Standard perineal urethrostomy cannot address lesions within the pelvic canal, and alternative open surgical techniques carry high morbidity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case description<\/jats:title>\n                    <jats:p>A 5-year-old intact male domestic shorthair cat with concurrent hypertrophic cardiomyopathy and polycystic kidney disease presented with a 7-day history of stranguria. Diagnostic imaging revealed a focal 1-mm stricture in the post-prostatic urethra.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Procedure<\/jats:title>\n                    <jats:p>Under fluoroscopic guidance, retrograde internal urethrotomy was performed using a 1.3\u202f\u00d7\u202f130\u202fmm urethral microlancet via a dorsal approach. A self-expanding laser-cut nitinol stent (5.0\u202fmm\u202f\u00d7\u202f50\u202fmm) was deployed across the stricture. A double-lumen balloon catheter was placed through the stent for 14\u202fdays to promote mucosal integration and prevent migration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The procedure was completed in 30\u202fmin with no complications. Urethral patency was immediately restored. Follow-up cystoscopy at 7 and 14\u202fdays demonstrated progressive epithelial ingrowth and near-complete encapsulation of the stent without restenosis. The cat regained normal urination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This report describes the first successful use of microlancet internal urethrotomy combined with nitinol stenting for an intrapelvic urethral stricture in a cat.
