Outcomes of a novel modified total colpocleisis for advanced pelvic organ prolapse in elderly women and its efficacy on lower urinary tract symptoms

OBJECTIVES

To evaluate the effectiveness of modified total colpocleisis for advanced pelvic organ prolapse (POP) in elderly women and to assess the improvement in lower urinary tract symptoms (LUTS) of the patients.

METHODS

An observational cohort study was conducted, including 105 POP patients who underwent modified total colpocleisis between April 2020 and December 2022. The study analyzed the patients' demographic characteristics, perioperative outcomes, and follow-up outcomes, including complications, remission of LUTS, satisfaction rates, and regret rates. Confirming the safety, durability, and patient satisfaction of modified total colpocleisis.

RESULTS

Most patients (95/105, 90.5%) had more than one comorbidity. Eighty-six (81.9%) had a concomitant hysterectomy, the average operative time was 112.78 ± 34.92 min, with a median estimated bleeding of 50 mL (10-300 mL). Perioperative changes in hemoglobin and hematocrit were 11.64 ± 10.03 g/L and 3.87% ± 3.05%, respectively. Urinary retention was the most common complication (10/105, 9.5%). With a median follow up of 16 months (3-35 months), 101 patients (96.2%) reported satisfaction with the results of the procedure, with none reporting regret. Both subjective and anatomical recurrence rates were quite low (2.9% and 5.7%, respectively). Twenty-three (21.9%) had de novo urinary incontinence, and the remaining LUTS such as frequent, urgent, hesitation, and difficulty emptying were significantly improved (P < 0.05).

CONCLUSION

Modified total colpocleisis is an effective treatment option for elderly women with severe POP. This procedure can significantly improve several LUTS, and most de novo incontinence is mild and has a limited impact on patients' quality of life.

A new 3D stress MRI measurement strategy to quantify surgical correction of prolapse in three support systems

AIMS

The aim of this study was to develop and test the feasibility of a magnetic resonance imaging (MRI)-based measurement strategy to evaluate the effectiveness of surgical procedures in restoring normal anatomy in all three systems of pelvic floor support and quantify the structural changes induced by prolapse surgery.

METHODS

Patients underwent clinical examination and stress MRI preoperatively and again 3 months postoperatively. Preoperative and postoperative measures of three MRI-based structural support systems were made: (1) vaginal wall, (2) apical and paravaginal support, and (3) hiatal closure system. Preoperative to postoperative structural changes were calculated and compared to normal values, and bivariate associations were determined.

RESULTS

The three structural support systems were successfully quantified for both preoperative and postoperative MRIs regardless of operative approaches in all 15 women in the pilot group. Apical support was restored to normal in 11 of 12 patients who underwent an apical suspension procedure and 9 of 14 patients with a posterior repair had normalization of genital hiatus size. Mid-vaginal paravaginal location was elevated an average of 2.5 ± 2.0 cm despite no paravaginal repairs being performed. Paravaginal location improvements were also significantly correlated with apical elevation (r values 0.99-0.87, p < 0.001).

CONCLUSIONS

A strategy that quantifies structural-specific preoperative impairments and improvements after prolapse surgery was successfully developed. Early findings reveal that prolapse surgery is more successful in restoring normal anatomy at Level I than Level III. Improvement in paravaginal location is significantly correlated with apical elevation.

Paravaginal defect: A new classification of fascial and muscle tears in the paravaginal region

The lateral support of the vaginal wall depends on the integrity of the paravaginal section of the visceral pelvic fascia, levator ani, and their connection. Various defects of the muscle and fascia can result in identical clinical findings-ie, the descent of the lateral vaginal sulcus. In this study, we created a realistic scheme for classifying paravaginal defects, based on the complex relationship of the pelvic fascia with the levator ani. Surgical observations, cadaver examinations, and a complex magnetic resonance imaging (MRI)-based 3-dimensional (3D) model were used to analyze the spatial relationships of normal and defective anatomy of the female pelvic floor. Descent of the lateral vaginal sulcus can result from a defect in the paravaginal visceral pelvic fascia, levator ani, or both. The fascial defect can be partial or complete, and the muscle defect can vary in location. A detailed illustrated classification is presented. We present a new model of the pathology that underlies a common clinical finding.
