”Ureteral malformation without surgery, advanced technology to benefit the people”. A few days ago, the urology department of Gaocheng People’s Hospital received such a banner. The banner was presented to a patient suffering from a rare ureteral malformation, the ureter after the vena cava, who visited several hospitals in Maoming and said that they had to operate, and came to Gaocheng People’s Hospital to successfully correct this rare malformation without surgery, for which the patient’s family was very grateful. The patient is a 16-year-old Lin from Shuidong Town, Dianbai County, Maoming City, who is less than 170 cm tall but weighs 100 kg. According to him, three years ago there was a sudden onset of severe pain in the right lumbar region, head cold sweat, and could not straighten his back. When he went to a hospital for examination, it was said that there was a 0.6 cm stone in the ureter. The family helped him to find some herbal medicine to serve, three years no more pain, the family thought the stones disappeared. In mid-August this year, Lin appeared right back pain again, went to another large hospital for examination, but the results are not stones, but a rare ureteral malformation – vena cava posterior ureter and right hydronephrosis, said only open surgery, young Lin heard to open surgery, very scared. After many inquiries, learned that the urology department of Gaozhou City People’s Hospital two years ago to carry out minimally invasive laparoscopic surgery to treat this disease, Lin was admitted to the hospital’s urology department two. In normal people, the ureter and the inferior vena cava run parallel downward, but the patient’s right ureter wrapped backward around the inferior vena cava in a circle, thus causing ureteral obstruction and hydronephrosis. The surgery required complete freeing of the malformed right ureter from the inferior vena cava, followed by cutting the ureter, repositioning it, and then anastomosing it. To complete these operations under laparoscopy, the surgical field of view is very small, and coupled with the patient’s obesity and the large amount of fat accumulation around the inferior vena cava, the surgical field of view is even smaller, and it is even more difficult to separate the inferior vena cava and ureter, which requires excellent technique and rich clinical experience of the surgeon. After thorough preparation, Director Feng Zhenhua personally performed a laparoscopic posterior vena cava ureteroplasty on the patient, which successfully corrected a rare ureteral malformation by making only three small incisions in the patient’s abdomen the size of a keyhole. The patient was able to get out of bed the day after surgery. According to Director Feng, posterior vena cava ureter is a rare congenital disease of the urinary tract, and most hospitals are still using open surgery for this disease. This advanced, minimally invasive technique was performed two years ago at Gaozhou People’s Hospital and is now well versed in it.
