9. Marking the tumor margins

[vc_row][vc_column][vc_column_text]Once the healthy parenchyma has been exposed around the tumor we proceed to mark the margins for excision. Partial nephrectomy should be oncologically safe. This means that the tumor comes out surrounded by a margin of healthy tissue. Traditionally this margin was 5 mm, although different studies have shown that it may be smaller, minimal, …

7. Upper pole and lateral dissection

[vc_row][vc_column][vc_column_text]UPPER POLE DISSECTION Upper pole dissection is an important phase in most partial nephrectomies. In all cases of LPN we perform dissection of the upper pole, to a greater or lesser extent, because it is part of the ascending dissection to release the spleen. I is also important because it contributes to the mobilization of …

6. Renal pedicle dissection

[vc_row][vc_column][vc_column_text]The OBJECTIVES of the left renal pedicle dissection include: Identification and dissection of the renal vein and its branches: gonadal, lumbar and adrenal veins Identification of the renal artery behind the renal vein, near its exit from the aorta To achieve enough dissection of the vessels to have vascular control and be able to perform …

5. Access to the retroperitoneum: peritoneal opening and colon mobilization

[vc_row][vc_column][vc_column_text]The objectives of this phase are: To open the parietal peritoneum, following the line of Toldt, from the iliac fossa up above the spleen To mobilize the descending colon and its mesentery following the avascular plane To identify retroperitoneal references:  gonadal vein, ureter and psoas muscle. Errors we should avoid include: To open through the …

3. Trocar placement

[vc_row][vc_column width=”2/3″][vc_column_text]For left partial nephrectomy we generally use 4 trocars on a diamond shape (Figure  3.1): Pararectal Hasson´s trocar Left iliac fossa 12 mm trocar.

2. Laparoscopic approach and pneumoperitoneal

[vc_row][vc_column width=”2/3″][vc_column_text]Access is performed with a left pararectal minilaparotomy and placement of a Hasson´s trocar at the upper umbilical line, or slightly higher. Veress needle is another acceptable option.   Hasson mini laparotomy and trocar insertion technique: – A 2.0-3 cm incision is performed and deepen to the anterior abdominal fascia. Two reference stitches are …
