Radiofrequency ablation (RFA) has been most effective when the tumors are small, exophytic, and away from vital structures. We enlarged the size of the ablation kill zone by infusing a 30-nm tumor necrosis factor–α and polyethylene glycol–coated gold nanoparticle (CYT-6091, CytImmune Sciences, Inc.) before ablation in a rabbit kidney tumor model.A total of 37 New Zealand White rabbits had VX-2 tumors...
Purpose The rate of unintentionally discovered renal masses has been increasing along with a parallel increased incidence of renal cell carcinoma both in men and women. Ablation therapy has emerged as an alternative for the treatment of these small renal tumors. Several techniques have been developed for renal tumor ablation with cryoablation (CA) and radiofrequency ablation (RFA) being among the...
A complication is reported in which Lapra-Ty absorbable suture clips (Ethicon EndoSurgery) migrated from a laparoscopic partial nephrectomy bed into the collecting system, causing renal colic. During surgery performed with hilar occlusion, visual inspection did not reveal collecting system entry. Transected vessels were oversewn with absorbable suture secured with Lapra-Tys. Absorbable bolsters were...
