The Austrian Sacrocolpopexy Registry: Surgical Techniques, Perioperative Safety, and Complications.

STUDY OBJECTIVE: Sacrocolpopexy (SCP) has become the standard procedure to correct uterovaginal prolapse in women, but techniques and approaches are not standardized. We report the results of the Austrian Sacrocolpopexy Registry, which aimed to collect data on surgical techniques and perioperative outcomes. DESIGN: The Austrian Urogynecology Working Group initiated a registry to assess surgical variability and perioperative safety of SCP. The study was performed at 14 centers (13 in Austria,1 in Switzerland). Institutional review board approvals were obtained. PATIENTS: Consecutive patients with symptomatic pelvic organ prolapse (POP). INTERVENTIONS: SCP in the course of routine POP treatment. MEASUREMENTS AND MAIN RESULTS: Preoperative assessment included demographic data, clinical data on bladder, and bowel functions and POP-Q status. Surgical data included surgical approach (open, laparoscopic, robotic), type of mesh, depth of dissection, nerve sparing techniques, suture materials, uterus or cervix-sparing techniques, peritoneal closure, and concomitant surgeries. A total of 401 patients were recruited into the study. The mean age was 57 years (range: 26-84) and mean body mass index was 34. A total of 137 (34%) patients had undergone previous surgery for prolapse and in 264 cases SCP was the primary procedure. A total of 170 (42%) patients had undergone previous hysterectomy; For patients with uterus, SCP was performed with subtotal (n = 148) or total (n = 3) hysterectomy. A total of 285 (71%) SCPs were done laparoscopically, 102 (25%) robotically and 10 (3%) per laparotomy. The conversion rate from laparoscopy to abdominal surgery was 4.5%. Various meshes and suture materials were used and fixation techniques also varied widely. Four patients underwent reoperation within 30 days (2 trocar herniations, and 1 bowel obstruction, 1 compartment syndrome). One patient died of aortic dissection 7 days after SCP. CONCLUSIONS: Most SCPs in this registry were performed laparoscopically, but there was considerable variation in surgical techniques. Perioperative morbidity appears modest.

Psychometric properties and validation of two global impression questionnaires (PGI-S, PGI-I) for stress incontinence in a German-speaking female population.

AIMS: The Patient Global Index of Severity (PGI-S) and the Patient Global Index of Improvement (PGI-I) are global impression questionnaires developed in English and validated in women with stress urinary incontinence (SUI). This validation study tested the psychometric properties of German-language versions of the two questionnaires in German-speaking women with SUI. METHODS: The German-language PGI-S and PGI-I were psychometrically tested and validated using the SF-12 questionnaire, the Kinǵs Health Questionnaire (KHQ), clinical parameters, incontinence episode frequency and pad use in 311 patients before and 3 months after receiving a TVT-O or TVT tape for SUI. RESULTS: At baseline and 3 months postoperatively there was a positive correlation between PGI-S response categories and clinical parameters, IEF and pad use, and nearly all KHQ subscales. There were no correlations between response categories of PGI-S at baseline and PGI-I at 3 months and the SF-12 scales PCS-12 and MCS-12. CONCLUSION: Our results demonstrated good psychometric properties of the German-language PGI-S and PGI in German-speaking women with SUI.

German translation and validation of the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-IUGA revised (PISQ-IR).

INTRODUCTION AND HYPOTHESIS: Condition-specific sexual questionnaires are essential for clinical trials and important patient-reported outcome measures. The aim of the study was to translate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-International Urogynecology Association Revised (PISQ-IR) into German and to clinically validate it in a German-speaking population. METHODS: The translated PISQ-IR was linguistically validated in two rounds of cognitive interviews. The final instrument was psychometrically validated in women presenting to urogynecological clinics with pelvic floor dysfunction. For analysis of criterion validity, three related self-reported measures were administered: the Female Sexual Function Index (FSFI), the Kings Health Questionnaire (KHQ), and the 36-Item Short Form Health Survey (SF-36). For external validity, PISQ-IR subscales were compared to the clinical-measures Pelvic Organ Prolapse Quantification system (POP-Q) stage, pelvic floor muscle tone, and Oxford Grading Scale. Descriptive statistics, floor and ceiling effects, internal consistency using Cronbach's alpha coefficient, and Pearson correlations were calculated for all PISQ-IR subscales. RESULTS: The PISQ-IR was completed by 197 women, out of whom 66 (33.5 %) considered themselves not sexually active (NSA) and 131 (66.5 %) as sexually active (SA). Participants' mean age was 57 ± 12 years; 50 % were diagnosed with symptomatic POP, 74 % with urinary incontinence (UI) and 4 % with anal incontinence (AI). The PISQ-IR subscales were analyzed separately for SA and NSA women with Cronbach's alpha coefficients ranging from 0.64 to 0.94. Moderate to high correlations were observed between PISQ-IR subscales and related quality of life (QoL) scales and corresponding FSFI scales. CONCLUSION: Initial testing of the German PISQ-IR suggests it is an internally consistent and valid tool for use in clinical practice and research.

