This video demonstrates a diagnostic hystero-laparoscopy performed for infertility, followed by hysteroscopic lateral metroplasty to correct a T-shaped uterine cavity. The procedure begins with management of mild cervical stenosis using visual dilatation with hysteroscopic scissors before evaluating the uterine cavity. After confirming bilateral tubal patency during laparoscopy, the surgeon performs a cold-scissor metroplasty to widen the uterine cavity and improve visualization of both tubal ostia. Throughout the surgery, practical tips are shared on instrument handling, preventing bleeding, and safely performing fertility-enhancing hysteroscopic surgery. This is an excellent educational video for surgeons interested in advanced hysteroscopic management of infertility.
