In total, 77 cases were included in the study, and the median follow-up period was 24 (5–57 IQR) months. The median age of the patients at the time of initial AUS implantation was 72 years (67.3–76.0 IQR), and the number of preoperative pads was 6.3 ± 3.0. The median operation time was 124 (105–141 IQR) min, and the size of the urethral cuff used was 4.0 cm in 27 cases, 4.5 cm in 40 cases, 5.0 cm in 5 cases, and 5.5 cm in 2 cases. The causes of stress urinary incontinence were open radical prostatectomy in 44 patients (57.1%), robot-assisted radical prostatectomy in 29 patients (37.6%), transurethral resection of the prostate in one patient, radiotherapy for prostate cancer in one patient, spina bifida in one patient, and spinal cord injury in one patient. The mean number of pads/day after surgery was 0.5 ± 0.6 at 1 year, 0.7 ± 1.0 at 2 years, 0.9 ± 1.2 at 3 years, 0.9 ± 1.4 at 4 years, 0.8 ± 1.6 at 5 years, 0.3 ± 0.5 at 6 years, 0.4 ± 0.5 at 7 years, 0.4 ± 0.5 at 8 years, and 0.3 ± 0.6 at 9 years (Figure 1A). The continence rates, defined as maintaining continence with one pad per day or less, were 94.4% at 1 year, 85.7% at 2 years, 76.3% at 3 years, 80.1% at 4 years, 85.7% at 5 years, and 100% at 6–10 years (Figure 1B). The modification-free rates of the AUS equipment were 88.0% at 1 year, 84.3% at 2 years, 76.8% at 3 years, 71.1% at 4 years, 58.2% at 5 years, 58.2% at 6 years, and 45.3% at 7–10 years (Figure 1C). After AUS implantation, the device was removed in seven cases (9.1%), reimplanted in one case (5.2%), and replaced in 11 cases (14.3%). The position of the control pump was adjusted in three cases (3.9 %). The causes of AUS removal were infection in four patients, urethral injury in two, and self-movement malfunction in one. There were six cases of urethral injury, three of which were found at the time of initial implantation, and three of these were found postoperatively. In the 11 patients who underwent AUS replacement, the median number of days from initial implantation to replacement was 1127 (1001–1603.5 IQR). The urethral size at the time of initial implantation and at the time of replacement was 4 cm (4–4 IQR) and 3.5 cm (3.5–3.5 IQR), respectively, and it was smaller at the time of replacement in all cases. In addition, the analysis of the factors affecting AUS replacement surgery revealed significant differences in both univariate and multivariate factors of urethral stricture and detrusor overactivity (Figure 2).
