To review our results of patients who underwent repeat hypospadias surgery using local skin flaps with preservation of the urethral plate.
We retrospectively reviewed the medical records of all patients who underwent a reoperative hypospadias repair using the urethral plate between 1988 and 1996. A total of 53 patients were identified who developed either a large fistula (47 patients) or severe stricture (6 patients) after the initial repair. Seventeen patients underwent a repeat Mathieu flip-flap and 36 an onlay flap. The mean age at the time of surgery was 5.2 years (range 1 to 27). The mean duration of follow-up was 17 months (range 6 to 108).
The initial failed hypospadias repair was corrected with a single procedure in 44 (83%) of the 53 patients. The 9 patients who had further complications required 17 additional procedures. A meatal-based flap had been used in 4 of these patients and an onlay flap in 5. Three of the 9 patients who had further complications presented with urethral strictures after the previous repair.
Fistula and stricture are common complications of hypospadias surgery. The use of the urethral plate in primary repairs has helped decrease the complication rate. We report the effectiveness of using local skin flaps and preserving the urethral plate in complex reoperative hypospadias surgery. These techniques were successful in 83% of these challenging patients. Patients with stricture after hypospadias surgery are at increased risk of further complications.
回顾我们使用保留尿道板的局部皮瓣进行重复尿道下裂手术的患者结果。
我们回顾性分析了1988年至1996年间所有使用尿道板进行再次尿道下裂修复手术患者的病历。共确定了53例患者,这些患者在初次修复后出现了大瘘管(47例)或严重狭窄(6例)。17例患者接受了重复的马蒂厄翻转皮瓣手术,36例接受了嵌合皮瓣手术。手术时的平均年龄为5.2岁(范围1至27岁)。平均随访时间为17个月(范围6至108个月)。
53例患者中有44例(83%)通过单次手术纠正了最初失败的尿道下裂修复。另外9例出现进一步并发症的患者需要额外进行17次手术。其中4例患者使用了基于尿道口的皮瓣,5例使用了嵌合皮瓣。9例出现进一步并发症的患者中有3例在上次修复后出现尿道狭窄。
瘘管和狭窄是尿道下裂手术的常见并发症。在初次修复中使用尿道板有助于降低并发症发生率。我们报告了在复杂的再次尿道下裂手术中使用局部皮瓣并保留尿道板的有效性。这些技术在83%的这类具有挑战性的患者中取得了成功。尿道下裂手术后出现狭窄的患者发生进一步并发症的风险增加。
