Urethral stent placement is a technique used for obstructive urinary tract diseases. Most commonly this technique is used in cases of cancer of the lower urinary tract. It buys some extra time in cases of terminal cancer of the urinary tract. It also increases survival time of patients with cancer in the urethra only. These cancers are usually not resectable and no effective treatment is available. Urethral stents can lead to temporary incontinence in female dogs. Its benefits usually last for 2-4 months, and occasionally much longer.
