The Role of the Genitourinary Microbiome in Pediatric Urology: a Review
Abstract
Purpose of review: In this review, we highlight the effects of the microbiome on urologic diseases that affect the pediatric patient.
Recent findings: Perturbations in the urinary microbiome have been shown to be associated with a number of urologic diseases affecting children, namely urinary tract infection, overactive bladder/urge urinary incontinence, and urolithiasis. Recently, improved cultivation and sequencing technologies have allowed for the discovery of a significant and diverse microbiome in the bladder, previously assumed to be sterile. Early studies aimed to identify the resident bacterial species and demonstrate the efficacy of sequencing and enhanced quantitative urine culture. More recently, research has sought to elucidate the association between the microbiome and urologic disease, as well as to demonstrate effects of manipulation of the microbiome on various urologic pathologies. With an improved appreciation for the impact of the urinary microbiome on urologic disease, researchers have begun to explore the impact of these resident bacteria in pediatric urology.
Keywords: Genitourinary microbiome; Pediatric urology; Urinary incontinence; Urolithiasis; Urologic diseases.

(2014) was of importance because it not only demonstrated differences in the urinary microbiome between patients with and without UUI but it also showed that there was variation in species of Lactobacillus in these patients. Importantly, Lactobacillus species that produce more lacticacid are more common in patients without UUI, while those that produce less lactic acid are more common in UUI sufferers. This suggests acification of the bladder microbiome could be protective, mirroring a similar hypothesis in the vaginal microbiome. - PMC - PubMed
