Retrograde endopyelotomy in association with active distal ureteral dilation: a contraindication for the use of the 7F ureteral "tail" stent.
Since its introduction in 1997, the 7F "Tail" stent has been used after a variety of endourologic procedures. We describe 2 patients who underwent retrograde endopyelotomy with distal ureteral dilation; in both patients, after placement of a 7F "Tail" stent, a clinically significant urinoma developed. We believe that in the setting of extensive distal ureteral manipulation or distal active ureteral dilation to greater than 10F, placement of a "Tail" stent is contraindicated.
