Recently Hangzhou Third People’s Hospital treated a special patient Mr. Han, Mr. Han’s family is Tonglu rural, 20 years ago found a small stone inside the kidney, due to the pain is not very strong, also do not want to spend more money, did not choose to deal with kidney stones, eat a little painkillers even if the past. For 20 years, although Mr. Han also knows that he has small stones in the kidney, and occasionally back pain, but always did not take it seriously, but the stomach slowly became larger, like a beer belly. In recent months, the waist up really can not stand, go to the local hospital a check, which can be frightened, the ultrasound shows that the whole stomach is full of water, the left kidney can not be found, rush to scan a CT, CT results, the left kidney is not no more, but became a ball, the kidney is full of water, the ureter has a small 1 cm stone. But this small stone has been blocking the kidney for years, and the more urine accumulates, the more the kidney blows into a ball. The local hospital had no choice but to transfer the kidney to our hospital, and after the relevant examination, the left kidney was basically no longer functional. After a serious discussion, our urology team chose to use laparoscopy to do the operation. Three small holes of 1 cm were used to take out this 30 cm ball of skin. The surgery was completed in only 2 hours because our hospital’s team of specialists has extensive experience in laparoscopy. More than 5000ml of fluid was drained from inside the kidney during the operation. After the surgery, Mr. Han recovered well and was discharged from the hospital in 5 days, but his mouth kept saying: “I should have taken out this small stone when I knew it was going to take out my waist”. I would like to remind everyone that a small stone can cause serious consequences, early detection, early diagnosis, early treatment to achieve the best results. Do not delay to see the doctor, the disease is not to leave, only to drag more and more serious. The following is the CT photo of Mr. Han’s left kidney occupies half of the abdomen. After pumping the fluid kidney, like a deflated ball of skin red this bucket is the urine drained from the kidney, 5000 ml.
