Abstract
BACKGROUND Cyclophosphamide is an alkylating agent associated with significant toxicities, most importantly hemorrhagic cystitis. Many approaches including mesna use were established to reduce this toxicity. However, data on mesna efficacy are conflicting. OBJECTIVE To investigate the incidence of hemorrhagic cystitis in patients receiving cyclophosphamide therapy with or without mesna. METHODS A retrospective chart review was done on all adult patients receiving cyclophosphamide therapy with or without mesna at the King Saud University Medical City. The incidence of hemorrhagic cystitis was recorded. Patients receiving mesna were compared with those not receiving mesna. Data were reported as numbers and percentages, and appropriate statistical tests of association were used. This step was followed by a comprehensive literature review using appropriate keywords in PubMed from the inception of the database until August 2019. All studies of interest were reported. RESULTS A total of 718 patients' medical records were reviewed. The majority of the patients received mesna (n = 433, 60%). The mesna group had a greater incidence of hemorrhagic cystitis (3.5% vs. 0.4%, p < 0.004) and received a significantly larger cumulative dose (3103 ± 1696 vs. 2465 ± 1528, p < 0.001) mg of cyclophosphamide therapy. Our literature review revealed large differences in the conclusions of published trials with highly diverse study designs and populations, emphasizing on the need of large prospective trials to address this topic.Conclusion and relevance: Our study results do not support the use of mesna in preventing hemorrhagic cystitis. We found that the only influential factor in the development of hemorrhagic cystitis was the dose of cyclophosphamide therapy.

[PMID: 31761714 DOI: 10.1016/j.pedneo.2019.10.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 07/30/2019] [Accepted: 10/21/2019] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The 2011 American Academy of Pediatrics clinical practice guideline recommends when to obtain renal and bladder ultrasound (RBUS) and voiding cystourethrography (VCUG) following febrile urinary tract infection (UTI) for children age 2-24 months. However, there is not consensus about when to obtain imaging in neonates. The objective of this study is to evaluate UTI diagnostic criteria along with RBUS and VCUG in neonates admitted to the NICU in the first 3 months of life. METHODS A retrospective electronic medical record review was performed of neonates admitted to Nationwide Children's Hospital system NICUs between January 2010 and December 2014 with UTI as a primary or secondary diagnosis. Urine culture results were evaluated versus established UTI criteria and renal US and VCUG results were compared. RESULTS Of 81 patients with a straight catheterized urine culture obtained, 28 patients met laboratory criteria for diagnosis of UTI and all but 4 had a RBUS. Urine cultures had an equal distribution of Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Coagulase negative staphylococcus. RBUS showed dilation of the collecting system in 37.5% of patients with UTI compared to 41.3% without UTI. VCUG showed vesicourteral reflux (VUR) on 41.7% of those with UTI compared to 34.8% without UTI. For patients with UTI, the sensitivity of RBUS for VUR on VCUG was 60% with CI [0.17, 0.93] and specificity was 43% with CI [0.12, 0.80]. In patients without UTI, sensitivity of RBUS for VUR on VCUG was 63% with CI [0.26, 0.90] and specificity was 71% with CI [0.42, 0.90]. CONCLUSIONS Fewer than half of neonates that were diagnosed clinically with UTI met laboratory criteria for a UTI. Positive urine cultures grew a wide variety of organisms. The sensitivity of renal ultrasound for VUR is only about 60%.

Abstract
PURPOSE We compared demographics, clinical presentation, comorbidities, urinary profiles, and treatment responses between patients with interstitial cystitis/bladder pain syndrome with and without Hunner lesions. MATERIALS AND METHODS We performed a systematic review of the literature in PubMed® in February 2019. Publications were included if they compared data between patients with interstitial cystitis/bladder pain syndrome with and without Hunner lesions, yielding 59 articles. Meta-analysis was performed on a subset of clinical characteristics. RESULTS Meta-analysis showed that patients with interstitial cystitis/bladder pain syndrome with Hunner lesions were significantly older (MD 6.7 years, 95% CI 2.0-11.3, p=0.005), reported higher urinary frequency (MD 3.2 per day, 95% CI 1.1-5.4, p=0.003), nocturia (MD 1.0 per night, 95% CI 0.1-2.0, p=0.034) and Interstitial Cystitis Symptom Index (MD 2.2, 95% CI 1.4-3.0, p <0.001), but lower cystometric bladder capacity (MD -113 ml, 95% CI -164 to -61 ml, p <0.001) compared to those with interstitial cystitis/bladder pain syndrome without Hunner lesions. There were no differences in pain scores (p=0.105), symptom duration (p=0.2) or sex (p=0.83) between the 2 groups. While some studies reported higher rates of comorbid pain syndromes (eg fibromyalgia) among patients without Hunner lesions, overall results were conflicting. Patients with Hunner lesions had higher urinary levels of pro-inflammatory cytokines/chemokines (CXCL10, NGF, IL-6, IL-8, MIF), luminal nitric oxide and responded well to endoscopic treatment of the Hunner lesions (eg fulguration or triamcinolone injection). In comparative studies patients with interstitial cystitis/bladder pain syndrome with Hunner lesions responded better to oral cyclosporine A than those without Hunner lesions. CONCLUSIONS Systematic review and meta-analysis demonstrated significant differences in demographics, clinical presentation, urinary marker profiles, and treatment responses between patients with and without Hunner lesions, suggesting that they may represent 2 distinct clinical phenotypes. Studies are needed to investigate their mechanistic differences.

