Li, S. S. M. Hou, M. K. W. Li] Background: Kidney entrapment is generally considered to be a difficult step in retroperitoneoscopic nephrectomy (RN). Normally, a large device is needed to accommodate the specimen, which may measure ≤14 × 10 cm. There is just too little space to maneuver either the entrapment device or the specimen. Herein we describe a technique that can overcome this difficulty and even turn the space limitation to advantage. Methods: After the nephrectomy, the specimen is pushed caudally. A 15-mm Endocatch is inserted via the posterior cranial port. It is positioned strategically underneath the specimen so that when the entrapment bag is released, the specimen will have no room to move (because of the limited space) and will simply fall into the bag (because of gravity). Results: We have used this technique for our last four cases of retroperitoneoscopic nephectomy and found that it remarkably shortened the operative time for this step. Conclusion: One of the criticisms leveled against retroperitoneoscopic surgery concerns the problems posed by the space limitation. This technique turns the space limitation into an advantage and guarantees successful specimen entrapment.
