Iam 56 Yrs Old Man And I Had Undergone TURP

Iam 56 yrs old man and i had undergone TURP operation, about anoe and half year ago, for treatment of my sweeling of prostate problem.
The operation was successful, but after that operation i am facing another problem of dripping of urine.
The problem of dripping of urine was severe after the operation, but after taking some medicine, it reduced but still persist in lesser form.
Currently, i m not taking any medicine but i eagerly wants to get rid of this problem.