Abstract
OBJECTIVE To evaluate the clinical value of endoscopic fibrin glue (FG) application therapy in treating hemorrhagic radiation cystitis (HRC). PATIENTS AND METHODS This is a single-cohort, prospective pilot study. We collected data from patients with HRC who were treated at our urology unit from May 2014 to December 2016. Patients with grade ≥2 HRC for whom conventional therapy and transurethral endoscopic electrocoagulation had failed were treated with endoscopic intravesical FG. The mean follow-up was 26.2 ± 9.78 months. Our analysis included data on patient demographics, pelvic malignancies, radiotherapy regimens, total dose of radiation received, time of onset and severity of hematuria, and previous intravesical management. Following FG intervention, patients' clinical status was defined as: (1) clinical response; absence of dysuria, urgency, and frequency; discontinuation of analgesic medication; and Foley catheter removal, but with ongoing hematuria grade <2; (2) complete response, clinical response, and no further hematuria; or (3) no response, no clinical response, and sustained hematuria. RESULTS A total of 20 patients (12 women and 8 men; mean age, 69 ± 7.5 years) were treated with 12 mL FG intravesically, using endoscopic application. Of the 20 patients, 16 (80%) had a complete response and 4 (20%) had a clinical response. In the case of four patients (20%), treatment was carried out twice. Mean hospital stay was 6 ± 2.5 days. The intervention showed good tolerability in all patients. No major adverse events were reported. Bladder spasms were the only minor adverse events reported in six patients (30%). CONCLUSION Application of FG is an effective, practical, affordable, and repeatable procedure for the treatment of grade ≥2 HRC.

Abstract
AIMS Ketamine is a general anesthetic. Dissociative effects and low cost led ketamine becoming an illegal recreational drug in young adults. Ketamine-induced uropathy (KIU) is one of the complications observed in abusers. This study aimed to provide a systematic literature review on KIU clinical presentation, pathophysiology, and treatments. METHODS We performed the literature search in PubMed, Web of Science, Scopus, and Embase using the terms ketamine and bladder. English papers on human and animal studies were accepted. RESULTS A total of 75 papers were selected. Regular ketamine users complain about severe storage symptoms and pelvic pain. Hydronephrosis may develop in long-term abusers and is correlated to the contracted bladder, ureteral stenosis, or vesicoureteral reflux due to ureteral involvement and/or bladder fibrosis. Cystoscopy shows ulcerative cystitis. Ketamine in urine might exert direct toxicity to the urothelium, disrupting its barrier function and enhancing cell apoptosis. The presence of ketamine/ions in the bladder wall result in neurogenic/IgE-mediated inflammation, stimulation of the inducible nitric oxide synthase-cytokines-cyclooxygenase pathway with persistent inflammation and fibrosis. Abstinence is the first therapeutic step. Anti-inflammatory drugs, analgesics and anticholinergics, intravesical instillation of hyaluronic acid, hydrodistension and intravesical injection of botulin toxin-A were helpful in patients with early-stage KIU. In patients with end-stage disease, the control of intractable symptoms and the increase of bladder capacity were the main recommendations to perform augmentation enterocystoplasty. CONCLUSIONS KIU is becoming a worldwide health concern, which should be taken into account in the differential diagnosis of ulcerative cystitis.

Abstract
BACKGROUND Acute uncomplicated cystitis is one of the most common diagnoses for which antibiotic treatment is prescribed in the outpatient setting. Despite the availability of national guidelines, there remains a wide pattern in prescriber choices for therapy. Recent data portray a picture of consistently longer durations than recommended prescribed in outpatient settings. OBJECTIVE The objective was to evaluate the effect of a system-based intervention on adherence to guideline-recommended durations of therapy for uncomplicated cystitis in the outpatient setting. METHODS This quasi-experimental study included women aged 18-64 years who were seen at five family medicine clinics at an academic medical centre and were prescribed targeted antibiotics for uncomplicated cystitis (nitrofurantoin monohydrate/macrocrystals 100 mg, trimethoprim-sulfamethoxazole 160/800 mg or ciprofloxacin 250 mg). The intervention involved revising or adding pre-filled, but modifiable, default prescribing instructions in the electronic health record (EHR) for the targeted antibiotics. We evaluated adherence to guideline-recommended duration of therapy as well as days of therapy (DOT) before and after the intervention. RESULTS A total of 787 pre-intervention and 862 post-intervention cases were included. Adherence to recommended duration of therapy increased from 29.4% to 76.3% (P < 0.01). The average DOT decreased by 23% from 6.6 to 5.1 (P < 0.01). CONCLUSION A stewardship intervention consisting of revising/adding default prescribing instructions to targeted antimicrobials in an EHR was associated with increased adherence to recommended durations of therapy for uncomplicated cystitis and reduction of unnecessary antibiotic exposure. More studies are needed to confirm effectiveness across multiple medical record platforms.

