Surgical resection is the standard treatment for the management of localized penile cancer and a neo-urethral meatus is generally created on the penile stump or perineum. Neo-urethral meatus is often stenosed and requires repeated transurethral manipulations such as dilation and urethrotomy. These procedures are generally futile and are associated with poor quality of life. Here, we report a case of penile cancer that developed a neo-meatal stenosis after total penectomy, which was subsequently salvaged by perineal urethrostomy using Blandy technique. A 72-year-old male who was diagnosed with localized penile cancer, underwent total penectomy and creation of neo-meatus on the perineum. Neo-meatus stenosis had developed in the patient and he received repeated urethral dilations without any success. Finally, when the patient was unable to void, he was referred to us for the amelioration of meatal stenosis through the placement of a suprapubic catheter. Because the condition of the residual bulbar urethra was adequate and its length was enough, we planned to create a non-transecting perineal urethrostomy by Blandy technique. An inverted U-shaped perineal incision was made, and a skin flap was created. The scarred neo-meatus and spongiofibrosis at the distal bulbar urethra were completely excised. The residual bulbar urethra was exposed, and a longitudinal ventral incision of 4 cm was made. The edge of the bare urethral mucosa and tunica albuginea of the corpus spongiosum were sutured by 4-0 PDS for hemostasis. The apex of the U-shaped skin flap was brought to the proximal margin of the urethrotomy and a tension-free anastomosis was created between the skin flap and the urethral plate. Thereafter, the skin of the perineum was sutured to the open longitudinal urethrotomy. The patient started to void on the 5 day post-surgery. The subject could void without the help of any intervention and did not require any instrument, sixteen weeks after the surgery.
