Is there any chance of cancer if my urine gets stuck or trapped after urination?

Hi doctor,

I am 25 years old. For the last four years, I have been facing frequent urination problems. I went to the urologist he told me to do a urine culture and sensitivity and urine microscopy test, but at that time test was normal, and my blood test was also normal. But the problem continued, so again I visited a urologist. My problem increased as I had constipation, and while urinating, 90 percent of urine comes out from the penis, whereas 30 to 20 percent of urine gets stuck. Hence, the doctor did a cystoscopy and told you might have chronic cystitis, gave me a tablet, and told me that the problem would be resolved within three months, but my pain continued again after three months. I have recently visited another hospital and underwent the following tests: kidney function test panel, urine microscopy, urine aerobic bacterial culture and sensitivity, ultrasound kyn with prostate with PVRU, and uroflowmetry PVRU, but all results are normal. But I did not receive any solution to my problem yet. Please help.

Hi doctor,

Thanks for your reply. I do not have a burning sensation always. I took RGU and MCU tests four years back, but at that time, my urine was not getting stuck or trapped after urination. Is there any chance of cancer? I also did masturbation. Is masturbation related to this? Please help.
