[Bladder wall urethroplasty in the treatment of urinary incontinence caused by congenital cervico-urethral malformations].

Twelve patients with urinary incontinence from congenital cervico-urethral malformations were treated by bladder wall urethroplasty. Operation was that of Leadbetter (16 times) or Tanagho (twice) type. Results were satisfactory in 5 patients, poor in the other 7 cases: 6 children required endoscopic resection of the neck malformation to improve bladder retention, but this failed to provoke deterioration of the acquired continence. The relevant literature is reviewed, the commonest techniques mentioned, and factors affecting results analyzed. Essential factors appear to be the state of the bladder, the contractility of the bladder tissue used for urethroplasty, and residual bladder capacity which depends on initial capacity. Final evaluation of efficacy of treatment requires long-term follow up, continence sometimes improving at puberty.
