Diagnostic accuracy of visual urethral mobility exam versus Q-Tip test: a randomized crossover trial

Abstract

The objective of the study was to compare the diagnostic accuracy of a visual urethral mobility examination (VUME) with a Q-Tip test in the assessment of urethral hypermobility. Subjects were randomized to a VUME or Q-Tip test first, followed by the alternate assessment. Outcomes included hypermobile, not hypermobile, or indeterminate. Hypermobility was defined as 30° or greater from the horizontal. Pain perception and test preference were assessed. For the 54 subjects, 61.1% demonstrated hypermobility on VUME vs 72.2% on the Q-Tip test (P = .39). Assessment of hypermobility was correlated between the 2 tools (ρ = 0.47, P = .001). Positive and negative predictive value, sensitivity, and specificity for VUME were 88%, 56%, 78%, and 71%, respectively, with a Q-Tip test as the reference standard. Mean pain score on visual analog scale was 0.72 for VUME and 3.15 for Q-tip test (P < .001). VUME was preferred by 83% of subjects. VUME is a diagnostic alternative to the Q-Tip test for the assessment of urethral hypermobility and is preferred by subjects.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Epigenetic Memory

Epigenetic memory refers to the heritable genetic changes that are not explained by the DNA sequence. Find the latest research on epigenetic memory here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Femoral Neoplasms are bone tumors that arise in the femur. Discover the latest research on femoral neoplasms here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
