Purpose: While pump manipulation is rarely problematic in male patients with artificial urinary sphincters (AUSs), the situation may differ in female patients due to anatomical or cultural factors. This study aimed to evaluate the prevalence of difficulties in pump manipulation among female AUS patients, identify associated risk factors, and explore management strategies for this challenging issue.
Methods: Data were collected from all female patients who underwent a robotic AUS implantation at a single academic center between 2014 and 2022. The primary endpoint was temporary difficulties, defined by at least one other short hospitalization to learn pump manipulation.
Results: Out of the 88 female AUS patients included in the study, 20 experienced initial difficulties manipulating the pump, accounting for 22.7% of the group. Temporary difficulties were reported by 16 patients (18.2%), while 4 patients (4.5%) had their devices permanently deactivated. Surgical reoperations to reposition the pump were necessary for 5 patients, representing 5.6% of the sample. The only variables significantly associated with temporary difficulties were longer operative time (183.4 minutes vs. 159.1 minutes, P=0.04) and the overall experience of the center (32 vs. 50, P=0.04). The sole variable significantly linked to serious difficulties was the overall experience of the center (11 vs. 47, P=0.004). Although the median age and body mass index were higher in the group with temporary difficulties, these differences were not statistically significant.
Conclusion: Difficulties in manipulating the pump are relatively common among female AUS patients. Most of these difficulties can be resolved through repeated patient education and careful follow-up. However, some may lead to serious complications. Raising awareness of this issue, along with ongoing patient education and meticulous follow-up, may help to minimize these consequences.
