Accuracy of postvoid residual volumes after vaginal delivery: a prospective equivalence study to compare an automatic scanning device with transurethral catheterization.

INTRODUCTION AND HYPOTHESIS: Abnormal postvoid residual volumes (PVRV) after delivery are common in daily clinical practice. By using an automatic scanning device, unnecessary catheterizations can be prevented. The aim of this study was to determine the accuracy of PVRV after vaginal delivery measured by an automatic scanning device through a comparison with transurethral catheterization. MATERIALS AND METHODS: This prospective observational equivalence study was performed in patients who delivered vaginally between June 2012 and May 2017 in three teaching hospitals in The Netherlands. After the first spontaneous void after delivery, postvoid residual volume (PVRV) was measured with a portable automatic scanning device (BladderScan® BVI 9400). Directly afterward, it was measured by catheterization. Correlation between measurements was calculated using Spearman's correlation coefficient and agreement plot. The primary outcome was to validate the correlation between the BladderScan® compared with the gold standard of transurethral catheterization. RESULTS: Data of 407 patients was used for final analysis. Median PVRV as measured by BladderScan® was 380 ml (± 261-0-999 ml) and by catheterization was 375 ml (± 315-1800 ml). Mean difference between measurements was -12.9 ml (± 178 ml). There was a very good correlation between methods (Spearman's rho = 0.82, p < 0.001). Using a cut-ff value of >500 ml, specificity and sensitivity were 85.4 and 85.6%, respectively. CONCLUSIONS: The BladderScan® (BVI 9400) measures PVRV precisely and reliably after vaginal delivery and should be preferred over catheterization.

Compliance to clinical guidelines for early-stage epithelial ovarian cancer in relation to patient outcome.

OBJECTIVES: To assess compliance to current surgical staging and adjuvant treatment guidelines for patients with early-stage epithelial ovarian carcinoma and its impact on overall survival. METHODS: Patients diagnosed between 1991 and 1997 with early-stage ovarian cancer were recruited from the Regional Cancer Registry of the central region in the Netherlands. Demographic data, tumour characteristics, surgical findings and therapeutic data were abstracted from medical records. Patients were classified into optimal and non-optimal surgical staging. Overall survival was estimated using Kaplan-Meier method. To adjust for age hazard ratios for overall survival were estimated with a Cox Proportional Hazards model. RESULTS: One hundred and twenty-five patients were included in the study, 41 of them (32.8%) were optimally staged. Guidelines for adjuvant radio- or chemotherapy were adequately followed in all 62 grade I patients and in 44 out of 59 grade II and III patients (74.6%). During 734.6 person-years of follow up 31 patients died. Five-year overall survival figures were 97.6% in the optimally staged group and 68.5% in the non-optimally staged group. Patients who were non-optimally staged, had a significant higher risk to die than those who were optimally staged (HR: 7.4; 95% CI: 1.7-32.2). In patients with a grade II and III tumours, complete surgical staging still had a significant influence on survival (HR: 3.8; 95% CI 1.7-8.3). In women with grade II or III tumours, adjuvant radio- or chemotherapy administered in accordance to the guidelines did not improve overall survival regardless whether they were optimally staged or not. CONCLUSION: Incomplete staging in early-stage ovarian cancer leads to gross mis-classification in grade II and III tumours and to a lesser extent in grade I tumours. This leads to undertreatment in both surgical and adjuvant therapy. Subsequently unnecessary deaths may occur. More effort must be put in identifying obstacles interfering with compliance of guidelines.

Severe anemia in pregnancy in rural Ghana: a case-control study of causes and management.

BACKGROUND: Various factors contribute to severe anemia in pregnancy in low-income countries. This study assesses which of these are of importance in rural Ghana, and evaluates management. METHODS: Prospective case-control study in two (sub)district hospitals in rural Ghana among 175 severely anemic pregnant women (Hb < 8.0 g/dl), receiving a comprehensive treatment package; and 152 non-anemic pregnant women (Hb > or = 10.9 g/dl), giving birth at the study hospitals, matched for age and parity. Evaluated characteristics were need for treatment for urinary tract infection and schistosomiasis; sickle cell and HIV status; antenatal care characteristics; and Hb increase after treatment. Statistical analysis included Chi square test and general linear modeling. RESULTS: Associated with severe anemia were multiple pregnancy (OR 8.9; 95%CI 1.1-71.0), urinary tract infection (OR 6.2; 95%CI 3.5-11.0), residence outside study (sub)district (OR 2.7; 95%CI 1.7-4.3), body mass index < 20.0 (OR 2.0; 95%CI 1.2-3.4), and less than 4 antenatal clinic visits (OR 1.9; 95%CI 1.2-3.0). No association was found with sickle cell or HIV status, schistosomiasis treatment, blood loss in pregnancy, or gestational age at antenatal care registration. After treatment, mean Hb in the severe anemia group increased by 3.2 g/dl, significantly more than in the control group (0.2 g/dl; p<0.001). Modeling showed that the number of antenatal visits and the lowest Hb together explained approximately 25% of the variability in Hb prior to childbirth among women with severe anemia. CONCLUSIONS: Treatable causes contribute considerably to severe anemia in pregnancy in low-income countries. Even with limited resources, a substantial increase of Hb can be achieved.

Effects of genital prolapse surgery on sexuality.

