Objective: To compare prebundle versus postbundle implementation urinary tract infection (UTI) rates among inpatients within 6 weeks of clean-contaminated pelvic reconstructive surgery. 

Methods:The authors conducted a retrospective cohort study from September 2019 to December 2021 at a tertiary hospital. The bundle strategy included the following: universal preoperative UTI check with treatment if positive, replacing prolonged postoperative voiding trials on the ward with earlier discharge and indwelling catheter removal by a nurse continence advisor the next day, and daily cranberry extract for 6 weeks postoperatively. UTI was defined as positive urine culture (>= 100 000 colony-forming unit per mL) in a symptomatic patient. Data analysis involved hypothesis testing and logistic regression. 

Results: The authors reviewed 132 postbundle inpatient charts and retained 93 for analyses. The results were compared with 204 prebundle inpatient charts. The rate of postoperative UTI decreased from 17.6% in the prebundle group to 6.5% after bundle implementation (P = 0.01). The adjusted odds ratio for postbundle versus prebundle likelihood of UTI was 0.35 (95% confidence interval, 0.13-0.98; P = 0.045). Significantly more postbundle patients compared with prebundle patients were discharged home on the first day postoperatively (76.3% vs. 37.7%, P < 0.001). 

Conclusions: A clinical bundle can significantly decrease both UTI rates and hospital stay after pelvic reconstructive surgery.

Introduction and Hypothesis: Urinary tract infections (UTIs) are a common medical problem and prophylaxis of recurrent UTIs is an ongoing clinical challenge. In the present study we examined whether acupuncture is able to prevent recurrent UTIs in women. 

Methods: This multicentre randomised controlled trial, based at a University clinic and private acupuncture clinics, recruited women suffering from recurrent uncomplicated UTIs. Participants were randomised to the acupuncture group or control group. Acupuncture therapy consisted of 12 treatments over a period of 18 weeks, using a set of predefined body and ear acupuncture points. Cranberry products were recommended to all participants as standard of care.

Results: A total of 137 women were randomised (68 acupuncture, 69 control group) and occurrence of UTIs at 6 and 12 months could be assessed in 123 and 120 women respectively. Acupuncture combined with cranberry slightly increased the proportion of UTI-free women compared with cranberry alone at 6 months (59% vs 46%, p = 0.2). Between 6 and 12 months the proportion of UTI-free women was significantly higher in the acupuncture group (66 vs 45%, p = 0.03). The number of UTIs decreased from baseline to 12 months in both study groups. The number of UTIs at 12 months was significantly lower in the acupuncture group (median difference 1, p = 0.01).

Conclusions: Segmental acupuncture may be an effective treatment option for women with recurrent UTIs over a longer follow-up period and may limit antibiotics use. Further studies are needed.

Urinary tract infections (UTIs) are the most common bacterial infections in postmenopausal women, and women with diabetes are possibly at a higher risk. The aim of this study is to evaluate the potential benefit on the prevention of UTI episodes, assessed by urinalysis and urine culture (primary outcome) after two, four and six months, of daily oral dietary supplement (120 mg highly standardized cranberry extract phytosome), compared to placebo, in diabetic postmenopausal women taking SGLT-2 inhibitors. Forty-six subjects (mean age 72.45 +/- 1.76) completed the study (23 placebo/23 supplement). Considering UTI episodes, during the six-month supplementation period, an increase of 1.321 (95% CI: -0.322; 2.9650) was observed in the placebo group, while it remained at a steady value of 0.393 (95% CI: -4.230; 5.016) in the supplemented group. Regarding UTI episodes, in both groups, interaction between times for supplementation was statistically significant (p = 0.001). In particular, at follow-up 4, 9% of the placebo group showed infection versus only 3% with cranberry supplementation. Glycaemia and glycated hemoglobin values (secondary outcomes) were not modified at the end of six months with respect to the basal values in both groups, as expected. While in terms of quality of life per the SF-12 health questionnaire, there were no differences between the two groups, an improvement in SF-12 quality of life was observed in both groups (six months vs. basal). In conclusion, highly standardized cranberry extract phytosome supplementation reduced UTI recurrence.

