ureteral surgery

The ureter is a slender tube that connects the kidney to the bladder. Ureteral diseases can cause self-harm, such as stones, tumors, congenital malformations, etc., but the important problem is affecting the function of the kidney, which may endanger the whole body or the patient's life. Today, due to the development of science and technology, ureteral diseases, whether primary or secondary, have made great progress in diagnosis and treatment, and some areas have undergone conceptual changes. Treatment of diseases: preoperative preparation There is no special preparation before ureteral surgery. Generally, the anesthesia method and the surgical site are routinely prepared. The important problem is to determine the preoperative diagnosis and the surgical procedure to be performed. If there is dilatation and urinary infection above the operating area, consider whether temporary urinary diversion is needed depending on the situation, minimize contaminated urine through the operating area, and allow the ureter in the operating area to have a rest opportunity to facilitate wound healing. . Drainage method: complicated operation of renal ostomy at the same time, general surgery is feasible in the ureteral stent drainage, that is, the end of the ureteral incision into the double J tube to the renal pelvis, the tail end from the ureteral incision into the bladder. It is convenient for urine to flow into the bladder through the catheter, and the catheter has a supporting effect. At the same time as such internal drainage support, most of the renal ostomy is not required. In congenital malformations, such as pyeloplasty, although the kidney only has water expansion and no infection, it is only necessary to set a double J tube. Due to the widespread use of double J intraluminal drainage, most of them have no need for extracorporeal drainage, and there are few opportunities for renal stoma.
