[Lumboscopic renal biopsy (author's transl)]

Renal biopsies with a new "lumboscopic" (half-open) technique were performed in 109 patients. Access to the kidney was gained by a small flank incision and biopsies from the renal cortex were taken under vision through the lumboscope. The biopsies were successful in all cases. The advantages of the new technique are convincing and lumboscopy suited to replace the regular open biopsy procedure.
