Fourteen patients with hypospadias were treated surgically for either an enlarged prostatic utricle (6) or vagina masculina (8). Six vaginae masculinae were removed by an extravesical abdominal approach. One enlarged prostatic utricle was removed by the perineal approach. Three enlarged utricles were removed by an abdominoperineal approach. The transtrigonal approach was recently used for three enlarged utricles and one vagina masculina in four patients. Surgical results in these 14 patients were satisfactory. One post-operative complication of transient mild bilateral vesicoureteric reflux was seen after a transtrigonal removal of an enlarged utricle. Potency was not affected in any approaches in four patients who were older than 12 years. The transtrigonal approach was found to be the best for good exposure of the lesion.
14例尿道下裂患者因前列腺囊增大（6例）或男性假两性畸形（8例）接受了手术治疗。6例男性假两性畸形通过膀胱外腹部入路切除。1例增大的前列腺囊通过会阴入路切除。3例增大的前列腺囊通过腹会阴联合入路切除。最近，经三角区入路用于4例患者的3例增大的前列腺囊和1例男性假两性畸形。这14例患者的手术结果令人满意。在经三角区切除增大的前列腺囊后，出现了1例短暂性轻度双侧膀胱输尿管反流的术后并发症。4例年龄超过12岁的患者在任何手术入路中性功能均未受影响。发现经三角区入路最有利于充分暴露病变。
