Johns Hopkins: Prostate on BPH treatment options: "Possible Complications
While minimally invasive procedures for BPH are often associated with less severe complications than TURP, they still can cause side effects, including the following:
* Difficult or painful urination. These problems are common in the first days after the catheter is removed, but they typically improve after a week or two. If urinating is extremely painful or does not improve, contact your urologist.
* Blood in the urine. A small amount of blood that lends a pinkish hue to your urine may cause you some anxiety but is common for up to three days after the procedure. However, if the bleeding is heavy, lasts more than a few days, or causes blood clots that block the flow of urine, call your urologist.
* Urinary tract infections. These infections usually result from catheterization; the longer you have a catheter, the higher your risk of infection. To reduce this risk, antibiotics are often prescribed either after the procedure or after catheter removal.
* Urinary retention. A small number of BPH patients are unable to urinate on their own after catheter removal and may require a longer period of catheterization. If this happens, contact your doctor.
* Sexual dysfunction. In general, the rates of sexual dysfunction are thought to be lower with TUNA and TUMT than with TURP. Nonetheless, men can experience retrograde ejaculation (ejaculation into the bladder instead of through the penis) after TUNA and TUMT. In one study, one in five men reported retrograde ejaculation after TUMT. However, most studies show that TUNA and TUMT have no major adverse effects on sexual function.
* Severe abdominal pain or a high fever. Contact your doctor if you experience either of these symptoms."
