PUJ Obstruction /
UPJ Obstruction

Overview

Kidneys filter the blood to remove waste, excess fluid, and maintain electrolyte levels. Renal pelvis connects the kidneys to the ureters, and any obstruction in the renal pelvis is called UPJ obstruction (ureteropelvic junction obstruction). The obstruction can be total or partial that prevents urine to pass through from the kidneys to the ureters, and this can lead to hydronephrosis- the swelling of the kidneys because of urine accumulation.

Here are some causes of obstruction of ureteral junction:

  • Congenital: Congenital ureteropelvic junction obstruction is the most common case, hydronephrosis (enlarged kidney) is detected during ultrasound of pregnant women
  • Kidney stones
  • Previous surgery
  • Abnormal blood vessels
  • Tumor
  • Upper urinary tract swelling

Recovery

Pyeloplasty is a safe and effective ureteropelvic junction obstruction treatment, and the success rate of this surgical procedure is more than 95 percent. Here are some things you can expect after the surgery:

  • Pain medications are given to alleviate pain and discomfort because it is expected that the ureter is swollen for a few days.
  • Scheduled clinic visits to check the status of the patient and the post-operative site.
  • The ureteral stent will be removed after more or less 4 weeks.
  • The urologist may order an ultrasound a few weeks after the surgery to check for hydronephrosis.
