History

This is an ultrasound-guided endoscopic diode laser ablation (UGELAB) of a transitional cell carcinoma in the uirinary bladder of a 10-year-old FS Beagle. There were many polyps in the trigone and urethra that were ablated as well. Rosie is doing well 12 months post UGELAB. This procedure was performed by Dr Dean Cerf (Laser/scope) and Dr Eric Lindquist at Dr. Cerf's facility of Ridgewood Veterinary Hospital, Ridgewood, NJ, USA. The original abstract for this procedure was presented at ACVIM (Seattle)and ECVIM (Budapest) 2007 and will be also presented for a full hour lecture at ACVIM June 5, 2008 in San Antonio, Tx.

Laser ablation in a tight spot near the right ureter papilla that is obstructed by the tumor. Even though the ureter could not be liberated directly due to its this walls, the mission of the procedure was to free the ureter obstruction by liberating as much tumor as possible around the papilla. Hopefully this would lead to less impingement and consequent liberation of the obstructed ureter.
7 days post UGELAB with residual tumor, approximately 40% of the presenting mass, but no hydroureter after slough of the HTNL and resultant lack of impingement.
