Patients will be randomized to 2 groups: (1) Patients who will be requested to urinate while catheterising the urethra to its full length; (2), Patients who will be requested to lie while catheterising the urethra, without further instructions from the medical professional. In both groups, prior to catheterisation, 10 ml of lidocaine gel will be inserted into the urethra. The randomization technique will be employed by a computerized random number generator.
