The 62-year-old underwent a 30-minute procedure at Furness General Hospital in Barrow, Cumbria, to remove fluid from his swollen scrotum, but two days later was rushed back to hospital for emergency surgery.
He then woke to find his right testicle was missing – which he claims he was not told would happen before going back into theatre.
Following the first operation in April, he woke up to find a vacuum drain had been inserted underneath the skin and allegedly was not checked for 24 hours.
Just two days later, the dad-of-two, from Barrow, was in excruciating pain and asked to see a doctor before being rushed back into theatre by a different surgeon.
Although patients can usually go home on the same day as a hydrocele repair op, the man had to stay in the hospital for 12 days.
The patient has now obtained copies of the operation reports, which reveal that less than 48 hours after the first op a surgeon found the testicle was “black and unlikely to recover”.
They also showed the surgeon consulted another colleague who told him to “excise the dead testicle”, and a photo was taken of the gangrenous testicle but this image was not in the patient’s records.
The man said he was in no doubt that the first operation was “botched” and it cut off the blood supply to his testicle.
He has now instructed medical negligence expert lawyer Michelle Armstrong and will attempt to sue University Hospitals of Morecambe Bay NHS Foundation Trust – which is responsible for the hospital.
The man has been left with a painful lump where his testicle was and is taking morphine as a consequence of the surgery.
Having his testicle removed has also had a huge impact on the patient’s life and self-confidence.
He says he won’t allow his wife to see him undressed and he suffers night sweats which may be caused by low testosterone levels.
The man went to see his GP earlier this year with a painful swelling on his right testicle.
After being referred to hospital, he was diagnosed with a hydrocele, a swelling that occurs when fluid collects in the thin sheath around a testicle.
The patient has also lodged a formal complaint to the University Hospitals of Morecambe Bay NHS Foundation Trust.
In July, the complaint was upgraded to a serious clinical incident and hospital bosses have launched an investigation which is due to be completed by the end of October.
UHMBT director Shahedal Bari said: “We have confirmed that due to the thoroughness of the investigation that is taking place, it is still ongoing.
“We will keep the patient informed as to the progress of the investigation, and once completed we will share the report with him.”
