SARS-CoV-2 infection is linked in men with increased incidence of urinary retention, urinary tract infection (UTI), and blood in the urine, a new study finds.
Authors of the study, led by Alex Qinyang Liu, of S.H. Ho Urology Centre, at The Chinese University of Hong Kong, highlighted the clinical implications.
“Clinicians should be aware of the significantly higher incidence of LUTS [lower urinary tract symptoms] complications with COVID-19 in this patient group and understand that these urological manifestations can occur regardless of COVID-19 severity,” the authors wrote.
Findings were published online in the Journal of Internal Medicine.
They explained that current literature has included only small case series and observational studies assessing the connection between COVID-19 and male LUTS.
Nearly 18,000 patients in study
Included in this study were all male patients who used the public health care system in Hong Kong who received alpha-blocker monotherapy for LUTS from 2021 to 2022. After propensity score matching, 17,986 patients were included. Half had polymerase chain reaction–confirmed SARS-CoV-2 infection (n = 8,993).
The retrospective study compared urologic outcomes, including male benign prostatic hyperplasia (BPH) complications, and changes in medical treatment in the two groups. They compared male patients with SARS-CoV-2 infection who were taking baseline alpha blocker monotherapy for LUTS with a control group who had no SARS-CoV-2 infection.
They found that, compared with controls, the SARS-CoV-2–infected group had significantly higher incidence of retention of urine (4.55% vs. 0.86%, P < .001), hematuria (1.36% vs. 0.41%, P < .001), clinical UTI (4.31% vs. 1.49%, P < .001), culture-proven bacteriuria (9.02% vs. 1.97%, P < .001), and addition of 5-alpha reductase inhibitors (0.50% vs. 0.02%, P < .001).
Similar side effects even with asymptomatic infection
The researchers pointed out that similar incidence of retention of urine, hematuria, and addition of medication were seen even when patients had asymptomatic infection.
They added that their findings have biological plausibility because the coexpression of the proteins ACE2 and TMPRSS2 in the prostate makes it a target for SARS-CoV-2, which leads to inflammation and may help explain the primary outcomes.
“Given the high infectivity and unprecedented scale of the COVID-19 pandemic, these urological symptoms and complications represent a significant clinical burden that clinicians and urologists should be aware of,” the authors wrote.
The authors noted that the prevalence of BPH and LUTS rises with age and are among the most common urologic conditions affecting older men. “Incidentally, male patients of advanced age are also more significantly affected by COVID-19.”
The authors declare no relevant financial relationships.