Abstract
Acute Cystitis Symptom Score (ACSS) is an 18-item self-reporting questionnaire for clinical diagnosis and follow-up of acute uncomplicated cystitis (AUC) in women. The ACSS, originally developed in Uzbek and Russian languages, is now available in several languages. The purpose of the study was to validate the ACSS questionnaire in the Italian language. Linguistic validation was carried out according to Linguistic Validation Manual for Patient-Reported Outcomes Instruments guidelines. Clinical validation was carried out by enrolling one hundred Italian-speaking women. All women were asked to fill in the ACSS questionnaire during their medical visit. Fifty-four women, median age 36 (Inter Quartile Range 28-49), were diagnosed with AUC, while 46 women, median age 38 (IQR 29-45), were enrolled as the control group attending the hospital's fertility center for couples. The most frequently isolated pathogen in AUC was Escherichia coli (40; 74.0%) followed by Enterococcus faecalis (7; 13.0%) and Staphylococcus saprophyticus (3; 5.6%). Receiver operating characteristic (ROC) curve analysis performed at the first diagnostic visit on a typical symptoms domain cut-off score of 6 revealed a sensitivity of 92.5% and specificity of 97.8%. The Italian version of the ACSS has proved to be a reliable tool with a high accuracy in diagnosis and follow-up in women with AUC. The ACSS may also be useful for clinical and epidemiological studies.

Abstract
INTRODUCTION Differentiating between a urinary tract infection and asymptomatic bacteriuria is an important distinction to make, especially in noncommunicative patients. An algorithm meant to aid in the diagnosis and treatment of urinary tract infections in this population was implemented within a psychiatric emergency department in January 2019. The primary objective of this project was to assess the impact of the algorithm (the intervention) regarding symptom documentation and antibiotic use. Secondary objectives included assessing changes in inappropriate prescribing and urine culture orders. METHODS Preintervention outcomes were measured from August 1, 2018, through November 30, 2018, while the postintervention cohort included patients admitted after January 31, 2019 and discharged before June 1, 2019. Adults admitted to psychiatry with a urinalysis ordered in the emergency department and an ICD-10 code representing dementia, delirium, autism spectrum disorder, or intellectual disability were included; pregnant patients were excluded. RESULTS The preintervention (n = 56) and postintervention (n = 34) cohorts were well balanced with an average age of 66.5 and 70 years, respectively. Neurocognitive disorder was the diagnosis for inclusion in approximately two-thirds of both groups. Numerically, postalgorithm implementation, symptoms were documented more frequently (20.6% vs 10.7%, P = .23) and antibiotics used less often (2.9% vs 14.3%, P = .15). Inappropriate prescribing occurred in 12.5% of preintervention cohort compared to no patients postintervention (P = .04). DISCUSSION The creation and implementation of an algorithm assisting in the diagnosis and treatment of urinary tract infections in noncommunicative patients was associated with a trend toward increased symptom documentation and decreased overall antibiotic use, and significantly increased appropriate antibiotic prescribing.

Abstract
A 23-year-old Korean woman with a residence history in Kenya and Malawi for about 2 years presented with gross hematuria for 1 month. Blood tests were within normal range except eosinophilia. Asymmetrically diffuse wall thickening and calcification were observed at the urinary bladder on CT. Multiple erythematous nodular lesions were observed in the cystoscopy and transurethral resection was done. Numerous eggs of Schistosoma haematobium with granulomatous inflammation were observed in the submucosal layer of the bladder. The patient was diagnosed with schistosomiasis-related cystitis and treated with praziquantel (40 mg/kg/day) twice before and after transurethral resection. This case suggests that S. haematobium infection should be considered as a cause of hematuria in Korea when the patient had a history of traveling endemic areas of schistosomiasis.

