34 girls aged 3-12 years (mean age 7 years) with vesicoureteric reflux and 'distal urethral stenosis' were treated operatively by Otis' urethrotomy. They were investigated clinically and radiologically with regard to urinary tract infection, renal growth and scarring. At the end of the observation period, urinary tract infection was still present in 21%, vesico-ureteric reflux in 26%, decreased renal length in 15% and renal scarring in 23%. Compared to antibiotic therapy, Otis' urethrotomy gives no better results in curing infections or reflux or preventing renal scars.
34名年龄在3至12岁（平均年龄7岁）、患有膀胱输尿管反流和“远端尿道狭窄”的女孩接受了奥的斯尿道切开术治疗。对她们进行了关于尿路感染、肾脏生长和瘢痕形成的临床及影像学检查。在观察期结束时，21%的患儿仍存在尿路感染，26%存在膀胱输尿管反流，15%肾脏长度缩短，23%存在肾脏瘢痕形成。与抗生素治疗相比，奥的斯尿道切开术在治愈感染或反流以及预防肾脏瘢痕方面并未取得更好的效果。
