Surgeons Perform First Human Bladder Transplant

Surgeons in Southern California have performed the first human bladder transplant, introducing a new, potentially life-changing procedure for people with debilitating bladder conditions.

The operation was performed earlier this month by a pair of surgeons from the University of California, Los Angeles, and the University of Southern California on a 41-year-old man who had lost much of his bladder capacity from treatments for a rare form of bladder cancer.

“I was a ticking time bomb,” the patient, Oscar Larrainzar, said on Thursday during a follow-up appointment with his doctors. “But now I have hope.”

The doctors plan to perform bladder transplants in four more patients as part of a clinical trial to get a sense of outcomes like bladder capacity and graft complications before pursuing a larger trial to expand its use.

Dr. Inderbir Gill, who performed the surgery along with Dr. Nima Nassiri, called it “the realization of a dream” for treating thousands of patients with crippling pelvic pain, inflammation and recurrent infections.

“There is no question: A potential door has been opened for these people that did not exist earlier,” said Dr. Gill, the chairman of the urology department at U.S.C.

Pushing the Envelope

Until now, most patients who undergo a bladder removal have a portion of their intestine repurposed to help them pass urine. Some receive an ileal conduit, which empties urine into a bag outside the abdomen, while others are given a so-called neobladder, or a pouch tucked inside the body that attaches to the urethra and allows patients to urinate more traditionally.

But bowel tissue, riddled with bacteria, is “inherently contaminated,” Dr. Gill said, and introducing it to the “inherently sterile” urinary tract leads to complications in up to 80 percent of patients, ranging from electrolyte imbalances to a slow reduction in kidney function. The loss of the intestinal segment can also cause new digestive issues.

Dr. Despoina Daskalaki, a transplant surgeon at Tufts Medical Center who was not involved in the new procedure, said advances in transplant medicine (from critical life-sustaining organs, like hearts and livers, to other body parts, like faces, hands, uteri and penises) had led doctors to start “pushing the envelope.”

“They’re asking: ‘Why do we have to put up with all the complications? Why don’t we try and give this person a new bladder?’” Dr. Daskalaki said.

In late 2020, Dr. Nassiri was in his fourth year of residency at the University of Southern California when he and Dr. Gill sat down in the hospital cafeteria to begin brainstorming approaches. After Dr. Nassiri began a fellowship on kidney transplantation at U.C.L.A., the two surgeons continued working together across institutions to test both robotic and manual techniques, practicing first on pigs, then human cadavers, and finally, human research donors who no longer had brain activity but maintained a heartbeat.

One of the challenges of transplanting a bladder was the complex vascular infrastructure. The surgeons needed to operate deep inside the pelvis of the donor to capture and preserve a rich supply of blood vessels so the organ could thrive inside the recipient.

“When we’re removing a bladder because of cancer, we basically just cut them. We do it in less than an hour on a near-daily basis,” Dr. Gill said. “For a bladder donation, that is a significantly higher order of technical intensity.”

The surgeons also chose to conjoin the right and left arteries — as well as the right and left veins — while the organ was on ice, so that only two connections were needed in the recipient, rather than four.

When their strategy was perfected in 2023, the two drew up plans for a clinical trial, which eventually would bring the world’s first recipient: Oscar.

An Ideal First Candidate

When Mr. Larrainzar walked into Dr. Nassiri’s clinic in April 2024, Dr. Nassiri recognized him. Almost four years earlier, Mr. Larrainzar, a husband and father of four, had been navigating end-stage kidney disease and renal cancer, and Dr. Nassiri helped remove both of his kidneys.

But Mr. Larrainzar had also survived urachal adenocarcinoma, a rare type of bladder cancer, and a surgery to resect the bladder tumor had left him “without much of a bladder at all,” Dr. Nassiri said. A normal bladder can hold more than 300 cubic centimeters of fluid; Mr. Larrainzar’s could hold 30.

Now, years of dialysis had begun to fail; fluid was building up inside his body. And with so much scarring in the abdominal region, it would have been difficult to find enough usable length of bowel to pursue another option.

“He showed up serendipitously,” Dr. Nassiri said, “but he was kind of an ideal first candidate for this.”

On a Saturday night earlier this month, Dr. Nassiri received a call about a potential bladder match for Mr. Larrainzar. He and Dr. Gill drove straight to the headquarters of OneLegacy, an organ procurement organization, in Azusa, Calif., and joined a team of seven surgeons working overnight to recover an array of organs from a donor.

