Detailed Description
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
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: group (A) included 30 cases in which we used bipolar coagulation for hemostasis group (A) included 30 cases in which we used bipolar coagulation for hemostasis |
Procedure: laparoscopic partial nephrectomy
Operations were done under general anesthesia. Patients were positioned in modified lateral kidney position for trans-peritoneal procedures. Pneumoperitoneum using the Veress needle technique and trocar placement . Dissection to the renal hilum for good and sufficient exposure of the renal vessels. Good exposure of the tumor and marking the excision site with electro cautery. Clamping of renal vessels using laparoscopic Bulldog appliers. Excision of the renal mass using visual assessment to determine the suitable depth of normal parenchyma to be excised in order to achieve a negative surgical margin. Unclamping was done and re-assessment of the hemostasis to secure residual bleeding points. Approximation of the edges of renal parenchyma using suturing in both groups. The specimen was placed in an EndoCatch bag and removed through pfannenstiel incisionsurgical drain was placed in the paracolic gutter