Background: Urinary tract infection (UTI) is a renal infection that affects the urinary tract and is global problem related to health and many people are affected each year at some points of their lives. Modern studies about urinary tract infections show that almost one third of the world's population has been suffering from this ailment. Different antibacterial medicines have been reported to have resistance against pathogens. In order to overcome the problem, exploration for new and dynamic antibacterial agents from natural sources is the emerging trend. 

Primary study objective: The primary objective was to evaluate the efficacy and safety of the polyherbal test drug formulation, "Crano-cure", as treatment for UTIs. 

Methods/design: In the current study, clinical trials were designed to evaluate the effects of the polyherbal formulation "Crano-cure" compared to the standard drug Ciprofloxacin in randomized, controlled multicenter trial of 205 patients, analyzing clinical outcomes and safety profiles. 

Setting and participants: Conducted across multiple centers, including Shifa-ul-Mulk Memorial Hospital at Hamdard University Karachi and three other clinics, the study involved 205 patients aged 15-60, irrespective of their socioeconomic status. 

Intervention: Patients were classified into two groups i.e. control group (ciprofloxacin) and the test group (crane-cure). Polyherbal formulation of 500 mg Crano-cure capsules two times in a day were administered to the test group for 28 days. The control group was administered a control ciprofloxacin tablet 500 mg two times in a day for 28 days. 

Primary outcome measures: The drug was found safe for further clinical study after observing changes or improvements in UTI symptoms, urine culture and blood complete tests. The clinical trial was dully registered on the US National Library of Medicine, ClinicalTrials.gov Identifier: NCT04575493. The trial was accompanied in the instructions of EC (Ethical Committee). The study plan and procedures were displayed to the BASR (Board of Advance Studies and Research) and board members of the Ethical Committee (EC), which was ERB-2021-9-1. 

Results: Clinical study results revealed the effectiveness of Crano-cure in the management of UTIs symptoms and hematological and biochemical parameters including blood complete test, liver function tests, renal function tests and lipid profile. Moreover, the test drug Crano-cure revealed a significance level (P ≤ .05) in compliance and cost-effectiveness compared to control ciprofloxacin.

Background: Improving the efficiency of treatment and prevention of recurrent lower urinary tract infection (LUTI) is an important problem in modern urology. A significant role is given to the non-antibiotic measures. 

Aim: To evaluate the clinical and microbiological efficiency of the drug Urolife-Next in patients with recurrent UTI. 

Materials and methods: A total of 70 women with recurrent UTI aged 18 to 55 years (mean 35.1+/-10.1) and symptoms of cystitis were included in the study. After antibacterial therapy, all patients were divided into 3 groups. In the group 1 (n=24), patients took Urolife-Next 1 capsule 3 times a day for 90 days, in the group 2 (n=23) Urolife-Next in the same dose, but for a period of 30 days, while patients of group 3 (n=23) did not receive any treatment. The total follow-up period was 90 days. Frequency and severity of symptoms of recurrent UTI were assessed. The microbiological part of the study included evaluation of the presence and severity of anti-adhesive, anti-biofilm and direct antibacterial effects of the Urolife-Next against uropathogens isolated from urine of patients with exacerbation of UTI. 

Results: In group 1, in which patients took Urolife-Next throughout the study, the lowest frequency of relapses was seen. During the 90-day follow-up, recurrences of UTI occurred in only 3 (12.5%) patients in group 1, compared to 18 (78.3%) in group 3. In addition, in the group 1 there was a significantly lower severity of symptoms during exacerbation of cystitis compared to the initial episode, as well as to 3. Urolife-Next showed antibacterial activity against 29 (41.4%) of 70 strains of uropathogens. The minimum inhibitory concentration of Urolife-Next against gram-negative microorganisms was on average 2 times higher than for gram-positive pathogens. A pronounced anti-adhesive activity of Urolife-Next in vitro was also revealed. The maximum anti-adhesive effect was observed 2 hours after the start of the study. By this time, the adhesion index for cultures in the presence of Urolife-Next was 2.3 times lower than the control values for E. coli, 2.5 times for Kl. pneumoniae, and 2.9 times for E. faecalis. Significant antibiofilm activity of Urolife-Next was also noted. The severity of biofilm formation, which was assessed by changes in the optical density of cultures, decreased by 1.3-2.2 times, depending on the type of uropathogens. 

