Abstract

Urethral stenosis is a common diseasein the clinical practice of urology, with a major impacton the quality of life of patients. The anastomoticurethroplasty is a technique with very precise indicationsusually membranous or bulbar urethra stenosis with alength of 3 cm or up to 7 cm when it is secondary tourethral disruptions (no stenosis) after pelvic trauma.OBJECTIVE: We review anastomotic urethroplastyperformed in our department between 2002 and 2015.METHODS: A retrospective, descriptive and inferentialanalysis on 107 patients out of 482 treated withAnastomotic urethroplasty by urethral strictures at theUrology Department of the Hospital “Virgen de la Victoria”(Malaga) from January 2002 to September 2015,establishing effectiveness and safety of the technique,as well as factors that might influence the results. Themain diagnostic method was retrograde urethrographyand voiding cystourethrography in 100% of patientsundergoing surgery, using voiding uroflowmetry forsubsequent monitoring. The definition of success was apostoperative flowmetry with Qmax>15 ml/s, and incase of lower flow, we perform a cystoscopy to verifyrecurrence of stenosis or exclude other pathology.RESULTS: The median age was 42 years, with amean follow up of 59 months. The length of stenosisvalued by retrograde urethrography and voidingcystourethrography was in 91.6% of cases of >1 cmand <2 cm. The most common etiology was idiopathicin 72.9%, followed by iatrogenic with 15.9%.Regarding the location, it was observed that the areamost often affected was the bulbar urethra with 82.2%,with the membranous urethra in second place. In 77.6%of patients anastomotic urethroplasty was the initialtreatment, followed in frequency by direct vision internalurethrotomy 9.3%.In the case of comorbidities associated with treatmentwith anastomotic urethroplasty it was observed thatonly Diabetes Mellitus had a tendency to statisticalsignificance, with p=0.092, not demonstrating suchsignificance in the case of hypertension or when thesubject presented Diabetes Mellitus together withhypertension. Finally, the intervention was successful in102 cases (95.3%), with only 5 cases (4.7%) whereit failed, 4 of them treated with a new Anastomoticurethroplasty, with resolution of the stricture.CONCLUSIONS: Anastomotic urethroplasty is thetreatment of choice for short bulbar urethral stricture, withhigh success rate and low complication rate, as well aslow recurrence of these.
