The old man, who is 84 years old, is a disembodied old cadre and lives in Shenzhen. 18 years old, he joined the Dongjiang Column and has fought countless battles, large and small, with his troops and experienced countless baptisms of fire and bullets, but has never been wounded and has never suffered from any disease. On July 23, due to the re-emergence of painless hematuria, his family rushed him to the Department of Urology of the Third Affiliated Hospital of Southern Medical University, where he was diagnosed with right renal pelvis cancer after ultrasound, intravenous pyelogram, CT and other comprehensive examinations. Laparoscopic radical treatment of right renal pelvis cancer is the only option. This disease is highly malignant and rapidly developing, and the only way to save life is to operate as soon as possible. Traditionally, right renal pelvis cancer is a complex surgery that requires the removal of the diseased kidney, ureter and the entire bladder around the ureteral opening, which is about 1 cm in diameter, in two separate procedures. Due to his advanced age and extreme frailty, the old man was not only unsuitable for traditional surgery, but minimally invasive surgery also posed great risks. We did not give up on the treatment of the old man and organized a hospital-wide consultation, and asked the cardiology and respiratory departments to conduct a comprehensive assessment of the old man’s cardiopulmonary function. After meticulous examination and discussion, it was concluded that the patient was theoretically ready for surgery. After repeated arguments, Professor Liu Cundong designed a set of minimally invasive and rapid surgery plan, and after obtaining the consent of the family, the medical and nursing staff actively carried out all-round preparation to ensure the safety of the old man during and after the operation. on July 31, Professor Liu Cundong, director of the Department of Urology, with the cooperation of the Department of Anesthesiology, performed a retroperitoneal lumpectomy for Mr. Liu’s radical right nephrectomy. Due to adequate preoperative preparation, the operation went very smoothly. On the first day after surgery, the patient’s vital signs were stable and all monitoring indicators were normal. Blood in urine without pain should be highly alert According to the introduction, advanced age is one of the main risks of surgical procedures, the whole body organ functions of the elderly are in a degenerative state, even if all preoperative examinations are normal, there are great risks during and after surgery, but as long as the surgical risks are fully evaluated and preoperative preparations are carefully done, surgical treatment can still be chosen when the physical conditions of the elderly patients permit. The typical “triad” of renal cell carcinoma is hematuria, pain and mass. Hematuria is characterized by intermittent and painless hematuria, and some patients may show hematuria that can only be detected under microscope; it is also reported that there are about 360,000 new cases of bladder cancer worldwide every year, and the incidence rate ranks 9th among malignant tumors, with men accounting for about 75% to 80%, and the average age of onset is 70. The main symptom of bladder cancer is also hematuria, which is characterized by painlessness and intermittency. If blood in urine is accompanied by pain, it is usually caused by benign diseases such as bacterial infection of urinary system and stone disease; however, if blood in urine is not accompanied by pain in middle-aged and elderly people, the occurrence of urinary tumor should be highly alerted.
