Laparoscopic-assisted prepubic urethrostomy: experimental model in rabbit
The purpose of this study was to develop a laparoscopic-assisted prepubic urethorstomy (PPU) technique using rabbits as an experimental model. Six male New Zealand rabbits (Oryctolagus cuniculus) over six months old and weighing between 3 and 4kg (3.5kg ± 0.4) were used in this study. The animals un...

Zusammenfassung: | The purpose of this study was to develop a laparoscopic-assisted prepubic urethorstomy (PPU) technique using rabbits as an experimental model. Six male New Zealand rabbits (Oryctolagus cuniculus) over six months old and weighing between 3 and 4kg (3.5kg ± 0.4) were used in this study. The animals underwent laparoscopic dissection of the pelvic urethra, which was then exposed for the laparoscopic-assisted urethrostomy procedure. The proposed model for training of laparoscopic-assisted PPU in rabbits was considered effective and feasible. It proved to be a simple technique even for surgeons under basic endosurgery skills training, with possibilities of employing the technique for the treatment of cats with loss of function of the distal urethra.
RESUMO: Este estudo objetivou o desenvolvimento de uma técnica de uretrostomia pré-púbica (UPP) vídeo-assistida, utilizando coelhos como modelo experimental. Foram utilizados seis coelhos Nova Zelândia (Oryctolagus cuniculus), machos, com peso médio de 3.5kg (± 0.4), com idade acima de seis meses. Os animais foram submetidos à dissecação laparoscópica da uretra pélvica e posterior exposição desta para a realização de uretrostomia vídeo-assistida. O modelo proposto para treinamento de UPP vídeo-assistida em coelho foi considerado eficaz e factível, mostrando-se uma técnica exequível mesmo por videocirurgiões iniciantes, havendo possibilidade de seu emprego no tratamento de gatos com perda na função da uretra distal. |
