Principles of the Procedure

This is performed to re-configure a developmentally abnormal non-draining kidney (at the pelvi-ureteric junction) to a normal, freely draining system. Via 3-4 keyhole incisions, the abnormal pelvi-ureteric junction is divided, and then reconstructed laparoscopically to resemble a normal kidney drainage system. A temporary, internal ureteric stent is placed to facilitate healing and subsequently removed following discharge.


Pre-Operative Preparation

You will be admitted on the same day of the procedure. You will need to have a recent urine test (within 2 weeks if the surgery) to ensure that you do not have a urine infection. No other specific preparation is needed apart from fasting about 6 hours prior to the surgery. You should continue to take your usual medications unless directed otherwise by your Urologist or his anaesthetist. Please inform us if you are taking any anticoagulant (blood thinning) medication.


Expected Post-Operative Recovery

Following the surgery, you will wake up with a catheter in your bladder and a thin drainage tube through one of the skin incisions. These are generally removed sequentially the day following your operation. Most patients go home on either day 1 or 2 after the operation. The internal ureteric stent will be booked to be removed about 6 weeks following your operation. Some blood staining of the urine can occur after you go home secondary to the surgery and the presence of the ureteric stent. This almost always settles by keeping your oral intake of fluids up.
