Официальное название

Methenamine Hippurate Compared to Typical Antibiotic Prophylaxis in the Prevention of Urinary Tract Infection Following Intradetrusor OnabotulinumtoxinA Injection for Treatment of Overactive Bladder: a Randomized Controlled Non-Inferiority Trial

Обзор

The goal of this clinical trial is to compare methenamine hippurate prophylaxis to routine antibiotic prophylaxis following onabotulinumtoxinA (BOTOX-A) injections in women with overactive bladder (OAB). Participants will be randomly selected to receive one of the two post-procedural prophylaxis medications. The primary outcome measure will be urinary tract infection (UTI) rates within 30 days from the BOTOX-A procedure. Secondary outcomes will assess patient satisfaction with the two post-procedural prophylaxis medications.

Подробное описание

The purpose of this randomized controlled non-inferiority study is to determine if methenamine hippurate is non-inferior in regards to UTI rate when compared to routinely prescribed antibiotic prophylaxis following intradetrusor BOTOX-A injections for women with OAB. As a secondary aim, this study will also compare patient medication satisfaction, as measured by the Functional Assessment of Chronic Illness Therapy-Treatment Satisfaction-General (FACIT-TS-G) for the two prophylactic medication arms.

Comparators: Methenamine hippurate versus routinely prescribed antibiotic prophylaxis Methenamine hippurate is an oral non-antibiotic antiseptic medication widely used in the prevention of recurrent UTIs.

164 women will be randomly assigned to each treatment option: 82 to methenamine hippurate and 82 to routinely prescribed antibiotic prophylaxis. The primary outcome of UTI rates within 30 days of the BOTOX-A procedure will be calculated for each study arm. The FACIT-TS-G will be administered to participants at the conclusion of the 30-day period.

Вмешательства

  • Препарат Methenamine Hippurate
    Drug: Methenamine hippurate 1 gram by mouth twice daily for three days.
  • Препарат Typically prescribed oral antibiotic prophylaxis
    Drug: typically prescribed oral antibiotic prophylaxis following intradetrusor BOTOX-A injections. This includes, but is not limited to, antibiotic medications such as nitrofurantoin, amoxicillin/clavulanic acid, and trimethoprim/sulfamethoxazole. Dosage will be determined per usual care. Duration of treatment will be standardized to three days.
