in situ ureterostomy

A ureterotomy is a measure of urine in the upper urinary tract on the side of the drainage surgery. According to different lesions, surgical indications and follow-up surgery after stoma, ureterostomy is roughly divided into two types: 1 ureteroplasty; 2 end ureterocutaneous ostomy. Curing disease: Indication Intraurethral ureterotomy is a temporary urinary diversion surgery, often used as part of other ureteral procedures, such as ureteral anastomosis, ureteral plastic surgery, ureterotomy and stone removal. At the end of the operation, the ureter is placed in a catheter stoma. The catheter has the dual function of draining urine and support. In addition, temporary urine drainage, such as bladder ureterostomy, may be performed as a temporary urinary tract for the treatment of acute urinary tract obstruction. In recent years, due to the wide application of double "J" shaped tubes, which replace the ureteral in situ stoma, it is rarely used at present. Preoperative preparation 1, if there is imbalance of water and electrolyte balance, vitamin deficiency, severe anemia, etc., should be treated first. 2. For those who have not had the bladder removed, insert a catheter to empty the urine in the bladder. Surgical procedure The ureteral in situ ostomy is actually used to drain the urinary flow. The ureter does not change its original position, and does not interrupt its continuity. It is beneficial for the early healing of the wound in the ureteral surgery area and plays a role in stenting. In renal pelvic ureteral surgery, the ureteral catheter tip can be inserted into the renal pelvis through a surgical incision (plasty incision), and then a thicker needle is used as a puncture to lead the catheter a few centimeters below the anastomosis of the angioplasty. The tail can also be anastomosed. Insert the ureter underneath and puncture it through the puncture. Of course, after the anastomosis is completed, the catheter can be inserted into the renal pelvis through the anastomosis through the puncture mouth, but the puncture mouth can not be cut by knife cutting or scissors, so as to avoid the hole being too large and leaking urine. The catheter can be sutured with a silicone tube of appropriate caliber, and a needle can be sutured at the wall of the ureter with a absorbable fine wire (not penetrating the wall), and the catheter is tied and fixed to prevent the catheter from slipping off. A needle is fixed to the skin or subcutaneous fascia at the extracorporeal of the catheter. The catheter has a small response to the tissue and can be left for more than a few weeks. It can absorb the fine suture and fix the suture without hindering the removal of the catheter. Ankle ureter or ureteral ureteral surgery, the catheter can also be inserted from the bladder up to a few centimeters above the ureteral surgical area, the tail end is introduced into the bladder outside and outside the body through a bladder incision or another puncture, the two are also fixed suture, the bladder is made another Oral surgery.
