Minimally Invasive Kidney Transplantation: The First Experience

Minimally invasive procedures in recent years have gained widespread acceptance. Within the field of transplantation, laparoscopic living donor nephrectomy (LLDN), requiring a 6- to 10-cm incision, is now considered the optimal procedure. According to recent MEDLINE searches, no minimally invasive technique has been reported for kidney transplantation. Considering the rapid evolution of minimally invasive surgery during the last decade, there is little reason to believe that kidney transplantation in future will be excluded from this development. A novel minimally invasive technique for kidney transplantation (MIKT) is presented, restricted to a 7- to 9-cm incision and minimal dissection/tissue trauma. The kidney is meticulously prepared on the back table and placed in a fitted lateral, retroperitoneal pouch. All three anastomoses are performed with the kidney in its final “in situ” position, and ureter reimplantation is done by extravesical technique. Twenty-one patients have been transplanted by MIKT and followed in a prospective manner, along with a matched control group subjected to conventional kidney transplantation. Our results indicate that MIKT may be executed safely and quickly. Beneficial effects on postoperative pain/analgesia, recovery, and complications are suggested by this first MIKT experience. The technical solutions of MIKT are per se not unique. However, the incision is minimal and not larger than the one required for LLDN. Minimally invasive surgery seems particularly attractive in the immunosuppressed population, and even more so with the recent introduction of potent antiproliferative drugs.
