Abstract

Urinary disorders are an important finding in ileocystoplasty, especially uroliths and crystalluria, and partly related to the type of suture material involved in this procedure. The aim of this study was to determine whether there are differences in the formation of uroliths and urinary crystalloid after ileocystoplasty in dogs, performed by suturing with nonabsorbable titanium staples and suture with polyglactin 910, noting their impact on renal function and urinary changes in the constitution difference in surgical time. Twelve healthy dogs were used and divided into two groups. In each animal was selected a segment of terminal ileum for bladder augmentation. In group A the suture of the detubelized ileal segment to the bladder was made with polyglactin 910 and in group B and the suture was made with titanium clips. We observed the presence of struvite crystals in 11 animals and the formation of large amounts of mucus in urine in all of them. In conclusion, no significant differences between groups in the formation of urinary crystals and uroliths after surgery, group A showed longer duration of surgery and no evidence of change in renal function in both groups. KEYWORDS: Cystectomy; mechanical suture; sutures; urinary calculi.

Highlights

Deficiencies in bladder storage capacity have considerable clinical relevance because they significantly affect life quality and may evolve to renal failure, posing a serious health threat (BRANDT et al, 2004).The bladder is exposed to a variety of injuries, even during fetal development
Bladder repair surgeries in dogs are recommended in cases of severe traumas, neoplasms and recurring interstitial cystitis (GREENWELL et al, 2001; PEREIRA et al, 2002; KOUSHYAR et al, 2007)
None of the animals died during surgery or postoperative care and none revealed clinical signs of infections, digestive alterations such as vomit, diarrhea, constipation or obstipation, suture dehiscence or intestine/bladder fistulas

Summary

Introduction

Deficiencies in bladder storage capacity have considerable clinical relevance because they significantly affect life quality and may evolve to renal failure, posing a serious health threat (BRANDT et al, 2004). The bladder is exposed to a variety of injuries, even during fetal development. In addition to congenital abnormalities, other disorders such as cancer, trauma, infection, inflammation and iatrogenic injuries eventually require bladder replacement or repair (SHOKEIR, 2002). The most frequent causes for performing bladder reconstruction are neoplasms of the lower urinary tract – mainly carcinomas – especially in humans and dogs, vesical atony, interstitial cystitis, radiotherapy, chemotherapy, multiple bladder surgeries and some congenital bladder anomalies that cause incontinence. Bladder repair surgeries in dogs are recommended in cases of severe traumas, neoplasms and recurring interstitial cystitis (GREENWELL et al, 2001; PEREIRA et al, 2002; KOUSHYAR et al, 2007). Repair procedures seek to establish a lowpressure reservoir with capacity for continence, spontaneous micturition and minimum post-micturition residue (CRANDIS et al, 1998)
