OBJECTIVETo review and summarize the experience of urethral reconstruction using lingual mucosal graft for the treatment of complex hypospadias.

METHODSWe evaluated the methods using lingual mucosal graft for the treatment of complex hypospadias. The dorsal inlay graft method and the tube graft method were used in our study.

RESULTSFrom Nov. 2010 to Oct. 2011,21 cases were treated. All the cases had at least one failed hypospadisa surgery before. The dorasl inlay grafting technique was used for 16 patients, the tube grafting technique was carried out in 5 patients(2 cases received Tube + Duply method). The follow-up period ranged from 3 months to 12 months (by average 6 months). The success rate of the methods was 61.9% with complications in 8 cases. Urethral fistula developed in 3 patients and urethral stricture developed in 5 patients. All cases who suffered stricture received the tube grafting technique. The fistula and urethral stricture were occurred at the site of the urethral termonoterminal anostomosis. Urethral stricture is the most common complication after the tube graft method for the treatment of the complex hypospadias.

CONCLUSIONSHarvesting the lingual mucosal graft is feasible and easy to perform. The complex hypospadias repair technique using lingual mucosal graft method provides good results. There fore it should be one of the preferred techniques for complex hypospadias repair. The dorsal inlay grafting technique has lower complication rate than the tube grafting technique. Early and regular urethral sounding should be carried out when patients received the tube graft method.

OBJECTIVETo summarize the experience of urethral reconstruction using circular fasciocutaneous flap for the treatment of complex anterior urethral strictures.

METHODThe circular fasciocutaneous flap was harvested from the distal penile shaft or foreskin. Then the circular configuration was converted into longitudinal strip of skin which was rotated to ventral side to repair the exposured urethral strictures using the ventral onlay method. The surveillance protocol after urethroplasty was urination observation, regularly uroflowmetry and urethrography examination.

RESULTSFrom Nov. 2006 to Oct. 2012, 15 cases were treated. The mean age was 45 years (20-76 years) and mean follow-up period was 18 months(3 months-3 years). Stricture was caused by chronic urethritis in 4 cases, long-term urethral catheterization in 3 cases, transurethral perfusion chem other aphy in 3 cases, transurethral prostatectomy in 3 cases and hypospadias after surgery in 2 patients. The mean stricture length was 7.0 cm (3.5-12.0 cm). The overall success rate was 80.0% (12/15). Recurrence stenosis was noted in 2 cases and diverticulum formation in 1 case.

CONCLUSIONSThe penile circular fasciocutaneous flap can be used for anterior urethral stricture in nearly any length. The flap has the characteristics of hairless, adequate mobile and length, well-vascularized pedicle and easy to harvest. The onlay reconstruction provides excellent cosmetic results, less trauma, higher success rate. Therefore it should be one of the preferred techniques for complex anterior urethral stricture repair.
