A new era in the early treatment of dioctophymosis - The first laparoscopic nephrotomy without ischemia in a dog.

The parasite Dioctophyme renale is a nematode that infects carnivores and often causes total and irreversible destruction of renal tissue. In cases of early diagnosis, nephrotomy is an alternative for renal preservation. This report describes the first laparoscopic nephrotomy performed without ischemia in the treatment of a female dog with renal dioctophymosis, using an ultrasonic scalpel for hemorrhage control. The technique stood out for its precision in simultaneous renal parenchyma incision and coagulation, eliminating the need for temporary blood flow interruption to the organ. It allowed the removal of a 32 cm D. renale from inside the kidney. This approach minimized the risks associated with ischemia-reperfusion injury, proving particularly advantageous in cases with partial preservation of renal parenchyma. Postoperatively, the patient exhibited a reduction in the size of the parasitized kidney and normalization of urinary parameters in urinalysis and blood biochemistry, confirming the technique's success. The use of the ultrasonic scalpel proved safe, efficient, and promising as a tool in the minimally invasive surgical management of renal diseases. This technique represents a significant advancement in the treatment of dioctophymosis with renal preservation.
