[Renal oncocytoma and its morphology, diagnosis and therapy]. / Onkocytóm oblicky a jeho morfológia, diagnostika a liecba.

Oncocytoma includes 3-5% of all renal tumors. It does not manifest itself by typical symptoms and often is diagnostically confirmed in coincidence with examinations of other diseases. The preoperative diagnosis of oncocytoma is difficult. Oncocytoma must be taken into consideration in cases of bilateral multilocular tumors of the kidney. Neither RTG, USG and CT examinations, nor angiography give the specific picture of oncocytoma. One of the possibilities of diagnosis confirmation is the peroperative biopsy. If the latter confirms the diagnosis, then according to possibilities, operation with maintenance of unimpaired renal parenchyme should be performed. The prognosis of the disease is good and depends on the stage of cellular differentiation of tumor. The study presents observations of 4 patients subdued to surgery at the Urologic Clinic FHwP in Kosice since 1981 to 1990. The patients survive without metastases for 3-4 years.

[Correlation of urography, ultrasonography and computer tomography with clinical findings in examinations of the kidneys and retroperitoneum. Possibilities of diagnostic errors]. / Korelácia urografie, ultrasonografie a pocítacovej tomografie s klinickým nálezom pri vysetrení obliciek a retroperitónea. Moznosti diagnostických omylov.

The authors prospectively and retrospectively mutually compared the diagnostic value of urography, ultrasonography (USG), and computer tomography (CT) in four patients, with the diagnosis misstated prior to operation. The most valuable findings were provided by CT. Mere utilization of these methods does not exclude the possibility of diagnostic misstatements. In three patients the ultimate diagnosis was assessed on the basis of operative revision and in one patient, by means of cytologic examination of the renal punctate. Owing to retrospective evaluation of examinations, diagnostically valuable symptoms which could have lead to the correct diagnosis, were distinguished. Hence, examinations must necessarily be evaluated in complex with the general clinical state. (Fig. 6, Ref. 14.).

[Seminal vesical abscess-diagnosis and therapy]. / Absces semenných mechúrikov--diagnostika a liecba.

The authors present case-histories of two patients with abscesses of the seminal vesicles. They emphasize the asset of transrectal ultrasonographic examination for the early diagnosis of an abscess of the seminal vesicles. Antibiotic therapy, puncture of the seminal vesicles and evacuation of pus proved effective therapeutic methods.
