Mini-retroperitoneoscopic adrenalectomy: our experience after 50 procedures.

Objective: To present our experience with retroperitoneoscopic adrenalectomy using 3-mm instruments (mini-rA) for adrenal tumors.

Materials And Methods: From March 2009 to May 2013, patients with adrenal tumors <6 cm in size and body mass index ≤ 35 were involved in this prospective study and underwent mini-rA performed by 3-mm instruments. Demographic, endocrine and perioperative data, and cosmetic results (using Patient Scar Assessment Questionnaire and Scoring System) were recorded and analyzed.
