"Ureters" Natural Recordings by Native Speakers
The ureters are a pair of narrow tubes that transport urine from the kidneys to the bladder. They are roughly 10-12 inches (25-30 cm) long in adults and are located in the pelvis and abdominal cavity. The function of the ureters is to:
1. Collect urine from the kidneys through the calyces and renal pelvis.
2. Transport the urine to the bladder through muscular contractions and gravity.
3. Keep the urine flowing smoothly by peristalsis (wavelike muscle contractions).
The ureters are tube-like structures with a diameter of about 2-3 millimeters (0.08-0.12 inches). They are lined with smooth muscle and mucous membranes, which help to prevent the formation of kidney stones and infections. The walls of the ureters also have a layer of connective tissue that provides support and protects the surrounding structures.
Ureteroscopic refers to a medical procedure that uses a ureteroscope, a thin, flexible or rigid endoscope, to visually examine and treat abnormalities of the ureter. The ureteroscope is inserted through a small incision in the bladder or a natural opening, and is navigated through the ureter to inspect the interior of the ureter and remove kidney stones or other blockages.
Ureterostomy is a type of surgical procedure in which a stoma is created in the bladder (an opening in the abdomen to allow urine to drain) and the ureters (the tubes that carry urine from the kidneys to the bladder) are diverted back to this area, often due to a blockage or obstruction in the normal urinary tract.<br><br>A ureterostomy is usually performed to bypass a blockage or obstruction in the ureter that is located lower than the kidney, making it impossible for urine to drain normally. This condition can be caused by external compression (e.g. a kidney stone, cancer), internal strictures (narrowing of the ureter), or other abnormalities.<br><br>There are several different types of ureterostomies, including:<br><br> Bricker procedure (also known as ileal conduit): This involves creating a new path for urine to drain from the kidney to the bladder using a portion of the intestine (ileum).<br> Boari flap: This involves creating a flap of tissue in the bladder to receive the ureter.<br> Ureteral reimplantation: This involves repositioning the ureter and reconnecting it to the bladder.<br><br>The main goals of a ureterostomy are to:<br><br> Allow urine to drain from the kidney to the bladder (or outside of the body, in the case of a percutaneous nephrostomy tube)<br> Avoid infection and kidney damage (which can occur if urine becomes stagnant behind a blockage)<br> Protect the kidney from further damage<br> Improve the quality of life for the individual by allowing them to urinate normally<br><br>Overall, ureterostomy can be an effective way to manage certain types of blockages in the urinary tract and improve urinary function, especially in patients with no viable alternative options.
Ureterotomy is a medical procedure, specifically a surgical incision made into the ureter, typically to relieve blockage or obstruction of the ureter.
