* '''<span style="color:#ff0000">Acute cystitis episodes in patients with recurrent UTI'''
** '''<span style="color:#ff0000">Obtain urinalysis, urine culture and sensitivity with each symptomatic acute cystitis episode prior to initiating treatment in patients with rUTIs'''
*** Continued documentation of cultures during symptomatic periods prior to starting antibiotics helps to provide a baseline against which interventions can be evaluated, to determine the appropriate pathway within the treatment algorithm, and to allow for the tailoring of therapy based on bacterial sensitivities.
*** '''In select patients with rUTIs with symptoms of recurrence, presumptive treatment with antibiotics can be initiated prior to finalization of the culture''' based on prior speciation, susceptibilities, and local antibiogram
** '''Use first-line therapy (See [https://www.auanet.org/guidelines-and-quality/guidelines/recurrent-uti Table 3] (statement 9, no direct link) from Original Guideline) dependent on the local antibiogram for treatment of symptomatic UTIs in women'''
*** <span style="color:#ff0000">'''Options (3):'''</span>
****<span style="color:#ff0000">'''Fosfomycin 3g PO x 1'''</span>
****<span style="color:#ff0000">'''TMP-SMX one tab DS PO BID x 3 days'''</span>
****<span style="color:#ff0000">'''Nitrofurantoin 100mg PO BID x 5 days'''</span>
***A systematic review found no differences between fluoroquinolones, β-lactams (e.g., penicillins and its derivatives, cephalosporins), nitrofurantoin or TMP-SMX in the efficacy or risk of discontinuation due to adverse events
*** TMP-SMX is not recommended for empiric use in areas where local resistance rates > 20%]
***'''Table 3 from guideline suggests that nitrofurantoin does not cover enterococcus but CW11 Table 12-5/CW12 Table 55-6 suggests that it does'''
** '''Clinicians should treat rUTI patients experiencing acute cystitis episodes with as short a duration of antibiotics as reasonable, generally < 7 days'''
*** '''In patients with rUTIs experiencing acute cystitis episodes associated with urine cultures resistant to oral antibiotics''', clinicians may treat with culture-directed parenteral antibiotics for as short a course as reasonable, generally no longer than 7 days. '''Many such infections will be caused by organisms producing ESBLs.'''
**** '''Generally, such organisms are susceptible only to carbapenems. However, clinicians should order fosfomycin susceptibility testing, as many MDR uropathogens, including ESBL-producing bacteria, retain susceptibility to Fosfomycin thereby providing an oral option'''.
** '''Do not perform a post-treatment test of cure (urinalysis or urine culture) in asymptomatic patients'''
*** Extrapolating from the asymptomatic bacteruria literature, repeat urine culture after successful UTI treatment may lead to overtreatment
*** '''Omit surveillance urine testing, including urine culture, in asymptomatic patients with rUTIs.'''
**** While pregnant women and patients undergoing invasive urologic procedures do benefit from treatment, substantial evidence supports that other populations, including women with diabetes mellitus and long-term care facility residents, do not require or benefit from additional evaluation or antibiotic treatment
** '''Repeat urine cultures to guide further management when UTI symptoms persist following antibiotic therapy'''
*** '''After initiating antibiotic therapy for UTI, clinical cure (i.e. UTI symptom resolution) is expected within 3-7 days.''' Although there is no evidence, it is reasonable to '''repeat a urine culture if symptoms persist > 7 days'''
* '''<span style="color:#ff0000">Antibiotics to reduce UTI episodes in patients with rUTI (self-start vs. prophylaxis)</span>'''
*# '''<span style="color:#ff0000">Self-start antibiotics: patient-initiated treatment for acute episodes while awaiting urine cultures.'''</span>
*#* '''For reliable patients, consider shared decision-making with regards to deferring therapy prior to obtaining results from the urine culture.'''
*#* Despite the original concept behind self-start therapy that allowed for women to treat their UTI without obtaining a culture. given more recent goals to reduce overuse of antibiotics and the development of antibacterial resistance, '''obtaining culture data for symptomatic recurrences is recommended''', when feasible.
*# '''<span style="color:#ff0000">Antibiotic prophylaxis (continuous vs. post-coital)</span>'''
*## '''Continuous:''' After discussion of the risks and benefits, clinicians may prescribe continuous antibiotic prophylaxis to decrease the risk of future UTIs in women of all ages previously diagnosed with UTIs.
*##* '''Antibiotic prophylaxis reduces the number of clinical recurrences but increases risk of adverse events. Once the antibiotics are stopped, UTIs recur at the baseline rate.'''
*##* '''The dosing options for continuous prophylaxis include the following:'''
*##** Nitrofurantoin monohydrate/macrocrystals 50mg daily
*##** '''Nitrofurantoin''' monohydrate/macrocrystals '''100mg daily'''
*##** Cephalexin 125mg once daily
*##** '''Cephalexin 250mg once daily'''
*##** TMP 100mg once daily
*##** '''TMP-SMX''' '''40mg/200mg once daily'''
*##** TMP-SMX 40mg/200mg thrice weekly
*##** '''Fosfomycin 3g every 10 days'''
*##* '''Potential adverse effects of gastrointestinal disturbances and skin rash are commonly associated with antibiotics, including TMP, TMP-SMX, cephalexin, and Fosfomycin'''
*##* '''<span style="color:#ff0000">Potentially serious risks with nitrofurantoin include pulmonary and hepatic toxicity.</span>'''
*##** The rate of possible serious pulmonary or hepatic adverse events has been reported to be 0.001% and 0.0003%, respectively.
*##* '''<span style="color:#ff0000">The use of fluoroquinolones (e.g. ciprofloxacin) for prophylactic antibiotic use is not recommended in current clinical practice.</span>'''
*##** '''<span style="color:#ff0000">Fluoroquinolone agents have potentially adverse side effects including QTc prolongation, tendon rupture, and increased risk of aortic rupture</span>'''
*##* '''The duration of prophylaxis can vary from 3-12 months''', with periodic assessment
*## '''Post-coital'''
*##* '''In women with UTIs temporally related to sexual activity, a single dose of antibiotic prophylaxis taken before or after sexual intercourse is effective and safe'''
*##** Options:
*##*** TMP-SMX 40mg/200mg
*##*** TMP-SMX 80mg/400mg
*##*** Nitrofurantoin 50-100mg
*##*** Cephalexin 250mg
