“…Hydronephrosis was observed in seven dogs (dog 9, 12, 14, 15, 17, 18, 19), whereas pyonephrosis was present in four dogs (dog 1, 2, 8, 20). In 15 dogs, pathologic changes in the kidney were not observed (dog 3,5,6,7,[9][10][11][12][13][14][15][16][17][18][19]. The bladder was of normal structure in fifteen dogs, four dogs had numerous inflammatory infiltrates in the bladder and in one dog, purulent inflammation was present.…”

“…Also, attempts to use alloplastic and heteroplastic prostheses made of glass, noble metals, PVC, polyethylene, silicone, teflon, dacron, and collagen coating were equally disappointing [5,[7][8][9][10][11][12][13][14][15]. A bird feather was also utilized for ureteral reconstruction [16].…”

“…Na prática urológica deparamo-nos não raramente com perdas ureterais sérias. Para evitar a nefrectomia tem-se tentado nos últimos 90 anos o reparo ou a substituição do uterer por próteses, tecidos biológicos tubulares ou não e autotransplante 1,2,3,4 .…”

RESUMOObjetivo -Pesquisar a viabilidade da alça ileal invertida como substituto ureteral. Métodos -Quarenta cães foram divididos em 5 grandes grupos de 8 animais, cada um subdividido em 2 subgrupos de acordo com a data do sacrifício (I -sacrifício em 12-15 dias de pósoperatório, e II -60 dias de pós-operatório). Nos grupos A e B fez-se a substituição ureteral parcial com selo de íleo invertido, após abertura lateral do ureter direito com 2 (Grupo A) ou 4 cm (Grupo B) de extensão. Nos demais grupos fez-se a substituição do segmento completo do ureter usando-se um tubo de íleo invertido de comprimento equivalente ao segmento do ureter ressecado com 2cm (Grupo C) e 6cm (Grupos D e E) de extensão. A mucosa ileal foi removida por raspagem ou diérese. A permeabilidade ureteral foi testada por urografia excretora e por exploração anatômica com cateter após o sacrifício. As peças foram estudas histologicamente após preparação e coloração com hematoxilina-eosina. Resultados -O número de animais com urografia normal após o seguimento foi: A-2, B-2, C-3, D-2 e E-2. A histologia revelou que a serosa ileal se reveste com urotélio, não como decorrência de metaplasia, mas do crescimento a partir da borda da mucosa ureteral. Conclusão -Conclui-se que o íleo invertido não é um bom substituto ureteral. Disponível em URL: http://www.scielo.br/acb Descritores -Substituto ureteral, tubo ileal seromuscular, lesão de ureter. ABSTRACTObjective -To investigate the outcome of ureter replacement with inverted seromuscular tube in dogs. Methods -40 adult mongrel dogs were divided in 5 groups of 8 animals. Each group was divided in 2 subgroups: 1 -sacrifice on 12-15 postoperative days, and 2 -sacrifice on the 60 th postoperative day). In group A ureter longitudinal incision 2cm long was sewed with an inverted ileal seromuscular patch 2cm long. In group B ureter incision and patch size were 4cm long. In the remaining groups a ureter segment was replaced by an inverted ileal seromuscular tube 2cm long (group C) or 6cm long (groups D and E). In all groups, except E, ileal mucosa was removed by a grasping maneuver with a scalpel. In group E the ileal mucosa was trimmed away by blunt dissection with a scissors. The ureter permeability was tested by an intravenous urogram, and after sacrifice by anatomic exploration with a catheter. All ureter segment removed through the necropsy were analyzed by histology after hematoxilin-eosin coloration. Results -The number of animals with normal urogram after the followup was: A -2, B -2, C -3, D -2 and E -2. Histology revealed that ileal serosa was covered by ureteral mucosa grown from the ureter buds. Conclusion -The inverted ileal seromuscular tube or patch does not work well for ureter replacement.