The two brought the kidney and bladder to U.C.L.A., then stopped home for a shower, breakfast and a short nap. They completed the eight-hour surgery to give Mr. Larrainzar a new bladder and kidney later that day.

Dr. Nassiri said that kidney transplants can sometimes take up to a week to process urine, but when the kidney and bladder were connected inside Mr. Larrainzar, there was a great connection — “immediate output” — and his creatinine level, which measures kidney function, started to improve immediately. Mr. Larrainzar has already lost 20 pounds of fluid weight since the surgery.

The biggest risks of organ transplantation are the body’s potential rejection of the organ and the side effects caused by the mandatory immune-suppressing drugs given to prevent organ rejection. That is why, for Dr. Rachel Forbes, a transplant surgeon at Vanderbilt University Medical Center who was not involved in the procedure, the excitement is more tempered.

“It’s obviously a technical advance,” she said, but “we already have existing options for people without bladders, and without the downside of requiring immunosuppression.” Unless a patient is — like Mr. Larrainzar — going to be on those medications anyway, “I would be a little bit nervous that you would be exchanging some complications for others,” she said.

A new bladder transplant also does not have nerve connections in the recipient, so while it works well as a storage organ, doctors did not know whether Mr. Larrainzar would ever be able to sense a full bladder, let alone hold and empty it naturally. They spoke about catheters, abdomen maneuvers and eventually developing an on-demand bladder stimulator to help with the release.

But at a follow-up appointment on Thursday morning — just two days after Mr. Larrainzar was discharged from the hospital — Dr. Nassiri removed the catheter and gave him fluids, and Mr. Larrainzar immediately felt that he could urinate.

Dr. Nassiri called it a miracle, then phoned Dr. Gill, who was in a U.S.C. operating room, and exclaimed two words: “He peed!”

“No way! What the hell?” Dr. Gill said. “My jaw is on the floor.”

After finishing the surgery, Dr. Gill drove straight to U.C.L.A. and watched Mr. Larrainzar do it again.

“Of course, this is very, very early. Let’s see how everything goes,” Dr. Gill cautioned. “But it’s the first time he has been able to pee in seven years. For all of us, this is huge.”

Mr. Larrainzar, exhausted, smiled, and Dr. Nassiri brought him a bottle of mineral water to celebrate.

Aging-related joint disorder increasingly affects people under 40, study finds

Cases of gout are rising in younger individuals, according to a global study.

The condition, which is a type of inflammatory arthritis, steadily increased in people aged 15 to 39 between 1990 and 2021, researchers in China announced.

Although rates vary widely between countries, the total number of young people with the condition is expected to continue rising through 2035.

WEIGHT LOSS DRUGS COULD ADD YEARS TO AMERICANS’ LIVES, RESEARCHERS PROJECT

The study, published in the journal Joint Bone Spine, investigated 2021 data from the Global Burden of Disease (GBD), spanning 204 countries within the 30-year timeframe.

The data measured gout prevalence, incidence and years lived with disability, tracking global trends over time. The results showed a global increase across all three outcomes.

Prevalence and disability years increased by 66%, and incidence rose by 62%. In 2021, 15- to 39-year-olds accounted for nearly 14% of new gout cases globally, the study found.

Men from 35 to 39 years old and people in high-income regions had the highest burden, but high-income North America topped the list for highest rates.

‘SKINNY FAT’ WARNING ISSUED AS STUDY FINDS HIDDEN OBESITY BEHIND NORMAL BMI

Men were also found to have lived more years with gout due to high BMI, while women tended to have the condition as a link to kidney dysfunction, the study noted.

The total number of cases is expected to increase globally due to population growth, but the study projected that rates per population would decrease.

The researchers noted that data quality, especially in low-income settings, could have posed a limitation to the broad GBD data.

What is gout?

Gout is a common form of arthritis involving sudden and severe attacks of pain, swelling, redness and tenderness in the joints, according to Mayo Clinic. It most often occurs in the big toe.

The condition occurs when urate crystals accumulate in the joint. These form when there are high levels of uric acid in the blood, which the body produces when it breaks down a natural substance called purines.

A gout flare-up can happen at any time, often at night, causing the affected joint to feel hot, swollen, tender and sensitive to the touch.

