[Ectopic gas as a complication of surgical kidney biopsy]

Since the complications herewith presented as a consequence of surgical renal biopsy are really exceptional and references found in the existing literature rare, we have considered that the contribution of these two cases which developed a pneumomediastinum-pneumoperitoneum and pneumocele prespectively during the immediate post-surgical period would be of interest. Evolution was favourable in both cases, with spontaneous resolution of the process.
