More than 75% of hospital-acquired or nosocomial urinary tract infections are initiated by urinary catheters, which are used during the treatment of 15–25% of hospitalized patients. Among other purposes, urinary catheters are primarily used for draining urine after surgeries and for urinary incontinence. During catheter-associated urinary tract infections, bacteria travel up to the bladder and cause infection. A major cause of catheter-associated urinary tract infection is attributed to the use of non-ideal materials in the fabrication of urinary catheters. Such materials allow for the colonization of microorganisms, leading to bacteriuria and infection, depending on the severity of symptoms. The ideal urinary catheter is made out of materials that are biocompatible, antimicrobial, and antifouling. Although an abundance of research has been conducted over the last forty-five years on the subject, the ideal biomaterial, especially for long-term catheterization of more than a month, has yet to be developed. The aim of this review is to highlight the recent advances (over the past 10 years) in developing antimicrobial materials for urinary catheters and to outline future requirements and prospects that guide catheter materials selection and design.

“…Silver-substituted hydroxyapatites (Ag-HAps) have been synthesized using different amounts of silver in the range 0.1-10.0 wt%, following several methods: (i) precipitation route [161,181,182], starting either from salt precursors [183][184][185][186][187][188][189][190][191] or acids as well as bases and oxides [192]; (ii) sol-gel process [141,162,[193][194][195][196]; (iii) ion exchange between pure hydroxyapatite and a silver salt solution [161,185,[197][198][199]; (iv) ultrasonic spray pyrolysis (USSP) [200]; (v) microwave method [161,201]; (vi) combustion synthesis [202]; and (vii) co-sputtering process [203]. The synthesized materials can be submitted to either drying in an oven or freezedrying, obtaining powders with different crystallinity degrees and specific surface areas and, consequently, different efficiencies of the antibacterial activity.…”

“…It usually takes shorter time for wound healing in acidic environment than alkaline environment. The release of anti-bacterial silver ions can highly vary depending on the moisture content or the pH of the surrounding environment in contact with the films [46,47]. In order to evaluate the silver ion release of BC-Ag nanocomposites, the release behaviors were monitored on a daily basis in 10 mM HEPES buffer at different pH.…”
