The incidence of the small renal mass continues to increase owing to the aging population and the ubiquity imaging. Most of these tumors are stage I tumors. Management strategies include surveillance, ablation, and extirpation. There is a wide body of literature favoring nephron-sparing approaches. Although nephron-sparing surgery may yield decreased long-term morbidity, it is not without its drawbacks, including a higher rate of complications. Urologists must be attuned to the complications of surgery and develop strategies to minimize risk. This article reviews expected complications of surgery on renal masses and risk stratification schema.

Solitary fibrous tumors are well described in the pleura, but rare extra-pleural neoplasms have been reported. We describe a patient with a solitary left renal fibrous tumor who after undergoing a nephrectomy, presented 8 years later with a contralateral metachronous solitary fibrous tumor. Malignant metastatic extra-pleural solitary fibrous tumors are extremely rare, and to our knowledge, this is the first case of contralateral recurrence of solitary renal fibrous tumor. The patient underwent a robotic assisted partial nephrectomy of the right renal mass. Both tumors showed overlapping histopathology.
