Laparoscopic Renal Biopsy via Retroperitoneal Approach

Abstract

Renal biopsy was performed in 17 patients using the balloon technique of endoscopy of the retroperitoneum. There was good exposure of the kidney and a sufficient amount of renal tissue was obtained in all patients with minimum postoperative morbidity. The preliminary results show that this method could become a safe and reliable alternative to open surgical biopsy.
