Final answer:
Acucise endopyelotomy is a surgical procedure used to correct a blockage at the ureteropelvic junction, which could be impaired due to narrowing, not the presence of kidney stones themselves. It allows urine to flow from the kidney to the bladder by widening the restricted junction.
Step-by-step explanation:
Acucise endopyelotomy is a surgical procedure used to treat a blockage in the ureteropelvic junction. This condition is often caused by kidney stones, which are solid crystals that form from minerals in urine within the kidney. When a kidney stone grows large enough, it can obstruct the ureter, leading to pain, decreased kidney function, or kidney damage.
However, an Acucise endopyelotomy is not performed to treat kidney stones directly. Instead, it is utilized when the blockage at the ureteropelvic junction (the connection between the ureter and the part of the kidney that collects urine) is caused by a narrowing of this passage, not by the stone itself. By making a precise incision in the narrowed area, this procedure helps to widen the junction, allowing urine to flow more freely from the kidney to the bladder.
If a stone itself is causing the blockage, options such as lithotripsy (using high-intensity ultrasound pulses to break the stone into smaller pieces) or the insertion of a stent to expand the ureter might be considered. In more severe cases, a larger stone may be removed surgically, but this would not be referred to as an Acucise endopyelotomy.
