Percutaneous drainage of the gallbladder and the percutaneous placement of nephrostomy tubes to divert urine flow may be indicated with certain neoplastic processes. Both ultrasound and fluoroscopic guidance have been used to place these tubes (Morgan and Adam 2001; Covey and Brown 2006; Saad et al. 2009; Uppot 2009). These techniques may be useful as temporary palliative measures to stabilize patients prior to a definitive surgery.

Minimally invasive placement of nephrostomy and cholecystostomy tubes is being performed in veterinary clinics, but reports are lacking. In a canine cadaver study, pigtail catheters were placed in gallbladders using both ultrasound guidance and laparoscopic guidance, and the two techniques were compared (Murphy et al. 2007). The laparoscopic‐guided technique was found to be significantly more likely to result in successful placement of the pigtail catheter (Murphy et al. 2007). Percutaneous biliary drainage has been shown to be safe and effective in humans (van Delden and Laméris 2008), and further investigation of these procedures in veterinary cases is necessary.
