[The surgical treatment of vesicoureteral reflux in kidney duplication in children].

The examination of 41 patients with a complete renal duplication and vesicoureteral reflux (VUR) into 57 ureters has shown a direct dependence of morphological immaturity of the parenchyma of the double kidney segment and functional insufficiency of the obturative apparatus of the ostium of the corresponding ureter on the degree of its dislocation corresponding to the normal localization on the inner surface of the urinary bladder. For patients with marked lateral position of the main ostium of the organ saving operations are senseless because of high degree of VUR and deep dysplasia of the renal tissue. In cases with moderate lateralization of the ureter ostium it is expedient to fulfil such antireflux interventions as Lich-Gregoir operations in a "single block" or the endoscopic correction of the ostium with a synthetic medical siloxan rubber or polyacrylamide gel "Interfall".

[The treatment of vesicoureteral reflux in children].

The authors summed up the 9 years-long experiences with treatment of 2588 children with vesicoureteral reflux. Conservative methods were successful in treatment of 74% of the patients. Of great importance were antibacterial therapy and treatment of the urinary bladder. Surgical interventions were fulfilled in 26% of the patients. Good effects were noted after Lich-Gregoir, Cowen operations, reimplantation of the ureter in 91.4%, 100% and 94.7% of the patients correspondingly.

[Reconstructive-plastic surgery in bladder exstrophy].

Among 234 children with exstrophy of the urinary bladder 112 were subjected to reconstructive-plastic operation after G. A. Pair. A good result was produced in 71 cases. In 27 children a satisfactory result was attained only after repeated operations. Reconstructive-plastic interventions had no positive effect in 14 children. By means of electrophysiological and morphological methods three degrees of underdevelopment of the muscular coat of an urinary bladder affected by exstrophy were distinguished. In I degree plastics of the bladder with local tissues is indicated, in II degree the indications are relative, in III degree a plastic operation is not indicated. Choice of the operative method on basis of the morphofunctional condition of the bladder with exstrophy, the use of microsurgical techniques, the formation of a closed pelvic ring, and antireflux operations on the ureters improve the immediate and late-term results of reconstructive-restorative surgical interventions.

[Surgical treatment of complete epispadias in children].

The operative treatment was used in 46 children with total epispadia. In 37 patients operations were made by the Derzhavin method (in eight of them it was one-step plasty of the ureter and penis with local tissues), in 9 patients the operations were made after Savostitski--Young. Long-term results were observed in 38 patients. Good long-term results were obtained in 25 patients (22 following the Derzhavin operation, 3 following the Savostitski--Young operations). The Derzhavin operation is considered to give better results when performed at the age of 6-7 years.

[Combined injuries of the the pelvic bones and urethral canal in children].

Associated injuries of pelvic bones and urethra were observed in 50 children. The clinical picture, diagnosis and methods of treatment are described with special reference to time gone after trauma. The most effective method of treatment of ruptured urethra is thought to be putting the primary suture.

[Early surgical complications of corrective operations in congenital hydronephrosis in children].

The analysis of immediate results of 271 correcting operations for congenital hydronephrosis in children has shown that the operations may be followed by such complications at the early postoperative period as aggravation of pyelonephritis (10 patients), urinal fistulas (8 patients), urinary leakage (4 patients), paraureteral abscesses (3 cases) as well as postoperative bleedings (5 cases) and suppuration of the operative wound (4 cases). The exact performance of plastic operations according to the elaborated method, strict observation of indications and contraindications, complex therapy in the postoperative period were found to reduce the amount of complications.

[Ureterocele in children].

Ectopic ureterocele associated with double kidney and ureter was observed in 95 children and orthotopic ureterocele in 9 children. Most of them were the girls (91 of 104). All the children were operated upon (135 operations). The results were studied in 78 children within the terms from 1 to 10 years. Useful practical recommendations are given.

[Kidney injury in hydronephrosis in children].

Within the 10 years' period, from 1968 to 1977, 8 children were renal trauma in hydronephrosis were operated upon in the Children's Surgery Clinic in LPMI. 7 patients underwent nephrectomy and one--the plasty of the pyeloureteral segment. The surgical intervention carried out immediately after trauma prevents the occurrence of complications and, sometimes, helps to preserve the kidney. The immediate and late results of the surgical treatment are good, which proves the necessity of an urgent examination and active surgical tactics in case of injury to the kidney in hydronephrosis in children.

[Inferior heminephrectomy in children].

For the recent 15 years 286 children with surgical diseases of double kidney have been under observation in the Clinic of Children Surgery of the Leningrad Pediatric Medical Institute. In 62 of them the inferior major segment of the organ was injured. In 34 cases the loss of the functional capacity of the inferior segment and atrophy of its parenchyma were revealed which served as an indication for inferior heminephrectomy. The vesicouriteral reflux into the main ureter (21 children) or both ureters (3 children) was found to be the most frequent cause of the injury of the inferior segment of the kidney. The subcapsular inferior heminephrectomy in children may be technically fulfilled and does not make problems in the separate blood supply of the segments. It is not expedient to leave a very small accessory segment of the kidney. The inferior heminephrectomy performed after strict indications gives favourable remote results.
