title: Clinical results of tubeless cutaneous ureterostomy by Toyoda's method.
abstract: Tubeless cutaneous ureterostomy by Toyoda's method was conducted in 67 ureters from 43 patients during the last 9 years. Subjects included 30 males and 13 females, with an average age of 61.4 years. Most of them were afflicted with malignant tumors in the bladder, rectum, prostate, or uterus. For bilateral ureterostomy, the double-barrel method was performed in which the stoma was made at the same site in both the right and left ureters. Among 60 ureters in which pre- and postoperative changes in the renal pelvis could be traced by IVP, satisfactory results were obtained in 16 of 20 ureters treated by unilateral surgery. Of the 40 ureters treated by the double-barrel method, moderate or severe pyeloectasis was observed in 3 of the 20 ureters on the side of the stoma, while moderate pyeloectasis was seen in 3 of 20 ureters of the side opposite the stoma, and severe pyeloectasis or loss of renal function was noted in 5. Thus, renal function on the side opposite the stoma was frequently influenced by the procedure. A patient who died of disseminated intravascular coagulation syndrome soon after the operation was excluded from analysis. Tubeless cutaneous ureterostomy could be conducted in 39 of 42 patients (92.8%), excluding one whose stoma and its periphery were covered with severe inflammatory granulation and 2 with ureteral constriction.
