long a patient with a Bosniak IIF lesion should undergo radiological surveillance – as such any recommendations that can be made are based on expert opinion from the published literature • Literature has been provided to support the view that these patients should undergo surveillance for 5 years although in 2009 O’Malley et al

In most other instances, intensive surveillance intervention was the primary line for Bosniak Category IIF control, while surgical excision was seen for younger patients or those who fear renal cell carcinoma and its consequences. 11 Bosniak IIF renal cysts are often screened until its usually integral.

Microsimulation model of CT versus MRI surveillance of Bosniak IIF renal cystic lesions: should effects of radiation exposure affect selection of imaging strategy? Kang SK(1), Turan EA, Eisenberg JD, Lee PA, Kong CY, Pandharipande PV.

Conclusions: We present a practical guideline for kidney donors with Bosniak 2F cysts, 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. Conclusions: We present a practical guideline for kidney donors with Bosniak 2F cysts, balancing the risk of tumor trans- Bosniak 2F depicts complex cystic lesions with complexity between Bosniak 2 and Bosniak 3 lesions and may have malignant potential in up to 5% of the cases. The Bosniak 2F category allows for non-invasive monitoring of complex renal cystic lesions. The authors conclude that septated cysts (2F and 3s) should be surveilled at 1, 3, and 5 years.

Diagnostic change among Bosniak 3s and 2f cysts is common; Bosniak 3n cysts behave more like Bosniak 4s. Most complex kidney cysts can be safely monitored without intervention, diagnostic change is frequent, and interval imaging between studies should be increased. Presented by: Deepak Pruthi, MD, San Antonio, TX, USA Bosniak IIF renal cysts, the American College of Radiology (ACR) recommended that CT or MRI exams, should be conducted without IV contrast at 6-12 months, following diagnosis for a period of five years. 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.

Abstract: Bosniak 2F renal cystic lesions feature morphologic characteristics between Bosniak I and III categories, the majority of which remain benign.

In our opin-ion there are good arguments to imply surveillance for Bosniak III cysts < 4 cm, similar to the approach of IIF le-sions. 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).

Our data suggests that it is safe to discharge patients with stable cysts after 2 years of surveillance. Adhering to follow-up protocols can alleviate pressure on radiology and urology services. 2017-06-01 2019-01-10 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. 2016-06-20 To better characterize the frequency of Bosniak cyst class changes and identify predictors of change and progression.

The purpose of this study was to determine the percentage of small (< 4 cm) Bosniak category 2F, 3, and 4 In most other instances, intensive surveillance intervention was the primary line for Bosniak Category IIF control, while surgical excision was seen for younger patients or those who fear renal cell carcinoma and its consequences. 11 Bosniak IIF renal cysts are often screened until its usually integral. The 2F category has allowed for the safe nonoperative monitoring of complex cystic renal lesions, but the risk of malignancy and how long lesions should be followed remains unclear in this category. 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. Diagnostic change among Bosniak 3s and 2f cysts is common; Bosniak 3n cysts behave more like Bosniak 4s.

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 Keywords: Bosniak 2F type of kidney cysts; Bosniak 2F; Bosniak 2F type of renal cysts. * The Content is not intended to be a substitute for professional medical advice, diagnosis, or treatment.

Se hela listan på urofrance.org Approximately one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and the majority (88%) of small Bosniak category 2F lesions regressed or remained stable during active surveillance. Therefore, small size should be a consideration for conservative management.

In the present study, the rate of progression for Bosniak category IIF cysts was 4.6 %, which is slightly lower than that reported in previous studies(-), including a

87% (73/84) of 2F lesions were downgraded or remained stable. 48% (25/52) of 3/4 lesions were downgraded.

The Bosniak classification is a time-proven method for the imaging classification and management of these lesions. Knowledge of the pathognomonic features of certain benign Bosniak 2F/3 lesions is important to avoid surgery on these lesions (e.g., localized cystic disease, renal abscess). Bosniak 2F Renal Cysts The Bosniak system is used to classify cystic renal masses seen on imaging, and the classification is shown in the table below. The Bosniak Classification (Warren, & McFarlane 2005) It is usually easy to differentiate between lesions at the ends of the spectrum, i.e.
