I find the reconstructive aspect of urologic surgery the most exciting and challenging from a strategic and surgical perspective. Reconstructive urology provides an opportunity to help improve and to restore function as well as aesthetics for the patient who has endured injury, cancer, previous surgical complications, or congenital conditions. The uniqueness of each case poses a tactical and a surgical challenge, requiring a highly individualized and carefully planned and executed surgical approach to address the problem and underlying anatomical and medical cause. Within the emerging subspecialty of reconstructive urology, I focus on complex urethral stricture disease utilizing anastomotic and substitution urethroplasty; management of upper urinary tract obstruction; urinary fistula repair; prosthetic urology including penile implants for erectile dysfunction, as well as artificial urinary sphincters and minimally invasive slings for male stress urinary incontinence; penile reconstruction for Peyronie’s disease; and a comprehensive approach to male sexual health and male wellness.
