目的
2
探讨游离包皮内板尿道板镶嵌联合Buck筋膜整体覆盖技术的尿道成形术(Inlay-BFIC)在尿道下裂手术中的实用性及疗效。
方法
2
回顾性分析从2018年1月至2020年8月,85例阴茎头舟状窝处尿道板宽度为3~5 mm的尿道下裂手术患者的临床资料。根据技术开展的时间进行分组,其中A组38例连续病例(2018年11月至2020年8月),包括5例尿道下裂术后再手术病例,采用Inlay-BFIC的尿道成形术。手术方法:在尿道板纵切后,取薄全层游离包皮内板皮片镶嵌于切开的尿道板中间,成形尿道后,将预先保留的Buck筋膜与阴茎头两翼组织在中线处缝合,作为中间层整体覆盖新成形的尿道;B组47例连续病例(2018年1月至2018年12月),均为初次手术病例,采用传统尿道板纵切卷管TIP手术;记录患者围手术期数据和术后随访资料,对结果进行统计学分析。

结论
2
游离包皮内板尿道板镶嵌结合BUCK筋膜整体覆盖技术(Inlay-BFIC)治疗尿道下裂,在尿瘘、尿道狭窄、尿道憩室和残留阴茎下弯的发生率以及术后尿流率上与传统TIP手术相仿,但可以显著减少阴茎头和尿道裂开的发生。
Objective
2
To investigate the practicability and efficacy of Inlay preputial graft urethroplasty combined with Buck fascia integral covering technique (Inlay-BFIC) in the treatment of hypospadias.
Methods
2
A total of 85 surgeries of hypospadias with urethral plate width of 3-5mm at the level of the glans navicular fossa from January 2018 to August 2020 were retrospectively analyzed. The patients were divided into two groups according to the time of technique applied. Group A: from November 2018 to December 2020, 38 consecutive patients, including 5 re-operation cases, were operated with Inlay-BFIC urethroplasty. Surgical approach: a thin and full-thickness free preputial graft was embedded in the middle incision of the urethral plate when patients underwent TIP procedure; after the urethroplasty, the pre-reserved Buck fascia combined with glans wings was sutured at the midline as an intermediate layer to cover the neo-urethra. Group B: from January 2018 to December 2018, 47 consecutive primary hypospadias patients underwent conventional TIP procedure. The data of perioperative period and postoperative follow-up were recorded and analyzed statistically.
Results
2
Totally 85 patients were repaired by one-stage procedure. Group A with Inlay-BFIC vs. group B with conventional TIP: the mean age (39.46±34.66)
vs.
30.23±26.02) m,
t
=1.362,
P
=0.178, the mean length of penis (3.53±1.00)
vs.
(3.46±0.76) cm,
t
=0.373,
P
=0.710, the mean width of glans (1.32±0.36) cm
vs.
(1.37±0.22) cm,
t
=-0.779,
P
=0.438, the mean length of urethroplasty (2.10±0.68)
vs
.(1.92±0.61) cm,
t
=1.282,
P
=0.203. There was no significant difference between the two groups. The preoperative degree of ventral curvature and the mean operative time between group A and group B were (28.29±21.38)
vs.
(19.68±7.62)°,
t
=2.364,
P
=0.023 and (135.29±39.79)
vs.
(96.60±27.21) min,
t
=5.107,
P
=0.000. There was significant difference between the two groups. The postoperative follow-up time was 4 to 36 months. There were 2 cases of urinary fistula in Group A and 6 cases in Group B (
χ
2
=1.387,
P
=0.239), 1 cases of urethral stricture in Group A and 3 in Group B (
χ
2
=0.659,
P
=0.417). There was no significant difference between the two groups. There was no recurrent ventral curvature and urethral diverticulum in both groups. There were 4 cases of glans or urethral dehiscence in Group A and 17 cases in Group B (
χ
2
=7.428,
P
=0.006). There was significant difference between the two groups. Fifteen patients in each group received urinary flow rate test. There was no significant difference between two groups in maximum flow rate (Qmax), average flow rate (Qavc), flow time (FT) and voided volume (V).
Conclusions
2
For the treatment of hypospadias by Buck fascia integral covering technique combined with Inlay preputial graft urethroplasty, the incidence of urinary fistula, urethral stricture, urethral diverticulum, residual penis curvature and postoperative urinary flow rate are similar to those of conventional TIP procedure, but it can significantly reduce the occurrence of glans or urethral dehiscence.
