Urinary tract infections (UTIs) are common infectious diseases that can be associated with substantial morbidity and significant expenditures. This review highlights the current concepts and recent advances in our understanding and management of this condition. Specific topics include pathogenesis, host factors, antimicrobial resistance, recurrent UTIs in women, diagnosis, treatment of uncomplicated and complicated UTIs, prophylaxis, catheter associated bacteriuria, pregnancy, diabetes, UTIs in men, prostatitis, and the chronic pelvic pain syndrome. UTIs can be viewed as an interaction between specific bacterial virulence factors and the patient. A new model explaining the pathogenesis of recurrent UTIs has been presented. There is a need to reconsider traditional treatment recommendations in the face of local resistance patterns, as well as the need to make better use of drugs that are currently available. Prospects for prevention of recurrent UTI include natural compounds, bacterial interference and immunization. With regard to UTI risk in women, patients can be classified based on age, and functional and hormonal status. Appropriate treatment approaches must be based on this classification. In contrast to uncomplicated UTIs, management of most complicated infections depends on clinical experience and resources at individual institutions rather than on evidence based guidelines. Asymptomatic bacteriuria generally should not be treated except in high-risk catheterized patients and in pregnancy. UTIs in men generally require formal urologic evaluation. Our understanding of the etiologies, diagnostic strategies, and treatment options for prostatitis and the chronic pelvic pain syndrome in men continues to evolve.

The aim of this cross-sectional study was to compare single with repeated high-intensity focused ultrasound (HIFU) treatment in patients with localized prostate cancer, regarding treatment-related morbidity. A number of 223 consecutive patients with localized prostate cancer were treated with HIFU. Among them, 174 (78%) patients had one treatment, while 49 (22%) needed a second treatment. The patients' status and treatment-related side effects were followed up. The complications rates after one HIFU in 223 patients were: urinary tract infection 0.4%, chronic pelvic pain 0.9%, infravesical obstruction 19.7%, stressincontinence 7.6%, impotence 49.8%. Among the 49 patients who received a second HIFU therapy, the cumulative incontinence rate (12.2%; P = 0.024) and cumulative impotence rate (55%; P < 0.001) were significantly increased. Although there is an increase in morbidity if transrectal HIFU is repeated, the risk of side effects related to additional HIFU sessions in the case of primary treatment failure is still low.

The objective of this paper was to establish whether patients with confirmed painful bladder syndrome/interstitial cystitis (PBS/IC) presenting with symptoms of UTI have actual bacteriuria vs a flare of their PBS/IC symptoms. One hundred and six (n = 106) consecutive female patients (mean age 39.8 +/- 14 years) with newly diagnosed IC were identified and followed longitudinally for 24 months. At the initial visit and at all subsequent visits, urinary specimens were obtained by sterile catheterization (Bard 14Fr female) and cultured for bacteria. Eight patients had an initially positive urine culture, and repeat cultures 8 weeks after treatment were all negative. Once sterile urine was established, the diagnosis of PBS/IC was confirmed. A pelvic pain/urgency/frequency (PUF) questionnaire score was obtained from 89 patients. After the diagnosis of PBS/IC, all patients received multimodal treatment. Patients were instructed to present to the office whenever they developed symptoms of UTI, at which time a sterile catheter specimen was obtained and sent for culture. Greater than 10(3) colonies were considered positive. Patients who did not report flares were contacted to establish whether unreported treatments were given. Seventy-two patients (68%) had no UTI episodes or flares. The remaining 34 patients (32%) presented with 54 flares, of which 44 were culture-negative and 10 were culture-positive. A single flare was reported by 21 patients during the 24 months, with three positive cultures (14.3%). Recurrent UTI symptoms (two to four flares) were seen in a small group (n = 13) for a total of 33 flares. Of these, seven had two flares each (12 negative, 2 positive), five had three flares each (12 negative, 3 positive), and one patient had four flares (two negative, two positive). Therefore, within the group with recurrent symptoms, seven positive cultures were obtained for a rate of recurrent bacteriuria of 6.6% (7/106). Nine of the 10 positive bacterial cultures were due to gram-negative bacteria: Escherichia coli (n = 6), Proteus mirabilis (n = 1), Klebsiella pneumonia (n = 1), and Citrobacter sp. (n = 1). One grew Streptococcus sp. There was no difference between the flare group and nonflares in regards to age or PUF scores between groups. This study is the first to report on the low incidence of confirmed UTIs in a large group of PBS/IC patients followed longitudinally. These data suggest that only a small number of PBS/IC patients with UTI symptoms have positive urine cultures (9.4%; 10/106). Although the symptoms of recurrent UTI are prevalent in IC patients, the incidence of confirmed recurrent UTIs is only 6.6%. Because the flares of IC are usually self-limiting, treatment response to antibiotics may be misleading in light of the low incidence of positive urine cultures. These data suggest that the symptom flares of IC are not usually associated with recurrent UTI and, therefore, are likely due to a triggering of the other painful mechanisms involved in IC patients who are culture-negative.

