Abstract
None:
A flexible suction ureteral access sheath (FS-UAS) is not essential for every endoscopic renal stone treatment. To date, endoscopic combined intrarenal surgery (ECIRS) is the most efficient approach for treating any renal stone. Rigorous randomized controlled trials comparing retrograde intrarenal surgery with an FS-UAS versus ECIRS should be performed before superiority or even equivalence can be claimed.

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.