Abstract
Enterohemorrhagic Escherichia coli (EHEC), a pathogenic subset of Shiga toxin-producing E. coli (STEC), is an important cause of hemorrhagic colitis and hemolytic–uremic syndrome (HUS), and a rare cause of urinary tract infections (UTIs) with associated HUS. EHEC strains attach intimately to intestinal epithelium with formation of actin pedestals (attaching-effacing (A/E) lesions); however, the mechanism of EHEC attachment to the uroepithelium is unknown. We conducted a retrospective study on archived urinary bladder specimens from gnotobiotic piglets that naturally developed cystitis associated with EHEC O157:H7 infection following oral inoculation and fecal shedding. Paraffin-embedded bladder tissues from three piglets with cystitis and immunohistochemical evidence of EHEC O157:H7 adherence to the uroepithelium were processed for and examined by transmission electron microscopy. EHEC O157:H7 bacteria were found in one of three piglets, intimately attached to pedestals on the apical surfaces of the superficial urothelium (umbrella cells). Cystitis was significantly associated with the length of survival of the piglets post-inoculation (p = 0.0339; estimated odds ratio = 2.6652). This is the first report of E. coli causing A/E-like lesions in the uroepithelium, and also evidence of the utility of the gnotobiotic piglet as a model for studies of the pathogenesis of EHEC UTIs.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a common chronic pelvic disorder with sensory symptoms of urinary urgency, frequency, and pain, indicating a key role for hypersensitivity of bladder-innervating sensory neurons. The inflammatory mast cell mediator histamine has long been implicated in IC/BPS, yet the direct interactions between histamine and bladder afferents remain unclear. In the present study, we show, using a mouse ex vivo bladder afferent preparation, that intravesical histamine enhanced the mechanosensitivity of subpopulations of afferents to bladder distension. Histamine also recruited "silent afferents" that were previously unresponsive to bladder distension. Furthermore, in vivo intravesical histamine enhanced activation of dorsal horn neurons within the lumbosacral spinal cord, indicating increased afferent signaling in the central nervous system. Quantitative RT-PCR revealed significant expression of histamine receptor subtypes (Hrh1-Hrh3) in mouse lumbosacral dorsal root ganglia (DRG), bladder detrusor smooth muscle, mucosa, and isolated urothelial cells. In DRG, Hrh1 was the most abundantly expressed. Acute histamine exposure evoked Ca2+ influx in select populations of DRG neurons but did not elicit calcium transients in isolated primary urothelial cells. Histamine-induced mechanical hypersensitivity ex vivo was abolished in the presence of the histamine H1 receptor antagonist pyrilamine and was not present in preparations from mice lacking transient receptor potential vanilloid 1 (TRPV1). Together, these results indicate that histamine enhances the sensitivity of bladder afferents to distension via interactions with histamine H1 receptor and TRPV1. This hypersensitivity translates to increased sensory input and activation in the spinal cord, which may underlie the symptoms of bladder hypersensitivity and pain experienced in IC/BPS.

Abstract
Today, monotherapy is the most common pharmacological treatment option for patients suffering from overactive bladder (OAB). Recent reports have indicated potential benefits of combination therapy, using a muscarinic antagonist and a β3 -adrenoceptor agonist. This may be of particular interest for therapy-resistant patients with OAB and concomitant cystitis. The objective of the current study was to assess how combination therapy affects bladder parameters in health and cystitis and if the efficacy of the drugs can be linked to altered release of nitric oxide (NO). Rats were pretreated with either a combination of the muscarinic antagonist tolterodine and β3 -selective adrenoceptor agonist mirabegron or saline for 10 days. Forty-eight hours prior to assessing micturition parameters in a metabolic cage, the rats were intraperitoneally injected with cyclophosphamide, causing cystitis, or saline. Urine samples were collected and analyzed for NO content. Bladder contractile properties were assessed in an organ bath setup. Induction of cystitis led to bladder overactivity. Combination therapy normalized bladder parameters. Both induction of cystitis and drug treatment increased the release of NO. The innate contractile properties of the bladder were unaffected by combination therapy. This study demonstrates positive effects of combination drug therapy on symptoms of OAB, possibly indicating it to be a good option for treatment of OAB during concomitant cystitis. It remains to be determined if increased release of NO is crucial for successful pharmacological treatment of bladder overactivity during cystitis.

Abstract
BACKGROUND Urinary Tract Infection (UTI) is a common infection in children. Prompt diagnosis and appropriate treatment are very important to reduce the morbidity associated with this condition. OBJECTIVE To provide an update on the evaluation, diagnosis, and treatment of urinary tract infection in children. METHODS A PubMed search was completed in clinical queries using the key terms "urinary tract infection", "pyelonephritis" OR "cystitis". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature and the pediatric age group. Patents were searched using the key terms "urinary tract infection" "pyelonephritis" OR "cystitis" from www.google.com/patents, http://espacenet.com, and www.freepatentsonline.com. RESULTS Escherichia coli accounts for 80 to 90% of UTI in children. The symptoms and signs are nonspecific throughout infancy. Unexplained fever is the most common symptom of UTI during the first two years of life. After the second year of life, symptoms and signs of pyelonephritis include fever, chills, rigor, flank pain, and costovertebral angle tenderness. Lower tract symptoms and signs include suprapubic pain, dysuria, urinary frequency, urgency, cloudy urine, malodorous urine, and suprapubic tenderness. A urinalysis and urine culture should be performed when UTI is suspected. In the work-up of children with UTI, physicians must judiciously utilize imaging studies to minimize exposure of children to radiation. While waiting for the culture results, prompt antibiotic therapy is indicated for symptomatic UTI based on clinical findings and positive urinalysis to eradicate the infection and improve clinical outcome. The choice of antibiotics should take into consideration local data on antibiotic resistance patterns. Recent patents related to the management of UTI are discussed. CONCLUSION Currently, a second or third generation cephalosporin and amoxicillin-clavulanate are drugs of choice in the treatment of acute uncomplicated UTI. Parenteral antibiotic therapy is recommended for infants ≤ 2 months and any child who is toxic-looking, hemodynamically unstable, immunocompromised, unable to tolerate oral medication, or not responding to oral medication. A combination of intravenous ampicillin and intravenous/intramuscular gentamycin or a third-generation cephalosporin can be used in those situations. Routine antimicrobial prophylaxis is rarely justified, but continuous antimicrobial prophylaxis should be considered for children with frequent febrile UTI.

