Abstract:
Surgical treatment is the main therapy for patients with renal cell carcinoma. The current approach in the treatment of kidney tumours has become widely introduced into nephron-sparing surgery. This approach is usually applied in cases of complex surgeries for large-size tumours with intravenous extension, multifocal, and intraparenchymal renal tumours. The purpose of the study was to investigate the results of nephron-sparing surgery for intraparenchymal renal tumours. Material and methods. The results were obtained in the process of nephron-sparing surgery treatment of 701 patients with rena

Abstract:
Kidney tumors, also known as renal tumors, are tumors, or growths, on or in the kidney. These growths can be benign or malignant cancerous . They may be discovered on medical imaging incidentally i.e. anincidentaloma , or may be present in patients as an abdominal mass, hematuria, abdominal pain, or manifest first in aparaneoplastic syndrome that seems unrelated to the kidney. The most common form of kidney cancer in adults is renal cell carcinoma. Renal cell carcinoma usually does not cause obvious symptoms, especially in the early stages. As a result, the cancer may not be discovered until i

Abstract:
Kidney tumours are among the most common solid malignant pathologies in children, accounting for 6 % of all childhood malignancies. About 89 % of these tumors are nephroblastomas (Wilms' tumors). Renal cell carcinoma in children is extremely rare, representing less than 1 % of all renal tumor pathologies in childhood and adolescence. Given the rarity of this pathology in children and the small size of neoplasms in the renal parenchyma, differential diagnosis between renal cancer and cystic renal lesions can be challenging.

Primitive neuroectodermal tumors exist as a part of the Ewing sarcoma/primitive neuroectodermal tumor family. These tumors most commonly arise in the chest wall and paraspinal regions; cases with a renal origin are rare entities, but have become increasingly reported in recent years. Although such cases occur across a wide age distribution, the average age for a patient with a renal primitive neuroectodermal tumor is the mid- to late 20s, with both males and females susceptible. Histologically, these tumors are characterized by pseudorosettes. Immunohistochemically, CD99 is an important diagno

Abstract:
Papillary renal cell carcinoma (RCC) is known by the tendency to avascularity shown by angiography. More uncommon is the cystic variant of papillary RCC called cystoadenocarcinoma. The majority of papillary tumors are in stage I. The survival for papillary RCC is significantly higher than that for non-papillary RCC. CT-scan MNR, although non diagnostic, enhance the suspicion of a heterologous process in so called “complicated cysts”. US-guided percutaneous needle aspiration may be helpful to diagnose these tumours. We report 2 cases of cystodenocarcinoma and our considerations.
