| [ Summary ] | In terminal oncogenic terminal patients, cancer cells obstruct urinary passage and cause post renal failure by invasion of the retroperitoneal space and lymphatic metastasis. Obstruction of one side of the urinary tract is not critical. However, obstruction of both sides of upper urinary tract and the lower tract constitute a major oncogenic emergency. Moreover, when a long remaining life time is possible in terminal oncogenic patients it is important to maintain their quality of life by selecting appropriate methods for drainage of obstructed urine. For obstructions of the upper urinary tract either ureteral stents or percutaneous nephrostomy are selected. For those of the lower urinary tract, either urethral stents were used or percutaneous cystostomies were performed. Doctors who are not urologists and their staffs should know the mechanisms for alleviating urinary obstructions, including proper timing and management of stents, to produce proper catheter drainage. | |
