Urinary disorders are an important discovery in the ileocystoplasties, especially uroliths and bladder crystals, and are partially related to the kind of material used the in suture itself. The purpose of this study is to verify if there are differences regarding the formation of uroliths or bladder crystals after dogs ileocystoplasties practices involving sutures using unabsorbed titanium staples and sutures with polyglatine 910, observing the impact of the procedure in the renal function, modifications in the urinary constituents and differences in the surgery time duration between the groups. For that, two experimental groups of animals, each one with six, have been considered. In one group it has been used a polyglactin 910 suture thread (group A) and in the other, a titanium stapler (group B). In each animal of both groups there was selected a terminal ileac segment with approximately 5 cm for bladder augmentation. In group A, a suture of the detubularized ileum segment in bladder was executed using a polyglactin 910. In group B, the bladder augmentation with the selected ileac segment was done by linear cutter stapler using titanium staples. It was observed the presence of struvite crystals in both groups, in 11 animals of the experiment. In group A the operation duration was longer if compared to group B . It was also observed the formation of urinary mucus in great quantity in all animals in the post-operation first days. It was confirmed the formation of calculi in two animals, one in each experimental group, but in the group A animal the calculi was free from lumen and in the group B animal the stone was adhered to the stapling zone, attached to a staple that got exposed to direct contact with the urine. In the parameters verified in the urinalysis, urea and seric creatinine there was no sign of renal alteration and in the verification of blood count, no alterations were noticed or considered significant. It was possible to conclude that no significant differences were observed between the groups as for the formation of urinary stones and crystals in ileocystoplasties after 100 days. If compared to group B , Group A presented a longer operation and there were not evidences of alteration in the renal function in any phase of the experiment in both groups