Conclusions: The results of the study prove the efficiency of the dietary supplement Urolife-Next for the prevention of recurrences in patients with UTI. Its components (D-mannose, cranberry extract, vitamins D and C, hyaluronic acid, probiotics) influence the main pathogenetic factors.

OBJECTIVE: Despite conflicting evidence, it is common practice to use continuous antibiotic prophylaxis (CAP) in patients with indwelling double-J (DJ) stents. Cranberry extracts and d-mannose have been shown to prevent colonization of the urinary tract. We evaluated their role in this setting.METHODS: We conducted a prospective randomized study to evaluate patients with indwelling DJ stents following urological procedures. They were randomized into three groups. Group A (n=46) received CAP (nitrofurantoin 100 mg once daily [OD]). Group B (n=48) received cranberry extract 300 mg and d-mannose 600 mg twice daily (BD). Group C (n=40) received no prophylaxis. The stents were removed between 15 days and 45 days after surgery. Three groups were compared in terms of colonization of stent and urine, stent related symptoms and febrile urinary tract infections (UTIs) during the period of indwelling stent and until 1 week after removal.RESULTS: In Group A, 9 (19.5%) patients had significant bacterial growth on the stents. This was 8 (16.7%) in the Group B and 5 (12.5%) in Group C (p-value: 0.743). However, the culture positivity rate of urine specimens showed a significant difference (p-value: 0.023) with Group B showing least colonization of urine compared to groups A and C. There was no statistically significant difference in the frequency of stent related symptoms (p-value: 0.242) or febrile UTIs (p-value: 0.399) among the groups.CONCLUSION: Prophylactic agents have no role in altering bacterial growth on temporary indwelling DJ stent, stent related symptoms or febrile UTIs. Cranberry extract may reduce the colonization of urinary tract, but its clinical significance needs further evaluation.

In this preliminary pilot registry study, we investigated the effects of the oral supplementation of a standardized cranberry extract (Anthocran R Phytosome R, Indena) delivered by a lecithin-based system, for the prophylactic management of recurrent-urinary tract infections (R-UTIs). We included 64 otherwise healthy subjects who underwent a surgical procedure and required post-surgical urinary catheterization for high-risk UTIs or a previous history of R-UTIs. Patients were given supplementation with the standardized cranberry extract at the dose of either 120 mg/day (n = 12) or 240 mg/day (n = 12) or assigned to a control group consisting of standard management (SM; n = 18) or nitrofurantoin administration (n = 22) for 4 weeks. After 4 weeks, patients receiving the standardized cranberry supplementation reported to have a more effective reduction in UTI symptoms, as assessed on the visual analogue scale, compared with patients in the SM or nitrofurantoin groups. The occurrence of hematuria and urine bacterial contamination were decreased among patients treated with the supplement compared with controls (p < 0.05). The cranberry extract was also superior to the control management in terms of recurrence of signs/symptoms, with none of the patients in this group suffering from a R-UTI in the 3 months following the study end (p < 0.05). The supplementation showed an optimal safety profile, with no significant adverse events and no drop-outs in the supplement group. This registry shows that this cranberry extract is effective as a supplementary, preventive management in preventing post-operative, post-catheter UTIs; the product has a good tolerability profile.

In this paper, an A-type procyanidin (PAC)-rich cranberry extract (CB-B) was obtained mixing different extracts and was formulated with D-mannose and ascorbic acid to obtain a novel nutraceutical (URO-F) aimed at preventing non-complicated bacterial urinary tract infections (UTIs). To assess the bioactivity of CB-B and URO-F, urine samples collected from six healthy volunteers undergoing a 2-days oral consumption of 0.41 g/day of CB-B or 10 g/day of URO-F (corresponding to 72 mg/day of PACs) were tested against uropathogenic E. coli (UPEC) incubated on urinary bladder epithelial cells (T24). Urinary markers of CB-B and URO-F consumption were assessed in the same urine output by UPLC-QTOF-based untargeted metabolomics approach. CB-B and URO-F were evaluated for their ability to promote the intestinal barrier function by restoring the trans-epithelial electrical resistance (TEER) and to inhibit the production of inflammatory cytokines in intestinal epithelial Caco2 cells. CB-B was characterized by a high PAC-A content (70% of total PACs) and a broad distribution of different PACs polymers (dimers-hexamers). Urine from subjects consuming CB-B and URO-F showed a significant effect in reducing the adhesion of UPEC to urothelium in vitro, supporting their efficacy as anti-adhesive agents after oral intake. CB-B inhibited the release of cytokine IL-8, and both products were effective in restoring the TEER. Overall, our results show that the beneficial effects of CB-B and URO-F on UTIs are not only due to the antiadhesive activity of cranberry on UPEC in the urothelium, but also to a multi-target activity involving anti-inflammatory and permeability-enhancing effects on intestinal epithelium.

