Differential Changes Across Sexual Function Domains After Urethroplasty: A Prospective Study

For many men, the ability to urinate without obstruction is a fundamental aspect of health, yet when the tube that carries urine out of the body becomes narrowed by scar tissue, it can disrupt life in profound ways. This narrowing, known as a urethral stricture, often results from past injuries, infections, or medical procedures, and it forces the body to work harder to push urine through a blocked passage. While surgeons have long been able to repair these blockages with high success rates, restoring the physical flow of urine, a different question has lingered: does fixing the plumbing also affect the man's sexual life? Sexual function is a complex landscape involving the ability to achieve an erection, the satisfaction felt during intimacy, and the underlying desire for connection. Understanding how a major reconstructive surgery impacts these delicate aspects of life is crucial, not just for medical outcomes, but for the overall well-being of the patient.

A team of researchers in Vietnam set out to map this territory by following men who underwent urethroplasty, a surgical procedure designed to rebuild the damaged section of the urethra. They recruited patients from a single hospital between August 2024 and August 2025, focusing on those who agreed to share detailed information about their sexual health before the operation and again six months after. To get a clear picture, the researchers used a well-known questionnaire that breaks sexual health into five distinct areas: the physical ability to get and keep an erection, satisfaction with the act of intercourse, the ability to reach orgasm, sexual desire, and overall satisfaction with one's sex life. By comparing the scores from before the surgery to those taken six months later, the team could see exactly how the body and mind responded to the reconstruction.

The results revealed a story of mixed outcomes, where the surgery successfully restored the urinary tract but left a temporary mark on sexual function. Six months after the operation, the average score for erectile function dropped noticeably, moving from a high level of function before surgery to a lower level afterward. A similar decline was seen in how satisfied men felt during intercourse and in their general sexual desire. However, the ability to reach orgasm and the feeling of overall satisfaction with one's sex life remained largely unchanged, suggesting that the surgery affected specific parts of sexual health more than others. The researchers noted that these changes were significant, but they also emphasized that six months is a relatively short time in the life of a healing body, and these numbers might shift as recovery continues.

Age played a decisive role in how men experienced these changes. The study found that men aged sixty and older faced a steeper drop in their ability to achieve erections compared to their younger counterparts. While both groups saw a decrease, the older group started with slightly lower scores and ended with a much sharper decline, losing more ground in their erectile function than the younger men. This suggests that the aging body may be less resilient to the stress of major surgery or that age-related factors make recovery of sexual function more challenging. In contrast, the length of the scar tissue that was removed did not seem to independently dictate how sexual function changed; whether the blockage was short or long, the impact on sexual scores was not significantly different once other factors were taken into account.

The type of surgery performed also told a different part of the story. There are two main ways surgeons repair the urethra: one involves cutting out the damaged section and sewing the healthy ends together, while the other involves adding a piece of tissue, often taken from the inside of the cheek, to widen the channel. The study found that men who underwent the procedure where tissue was added reported a more favorable outcome regarding their satisfaction with intercourse compared to those who had the ends sewn together. While both groups saw a drop in erectile function, the group with the added tissue maintained a higher level of satisfaction during the act itself. This hints that the specific technique used might influence how a man feels about his sexual experience, even if the physical mechanics of the erection are affected similarly in both groups.

Ultimately, this research highlights that while urethroplasty is a highly effective treatment for urinary blockages, it is not without consequences for sexual health in the months immediately following the operation. The findings suggest that doctors and patients should have open conversations about these potential changes, particularly for older men who may be at higher risk for a decline in erectile function. The study does not claim that these changes are permanent, noting that sexual function can improve over longer periods, but it does establish that the first six months can be a time of adjustment. By identifying which factors, such as age and surgical technique, are linked to specific outcomes, the research provides a clearer roadmap for managing expectations and supporting patients as they navigate recovery.
