[The conservative surgical treatment of kidney tumors].

Seven cases are reported of patients with renal tumors in whom organ-preserving operations were performed. Two patients had only one kidney, the contralateral had been removed in the past. They had only partial resection of one third of the kidney performed. In five patients, in whom parenchymal renal tumor was accidentally detected, with normal contralateral kidney, enucleation of the tumor was performed. On histologic examination one had hypernephroma, three--adenoma with atypism, one--leiomyoangiolipoma. The size of all enucleated tumors varied from 25 to 55 mm with distinct fibrous pseudocapsule, without proliferation in it and without vascular invasion of the neoplastic process. It is assumed that patients with tumor of the only kidney when possible should be subjected to organ-preserving operation. In the event of a small encapsulated tumor and normal contralateral kidney, organ-preserving operation may be performed when there is low-grade malignancy.

[Endorectal ultrasonic study of the prostate].

Endorectal ultrasound examination, which has been developed mainly by Japanese and Danish scientists is being applied at I. Clinical Hospital "Dr. Kiril Khavezov" in Sofia since 1984. In this report the method is briefly described and results presented of 91 examinations performed in 76 patients with miscellaneous prostate diseases: 55 patients with adenoma, 17 with cancer, 3 with prostatitis and 1 with abscess. Characteristic of adenoma were the changes in the size and form of the gland; two types of changes in the form are described. Various structural changes, associated with asymmetry and impaired integrity of the prostate capsule were seen in cancer. In cases of prostatitis the gland was enlarged without structural changes. Only the the abscess was visualized as a liquid zone with irregular shape. The value of this method is that it furnishes information on the morphologic pattern of the whole gland, as well as on its correlations with the adjacent structures. Endorectal ultrasound examination of the prostate can not be a substitute for the cytologic and histologic methods when a neoplastic process is suspected.

[Potentials and limits of ultrasonic diagnosis in gastroenterology].

The great diagnostic value of ultrasonic tomography in the diagnosis of liver, biliary, pancreatic, gastric, intestinal, abdominal and retroperitoneal disease is reviewed and proved. Best results can be achieved in the indications for its application and the potentialities of the method are well known. The sonographic results should always be assessed with the clinical, laboratory and other instrumental data. The faulty diagnoses are due not to the method itself but to the incompetent interpretation of the sonographic images and to the lack of knowledge for the scope and limitations of sonography.

[Ultrasonic characteristics of echinococcal cysts].

The results from an ultrasound examination of 55 patients with positive hydatid cysts were retrospectively discussed. The total number of the cysts was 79, because some of the patients had two and more cysts. Four types of images were described: simple cysts, cysts with daughter cyst, echogenic and calcified. The connection between the ultrasound image and individual characteristics of the cysts were looked for.
