“…Secondly, most of publications (25/29) included in this study were retrospective observational studies, which were considered moderate evidence, and so the conclusions drawn in this analysis were restricted by this study type. Thirdly, significant heterogeneity was observed in the study, which was not surprising as heterogeneity often exists in such meta-analysis of overall prevalence454647. Although subgroup and meta-regression analyses did indicate geographic region, survey year, and percentage of multiparous to explain the observed heterogeneity, the remainder among the studies could be unexplained by the variables examined.…”

Antepartum hemorrhage (APH) is an important cause of perinatal mortality and maternal morbidity in pregnant women with placenta previa in the world. However, the epidemiological characteristics are not completely understood. We performed an initial systematic review and meta-analysis to assess the prevalence of APH in pregnant women with placenta previa. It was totally performed following the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement. PubMed, Elsevier Science Direct, and the Cochrane Library were searched before April 2016. A meta-analysis with a random-effects model based on a proportions approach was performed to determine the prevalence. Stratified analyses, meta-regression method, and sensitivity analysis were utilized to analyze the heterogeneity. A total of 29 articles were included. The pooled overall prevalence of APH among pregnant women with placenta previa was 51.6% (95% CI 42.7–60.6) in a heterogeneous set of studies (I2 = 97.9). Correlation analysis found that there was a positive correlation between prevalence and percentage of multiparous (r = 0.534, P = 0.027) and a negative correlation between prevalence and survey year (r = −0.400, P = 0.031). In conclusion, the prevalence of APH was a high condition among pregnant women with placenta previa.

“…It is highly prevalent in China. The overall prevalence of BPH among men aged over 40 years is about 36.6% (Wang et al, 2015). And this occurrence rate reaches 58.1% and 69.2% for men in their 70s and 80 years or older (Wang et al, 2015).…”

And this occurrence rate reaches 58.1% and 69.2% for men in their 70s and 80 years or older (Wang et al, 2015). Although it is not life-threatening, BPH has substantial negative impact on patients' quality of life and overall health perception (Choi et al, 2014) and brings considerable financial burden on the patients' families and society (Yoshida et al, 2015).…”

Background Prostate volume (PV) and its change rate are important for the progression of prostate disease, but studies on their estimates are inconsistent. Objectives To investigate whether age, prostate‐specific antigen (PSA), and other specific characteristics are associated with PV and its change rate. Materials and Methods A community‐based cohort study was conducted in a rural area of China among male residents aged 40–80 years. PV was estimated at baseline and at 4 years of follow‐up by trans‐abdominal ultrasound. Annual PV change rate (PVCR) was calculated as change in volume divided by time interval. Baseline characteristics, including age, serum PSA, and hormones, were evaluated. And their relationships with PV or PVCR were assessed with Pearson correlation and multivariate linear regression analyses. Results Totally, 462 participants completed the follow‐up with baseline PV (PV0) of 15.6 ± 5.5 ml. PV0 was highly correlated with age and PSA in pairwise correlations (Pearson r = 0.35 and 0.34, respectively, p < 0.01). Multivariate linear regression showed similar associations that PV0 tended to increase with age and PSA. The average PVCR was 0.7 ± 1.8 ml/year. In pairwise correlations, PVCR was inversely correlated with PV0 and positively correlated with PSA, while it was not significantly related to baseline age. Linear regression of PVCR on age and PSA in groups classified by PV0 quartile showed that age was not a significant estimator of PVCR, whereas PSA was. In each PV0 group, PVCR tended to increase with PSA. Discussion and Conclusion PV was positively associated with age and PSA, and it tended to grow faster in men with smaller baseline PV and higher PSA. PSA can be a valuable parameter for estimating both the size and the growth speed of prostate. Although age is associated with prostate enlargement, it does not appear to be related to the longitudinal change rate of PV.

“…In the Chinese study done by Wang et al the occurrence rate of BPH was in age groups of 40-49 years was 2.9%, 50-59 years 29%, 60-69 years 44.7%, 70-79 years 58.1 and 80 years and older was 69.2%. 3 The prevalence rate increases with the age. In a Korean study, there were 2 patients (4.4%) in the 40-49 years group, 18 patients (10.9%) in 50-59 years group, 44 patients (22%) in the age group of 60-69 years group and 56 patients (26.6%) above the age of 70 years.…”

Background: Benign prostatic hyperplasia is one of the most common old age related benign tumor of urinary tract of men. Though now a day the gold standard treatment is only TURP, but this facility is still out of reach for majority of rural population of India. The rate of complications has come down heavily but still complete hemostasis remains a major concern for these patients.Methods: This present study was conducted at the center from March 2014 to December 2016, the aim of present study was to see the effectiveness of bladder packing on blood loss, complications and comfort of patient in the cases of Benign prostatic hyperplasia (BPH) admitted at in patient department of surgery.Results: A Total of 90 cases of BPH (Benign Prostatic Hypertrophy) were operated by Freyer’s suprapubic transvesical prostatectomy. All the patients presented with symptoms of BPH. A detailed clinical history and examination of all patients was recorded and AUA (American Urological Association), International Prostate Symptom Score (IPSS) was calculated. On table clear urine was confirmed with naked eyes and no Foley’s traction was given. After 72 hours of the surgery, pack was removed, saline irrigation was continued for 5 days. The patient was discharged on the 8th post-operative day after removal of stitches.Conclusions: The prostatic fossa packing technique without any traction is effective in control of postoperative bleed, it is an acceptable option where transurethral resection of prostate(TURP) is not available.
