[Ultrasonic diagnosis in selecting the treatment method for varicocele]. / Ul'trazvukovaia diagnostika v vybore metoda lecheniia varikotsele.

The paper deals with ultrasound diagnosis as a modality able to recognize indications either to surgical or endovascular treatment of varicocele. Forty-two patients aged 12-28 with varicocele degree I-III were examined using sector ultrasonic transducers (3.5,5 MHz) which visualized renal and internal testicular veins. Relevant ultrasonic and phlebographic findings were compared. The impossibility to predict outcomes of the endovascular treatment is attributed to the absence of primary information on the structure of the renotesticular portion of varicocele patients' venous bed. Ultrasonography can provide such information. The detection rate of multiple internal testicular veins and other renotesticular anomalies appears rather high.

[Diagnostic prospects of angiography in pyo-destructive processes in the kidney]. / Diagnosticheskie vozmozhnosti angiografii pri gnoino-destruktivnykh protsessakh v pochke.

The article is devoted to search for indications and more exact differential diagnostic criteria of angiographic methods of diagnosis of pyo-inflammatory diseases of the kidney. Of most informative value is the selective renal arteriography and pharmacophlebography which gave more exact differential diagnostic criteria.

[Indices of testicular endosecretory function and of the status of the hypophyseal-gonadal system in varicocele]. / Nekotorye pokazateli vnutrisekretornoi funktsii iaichka i sostoianiia gipofiz-gonadnoi sistemy pri varikotsele.

Testicular intrasecretory function and gonad-hypophyseal regulation were studied in 28 patients with the left-sided varicocele whose age varied from 11 to 36 years. Radioimmunoassay was used for the assessment of testosterone, estradiol, progesterone, follicle-stimulating (FS) and luteinizing (L) hormones and prolactin levels in the blood samples from femoral and internal testicular veins taken during endovascularization of varicocele. With regard to the age and manifestations of the secondary sexual signs the patients were divided into three groups. The first group (11-12-year-old) enrolled the patients with normal age-related levels of FS and L hormones in the presence of hyperprolactinemia. The positive testiculoperipheral gradient was revealed in 3 cases for estradiol and in 2 patients for testosterone and progesterone. The peripheral blood testosterone was normal in all the patients whereas estradiol and progesterone were decreased in 2 and 4 cases, respectively. All the patients of the second group (13-15-year-old) demonstrated an increase in testicular blood testosterone and estradiol as compared to their levels in the peripheral blood (1.46-1.8-fold and 1.3-7.1-fold, respectively). In 6 patients, this ratio was 1.65-2.33-fold higher. The levels of FS and L hormones were normal. In all cases hyperprolactinemia was observed. The third group (16-36-year-old) patients demonstrated a 1.4-3.1-fold gradient of testosterone in the testicular blood versus its levels in the peripheral blood. The authors defined 1.1-239-fold (mean, 8.95) estradiol gradients and 0-979-fold (mean, 2.5) progesterone gradients. In all cases but one, the levels of FS and L hormones were equal to the control.(ABSTRACT TRUNCATED AT 250 WORDS)

[Functional status of the right heart in patients with nephrogenic hypertension]. / Funktsional'noe sostoianie pravykh otdelov serdtsa u bol'nykh s nefrogennoi gipertenziei.

Marked hemodynamic disorders in the right heart were demonstrated in patients with nephrogenic arterial hypertension: they were high diastolic blood pressure and the right-ventricular hypodynamic syndrome, dependent on the duration of underlying disease and aortic diastolic blood pressure level.

[Endovascular electrosurgery of varicocele]. / Endovaskuliarnaia élektrokhirurgiia varikotsele.

A new method of treatment of varicocele is described consisting in the endovascular electrocoagulation of the internal testicular vein in order to interrupt reno-testicular reflux resulting from insufficiency of the internal testicular vein valves. The endovascular electrocoagulation of the internal testicular vein was fulfilled via either a retrograde or an antegrade access. The endovascular electrocoagulation of the internal testicular vein was made in 49 patients with a left-side varicocele. In 38 of them coagulation was performed via a retrograde access, in 11 patients an antegrade access was used. The method is less traumatic and possesses both a diagnostic and curative value.