OBJECTIVE: A prospective study was performed to evaluate the effects of genital prolapse surgery on sexuality. Additionally we investigated which variables are risk factors for persistence or development of sexual problems after surgery. METHODS: All 82 patients participating in a randomized trial comparing vaginal and abdominal surgical correction of descensus uteri, were asked to complete the Questionnaire for screening Sexual Dysfunctions (QSD) before and at six months and one year after surgery. RESULTS: Sixty-two patients completed the questionnaire. General satisfaction about sexuality was significantly improved after surgery. Of 41 patients who were sexually active both before surgery and at one year after surgery, 28 (68.3%) patients reported sexual problems before surgery. In 13 (46.4%) of these patients, all sexual problems disappeared. Of the 13 patients without sexual problems before surgery, two patients reported de novo sexual problems. The relative risk on disappearance of sexual problems in patients with large cystocele was 1.5 (95% confidence interval 1.1-2.1) times higher than the risk in patients without large cystocele. CONCLUSION: Satisfaction about sexuality increases and the prevalence of sexual problems decreases in patients undergoing surgical correction of descensus uteri.

Compliance to surgical and radiation treatment guidelines in relation to patient outcome in early stage endometrial cancer.

RATIONALE, AIMS AND OBJECTIVES: We evaluated the adherence to treatment guidelines in early stage endometrial cancer and the influence of adherence to guidelines on overall survival. METHOD: Patients were identified in the central region in the Netherlands from 1990 till 1995. Patient and tumour characteristics, surgical findings, radiation and follow-up data were abstracted from medical records. Endpoint was overall survival. Kaplan-Meier method was used to perform time-to-event analysis. Hazard ratios for overall survival were estimated with a Cox Proportional Hazards model. RESULTS: 359 patients were eligible for analysis. 335 patients presented with a clinical stage I cancer. 333 patients underwent a Total Abdominal Hysterectomy with Bilateral Salpingo Oophorectomy (TAH/BSO), of which 301 were staged as International Federation of Gynaecology and Obstetrics (FIGO) stage I, whereas 34 (10.2%) as FIGO stage II. Of the 24 patients with a clinical stage II cancer, 12 underwent a Radical Hysterectomy with Pelvic Lymph Node Dissection (RH/PLND), of which seven were diagnosed with FIGO stage II. In 72.1% of the patients adjuvant radiation was given or not in adherence to the guidelines. Whether treatment was given according to the guidelines or not did not affect 5 years overall survival. CONCLUSION: This suggests that extensive surgical procedures are redundant in the treatment of occult stage II endometrial cancer.

Maternal and fetal outcome after severe anemia in pregnancy in rural Ghana.

BACKGROUND: Anemia in pregnancy contributes to poor outcome for mother and child in low-income countries. This study analyzes adverse maternal and fetal outcome after severe anemia in pregnancy in rural Ghana. METHODS: A cohort study in two (sub)district hospitals, including 157 pregnant women exposed to severe anemia (Hb < 8.0 g/dl) and 152 nonexposed pregnant women (Hb > or = 10.9 g/dl), matched for age and parity strata. Adverse outcomes analyzed were postpartum hemorrhage, need for blood transfusion, maternal mortality, low birth-weight, and perinatal mortality. RESULTS: Compared to nonexposed women, exposed women had an increased risk of maternal death (5/157 versus 0/152). Fetal outcome did not significantly differ between the study groups, although perinatal mortality was increased with exposure to Hb < 7.0 g/dl (OR 3.1; 95% CI 1.0-9.4), and low birth-weight was increased with exposure to Hb < 6.0 g/dl (OR 2.5; 95% CI 1.2-5.4). Overall fetal outcome was significantly better when hemoglobin prior to childbirth was at least 8.0 g/dl (OR 3.9; 95% CI 1.6-9.6), body mass index at least 20 kg/m2 (OR 2.8; 95% CI 1.5-5.3), and number of antenatal visits at least 4 (OR 2.0; 95%CI 1.1-3.7). CONCLUSIONS: Severe anemia in pregnancy results in relatively poor maternal and fetal outcome. Apparently maternal risks increase prior to fetal risks. In order to improve maternal and fetal outcome, it is recommended that district hospitals in low-income countries make prevention, early diagnosis, and treatment of severe anemia in pregnancy a priority.

A randomized controlled trial of duloxetine alone, pelvic floor muscle training alone, combined treatment and no active treatment in women with stress urinary incontinence.

PURPOSE: We primarily compared the effectiveness of combined pelvic floor muscle training (PFMT) and duloxetine with imitation PFMT and placebo for 12 weeks in women with stress urinary incontinence (SUI). In addition, we compared the effectiveness of combined treatment with single treatments, single treatments with each other and single treatments with no treatment. MATERIALS AND METHODS: This blinded, doubly controlled, randomized trial enrolled 201 women 18 to 75 years old with SUI at 17 incontinence centers in the Netherlands, United Kingdom and United States. Women averaged 2 or more incontinence episodes daily and were randomized to 1 of 4 combinations of 80 mg duloxetine daily, placebo, PFMT and imitation PFMT, including combined treatment (in 52), no active treatment (in 47), PFMT only (in 50) and duloxetine only (in 52). The primary efficacy measure was incontinence episode frequency. Other efficacy variables included the number of continence pads used and the Incontinence Quality of Life questionnaire score. RESULTS: The intent to treat population incontinence episode frequency analysis demonstrated the superiority of duloxetine with or without PFMT compared with no treatment or with PFMT alone. However, pad and Incontinence Quality of Life analyses suggested greater improvement with combined treatment than single treatment. A completer population analysis demonstrated the efficacy of duloxetine with or without PFMT and suggested combined treatment was more effective than either treatment alone. CONCLUSIONS: The data support significant efficacy of combined PFMT and duloxetine in the treatment of women with SUI. We hypothesize that complementary modes of action of duloxetine and PFMT may result in an additive effect of combined treatment.
