ENDOSCOPIC SURGERY IN PEDIATRIC UROLOGY

At our Department endoscopic operations were performed in 201 pediatric patients during the past 9 years (1974-1982): posterior urethral valve 32 cases, anterior urethral valve 4 cases, congenital bulbar urethral stenosis 135 cases, acquired urethral stenosis 16 cases, bladder neck contracture 8 cases and ureterocele 6 cases. Miniature pediatric resectoscope of 10 or 13 Charriere were used. The results of transurethral valve resection for the posterior or anterior urethral valve were quite satisfactory. Good results were obtained by optic internal urethrotomy for the congenital bulbar urethral stenosis, regarding vesicoureteral reflux, enuresis nocturna or recurring urinary tract infections. In cases of acquired urethral stenosis consisting of hard scar tissue, optic internal urethrotomy must be done several times and the results were mostly satisfactory. Transurethral resections against bladder neck contracture were ineffective in our hands, probably because of the secondary nature of the bladder neck contracture in children. Indications of transurethral surgery in ureterocale are also described.
