[Obstructive complications of endoscopic treatment of vesicoureteral reflux in children].

The study was aimed to the selection of patients, in which endoscopic treatment of vesicoureteral reflux (VUR) is contraindicated due to the high risk of the formation of obstructive hydroureteronephrosis (HUN). From June 1991 to December 2011, endoscopic treatment of I-V degree VUR was performed in more than 4,000 children aged 4 months to 17 years. In period of wide use of endoscopic technique, obstructive HUN occurred in average in 1 (0.

[Efficiency of endoscopic treatment of primary vesicoureteral reflux depending on bulking agent].

From June 1991 to December 2011, endoscopic treatment of vesicoureteral reflux (VUR) was performed more than in 4,000 children aged 4 months to 17 years. As bulking agents, teflon paste, DAM +, urodex, and vantris were used. A comparative evaluation of the effectiveness of single endoplasty with various bulking agents in children with I-V degree primary VUR, who had no gross congenital abnormalities in ureterovesical anastomosis, such as paraureteral diverticula, complete duplicated ureter or extravesicalisation of ureter, and not suffered from chronic cystitis, was performed.

[Urinary bladder hemangiomas in children: experience with endoscopic treatment].

Urgent arrest of bleeding is often required in hemangiomas. Endoscopic photocoagulation with Ne YAG-laser was applied in the department of urology of the Central Children's Hospital in Moscow to arrest bleeding in 5 children (2 boys and 3 girls aged 3-12 years) with hemangioma of the bladder in 1998-2009. In 3 cases the tumors were solitary (up to 5 cm), in 2 cases (multiple small 1-3 cm).

[Endoscopic electroexcision of benign urethral tumors in children].

Endoscopic treatment was performed in 17 boys aged 4 months-16 years with benign new growths of the posterior urethra: false polyps (n = 11), fibroepithelial polyps (congenital--4, acquired--1), fetal rabdomyoma of the urethra and urinary bladder (n = 1). Acquired fibroepithelial polyp was detected in a patient who previously had resection and urethral anastomosis for posttraumatic stricture and long-term preventive catheterization. A leading symptom of the disease in 8 patients was infravesical obstruction.

[Valves of the posterior urethra in children].

The paper reports the analysis of 62 cases of posterior urethra valves treated from 1988 to 1993 in the Central Children's Hospital of Russia. The patients' age ranged from 6 months to 14 years. The patients were examined with the use of urethroscopy, urethrography and urodynamic tests providing accurate differential diagnosis of the urethral valves and other infravesical obstructions.

[Evaluation of the effectiveness of vesicoureteral reflux treatment in children by endoscopic implantation of Teflon paste].

The paper assesses the results of treating 193 vesicoureteral refluxes of all forms and degrees in 135 children aged 1.5-14 years by endoscopic submucosal implantation of Teflon paste. The contraindication for surgery is acute urinary infection.
