Dear Anthony,
The discomfort that you described following your vasectomy occurs often following this procedure. However the lump that you describe could be due to several different entities. The two most common causes would be a hematoma or a sperm granuloma. Hematomas are just a result of the surgical dissection and usually soon dissipate. Sperm granulomas form when sperm leak from the testicular end of the vas. Sperm granulomas are rarely symptomatic, but in a few individuals may result in a painful lump.
It is highly unlikely that a bladder stone would be related to your vasectomy. Bladder stones are typically due to an obstructive uropathy that leads to urinary stasis. Bladder stones can then form when the bladder is not properly draining. A bladder outlet obstruction, most likely from benign prostatic hypertrophy, would be consistent with your symptoms of having to get up at night to urinate, foul smelling urine, and bladder stones. It is imperative that you follow your doctor’s suggestions and undergo the tests that he has recommended to avoid a serious urinary tract infection. The pain that you describe in your testicles could arise from a number of sources and it is extremely difficult for me to help you without a full urologic exam. You need to be seen by a urologist as soon as you can schedule an appointment.
