Yes, a little cmos battery. I have to take one out myself to reset the bios! You can download the manual from acer I think to locate it. It does invole carefully removing some things.
Transitional cell cancer of the renal pelvis and ureter is a disease in which malignant (cancer) cells form in the renal pelvis and ureter. The renal pelvis is the top part of the ureter. The ureter is a long tube that connects the kidney to the bladder. There are two kidneys, one on each side of the backbone, above the waist. The kidneys of an adult are about 5 inches long and 3 inches wide and are shaped like a kidney bean.
What is the size of the renal pelvis? I have a 1.6 cm dense stone per CT on 10/21. Dense stone within the right collecting system 1.6 cm in the renal pelvis and a 2nd stone 1.1 cm in the mid kindey medially. I have had large stones before, but always in the kidney itself. The largest was 2.5 cm by 4.5 cm. It took 10 hours of surgery over 3 days to remove. Is the one in the renal pelvis different than one inside the kidney?
