Both studies have suggested that this approach could be safely used in this population, with only one death due to kidney cancer observed after 5 years of follow-up in these studies.

Bosniak category III cystic renal lesions are indeterminate in malignant potential and most Bosniak III indeterminate cystic mass. thickened irregular or smooth walls or septa with measurable enhancement; treatment/work-up: partial nephrectomy or radiofrequency ablation in poor surgical candidates ref; percentage malignant: ~55% 6; Bosniak IV. clearly malignant cystic mass High Prevalence of Benignity among Bosniak III Cystic Masses. Approximately half of resected Bosniak III masses are malignant, with rates in individual series ranging from 25% to 100% (12,34,35,62). The converse is that approximately half of all resected Bosniak III masses are benign, resulting in potential harms of surgery with no clinical benefit. Class III "Bosniak III cystic renal mass.

A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy. Numerous renal cysts are seen in the cystic kidney diseases, which include polycystic kidney disease and medullary sponge kidney.

The wall and/or septa may contain calcifications. Bosniak III cysts carry a 50-70% risk of cancer. Bosniak IV cysts carry a 90-100% risk of cancer.
