The paper aims to present the current approach to solid tumours of the renal parenchyma using magnetic resonance imaging. The authors overview recommended techniques within the multiparametric examination; they offer the recommended examination scheme valid for 1.5 T and 3 T magnetic resonance devices. The authors show an overview of the most common solid renal tumours, both benign and malignant. Morphological peculiarities and similarities are presented; possible differences in the multiparametric magnetic resonance imaging are highlighted The following section shows the recommended ccLS scores to differentiate renal clear cell carcinoma from other tumours with a better prognosis. The discussion presents the recommended procedure and limitations in the point of view of the literary sources. In conclusion, we emphasize the suitability of introducing the ccLS standard into the protocols of magnetic resonance workplaces. The future without administration of a contrast agent is also outlined, especially in patients with kidney's disease. [ABSTRACT FROM AUTHOR]

Introduction: At the time of diagnosis, up to one third of patients with clear renal cell carcinoma have a disseminated disease, and half of patients with the localized disease will progress in the future. Dissemination into the lungs develops most frequently. Purpose: Retrospective analysis of a group of patients undergoing surgery due to pulmonary metastases of clear renal cell carcinoma over a period of twelve years. Material and methods: Between 2001 and 2012, 21 patients, including 14 males, with a mean age of 65.7 years, underwent surgery at the authors' department. Th ose patients who had undergone a radical resection for renal cell carcinoma, who had no extra-pulmonary metastases, and whose pulmonary metastases appeared to be radically removable according to pre-operative assessments, were indicated for the pulmonary metastatectomy. Solitary metastases were found in 11 patients, multiple metastases in the remaining patients. Four patients had bilateral metastases. Th e medial of the symptom-free period since nephrectomy was 24 months. Results: A total of 17 unilateral and 4 bilateral surgeries were performed. Th e most common type of surgery included wedge pulmonary resections (12 procedures). A total of 43 metastases were radically resected. Perioperative morbidity was 9.5% with zero mortality. At the time of publication, 57.1% of those that underwent a metastasectomy were alive, with a with median survival time of 44.3 months. Th ree-year and fi ve-year survival rates in the group were 57% and 49%, respectively. Nine patients (42.9%) are alive aft er the metastasectomy without disease progression; the median was 24 months. Conclusion: The presented results confi rm the positive role of metastasectomy in the treatment of pulmonary metastases of clear renal cell carcinoma. Long-term survival following pulmonary metastasectomy can be expected in solitary, metachronic metastases of a small size with a disease free interval > 1 year following nephrectomy, with the absence of metastases in the regional lymphatic nodes and R0 resection.
