Use of Lidocaine 2% Gel Does Not Reduce Pain during Flexible Cystoscopy and Is Not Cost-Effective. Urol J. 2015; 12(5):2362-51735-1308http://hdl.handle.net/10668/2522Comparative Study; Journal Article; Observational Study;PURPOSE To compare the use of lubricant gel with lidocaine versus lubricant gel without anesthetic in flexible cystoscopy in terms of pain and tolerability. MATERIALS AND METHODS In this observational non-randomized study, 72 patients were divided into two groups. Group 1 included 38 patients in whom lidocaine gel 2% was used and group 2 included 34 patients in whom lubricant gel without anesthetic was administered. The main variables analyzed were score in visual analogue scale (VAS) and score in Spanish Pain Questionnaire (SPQ). Student's t-test and Chi-square test were used to compare differences between 2 groups. The P values < .05% were considered statistically significant. RESULTS Mean age of patients in group 1 was 64.50 ± 12.39 years and 67.79 ± 10.87 years in group 2 (P = .23). The distribution according to sex was 29 men and 9 women in group 1 and 25 men and 9 women in group 2 (P = .78). The total VAS score was 2.21 ± 2.05 in group 1 versus 1.59 ± 1.61 in group 2 (P = .16). In the SPQ, the current intensity value was 1.82 ± 0.86 in group 1 versus 1.53 ± 0.74 in group 2 (P = .14), and the total intensity value was 1.92 ± 1.86 in group 1 versus 1.03 ± 1.75 in group 2 (P = .04). The cost of gel with lidocaine is 1.25 euro and gel without anesthetic 0.22 euro. CONCLUSION The use of lidocaine gel does not produce benefit in terms of pain relief in flexible cystoscopy and also is costly.enCystoscopyMethodsAdverse effectsDiagnosisAnestheticsLocalLidocaineTherapeutic useTreatment outcomePain prevention & controlPain measurement.Anestésicos localesCistoscopíaLidocaínaDimensión del dolorEncuestas y cuestionariosMedical Subject Headings::Chemicals and Drugs::Chemical Actions and Uses::Pharmacologic Actions::Physiological Effects of Drugs::Central Nervous System Depressants::Anesthetics::Anesthetics, LocalMedical Subject Headings::Health Care::Health Care Economics and Organizations::Economics::Costs and Cost Analysis::Cost-Benefit AnalysisMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Surgical::Endoscopy::CystoscopyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Therapeutics::Drug Therapy::Drug Therapy, CombinationMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Chemicals and Drugs::Pharmaceutical Preparations::Dosage Forms::Colloids::GelsMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Chemicals and Drugs::Organic Chemicals::Amides::Anilides::Acetanilides::LidocaineMedical Subject Headings::Chemicals and Drugs::Chemical Actions and Uses::Specialty Uses of Chemicals::LubricantsMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Middle AgedMedical Subject Headings::Phenomena and Processes::Musculoskeletal and Neural Physiological Phenomena::Nervous System Physiological Phenomena::Nervous System Physiological Processes::Sensation::PainMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Neurological::Neurologic Examination::Pain MeasurementMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Research Design::Single-Blind MethodMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::QuestionnairesMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Agedresearch article26571322open access1735-546X
