Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evaluating the effectiveness and safety of neovaginoplasty using photoinduced-imine-crosslink hydrogel in patients with MRKH syndrome by comparing the differences in the degree of squamous epithelialization, vaginal length and width, and sexual life quality.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized controlled trial. Patients meeting the inclusion criteria will be enrolled in this study: 1)Diagnosed with MRKH syndrome; 2)Without previous treatments; 3)Age: 18-35 years old; 4)Voluntary agreement to participate in the study, sign the informed consent form, and demonstrate good compliance with follow-up.

A centralized block randomization will be used to randomly assign patients to ensure that there will be an equal number of patients (1:1) in the hydrogel group and control group. The sample size is 20.

Under general anesthesia and catheterized bladder, the patient was in the lithotomy position. In the connective tissue plane between the bladder and rectum, the vestiges of the müllerian ducts were identified. With the index finger in the rectum as a direction and protection, Hegar's dilators of increasing size (4.5-10) were pushed through the dimples gently. After that, a double-barreled canal appeared. Then, the raphe between the canals was incised. The neovagina was created. According to the randomization, a vaginal mold spreaded with hydrogel or not was placed. The patients were suggested to wear the vaginal mold continuously over the following 6 months. After that, they were allowed to have the first sexual intercourse. Otherwise, the mold wearing time was 1 h daily, until they had sexual activity at least twice a week.

The primary endpoint is the degree of vaginal squamous epithelialization 1 month, 3 months, 6 months after surgery. The secondary endpoints include neovaginal length and width, sexual life quality, and surgical complications.

Arm 1

After neovaginoplasty, a vaginal mold spreaded with photoinduced-imine-crosslink hydrogel was placed in the neovagina.

Group Type EXPERIMENTAL

Intervention Type PROCEDURE

Under general anesthesia and catheterized bladder, the patient was in the lithotomy position. In the connective tissue plane between the bladder and rectum, the vestiges of the müllerian ducts were identified. With the index finger in the rectum as a direction and protection, Hegar's dilators of increasing size (4.5-10) were pushed through the dimples gently. After that, a double-barreled canal appeared.

The patients were suggested to wear the vaginal mold continuously over the following 6 months. After that, they were allowed to have the first sexual intercourse. Otherwise, the mold wearing time was 1 h daily, until they had sexual activity at least twice a week.

Arm 2

After neovaginoplasty, a vaginal mold was placed in the neovagina directly without anything spreaded.

Group Type OTHER
