Experimental substitution of a long segment of ureter by a fallopian tube was performed in dogs. Three different techniques of proximal and distal anastomosis for reconstruction of the urinary tract were used in three groups of animals. Based on this, it is believed that the fallopian tube, as a pedicle graft, could serve in female dogs as the most approximate ideal substitute for ureter because of (a) anatomic proximity to the ureter permitting blood supply to the tube, (b) the fallopian tube’s mucosa lining is not affected by urinary excretions, (c) does not allow absorption of electrocytes, (d) has a muscular wall with peristaltic activity, and (e) avoids the problems of antigenicity and/or foreign body reaction.

“…Dentre as próteses, várias substâncias sintéticas foram testadas como o polietileno 5 , o silicone 2 , o teflon 6 , e o gore-tex 7 , com resultados variáveis mas geralmente insatisfatórios devido a cristalização de sais, deiscência das anastomoses, ausência de peristaltismo ou obstrução.…”

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.

In 14 canines the ureter was substituted with a new type of ureteral gel-fabric prosthesis. The prosthesis is a tube of knitted fabric of polyester fiber case in a layer of hydrophilous glycol methacrylate gel. Anastomoses were carried out by insert'ing the prosthesis ends into the ureter lumen and by suturing the stump of the ureter to a special fixing ring on the prost,hesis. Preliminary results of short-term observat,ions (4 mont,hs) are quite promising. The prosthesis is lion-irritating and coiidiicts t,he urine satisfactorily.
