Enlarged prostate Benign prostatic hyperplasia (BPH), also known as an enlarged prostate, is a condition that affects millions of men worldwide. The prostate is a small, walnut-sized gland that sits just below the bladder and helps produce semen. BPH occurs when the prostate enlarges and puts pressure on the urethra, the tube that carries urine from the bladder out of the body. This can cause urinary problems such as difficulty urinating, weak stream, dribbling, urgency, frequency, and waking up at night to urinate. While BPH does not usually lead to cancer, it can be uncomfortable and inconvenient. Interventional radiology offers a minimally invasive treatment option for men with BPH. Through keyhole surgery called transurethral resection of the prostate (TURP) or through a needle inserted through the skin into the urethra (transurethral needle ablation) Enlarged prostate, doctors are able to remove excess tissue in or around the prostate. These procedures help make urination easier, reduce nighttime trips to the bathroom, and improve the quality of life for many patients. TURP is more common but generally has fewer side effects than TUNA. Transurethral resection of the prostate (TURP): Most often used for men who have benign prostatic hypertrophy but have a narrowing of their urethra and/or troublesome symptoms like frequent urination or obstruction during ejaculation; though not used often today because newer therapies like TUNA are available. Transurethral needle ablation (TUNA): A surgical procedure that involves inserting needles into the walls of the prostate via the tip of your penis, then heating them up so they cut off tiny pieces; this is less risky than TURP and may provide some relief for those who don't want surgery or live too far away from a hospital. However, one drawback is that the removal of tissue doesn't address other causes of BPH, so it's only effective for about 50% of patients. Another drawback is that TUNA can sometimes leave scarring inside the prostate and affect sexual function. To avoid these potential complications, both TURP and TUNA require general anesthesia before the procedure begins. Side effects of either method are similar and include a burning sensation after urination, blood in urine or semen, discharge from the penis, fever over 100 degrees Fahrenheit, feeling faint or dizzy, increased thirst, and darkening of stool. If you experience any concerning side effects after surgery - no matter which type you had - contact your doctor immediately. After surgery most men will need catheterization until normal urinary flow returns; catheters can be left in place for up to 2 weeks before being removed.
