World's first bladder transplant marks ‘historic moment' as man, 41, able to pee again for first time in 7 years
SURGEONS have performed the first-ever human bladder transplant - a game-changing procedure with the potential to help thousands living with deadly organ failure.
The first person to undergo the operation is 41-year-old Oscar Larrainzar, a father of four who had previously lost most of his bladder during a tumour removal process.

The remainder of his bladder was too small to work and both his kidneys were subsequently removed due to cancer and end-stage kidney disease.
He'd been on dialysis for seven years.
The complex procedure carried out by surgeons from UCLA Health and Keck Medicine of USC involved the transplantation of both a new bladder and a new kidney, recovered from a donor, and lasted approximately eight hours long.
UCLA urologic transplant surgeon Dr Nima Nassiri and Dr Inderbir Gill, assisted by a surgical team, said the results were quickly evident.
'The kidney immediately made a large volume of urine, and the patient's kidney function improved immediately,' Nassiri said.
'There was no need for any dialysis after surgery, and the urine drained properly into the new bladder.'
'Despite the complexity of the case,' Gill said, 'everything went according to plan and the surgery was successful.
"The patient is doing well, and we are satisfied with his clinical progress to date.'
It's not known how well the transplanted bladder will function over time and how much immunosuppression will be needed to prevent rejection of the transplanted organs.
But to date, Larrainzer has been stable.
I haven't peed in SIX YEARS and never will again - I live in constant agony and it could kill me
'This surgery is a historic moment in medicine and stands to impact how we manage carefully selected patients with highly symptomatic 'terminal' bladders that are no longer functioning,' said Gill, who is also a distinguished professor and chair of urology at the Keck School of Medicine of USC.
'Transplantation is a lifesaving and life-enhancing treatment option for many conditions affecting major organs, and now the bladder can be added to the list.'
Bladder transplants haven't been carried out previously because of the complicated vascular structure of the pelvic area and the technical complexity of the procedure.
Current treatments include the replacement or augmentation of the urinary reservoir - a procedure that uses part of a patient's intestine to create a "new" bladder or a pathway for urine to exit the body.
While these surgeries can be effective, they come with many short-and long-term risks that compromise a patient's health, such as internal bleeding, bacterial infection and digestive issues.
'A bladder transplant, on the other hand,' Nassiri said, 'results in a more normal urinary reservoir and may circumvent some short- and long-term issues associated with using the intestine.'
Organ transplants currently available
Organ transplants, which replace failing or damaged organs with healthy ones from donors, are now available for a variety of organs.
They've become possible due to advancements in surgery, medicine (including immunosuppressant drugs), and a better understanding of the donor process.
Available organs include:
Kidneys: The most commonly transplanted organ, helping patients with end-stage kidney disease.
Liver: Treats various liver diseases, including cirrhosis and liver cancer.
Heart: Addresses heart failure and other heart conditions.
Lungs: Treats conditions like cystic fibrosis, pulmonary fibrosis, and other lung diseases.
Pancreas: Transplants are used to treat diabetes and some pancreatic cancers.
Intestine: Transplants are performed for patients with severe gastrointestinal disorders.

Blood test for Alzheimer's disease is highly accurate, researchers say
Researchers say a new blood test for Alzheimer's disease has been shown to be highly accurate in detecting people with early symptoms. Scientists looked for two proteins - amyloid beta 42/40 and p-tau217 - and found the test was 95% accurate in identifying patients with existing cognitive impairment linked to the condition. The US study involved 509 patients in an outpatient memory clinic in Florida and was published in the medical journal Alzheimer's and Dementia. The test, which has already been approved by the US regulator, was also 82% accurate for specificity, which means it could rule out people without dementia. Dr Gregg Day, who led the study, said the test was as good as existing, but more invasive, tests. He said the next step was to extend the test to a wider range of patients, including those with early Alzheimer's who do not have any cognitive symptoms. Scientists say the two proteins, which they have identified in blood plasma, are associated with the buildup of amyloid plaques. Amyloid protein can be found in our brains, but in Alzheimer's disease, amyloid sticks together and forms abnormal deposits, which are thought to be toxic to brain cells. Dr Richard Oakley, associate director for research and innovation at the Alzheimer's Society in the UK, said the results "suggest this test is very accurate". "Blood tests will be critical to accelerate diagnosis and give more people access to the care, support and treatments they desperately need faster than ever before," he added. In the UK, the Blood Biomarker Challenge is a multi-million-pound research programme supported by the Alzheimer's Society, Alzheimer's Research UK and the National Institute for Health and Care Research. 1:09 Its goal is to bring blood tests for dementia diagnosis to the NHS by 2029. Dr Julia Dudley, head of research at Alzheimer's Research UK, said: "We urgently need to improve how we diagnose dementia and it's great to see international research working towards this goal." She said the studies like the Blood Biomarker Challenge are a "crucial part of making diagnosis easier and faster, which will bring us closer to a cure". "The study is testing blood tests, including p-tau217, in thousands of people from sites across the UK," she added.