Purines can also be found in certain foods, like red meat or organ meats like liver and some seafood, including anchovies, sardines, mussels, scallops, trout and tuna, according to the Mayo Clinic. Alcoholic drinks, especially beer, and drinks sweetened with fruit sugar can also lead to higher uric acid levels.

Uric acid will typically dissolve in the blood and pass through the kidneys into urine, but when the body produces too much or too little uric acid, it can cause a build-up of urate crystals. These are described by the Mayo Clinic as sharp and needle-like, causing pain, inflammation and swelling in the joint or surrounding tissue.

Risk factors for gout include a diet rich in high-purine foods and being overweight, which causes the body to produce more uric acid and the kidneys to have trouble eliminating it.

Experts urge patients to seek medical attention for gout flare-ups. (iStock)

Certain conditions like untreated high blood pressure, diabetes, obesity, metabolic syndrome and heart and kidney diseases can increase the risk of gout, as well as certain medications.

A family history of gout can also increase risk. Men are more likely to develop the condition, as women tend to have lower uric acid levels, although symptoms generally develop after menopause.

The Mayo Clinic advises patients to seek immediate medical care if a fever occurs or if a joint becomes hot and inflamed, which is a sign of infection. Certain anti-inflammatory medications can help treat gout flares and complications.

New study questions whether annual mammograms are necessary for most women

New study questions whether annual mammograms are necessary for most women

NEWYou can now listen to Fox News articles!

A new study suggests that annual mammograms may not be the only effective approach for preventing breast cancer.

The research, published in the Journal of the American Medical Association (JAMA), tested a risk-based breast cancer screening approach against standard annual mammography.

The WISDOM randomized clinical trial, led by study authors from universities and healthcare systems across the U.S., considered more than 28,000 women aged 40 to 74 years old, splitting them into a risk-based screening group and an annual mammography group.

ERIN ANDREWS HAD ‘NO SYMPTOMS’ BEFORE CANCER DIAGNOSIS, PUSHES FOR EARLY SCREENINGS

Researchers calculated each woman’s individual risk based on genetics (sequencing of nine breast cancer genes) and other health factors.

Those who were at the highest risk were advised to alternate between a mammogram and an MRI scan every six months. Patients with elevated risk were told to get an annual mammography and counseling.

Average-risk women were guided to get mammograms every two years, while low-risk individuals were advised to have no screening until they became higher risk or reached age 50.

The researchers found that risk-based screening did not lead to more advanced cancer diagnoses (stage 2B or higher) compared with annual screening, indicating that it is just as safe as traditional methods. The risk-based approach, however, did not reduce the number of biopsies overall, as researchers had hoped.

Among the risk-based group of women, those with higher risk had more screening, biopsies and detected cancers. Women at lower risk had fewer procedures.

“[The] findings suggest that risk-based breast cancer screening is a safe alternative to annual screening for women aged 40 to 74 years,” the researchers noted in the research summary. “Screening intensity matched individual risk, potentially reducing unnecessary imaging.”

Fox News medical contributor Dr. Nicole Saphier, associate professor of radiology at Memorial Sloan Kettering Cancer Center in New Jersey, commented that while these findings are important, the study “completely sidelines” what screenings are designed to do — detect cancer early.

“If you don’t measure stage 0, stage 1 or stage 2A cancers, you can’t tell whether personalized screening delays diagnosis in a way that matters for survival and treatment intensity,” Saphier, who was not involved in the study, told Fox News Digital in an interview.

More than 60% of breast cancers in the U.S. are diagnosed at stage 1 or 2A, where cure rates exceed 90%, the doctor noted.

The trial doesn’t “fully evaluate” whether risk-based screening changes detection at the earliest and most treatable stages, where screening “delivers its greatest benefit,” according to Saphier.

“Mammography is not without risk — radiation exposure, false positives, anxiety and potential over-diagnosis are real and should be acknowledged,” she said. “But it remains the most effective, evidence-based tool for detecting breast cancer early, when treatment is most successful.”

The expert added that labeling women under 50 as “low risk” is “outdated,” as breast cancer diagnoses are on the rise in younger females.

“Until long-term mortality data support alternative approaches, annual screening beginning at 40 for average risk women should continue,” Saphier added. “Women should be assessed for breast cancer risk by 25 years old to determine if screening should begin earlier.”
