To review the midterm results of tubularized incised plate (TIP) urethroplasty (Snodgrass method) in reoperative patients with distal or midpenile hypospadias. The results of TIP urethroplasty in 37 patients who had previously failed hypospadias repair were reviewed. Of the patients, 21 (56.8%) had coronal, 11 (29.7%) had subcoronal, and 5 (13.5%) had midpenile hypospadias. The mean age was 4.1 (2-16) years. Twenty-three patients had one operation and 14 patients had two operations previously. Of all the patients, 14 did not have a foreskin because of circumcision. The urethral plate had been disturbed in 6 patients, but there was not apparent scarring of the plate. Postoperative follow-up was 2.3 years with a range of 1.1-3.9 years. Genital examination, urethral calibration, and uroflowmetry were performed in control. Satisfaction of the families about the function and appearance of penis was also evaluated. Successful functional and cosmetic results were achieved in 29 patients (78.4%). All the families were happy with penile aesthetic appearance. The urethral plate seemed healthy at the operation in nine patients who had undergone TIP urethroplasty before and the outcomes were successful in eight of them. The operation was successful in 19/23 (82.6%) patients who had undergone one operation before and in 10/14 (71.4%) patients with two operations as well (P < 0.05). In addition, sufficient outcomes were obtained in also 11 of the 14 patients with circumcision. The success rate was higher in patients <5 years (P < 0.05). The rate was also higher during the recent period (2001-2003) since the experience we had increased (P < 0.05). TIP urethroplasty was unsatisfied in four of the six patients who had had disturbed urethral plate before and in five of eight patients who did not have sufficient amount of dartos tissue for flap to cover neourethra. Complication was observed in eight patients (21.6%): four had a pinpoint fistula, two had wound dehiscence, one had meatal stenosis, and one had mild meatal regression and a short neourethral stricture. All of these complications were repaired successfully at a later date. The mean hospital stay was 4.6 days. TIP urethroplasty provides good functional and cosmetic midterm outcomes in most of the reoperative patients with distal or midpenile hypospadias unless contraindicated by previous resection or gross scarring of the urethral plate. This procedure seems not to disturb the urethral plate and, therefore, it can be applied on reoperative patients who had undergone TIP urethroplasty before. It can also be used in a circumcised patient when there is a lack of foreskin.
回顾管状切开板(TIP)尿道成形术(Snodgrass法)治疗阴茎远端或中段尿道下裂再次手术患者的中期结果。回顾了37例既往尿道下裂修复失败患者行TIP尿道成形术的结果。患者中,21例(56.8%)为冠状沟型尿道下裂,11例(29.7%)为冠状沟下型尿道下裂,5例(13.5%)为阴茎中段尿道下裂。平均年龄为4.1(2 - 16)岁。23例患者曾接受过1次手术,14例患者曾接受过2次手术。所有患者中,14例因行包皮环切术而无包皮。6例患者的尿道板受到干扰,但尿道板无明显瘢痕形成。术后随访2.3年,范围为1.1 - 3.9年。进行体格检查、尿道扩张及尿流率测定。同时评估家属对阴茎功能和外观的满意度。29例患者(78.4%)获得了成功的功能和美容效果。所有家属对阴茎的美学外观均满意。9例既往接受过TIP尿道成形术的患者术中尿道板看起来健康,其中8例手术成功。曾接受过1次手术的患者中19/23(82.6%)手术成功,曾接受过2次手术的患者中10/14(71.4%)手术成功(P < 0.05)。此外,14例接受过包皮环切术的患者中11例也获得了满意的结果。年龄<5岁的患者成功率更高(P < 0.05)。自经验增加后的近期(2001 - 2003年)成功率也更高(P < 0.05)。6例既往尿道板受到干扰的患者中有4例TIP尿道成形术效果不满意,8例没有足够肉膜组织用于覆盖新尿道的患者中有5例效果不满意。8例患者(21.6%)出现并发症:4例有针尖样瘘管,2例伤口裂开,1例尿道口狭窄,1例有轻度尿道口退缩及新尿道短段狭窄。所有这些并发症均在后期成功修复。平均住院时间为4.6天。TIP尿道成形术为大多数阴茎远端或中段尿道下裂再次手术患者提供了良好的中期功能和美容效果,除非既往尿道板切除或严重瘢痕形成存在禁忌。该手术似乎不会干扰尿道板,因此可应用于既往接受过TIP尿道成形术的再次手术患者。当缺乏包皮时,也可用于接受过包皮环切术的患者。
