Currently, the method of ureteral stricture reconstruction is receiving much attention and is being applied by hospitals. There are many methods of ureteral reconstruction that can endoscopically dilate the narrowed segment and then connect the two ureteral segments together, or connect the ureter directly to the kidney or to the bladder.

Post-vein ureteropathy is an abnormal path of the ureter that causes compression of the inferior vena cava, leading to hydronephrosis. If left untreated, the disease will cause serious effects on kidney function. Therefore, the effective treatment method and the first choice of doctors is endoscopic surgery to create a post-vein ureteroplasty.

The cause of renal pelvis-ureteral junction narrowing can be due to anatomical or functional reasons that cause narrowing of the junction, obstructing the flow of urine from the renal pelvis to the ureter, leading to hydronephrosis. To improve this condition, doctors will use laparoscopic surgery to reconstruct the narrowed junction, helping urine to flow normally and avoiding risks affecting the kidneys.

Epidural anesthesia is an anesthetic method commonly used in hysterectomy and oophorectomy with ureteroplasty to inhibit nerve conduction in the area innervated by the nerve roots. When prescribing epidural anesthesia in this type of surgery, it is necessary to pay attention to some contraindications and possible complications for timely treatment.
