[Role of transvesical ultrasonic scanning in the diagnosis of causes of ureteral stenosis in patients with cervical cancer].

gamma-Beam therapy of combined radiation therapy are frequently followed by ureteral obstruction, caused by a cervical cancer recurrence or pelvic postradiation fibrosis. The knowledge of a cause is very important for a choice of therapeutic tactics of obstructive uropathy. The purpose was to define the potentialities of transvesical ultrasound scanning (TVUSS) in order to reveal causes of disturbed urodynamics of the urinary tracts after radiation therapy of cervical cancer. TVUSS was performed in 17 women with a confirmed diagnosis. It turned out that a cervical cancer recurrence could be differentiated from postradiation fibrosis by specific ultrasound signs. Another group of 44 patients was investigated using this method to find out causes of disturbed urodynamics of the upper urinary tracts: postradiation pelvic fibrosis was noted in 7 patients, a recurrence of cervical cancer--in 19, a recurrence of cervical cancer with the involvement of the urinary bladder--in 11, and bladder carcinoma--in 3, in 3 other cases the diagnosis was not established as a result of difficulties in interpreting sonograms.

[The role of transperitoneal fine-needle aspiration biopsy in the diagnosis of obstructive uropathy in patients with cervix uteri cancer].

Upon the exposure to remote or combined radiotherapy, the patients with uterine cervical cancer often develop ureterostenosis due to recurrence or postradiation alterations in the walls and adjacent tissues of the ureter. Etiology of the urodynamic defect is essential for the treatment policy choice. Therefore, in attempt to find out effective means of differential diagnosis between ureteral obstruction due to cervical cancer relapse and due to postradiation lesion, the authors tried transperitoneal aspiration biopsy with thin needle as a tool of such diagnosis. The biopsy was obtained from 19 females. In 14 of them the obstruction was attributed to recurrent cancer, in 5 to radiotherapy. No errors in the diagnosis were made. Thus, the accuracy of the method reached 100%.

[An improved guide for urethral bougies].

A routine-technique urethral bougienage using an elastic guide in marked urethral strictures is performed practically at random in view of great difficulties of the guide advance through the narrow part of the urethra which is not safe for urethral tissues. An atraumatic guide developed by the authors is radio-opaque. This makes it possible to bring it along the urethra to the bladder under the control of x-ray television and to avoid damage to the tissues. The guide was used in 9 patients with urethral strictures who failed bougienage attempted by conventional methods. Not only the results were positive, but also there were no complications such as urethrorrhagia, false urethral passages and urethral fever.

[The combined treatment of urinary incontinence after adenomectomy].

Treatment was applied in 55 patients with enuresis after removal of adenoma of the prostate. Nonoperative treatment of 46 patients included therapeutic exercises, drug therapy (anti-inflammatory agents and tonics), and physical methods: transurethral direct electrical stimulation of the vesical sphincters (25 patients), transperineal ultrasonic stimulation (21 patients). After nonoperative treatment enuresis was completely cured in 31 patients. Fifteen patients with poor results were subjected to a second course of treatment: a satisfactory result was produced in another 6 patients, an improvement was recorded in 9 patients. Operative treatment was carried out in 9 patients: 4 of them by A. Puigvert's method (satisfactory result in 1, improvement in 1, poor result in 1, acute ischuria in 1) and 5 by a modified Puigvert's operation the techniques of which consisted in forming 2 rectangular grafts from the tunica albuginea of the cavernous bodies of the penis, suturing the medial grafts to one another above the urethra on the midline, and suturing to their bases the lateral grafts (satisfactory results in 4, improvement in 1). Thus, complex treatment of 55 patients for enuresis consequent upon removal of adenoma of the prostate caused a satisfactory result in 42 (76.4%), an improvement in 11 (20%), and a poor result in 2 (3.6%) patients.
