Why are hospitals moving to Transperineal Prostate Biopsy?
Introduction Prostate cancer is one of the most common cancers among men worldwide. Accurate diagnosis depends on prostate biopsy procedures that allow clinicians to collect tissue samples for histopathological analysis. Hospitals are rapidly shifting from the traditional transrectal (TR) to the transperineal (TP) biopsy for prostate cancer diagnosis primarily because the TP approach eliminates the risk of serious infection/sepsis by avoiding the needle passage through the rectum. This shift is fueled by increasing antibiotic resistance in rectal flora and improved technology that allows TP biopsy to be performed in an office setting under local anesthesia. For decades, the transrectal ultrasound-guided prostate biopsy was the most widely used technique. However, growing concerns regarding infection risk, diagnostic limitations, and healthcare costs have prompted hospitals to reconsider their biopsy pathways. Lets understand why are hospitals moving to Transperineal Prostate Biopsy. What are the challenges faced by hospitals? Hospitals using the traditional transrectal biopsy method face several clinical and operational challenges. 1. Infection and Sepsis Risk Transrectal biopsy involves passing a biopsy needle through the rectal wall, exposing patients to bacteria present in the rectum. Studies show that this approach can lead to urinary tract infections, prostatitis, and sepsis in some patients. Infection rates following transrectal biopsy have been reported as high as 5–7% in some cases, even when antibiotic prophylaxis is used. Sepsis rates following TR biopsy have been reported between 0.4% and 9.8%, making infection one of the most significant complications of the procedure. These complications increase hospital admissions, antibiotic usage, and healthcare costs. 2. Limited access to certain areas of the Prostate Another limitation of the transrectal approach is the difficulty in accessing the anterior region of the prostate. Missing these lesions can delay diagnosis and treatment. Studies indicate that transrectal biopsy can miss cancers located in these areas, with approximately 10% of prostate cancers occurring exclusively in the anterior prostate. 3. Rising healthcare costs Post-biopsy infections can lead to: These complications significantly increase the cost burden for healthcare systems. Shift towards Transperineal Biopsy To address the above mentioned challenges, hospitals have increasingly adopted the transperineal biopsy technique. Instead of passing through the rectum, the biopsy needle is inserted through the perineum, allowing direct access to the prostate while avoiding rectal bacteria. This change in approach has demonstrated several clinical and operational advantages. What are the clinical benefits of Transperineal Biopsy? Transperineal prostate biopsy is increasingly preferred over the traditional transrectal approach because it offers better diagnostic accuracy and improved patient safety. Below are the main clinical benefits of transperineal biopsy. Some of the clinical benefits of Transperineal Biopsy are as follows. 1. Significantly lower Infection Risk One of the most important advantages of the transperineal approach is its reduced infection risk. Research shows that transperineal biopsy is associated with up to 77% lower risk of hospitalisation due to infectious complications compared with transrectal biopsy. Some studies report infection rates below 1% and sepsis rates under 0.5% following transperineal biopsy. In clinical trials, patients undergoing transperineal biopsy experienced zero infections, while infections were observed in the transrectal group. Because the needle does not pass through the rectum, exposure to bacteria is greatly reduced. 2. Improved Cancer Detection The transperineal approach allows clinicians to sample all regions of the prostate, including the anterior and apical zones that are difficult to reach via the transrectal route. This improves diagnostic accuracy and helps clinicians detect clinically significant prostate cancers earlier. Studies also indicate that the cancer detection rate is comparable or slightly better than the traditional approach. 3. Reduced Antibiotic Dependence Because the infection risk is much lower, transperineal biopsy can often be performed without prophylactic antibiotics, reducing antibiotic resistance concerns. This is particularly important in modern healthcare systems that are trying to reduce unnecessary antibiotic use. What are the operational benefits for hospitals? Beyond clinical advantages, the transperineal approach also improves operational efficiency. 1. Standardised Biopsy Workflow Modern transperineal systems use grid-based or freehand guidance devices, allowing clinicians to perform systematic sampling with greater precision. 2. Day Case Procedure The procedure can often be performed under local anaesthesia, enabling same-day discharge for most patients. 3. Reduced Complication Costs Lower infection rates reduce: This makes the procedure more cost-effective for healthcare providers. Case Example: Hospital Implementation Hospital Profile Previous Method Transrectal ultrasound guided biopsy and the challenges includes: Implementation The hospital transitioned to transperineal ultrasound-guided biopsy using a stepper stabiliser and biopsy grid system. Let’s analyze the results after implementation. Metric Before (TR) After (TP) Infection Rate ~2–3% <1% Sepsis Cases Occasional Rare Anterior Cancer Detection Limited Improved Hospital Admissions Higher Reduced Antibiotic Use Required Minimal What are the economic impacts of Transperineal Biopsy? International clinical guidelines are increasingly supporting the transperineal approach. Lower infection rates significantly reduced hospital costs associated with post-biopsy complications. In addition, streamlined biopsy workflows allowed the department to increase procedural capacity. For example, European urology guidelines recommend transperineal biopsy as a preferred method due to its lower risk of infectious complications. Similarly, health technology assessments have concluded that transperineal biopsy systems can be cost-effective options for diagnosing prostate cancer. Conclusion The transition from transrectal to transperineal prostate biopsy represents a significant advancement in prostate cancer diagnostics. Hospitals are adopting this approach because it offers: As clinical evidence continues to grow, the transperineal biopsy technique is rapidly becoming the preferred standard for prostate biopsy procedures worldwide.
