Ureteral Pelvic Junction Obstruction
Surgery to correct the blockage allows urine to flow normally. Open (invasive) surgery is usually performed in infants. Adults may be treated with less-invasive procedures. These procedures involve much smaller surgical cuts than open surgery, and may include:
- Endoscopic (retrograde) technique does not require a surgical cut on the skin. Instead, a small instrument is placed into the urethra and allows the surgeon to open the blockage from the inside.
- Percutaneous (antegrade) technique involves a small surgical cut on the side of the body between the ribs and the hip.
- Pyeloplasty removes scar tissue from the blocked area and connects the healthy part of the kidney to the healthy ureter.
- Recently, laparoscopy and robotic surgery has been used to treat UPJ obstruction in children and adults for many patients has become first line treatment.
A tube called a stent may be placed to drain urine from the kidney until the patient heals. A nephrostomy tube, which is placed in the patient's side to drain urine, may also be needed for a short time after the surgery. This type of tube may also used to treat severe infections before surgery.
