Clinical Outcomes and Safety of Modified Prostatic Urethral Lift Using a Zero-Angle Firing and Needle-Guided Puncture Technique for BPH

For millions of men as they age, a common and frustrating problem arises: the prostate gland, a small organ sitting just below the bladder, slowly grows larger. This growth, known as benign prostatic hyperplasia, squeezes the tube that carries urine out of the body. The result is a struggle to start urinating, a weak stream, and the constant, urgent need to visit the bathroom, often in the middle of the night. While doctors can treat this with medication, those drugs do not work for everyone, and they can have side effects. For those who need more help, surgery has long been the standard solution. However, traditional surgeries often involve cutting away tissue or using heat, which can lead to significant bleeding or permanently change how a man experiences sexual function. In recent years, a less invasive approach called the prostatic urethral lift has offered a gentler alternative. Instead of removing tissue, this method uses tiny implants to hold the enlarged prostate lobes open, like pinning back a curtain to clear a doorway, allowing urine to flow freely again.

Despite its promise, this lifting technique has faced a specific hurdle when treating the very bottom part of the prostate, near the bladder. In that tight space, the angle required to place the implants can be blocked by the pubic bone, making it difficult for surgeons to position their tools correctly. Sometimes, the needle meant to anchor the implant hits the bone instead of the tissue, or the surgeon simply cannot get a good grip. To solve this, a team of urologists in China developed a modified way to perform the procedure. They changed the angle of approach and added a manual technique to guide the needle, aiming to make the surgery smoother and more reliable for patients with difficult anatomy. Their goal was to see if this new method could safely relieve symptoms without the usual risks or the need for difficult positioning.

The researchers tested this new approach on twelve men who were suffering from significant urinary symptoms. All the participants were between fifty and eighty years old and had prostates of a moderate size. Before the surgery, these men filled out detailed questionnaires about their urinary habits and quality of life, and their doctors measured how fast they could urinate and how much urine was left in their bladders after they finished. The surgery itself was performed under general anesthesia. For most of the prostate, the surgeons used the standard method. However, when they reached the bottom section where the bone gets in the way, they switched to their modified technique. Instead of trying to angle the tool sideways, they kept it straight and centered. They then used their hands to gently press and guide the needle through the tissue to ensure it reached the right spot before deploying the tiny implant. This simple adjustment was designed to avoid the bone and ensure the implant was placed securely.

The results of this small study were encouraging. Every single one of the twelve procedures was completed successfully without the need to switch to a different type of surgery. The entire operation took an average of twenty-seven minutes, and on average, the surgeons placed about four and a half implants per patient. In the days following the surgery, most men experienced some blood in their urine, which is a common and expected reaction that cleared up within a week. About half of the men felt some urgency or discomfort when urinating, but these symptoms were mild and manageable. Crucially, no one developed a serious infection, a narrowing of the urethra, or required a second surgery. One man needed a temporary catheter to help him urinate, but he recovered fully. The most important finding was how quickly and effectively the men felt better. Within three months, the average score for urinary symptoms dropped dramatically, moving from a level that caused major distress to a level that was barely noticeable. The men also reported a much higher quality of life, and the speed at which they could urinate nearly doubled.

Perhaps just as important as the relief of symptoms was what did not change. The study carefully tracked the men's sexual health, specifically their ability to achieve an erection, and found that it remained completely stable. The scores for sexual function before the surgery were the same as they were three months and one year after the procedure. This confirms that the new technique, like the standard version, preserves sexual function, which is a major advantage over traditional surgeries that often cause retrograde ejaculation or erectile issues. The improvements in urinary flow and symptom relief held steady even a full year after the operation, suggesting that the fix is durable. The researchers noted that while the amount of urine left in the bladder after urination did decrease, the change was not statistically significant, likely because the numbers varied so much from person to person in this small group.

This study suggests that the modified technique is a safe and effective way to perform the prostatic urethral lift, particularly for the challenging area near the bottom of the prostate. By keeping the tool straight and using manual guidance, the surgeons were able to place the implants reliably without hitting the bone or causing complications. The men in the study saw rapid and lasting relief from their urinary problems without losing their sexual function. However, because this was a small study involving only twelve men and a single surgeon, the findings are preliminary. The authors emphasize that larger studies comparing this new method directly to the standard technique are needed to confirm these results and to see if the benefits hold true for a wider range of patients. For now, this work offers a promising refinement to an existing procedure, giving doctors a new tool to help men breathe easier and live more comfortably.
