AI Technical Summary
Technical Problem
After prostatectomy, the sutures connecting the urethra and bladder can shorten the urethra, causing overstretching of the bladder and urethra, which may lead to urinary incontinence.
Method used
Using specific weaving molds and weaving yarns, a multi-lobed urethral bladder support is woven. The diamond-shaped structure supports the urethra and bladder, limiting excessive stretching. The weaving yarns do not knot, forming a single integrated structure.
Benefits of technology
It effectively reduces the occurrence of urinary incontinence. The urethral bladder stent is more stably connected to the bladder, adapts to the shape of the bladder, and reduces excessive stretching of the urethra and bladder.
