[Obstructive renal failure in patients with terminal malignant tumors--unilateral relief of ureteral obstruction and recovery of renal function on the opposite side].
In obstructive renal failure in patients with terminal malignant tumors, we relieved the obstruction on only one side. As a result, it was found that the renal function of the other side also recovered (in five out of 19 patients 26.3%). Therefore, obstructive renal failure in these patients was caused not only by direct obstruction by the tumor, but also by renorenal reflex, humoral factors such as uremic toxius and edema of tissues around the ureter. It would be correct to assume that a reversible mechanism, such as ureteral stent insertion, percutaneous nephrostomy, etc. Should first be selected, rather than permanent urinary diversion.
