There are several techniques for repairing prolapse in the posterior vaginal compartment, yet there is no general agreement on the best surgical procedure. This study was performed to investigate the outcomes of the common vaginal route technique for posterior vaginal wall prolapse repair in the first Iranian fellowship teaching center for female pelvic floor disorders. This prospective cohort study was performed on women with posterior vaginal wall prolapse with or without prolapse of other vaginal compartments who underwent surgery between 2014 and 2018 in a referral center for female pelvic floor disorders. A follow-up period of 12 months was considered. Patients subjected to the transvaginal technique by attachment of the rectovaginal fascia to the pericervical ring using vaginal native tissue were included. Among the 107 patients, the Pelvic Floor Distress Inventory-20 (PFDI-20) scores were 141.87 ± 34.48 and 100.87 ± 26.48 before and after surgery, respectively, showing the significant improvement of patient’s symptoms after surgery in the 12-month follow-up. Comparing Pelvic Organ Prolapse Quantification (POP-Q) results before and after surgery, a significant improvement in patients’ conditions was seen at the 12-month follow-up. Based on the results of the present study, the surgical procedure of the rectovaginal fascia attachment to the pericervical ring in posterior vaginal wall prolapse repair seems an effective surgical intervention without significant morbidity in the short-term follow-up.

BACKGROUND፡ Pelvic organ prolapse is a common pelvic disorder among women. A standard staging system is needed to carefully evaluate the extent and severity of the disease, and initiate appropriate treatment. The aim of this study was to compare the two methods of standard and simplified pelvic organ prolapse quantification systems in clinical staging of Iranian women with pelvic organ prolapse.METHODS: This observational cross-sectional study was conducted on all women with complaints of seeing or feeling a vaginal lump or bulge and/or a dragging sensation who were presented to a pelvic floor disorders clinic of Imam Khomeini Hospital in Tehran, Iran, from October 2018 to June 2019. All patients were evaluated in terms of pelvic organ prolapse severity and staging using both instruments. Also, length of time needed to complete the questionnaires were calculated. After data collection, the results of pelvic organ prolapse staging and degree of agreement between two examiners were evaluated.RESULTS: A total of 120 women with mean age of 50.92±13.12 years were evaluated. It was shown that there is an almost perfect agreement (kappa coefficient > 0.8) between standard and simplified pelvic organ prolapse quantification systems in all the 3 compartments. Also, there was almost a twofold increase in the time needed to perform standard pelvic organ prolapse quantification (4.16±1.01 minutes) compared to performing simplified pelvic organ prolapse quantification (2.12±1.14 minutes) (p=0.03).CONCLUSION: According to the results of this study, there is a substantial and almost perfect agreement between standard and simplified pelvic organ prolapse quantification systems in clinical staging of Iranian women with pelvic organ prolapse. It seems that using simplified pelvic organ prolapse quantification system is more applicable in clinical practice for staging of pelvic organ prolapse, with high reliability coefficient.

Predicting survival time has many Effective implications in life quality management for the remainder of the patient's life. Also, survival data are highly variable and make accurate predictions difficult or impossible. Random Survival Forest by repeated tree construction on Bootstrap samples and averaging on the results of these trees reduce the prediction error and cause further generalization of these results. In this retrospective study, the records of 141 patients with epithelial ovarian cancer who were referred to the oncology and radiotherapy ward of Imam Hossein Hospital in Tehran from 2007 to 2018 were used. Random Survival Forest was fitted to the data to investigate the key factors affecting the first recurrence of epithelial ovarian cancer. The mean age of the patients in our study was 52 (23-82) years and the median time to the first recurrence in these was 17 (0.5-127) months, respectively. According to RSF results, using variable importance criterion (VIMP) metastatic tumor with relative importance 2.665 and also using minimal (MD) by depth 2.349, tumor stage with relative importance 1.993 and depth 2.678, and maximum platelet count with relative importance 2.132 and depth 2.683 were the most important variables affecting in the first recurrence of Epithelial Ovarian Cancer. One of the disadvantages of classical methods is the inappropriate fitting of many variables and the need for specific assumptions. More advanced methods such as RSF without the need for any specific assumptions with less prediction error can well explain event variations when exposed to high-dimensional data.

