RESUMO
INTRODUCTION AND HYPOTHESIS: Urinary tract infections (UTIs) are one of the most common complications of urogynecological surgeries. The risk of UTIs is increased by the catheterization of the bladder, intraoperative cystoscopy, and urine retention after the procedure. Due to increasing antibiotic resistance, there is a need to search for new methods of postoperative UTI prevention. Canephron is a mixture of century herbs, lovage roots, and rosemary leaves with diuretic, spasmolytic, anti-inflammatory, antibacterial, and nephroprotective properties. The aim of this study is to demonstrate the noninferiority of Canephron versus antibiotic prophylaxis with fosfomycin trometamol (FT), based on the collective results of postoperative urine culture analyses. METHODS: One hundred and twenty-five female patients were randomized into two groups before undergoing urogynecological surgeries, including a control group (n = 67), which received one dose of 3 g of FT the day after the procedure, and a study group (n = 58), which received Canephron three times a day for 14 days, starting the day after the procedure. All the patients were assessed using the Acute Cystitis Symptom Score (ACSS). RESULTS: UTIs were observed in 6.4% of the patients. There was no statistically significant difference between the use of FT and Canephron in terms of UTIs (Chi^2 N-1 = 0.8837; p = ns). Additional factors, such as menopausal status and the type of procedure performed, increased the risk of developing a UTI. Factors such as the body mass index (BMI) and parity had no correlation. CONCLUSIONS: Canephron is noninferior to FT in the prevention of postoperative UTIs. The use of such a phytotherapeutic drug may help to decrease antibiotic consumption, which is closely connected to the growing trend of antibiotic resistance.
RESUMO
AIM: The aim of this observational study was to evaluate the effectiveness of a phytotherapic drug (Canephron N) in preventing urinary tract infection (UTI) in high-risk women undergoing urodynamic studies (UDS). METHODS: The study protocol was approved by the local institutional ethical committee. Adult women with at least one risk factor for acquiring UTI (defined as: age over 70, elevated postvoid residual urine>100 ml, recurrent UTI, pelvic organ prolapse (POP) ≥II in POP-Q scale, and neurogenic bladder) had received after UDS either a single oral dose of fosfomycin trometamol (FT) (3 grams) or a phytodrug containing centaury herb, lovage root, and rosemary leaves (5 ml taken orally three times daily for one week). All patients included in the study had no pyuria according to urine dipstick (nitrite and/or blood and/or leukocyte esterase) and negative urine culture (CFU < 103/ml) before UDS. Urine samples were also tested 7 days after UDS. RESULTS: Seventy-two high-risk participants completed the study. Seven days after urodynamic studies UTI symptoms, pyuria (nitrite and/or blood and/or leukocyte esterase) and bacteriuria with E. coli occurred in two patients (one (2.8%) in the FT and one (2.7%) in the phytodrug group, respectively). No statistical differences in UTI incidence were found between both treatment groups. We did not observe any additional adverse events in both groups. The major disadvantage of prophylaxis with the phytodrug as compared to FT was the necessity of continuing therapy for 7 days. CONCLUSION: Prophylaxis of UTI with a phytodrug (Canephron N) may be considered a good alternative to antibiotic prophylaxis use after UDS in high-risk female patients.
