Prospective follow-up of overactive bladder symptoms in patients with prior SARS-CoV-2 infection.

Abstract

SARS-CoV-2 infection can result in genitourinary symptoms, such as frequency, urgency, nocturia, and pain/pressure. In this study, we followed the progression of overactive bladder (OAB) symptoms in patients that reported new or worsening OAB symptoms after coronavirus disease-19 (COVID-19) diagnosis. Individuals from a COVID-19 serology study were invited to participate in a follow-up study. Respondents were divided into three groups based on prior COVID-19 testing. Patients scored symptoms retrospectively before the pandemic, at study onset, and prospectively during 12-month follow-up. Genitourinary symptoms were assessed using international consultation on incontinence questionaire for OAB (ICIQ-OAB). Change in ICIQ-OAB scores from baseline were calculated. The minimal important difference of one on ICIQ-OAB is considered a significant change. 26.0% of participants previously had positive COVID polymerase chain reaction (PCR) test (PCR+), 5.6% a positive serology test only (Ser+), and 65.5% were COVID naïve (COVID-). 23.8% of participants reported a significant increase in ICIQ-OAB score at study onset compared to prepandemic. ICIQ-OAB scores were similar at prepandemic but significantly higher at study start (p < 0.001) in PCR+ group. During follow-up, change in ICIQ-OAB scores from baseline remained unchanged for COVID- group, but gradually reduced for PCR+, reaching similar levels as COVID- group by 12 months. By 12 months, 71.4% of PCR+, 42.9% of Ser+, and 68.8% of COVID- participants still reported significant increase in ICIQ-OAB scores. Most COVID-19 patients experienced return of symptoms to baseline, indicative of the potential resolution of COVID-associated cystitis. A subset of cases did not, raising questions about the underlying factors contributing to this outcome. Additional research is needed to assess long COVID on urological health.
