[Appendicovesicostomy for controlled bypass of urine in children].

Catheterization through appendicovesicostomy (AVS) proposed Mitrofanoff in 1980 is an alternative of periodic catheterization of the urinary bladder via urethra. AVS was used in 30 children (21 boys and 9 girls). Appendix with intact mesentery was cut off the caecum and placed between the urinary bladder or artificial urinary bladder and the skin in the umbilical area.

[Creation of artificial urinary bladder in children].

In children creation of artificial urinary bladder using intestinal segments was made in the absent or reduced reservoir function of the bladder. From 1990 to 1998 enterocystoplasty was performed in 30 boys and 6 girls. 15 of them have undergone colocystoplasty, 21--ileocystoplasty with detubulized segment.

[Urological complications in children with myelodysplasia].

A great deal of methods were used to evaluate the urinary tract in patients with myelodysplasia; however, the authors failed to find an informative and easy-to-use diagnostic approach. In the authors' opinion, a simple, available, non-invasive, and safe screening that includes ultrasonography of the bladder and kidneys before and after attempted urination, visualization of urination, squeezing-out test, and general urinalysis should form a basis for diagnosis. The pattern of urination, enuresis, urinary tract infection, obstructive uropathies, the volume of residual urine, the thickness of the detrusor urinae are the basic parameters identified at primary diagnosis.

[The urological screening of children with myelodysplasia].

All children with myelodysplasia have urological diseases. Nevertheless, errors in urological policy and diagnosis are made just at the first stage of a study, by leading to inadequate treatment, progressive obstructive complications, chronic renal failure. The authors propose a urological screening, simple, accessible, and safe tests, which may evaluate the urinary system, determine the expediency and urgency of further examination during early management of children with myelodysplasia.

[Late complications after surgery for high congenital intestinal obstruction in children].

The work analyses the experience in examination and treatment of 31 patients with late-term complications after operations for various types of acute and chronic high congenital ileus. Five groups of children were set apart according to the character and anatomical cause of the complication. The characteristics of late-term complications, their clinical manifestations, and methods of repeated surgical interventions are given.

[Long-term results of treatment of children with severe congenital intestinal obstruction].

A total of 295 children were operated on for severe ileus. The late outcomes of treating 88 children were studied for some months to 18 years. The assessment of the therapy results, the detection of causes of complications and the determination of the functional status were made by using a complex of study methods.

[Duodenal function in some diseases of upper abdominal organs].

Eighty-five children with surgical parasurgical and pediatric abnormalities of upper abdominal organs were studied. In addition to the routine procedures, the authors used the following: endoscopic stepwise manometry, electromyography, polarography, pH-metry. In some chronic pediatric diseases, manometric, polarographic, electromyographic changes were found to correlate with the similar ones in surgical abnormalities.
