Reflux and stricture formation following translation ureter sigmoidostomy with submucous tunneling

ABSTRACT

20 renal units the ureters of which were transplanted into the sigmoid colon through a transcolonic approach using submucous tunnelling were fully evaluated 6 months postoperatively. Assessment of the results showed a low incidence of reflux due to the ample submucous tunnelling and a low incidence of stricture formation due to mucosa anastomosis and due to the avoidance of suturing in the formation of the submucous tunnel since sutures carry the potential risk of kinking and/or stenosing the ureter
