An observation is presented of a patient with right renal cancer that invaded the caecum and the ascendant colon, as well as the descending duodenum. Enlarged nephrectomy was performed and right hemi-colectomy and resection of the antero-lateral wall of the duodenum. Termino-terminal ileo-transversostomy was performed and the duodenal defect was "patched" with the last ileal loop and its serosa.
A case is discussed, of extensive ureteral stenosis that could not be solved by uveal intubation, neither by two ureterocalycostomies, in which total ureteroileoplasty gave immediately good results.
Two cases are presented, of transuretheral ureterostomy combined to cutaneous ureterostomy and total cystectomy (in a patient with invading neoplasia of the urinary bladder), or with a procedure of urinary derivation (in the second patient with complex urinary tuberculosis and advanced renal failure). The results obtained were very good.
Out of a total of 475 interventions for renal lithiasis, the author has performed only 15 partial nephrectomies, as compared with 118 total nephrectomies and 342 conservatory pyelotomies and nephrotomies. The type of intervention described should be limited to cases where the polar parenchyma is jeopardised--partial tactical nephrectomy should be abandoned.