Abstract
The Argentine Society of Infectious Diseases and other scientific societies have updated these recommendations based on data on urinary tract infections in adults obtained from a prospective multicenter study conducted in Argentina during 2016-2017. Asymptomatic bacteriuria should be treated only in pregnant women, who should also be systematically investigated; the antibiotics of choice are nitrofurantoin, amoxicillin, clavulanic/amoxicillin, cephalexin and trimethoprim-sulfamethoxazole. In procedures involving injury to the urinary tract with bleeding, it is recommended to request urine culture and, in the presence of bacteriuria, antimicrobial treatment according to sensitivity should be prescribed from immediately before up to 24 hours after the intervention. In women, cystitis can be treated with nitrofurantoin, cephalexin or fosfomycin, while trimethoprim-sulfamethoxazole and fluoroquinolones are not recommended; pyelonephritis can be treated with ciprofloxacin, cefixime or cephalexin in ambulatory women or ceftriaxone, cefazolin or amikacin in those who are hospitalized. In men, urinary tract infections are always considered complicated; nitrofurantoin or cephalexin are recommended for 7 days, alternatively fosfomycin should be given in a single dose. In men, ciprofloxacin, ceftriaxone or cefixime are suggested for pyelonephritis on ambulatory treatment whereas ceftriaxone or amikacin are recommended for hospitalized patients. Acute bacterial prostatitis can be treated with ceftriaxone or gentamicin. Fluoroquinolones were the choice treatment for chronic bacterial prostatitis until recently; they are no longer recommended due to the increasing resistance and recent concerns regarding the safety of these drugs; alternative antibiotics such as fosfomycin are to be considered.

Abstract
Recent breakthroughs demonstrate that peripheral diseases can trigger inflammation in the brain, causing psychosocial maladies, including depression. While few direct studies have been made, anecdotal reports associate urological disorders with mental dysfunction. Thus, we investigated if insults targeted at the bladder might elicit behavioral alterations. Moreover, the mechanism of neuroinflammation elicited by other peripheral diseases involves the NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome, which is present in microglia in the brain and cleaves and activates proinflammatory cytokines such as IL-1β. Thus, we further explored the importance of NLRP3 in behavioral and neuroinflammatory changes. Here, we used the well-studied cyclophosphamide (CP)-treated rat model. Importantly, CP and its metabolites do not cross the blood-brain barrier or trigger inflammation in the gut, so that any neuroinflammation is likely secondary to bladder injury. We found that CP triggered an increase in inflammasome activity (caspase-1 activity) in the hippocampus but not in the pons. Evans blue extravasation demonstrated breakdown of the blood-brain barrier in the hippocampal region and activated microglia were present in the fascia dentata. Both changes were dependent on NLRP3 activation and prevented with 2-mercaptoethane sulfonate sodium (Mesna), which masks the effects of the CP metabolite acrolein in the urine. Finally, CP-treated rats displayed depressive symptoms that were prevented by NLRP3 inhibition or treatment with Mesna or an antidepressant. Thus, we conclude that CP-induced cystitis causes NLRP3-dependent hippocampal inflammation leading to depression symptoms in rats. This study proposes the first-ever causative explanation of the previously anecdotal link between benign bladder disorders and mood disorders.

