Paradigm shifts
1. Integral Theory, 1993 (Peter Petros)– Creating neoligaments using tapes– Reinforcement of pubourethral ligament– Midurethral tape placement.
2. Transobturator Approach, 2001 (Delorme)- Reinforcement of urethropelvic ligament- Less visceral and vascular complications- Less irritative voiding symptoms

Obturator - Neuroanatomy
• From anterior division of L2-4• Innervates all muscles of the obturator region,
except pectineus• Passes through obturator canal and splits to
innervate the muscles that adduct the thigh and help with external rotation
• Small sensory area on the medial thigh
