【摘要】 目的　对一期膀胱粘膜尿道成形术和游离包皮内板尿道成形术治疗尿道下裂的长期疗效进行评价。方法　统计分析我院１９７７ 年１ 月～１９９７ 年１２ 月尿道下裂病例，共施行尿道成形术治疗１４ 岁以下小儿尿道下裂５７３ 例次。而运用一期膀胱粘膜尿道成形术或游离包皮内板尿道成形术治疗５６４ 例次，占同期尿道成形术的９８ ．４％ 。结果　上述两种方法治疗尿道下裂成功率为８６ ．９％ 。从１９９０ 年起由于可吸收化学合成缝线在尿道成形术中的广泛应用，以及手术技术、护理等方面的改进使尿道成形术的成功率有了进一步的提高。结论　游离膀胱粘膜或包皮内板行尿道成形术是治疗尿道下裂的一种较好的方法；两种手术方式的结合运用可适应于各类需尿道成形术治疗的尿道下裂患者。更多还原