Once thought to be rare, interstitial cystitis (IC) is now believed to have a markedly higher prevalence. This potentially devastating disease is also known as painful bladder syndrome (PBS) and can significantly impact quality of life. It is diagnosed by its symptoms, as there are no proven pathological findings. Unfortunately, the symptoms of IC/PBS overlap those of other common disease states such as overactive bladder, endometriosis, urinary tract infection, and prostatitis, which complicates the differential diagnosis. Understanding the presenting symptoms of urinary frequency, urinary urgency, and pelvic pain in the presence of otherwise normal findings can enhance primary care providers' ability to appropriately identify the disease. Early identification may allow initiation of therapy or referral before the disease becomes refractory to standard treatment, which typically includes behavioral therapy and possibly multimodal drug therapy.

Interstitial cystitis/painful bladder syndrome (IC/PBS) is characterized by urinary frequency, urgency, and pelvic pain in the absence of any other identifiable pathology. Initial identification of IC/PBS is challenging, as patients may have a range of symptoms that overlap with other disorders, including urinary tract infection (UTI). These patients may be treated empirically with antibiotics; however, many patients with such symptoms are actually culture negative and are later diagnosed with IC/PBS. This review describes the importance of recognizing the symptom overlap between IC/PBS and UTI and focuses on approaches to the diagnosis and management of IC/PBS. Physicians can improve patient care by considering IC/PBS early in the differential diagnosis.

CYSTOURETHROSCOPY: Cystourethroscopy is not recommended in the initial work-up of urinary incontinence except in the following circumstances: Microscopic or macroscopic haematuria requiring screening for an associated tumour especially in the presence of risk factors for urothelial tumour (smoking, occupational exposure). Signs of bladder irritation in the absence of urinary tract infection. Unexplained bladder or pelvic pain. Recurrent urinary tract infections. Discordance between clinical features and urodynamic assessment, which fails to reproduce the symptoms described by the patient. Work-up of a failure, recurrence or complication of urinary incontinence surgery. Suspected urogenital fistula. TEST FOR STERILE URINE: A test for sterile urine is recommended in the following situations: Woman with urge or mixed urinary incontinence. Elderly woman who regularly uses pads for urinary incontinence, regardless of the type of urinary incontinence. Before performing a urodynamic assessment or cystoscopy. This test can be performed by urine dipsticks or urine culture. URINE CYTOLOGY: Is not recommended in the assessment of pure urinary stress incontinence. But is recommended in the presence of signs of bladder irritation in the absence of urinary tract infection, microscopic haematuria, risk factors for bladder tumour (smoking, occupational exposure). And must be performed on concentrated urine by a urocytopathologist. PERINEAL ELECTROPHYSIOLOGICAL STUDIES: Perineal electrophysiological studies are not recommended in the investigation of non-neurological female urinary incontinence.

Elevated levels of prostate-specific antigen (PSA) in men may result from a variety of causes, such as prostate cancer, benign prostatic hyperplasia, acute urinary tract infection, and bacterial prostatitis. In recent years, several studies have also demonstrated a relationship between chronic prostatitis/chronic pelvic pain syndrome and increased PSA levels. However, asymptomatic patients are not routinely screened for this diagnosis before transrectal biopsy is performed to rule out prostate cancer. These asymptomatic men with elevated PSA levels frequently have evidence of inflammation when their expressed prostatic secretions are examined, or on their prostate biopsy specimens. This raises the problem of appropriate evaluation in the presence of chronic prostatitis and elevated PSA levels--not only in prostate cancer screening programmes, but also in cancer-negative biopsy findings. Evidence from the literature indicates that antimicrobial treatment may lower the PSA levels to what is considered the normal range. Despite that, general recommendations for the practical management are lacking and undetected prostate cancer in men with chronic prostatitis remains a difficult issue.

