Post Operative Pain, Acute Clinical Trial
Official title:
Prospective Randomized Comparison of Needlescopic Versus Conventional Laparoscopic Adrenalectomy for Unilateral Adrenal Tumors Less Than 4 cm in Diameter Among Patients With Primary Aldosteronism
The investigator conduct a randomized clinical trial for the needlescopic and conventional laparoscopic adrenalectomy to assess whether mini laparoscopic adrenalectomy is better than conventional laparoscopic adrenalectomy in terms of pain, complication rate , and wound cosmetics
If the participant with unilateral PA tumor less than 4cm is willing to enter the clinical trial, he/she will be randomly assigned to two groups (conventional vs needlescopic laparoscopic adrenalectomy) in a 1:1 ratio, followed by preoperative assessement. All procedures were performed by experienced laparoscopic urologists (number of complex laparoscopic procedures > 50 cases/yr for 10 yrs). The participant were blinded to the type of surgical procedure underwent until the pain assessment was completed in the morning of the second days after surgery ;
