“…in 2007. Since then, several reports have followed (Table ), with the rate of cases of renal percutaneous cryoablation therapy necessitating hydrodissection described to be 9.9–55% . The distance of the tumor from adjacent organs after hydrodissection was noted to be 16–27 mm .…”

“…With hydrodissection, before cryoablation an 18‐ or 20‐G introducer needle is placed into the retroperitoneal space under imaging guidance, followed by insertion of fluid . CT has been most commonly used for guidance . Fluids used in hydrodissection have been saline, lactated Ringer solution, sterile water and 5% glucose water .…”

“…One major advantage of hydrodissection is the ability to precisely monitor fluid distribution and organ displacement using imaging guidance, such as with ultrasound, CT and magnetic resonance imaging . For cryoablation carried out under CT guidance, the addition of iodized contrast medium to increase visibility of injected fluids was recommended . Patel et al .…”

Renal cryoablation has become accepted as treatment for small renal tumors as an alternative to surgery. However, parallel with the increase in the use of this therapy, there also has been increases in the number of reports of complications related to renal cryoablation. One potential complication is injury to important non-renal structures adjacent to the ablated renal tumor, such as the colon, duodenum, ureter, psoas muscle and so on. To prevent injury of adjacent organs, separating organs from the tumor is desirable. Over the past 15 years, several techniques have been developed to protect against injury of organs adjacent to renal tumors that are targets of cryoablation. The most commonly used technique for this purpose has been hydrodissection. Others include dissection with gas, balloon dissection and probe traction. To avoid injury of a ureter running near the renal tumor, pyeloperfusion is known to be useful. The rate of cases necessitating avoidance of organ injury by using these techniques is relatively high. In some cases, more than two techniques are combined. In the present review, we provided an overview of techniques currently available to protect against organ injuries, and discussed the advantages and disadvantages of each technique.
