Recurrent Urinary Tract Infections (UTIs): A Review and Proposal for Clinicians

Open access

Abstract

The pathogenesis of recurrent urinary tract infections (rUTIs), a common problem in the female population, is becoming better understood following recent studies of bacterial persistence and intracellular bacterial communities. Incorporating these new insights, we propose pulsed antibiotic therapy with intracellular activity as a possible treatment for rUTIs.

Figure 2 Diagram of the urinary bladder with intracellular bacterial community (IBC) maturation and development. The left half of the bladder (urine culture: positive) shows phases of IBC development during which bacteria are present in the lumen of the bladder with bacteria susceptible to antibiotics and detected by the host immune system. The right half of the bladder (urine culture: negative) shows phases of IBC development with bacteria protected from antibiotic therapy and undetected by the host immune system (modified from Kim A and others, 2021) [13].

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
