[Surgical treatment of complicated urethral stenosis (54 case reports)].

The authors report their surgical experience of complicated stenosis of urethra in the Department of Urology of the Central Hospital of N'Djaména (Tchad) from 1984 to 1987 (July). The surgical treatment was indicated for the complicated cases of stenosis of the urethra, which were obstructed (less than a quarter of the patients who were admitted for urethra stenosis). Before 1984 the only surgical procedure was called "Chemin de fer: a blind pull-through method with a lot of complications. After 1984 the one stage urethroplasties were used in forty four cases: either with a free full thickness skin graft (DEVINE), or with a vascularized flap (BLANDY'S or ORANDI'S technique). The results are studied with a follow up of 18 months. The urethroplasties with a vascularized flap have had less failures (16%) than with a free full thickness skin graft (33%).
