The Bosniak classification system has been widely used by radiologists and urologists, having recently been found to be also suitable for use in the evaluation of renal cysts on MRI scans (7, 11-14). Although there have been many studies evaluating the malignancy rates of category III and IV cysts ( 2 , 4 , 6 , 7 ) , few studies have evaluated the malignancy rates and progression of category

RESULTS: 121 patients (84:37 M:F) were identified with 136 renal lesions (84, 37 and 15 Bosniak category 2F, 3 and 4) and followed for 1-12.3 years (mean 3.5 years). 87% (73/84) of 2F lesions were downgraded or remained stable. 48% (25/52) of 3/4 lesions were downgraded.

Summary of evidence and recommendations for surveillance following RN or For the diagnosis of complex renal cysts (Bosniak IIF-III) MRI may be an option.

Conclusions: A diagnostic change in Bosniak 3s and 2F cysts is common and Bosniak 3n cysts behave more like Bosniak 4 cysts. Objective: The purpose of this study was to determine the percentage of small (< 4 cm) Bosniak category 2F, 3, and 4 lesions that regress during active surveillance. Materials and Methods: We retrospectively reviewed the records of patients with complex renal cysts categorized as a Bosniak IIF or III. Surveillance imaging and pathological outcomes of category IIF cysts were recorded to determine radiological predictors of progression. Based on our surveillance strategy of Bosniak IIF masses, we recommend computed tomography (CT)/magnetic resonance imaging (MRI) every 2 years after the initial examination.

The aim of this study was to investigate the surveillance and clinical outcome of Bosniak IIF renal cysts. We searched for retrospective evidence of Bosniak IIF renal cysts, cystic renal lesions, Bosniak IIF lesions, Carcinomas, Renal Cell, and Malignant Neoplasms obtainable up to April 2019. We selected articles published in English.

Our data suggested that ceasing radiological follow-up surveillance after a minimum of two years of stable surveillance could be considered.

Conclusions: A diagnostic change in Bosniak 3s and 2F cysts is common and Bosniak 3n cysts behave more like Bosniak 4 cysts. 2013-03-26 · Surveillance images of Bosniak IIF were reviewed to determine radiological progression and clinical outcomes. Results: Forty patients with 42 category IIF cysts were included in our study (median age 68 years (range 38–88 years), median follow-up of 29 months (range 5–77 months)).

May 5, 2020 The Bosniak classification or determination of renal cyst complexity was initially used to aid in differentiating non-surgical (categories I, 2II, and IIF) Dec 17, 2020 It has also been shown that surgical pathology of stable Bosniak IIF cysts is malignant in less than 1%, while the cysts, which are upgraded to Jan 21, 2020 The aim of imaging surveillance is to detect Bosniak IIF renal cysts that progress to higher class lesions, because higher reclassification is linked or continuous surveillance still represents a major challenge to the clinician, The Bosniak classification of complex cystic renal masses has been applied in In 36 renal malignant lesions, 33 masses (Conventional US: Bosniak I The Bosniak class I lesion accounted for 7,559 or 91.0% of the cysts whereas 744 We defined Bosniak class I and II (including IIF) lesions as simple renal cysts in Active Surveillance Versus Nephron-Sparing Surgery for a Bosniak I Mar 8, 2018 Sixty-five patients underwent surgery or ablation (either immediately or during subsequent imaging surveillance): 10 of 185 Bosniak IIF patients IIF. Because of their 5%-10% malignancy risk, follow-up for Bosniak IIF masses consists of radiographic surveil- lance with computed tomography or magnetic Active Surveillance (AS). For patients with small solid or Bosniak 3/4 complex cystic renal masses, especially those <2cm, AS is an option for initial management.

Postoperative pathology examination revealed a multilocular cystic renal cell carcinoma. Resection of the Bosniak 2F cyst provides 2 advantages: the recipient receives a new donor kidney and will be free of dialysis, and the donor will be free of surveillance.

Aug 27, 2020 The rate of progression of Bosniak IIF cysts is low, and malignant cysts progress early during surveillance.

Algorithm for bosniak 2f cyst in kidney donation. American Journal of Case Reports , Volume 18 p. 733- 738. Background: The Bosniak system for radiological classification of renal cysts offers a tool for surgical decision-making in clinical practice. Although 95% of Bosniak 2F cysts remain benign, a consensus on the management of Bosniak 2F

The aim of imaging surveillance is to detect Bosniak IIF renal cysts that progress to higher class lesions, because higher reclassification is Radiological progression of Bosniak IIF cysts is low and progression to malignancy lower still, typically occurring within 24 months of diagnosis. Our data suggested that ceasing radiological follow-up surveillance after a minimum of two years of stable surveillance could be considered. Blue curves indicate Bosniak 2f. Surveillance renal US did not detect a stage change and in 1 case it ultimately delayed the diagnosis of a true Bosniak 3 cyst, which was 2F on US. In 3 cases of Bosniak 2F cysts the septations became more nodular and the cysts progressed to 3n. To determine percentage of Bosniak category 2F complex cystic renal masses that progress to malignancy based on serial follow-up studies,and to determine if there are demographic and/or imaging features associated with progression. The growth rate of 3n and 2F cysts was 0.19 and 0.11 cm per year (p = 0.0493 and 0.0327, respectively). Locally advanced or metastatic disease did not develop in any patient.

At a median followup of 15 months 14.8% of Bosniak IIF lesions progressed in complexity with a median time to progression of 11 months (maximum greater than 4 years).
