Abstract

The invention relates to medicine, in particular to urology, andrology and surgery. The aim of the invention is to reduce tissue trauma and ease of use by providing maximum anatomical comfort. The phalloendoprosthesis is made of elastic material and consists of the distal, intermediate and proximal parts, where the intermediate part is concave with a section smaller than the distal and proximal parts, and the distal part has transverse annular recesses, and its end is softer than the main part. 9 ill.

Description

The invention relates to the field of medicine, in particular, urology, andrology and surgery.

Known prosthesis (US patent No. 4177805), containing basically reinforced materials, however, they provide the flexibility of the penis in only one vertically plane.

Despite the variety of proposed prosthetic modifications, the surgeon constantly experiences difficulties in selecting an adequate prosthesis for the size of the cavernous body of the penis. If the prosthesis turns out to be somewhat smaller than the cavernous body, then this leads to the displacement of the prostheses in the cavernous bodies during sexual intercourse, reduces the size of the penis and, most importantly, injures the tissues, contributes to the development of inflammation in them and prosthesis.

When prostheses are installed slightly larger than the sizes of the cavernous bodies, the cavernous body is constantly sharply extended, the prosthesis presses on the tissues, disrupts blood circulation, which leads to the development of aseptic inflammation, tissue necrosis and prolapse of the prosthesis.

Also known is a monolithic phalloendoprosthesis, described in Tudor n T. Zouesen C ,, Angelesen H. Practirung des penis - ZbL, Chlr., 1978, 103, 14, 901-910, some of which is made of flexible material. Among such prosthetic constructions, it is the most perfect. Using this prosthesis, it is possible to create a penis of sufficient length and lowered down, which greatly simplifies the problem of hiding the penis in everyday life.

The disadvantage of this prosthesis is that it is monolithic, has a constant proximal part, and this does not allow in each case to choose a prosthesis corresponding in size to the cavernous bodies of the penis, which entails

This is due to its displacement in the proximal direction, in connection with which the insert goes under the lap and the penis loses its ability to bend at its base. Thus, the main advantage of this prosthesis is lost. In addition, the mismatch between the size of the prosthesis and the proximal part of the cavernous body increases the mobility of the prosthesis, its stabilization is impaired, and this increases the possibility of prolapse of the prosthesis. Of the 10 patients operated on using Tudorui-type prostheses, three showed a soft insert displacement, which led to impaired penile mobility, and 3 patients had prolapse of the penis due to impaired stabilization and increased mobility of the prosthesis.

The aim of the present invention is to reduce trauma to tissues and organs and ease of use.

In FIG. 1 shows a phalloendoprosthesis; FIG. 2-9 - stages of the implementation of the method by him / her.

The phalloendoprosthesis is made, for example, of silicone rubber and consists of proximal (1) and distal (3) and intermediate 2. The intermediate part 2 is concave with a section less distal. and proximal parts. The distal part has transverse annular recesses 4, and its end 5 is softer than its main part.

The phalloendoprosthesis is implanted as follows.

Under general anesthesia (for example, Mask anesthesia) or under epidural anesthesia, the foreskin of the penis is shifted to maximal direction. A skin incision 3-4 cm long is made transversely along the dorsum of the hula penis, 0.5-1.0 cm indented from the coronal groove (Fig. 1). The superficial and deep fascia are dissected, the albumen is exposed (Fig. 2 ) The white membrane of the right cavernous body is dissected with a longitudinal section 1.5-2 cm long (Fig. 2). Penis held by

head, enter a thin straight Geghar bougé into the incision of the cavernous body and carefully advance it in the proximal direction until it stops - its cavernous tunnel

the body of the penis, including its leg (Fig. 3). After tunneling of the proximal part of the cavernous body, tunneling of the distal part and insertion of the bougie to the apex of the cavernous body are carried out (Fig. 4). Gradually increasing the diameter of the bougie, expand the tunnel to a diameter of 12-12.5 mm. Using a bouge and a ruler, the length of the formed tunnel is measured, the prosthesis is inserted first into the proximal part as far as it will go, and

then the end of the prosthesis is inserted into the distal part of the cavernous body under the head (Figs. 5, 6). The wound of the tunic sheath is sutured continuously with catgut (Fig. 7). Then, the same operation is performed on the left cavernous body. The skin wound is sutured with a monolithic nylon cap, a circular, slightly pressing bandage is applied

The final arrangement of prostheses in the cavernous bodies is presented in

fig 9

In the postoperative period, a connective tissue capsule is formed around the prostheses with its ingrowth into the existing circular grooves of the prostheses. Etr

makes prostheses motionless in relation to the walls of the capsule and the cavernous bodies of the penis. This ensures the normal functioning of the penis and prevents the prolapse of prostheses
