The aim of this study was to describe the characteristics of positron emission tomography (PET) molecular imaging combined with low-dose computed tomography (CT) in small renal mass (SRM) treated with cryoablation (CA). Currently, treatment success is defined by the absence of contrast enhancement at CT. However, the use of contrast is relatively contraindicated in patients with renal function impairment, mandating alternative follow-up strategies. Several reasons were identified as criteria for performing PET-CT before and/or after SRM-CA in 9 patients, and the results were retrospectively studied. The histology revealed renal cell carcinoma in 7 patients andoncocytoma in 2 patients. In 6 patients, a PET-CT was performed before and after CA. In one patient, the PET-CT was performed only before CA and in 2 patients only after CA. Before CA, clearly there was metabolic uptake of fluorine-18 fluorodeoxyglucose (18F-FDG) in the SRM in all patients. Following CA, the absence of 18F-FDG uptakes in the SRM could clearly be noticed. However, the tracer cannot always be distinguished from focal recurrence or reactive inflammatory tissue. In one patient, asymptomatic metastatic bone lesions were noticed when performing PET-CT at follow-up. This pilot study with 18F-FDG PET-CT for the follow-up of SRM cryosurgery showed that 18F-FDG PET-CT imaging could be used to characterize cryoablative tissue injury at different times after CA.

The rise in incidentally discovered enhancing solid renal tumors has spurred the development of new approaches to managing this unique clinical entity known as the small renal mass (SRM). These approaches are grounded on a better understanding of the natural history of SRM, with the goal to reduce the morbidity associated with their management and avoid overtreatment. In this chapter, we review the body of evidence pertaining to the classification and clinical management of SRMs with respect to diagnosis, treatment, and follow-up. In addition, we discuss the controversies and active areas of development for this rapidly evolving field that strides towards a precision medicine paradigm.  This review contains 6 figures, 6 tables and 63 references Keywords: Small renal mass, renal cell carcinoma, radical nephrectomy, renal tumor biopsy, active surveillance, natural history, oncocytoma, robotic surgery, partial nephrectomy

Objective: The aim of this study is to evaluate the outcome of ablation therapy in our clinic for the treatment of patients with small renal mass Materials and Methods: We retrospectively evaluated the technic and follow-up data of 30 patients with 36 tumors who underwent Radiofrequency Ablation (RFA) and Microwave Ablation (MWA) in our clinic. Demographic data, ablation type, tumor characteristics, peroperative and postoperative complications and treatment success of the patients were evaluated. Results: A total of 36 tumors who underwent ablation treatments, 23 were treated with RFA, 13 with MWA. The mean tumor size was 28.9 ± 6.92 mm in RFA and 29.3 ± 7.70 mm in MWA. 12 (52.1%) of the RFA procedures were applied to the right kidney while 11 (47.8%) were applied to the left kidney. 6 (46.1%) of the MWA procedures were performed on the right kidney and 7 (53.8%) on the left kidney. Of the 36 tumors, 4 (11.1%) were located central and 32 (88.8%) were peripheral. Complications occurred in 2 patients. In one of these patients, acute renal failure and urea creatinine were found to be elevated. In the other patient, local pain was found in the ablation side and minor bleeding was detected at the ablation site in USG. The mean follow-up period was 49.6 ± 24.7 months in patients with RFA and mean follow-up was 16 ± 8,05 months in MWA treatments. The overall success in MWA administration was calculated as 76.9%, while the overall success in RFA was 80%. Conclusion: Long-term oncologic efficacy of RFA appears to be successful in the treatment of T1a renal carcinomas. Further studies can be conducted to elucidate the influence of MWA on long-term oncological outcomes.