Abstract
WHAT IS KNOWN AND OBJECTIVE Despite recommendations to avoid fluoroquinolones (FQs) as a first-line treatment for uncomplicated cystitis, recent data suggest that FQs remain widely prescribed. Therefore, the objectives of this study were to evaluate the appropriateness of empiric FQ use compared to nitrofurantoin for uncomplicated cystitis and to determine whether there are any trends or predictors of empiric FQ versus nitrofurantoin use for uncomplicated cystitis. METHODS This retrospective study included women ages 19-64 years who were seen at five family medicine clinics and were prescribed targeted antibiotics (nitrofurantoin, ciprofloxacin or levofloxacin) for uncomplicated cystitis. Charts were reviewed to collect data, including symptoms, comorbidities, allergies, creatinine clearance, recent antibiotic use and urine culture data. Appropriateness of empiric selection was determined based on national guidelines and local susceptibility data. RESULTS AND DISCUSSION A total of 677 patient encounters were screened for inclusion. Of those, 567 met the inclusion criteria: 395 nitrofurantoin and 172 FQs. Treatment was considered appropriate in 86.8% and 10.5% of cases that were prescribed nitrofurantoin and FQs, respectively (P < .01). There were four independent predictors of FQ use identified by multivariate logistical regression: clinic at which the patient was treated, age, nitrofurantoin use within 90 days prior to encounter and previous urine culture within one year with an organism non-susceptible to nitrofurantoin. WHAT IS NEW AND CONCLUSION Despite recommendations against FQs for uncomplicated cystitis, they continue to be widely prescribed, and their use for this indication is often inappropriate. This highlights the need for additional interventions and education to improve use and preserve the utility of FQs.

Abstract
AIM To determine whether fosfomycin can be used in treatment of women with acute uncomplicated cystitis in the postpartum period. MATERIALS AND METHODS The results of treatment of acute uncomplicated cystitis in 51 patients in the postpartum period were retrospectively evaluated. All patients received a single dose 3 g of fosfomycin. RESULTS In order to determine clinical efficiency, in all cases laboratory tests were performed prior to and 3 days after treatment. A degree of pain syndrome, the number of voids and urgent episodes were also evaluated. Urine culture was studied before and 7 days after taking fosfomycin. There was a decrease in the number of leukocytes and erythrocytes in urine, number of voids, including urgent episodes. A normalization of urine flora after a single dose of the fosfomycin was noted. DISCUSSION In our research in the repeated analysis of urine culture, the number of bacteria was lower than 104 in all cases, and there was also decrease in the number of voids and intensity of pain syndrome. CONCLUSION The treatment of acute uncomplicated cystitis in women in the early postpartum period has its own characteristics. A single dose of fosfomycin allows to avoid long-term use of the antibiotic and to continue breastfeeding, which is required for the treatment of this disease in lactating women. One of the medicine used in AAC is Fosfomycin Esparma, which has a high safety profile. The use of high-quality antibacterial therapy in these patients to give possibility to avoid complications.

Abstract
AIMS To determine whether glycosaminoglycan (GAG) replenishment is able to improve recovery of a deficient urothelial barrier, chondroitin sulfate (CS) instillations were tested using an in vitro model. Porcine urothelial cells (Ucells) were terminally differentiated in culture conditions to construct a urothelial layer with a functional barrier. This layer was damaged to compromise barrier function to simulate a key characteristic of bladder pain syndrome/interstitial cystitis. The functional effect of subsequent treatment with CS was evaluated. METHODS Primary porcine Ucells were isolated and cultured on inserts. Differentiation of cells was evaluated with immunohistochemical analysis for the presence of umbrella cells, tight junctions and CS. Transepithelial electrical resistance (TEER) measurements were performed to evaluate barrier function. Protamine was used to simulate mild urothelial damage. CS 0.2% (vol/vol), a GAG, was subsequently instilled in the treatment group. The recovery of barrier function was further evaluated with TEER measurements. The Student t test was used for the analysis of results. RESULTS After induction of differentiation, the Ucells expressed barrier markers and a functional barrier was established (measured by high TEER). TEER decreased significantly after instillation with protamine. CS instillation improved recovery of TEER significantly measured after 7 hours (84% vs 22% in controls). After 24 hours; however, the TEER was comparable in both experimental groups. CONCLUSION CS instillation improves the recovery of the urothelial barrier after damage in vitro. This functional experiment shows that CS improves recovery of damaged urothelial function, which supports the hypothesis behind the mechanism of action of GAG-replenishment therapy.

Abstract
Urinary tract infection (UTI) is the most common bacterial infectious disease with a high frequency of recurrence and the leading cause of septicemia. In vivo experimentation has contributed significantly to the present-day knowledge on UTI pathogenesis. This research has traditionally been based on murine models of UTI. Occasional conflicting results between UTI in mice and humans and increasing skepticism toward small rodent models in general warrant the need of novel large-animal infection models that better resemble the anatomy and physiology of humans, and thus better mimic the course of infection in humans. Here, we report, to our knowledge, the first large-animal model of cystitis. The model is based on pigs, and the protocol supports the establishment of persistent, non-ascending infection in this animal and is established without invasive surgical procedures, pain, and discomfort for the animal. The course of infection is monitored by cystoscopy, microscopy of bladder biopsies, and biochemical analysis of urine and blood samples. At termination, harvested whole bladders from infected pigs are analyzed for microbiological colonization using microscopy, histology, and viable bacterial counts. The model is a useful tool in future studies of UTI pathogenesis and opens up novel possibilities to bridge the current knowledge obtained from small-animal UTI models to UTI pathogenesis in humans.

