Abstract

Non-transecting anastomotic urethroplasty – is three types of urethroplasty, which are united on the principle resection of bulbar urethra with sparing of corpus spongiosum and antegrade blood flow through it. The article describes the surgical technique of urethroplasty: dorsal strictureplasty by Heineke–Mikulicz; strictureplasty by Mundy; vessel-sparing anastomotic urethroplasty by Jordan. Obligatory conditions of the non-transecting anastomotic urethroplasty are a non traumatic etiology, length of the stricture not more than 1–1.5 cm, and its localization in the proximal bulbar urethra. Strictureplasty by Heineke–Mikulicz is a dorsal longitudinal incision of the urethra on the area of stricture and subsequent suturing the defect transversely. Strictureplasty by Mundy is a dorsal longitudinal urethrotomy, excision of the affected mucosa inside the lumen of the urethra and transversely urethral closure according to Heineke–Mikulicz, s principle. Vessel-sparing anastomotic urethroplasty by Jordan is circular excision of the urethral mucosa without crossing of corpus spongiosum and incoming into it bulbar arteries and thereby preserving the antegrade blood flow through the urethra.

Схема операции стриктуропластики по Heineke–Mikulicz [2]: а – мобилизация бульбозного отдела уретры по дорсальной поверхности; б – дорсальная уретротомия в области стриктуры; в – поперечное ушивание дефекта уретры без иссечения пораженной слизистой

Summary

Introduction

Анастомотическая уретропластика без пересечения спонгиозного тела (хирургическая техника) Анастомотическая уретропластика без пересечения спонгиозного тела – это 3 варианта пластики уретры, объединенные по принципу резекции бульбозного отдела уретры с сохранением спонгиозного тела и антеградного кровотока по нему. В статье описана хирургическая техника операций: дорсальной стриктуропластики по принципу Heineke–Mikulicz; стриктуропластики по Mundy; сосудосберегающей анастомотической уретропластика по Jordan.
