The efficacy of fosfomycin trometamol in prevention of postoperative urinary tract infection in pregnant women after endoscopic procedures: open clinical trial

Abstract

Background Fosfomycin tromethamine is recommended (category B) for the treatment of urinary tract infections in pregnant women. We aimed to evaluate the efficacy of single-dose preoperative fosfomycin tromethamine in the prevention of urinary tract infection in pregnant women who underwent lower urinary tract endoscopic surgeries. Methodology The subjects of this study were pregnant women who underwent lower urinary tract endoscopic procedures. All patients received Fosfomycin tromethamine1 packet (3 g) dissolved in water the day before surgery. Routine pre- and postoperative urine analysis and urine cultures were performed when needed. Patients were monitored for urinary tract infections and the side effects of the drug. Moreover, maternal and fetal complications were monitored. Results The study was conducted on 31 pregnant women with a mean age of 24.48 ± 5.35 years. The endoscopic procedures were as follows: 28 (90.3%) DJ ureteric insertions for hydronephrosis, 2 (6.5%) urinary bladder stones, and cystoscopy (3.2%) for gross hematuria. Two (6.5%) patients had postoperative asymptomatic bacteriuria that resolved with oral antibiotic therapy. Conclusion Fosfomycin tromethamine is safe in preventing urinary tract infection and decreases the need for postoperative parenteral antibiotics in pregnant women who require lower urinary tract endoscopic procedures.

“…A ITU e suas complicações relacionadas causam cerca de 150 milhões de mortes por ano em todo o mundo. Vale ressaltar que a bacteriúria assintomática (ASB) é de particular importância devido à ausência de qualquer sintoma (Radwan et al, 2021).…”
