| A small amount of urine drips constantly from your kidneys to your bladder through tubes called ureters. |
| Patients with other abnormalities such as ectopic ureters and diverticulae can also present with incontinence. |
| At the center of the concave side, where the ureters and veins issue and arterial vessels and nerves usually enter, is the hilus. |
| The urine is passed to the bladder through ureters from each kidney in peristaltic waves. |
| This technique involves placing an ureteroscope into the urethra the bladder and then finally up the narrow ureters to engage a ureteral stone and break it or remove it. |
| The ureteral catheters enable the surgeon and assistant to see and palpate the ureters during the procedure. |
