Sagittal Double‐Hump Deformity of the Lumbosacral Spine: An Anatomical Risk Factor for Surgical Landmark Obscuration During Laparoscopic Sacrocolpopexy

Neurourology and Urodynamics, Volume 45, Issue 3, Page 591-599, March 2026.
ABSTRACT Objective This prospective study evaluated the impact of the “double‐hump” deformity—defined by anterior protrusions of the L4–L5 and L5–S1 disks—on L5–S1 angulation and laparoscopic sacrocolpopexy (LSC) outcomes. We hypothesized that this deformity is associated with reduced angulation and impaired sacral promontory visibility. Methods The L5–