Ovarian cancer is one of the most deadly women's gynecological malignancies in the world, and despite the low prevalence, it accounts for about 5 of all cancer deaths in women. Survival analysis is a regression relationship between a set of variables with a specific outcome, which is considered disease survival or recurrence in medical studies. The aim of this study is to determine the important factors in the first recurrence of patients with epithelial ovarian cancer with two statistics methods. In this study, we review medical records of patients with epithelial ovarian cancer who referred to the oncology and radiotherapy department of Imam Hossein Hospital of Tehran from the beginning of 2007 to the end of 2018. Univariate and multivariate Cox regression, as well as the parametric Weibull method, were used to investigate the factors affecting patients' first recurrence. We perform all calculations with Stata Ver14. Of the 141 patients, 58 patients (41) had a first recurrence during our follow-up. The mean time to the first recurrence was 24.88 months. Univariate Cox regression and univariate Weibull analysis showed that metastatic tumor and tumor stage had highly significant effects in the first recurrence of epithelial ovarian cancer. In multivariate Cox and multivariate Weibull analysis, the metastatic tumor had a significant effect in the first recurrence of epithelial ovarian cancer. One of the causes of ovarian cancer recurrence may be diagnosis happened at late stages. Therefore, screening programs are needed to reduce illness and death from ovarian cancer. © 2020 Tehran University of Medical Sciences. All rights reserved.

Congenital absence of the vagina with variable uterine development known as Mullerian agenesis or Mayer-Rokitansky-Kuster-Hauser syndrome. Cervicovaginal agenesis in the presence of normal uterus is very rare. Conservative surgery has recently been suggested in patients with congenital cervicovaginal atresia in order to relieve the symptoms and maintain fertility. A 13-year-old female referred to a pelvic floor clinic, because of primary amenorrhea and severe cyclic pelvic pain. Ultrasonography revealed a large amount of blood accumulation in the uterine cavity, and also, the cervicovaginal agenesis was reported. Both ovaries were normal. A neovagina was created by dissection of the space between the bladder and rectum. Under ultrasonography guidance, two Pezzer catheters were inserted between uterine ending and neovagina, so the catheters kept the canal patent, a soft mould was applied to prevent the vaginal stricture. Cervicovaginal agenesis, accompanied by normal functional endometrium, is a rare but challenging Mullerian anomaly in the case of surgical treatment. One of the successful conservative treatment in a fully educated patient is the vaginal reconstruction and uterovaginal anastomosis by stenting and continues the application of vaginal mould.

Division of Female Pelvic Medicine and Surgery, Department of Obstetrics and Gynecology, Emam Khomeini Hospital, Tehran University of medical sciences proposed a clinically relevant algorithm to guide appropriate decision making based on underlying risk stratification and resource utilization in order to resume elective surgeries, following COVID-19 pandemic crisis. The consequence of standardized decision-making factors and transparency of the principles will provide more assurance, consistency, and reliability on both sides, care providers and the patient. It also will decrease ethical dilemmas and moral criticism for surgeons. Eventually, this approach is applicable in any other disaster preparedness as a logical stratification of surgical indications for the female pelvic floor surgical procedures.

OBJECTIVE To investigate the effect of subendometrial vasopressin injection in patients with abnormally invasive placenta (AIP), who underwent cesarean section and hysterectomy. METHODS This randomized double-blinded clinical trial was conducted on pregnant women diagnosed with AIP grade 4 and 5 by ultrasonography during cesarean section. Women were randomly divided into two equal groups including group 1 (vasopressin) and group 2 (control) who underwent 20 units of vasopressin and 20 cc normal saline injection, respectively. Vasopressin and placebo were injected subendometrially 1 cm medial to the uterine vessels into the lower uterine segment. The exclusion criteria include presence of myocardial infarction, cardiomyopathy, congestive heart failure, uncontrolled hypertension, chronic obstructive pulmonary disease, pelvic malignancy. The outcome of the study was total quantitative blood loss during the cesarean section. We estimated blood loss by measuring the blood volume in one of the suction bottles with addition for weight changes of mops, pads, and soaked linen savers. RESULTS Sixty patients were recruited into the study, 30 as the vasopressin group and 30 as the controls; with no excluded case. The amount of bleeding in the vasopressin group was significantly lower compared with that in the control group (P

Objective: To report the neglected pessary in a patient with pelvic organ prolapse. Pelvic organ prolapse (POP) is one of the most important medical challenges in women especially elderly. One of the conservative treatments of symptomatic POP is pessary placement. Case report: A 84-year-old woman, para 10 was referred to female pelvic floor clinic of an academic hospital for vaginal bleeding and neglected vaginal pessary. Vaginal examination in the pelvic floor clinic revealed an entrapped ring pessary in severely atrophic vaginal mucosa with purulent discharge. Conclusion: Although pessary is the first choice and one of the best conservative treatment for pelvic organ prolapse, it shouldn’t be used for poor cooperative patient who cannot comply with regular follow-up visits which may cause harmful complications.