Abstract
PURPOSE Cannabinoids have been shown to exert analgesic and anti-inflammatory effects, and the effects of cannabinoids are mediated primarily by cannabinoid receptors 1 and 2 (CB1 and CB2). The objective of this study was to determine efficacy and mechanism of CB2 activation on cyclophosphamide (CYP)-induced cystitis in vivo. METHODS Cystitis was induced by intraperitoneal (IP) injection of CYP in female C57BL/6J mice. Mice were pretreated with CB2 agonist JWH-133 (1 mg/kg, intraperitoneally), CB2 antagonist AM-630 (1 mg/kg, intraperitoneally) or autophagy inhibitor 3-methyladenine (3-MA) (50 mM, intraperitoneally) before IP injection of CYP. Peripheral nociception and spontaneous voiding were investigated in these mice. Bladders were collected, weighed, and processed for real-time polymerase chain reaction, immunoblotting analysis, histological and immunohistochemical analysis. RESULTS Twenty-four hours after IP injection of CYP, the bladder of CYP-treated mice showed histological evidence of inflammation. The expression of CB2 in bladder was significantly increased in CYP-treated mice. Mechanical sensitivity was significantly increased in CYP-treated mice and CB2 agonist JWH-133 attenuated this effect (P < .05). The number of urine spots was significantly increased after CYP treatment and it was decreased in JWH-133 treated mice (P < .05). Activating CB2 with JWH-133 significantly alleviated bladder tissue inflammatory responses and oxidative stress induced by CYP. Activation of CB2 by JWH-133 increased the expression of LC3-II/LC3-I ratio, and decreased the expression of SQSTM1/p62 in the bladder of cystitis mice, whereas AM-630 induced inverse effects. Further study indicated that JWH-133 could promote autophagy and blocking autophagy by 3-MA dismissed the effort of CB2 in alleviating bladder tissue inflammatory responses and oxidative stress injury. Furthermore, treatment with 3-MA decreased the expression of p-AMPK and induced the phosphorylation of mTOR in the presence of JWH-133 stimulation in cystitis model. CONCLUSIONS Activation of CB2 decreased severity of CYP-induced cystitis and ameliorated bladder inflammation. CB2 activation is protective in cystitis through the activation of autophagy and AMPK-mTOR pathway may be involved in the initiation of autophagy.

Abstract
The World Health Organization has recommended herbal medicine for treatment and control of recurrent cystitis. This study was conducted to determine effect of eshnan on the prevention of recurrent cystitis. The present triple-blind clinical trial was conducted on 126 women (63 women per group) with recurrent cystitis. The participants were assigned to the intervention and control groups. Three 500-mg eshnan or placebo tablets were taken orally with a glass full of water by the participants half an hour after each meal for 2 months. The study subjects were clinically and paraclinically evaluated by the end of the second, fourth, and sixth months after the intervention and every time they showed clinical symptoms of cystitis. The present findings showed that the incidence rate of cystitis and symptoms of cystitis was significantly lower in the eshnan group compared with the placebo group 2, 4, and 6 months after the intervention (p < .05). The incidence of recurrent was also significantly lower in the intervention group compared with the control group (p < .001). No side effects were observed in the intervention and control groups. The consumption of eshnan can improve the symptoms of cystitis and prevent the incidence of recurrent cystitis in women of reproductive age.

Abstract
PURPOSE We performed a systematic review and meta-analysis to compare the effectiveness and safety profile of fosfomycin vs comparator antibiotics in women with acute uncomplicated cystitis. MATERIALS AND METHODS Relevant databases were searched using methods recommended by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. We assessed the risk of bias and confounders. The study primary end point was clinical or microbiological success, defined as complete (cure) and/or incomplete resolution of symptoms at the end of treatment (improvement) and/or microbiological eradication. RESULTS After screening 539 articles 15 were included which recruited a total of 2,295 adult female patients. Of the studies 14 were used for microbiological eradication analysis. We used 11 of the 15 articles in a total of 1,976 patients for clinical resolution and 11 in a total of 1,816 patients for safety outcome analysis. No difference was found for clinical resolution in all comparators combined in 11 randomized controlled trials in a total of 1,976 patients (OR 1.16, 95% CI 0.91-1.49, p=0.13). No difference was found for microbiological eradication in 14 randomized controlled trials in a total of 2,052 patients (OR 1.03, 95% CI 0.83-1.30, p=0.09) or for safety outcome in 11 randomized controlled trials in a total of 1,816 patients (OR 1.17, 95% CI 0.86-1.58, p=0.33). Most adverse effects reported for fosfomycin were transient and single dose therapy seems to have resulted in better patient compliance. CONCLUSIONS Single dose oral fosfomycin trometamol is equal to comparator regimens in terms of clinical and microbiological effectiveness and safety in women with microbiologically confirmed and/or clinically suspected, acute uncomplicated cystitis. It is associated with high patient compliance.