Objectives: To determine the feasibility of conducting a randomised trial of the effectiveness of cranberry extract in reducing antibiotic use by women with symptoms of acute, uncomplicated urinary tract infection (UTI).Design: Open-label feasibility randomised parallel group trial. Setting: Four general practices in Oxfordshire.Participants: Women aged 18 years and above presenting to general practice with symptoms of acute, uncomplicated UTI.Interventions: Women were randomly assigned using Research Electronic Data Capture in a 1:1:1 ratio to: (1) immediate antibiotics alone (n=15); (2) immediate antibiotics and immediate cranberry capsules for up to 7 days (n=15); or (3) immediate cranberry capsules and delayed antibiotics for self-initiation in case of non-improvement or worsening of symptoms (n=16).Primary and secondary outcome measures: The primary outcome measures were: rate of recruitment of participants; numbers lost to follow-up; proportion of electronic diaries completed by participants; and acceptability of the intervention and study procedures to participants and recruiters. Secondary outcomes included an exploration of differences in symptom burden and antibiotic use between groups. Results: Four general practitioner practices (100%) were opened and recruited participants between 1 July and 2 December 2019, with nine study participants recruited per month on average. 68.7% (46/67) of eligible participants were randomised (target 45) with a mean age of 48.4 years (SD 19.9, range 18-81). 89.1% (41/46) of diaries contained some participant entered data and 69.6% (32/46) were fully complete. Three participants (6.5%) were lost to follow-up and two (4.4%) withdrew. Of women randomly assigned to take antibiotics alone (controls), one-third of respondents reported consuming cranberry products (33.3%, 4/12). There were no serious adverse events.Conclusions: It appears feasible to conduct a randomised trial of the use of cranberry extract in the treatment of acute, uncomplicated UTI in general practice

PURPOSE: Our objective was to assess the efficacy of a high dose cranberry proanthocyanidin extract for the prevention of recurrent urinary tract infection.MATERIAL AND METHODS: We recruited 145 healthy, adult women with a history of recurrent urinary tract infection, defined as >= 2 in the past 6 months or >= 3 in the past 12 months in this randomized, controlled, double-blind clinical trial. Participants were randomized to receive a high dose of standardized, commercially available cranberry proanthocyanidins (2 x 18.5 mg daily, n = 72) or a control low dose (2 x 1 mg daily, n = 73) for a 24-week period. During follow-up, symptomatic women provided urine samples for detection of pyuria and/or bacteriuria and received an appropriate antibiotic prescription. The primary outcome for the trial was the mean number of new symptomatic urinary tract infections during a 24-week intervention period. Secondary outcomes included symptomatic urinary tract infection with pyuria or bacteriuria.RESULTS: In response to the intervention, a non-significant 24% decrease in the number of symptomatic urinary tract infections was observed between groups (Incidence rate ratio 0.76, 95%CI 0.51-1.11). Post-hoc analyses indicated that among 97 women who experienced less than 5 infections in the year preceding enrolment, the high dose was associated with a significant decrease in the number of symptomatic urinary tract infections reported compared to the low dose (age-adjusted incidence rate ratio 0.57, 95%CI 0.33-0.99). No major side effects were reported.CONCLUSION: High dose twice daily proanthocyanidin extract was not associated with a reduction in the number of symptomatic urinary tract infections when compared to a low dose proanthocyanidin extract. Our post-hoc results reveal that this high dose of proanthocyanidins may have a preventive impact on symptomatic urinary tract infection recurrence in women who experienced less than 5 infections per year.TRIAL