Despite the frequent association of urinary tract infection with vesicoureteral reflux and urinary calculi, since vesicouretal reflux is induced by bladder stones, the coexistence of vesicoureteral reflux and bladder stones is rare. Because of its occurrence in children belonging to poor socioeconomic groups, it is believed to be a deficiency disorder. Most cases of bladder stones occur between the ages of 2 and 5 years. Common clinical presentations of bladder stones include urinary dribbling and enuresis, frequency of micturition, pain during micturition, pelvic pain and hematuria. We report the occurrence of a large bladder stone in a boy, who experienced intermittent Lower abdominal pain and urinary incontinence, both during the day and at night. He had been diagnosed with enuresis and treated in pediatric clinics for 1 year. Delayed diagnosis resulted in bladder stone formation. The stone was larger than 2.5cm and open vesicolithotomy was therefore selected as the best and safest treatment choice. His symptoms disappeared after surgery. Thorough metabolic and environmental evaluations of such cases are required on an individual basis. Bladder stones should be considered as a possible diagnosis in children presenting with urinary incontinence.

The National Institutes of Health (NIH) has redefined prostatitis into four distinct entities. Category I is acute bacterial prostatitis. It is an acute prostatic infection with a uropathogen, often with systemic symptoms of fever, chills and hypotension. The treatment hinges on antimicrobials and drainage of the bladder because the inflamed prostate may block urinary flow. Category II prostatitis is called chronic bacterial prostatitis. It is characterized by recurrent episodes of documented urinary tract infections with the same uropathogen and causes pelvic pain, urinary symptoms and ejaculatory pain. It is diagnosed by means of localization cultures that are 90% accurate in localizing the source of recurrent infections within the lower urinary tract. Asymptomatic inflammatory prostatitis comprises NIH category IV. This entity is, by definition, asymptomatic and is often diagnosed incidentally during the evaluation of infertility or prostate cancer. The clinical significance of category IV prostatitis is unknown and it is often left untreated. Category III prostatitis is called chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). It is characterized by pelvic pain for more than 3 of the previous 6 months, urinary symptoms and painful ejaculation, without documented urinary tract infections from uropathogens. The syndrome can be devastating, affecting 10-15% of the male population, and results in nearly 2 million outpatient visits each year. The aetiology of CP/CPPS is poorly understood, but may be the result of an infectious or inflammatory initiator that results in neurological injury and eventually results in pelvic floor dysfunction in the form of increased pelvic muscle tone. The diagnosis relies on separating this entity from chronic bacterial prostatitis. If there is no history of documented urinary tract infections with a urinary tract pathogen, then cultures should be taken when patients are symptomatic. Prostatic localization cultures, called the Meares-Stamey 4 glass test, would identify the prostate as the source for a urinary tract infection in chronic bacterial prostatitis. If there is no infection, then the patient is likely to have CP/CPPS. For healthcare providers, the focus of therapy is symptomatic relief. The first therapeutic measure is often a 4- to 6-week course of a fluoroquinolone, which provides relief in 50% of men and is more efficacious if prescribed soon after symptoms begin. Second-line pharmacotherapy involves anti-inflammatory agents for pain symptoms and alpha-adrenergic receptor antagonists (alpha-blockers) for urinary symptoms. Potentially more effective is pelvic floor training/biofeedback, but randomized controlled trials are needed to confirm this. Third-line agents include 5alpha-reductase inhibitors, glycosaminoglycans, quercetin, cernilton (CN-009) and saw palmetto. For treatment refractory patients, surgical interventions can be offered. Transurethral microwave therapy to ablate prostatic tissue has shown some promise. The treatment algorithm provided in this review involves a 4- to 6-week course of antibacterials, which may be repeated if the initial course provides relief. Pain and urinary symptoms can be ameliorated with anti-inflammatories and alpha-blockers. If the relief is not significant, then patients should be referred for biofeedback. Minimally invasive surgical options should be reserved for treatment-refractory patients.

Introduction. We presented two cases of late presentation of ovarian vein thrombosis postpartum following vaginal delivery and cesarean section within a short period in our institution. Both of them had pelvic pain following their deliveries which was associated with fever and chills. One of them was quite a big-sized thrombophlebitic vein which was about 10 x 6 x 5 centimeters following a computed tomography. They were both treated initially for urinary tract infection, while a large ovarian vein thrombosis was not diagnosed in the second patient until her emergency department admission. Conclusion. Ovarian vein thrombosis is rare, but could present late, and difficult to diagnose, hence, should be considered as a differential diagnosis in a postpartum woman with fever and tender pelvic mass.
