“…In the majority of dogs which underwent the ureteral substitution-reconstruction with the tube-graft of the tunica albuginea, unfavorable histologic changes were present -dogs: 1,2,8,9,11,12,14,15,[17][18][19][20] (Table 3).…”

“…Injuries or strictures in the upper and lower segments of the ureter may be, with good results, repaired by pyeloplasty or cystoplasty. Also, the loss of uretral tissue due to a stricture or trauma, if it is not longer than 2 cm, can easily be repaired by direct end-to-end anastomosis [1][2][3][4][5]. Management of multiple strictures or injuries in the mid-ureter is associated with many problems, especially if a longer segment is affected.…”

Introduction Complex ureteral obstruction is a pathology that has always been a challenge for the urologist, especially in patients with high surgical risk or with a short life expectancy. Material and methods Between 2002 and 2017, 13 extra-anatomical bypasses were placed. A descriptive retrospective study was carried out. An analysis of the permeability time of the prosthesis was performed using Kaplan-Meyer curves. Demographic and etiological characteristics as well as early and late complications were analysed. Results Etiologies were benign in 39% (including 3 transplant recipients) and malignant in 69%. Permeability rates were 90.9% at each of 12, 24 and 48 months, respectively, and 75.8% at 60 months. There were no deaths in the early postoperative period, nor intraoperative complications. The most frequent complications were infections. Three of them were associated with bypass extrusion, which needed to be removed. A total of 5 prosthesis had to be removed. 40% of the patients did not present complications. Conclusions The extra-anatomical ureteral bypass is an alternative to permanent nephrostomy in the treatment of complex ureteral strictures. Their patency rates after long-term follow-up vary from 90% to 75% at 48 and 60 months, respectively. Their complication rates can be considered acceptable in the patients’ clinical contexts.

The Use of Bowel Interposed Between Proximal and Distal Ureter in Urinary Tract Reconstruction

et al. 1985

The replacement of lost ureter with bowel interposition is a feasible alternative in the reconstruction of the urinary tract. When adequate ureteral length is not present, interposition of a portion of small bowel between the proximal and distal ureteral segments is an option that minimizes the amount of bowel in the urinary tract. This, in turn, reduces mucus production and electrolyte absorption in the reconstructed urinary tract, and allows for more bowel to remain as part of the functioning gastrointestinal tract. This procedure allows use of the antirefluxing function of the normal ureterovesical junction when present. We have used successfully interposition of the small bowel between the proximal and distal ureteral segments for undiversion in 5 children. Generally, we strive to join urothelium to urothelium without the use of bowel in urinary tract reconstruction but when this is not feasible, bowel interposition has been a useful option.
