Urethral stricture. To pass urine?

I am 30 year old. 1 year ago I was diagnosed with kidney stones, 5.7 mm,4mm, 6.2mm, 4.2mm, 5mm, they were all passed. Through urine...again after 6 month kidney stones reoccurred..of size 4mm, 3mm 5mm and they were passed again through urine ,soon after that my urine start causing me pain while peeing. And urine stream started bifurcation. And I have to apply pressure to pass my urine than I visited.again to urologist..he told me some tests uroflometry, rcg mcu. After seeing reports they diagnosed urethral stricture. And they opened the blockage through dilation. Now after 6 month I am facing same problem again .my urine starts bifurcation and causing me little pain while passing urine. And some times. I have to apply pressure to pass urine
