Abstract
The Pelvic Organ Prolapse Quantification (POP-Q) stages do not correlate with symptoms or characterize important prolapse subtypes.
We hypothesize that clinically meaningful prolapse "phenotypes" utilizing POP-Q measurements can be defined. The primary aim was to define the phenotypes and their frequency. Secondary aims were to compare demographics, medical characteristics, and symptoms between phenotypes.
Patients who previously underwent prolapse surgery were retrospectively categorized into 1 of 8 phenotypes based on 2 principles: (1) prolapse exists when the anterior or posterior vaginal wall descend to the hymen or the apex descends half total vaginal length, and (2) prolapse may exist in anterior, posterior, and/or apical compartments. Demographics, medical characteristics, and Pelvic Floor Distress Inventory-20 (PFDI-20) responses were compared. Linear and logistic regression models were used for comparisons.
The AC (anterior-predominant and apical) phenotype was most common (231 of 501 patients, 46.1%) and served as the reference for comparisons. The no prolapse, P (isolated posterior), C (isolated apical), and PC (posterior-predominant and apical) phenotypes were younger. The A (isolated anterior) phenotype was older. P, PC, and APC (anterior and posterior and apical) phenotypes had greater body mass index. The P phenotype Colorectal-Anal Distress Inventory scores were higher. Similarly, the PC phenotype had higher scores for bowel splinting and rectal prolapse. Conversely, the C phenotype total PFDI-20 scores were lower (P = 0.01). Only the APC phenotype had no significant differences in any PFDI-20 question compared with the AC phenotype.
These phenotypes may allow for improved understanding, communication, and counseling about prolapse and prolapse treatment.
