Im Alter unter 50 Jahren sind Nierenzysten selten, ihre Häufigkeit nimmt mit zunehmendem Lebensalter zu. Im Alter unter 29 Jahren sind Nierenzysten bei Gesunden normalerweise nicht nachweisbar, im Alter zwischen 30 und 49 Jahren liegt die Häufigkeit mindestens einer Nierenzyste bei 1,7 %, im Alter zwischen 50 und 70 Jahren 11,5 % und über dem 70.

Smith AD, Remer EM, Cox KL, et al. Bosniak category IIF and III cystic renal lesions: outcomes and associations. Radiology 2012; 262:152. Bosniak IIF lesions vary in appearance: (1) BIIF lesions with minimal findings close to category II in complexity and (2) BIIF lesions that are closer to category III in complexity. M.A. Bosniak has recently suggested that BIIF cysts with minimal findings only need follow-up for 1–2-years, whereas more complex BIIF cysts should be followed for a longer period (e.g., 3–4 years or longer) [ 1 ].

Bosniak 2F type of kidney cysts is one category of the Bosniak classification system of renal cystic masses.The classification system puts renal (kidney) cysts into five categories, depending on the findings on CT. Besides Bosniak 2F, the other four include: Bosniak 1, Bosniak 2, Bosniak 3, and Bosniak 4. Bosniak 2 cyst – <5% risk of cancer, does not require follow-up; Bosniak 2F cyst – 5% risk of cancer, requires follow-up imaging to assess progress; Bosniak 3 cyst – 50% risk of cancer, should be surgically removed or biopsied; Bosniak 4 cyst – 80-95% risk of cancer, should be surgically removed; 4. Follow-up of Bosniak IIF cysts in 60-year-old women with severe comorbidities yielded a LE benefit of 3.9 months; in 80-year-old women with no comorbidities, the benefit was 2.8 months, and with Conclusion: Based on this study, 10.9% (17 of 156) Bosniak category 2F cystic lesions progress to malignancy, and progression occurs within 6 months to 3.2 years.

This classification helps the radiologist to categorize each cystic renal mass as "nonsurgical" (ie, benign in category 1 and 2) or as "surgical" (ie, requiring surgery in category 3 and 4). Renal cysts are classified by malignant risk using the Bosniak classification system.

Bosniak 2 cyst – <5% risk of cancer, does not require follow-up; Bosniak 2F cyst – 5% risk of cancer, requires follow-up imaging to assess progress; Bosniak 3 cyst – 50% risk of cancer, should be surgically removed or biopsied; Bosniak 4 cyst – 80-95% risk of cancer, should be surgically removed; 4. Follow-up of Bosniak IIF cysts in 60-year-old women with severe comorbidities yielded a LE benefit of 3.9 months; in 80-year-old women with no comorbidities, the benefit was 2.8 months, and with Conclusion: Based on this study, 10.9% (17 of 156) Bosniak category 2F cystic lesions progress to malignancy, and progression occurs within 6 months to 3.2 years.

Cirka 1 200 nya fall av njurcancer upptäcks varje år i Sverige.
