Bipolar Coagulation Versus Suture Renorrhaphy in Laparoscopic Partial Nephrectomy

Partial nephrectomy is the standard of care for T1 renal masses (local tumour) it preserves as much normal renal tissue as possible to avoid post-operative acute renal failure, chronic kidney disease and associated metabolic and cardiovascular morbidities . The main challenges that affect partial nephrectomy outcome is the need for renal ischemia to achieve good hemostasis, and the long-term oncological consequences associated with positive surgical margin. Laparoscopic partial nephrectomy has been widely used lately as it is associated with less blood loss, short hospital stay and early recovery in comparison to open partial nephrectomy . Hemostasis of the tumor bed after laparoscopic partial nephrectomy can be achieved by various techniques including Suture renorrhaphy which can be used whatever the bleeding area, the size of bleeding vessel, or the amount of bleeding. However, it consumes more ischemia time, involves functional parenchyma, and requires high laparoscopic skills . There for in our study we tried to find a way to improve the functional and oncological outcome of laparoscopic partial nephrectomy by comparing the bipolar coagulation versus conventional suture renorrhaphy in performing stable hemostasis of tumor bed
