UROLOGIC OPERATION 15 renal transplantation

Renal Transplantation

Objective

In case of renal failure:

•   Kidney from live donar

•   Or kidney from cadaver is transplanted to restore renal function.

Position

Supine.

Anesthesia

General.

Procedure

   1.  In live donor a nephrectomy is carried out as described care is mobilizing renal artery and vein so as not to injure them.

   2.  Ureter is similarly mobilized with perureteric tissue. Kidney perfused with cold irrigating fluid.

   3.  The iliac fossa of patient (RP) is used.

   4.  Oblique muscle cutting used for access.

   5.  Peritoneum pushed medially.

   6.  Internal iliac artery mobilized branches ligated.

   7.  External iliac vein mobilized.

   8.  Donor kidney renal vein anastomosed to external iliac vein.

   9.  End of internal iliac artery anastomosed to donor kidney renal artery.

10.  Ureter is implanted to bladder.

11.  Wound closed after placing kidney iliac fossa.

Instruments

•   General set

•   Laparotomy set

•   Deep set

•   Vascular clamps (Potts, De Bakey or Satinsky), 2

•   Large bulldog clamps (Potts), 4     (Fig. 8.126)

•   Small bulldong clamps (Potts), 4

•   Heparinized saline, and syringes with cannulae

•   Suction tubing, nozzles and tube anchoring forceps

•   Diathermy leads, electrodes and lead anchoring forceps

•   Tantalum marker clips and insertion forceps

•   Laparotomy ligatures and sutures

•   1 and 0.75 (5/0 and 6/0) Synthetic nonabsorbable or silk on small fine curved arterial needles for anastomosis.

UROLAGIC OPERATION 14 nephtrctomy

Nephrectomy

Objective

In case of tumor or other disease:

•   removal of a kidney.

Position

Lateral.

Anesthesia

General.

Procedure

   1.  For benign disease a flank incision is made (with or without rib resection).

   2.  The kidney and ureter are mobilized.

   3.  The ureter is divided and the distal end ligated.

   4.  Vascular pedicle (artery and vein) is ligated.

   5.  For malignant disease a radical nephrectomy is performed.

   6.  A transperitoneal or anterior retroperitoneal incision is used.

   7.  For large upper-pole lesions, a transthoracic approach may be employed.

   8.  On the right side, the duodenum is protected with mois­tened laparotomy pads.

   9.  The vascular pedicle is transected and lymph node bearing tissue excised.

10.  The ureter is divided, and the kidney and surrounding fat, adrenal gland, and fascia are removed en bloc.

11.  If tumor is present in the renal vein, the vena cava is mobilized and the tumor embolus removed.

12.  The distal ureter is dissected free of surrounding tissues and a small cuff of bladder is excised with the intramural portion of the ureter.

13.  The bladder incision is repaired.

14.  A suprapubic cystostomy catheter may be placed and the distal ureter and bladder cuff are delivered into the flank.

15.  The flank incision may be closed with or without drainage.

16.  For trauma and some presentations of calculus disease involving only a portion of the kidney, a partial nephrec­tomy may be performed.

Instruments

•   General set

•   Deep instrument set

•   Kidney set

•   Thoracotomy tray, vascular procedures tray, and laparotomy procedures set (available)

•   Hemoclip appliers (assorted sizes and lengths)
