Abstract
The increase in the detection of small renal masses (SRMs) and their best knowledge leads to a change in the therapeutic management of these lesions. The use of a less aggressive surgical technique or even an expectant attitude is the current tendency, in order to preserve as much renal function as possible. Imaging techniques are essential in the followup of these lesions. It allows us to know the postsurgical changes and possible complications due to treatment and the presence of local recurrence and metastases. Furthermore, a close radiological followup of SRM related to ablative treatments is mandatory. The purpose of this article is to reveal the imaging features of complications due to surgical or ablative treatments, local recurrence and metastasis, as well as their followup.

The increase in the detection of small renal masses (SRMs) and their best knowledge leads to a change in the therapeutic management of these lesions
A postoperative prognostic nomogram has been published predicting recurrence for patients with conventional clear cell renal cell carcinoma [7], and it can be useful for patient counselling, clinical trial, and effective patient followup strategies
The standard treatment for renal cell carcinoma was, for many years, radical nephrectomy, but over the past 10 years, there has been a trend toward the use of nephron-sparing surgery to treat renal cell carcinoma
Summary
Several authors have reported that small incidentally detected tumors are associated with better survival outcomes. The 5-year disease-free survival rate for incidental renal tumors of
