Sequela of ureteral bladder replantation

The sequelae of ureter and bladder replantation are mainly in two aspects: First, the anti-reflux mechanism is not well done. In this case, the urine of the bladder is easy to reflux to the ureter and renal pelvis, so it is easy to form the expansion of the ureter and renal pelvis. There is infected urine in the bladder, which may flow back to the kidney and cause pyelonephritis. This is a situation. 2. When replanting the bladder and ureter, it is too long to sneak under the mucosa, or the suture is too tight when performing surgery, and the embedding is too deep. This will cause urine from the ureter to enter the bladder, showing new stricture, which will also cause the upper end of the ureter to expand and the renal pelvis to expand. If it is serious, the expansion progress will be much greater than the reflux. Therefore, when performing ureterovesical replantation, it is very important to ensure that there is a certain stealth area and that the ureter enters the bladder smoothly. Normally, when performing ureterovesical replantation, a ureteral stent tube will be supported inside to prevent the ureter from being too tight. This requires the doctor to strictly control the scale during the operation to prevent the sequelae after ureterovesical replantation.
