Urea is also called carbamide. It is an organic chemical compound, which essentially is the waste produced when the body metabolizes protein. It is a compound not only produced by humans but also by many other mammals. It is manufactured in the liver, by broken down protein or amino acids, and ammonia, the kidneys transfer urea from the blood to the urine.

Ureteral catheter is a routine medical procedure that has both diagnostic and therapeutic purposes. It is also used for drainage and retrograde pyelogram in pediatric patients. Urethral catheterization is done with a balloon tip foley catheter of varying sizes.

Ureteroscopic biopsy forceps are designed to pass easily through flexible ureteroscope in tortuous anatomy. The larger jaw capacity maximizes biopsy volume. The long, deflectable shaft enables access into upper urinary tract and renal pelvis. Its scissors-grip handle provides more force to the cutting surface.

Ureteral Access Sheath comprises a sheath assembly having a main lumen and one or more secondary lumens. Ureteral access sheath provides protection against elevated renal pressures during routine flexible ureteroscope stone manipulation.
