Abstract

The invention discloses a tissue engineering urethral stent and a preparation process thereof, and relates to the technical field of polymer materials. Specifically, the preparation process can produce tissue engineering urethral stents suitable for different individuals, and the preparation process is beneficial to large-scale batches Production. Secondly, the tissue engineering urethral scaffold prepared by this preparation process has good biocompatibility, biodegradability and biomechanical properties, and its microporous structure can ensure the adhesion and proliferation of seed cells, so that the tissue engineering urethral scaffold can carry enough A large number of seed cells are suitable for different forms of urethral injury, especially long-term urethral injury repair.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a tissue engineering urethral support and a preparation process thereof. Background technique

[0002] Urethral stenting has been greatly developed in recent years. At present, the commonly used clinical method is to place a tissue engineered urethral stent at the stricture of the urethra to expand the stricture or obstruction of the urethra. This stent is made of stainless steel, synthetic fiber silica gel or nickel-titanium alloy. It can be placed in the stricture of the urethra through the cystoscope to expand the narrow and closed posterior urethra. After recovery of voiding function.

[0003] Urethral tissue damage and functional loss in children caused by factors such as trauma, tumor, and surgery are common diseases of the urinary system, and the search for ideal repair materials for urethral defects has always been the focus of research.
