Optimization of uretero-intestinal anastomosis in urinary diversion: an experimental study in dogs
- 36 Downloads
Experimental evaluation of uretero-ileal reim-plantation was carried out in 10 adult mongrel dogs. One half of the ureters (10) were implanted into ileal reservoirs using the classic Le Duc technique. In the other half, the implanted ureters were covered by ileal mucous membrane. Following the classic Le Duc technique, 40% of the reimplanted ureters showed evidence of either reflux and/or stenosis resulting from shortening and fibrosis of the tunnel. The remaining 60% were perfect due to spontaneous nipple formation at the implantation sites rather than to creeping of the intestinal mucosa. In contrast, none of the ureters examined was either refluxing or stenotic. This study outlines the critical importance of covering the implanted ureters with mucosa to avoid the ureteric adventitia being exposed to the irritative effects of urine with subsequent scarring.
