In the Coloplast Touch group (n\u2009=\u20091907), 214 patients (7.6%) required reoperation or replacement, with 149 cases (69.6%) due to mechanical failure. Median time to reoperation was 59.1\u00a0months. Kink-resistant tubing (KRT) malfunction was the leading cause. Most tubing fractures (77%) occurred at the connection between the KRT and strain relief boot near the scrotal pump. Other fracture sites included the cylinder junction (13.7%), reservoir junction (5%), and KRT\u2013KRT connections (2.9%). Additionally, 34% of failures involved sidewall erosion of the KRT without complete fracture.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical implications<\/jats:title>\n                    <jats:p>Identification of recurrent anatomic failure points may inform surgical technique modifications and device design improvements aimed at reducing mechanical failure rates and extending implant longevity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Strengths and limitations<\/jats:title>\n                    <jats:p>Strengths include a large single-institution cohort with long-term follow-up and uniform surgical technique.
