Patients with stenosis of the renal pelvic-ureteral junction cause dilatation of the renal pelvis and fluid accumulation, which will not disappear after surgery. The main purpose of the surgery is to keep the dilated renal pelvis and fluid accumulation from further aggravating the renal function.
Stenosis of the renal pelvic-ureteral junction belongs to the more common developmental malformations of the urinary system, and this condition will lead to dilatation of the renal pelvis and accumulation of fluid in the kidneys, which will cause the patient to suffer from lower back pain, recurrent urinary tract infections and other problems.
Surgery involves removal of the stenotic segment, pyeloplasty and ureteral anastomosis. The dilatation of the renal pelvis that has developed prior to the surgery may be reduced after the surgery, but it is difficult to return to normal, so the pelvis will still be dilated and fluid will remain.
After the operation, the patient should go to the hospital for follow-up examinations, and if the dilatation of the renal pelvis continues to worsen, the patient should be treated aggressively.
