Cystic renal masses were usually detected in incidental imaging examinations, and the rational treatment of these masses may be challenging. The definition of “cystic” in imaging is a mass which has a mostly fluid-filled spaces more than one-fourth of the lesion. 1 Cystic renal mass account for nearly 15% of all renal mass lesions. While, malignant cystic renal lesions prefer to better

o Of the Bosniak IIF lesions – after median follow up of 15 months (range 3-98) 12 cases (14.8%) progressed in radiological complexity with a median time to progression of 11 months (3-98 The Bosniak renal cyst classification was introduced in 1986. This classification was based on computed tomography (CT). In the course of years several adjustments were proposed. The current classification contains five categories: I, II, IIF, III and IV. Categorie I and II lesions are assumed benign and do not require further treatment.
Njurcyster är enkla (I Bosniak) och komplexa (II, IIF, III och IV Bosniak). Endast ibland registrerade cystisk lesion av båda organen som avlägsnar urin.
This classification of renal cystic lesions was produced in an attempt to standardize the evaluation of the condition across all imaging modalities. Association with Bosniak category was explored.

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 3 cysts were subclassified as 3s—septated enhancing Bosniak cysts and 3n—cysts with wall or septation‐only nodularity. A multivariate Cox proportional hazards model was used to identify predictors of the Bosniak classification change. Kaplan‐Meier curves were applied to analyze Bosniak cyst progression and regression. Figura 12. Quiste categoría IIF de Bosniak.
Bosniak category I and II are composed of benign lesions with minimal complexity and can reliably be left alone (Figure 3). Bosniak III and IV lesions require

Bosniak category III cystic renal lesions are indeterminate in malignant potential and most commonly managed with surgical excision. While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% (2), reported malignancy rates range from 31% (3) to 100% (4). The Bosniak classification is widely used by radiologists and urologists for addressing the clinical problem assessing renal cysts 3.
CT and histological findings of 19 Bosniak III cysts were correlated. Mean lesion size was 4.6 cm (range, 1.1–8.1 cm) for Bosniak category III lesions and 3.5 cm (range, 1.2–22.0 cm) for Bosniak category IV lesions. The mean size of malignant lesions was 4.1 cm, and that for benign lesions was 3.4 cm, with no significant statistical difference noted ( p = 0.387).

some small renal masses are cystic in nature. the bosniak classification is used to classify these lesions, approximate risk of malignancy and direct management.13 Table 3 lists the bosniak classification and Table 4 outlines the basic management and follow up plan for patients in each of the bosniak classifications.

Slightly more than half of Bosniak III renal cysts and most Bosniak IV renal cysts are malignant at surgical pathology [1–3, 10, 11]. The mean largest diameter was 48.7 ± 28.8 mm. All lesions were multilobulated and septated. Of the 19 removed lesions, 16 (84%) were malignant, and 3 (16%) were benign (one inflammatory cyst including a nephrolith, one cystic nephroma and one atypical angiomyolipoma).
2021) have widespread validation. Biopsies from seventeen Bosniak 3 cystic lesions were pathologically analyzed and five (29%) were found to be malignant. Conclusion: Our results reveal a considerable malignancy rate among both 2015-05-19 The Bosniak classification of cystic renal masses (version 2019), or usually simply Bosniak classification, version 2019, is a proposed update of the classic/current Bosniak criteria.The update hopes to improve on the classification's predictive power for malignancy and minimize the number of benign lesions undergoing treatment. 2010-08-19 2010-01-21 2011-02-07 All Bosniak III lesions were of low Fuhrman grade with no evidence of progression. No patient in this study developed metastatic disease within the three-year followup period. Smaller (<4 cm) Bosniak III cysts were more likely to be malignant and lesion size should be taken into consideration when considering management of complex cysts.
