Description

Parekattil et al developed a model for helping to determine if vasoepididymostomy will be required for vasectomy reversal. The authors are from the Cleveland Clinic.


 

Parameters:

(1) age in years

(2) number of years since vasectomy operation

 

prediction score =

= (0.31 * (age in years)) + (0.94 * (number of years since vasectomy))

 

Interpretation:

• minimum score: around 5.6

• maximum score: > 70

• The higher the score the more likely a vasoepididymostomy will be required.

 

Predictive Score

Therapeutic Option

< 20

bilateral vasovasotomy

>= 20

unilateral or bilateral vasoepididymostomy

 

Performance:

• The sensitivity is 100% and specificity 59%.

• The area under the ROC curve is 0.8.
