Laparoscopic partial nephrectomy and wedge resection.
Partial nephrectomy is a more challenging operation than radical or simple nephrectomy, primarily because of the risk of complications such as bleeding. This problem is even more troublesome with minimally invasive approaches because of the dearth of effective hemostatic instruments and supplies. The location of the lesion determines whether a transperitoneal or a retroperitoneal route will be employed. Centrally located or anterior renal lesions generally are approached transperitoneally whereas peripheral lateral or posterior lesions are accessed by retroperitoneoscopy. The Harmonic Scalpel with slow cutting and high coagulation settings is useful for incising the renal capsule and parenchyma. The argon beam coagulator is helpful to stop any persistent bleeding. The few reported series of laparoscopic partial nephrectomy indicate considerably longer operative times than are needed for open surgery and hospitalization of upwards of 5 days, largely to monitor drainage and urine leakage. It is hoped that this advanced laparoscopic technique will become more user friendly with further developments in techniques and instrumentation to provide patients with the expected benefits of minimally invasive surgery.
