Kidney failure can be a life-changing event, leaving individuals with tough choices about their treatment options. While many may rely on dialysis, some fortunate folks can receive a kidney transplant, which usually leads to a better quality of life. Sadly, there aren't enough kidneys from deceased Donors to meet the demand. As a result, many countries are encouraging living kidney donations from healthy individuals. However, just like with any medical procedure, there can be risks involved. One that has recently come to light is testicular pain that some male kidney donors experience after their surgery.
Kidney Transplants
UnderstandingWhen someone’s kidneys fail, they can no longer filter waste from their blood effectively. This can lead to serious health issues. To counter this, people usually have two main options: kidney dialysis, a treatment that cleanses the blood but requires multiple sessions a week, or a kidney transplant, which involves receiving a healthy kidney from either a deceased or living donor.
Many medical professionals consider kidney transplants to be the better option since they can improve a person's life for many years. If you've ever heard of people thinking about donating a kidney, it's usually because they want to help someone in need while being perfectly healthy themselves.
The Rise of Living Kidney Donation
With the growing need for kidney transplants, living donation has become increasingly popular. Unfortunately, the number of deceased donors hasn't kept pace with the rising demand for transplants. As a result, healthy individuals are often encouraged to step up as living donors.
Living kidney donation can be a great option, but it doesn't come without risks. One common concern that has popped up in recent discussions is a specific issue that some men face after donating—a pain in their testicles.
Testicular Pain: A Lesser-Known Risk
Researchers have noted that some men who donate a kidney report experiencing testicular pain, often on the same side as the surgery. This isn't just a random occurrence; studies have found that the pain typically appears a week or so after the nephrectomy (the fancy term for kidney removal), and could feel like dull aching or heaviness.
Interestingly, a few studies have suggested that this kind of pain might be more common among those who undergo laparoscopic surgery (a minimally invasive method) compared to open surgery, where the incision is larger. However, most research has focused solely on laparoscopic Surgeries, so we still have some mysteries to solve.
The Need for More Research
Given the emerging reports of testicular pain among living kidney donors, researchers decided to take a closer look. To gain better insight, they conducted a multicenter study involving a group of living kidney donors and a similar group of non-donors, keeping their baseline health in mind. This way, they could see if there were differences in experiences post-surgery.
Participants were followed up for several years after their donation or simulated donation (for non-donors), and researchers wanted to find out how many of them reported testicular pain during that time. They also wanted to know if the pain was unilateral (on one side) or bilateral (on both sides), and whether it was related to the type of surgery performed or the side of the nephrectomy.
Study Design and Participants
The researchers ran their study across 17 different transplant centers in Canada and Australia. They gathered data from kidney donors and nondonors over a decade-long period. Consent was obtained from everyone involved, ensuring that ethical standards were upheld.
The nondonors included individuals who were friends or family members of the donors, as well as those who had considered donation but didn’t go through with it for various reasons. The idea was to ensure both groups had similar health backgrounds.
Collecting Data
The study involved collecting a range of data from participants both before the surgery and during follow-ups. At the beginning, both donors and nondonors answered a questionnaire about their health, underwent some basic physical assessments, and provided lab samples for testing. Later, they completed a simple pain questionnaire to check in on their experiences with testicular pain.
The questionnaire also asked participants about any pain they might have felt in other areas, like their hands or eyes, so researchers could gauge any potential bias in recalling pain symptoms.
Statistical Analysis
To make sense of the data, researchers employed various statistical methods to compare the experiences of donors with those of nondonors. This included balancing out differences in baseline characteristics to ensure an accurate comparison.
Given the medical nature of the study, they used specialized software to conduct the analysis and calculate risk ratios. The ultimate goal was to determine any significant differences in the reports of testicular pain between the two groups.
Findings: Testicular Pain Rates
When analyzing the results, researchers discovered that a notable number of male donors—17.6%—reported experiencing testicular pain during follow-up. In contrast, only 2.3% of male nondonors reported similar issues. This suggests that kidney donation indeed comes with a higher risk of testicular discomfort afterward.
The majority of the reported pain was unilateral, meaning it affected only one side. Furthermore, a significant portion of the pain was located on the same side as the kidney that was removed.
Surgical Details Impacting Pain
The study looked into the different surgical methods used—laparoscopic versus open surgery—and how they affected the occurrence of testicular pain. Most of the male donors in the study underwent laparoscopic nephrectomy, which is usually less invasive. The findings indicated that testicular pain was indeed more common among those who had laparoscopic surgery compared to those who had open surgery.
While the exact reasons for this difference are still unclear, one possible explanation is related to the surgical approach and the division of certain veins during the procedure.
A Closer Look at Nephrectomy Sides
The researchers also wanted to examine whether there was a difference in reported testicular pain based on which kidney was removed—left or right. The results showed that there was no significant difference in pain reports between these two groups, which suggests that the side of nephrectomy might not be as important a factor as previously thought.
