The aim of this study was to verify the safety and efficacy of transvaginal mesh by analyzing the 2-year follow-up data of patients performed by a surgeon with a high volume of procedures. Methods: A total of 617 patients with pelvic organ prolapse underwent transvaginal mesh by a single surgeon. Complications and anatomical status of each patient were examined up to 24 months after surgery. Risk factors for the recurrence were also analyzed.Results: Regarding complications, we experienced 10 patients (3.8%) of bladder injuries in anterior transvaginal mesh and eight (3.4%) in anterior and posterior transvaginal mesh. Massive blood loss was observed in four patients, but there was no case of blood transfusion. Mesh exposures were seen in seven patients (1.2%). A total of 100 patients (16.2%) had prolapse recurrence, defined as the Pelvic Organ Prolapse Quantification System stage ≥II. As to recurrences on the operated compartments, we observed five patients (2.0%) for anterior transvaginal mesh, three (6.5%) for posterior transvaginal mesh, five (7.4%) for combined transvaginal mesh, and 31 (14.2%) in anterior and posterior transvaginal mesh. Regarding Point C before operation in the anterior and posterior transvaginal mesh, the recurrence rates were more than 23% in patients with a Point C of 4 or more. Binominal regression analyses showed that higher body mass index, younger age, and higher stage of uterine prolapse were significant risk factors. Conclusions: The transvaginal mesh surgery is safe when conducted by experts. However, the recurrence rate may exceed 20% for high-stage uterine prolapse even when conducted by experts.

Aim In this study, we retrospectively analyzed the medium‐term efficacy and safety of surgery with transobturator two‐arm transvaginal mesh for cystocele and to verify whether the anterior arms are necessary for Japanese‐style transvaginal mesh surgery. Methods The study included 203 patients with cystocele who underwent transobturator two‐arm transvaginal mesh at our hospital between August 2015 and June 2017 and received appropriate follow‐up care for at least 48 months after surgery. Results The Pelvic Organ Prolapse Quantification stage was III in all the patients. Intraoperative complications included two cases of bladder injury and one case of more than 200 mL of blood loss. The mean observation period was 51.9 months, and prolapse recurred in the operated compartment in nine patients (4.4%). No cases of mesh exposure were observed. In comparing the preoperative characteristics of the 9 patients with prolapse recurrence at the surgical site with those of the other 194 patients, we found that the recurrence rate was significantly higher among patients in whom point Ba being 3.5 cm or more and among patients younger than 66 years. Conclusions Transobturator two‐arm transvaginal mesh for cystocele was as good and safe as the procedure previously reported with four‐arm mesh; thus, it was possible to omit the anterior mesh arms in Japanese‐style transvaginal mesh surgery. Patients should be informed preoperatively that prolapse recurs at a significantly higher rate among younger patients and in those whose point Ba being 3.5 cm or more.

Purpose This study established the prognostic significance of the uroflowmetry flow curve shape in the presence of voiding dysfunction following transvaginal mesh surgery. Methods This is a retrospective study of 439 symptomatic cystocele patients who underwent anterior wall repair with transvaginal mesh surgery. Uroflowmetry and postvoid residual were used to evaluate voiding function both preoperatively and 12 months postoperatively. The patients were divided into two groups: those with and without postoperative voiding dysfunction, and the predictors of postoperative voiding dysfunction were analyzed. The shape of the urine flow curve was analyzed for its influence on the presence of postoperative voiding dysfunction. Results Thirty‐five participants were in the voiding dysfunction group, while 404 were in the nonvoiding dysfunction group. Multivariate analysis was conducted by adding an interrupted‐shaped curve to age, Qmax, and postvoid residual, which showed significant differences in univariate analysis, found that age 68 years or older (odds ratio [OR]: 7.68, 95%CI 1.02–58, p = 0.048), postvoid residual ≥110 mL (OR: 2.8, 95%CI 1.25–6.29, p = 0.013) and interrupted‐shaped curve (OR: 2.47, 95%CI 1.07–5.69, p = 0.034) were discovered to be independent risk factors for the presence of voiding dysfunction after transvaginal mesh surgery. Conclusions Following transvaginal mesh surgery for cystocele, three variables were found to be predictive of voiding dysfunction: the old age, excessive postvoid residual, and an interrupted‐shaped flow curve. The uroflowmetry flow curve shape has the potential to be a new predictor of postoperative voiding dysfunction.