Rates and Routes of Hysterectomy for Benign Indications in Austria 2002 - 2014.

INTRODUCTION: Rates and routes of hysterectomy have implications for quality, costs and training. This study analyzed rates of benign hysterectomy and surgical approaches for benign hysterectomy in Austria from 2002 to 2014. MATERIAL AND METHODS: This was a population-based retrospective observational study of coding data from all acute care hospitals (public and private) in Austria. Main outcome measures were numbers of women undergoing hysterectomy for benign indications in Austria per year and the route of hysterectomy for benign indications. RESULTS: The number of benign hysterectomies performed per year declined from 10 675 in 2002 to 7747 in 2014, a decline of 27%. The use of vaginal hysterectomy was stable (53% and 47%, respectively). Use of laparoscopic techniques increased (5% in 2002, 32% in 2014) whereas use of abdominal hysterectomy decreased (41% and 20%, respectively). CONCLUSIONS: Numbers of benign hysterectomies performed per year in Austria declined substantially between 2002 and 2014. Use of vaginal hysterectomy was stable at about 50%, whereas increased use of laparoscopic techniques was associated with lower rates of open hysterectomy.

Bladder and rectum dose defined from MRI based treatment planning for cervix cancer brachytherapy: comparison of dose-volume histograms for organ contours and organ wall, comparison with ICRU rectum and bladder reference point.

PURPOSE: To analyze the correlation between dose-volume histograms based on organ contour and organ wall delineation for bladder and rectum, and to compare the doses to these organs with the absorbed doses at the ICRU bladder and rectum reference points. MATERIAL AND METHODS: Individual MRI based brachytherapy treatment planning was performed in 15 patients as part of a prospective comparative trial. The external contours and the organ walls were delineated for the bladder and rectum in order to compute the corresponding dose-volume histograms. The minimum dose in 2 cm(3), 5 cm(3) and 10 cm(3) volumes receiving the highest dose were referred to as [D2], [D5] and [D10] and compared with the absorbed dose at the ICRU rectum and bladder reference point. RESULTS: The bladder (bext) and rectal (rext) doses derived from external contours and computed for volumes of 2 cm(3) [D2], provided a good estimate for the doses computed for the organ walls (bw and rw) only (mean ratio [D2](bext)/[D2](bw)=1.1+/-0.2 and [D2](rext)/[D2](rw)=1.2+/-0.1, respectively). This correspondence was no longer true when larger volumes were considered (5 and 10 cm(3)). The dose at the ICRU rectum reference point did overestimate the dose computed for 2 cm(3) of the rectum wall (mean ratio: 1.5+/-0.4). In contrast, the dose at the ICRU bladder reference point did-in the case of inappropriate topographic location of the balloon-underestimate the dose computed for 2 cm(3) of the bladder wall (overall mean ratio: 0.9+/-0.4). CONCLUSION: For clinical applications, when volumes smaller than 5 cm(3) are considered, the dose-volume histograms computed from external organ contours for the bladder and rectum can be used instead of dose-volume histograms computed for the organ walls only. External organ contours are indeed easier to obtain. The dose at the ICRU rectum reference point provides a good estimate of the rectal dose computed for volumes smaller than 2 cm(3) [D2] only for a midline position of the rectum. The ICRU bladder reference point provides a good estimate of the dose computed for the bladder wall [D2] only in cases of appropriate balloon position.

The impact of sectional imaging on dose escalation in endocavitary HDR-brachytherapy of cervical cancer: results of a prospective comparative trial.

PURPOSE: The purpose of this comparative prospective study was to assess the effect of CT and MR based individualisation and adaptation on the dose distribution in the target volume and organs at risk compared to a radiography based procedure. MATERIAL AND METHODS: In 15 patients MR scans, in 10 patients additional axial CT-scans with compatible tube-ring applicator in situ were performed and digitally transferred to the PLATO(R) planning system. Considering clinical examination and MR-scan before radiotherapy individual 3-D dose distribution was calculated and adapted based on (1) two orthogonal radiographs; (2) isodoses superimposed on the CT images; and (3) isodoses superimposed on the MR images. Adaptation was strictly limited by the dose level at 2 cm(3) bladder or rectum volume (D(2)) to allow comparison of CT and MR plans. All three individualised dose distributions were superimposed on the MR images and cumulative dose-volume histograms were calculated for comparison. RESULTS: 3-D individualisation based on sectional imaging enabled higher dose to the target volume (isodose enclosing 95% of the CTV=CTV(95)) compared to individualised treatment plans based on orthogonal radiographs by a mean factor of 1.2 (1-1.7). The dose to bladder and/or rectum wall was at the same time not increased beyond the prescribed tolerance level (71% of the prescribed target dose). In a subgroup of 10 patients MRI based treatment plans were superior to CT based treatment plans allowing for a higher dose (138% vs. 124%). CONCLUSION: Sectional imaging based treatment planning, in particular using MR, was superior to radiography allowing for a clinical meaningful dose escalation without increasing the dose to bladder and rectum beyond the tolerance level.
