Impact of Covid-19 Infection on Incidence and Exacerbation of Overactive Bladder Symptoms: A Systematic Review
Bibliographic record
Abstract
Background The COVID-19 pandemic continues to be a major global health concern. A key factor is the presence of angiotensin-converting enzyme 2 (ACE2) receptors in various organs, including the lungs, heart, bladder, and testicles. These receptors allow the SARS-CoV-2 virus to enter cells, making these organs vulnerable to damage. This vulnerability may explain why some patients experience non-respiratory symptoms. Notably, overactive bladder (OAB) symptoms and a condition called COVID-associated cystitis (CAC) have been reported to negatively affect the quality of life of COVID-19 patients. A systematic review is needed to summarize the current understanding of these urological aspects of SARS-CoV-2 infection, considering both short- and long-term effects. Methods We conducted a systematic review in accordance with PRISMA guidelines to investigate urological complications of COVID-19, with a specific focus on OAB symptoms and CAC (characterized by frequent urination, urgency, and nocturia). We searched databases, including Medline (PubMed), Embase, and Scopus. Two reviewers independently screened the studies, and the quality of each study was assessed using the Newcastle-Ottawa Scale (NOS). Results Our search identified 343 articles published up to March 2024, of which 12 were included in this review. Many of the studies utilized scoring systems such as the International Prostate Symptom Score (IPSS) and OAB symptom scores. The evidence suggests that COVID-19 may trigger or worsen lower urinary tract symptoms, OAB, and cystitis in some patients, regardless of gender or age. However, these effects appear to be uncommon. Several studies reported an increase in IPSS scores, though it remains unclear whether this increase is temporary or long-lasting. A few studies found that symptoms resolved over several months. Conclusion This systematic review suggests that COVID-19 may affect the urinary system, leading to symptoms such as frequent urination, urgency, and nocturia. These symptoms can negatively impact the quality of life in COVID-19 patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
