ObjectivesTo 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.MethodsAn 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.ResultsMost 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).ConclusionModified 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.
