Laparoscopic Cryoablation

Laparoscopic Kidney Cryoablation

Laparoscopic cryoablation of kidney tumors is based upon similar principles of laparoscopic partial nephrectomy. This relatively new technique greatly simplifies the challenge of treating only a select kidney lesion without compromising the remainder of the kidney. A laparoscopic dissection aids in reliably placing small probes through the skin directly into the target lesion. Subsequently, an ice ball is generated that has been shown to effectively kill tumor cells. An advantage conferred by this technique over laparoscopic partial nephrectomy is that it avoids complex maneuvers such as clamping of the main blood vessels to the kidney and laparoscopic suturing of the kidney after the tumor has been removed. The main disadvantage is that in preliminary followup, there has been a higher incidence of cancer recurrence. Therefore, this technique is reserved for elderly individuals who are poor surgical candidates, yet have a small, peripheral kidney tumor that requires treatment.
