A preemptively planned en bloc resection, including the right kidney and caval thrombus, was performed. VVB and a Pringle maneuver were used to minimize hemorrhage and maintain hemodynamic stability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Surgery was successfully completed without major complications.

The dog's general condition stabilized the following day with no decline in renal function. The histopathologic examination confirmed the diagnosis of RPS.
