Perioperative Outcomes and Complications of Primary versus Revision Penile Prosthesis Surgery: A Retrospective Single-Center Cohort Study
This retrospective single-center study demonstrates that while revision penile prosthesis surgery requires significantly longer operative time and shows a non-significant trend toward higher complication rates compared to primary implantation, these findings underscore the need for careful patient counseling and resource planning even within experienced programs.

For many men, the inability to achieve an erection is a source of deep personal distress that does not respond to medication or lifestyle changes. When these conservative options fail, the medical community has long relied on a surgical solution: the inflatable penile prosthesis. This device is a mechanical implant placed inside the penis, consisting of fluid-filled cylinders that can be inflated to create rigidity and deflated to return to a natural state. It is considered the gold standard for restoring function, offering a reliable outcome for patients and their partners. However, like any mechanical system, these devices can encounter problems over time. Infections, mechanical breakdowns, or shifts in position can necessitate a second operation to repair or replace the original implant. While the initial surgery is well understood, the process of fixing a failed device is technically more difficult because scar tissue and altered anatomy make the work harder. Understanding exactly how these revision surgeries compare to the first-time procedures is crucial for planning care and setting realistic expectations for patients.
A team of researchers at the University Hospital Schleswig-Holstein in Lübeck, Germany, set out to examine this specific challenge. They looked back at records from a newly established surgical program that began in April 2024 and continued through July 2026. During this period, the hospital performed 108 penile prosthesis surgeries in total. The team separated these into two groups: 74 patients receiving their first implant and 34 patients undergoing a revision to fix a previous device. Every procedure was performed by the same experienced surgeon, ensuring that the results reflected the differences between the surgeries themselves rather than variations in surgical skill. The researchers meticulously tracked how long each operation took, how long patients stayed in the hospital, and what complications arose, such as bleeding, infection, or device failure.
The study revealed a clear and significant difference in the time required for the two types of surgery. The initial implantation took a median of 56 minutes, whereas the revision surgeries took a median of 78 minutes. This difference persisted even after the researchers accounted for factors like the patient's age, body weight, and the presence of Peyronie's disease, a condition that causes curvature of the penis. On average, the revision surgeries required nearly 20 additional minutes of operating time. This extra time is likely due to the need to carefully navigate scar tissue and distorted anatomy left behind by the first surgery, which makes the work more intricate and demanding. The length of the hospital stay was also slightly longer for the revision group, though the time patients spent with catheters and drains did not differ between the two groups.
When it came to complications, the picture was more nuanced. The researchers found that revision surgeries had a higher rate of problems overall, with about 32 percent of revision patients experiencing some form of complication compared to 20 percent of those with primary implants. Major complications, which are serious enough to require significant medical intervention, occurred in roughly 12 percent of revision cases versus 4 percent of primary cases. However, because the number of patients in the revision group was relatively small, these differences did not reach the threshold of statistical certainty. In other words, while the numbers suggest revision is riskier, the study could not definitively prove that the risk is higher based on this specific group of patients. One notable finding was that the removal of the device, known as explantation, happened only in the revision group, affecting two patients, while no primary implants were removed.
The researchers also observed that their specific protocol for managing fluid drainage after surgery appeared to be effective. They kept drains in place for 48 to 72 hours, a duration slightly longer than what is common in other studies, to prevent blood from collecting around the new implant. This approach seemed to work well, as the rate of infection remained low, occurring in only one patient who also had diabetes. The study concludes that while revision surgery is undeniably more time-consuming and shows a trend toward more complications, it remains a viable procedure. The findings suggest that surgeons should schedule extra time for these operations and counsel patients that the path to fixing a failed device is inherently more complex than the initial installation. The authors emphasize that these results, drawn from a single center with a specialized team, serve as a strong starting point for understanding the realities of revision surgery, but larger studies involving more patients are needed to confirm these patterns with greater certainty.