Pelvic organ prolapse is a common complaint among older women. Vaginal pessary insertion is an appropriate treatment as a non-surgical method with few complications. This paper is a prospective observational study of 68 patients with pelvic organ prolapse that was carried out at the Imam Khomeini Hospital’s Pelvic Floor clinic. The degree of pelvic organ prolapse was graded according to the Pelvic Organ Prolapse Quantification (POP-Q) System. For all patients, the Pelvic Floor Distress Inventory-20 (PFDI-20) questionnaire was completed before vaginal pessary insertion, and after approximately 6 months of treatment. After 6-8 months, we found out that vaginal discharge was significantly increased and the feeling of fullness in the vagina was significantly decreased. However, sexual dissatisfaction, the feeling of incomplete evacuation, fecal and urinary incontinence, frequent urination, and pain or discomfort in the genital region were not significantly different after using a pessary. Approximately half a year later, 96.7% of the women with a successful pessary fitting trial were satisfied and reported a significant improvement in symptoms. Further studies with larger sample size, a different type of pessary, and a longer follow-up duration are recommended to evaluate all the symptoms associated with pelvic organ prolapse and its treatment.

Our aim was to explore the experiences of Iranian postmenopausal women who sought medical help for their symptomatic vulvovaginal atrophy (VVA).Five focus group discussions (FGDs) were conducted. Participants had to be postmenopausal; had bothersome symptoms of VVA for which they came to the clinic; had previously sought medical help for their VVA; and had confirmed physical signs of VVA upon examination by a gynecologist.Twenty-five women, aged 49-60 years participated in the five FGDs. Twenty women said they currently had1 VVA symptom at presentation to the clinic. Four major themes emerged from the women's narrative stories: (1) negative impact of VVA on women's life, (2) psychological distress associated with VVA, (3) negative impact of VVA on marriage and relationship, (4) inadequate symptom relief from available treatments due to lack of awareness of VVA treatment options. None of the participants reported ongoing treatment of their VVA with local low-dose estrogen. Women further commented that, although local estrogen products were costly, they would like to use them if they were prescribed.Considering the negative impact of VVA symptoms on women's lives, health professionals in Iran should be prescribing approved and effective therapies for symptomatic women.

The current evidence regarding the association between vitamin D status and pelvic floor disorder (PFD) are inconclusive. This meta-analysis was aimed to summarize existing data demonstrating the association between Vitamin D status and PFD using published observational studies. All national and international databases including Web of Science, PubMed, Google Scholar, and Scopus were searched up until January 30, 2018, and related published studies retrieved for meta-analysis. The effect sizes of Vitamin D status were presented as standardized mean difference (SMD) with 95% confidence interval (CI), using random-effect models and inverse variance method. The Cochran Q statistic and I2 tests were used to evaluate the heterogeneity across included studies. Seven studies with 3219 women were included our meta-analysis. There was heterogeneity existing among included studies (I2 = 96.4%, P < 0.001), so a random-effect model was used. The findings of this meta-analysis revealed that the mean serum Vitamin D levels in women with PFD were significantly lower than healthy women (SMD −0.60; 95% CI, −1.06, −0.13; P = 0.01). This meta-analysis demonstrates lower levels of serum Vitamin D in women with PFD rather than healthy women. Additional prospective studies regarding the association between Vitamin D status and PFD are required to confirm our findings.

Summary Objective The aim of this study was to compare the effects of the transverse muscle-cutting Maylard incision and the Pfannenstiel incision for hysterectomies, in terms of postoperative complications, pain, and quality of life. Materials and Methods This randomized, double-blind study compared two laparotomy techniques. All hysterectomies were performed for benign conditions. Eighty cases were randomly assigned to receive either Pfannenstiel or Maylard incisions. Measured intraoperative variables included volume of blood loss and duration of surgery. Postoperative variables included abdominal distension, postoperative pain, and quality of life. Results Postoperative abdominal distension was significantly lower in the Maylard group ( p = 0.004). There were no differences in intraoperative characteristics and duration of hospitalization, hemorrhage volume, or duration of surgery between the two groups. Conclusion Hysterectomy performed via the Maylard incision was associated with the use of fewer additional analgesics than hysterectomy performed via the Pfannenstiel incision.
