A new method is suggested for the exclusion of intestinal fistulas by the formation of by-pass anastomoses by means of a permanent magnet. The variants of the techniques of magnet by-pass anastomoses are discussed. The results of treatment of 46 children with external intestinal fistulas are shown. With the formation of a by-pass compression anastomosis the mortality rate among children with intestinal fistulas reduced from 31 to 13%.

[A way to improve the quality of compression anastomoses of the urethra in children].

The paper presents the analysis of compression anastomosis establishment in surgical treatment of children with posttraumatic strictures of the posterior urethra. It is noticed that quality of the anastomoses deteriorates with enlargement of the interpolated tissues layer. Anastomosis is suggested to be formed between submucous layers. The new variant was tried in experiment on 9 dogs and in 5 patients with posttraumatic urethral strictures. As a result of more advanced anastomoses the thickness of the interpolated tissues reduced 2-3-fold. The techniques of the above surgery are discussed as well as the advantages of the proposed submucous compression anastomosis in posttraumatic strictures of the posterior urethra.

[The surgical treatment of congenital hydronephrosis in children].

Available are the results of surgical treatment (Andersen-Hynes operation and its modifications) of 85 children with hydronephrosis bor the period 1981-1987. The patients' age ranged from 6 months to 14 years. Anastomotic stenosis occurred in 12% of the procedures as a result of: urethral or pelvic trauma when suturing, wound channels due to the needle perforating puncture, catgut unwanted properties, tissue strain at the anastomosis site, inadequate renal drain. This necessitates modification of the operative technique: surgical manipulations restricted to the operated on pelvic part and pelvic-urethral segment, optical amplification, microsurgical instruments, synthetic suture. An original pyelostoma made of silicon rubber was used in draining. Out of 34 surgical cases, good results were achieved in 31, satisfactory in 3. No complications were recorded.

[Treatment of short urethral strictures in children using magnets].

In 20-35 per cent of short (up to 05 cm) urethral stenosis or cicatricial obliterations of urethra it was found advisable to start the treatment with nonoperative technique. Before 1982 bouginage or tunneling of urethra were commonly used. In 5 out of 6 children the strictures relapsed. Since 1983 when permanent magnets were employed, in 4 out of 5 patients normal urination recovered. 1 child was exposed to preventive 5-months bouginage to ensure constant patency of urethra. Long-term results in all the children satisfied the investigators. But out of 3 magnet-treated children with longer strictures (more than 1 cm) the disease relapsed in 2. It was concluded that in patients with longer stenosis the method was a failure, but in those with short ones the technique was more effective than routine methods. Besides, technical availability, safety and shorter terms of the treatment could also be regarded as the benefits of the aforementioned therapy.
