Factors effecting the outcomes of artificial urinary sphincter placement: a single-center study

Abstract

Objectives: To evaluate the patients who underwent artificial urinary sphincter (AUS) placement and reportoutcomes of the procedure.Methods: From March 2008 to February 2017, the data of patients who have undergone AUS placement wereevaluated retrospectively. Age, body-mass index (BMI), comorbidities, education level, previous radiotherapy(RT) history of the patients were recorded. Cognitive status was examined using the Mini Mental StatusExamination test (MMSE). International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF)was completed pre- and post-operatively. Quality of life and satisfaction of patients were evaluated usingPatient Global Impression of Improvement (PGI-I) scale. To analyze factors effecting success and revisionrates, patients were grouped according to age, BMI, comorbidities, smoking habbit, previous RT history andetiology of incontinence. Treatment success was defined as requirement of ≤ 1/day.Results: A total of 61 patients were included in the study and each were cognitive intact (MMSE > 25). ICIQSF significantly improved in postoperative period (p 25 kg/m2 was the only significant factor associated with revision requirement andthere was no significant factor associated with success status.Conclusion: AUS placement is a safe and effective method in the treatment of post-prostatectomy incontinence(PPI). Success and revision rates are similar regardless the etiology of PPI. Cognitive functions of patientsmay be crucial in the postoperative satisfaction status.