Starmer goes all in on NHS with PM set to hand health service £30bn spending boost at expense of other public services
Sir Keir Starmer will pump money into the NHS at the expense of other public services. The government is putting all its eggs in one basket as it lines up the Department for Health for a £30billion cash boost at next week's spending review. However, health chiefs have warned the prime minister's promise to 'turbocharge delivery' could lead to difficult compromises elsewhere in services from the police to councils. It comes after the party's unexpected victory in the Hamilton, Larkhall & Stonehouse by-election - though as the threat of Nigel Farage 's Reform UK still looms large. The Department for Health will be handed an increase of around £200billion to its budget by 2028 - a £17billion rise in real terms. Its day-to-day budget is set to increase by 2.8 per cent in real terms annually over the three-year spending review period. Sir Keir has also pledged to have 92 per cent of NHS patients treated within 18 weeks by the next election, a target that has remained unmet for a decade. Currently, under 60 per cent are seen within this time with waiting lists rising to 7.4million last month. There are even fears NHS bosses may not hit an interim goal of 65 per cent next year. Chancellor Rachel Reeves' prioritisation of health has forced cuts in other departments and prompted protestations from other cabinet members like Yvette Cooper, the home secretary and Angela Rayner, the deputy prime minister and housing secretary. Both have warned Ms Reeves the cuts will put some of the government's crime and housing targets at risk amid 'robust negotiations'. But the chancellor has maintained 'not every department will get everything they want'. Overall, the health budget, which stood at £178billion as Labour took office, will exceed £230billion by the next election. The increase means health is set to account for 41 per cent of all day-to-day departmental spending - up from 39 per cent. Ben Zaranko, of the Institute for Fiscal Studies, said Ms Reeves's cash boost was 'a serious, meaningful increase in health funding'. But Matthew Taylor, chief executive of the NHS Confederation, warned the funding increase 'is not going to enable us to achieve recovery and reform' without big changes to the way the health service treats patients. He said the government's plan to withhold the budget for infrastructure simultaneously would also make 'combining recovery and reform' impossible.

Health Secretary to unveil 'death of the doctor's letter' in digital first switch to help slash NHS postage bills
Ministers will today announce the death of the doctor's letter in a bid to slash NHS postage bills. Health Secretary Wes Streeting will unveil plans to switch to a 'digital first' system, with almost all patient communications made via the NHS app. The move, agreed as part of next week's spending review, will mean most patients will no longer receive letters about appointments, check-ups and screening dates. People unable to use the app will be able to continue receiving a postal service, but only as a 'last resort'. The Department of Health said the move would lead to the NHS sending out 50 million fewer letters a year, saving £200 million on stamps and envelopes. However, critics warned it could disadvantage millions of older people who struggle with the latest technology. Dennis Reed, director of the Silver Voices campaign group, said the move would accelerate the trend towards digital communications that risks turning some older people into 'second class citizens' and could result in vulnerable patients missing appointments. Last night Mr Streeting insisted that 'modernising' communications would 'put power in the hands of patients'. 'People are living increasingly busy lives,' he said, 'and want to access information about their health at the touch of a button, rather than wait weeks for letters that often arrive too late. 'The NHS still spends hundreds of millions of pounds on stamps, printing, and envelopes. By modernising the health service, we can free up huge amounts of funding to reinvest in the frontline.' Health sources said Royal Mail had become so unreliable in parts of the country that some letters didn't arrive until after appointment dates or else people didn't open their post in time. Mr Reed told the Mail: 'Many older people do not have smartphones and many of those that do only use them for making calls. There are still a lot of people who do not know how to use apps or who physically cannot navigate them on a tiny screen. 'If you try to force them to use an app then people will miss messages and vital appointments.' Caroline Abrahams, director of Age Concern, said technology brought 'many potential benefits', but added: 'This is a big risk because millions [of older people] do not use computers at all, or only do so for limited purposes. 'If the NHS app is to become the default, then this major change must be accompanied by many more opportunities to help people of all ages to go online if they wish to do so.'
