Do we have enough evidence to propose a urinary biomarker of bladder ischemia? A systematic review and meta-analysis
Objective
Urinary bladder ischemia has been implicated in the pathogenesis of lower urinary tract symptoms (LUTS). However, research regarding urinary molecular markers for diagnosis and prognosis of pelvic ischemia is still premature, hindering further implementation in clinical practice. The aim of this study is to systematically appraise biomarkers associated with bladder ischemia detected in urine.
Methods
We performed a systematic review of PubMed/Medline, Embase, Web of Science, and the Cochrane Library in October 2021 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. A subsequent reference search of retrieved articles was also performed. The identified reports were reviewed according to Systematic Review Center for Laboratory Animal Experimentation's risk-of-bias tool for animal studies.
Results
Eight publications were selected for this analysis. The included reports used 8-hydroxy-2′-deoxyguanosine (8-OHdG) (in eight studies) as urinary marker of bladder ischemia. The pooled mean difference for urinary 8-OHdG levels between study and control groups was 13.73 ng/mg creatinine (95% CI, 9.79-17.67; P < .001; I2 = 69%) for rat studies and 3.71 ng/mg creatinine (95% CI, 2.91-4.51; P < .001; I2 = 94%) for rabbit studies. The result remained statistically significant favoring the control group independent of the type of intervention used to achieve bladder ischemia. Regarding secondary outcomes, mean voided volume and micturition interval were significantly lower in the ischemia group.
Conclusion
The lack of human randomized controlled trials is a major limitation. 8-OHdG is a urinary biomarker to be investigated in future studies for diagnosis and prognosis of LUTS in patients with vascular injury or bladder outlet obstruction.
期刊介绍：
LUTS is designed for the timely communication of peer-reviewed studies which provides new clinical and basic science information to physicians and researchers in the field of neurourology, urodynamics and urogynecology. Contributions are reviewed and selected by a group of distinguished referees from around the world, some of whom constitute the journal''s Editorial Board. The journal covers both basic and clinical research on lower urinary tract dysfunctions (LUTD), such as overactive bladder (OAB), detrusor underactivity, benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), urinary incontinence, pelvic organ prolapse (POP), painful bladder syndrome (PBS), as well as on other relevant conditions. Case reports are published only if new findings are provided.
LUTS is an official journal of the Japanese Continence Society, the Korean Continence Society, and the Taiwanese Continence Society. Submission of papers from all countries are welcome. LUTS has been accepted into Science Citation Index Expanded (SCIE) with a 2011 Impact Factor.
