A disposable male catheter system includes a catheter to be inserted into the urethra of the penis. The catheter has a proximal end to discharge urine into a bag, a distal end to be inserted into the bladder and holes formed in the distal end to receive urine. A sleeve is disposed on and is harder than the catheter. The sleeve is slid along with the catheter within the urethra to a clamping region. A clamp is clamped over the penis at the clamping region to prevent urine from leaking around the catheter.
