  Laparoscopic renal biopsy is known for its reliability in sample collection and safety with low complication risk. In the clinical research conducted at our hospital with the theme of “the Study of renal tissue damage in primary aldosteronism”, the department of urology was in charge of laparoscopic adrenalectomy and laparoscopic renal biopsy. We report on the precautions and safety in the procedure.  Patients with primary aldosteronism with unilateral adrenal involvement enrolled in the clinical study were included. After laparoscopic adrenalectomy, specimens were collected by puncturing the upper pole of the kidney on the affected adrenal gland side three times with an 18 G puncture needle according to the research protocol. Bleeding from the puncture site with or without macroscopic hematuria was controlled endoscopically with forceps until the bleeding ceased.  In a total of 5 cases, sufficient glomeruli were harvested, and none required intervention due to complications. We noted the following of removal of perinephric fat tissue at the planned puncture site, tracking of the puncture needle with an endoscope, assumption of the site when the puncture needle penetrates, traction of the kidney to a position with forceps to puncture easily. A safe laparoscopic renal biopsy was able to be performed, albeit under the special circumstances of the clinical study, by paying attention to several points.
