Single-Layer renal surface vs. standard three-layer approach in retroperitoneal laparoscopic adrenalectomy: surgical efficiency, learning curves, and recovery outcomes.

ABSTRACT:

Objective

To compare the perioperative outcomes and technical proficiency between the retroperitoneal laparoscopic single-layer renal surface approach (SLRS) and the standard three-layer approach (TLA) for benign adrenal tumors.

Methods

A retrospective cohort of 117 patients undergoing retroperitoneal laparoscopic adrenalectomy (66 TLA vs. 51 SLRS) was analyzed. Primary outcomes included operative metrics, postoperative recovery (drainage volume, fever incidence, catheter duration), and learning curves. Statistical analyses adjusted for pathological heterogeneity (covariate: cortical adenoma predominance in SLRS). Learning curves were quantified via linear regression slopes and moving-average stabilization thresholds.

Results

Baseline characteristics were comparable e
