Kulkarni Technique

Dr. Sanjay Kulkarni trained in England during 1982-86, where he performed penile invagination for urethrectomy during radical cystectomy for bladder cancer. After returning to India, he adapted the principle of penile invagination for the management of panurethral strictures. His technique employed a single perineal incision, penile invagination, one-side urethral dissection, dorsal urethrotomy, dorsal meatal incision, and placement of two buccal mucosa onlay grafts, all accomplished in a single stage. The key advantage was complete access to the entire urethra through a single perineal approach. In his early experience, he fully mobilized the urethra from the corpora, publishing these results in 1998 and presenting them at the AUA. By 2009, he refined the operation to a one-side dissection for the bulbar urethra, which evolved into the widely adopted Panurethral Kulkarni Technique, later published in the Journal of Urology in 2012.

The Asopa technique

Born in July 1932, Dr. Hari Shankar Asopa was well known not only in India but all over the world for his expertise in reconstructive surgery, especially in the field of hypospadias and stricture urethra.

The Asopa technique Also called dorsal inlay urethroplasty, is a surgical method for repairing urethral strictures using a buccal mucosal graft, named after Dr. Hari Shankar Asopa; it involves creating a dorsal incision, inlaying the graft, and preserving the urethral plate's blood supply, leading to shorter operative times, less blood loss, and good outcomes for anterior urethral strictures and was published in Urology, 2001.
