[Comparative study of ureteral anastomosis with or without double-J catheterization in renal transplantation].

OBJECTIVE

To analyze the impact of the use of the routine double-J stent in the incidence of urological complications, like fistula, stenosis, ureteral obstruction and urinary tract infection.

METHODS

A retrospective study was conducted on two groups of patients: 28 without double-J stent and 28 with it. We reviewed urological complications: stenosis, fistula and obstruction. We paid special attention to urinary tract infection and other inherents complications to the use of double-J stents.

RESULTS

A patient from the double-J stended group (3.6%) developed a urinary fistula and there were no obstructions. 13 patients (46.6%) had a positive urinary culture in the first month post RT. Two urinary fistulas and 4 obstructions were developed in the non-stended group. Six major complications of the urinary tract. 14 patients (50%) had a positive urinary culture in the first month post RT.

CONCLUSIONS

The use of double-J stent across uterovesical anastomosis decreases the post-RT ureteral complications. Stent placement does not increase the risk of urinary tract infection in the early post-RT.
