To summarize published data about abdominal sacrocolpopexy and to highlight areas about which data are lacking. We conducted a literature search on MEDLINE using Ovid and PubMed, from January,1966 to January, 2004, using search terms "sacropexy," "sacrocolpopexy," "sacral colpopexy," "colpopexy," "sacropexy," "colposacropexy," "abdominal sacrocolpopexy" "pelvic organ prolapse and surgery," and "vaginal vault prolapse or surgery" and included articles with English-language abstracts. We examined reference lists of published articles to identify other articles not found on the electronic search. We examined all studies identified in our search that provided any outcome data on sacrocolpopexy. Because of the substantial heterogeneity of outcome measures and follow-up intervals in case studies, we did not apply meta-analytic techniques to the data. Follow-up duration for most studies ranged from 6 months to 3 years. The success rate, when defined as lack of apical prolapse postoperatively, ranged from 78-100% and when defined as no postoperative prolapse, from 58-100%. The median reoperation rates for pelvic organ prolapse and for stress urinary incontinence in the studies that reported these outcomes were 4.4% (range 0-18.2%) and 4.9% (range 1.2% to 30.9%), respectively. The overall rate of mesh erosion was 3.4% (70 of 2,178). Some reports found more mesh erosions when concomitant total hysterectomy was done, whereas other reports did not. There were no data to either support or refute the contentions that concomitant culdoplasty or paravaginal repair decreased the risk of failure. Most authors recommended burying the graft under the peritoneum to attempt to decrease the risk of bowel obstruction; despite this, the median rate (when reported) of small bowel obstruction requiring surgery was 1.1% (range 0.6% to 8.6%). Few studies rigorously assessed pelvic symptoms, bowel function, or sexual function. Sacrocolpopexy is a reliable procedure that effectively and consistently resolves vaginal vault prolapse. Patients should be counseled about the low, but present risk, of reoperation for prolapse, stress incontinence, and complications. Prospective trials are needed to understand the effect of sacrocolpopexy on functional outcomes.

Our previous study showed that bacterial genomes can be identified using 16S rRNA sequencing in urine specimens of both symptomatic and asymptomatic patients who are culture negative according to standard urine culture protocols. In the present study, we used a modified culture protocol that included plating larger volumes of urine, incubation under varied atmospheric conditions, and prolonged incubation times to demonstrate that many of the organisms identified in urine by 16S rRNA gene sequencing are, in fact, cultivable using an expanded quantitative urine culture (EQUC) protocol. Sixty-five urine specimens (from 41 patients with overactive bladder and 24 controls) were examined using both the standard and EQUC culture techniques. Fifty-two of the 65 urine samples (80%) grew bacterial species using EQUC, while the majority of these (48/52 [92%]) were reported as no growth at 10 3 CFU/ml by the clinical microbiology laboratory using the standard urine culture protocol. Thirty-five different genera and 85 different species were identified by EQUC. The most prevalent genera isolated were Lactobacillus (15%), followed by Corynebacterium (14.2%), Streptococcus (11.9%), Actinomyces (6.9%), and Staphylococcus (6.9%). Other genera commonly isolated include Aerococcus , Gardnerella , Bifidobacterium , and Actinobaculum . Our current study demonstrates that urine contains communities of living bacteria that comprise a resident female urine microbiota.

Bacterial DNA and live bacteria have been detected in human urine in the absence of clinical infection, challenging the prevailing dogma that urine is normally sterile. Urgency urinary incontinence (UUI) is a poorly understood urinary condition characterized by symptoms that overlap urinary infection, including urinary urgency and increased frequency with urinary incontinence. The recent discovery of the urinary microbiome warrants investigation into whether bacteria contribute to UUI. In this study, we used 16S rRNA gene sequencing to classify bacterial DNA and expanded quantitative urine culture (EQUC) techniques to isolate live bacteria in urine collected by using a transurethral catheter from women with UUI and, in comparison, a cohort without UUI. For these cohorts, we demonstrated that the UUI and non-UUI urinary microbiomes differ by group based on both sequence and culture evidences. Compared to the non-UUI microbiome, sequencing experiments revealed that the UUI microbiome was composed of increased Gardnerella and decreased Lactobacillus . Nine genera ( Actinobaculum , Actinomyces , Aerococcus , Arthrobacter , Corynebacterium , Gardnerella , Oligella , Staphylococcus , and Streptococcus ) were more frequently cultured from the UUI cohort. Although Lactobacillus was isolated from both cohorts, distinctions existed at the species level, with Lactobacillus gasseri detected more frequently in the UUI cohort and Lactobacillus crispatus most frequently detected in controls. Combined, these data suggest that potentially important differences exist in the urinary microbiomes of women with and without UUI, which have strong implications in prevention, diagnosis, or treatment of UUI. IMPORTANCE New evidence indicates that the human urinary tract contains microbial communities; however, the role of these communities in urinary health remains to be elucidated. Urgency urinary incontinence (UUI) is a highly prevalent yet poorly understood urinary condition characterized by urgency, frequency, and urinary incontinence. Given the significant overlap of UUI symptoms with those of urinary tract infections, it is possible that UUI may have a microbial component. We compared the urinary microbiomes of women affected by UUI to those of a comparison group without UUI, using both high-throughput sequencing and extended culture techniques. We identified statistically significant differences in the frequency and abundance of bacteria present. These differences suggest a potential role for the urinary microbiome in female urinary health.

Clinical urine specimens are usually considered to be sterile when they do not yield uropathogens using standard clinical cultivation procedures. Our aim was to test if the adult female bladder might contain bacteria that are not identified by these routine procedures. An additional aim was to identify and recommend the appropriate urine collection method for the study of bacterial communities in the female bladder. Consenting participants who were free of known urinary tract infection provided urine samples by voided, transurethral, and/or suprapubic collection methods. The presence of bacteria in these samples was assessed by bacterial culture, light microscopy, and 16S rRNA gene sequencing. Bacteria that are not or cannot be routinely cultivated (hereinafter called uncultivated bacteria) were common in voided urine, urine collected by transurethral catheter (TUC), and urine collected by suprapubic aspirate (SPA), regardless of whether the subjects had urinary symptoms. Voided urine samples contained mixtures of urinary and genital tract bacteria. Communities identified in parallel urine samples collected by TUC and SPA were similar. Uncultivated bacteria are clearly present in the bladders of some women. It remains unclear if these bacteria are viable and/or if their presence is relevant to idiopathic urinary tract conditions.
