Laparoscopic Pyeloplasty provides patients with a safe and effective way to perform reconstructive surgery of a narrowing or scarring where the ureter (the tube that drains urine from the kidney to the bladder) attaches to the kidney through a minimally invasive procedure. This operation is used to correct a blockage or narrowing of the ureter where it leaves the kidney. This abnormality is called a ureteropelvic junction (UPJ) obstruction which results in poor and sluggish drainage of urine from the kidney. UPJ obstruction can potentially cause abdominal and flank pain, stones, infection, high blood pressure and deterioration of kidney function. When compared to the conventional open surgical technique, laparoscopic pyeloplasty has resulted in significantly less post-operative pain, a shorter hospital stay, earlier return to work and daily activities, a more favorable cosmetic result and outcomes identical to that of the open procedure.
Laparoscopic pyeloplasty is performed under a general anesthetic. The typical length of the operation is 3-4 hours. The surgery is performed through 3 small (1cm) incisions made in the abdomen. A telescope and small instruments are inserted into the abdomen through these keyhole incisions, which allow the surgeon to repair the blockage/narrowing without having to place his hands into the abdomen.
Ureteropelvic Junction (UPJ) Obstruction
A small plastic tube (called a ureteral stent) is left inside the ureter at the end of the procedure to bridge the pyeloplasty repair and help drain the kidney. This stent will remain in place for 4 weeks and is usually removed in the doctor’s office. A small drain will also be left exiting your flank to drain away any fluid around the kidney and pyeloplasty repair.
