ABSTRACT A recent Best Practice Statement published by the American Urological Association (AUA) recommends that antibiotic therapy in patients undergoing midurethral synthetic slings (MUS) should be 24 hours or less. Subjects at our institution are routinely administered a single dose of intravenous antibiotics before MUS surgery. We prospectively evaluated urinary tract infection (UTI) rates and risk factors for UTI in subjects undergoing MUS who receive single-dose antibiotic therapy.
Adult female patients who were undergoing MUS for stress or mixed urinary incontinence were prospectively included and received a single-dose of an intravenous antibiotic in accordance with the AUA Best Practice Statement. Subjects requiring additional procedures for prolapse were excluded. Baseline characteristics and preoperative and postoperative postvoid residual (PVR) were documented. Subjects were contacted within 1 week of surgery, and seen in the office at 1 month, when a urinalysis was performed, and urine culture sent if subjects were symptomatic.
A total of 101 subjects underwent solitary MUS and received a single dose of intravenous antibiotics. Overall, 6 (5.9%) subjects developed a UTI within 1 month of surgery. Patients who developed a UTI were more likely to have elevated PVRs at the preoperative office visit (62.2 vs 26.8 mL, P = .004).
Our study has demonstrated that the rate of perioperative UTI after MUS with one perioperative dose of intravenous antibiotics is low. Patients with an elevated preoperative PVR may be at an increased risk of developing a UTI. Single-dose antibiotic administration is safe and effective at preventing perioperative UTI in subjects undergoing solitary MUS.

    ABSTRACT: To evaluate whether nitrofurantoin prophylaxis prevents postoperative urinary tract infection (UTI) in patients receiving transurethral catheterization after pelvic reconstructive surgery. In a randomized, double-blind, placebo-controlled trial, participants undergoing pelvic reconstructive surgery were randomized to 100 mg nitrofurantoin or placebo once daily during catheterization if they were: 1) discharged with a transurethral Foley or performing intermittent self-catheterization; or 2) hospitalized overnight with a transurethral Foley. Our primary outcome was treatment for clinically suspected or culture-proven UTI within 3 weeks of surgery. Statistical analysis was performed by χ and logistic regression. Assuming 80% power at a P value of .05, 156 participants were needed to demonstrate a two-thirds reduction in UTI. Of 159 participants, 81 (51%) received nitrofurantoin and 78 (49%) received placebo. There were no significant differences in baseline demographics, intraoperative characteristics, duration and type of catheterization, or postoperative hospitalization, except a lower rate of hysterectomy in the nitrofurantoin group. Nitrofurantoin prophylaxis did not reduce the risk of UTI treatment within 3 weeks of surgery (22% UTI with nitrofurantoin compared with 13% UTI with placebo, relative risk 1.73, 95% confidence interval 0.85-3.52, P=.12). Urinary tract infection treatment was higher in premenopausal women, lower in diabetics, and increased with longer duration of catheterization. In logistic regression adjusting for menopause, diabetes, preoperative postvoid residual volume, creatinine clearance, hysterectomy, and duration of catheterization, there was still no difference in UTI with nitrofurantoin as compared with placebo. Prophylaxis with daily nitrofurantoin during catheterization does not reduce the risk of postoperative UTI in patients receiving short-term transurethral catheterization after pelvic reconstructive surgery.,, NCT01450800. : I.

    ABSTRACT: While surgical options for stress urinary incontinence and pelvic organ prolapse continue to become less-invasive, complications can still occur. Measures to standardize the preoperative diagnosis and treatment options are currently being developed. Likewise, the American Urological Association has developed best practice statements regarding the administration of perioperative antibiotics and prevention of deep vein thrombosis in patients undergoing pelvic surgery. Furthermore, other perioperative steps, such as the type of bowel preparation and proper patient positioning, play a significant role in perioperative morbidity. A discussion of available evidence regarding these perioperative issues is presented in this paper.

    ABSTRACT: To describe the use of antibiotics for urinary tract infection (UTI) before and after surgery for urinary incontinence (UI); and for those with use of antibiotics before surgery, to estimate the risk of treatment for a postoperative UTI, relative to those without use of antibiotics before surgery. A historical population-based cohort study. Denmark. Women (age ≥18 years) with a primary surgical procedure for UI from the county of Funen and the Region of Southern Denmark from 1996 throughout 2010. Data on redeemed prescriptions of antibiotics ±365 days from the date of surgery were extracted from a prescription database. Use of antibiotics for UTI in relation to UI surgery, and the risk of being a postoperative user of antibiotics for UTI among preoperative users. A total of 2151 women had a primary surgical procedure for UI; of these 496 (23.1%) were preoperative users of antibiotics for UTI. Among preoperative users, 129 (26%) and 215 (43.3%) also redeemed prescriptions of antibiotics for UTI within 0-60 and 61-365 days after surgery, respectively. Among preoperative non-users, 182 (11.0%) and 235 (14.2%) redeemed prescriptions within 0-60 and 61-365 days after surgery, respectively. Presurgery exposure to antibiotics for UTI was a strong risk factor for postoperative treatment for UTI, both within 0-60 days (adjusted OR, aOR=2.6 (95% CI 2.0 to 3.5)) and within 61-365 days (aOR=4.5 (95% CI 3.5 to 5.7)). 1 in 4 women undergoing surgery for UI was treated for UTI before surgery, and half of them had a continuing tendency to UTIs after surgery. Use of antibiotics for UTI before surgery was a strong risk factor for antibiotic use after surgery. In women not using antibiotics for UTI before surgery only a minor proportion initiated use after surgery.
