Urethrography Ascending

Ascending urethromorphia (synonym - urethrorefthia):

Definition

*technique for x-ray examination of the posterior part of the urethra.* You came across this technique when taking a general urine test according to the “stress” sampling rules, where you collected urine in a separate container, after having previously urinated directly in the office or into your panties in the clinic. Then have you ever wondered why exactly **a portion of urine** that you have isolated yourself is used for analysis? But because sterility is important for research!
