About this study
Official title: Joshi's Step With Buccal Mucosal Graft Urethroplasty in Nearly Obliterated Bulbar Urethral Stricture: A Prospective Study
This study aims to evaluate the functional and surgical outcome of Joshi's step with buccal graft urethroplasty for the management of nearly obliterated bulbar urethral stricture.
Read the detailed description
Urethroplasty is a rapidly evolving art that continually improves and reinvents itself. After a century of silence, during which the anastomotic repair was the only solution for approaching the strictured urethra, the 1990s can be considered the Renaissance period for reconstructive urology.
In 2022, Joshi and Kulkarni introduced a new step to the augmented urethroplasty, particularly in patients with extremely narrow strictures where a single augmentation was insufficient. They avoid any resection of the residual native urethral plate, marking the narrowest portion. Then, the edges of the mucosa are reapproximated with interrupted suturing in a proper non-resecting approach.
