Should We Delay Urodynamic Study When Patients With Spinal Cord Injury Have Asymptomatic Pyuria?

ABSTRACT:

Objective

To assess the incidence of urinary tract infection (UTI) with post-urodynamic study (post-UDS) in patients with spinal cord injury (SCI) and study its relationship with pre-UDS pyuria.

Methods

Patients with SCI who were hospitalized and underwent UDS during a 4-year period were reviewed. Patients with pre-test lower urinary tract symptoms were excluded. Urinalysis and urine culture were performed before and 24 hours after UDS. Prophylactic antibiotics were administered for 5 days starting from the morning of the UDS. UTI was defined as bacteriuria with accompanying symptoms.

Results

Of 399 patients reviewed, 209 (52.4%) had pyuria in pre-UDS urinalysis, and 257 (64.4%) had bacteriuria in pre-UDS culture. Post-UDS UTI occurred in 6 (1.5%) individuals who all complained of fever: 5 (2.4%) of the post-UDS UTI cases occurred in patients with pre-UDS pyuria, and 1 (0.5%) in a person without. The differences between groups were not statistically significant (p=0.218). Of 221 patients with bacteriuria (gram-negative isolates) on pre-UDS culture, resistance to ciprofloxacin, cephalosporin, and trimethoprim/sulfamethoxazole (TMP/SMT) was noted in 52.9% (117 cases), 57.0% (126 cases), and 38.9% (86 cases), respectively.

Conclusion

No difference was found in the prevalence of post-UDS UTI based on the presence of pyuria in pre-UDS urinalysis. UDS may be performed even in SCI cases of pre-UDS pyuria without increasing the prevalence of post-UDS UTI if prophylactic antibiotics are administered. TMP/SMT could be used as a first-line antibiotic for the prevention of post-UDS UTI in Korea.

Project description:Human intestinal flora comprises thousands of bacterial species. Growth and composition of intestinal microbiota is dependent on various parameters, including immune mechanisms, dietary factors and intestinal motility. Patients with spinal cord injury (SCI) frequently display neurogenic bowel dysfunction due to the absence of central nervous system control over the gastrointestinal system. Considering the bowel dysfunction and altered colonic transit time in patients with SCI, we hypothesized the presence of a significant change in the composition of their gut microbiome. The objective of this study was to characterize the gut microbiota in adult SCI patients with different types of bowel dysfunction. We tested our hypothesis on 30 SCI patients (15 upper motor neuron [UMN] bowel syndrome, 15 lower motor neuron [LMN] bowel syndrome) and 10 healthy controls using the 16S rRNA sequencing. Gut microbial patterns were sampled from feces. Independent of study groups, gut microbiota of the participants were dominated by Blautia, Bifidobacterium, Faecalibacterium and Ruminococcus. When we compared all study groups, Roseburia, Pseudobutyrivibrio, Dialister, Marvinbryantia and Megamonas appeared as the genera that were statistically different between groups. In comparison to the healthy group, total bacterial counts of Pseudobutyrivibrio, Dialister and Megamonas genera were significantly lower in UMN bowel dysfunction group. The total bacterial count of Marvinbryantia genus was significantly lower in UMN bowel dysfunction group when compared to the LMN group. Total bacterial counts of Roseburia, Pseudobutyrivibrio and Megamonas genera were significantly lower in LMN bowel dysfunction group when compared to healthy groups. Our results demonstrate for the first time that butyrate-producing members are specifically reduced in SCI patients when compared to healthy subjects. The results of this study would be of interest since to our knowledge, microbiome-associated studies targeting SCI patients are non-existent and the results might help explain possible implications of gut microbiome in SCI.
