[Histological study of urethral plate: a search of the best material for surgical treatment of hypospadias in children].

Aim: to study the microstructure of the urethral plate in patients with a proximal form of hypospadias to justify the use of tissues from the ventral penile surface when creating an artificial urethra.

Materials And Methods: A histological study of surgical specimens from 10 patients with proximal hypospadias was carried out. The urethral plate, a strip of tissue from the ectopic external urethral orifice located in the penoscrotal angle, to the coronary sulcus, was completely excised and processed by various techniques.

[Modification of two-stage technique of bracka with preservation and tubularization of the urethral plate for repair of proximal hypospadias].

Introduction: Surgical treatment of proximal hypospadias is associated with a number of difficulties and unsuccessful repeated interventions. The changing approaches to the treatment of hypospadias with the revision of the attitude to urethral plate provide new opportunities in resolving this problem.

Aim: to improve the results of surgical correction of hypospadias by creating "artificial" urethra that is very close to a native one in its functional qualities.

[Uretero-ureteral anastomosis (ureteropyeloanasto-mosis) for the duplicated upper urinary tract in children].

Introduction: The duplex kidney is one of the most common congenital abnormalities of the urinary tract, and various surgical procedures exist for the management of this condition. Depending on the surgeon preferences, patients with duplex kidney may undergo heminephrectomy with ureterectomy using open or laparoscopic approach, uretero-cysto-anastomosis of the ectopic ureter or two ureters in a single block. Recently, there have been reports of inter-ureter anastomoses.

[Laparoscopic heminephrureterectomy for duplex kidney in children].

Introduction: Duplication of the upper urinary tract is one of the most common congenital urological anomalies. In patients with critically decreased or lost function of one of the renal segments, heminephrureterectomy is usually the treatment of choice. Until recently, this was an open surgery; in cases of complete removal of the ureter, an additional incision in the iliac region was required.
