A catheter for insertion into a patient's urethra is provided, comprising: (a) first and second tubular members having such a diameter for enabling drainage of physiological fluids therethrough, the first and second tubular members being interconnected by means of a connecting tube of substantially smaller diameter; (b) an inflatable balloon attached to the second tubular member, the inflatable balloon being in fluid communication with the connecting tube. The inflatable balloon is inserted to the patient's urinary bladder so as to locate the second tubular member substantially within the patient's prostatic urethra such that the connecting tube is held by the patient's sphincter. Further according to the present invention there is provided a guiding element for insertion through the catheter, including: (a) a substantially elongated tubular member having a hollow, the elongated tubular member having a closed end for insertion through the patient's urethra and an open end for connection to an external inflating element; (b) an inflatable balloon attached to the elongated tubular member, the inflatable balloon being in fluid communication with the hollow of the tubular element, the inflatable balloon for inflation against the catheter so as to effectively fix the guiding element to the catheter.
