Is it time to abandon the use of amphotericin B bladder irrigation?

In this article, we review the issues surrounding funguria and its management. With this background, the value of bladder irrigation with amphotericin B for the management of funguria is directly examined. Amphotericin B bladder irrigation is used frequently in clinical practice. Although its use is not standardized, there are multiple studies that attempt to show the impact on funguria management. These bladder irrigations have been used either for treatment of funguria or (less commonly) as a diagnostic test in attempts to identify upper urinary tract disease. Despite their widespread therapeutic use and relative safety, it is not clear from our experience and a review of the literature that amphotericin B bladder irrigations have any diagnostic or therapeutic value. The patient may be best served by removal of the urinary catheter, if possible, rather than by instillation of bladder irrigation with amphotericin B.
