An urethral probe comprised of a generally inflexible rod having a length of about 14 to 20 centimeters, extremely smooth surfaces and including a bulbous tip approximately one centimeter in length, an enlarged central portion of approximately 0.5 centimeters in diameter and a rounded terminal end portion. The probe is preferably of molded plastic, packaged in a sterile individual wrapper and disposed of after a single use. Calibrations in hypoallergenic ink assist the doctor or technician in the performance of a "Q-tip test" for measuring the urethral length, for evaluating the tone of the patient's sphincter, i.e., the trigone of the bladder, and for detecting the amount of change in the urethral vesicle angle incident to the diagnosis and evaluation of urinary stress incontinence. |
