RU87348U1 - DEVICE FOR TREATMENT OF STRESS CONTINUITY OF URINE IN WOMEN - Google Patents

Abstract

A device for treating stress urinary incontinence in women, which is a set of tools for holding a tape from a prolene mesh and the tape itself 300 mm long and 10 mm wide, characterized in that two fixing ledges are made at a distance of 80 and 110 mm from each edge of the tape from a prolene mesh of a triangular shape at a distance of 30 mm from each other.

Description

The utility model relates to medicine, namely to urogynecology and can be used for surgical treatment of stress urinary incontinence (CHM) in women.

The problem of creating a simple and effective utility model for surgical treatment of heart failure in women remains relevant to date. According to Russian and foreign authors, the number of relapses reaches 30% or more.

A useful model is known, containing a curved elongated shaft with a latch and a handle on the non-working end (US 5112344, 05/12/1992).

However, the known utility model cannot be used effectively for the simultaneous correction of genital prolapse and urinary incontinence.

The closest to the achieved effect is a utility model, which is a set consisting of a tape from a prolene mesh, tools for conducting the tape, which are used in the TVT operation (Ulmsten U, Falconer C, Johnson P, et al. A multi-center study of tention - free vaginal type (TVT) for surgical treatment of stress urinary incontinence. Int Urogynecol J Pelvic Floor Dysfunct. 1998; 9: 210).

However, the known utility model has low efficiency due to insufficiently reliable fixation in the tissues of the tape from the prolene mesh and expensive, which reduces its availability.

The authors propose a highly effective utility model that allows to increase the reliability of fixing the tape from the prolene mesh in the tissues, strengthen support for the middle-third of the urethra and reduce the number of relapses.

The technical result of the claimed utility model is to improve the design, in particular, of the prolene mesh tape, which makes it possible to increase the effectiveness of surgical treatment of SNM in women by increasing the reliability of fixing the tape from the prolene mesh.

The technical result of the claimed utility model is achieved in that at a distance of 80 mm and 110 mm from each edge of the tape, two fixing steps are made of a triangular-shaped prolene mesh at a distance of 30 mm from each other.

The figure shows a schematic representation of a utility model.

The inventive utility model (figure) is a set consisting of a tape 1 of a prolene mesh and tools for holding the tape 1 paraurethrally into the backward-facing space. Tape 1 has a length of 300 mm and a width of 10 mm. On the tape 1 there are fixing ledges 2 made of prolene mesh and having a triangular shape. The fixing ledges 2 are made two on each side of the tape 1 at a distance of 80 mm and 110 mm from each edge of the tape 1 and 30 mm between them. Instruments for carrying out the tape are standard for surgical treatment of CHM in women.

The inventive utility model is used as follows.

In the position for operations on the vagina, under i / v anesthesia, stepping 10 mm from the external opening of the urethra, the anterior wall of the vagina is cut in the middle-third of the urethra with a length of 20 mm. They produce limited mobilization of paraurethral spaces in the acute way on both sides. A conductor probe is inserted into the lumen of the Foley catheter, with which the bladder is deflated deflectively when holding needles with a loop to prevent injury. The needles begin paraurethrally and continue paravesically, perforating the pelvic diaphragm and aponeurosis of the rectus abdominis muscle, leading the needles to suprapubic wounds. After holding the needle, cystourethroscopy is performed to exclude possible perforation of the bladder. Further, without tension, the tape 1 in the form of a loop is installed in the area of the middle-third of the urethra and fixed to paraurethral tissues. Subsequently, the tape 1, sprouting connective tissue, is a reliable support for the middle to third of the urethra. Due to the fixing ledges 2 decreases the mobility of the tape 1 in the tissues, thereby achieving a more reliable fixation.

Clinical example: B. B., with a diagnosis of Stress urinary incontinence, was undergoing treatment in a railway hospital where she underwent surgery using the inventive utility model, namely a tape made of prolene mesh with fixing ledges on it, by applying the latter in as a free loop under the middle third of the urethra. The postoperative period was uneventful, self-urination resumed the day after surgery, the patient kept urine. When examining the patient on the chair, the seams are without features, urine does not leak when strained. B-th was discharged with recovery. Upon examination after 6 months, the patient did not complain of urinary incontinence.

The inventive utility model is applied in 10 women with SNM. After 3 years, all patients were satisfied with the result of the operation and did not show symptoms of incontinence. Visually and palpation implanted tape was not determined. Reliable fixation of the tape in the tissues due to the fixing ledges leads to effective support of the middle-third of the urethra, which leads to a decrease in the number of relapses.

Thus, the claimed utility model is highly effective due to the increased reliability of fixing the tape from the prolene mesh in the tissues, which is achieved by the presence of fixing ledges made on the tape. The prostate in use and affordable cost will ensure high demand of the claimed utility model.
