Objective To present the experience of hypospadias repair using the tubularized incised plate urethroplasty (Snodgrass procedure). Methods FromMay 2001 to November 2004, 82 patients with hypospadias underwent the Snodgrassprocedure and the clinical data were analysed retrospectively. The mean age was5 years (1.5 to 16 years). These cases were divided into: the earlier stage group(34 cases) and the later stage group (48 cases); the proximal group (19 cases)and the distal and middle group (63 cases); the primary operational group (49 cases) and the reoperational group (33 cases). Results Fistulas ocurred in 12 patients (14.6%), complete glans dehiscednce in 1 case. Fistula were as follows: 11 cases in the earlier stage group (32.4%) and 1 case in the later stage group（2.1%）;2 cases in the proximal group (10.5%) and 10 cases in the group of distal and middle group (15.9%); 8 cases in the primary operational group (16.1%) and 4 cases in the reoperational group (12.1%). There was statistically significant difference in the incidence of fistula between the earlier stage group and the later stage group (Plt;0.01). There was no statistically significant difference between the proximal group and the distal and middle group, between the primary operational group and the reoperational group (Pgt;0.05). All patients were followed up more than one month. The neo meatus was innormal position. The results of penile cosmetic and urethral function were satisfactory. Of these cases, 15 were followed up 1.5-6.0 months. The average flow rate was 7.8 ml/s(6.8-10.5 ml/s). The mean of maximum flow rate was 10.5 ml/s (8.8-14.5 ml/s).Conclusion Excellent neourethrol functional and superior casmetic resalts with low rate of complication can be gained by using tubularized incised plate urethroplasty for the cases of hypospadias without chordee or with mild chordee. But the preputialflap procedure should be chosen in condition that the hypospadias was association with obvious chordee.
目的:探讨医源性隐睾的病因,预防和治疗特点。方法:回顾分析我院治疗的16 例医源性隐睾患儿,其中睾丸鞘膜积液术后7 例,腹股沟斜疝术后8 例,尿道下裂术后1 例。结果:16 例均接受手术治疗,10 例睾丸存在不同程度的萎缩,其中1 例睾丸完全萎缩,行睾丸切除。术后随访12 例,睾丸均在阴囊内,但发育较健侧差。结论:降低医源性隐睾发病率的根本措施是防止其发生,尽量减少不正确的医疗行为,并做到早期发现,早期行手术治疗。
Objective To discuss the severity grading and procedure design of concealed penis. Methods Between June 2004 and April 2008, 196 cases of concealed penis were surgically corrected. The age ranged from 1 year and 4 months to 44 years, with a median of 9 years. They presented with inconspicuous penis and abnormal cavernosa development. Four cases compl icated by glanular hypospadias and 3 cases by penile epispadias. They were classified as mild in 49 cases, moderate in 109, and severe in 38 according to severity. Surgical procedures were selected based on varied anatomical changes in different categories. Results All the patients got satisfactory appearance immediately after surgery. No voiding problem, wound infection, and skin necrosis were found. With 6 months to 48 months (mean 16 months) follow-up, most patients achieved good results and the penile appearance resembled that after circumcision. Mild penile retraction was noted in 1 moderate case and 1 severe case; and recurrence occurred in another one, the result was satisfactory after reoperation. Conclusion Various surgical procedures can be adopted for concealed penis. The key point is to design procedures according to the anatomical abnormalities.
