Brief summary

In this study, we plan to explore the risk factors closely related to the occurrence of urinary leakage after partial nephrectomy for renal hilum tumors through retrospective analysis of multicenter clinical data, thereby providing clinical guidance value for the prevention of postoperative urinary leakage.
