RETROPERITONEAL LAPAROSCOPIC NEPHRECTOMY - ANIMAL AND HUMAN ANATOMIC STUDIES

Retroperitoneal laparoscopic nephrectomy with CO2 insufflation was per formed in 11 goats, The hemodynamic and blood gas repercussions of ret roperitoneal laparoscopy were compared during the first 30 minutes wit h those induced by intraperitoneal laparoscopy. With the animal placed in the left lateral supine position, the hemodynamic and blood gas ch anges were similar with the two techniques and had a similar time cour se, The technical feasibility of retroperitoneal laparoscopy in animal s was confirmed in the fresh human cadaver, The technical feasibility of retroperitoneal laparoscopy and the absence of any particular hemod ynamic and blood gas repercussions encourage us to develop this approa ch for clinical upper urinary tract surgery.
