内視鏡的尿道切開術を施行した小児外傷性尿道完全断裂

A CASE OF PEDIATRIC URETHRAL DISRUPTION BY STRADDLE INJURY: SUCCESSFUL ENDOSCOPIC URETHROTOMY

　症例は11歳，男児。鉄棒の上に騎乗状態で会陰部を強打，その後の会陰部疼痛，腫脹，肉眼的血尿を主訴に当科を受診。膀胱尿道造影にて尿道球部における完全断裂を認めたため，経皮的膀胱瘻を緊急留置した。2か月の経過をみたのち内視鏡的尿道切開術を施行した。術後6か月経過した現在，4週間に一度程度のブジーで良好な排尿を得ている。

An 11-year-old boy was referred to our department with a compliant of perineal pain and hematuria due to straddle injury. Retrograde urethrography revealed complete urethral disruption near the membranous urethra, and percutaneous cystostomy was immediately placed. The length of the obstruction was 2.7 cm. After 2 months, endoscopic urethrotomy was performed using 13.5 Fr resectoscope (KAIBA UNIVERSAL) guided by the ureth-ral sound and light of fiberscope from the cystostomy. After establishing the continuity of the urethra, a tip-holded 12 Fr balloon catheter was indwelled.
