Aim. To describe the natural history of small renal mass on active surveillance and identify parameters that could help in predicting the need for intervention in patients with small renal masses undergoing active surveillance. We also discuss the need for renal biopsy in the management of these patients.Methods. A retrospective analysis of 78 renal masses ≤4 cm diagnosed at our Urology Department at Bnai Zion Medical Center between September 2003 and March 2012.Results. Seventy patients with 78 small renal masses were analyzed. The mean age at diagnosis was 68 years (47–89). The mean follow-up period was 34 months (12–112). In 54 of 78 masses there was a growth of at least 2 mm between imaging on last available follow-up and diagnosis. Eight of the 54 (15%) masses which grew in size underwent a nephron-sparing surgery, of which two were oncocytomas and six were renal cell carcinoma. Growth rate and mass diameter on diagnosis were significantly greater in the group of patients who underwent a surgery.Conclusions. Small renal masses might eventually be managed by active surveillance without compromising survival or surgical approach. All masses that were eventually excised underwent a nephron-sparing surgery. None of the patients developed metastases.

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

Percutaneous renal biopsy has become increasingly utilized particularly in patients undergoing active surveillance for small renal masses. We present a case of a significant complication following biopsy of a solid renal mass in a patient who was recently diagnosed with laryngeal squamous cell carcinoma. The patient was planned for nephron sparing surgery that was converted to radical nephrectomy due to extensive renal infarction secondary to significant subcapsular hemorrhage inflicted by the biopsy.

Introduction. Angiomyolipoma is a common benign renal tumor. It is associated with Tuberous Sclerosis Complex (TSC) in 20% of patients. Angiomyolipomas are classically multiple, bilateral, and growing; they may lead to complications such as Wunderlich syndrome or, in rare cases, to venous extension.Observation. a 74-year-old woman with TSC presented with an angiomyolipoma of the right kidney with inferior vena cava (IVC) fatty thrombus. She underwent partial nephrectomy and thrombectomy. After a 7-year follow-up there was no evidence of recurrence or metastasis and her renal function was preserved.Review of Literature. It is the 44th reported angiomyolipoma associated with IVC thrombus. The mean size of angiomyolipomas was 86.1 mm and 67.4% of patients were symptomatic. Pulmonary embolism was found in 6 patients. There were 2 cases of recurrence/metastatic outcome after radical nephrectomy and thrombectomy. They were associated with epithelioid form. The mean size of epithelioid tumors was significantly bigger than in classical angiomyolipomas (127.1 mm versus 82.6 mm,P=0.037). With a median follow-up of 12 months, 91.3% of patients were recurrence and metastasis free, with 3 cases of nephron sparing surgery.Conclusion. Nephron sparing surgery for angiomyolipoma with IVC fatty thrombus can be safely performed in TSC, even in sporadic angiomyolipoma.

Interest in surveillance for small renal masses has expanded exponentially due to incidental detection with increased imaging. However, some of these small renal masses behave aggressively. Sarcomatoid pathology is associated with a worse prognosis. Traditionally, it has been thought of as a common pathway of dedifferentiation once a renal malignancy of any histology reaches a threshold size of approximately 3 cm. We report a case of a 65-year-old male with a 2 cm sarcomatoid renal cell carcinoma. To our knowledge, this is the smallest tumor with sarcomatoid differentiation reported in the literature.

e16139 Background: To present our experience with elective, open, nephron-sparing surgery for renal masses in a contemporary, consecutive series. Methods: In this retrospective study, records of all patients who underwent elective nephron-sparing surgery (E-NSS) between March 1997 and December 2007 at our institution were reviewed. The preoperative workup included laboratory analysis, renal ultrasonography and abdominal computed tomography. The histological findings, complications, and oncologic outcome were studied. Results: A total of 231 E-NSS were performed in 223 patients (82 females,141males; mean age 64 years). 62 “hot ischemia” procedures and 169 “cold ischemia”. The mean tumor size was 4.6 cm (1.1–12cm). 52 patients presented renal masses > 4cm. Renal cell carcinoma was present in 177 patients (76.6%), benign renal masses were diagnosed in in 54 pazienti (23.3%): angiomyolipoma (35%), oncocytoma (40%), complicated cyst (25%). Worthy of note among these 54 patients, pre-operative diagnosis was present in 12 patients. Moreover, 17 benign lesions (31%) were > 4 cm. Complication rate was 5.3% (12 pts): splenectomy (2.2%), nephrectomy because of postoperative bleeding (0.8%), urinary fistulas (0.8%). After a median follow-up of 84 months (range 5 to 120), no patient had developed local recurrence, 19 (8.9%) died for other causes, 2 (0.9%) died for other tumor. Conclusions: The results of this contemporary, monocenter experience underline the role of open, elective, nephron-sparing surgery for patients with renal masses, confirming good results even for renal masses > 4cm. These conclusions are particularly important considering that benign histologic findings were present in almost one forth of patients. No significant financial relationships to disclose.
