[Treatment of hypospadias in childhood]

The aim of the paper is to compare different techniques of correction of hypospadias with the author's own group of patients and to compare the results with those achieved at other departments. Between 1992-1999 at the Department of Paediatric Surgery, Teaching Hospital Motol 348 operations were made in 219 boys. A plastic operation with a distal shift of the urethra a and conization of the glans in 112 patients predominated. Other methods included in 39 patients the creation of a ventral circumference of the urethra from the inner laver of the prepuce while preserving the urethral plate ("onlay island flap") and a parameatally everted flap according to Mathieu in 11 patients. A plastic operation by complete tubulization of the inner laver of the prepuce was used in 19 patients, in 2 boys the method of Duplay-Byars tubulization of the urethral plate. In one patient the urethra was replaced by a free flap as described by Nove Josserand. Another 129 operations included formerly used and now abandoned two-stage operations to straighten the penis, operations to reconstruct the prepuce and operations on account of complications. The latter comprised 16.4% fistulae, 9.58% dehiscences and 1.36% strictures.
