MP67-04 CATHETERS IN URETHROPLASTY: A PROSPECTIVE RANDOMIZED ANALYSIS BETWEEN LATEX AND SILICONE

Abstract

INTRODUCTION AND OBJECTIVES: Voiding catheters use is needed in a variety of urethral surgery, including hypospadias repair and urethroplasty. In order to prevent the main complications related to this procedure, short term use (less than two weeks) is recommended. Urinary retention, allergy, hematuria and urinary tract infection are the main long term related complication. Silicone catheters are compared with latex in a few trials. Our objective is to evaluate the success rate in urethroplasty comparing the silicone and latex voiding catheters. METHOD(S): A total 132 patients were prospective evaluated after randomized use of silicone or latex voiding catheters. Success rate was considered absence of infectious complications and additional surgery in a 6-month interval after urethral procedure, mainly urethroplasty. RESULT(S): Median baseline age was 54 years old and mean surgical time was 148,3 min. UTI or surgical site infection were related in 33%. From the 132 cases, 26 (19.7%) required a new procedure in less 6-month interval with an overall success rate of 80.3%. Infection, urinary retention and early de novo stricture were failure causes 33%, 7% and 60% respectively. Most patients (56%) performed a buccal mucosa graft and were included in 12 of 15 cases in failure group. The latex and silicone group had a success rate of 74 and 84.1% respectively. A 0.022 p value observed a better success rate in silicone group after Fisher's exact test. CONCLUSION(S): Use of silicone catheters has shown a better success rate in this prospective randomized study in spite of the literature similarity with the latex catheters. Short term use, absence of UTI and type of procedure might be possible factors related to better surgical results.
