Novel technique of renal entrapment for morcellation

Purpose: Renal entrapment for morcellation can be a difficult task, often necessitating additional port placement and awkward maneuvering as well as concern with specimen sack breakage. We describe a novel technique that combines the best features of existing technology to allow easy entrapment and safe morcellation. Materials and Methods: We combined a 15 mm. EndoCatch II (United States Surgical Corp., Norwalk, Connecticut) introducer and frame with an 8 × 10-inch LapSac (Cook Urological, Spencer, Indiana) to facilitate entrapment with a strong reliable specimen sack. The LapSac is sutured in place onto the frame of the EndoCatch device with 3-zero sutures. The device is then rearmed and lubricated prior to introduction. Results: The described modification greatly enhances our ability more rapidly and easily to entrap nephrectomy specimens prior to tissue morcellation. No additional ports are needed and no morbidity has resulted from the use of the modified entrapment device. Introduction and deployment of the modified entrapment device is straightforward and easily reproducible. Conclusions: We recommend this easy and secure technique when tissue morcellation is being considered.