Abstract
Urinary tract infections (UTIs) caused by antibiotic-resistant Gram-negative bacteria are a growing concern due to limited treatment options. Knowledge of the common uropathogens in addition to local susceptibility patterns is essential in determining appropriate empiric antibiotic therapy of UTIs. The recommended first-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is a 5-day course of nitrofurantoin, a 3-g single dose of fosfomycin tromethamine, or a 5-day course of pivmecillinam. High rates of resistance for trimethoprim-sulfamethoxazole and ciprofloxacin preclude their use as empiric treatment of UTIs in several communities, particularly if patients who were recently exposed to them or in patients who are at risk of infections with extended-spectrum β-lactamases (ESBLs)-producing Enterobacteriales. Second-line options include oral cephalosporins such as cephalexin or cefixime, fluoroquinolones and β-lactams, such as amoxicillin-clavulanate. Current treatment options for UTIs due to AmpC- β -lactamase-producing Enterobacteriales include nitrofurantoin, fosfomycin, pivmecillinam, fluoroquinolones, cefepime, piperacillin-tazobactam and carbapenems. Treatment oral options for UTIs due to ESBLs-E coli include nitrofurantoin, fosfomycin, pivmecillinam, amoxicillin-clavulanate, finafloxacin, and sitafloxacin while pivmecillinam, fosfomycin, finafloxacin, and sitafloxacin are treatment oral options for ESBLs- Klebsiella pneumoniae. Parenteral treatment options for UTIs due to ESBLs-producing Enterobacteriales include piperacillin-tazobactam (for ESBL-E coli only), carbapenems including meropenem/vaborbactam, imipenem/cilastatin-relebactam, and sulopenem, ceftazidime-avibactam, ceftolozane-tazobactam, aminoglycosides including plazomicin, cefiderocol, fosfomycin, sitafloxacin, and finafloxacin. Ceftazidime-avibactam, meropenem/vaborbactam, imipenem/cilastatin-relebactam, colistin, fosfomycin, aztreonam and ceftazidime-avibactam, aztreonam and amoxicillin-clavulanate, aminoglycosides including plazomicin, cefiderocol, tigecycline are treatment options for UTIs caused by carbapenem-resistant Enterobacteriales (CRE). Treatment options for UTIs caused by multidrug resistant (MDR)-Pseudomonas spp. include fluoroquinolones, ceftazidime, cefepime, piperacillin-tazobactam, carbapenems including imipenem-cilastatin/relebactam, meropenem, and fosfomycin, ceftolozane-tazobactam, ceftazidime-avibactam, aminoglycosides including plazomicin, aztreonam and ceftazidime-avibactam, cefiderocol, and colistin. It is important to use the new antimicrobials wisely for treatment of UTIs caused by MDR-organisms to avoid resistance development.

Abstract
We performed a comprehensive systematic review of acute pyelonephritis in pregnancy using PubMed, SCOPUS, ClinicalTrials.gov, and Ovid from inception to April 2018. About 7796 references were screened for inclusion, and 52 references from 1908 to 2017 were included. One hundred seven cases of acute pyelonephritis in pregnant women were reviewed. Gestational age at diagnosis was reported as 2 (2%), 43 (40%), and 51 (52%) during the first, second, and third trimesters, respectively. Maternal complications included sepsis (49%), acute respiratory distress syndrome (47%), anaemia (33%), acute kidney injury (10%), renal abscess (6%), and death (6%). 25 preterm deliveries (23%), 6 intrauterine foetal demises (6%), 4 spontaneous abortions (4%), and 8 neonatal intensive care unit admissions (7%) were reported. Microorganisms cultured included Escherichia coli (51%), Klebsiella (8%), Proteus (5%), Staphylococcus aureus (5%), Streptococcus (4%), and Enterococcus (3%). Early diagnosis and management led to fewer complications.Impact statementWhat is already known on this subject? Acute pyelonephritis during pregnancy can lead to adverse pregnancy outcomes and in this article, we highlight the most common outcomes previously reported. Previous studies have reported maternal adverse outcomes and only very few stressed on fetal/neonatal outcomes.What do the results of this study add? The results add that not only is maternal morbidity/mortality is increased, but also increases adverse outcomes for the fetus/neonate, such as preterm delivery and fetal/neonatal demise.What are the implications of these findings for clinical practice and/or further research? The implications from this article serve to increase a medical providers knowledge on how to appropriately counsel pregnant women with acute pyelonephritis. In addition, future research can aim to understand why pregnant women are more prone to morbidity and mortality compared to nonpregnant women.

Abstract
A solving diagnostic and therapeutic problems in patients with various urologic diseases often requires a cooperation between different specialists which emphasizes the interdisciplinarity of our discipline. A number of clinical manifestations and diseases that urologists have to deal with and in which they definitely need a timely assistance from other specialists are described in the article. Determining the connecting links in the work of different specialists, we tried to recall the main " intersection points" and draw attention to the necessary cooperation.
