Foreskin reconstruction and preservation of a thin distal urethra: a challenge in tubularized incised plate urethroplasty

Abstract

The aim of this retrospective study was to evaluate the functional and cosmetic outcome of tubularized incised plate urethroplasty (TIPU) with preputial reconstruction and preservation of a thin distal urethra when applicable. The records of 64 boys with hypospadias, who underwent TIPU between 2000 and 2007 were analyzed. 33 (52%) underwent foreskin reconstruction and a thin distal urethra was preserved and incorporated in 19 (30%) patients. The Hypospadias Objective Scoring Evaluation (HOSE), Pediatric Penile Perception Score (PPPS), and uroflowmetry were evaluated in 55 boys (86%) after a mean of 4.8 years. All patients had a vertically oriented meatus. The overall rate of fistula occurrence was 9% and of wound dehiscence, 5%. Among 33 preputial reconstructions, two (6%) patients had dehiscence and three (9%) had a fistula. No cases of stricture or stenosis occurred. There were significantly more complications with reconstruction of the foreskin (p = 0.012) and preservation of a thin distal urethra (p = 0.021). Uroflowmetry was normal in 76% of patients. PPPS and HOSE revealed excellent results. TIPU produces excellent cosmetic and functional results with few complications; complications are more common after foreskin reconstruction and use of a thin distal urethra.
