Physician Responsibility
In this procedure, the surgeon inserts an endoscope through a previously established opening between the collecting system of the kidney and the exterior of the body (skin) or opening between the renal pelvis to the skin to examine the kidney, renal pelvis, and ureter. First the surgeon disconnects the external urinary drainage bag from the nephrostomy or pyelostomy tube. A guidewire is then moved forward through the nephrostomy tube and nephrostomy tube is then pulled out over the wire. The surgeon may use some surgical instruments to widen the opening passageway. Once pathway is widened, the surgeon inserts an endoscope, which is a small, flexible tube with a fastened optical system, into the kidney through an established nephrostomy or pyelostomy tract to analyze the interior structures of the renal collecting system. For better visual perception, the physician may use sterile saline solution into the area of the renal collecting system. The physician may instill some other therapeutic solutions into the kidney or contrast material may be used for x–ray photography of the ureter and renal pelvis. Once examination is completed, the surgeon withdraws all the instruments, replaces the tubes, and reconnects the external urinary drainage bag to the tubes for temporary urine flow.
