Conservative surgery of renal cell carcinoma.
Abstract From 1967 to 1985 conservative surgery (enucleation, n = 49; partial resection, n = 7) was performed for renal tumors in 57 patients (age 31-77, mean 54.8 years). Imperative indications for conservative surgery (n = 29) were chronic renal failure, benign pathology of contralateral kidney, functional or anatomical solitary kidney, and bilateral tumors. Elective conservative surgery (n = 28) was done for small, peripherally located lesions, in cases of uncertain malignancy and in one tumor detected by chance during stone surgery. Tumors removed for imperative indications were 2-11 cm (mean 5.8 cm) in size. In the elective group, tumor size ranged from 1 to 7 cm (mean 3.3 cm). Follow-…
Local excision of urothelial cancer of the upper urinary tract.
Abstract In 9 of 93 patients (9.7%) with urothelial cancer of the upper tract (7 renal pelvis tumors, 3 ureteral tumors), conservative surgery was employed using a free peritoneal autotransplant for replacement of the renal pelvis in 5 kidneys. Absolute indications for conservative surgery were solitary kidneys/nonfunctioning contralateral kidneys in 4 patients and bilateral tumors in 1 patient. Local recurrences developed 1-3 years after operation in 4 of 6 kidneys (3 patients), 3 of which had grade-2 and grade-3 primary lesions. All patients were treated successfully by repeated local excision. In the presence of a normal contralateral kidney, local tumor excision was done electively in 4…
