Scrotal flaps for skin deficit correction after failed hypospadias repair.

Purpose: To analyze the effectiveness of scrotal flaps' use for skin deficit correction in re-operative cases to improve hypospadias' treatment results in children.

Methods: In the Urology Department of the Russian Children's Clinical Hospital (from 2013 to 2019) 46 patients were treated with hypospadias who underwent 3 to 7 failed repairs before being admitted to the clinic. Patients were divided into two groups: Group I - 24 patients with ventral skin deficit and proximal hypospadias; Group II - 22 patients with circumferential skin deficit and mid-shaft hypospadias.

[Ventral penis curvature correction in children with hypospadias].

Objective: Our study aims to improve hypospadias in children by successfully correcting ventral penile curvature.

Materials And Methods: From 2014 to 2018, 424 patients with ventral penile curvature of 15-60 degrees were treated. All patients were divided into 3 groups depending on the form of hypospadias: Group I consists of 303 patients with subcoronal and midshaft hypospadias; Group II - 48 patients with midshaft hypospadias who earlier underwent urethroplasty; Group III - 73 patients with chordee without hypospadias.

[Correction of urethral stenosis after proximal hypospadias repair in children].

Aim: Urethral stenosis is one of the serious complications after proximal hypospadias repair. A variety of techniques has been suggested for its correction, such as urethral dilation using bougies, endoscopic incisions and one- or two-staged urethroplasty with buccal mucosa. The aim of our study was to improve results of urethral stenosis correction in children after multiple proximal hypospadias repairs.

Buried Penis Surgical Correction: Midline Incision Rotation Flaps.

Objective: To improve cosmetic and functional results of buried penis correction in boys using a modified universal surgical approach - Midline Incision Rotation Flaps.

Materials And Methods: We retrospectively analyzed results of 18 patients who underwent buried penis surgical treatment according to the Midline Incision Rotational Flaps technique from 2013 to 2016. The results were assessed by the surgeon 1, 3, 6 months after surgery, then yearly.

[Comparative histological analysis of different materials used for urethroplasty in children with proximal forms of hypospadias: preputial skin vs buccal mucosa].

Aim: Buccal mucosa and preputial skin grafts are used for staged urethroplasty in proximal forms of hypospadias in children. Aim of our study was to carry out a comparative histological analysis of preputial skin and buccal mucosa.

Method: s and materials: Histological analysis of urethral tissue samples from 10 patients with proximal forms of hypospadias was conducted.