However, the complexities of human anatomy and surgical techniques still warrant further investigation to fully understand why some men experience this pain after surgery.
Comparing Risks Across Centers
Interestingly, testicular pain was reported by male donors across various transplant centers located in multiple regions. Most centers had at least some reports of testicular pain, but a couple of centers did not have any cases at all. This raises questions about potential variations in surgical techniques or care practices that could contribute to the outcomes experienced by the patients.
Pain Perception and Aftermath
Donors were also asked to describe their pain in their own words, and various descriptions emerged, from dull and sharp to tender and achy. Some even reported developing a hydrocele, which is a fluid buildup around the testicle—a condition that sometimes requires surgical repair.
Pain, when rated on a scale from one to ten, usually fell around three to four, indicating that while it was a concern, it wasn't off the charts in severity for most donors.
What Does This Mean for Kidney Donation?
The results of this study highlight an often overlooked aspect of living kidney donation: the risk of testicular pain. While many men might step forward to donate out of the goodness of their hearts, they may not be fully aware of this possible consequence.
As kidney transplant rates continue to rise, it’s essential for healthcare providers to communicate these risks clearly to potential donors. They should feel equipped with all the necessary information to make an informed decision.
Future Research Directions
Researchers stress the need for further studies to better define testicular pain as a complication of kidney donation. More data could help determine if there are specific factors—such as age or surgical technique—that could lessen the chance of developing this pain in the future.
Healthcare professionals and potential donors alike benefit from ongoing research to uncover the nuances of kidney donation. After all, understanding what donors can expect before, during, and after surgery can help make the experience smoother for everyone involved.
Conclusion
Living kidney donation is a critical option for those needing a transplant, but it is essential to recognize the potential risks. Whether you’re considering doing a good deed for a friend or loved one, make sure you’re aware of what could come after you make that generous choice.
Testicular pain, while not the first thing that comes to mind when discussing kidney donations, is an important issue that needs to be addressed. With more awareness and research, we can continue to improve the process of kidney donation and enhance the overall experience for all involved.
So go ahead, save a life with your spare kidney, but remember—check yourself before you wreck yourself… or at least check if your testicles might want to join the conversation.

Title: Testicular pain after living kidney donation: Results from a multicenter cohort study
Abstract: BackgroundSome men who donate a kidney have reported testicular pain after donation; however, attribution to donation is not clear as no prior studies included a comparison group of nondonors. ObjectiveTo examine the proportion of male donors who reported testicular pain in the years after nephrectomy compared to male nondonors with similar baseline health characteristics. Design, Participants, and SettingWe enrolled 1042 living kidney donors (351 male) before nephrectomy from 17 transplant centers (12 in Canada and 5 in Australia) from 2004-2014. A concurrent sample of 396 nondonors (126 male) was enrolled. Follow-up occurred until November 2021. MeasurementsDonors and nondonors completed the same schedule of measurements at baseline (before nephrectomy) and follow-up. During follow-up, participants completed a questionnaire asking whether they had experienced new pain in their eyes, hands, or testicles; those who experienced pain were asked to indicate on which side of the body the pain occurred (left or right). The pain questionnaire was completed by 290 of 351 male donors (83%) and 97 of 126 male nondonors (77%) a median of 3 years after baseline (interquartile range 2, 6). MethodsInverse probability of treatment weighting on a propensity score was used to balance donors and nondonors on baseline characteristics. After weighting, the nondonor sample increased to a pseudo sample of 295, and most baseline characteristics were similar between donors and nondonors. ResultsAt baseline, donors (n=290) were a mean age of 49 years; 83% were employed, and 80% were married; 246 (84.8%) underwent laparoscopic surgery and 44 (15.2%) open surgery; 253 (87.2%) had a left-sided nephrectomy and 37 (12.8%) a right-sided nephrectomy. In the weighted analysis, the risk of testicular pain was significantly greater among donors than nondonors: 51/290 (17.6%) vs. 7/295 (2.3%); weighted risk ratio, 7.8 (95% CI, 2.7 to 22.8). Donors and nondonors did not differ statistically in terms of self-reported eye pain or hand pain. Among donors, the occurrence of testicular pain was most often unilateral (92.2%) and on the same side as the nephrectomy (90.2%). Testicular pain occurred more often in donors who had laparoscopic vs. open surgery: 48/246 (19.5%) vs. 3/44 (6.8%) but was similar in those who had a left-sided vs. right-sided nephrectomy: 44/253 (17.4%) vs. 7/37 (18.9%). LimitationsParticipants recalled their symptoms several years after baseline, and we did not assess the timing, severity, or duration of pain or any treatments received for the pain. ConclusionUnilateral testicular pain on the same side of a nephrectomy is a potential complication of living kidney donation that warrants further investigation. Clinicaltrial.gov recordNCT00936078
