title: "Snodgraft" technique for the treatment of primary distal hypospadias: pushing the envelope.
abstract: OBJECTIVE
  "Snodgraft" modification has been proposed to reduce the risk of meatal/neourethral stenosis in distal hypospadias. We applied the Snodgraft technique by using inner preputial graft in primary distal hypospadias repair.
  
  
  METHODS
  A total of 102 consecutive patients undergoing the Snodgraft procedure were prospectively studied between 2006 and 2011. Mean patient age was 7.2 years. Localization of the meatus was glanular in 5 patients, coronal in 49, subcoronal in 45 and mid penile in 3. In all patients the posterior urethral plate was incised, and the graft harvested from the inner prepuce was sutured from the old meatus to the tip of the glans. A neourethra was created over a urethral catheter using 6-zero polyglactin suture. An interpositional flap was laid over the urethra as a second barrier. All patients were followed at 3 to 6-month intervals for cosmetic and functional results.
  
  
  RESULTS
  At a mean of 2.4 years of followup no patient had meatal stenosis or diverticulum at the inlay graft site. However, urethrocutaneous fistula was observed in 10 patients (9.8%). A slit-like appearance of neomeatus was achieved in all patients. During followup no obstructive urinary flow pattern was detected, and early and long-term maximum urine flow rates were comparable.
  
  
  CONCLUSIONS
  No meatal/neourethral stenosis was observed in any patient undergoing a Snodgraft procedure. A randomized trial will be needed to prove that the incidence of meatal/neourethral stenosis is lower after Snodgraft repair compared to routine tubularized incised plate repair.
