Pictorial diagnostic algorithm. Symptoms indicate which ligaments are damaged. Tick every box where a symptom occurs, and the diagnosis of ligament and damage-associated prolapse appears. The rectangle indicates the symptoms associated with USL laxity. The height of the bar indicates the probability of association of a symptom with a particular zone. The connective tissue structures causing prolapse and pelvic symptoms fall naturally into 3 zones. Anterior zone: external meatus to bladder neck. Middle zone: bladder neck to anterior cervical ring. Posterior zone: posterior cervical ring to PB. CPP and nocturia are uniquely caused by USL laxity, stress urinary incontinence by PUL, pubourethral ligament; hammock, suburethral vagina. EUL, external urethral ligament; CL, cardinal ligament; PCF, pubocervical fascia; ATFP, arcus tendinous fascia pelvis; PB, perineal body; RVF, rectovaginal fascia; USL, uterosacral ligament.
