Which procedure involves a connection of the ureters to the skin?

The procedure that involves creating a direct connection of the ureters to the skin is known as ureterocutaneous transplant. This surgical technique is typically performed when there is a need to divert urine from the kidneys to the exterior of the body due to various medical conditions, such as bladder cancer or severe bladder dysfunction. In this procedure, the ureters are brought directly to the surface of the skin, allowing urine to exit the body.

In contrast, ureterosigmoidostomy involves connecting the ureters to the sigmoid colon, allowing urine to be expelled through the rectum, not the skin. The ileal conduit is a type of urinary diversion that uses a segment of the ileum (part of the small intestine) to create a stoma for urine to exit the body, but it does not involve directly connecting the ureters to the skin. Cecostomy is a surgical procedure that creates an opening from the cecum to the abdominal wall for the purpose of colonic drainage, which is unrelated to the ureters.

Focusing on ureterocutaneous transplant highlights its specific role in urinary diversion and how it facilitates the direct drainage of urine through an external stoma.
