Pneumovesicoscopic ureteral reimplantation with intravesical tailoring of obstructive megaureter in pediatric patient.

Introduction: According to available data, there are only few articles describing pneumovesicoscopic (PNV) ureteral reimplantation (UR) for obstructive megaureter without tailoring and with ex vivo tailoring in children.

An Objective: To present our experience of the PNV UR using intravesical ureteral tailoring for symptomatic primary obstructive megaureter in children.

Study Design: Between 2014 and 2020, 42 patients (mean age: 3.

[The opportunities of pneumovesicoscopic approach for correction of disorders of vesicoureteral junction in children].

Background: pneumovesicoscopic approach gives new possibilities for endovideosurgical correction of congenital ureteral and bladder pathology.

Aim: To increase the efficiency of ureteral reimplantation in patients with vesicoureteral reflux (VUR), obstructive megaureter and bladder pathology by using pneumovesicoscopic access.

Materials And Methods: For the period 2014 - 2020 a total of 52 children aged from 10 months up to 15 years (median 2.

[Balanoplasty in accordance with the normal anatomy--the key to successful correction of hypospadias].

The features of the normal anatomy of the balanus and distal urethra were evaluated. It was found that there is a physiological mechanism of stretching of distal urethra during urination owing to the scaphoid fossa, bridle and hippocrepiform-located corpus spongiosum of balanus. Based on these data, modified balanoplasty was proposed, which consisted in mobilization and increase the length of corpus spongiosum of wings of balanus by longitudinal incisions, followed by suturing wings of balanus with separate inside sutures on a short distance not above 3-5 mm and their dipping at a depth not above 1-2 mm.

[The choice of method of urethroplasty in patients with distal and middle hypospadias].

Retrospective analysis of results of the most frequently used methods of urethroplasty: urethroplasty using tubularized dissected urethral area (TIP), urethroplasty using tubularized dissected urethral area with inset the free flap of the foreskin (GTIP) and Mathieu surgery in patients with coronary, distal and middle hypospadias (in primary and recurrent surgery), was performed. From 2005 to 2010, 300 patients aged 7 months to 19 years underwent the surgery. There were no early postoperative complications in any patient, with the exception of early accidental removal of the catheter in 4 patients.
