage, such as T stage, urinairy diversion method, surgical procedure and Surgeon’s experience. Multivariate analysis showed that the number of lymph node dissection was independent risk factors for lymphatic leakage
