“…In our follow up protocol including 3 rd and 6 th month controls, it was seen that no tumor (0%) reccurrences occurred, and this result was also in correlation with the literature (Gervais et al, 2005;Park et al, 2006;Zagoria et al, 2007;Ferakis et al, 2010;del Cura et al, 2010;Kim 2012). Although RFA is a less invasive treatment than surgical treatment options, various complications, such as pain, bleeding, hematuria, infection, urinary fistula, damage of adjacent structures can be occurred in RFA (Aron and Gill, 2005;Kwan and Matsumoto, 2007;Park et al, 2009;Ji et al, 2011;Atwell et al, 2012). In our study, no RFA related complications was detemined in the application and follow up period.…”

“…We reported our intermediate results of LRFA on 106 patients with renal tumors in 2011. Fourteen tumors larger than 4 cm were also included in that cohort, and only one incomplete ablation and 2 major complications occurred in that subgroup [10]. In this regard, to adequately evaluate the efficacy of RFA in the management of SRMs, the current study excluded tumors larger than 4 cm and patients with bilateral or multiple renal tumors.…”

“…The operation was generally performed via the retroperitoneal approach for posterior-located tumors and transperitoneally for anterior tumors. The Cool-tip RF ablation system (Valleylab, Boulder, Colo., USA) was used for LRFA as previously described [10]. After a brief exposure of the renal tumor, the RFA probe was induced through the abdominal wall and laparoscopic ultrasound was used to guide the insertion of the probe to the desired depth.…”

“…Radiofrequency ablation (RFA) has been increasingly accepted in management of SRMs for its short learning curves, minimal invasiveness, and low complication rates [9]. The number of institutes performing renal tumor ablation has been increased, with encouraging functional and oncological results [10,11,12,13]. A majority of reports are on percutaneous RFA but laparoscopic RFA (LRFA) has also been reported.…”

Objectives: To compare the long-term functional and oncological results between laparoscopic radiofrequency ablation (LRFA) and laparoscopic partial nephrectomy (LPN) in selected clinical T1a (cT1a) renal tumor patients. Methods: We retrospectively analyzed the medical records of patients with cT1a renal tumors who had LRFA or LPN at our institution between February 2006 and February 2015. Student's t test was used to compare the perioperative data between the two groups. Survival analyses were calculated using the Kaplan-Meier method. Results: A total of 179 patients were included in the study. Patients in the LRFA cohort were significantly older and had higher American Society of Anesthesiologists sore than in the LPN cohort. The LRFA group had a significantly lower mean blood loss than the LPN group (p = 0.03). The percent decrease of GFR in the LRFA group was significantly lower than in the LPN group (p = 0.021). The 5-year overall, cancer-specific and disease-free survival were 93.3 vs. 94.6%, 98.0 vs. 98.5% and 97.1 vs. 97.3%, for LRFA and LPN, respectively (all p value >0.05). Conclusions: The excellent perioperative results, long-term functional and oncological outcomes of LRFA confirm that this technique is safe, nephron sparing and oncologically effective for the treatment of cT1a renal tumors.

Recent studies report mid- and long-term oncologic control with thermal ablation for small renal tumors to be equivalent to surgery. Comparisons of cryoablation, radiofrequency ablation (RFA), and laparoscopic approaches to percutaneous approaches report equivalent results. Studies report little or no decrease in renal function after ablation of renal tumors. These studies support the use of percutaneous thermal ablation for treatment of small renal malignancies. Studies also report that percutaneous ablation is a safe and durable treatment of the primary tumor in stage IV patients, ultrasound guidance for percutaneous ablation can be effective, and chyluria is relatively common after RFA. Results were disappointing for newer ablation techniques, including microwave, irreversible electroporation, and high-intensity focused ultrasound. These techniques require improvements before their use in place of RFA and cryoablation. The rates of diagnostic and subtype-specific renal tumor biopsies can be improved by using both aspirate and core techniques.
