OBJECTIVES: The purpose of this experimental study is to assess the additive effects of temporary JJ stent placement together with metal stents (MS) in the @entity3551 , in order to reduce @entity1373 formation. METHODS: Twenty-four @entity1707 were included, and an experimental model of obstructive @entity3551 was created. Six weeks after obstructive @entity3551 model induction, @entity1695 was confirmed using ultrasonography, ureteropyelography and endoluminal ultrasound. Afterwards, animals were randomly distributed into 2 groups. Group I underwent covered MS placement and JJ ureteral stenting for 3 weeks. Animals in Group II received the same MS without simultaneous JJ stenting. The follow-up was at 3 weeks and at 6 months. RESULTS: Incidence of @entity1373 was higher in Group I than Group II, but without statically significant differences. On the other hand, Group II showed a significantly higher degree of @entity3885 severity due to @entity1373 . The migration rate in both groups was 33.3% at the end of the study. Significant differences were shown on animals showing @entity293 ( @entity293 ) and @entity1373 against those with @entity1373 but no infection. There was a high rate of correlation between @entity293 and obstructive @entity1373 . CONCLUSIONS: Placement of JJ ureteral catheter does not inhibit @entity1373 associated with placement of metal mesh stents, although it significantly reduces its obstructive severity in long-term follow-up. @entity293 is directly related to the development and magnitude of the @entity1373 .
