Right Laparoscopic Radical Nephrectomy Ralph V. Clayman, MD Professor of Urology University of California, Irvine
Patient Selection • Indications • Renal mass (not amenable to partial nephrectomy) • Contraindications • Vena caval thrombus • Peritonitis • Uncorrected coagulopathy • Multiple prior abdominal surgeries (relative) • Significant medical comorbidities (relative)
Equipment Required • Veress needle (14G Surgineedle) [Autosuture] • Knife with #15 blade • Kelly and Allis clamps • Trocars: 12 mm (3), 5 mm (2) • Laparoscopic camera with 30 Lens (have 5 mm 30 available) • Argon Beam Coagulator • Hook Electrocautery with Active Electrode Monitoring [Encision] • LigaSure (5 mm) [Valleylab] • Harmonic Shears-5 mm curved [Ethicon] • Kuttner Dissectors: 5 mm Endo Peanut [Autosuture] 10 mm Endoscopic blunt cherry dissector [Ethicon] • 5 mm atraumatic bowel forceps [Karl Storz] • Laparoscopic Right Angle Clamp (5 mm and 10 mm) • EndoGIA stapler (45 mm vascular load, articulating handle) [Ethicon] • Nezhat-Dorsey suction-irrigator [Davol] • Grasping forceps with teeth (locking handle) (3) • Endoholder (self-retaining retractor) [Codman] • Floseal hemostatic collagen matrix [Baxter] • Oxidized cellulose (Surgicel) • Lap Sac (8”x10”) entrapment sac with two tine introducer (Cook) • Curved ring forceps for morcellation • Suture: 0-Vicryl, 4-0 monocryl
Patient Positioning • Full flank, supported by hip grips and gel pads • Lower (left) leg bent, 3 pillows supporting upper (right) leg • Table flexed 15 • Axillary roll • OR table covered with gel pad (never bean bag) • Right arm draped over chest, supported by 2 pillows • Table airplaned 10 to the right • Arms, hips, and lower leg secured by tape over eggcrate padding • Kidney rest raised only during insufflation, then lowered
Port Placement • Veress needle placed 2 finger breadths medial and superior to iliac crest, followed by 12 mm port • Primary 12 mm camera port: umbilicus in thin patient, >6 cm lateral and slightly superior to umbilicus for obese patient • 12 mm port 1 finger breadth below costal margin, midclavicular line • Liver retraction (5 mm), midline, subxiphoid • Accessory (5 mm) retraction/working port: anterior axillary line, subcostal
Port Placement 5 mm accessory port Primary (12 mm) working ports Liver retraction (5 mm)
Steps of the procedure 1. Placing the ports 2. Mobilizing the colon 3. Mobilizing the liver and upper pole 4. Kocherizing the duodenum 5. Freeing the lower pole 6. Dissecting the hilum 7. Dividing the ureter • Placing the specimen in a Lap Sac for morcellation
Placing the specimen in a Lap Sac for morcellation
Technical points: Tips • Make sure to take down the triangular and posterior coronary hepatic ligaments in order to mobilize the liver cranially and medially and expose the vena cava. • The argon beam coagulator can stop small bleeders. • Make liberal use of Kuttners for dissection and retraction. They are especially useful around the hilum. • There is no “camera” port. The camera and instruments should be freely shifted between the 12 mm ports as necessary wherever exposure is the best. • 5 mm ports are “free”. If you are struggling, do not hesitate to place one to provide a better working angle.
Technical points: Caveats • When dissecting the midportion of the kidney medially, the first structure encountered will ALWAYS be the duodenum, not the vena cava. Temporarily lowering the pneumoperitoneum to 5 mm will help it to fill out. • The hook can be used to dissect on the anterior surface of the vena cava. When approaching the lower pole, beware the insertion of the gonadal vein on the anterolateral surface of the IVC • Take extreme precaution when morcellating to avoid tumor spillage: triple drapes, change of gowns/gloves, instillation of betadine in the wound.
