[A topographic anatomical basis to approaches for instrumental interventions in diseases of the organs of the retroperitoneal space].

Retroperitoneoscope was introduced through the 11 and 10 intercostal space by linea axillaris media and anterior Differences of the accesses between each other and between those in lumbocostal angle are statistically significant. The access to 11 intercostal space was proved to be the most convenient one for the examination of the entire kidney surface, while the one to 10 intercostal space-for the endoscopy of adrenals and caudal region of the pancreas. The caput of the pancreas may be examined both through 11 intercostal space and lumbocostal angle. Clinical observations of 129 patients, operated by means of retroperitoneoscope through 11 intercostal space confirmed the effectivity of the method. Positive effects of retroperitoneoscopy_-minimal traumatization of tissues, normal postoperative period and good cosmetic effect make it suitable for wide introduction into the surgical practice.
