Surgery of primary retroperitoneal tumours.

Upon detecting 112 retroperitoneal space-reducing processes the authors operated on 62 adults with primary retroperitoneal tumours (12 benign and 50 malignant). The diagnostics and complex therapy of these tumours are dealt with. It is established that although the CR, MRI and USG have resulted in a considerable development, the therapeutic results are still not much better. In the surgical management of benign lesions total tumour extirpation is recommended even with extensive multivisceral resections. For tumours of low grade malignancy the authors have the same standpoint. In case of PRTs of high grade malignancy ― and a considerable number of patients belongs to this group ― the ultraradical interventions are not associated with promising results and therefore are not recommended by the authors
