[Study on the treatment of pelvic organ prolapse complicated with uterine myoma].

Objective: We studied the association between uterine myoma and recurrent pelvic organ prolapse (POP) after transvaginal mesh (TVM) repair.
Methods: Between June 2010 and January 2012, 103 female patients (mean age 67.8 years, mean parity 2.3, mean body mass index (BMI) 23.7) with POP underwent TVM procedures at our hospital. Sixtynine patients were qualified as stage 3 according to the POP quantification (POP-Q) system and 34 patients were stage 4. Twenty-six patients underwent anterior TVM (A-TVM) and 77 patients underwent anterior and posterior TVM (AP-TVM). All patients underwent a physical examination using the POP-Q system before and 6 month after surgery. Recurrence of prolapse was defined according to the International Continence Society by a measured value ≥ - 1, as most dependent portion of POP stage 2 or greater. One hundred-three patients were divided into group with uterine myoma larger than 5 cm in diameter and group without uterine myoma. Anatomical outcomes before and after TVM repair were compared between two groups.
Results: Preoperative Aa value, Ba value and gh value in group with uterine myoma were greater than in group without uterine myoma. Postoperative Aa value and Ba value in group with uterine myoma were greater than in group without uterine myoma, too. Postoperative recurrence of prolapse of stage 2 or greater was not found a statistical difference between two groups.
Conclusions: The risks of anterior vaginal wall descent seem to be high in POP with uterine myoma. Therefore it should be kept in mind on treatment choice.
