[Endoscopic recanalization in treating ureteral obliteration].

For diagnosis of urethral obliteration we have developed a method of complex examination including x-ray and ultrasound investigations, NMR-tomography of the small pelvis and perineum. This method provides maximal significant information about defects in the urethra and adjacent tissues and organs. Endoscopic urethral recanalization was performed in 86 patients with urethral obliteration aged from 7 to 78 years.

[The endoscopic treatment of extensive urethral strictures and obliteration of the urethra and bladder neck].

Extensive urethral strictures, obliteration of the urethra and bladder cervix are thought to be the most complicated urological diseases. They occur more frequently in young and middle-aged persons consequently to pelvic and perineal traumas or they are complications of surgical interventions. Open surgery often cause complications such as suppuration of the operative wound, emergence of urinary fistulas, enuresis, recurrence of the structure or obliteration.

[The use of crystallography in the diagnosis of diseases of the thyroid gland].

In 67 patients at the age of from 23 to 69 years with different hyperplastic processes in the thyroid gland, the crystallographic investigation of the blood serum was carried out. The crystallograms varied depending on the character of a disease and functional state of the thyroid gland. Simplicity and informative value of the method permit to recommend it for wide use in the diagnosis of the thyroid gland diseases.
