Tear-Nasal Test

**Nasolacrimal** test is a new method of conducting a laboratory tubular test.

To carry out the test, a retrograde Seldinger catheterization of the pelvis and nephrostomy drainage cups is first carried out - when the urethral catheter is passed through the bladder (vesical urine separation), but is discharged into the pelvis - pathanomy. This manipulation is performed by a urologist-nephrologist under ultrasound control.
