Randomized Controlled Trial
Efficacy of lidocaine spray as topical anesthesia for outpatient rigid cystoscopy in women: a prospective, randomized, double-blind trial.
To determine the efficacy and feasibility of urethral lidocaine spray for rigid cystoscopy in female outpatients, compared with lidocaine gel for patient tolerance of pain. ⋯ Lidocaine spray and lidocaine gel produce similar anesthetic effects in women undergoing rigid cystoscopy. However, concerns about the mild discomfort associated with delivery of the spray need to be resolved through future technical improvement before it gains widespread use.
