Background: The complications after hypospadias repair still occurred in spite of much advancement of type of suture materials and suture techniques. This study offers new suture technique trying to improve the outcome of hypospadias repair.
Methods: This study included 23 hypospadias cases (11 distal penile, 7 mid penile, 5 proximal penile hypospadias). The standard Tabularized Incised Plate (TIP) technique was used in all cases, but the suture technique is faraway, where the two suture limbs passed under the urethral edges. Every suture was tied faraway of urethral edges by about 1cm on one side. Then, the penile skin closed as usual. Lasheen urethral stent was used for two weeks. The mean follow up period was 12months.
Results: The Suture is transverse mattress, the distance between its limbs and every suture was about 3mm. when these sutures were tied bring more soft tissue in midline and inversion urethral plate edges inside the urethra. Healing period was 2 weeks. No urethra-cutaneous fistula or meatal stenosis or penile curvature were noticed during period of follow up.
Conclusion: Faraway suture technique in hypospadias repair is easy , has short learning curve, and associated with good physiological urethra and penile anatomy.
In hypospadias the urethral meatus open at ventral surface of penis or perineum other than the glans tip. Hypospadias is the most common congenital anomalies (0.3%) of external male genitalia . Hypospadias correction is surgical and still represents challenge in reconstructive surgery . Complications of hypospadias repair are many as urethral fistula, urethral stenosis, complete failure, and meatal stenosis, and ranged from 13 to 64% [3,4]. Many risk factors are well known as severity of hypospadias and repair technique, but still other factors are underestimated [5,6]. Suture method of every hypospadis repair is important step which affect the outcome of surgery. This study offers faraway suture technique in hypospadias repair.
The idea of this study was approved by Ethical Committee of General Surgery Department, Zgazig University, Egypt at January 2018. Twenty three hypospadias patient (11 distal penile, 7 mid penile, 5 proximal penile hypospadis cases) were included in this study. The standard TIP was used in all cases, but suture technique to incised plate is different (faraway suture technique). The suture take from 1 cm on one edge of urethral plate, go through soft tissue under both the urethral edges. The needle and thread (Vicryle 4/0) appear on 1cm of other urethral edge and return back to make other suture limb (transverse mattress suture). Multiple faraway sutures were taken to reconstruct neo-urethra and configurate normal glans Figures 1,2. After finishing of putting enough number of faraway sutures, the sutures were tied and penile skin closed as usual TIP technique. Lasheen urethral stent  was stay in its position for 2 weeks Figures 3,4. The follow up period ranged from 6 to 16 months (mean was 12 months).
The number of sutures was varied according to distance between urethral opening and glans tip. The distance between every suture and other was about 3mm. The urethral edges were inverted inside the urethra when sutures tied. The wound healed well within two weeks. No deep infection or abscess formation noticed in any cases. The technique was comfortable in all cases. No urethral fistula or meatal stenosis or urethral stricture were reported during period of follow up.
Many techniques and their modifications are presented for hypospadias repair to improve outcome results [8,9]. The most serious and common complications are urethral fistula and complete failure of technique. Known factors were accused for occurring of these complications as distance between urethral opening and glans tip, presence of chordee, and scar at ventral aspect of penis [10,11]. But until now other risk factors still are unknown . I think the suture technique is one of these risk factors. When, the sutures were putting on both urethral plate edges will leading to eversion of urethral plate edges into soft tissue with occurring of urethral fistula. More than this, much stitches on the urethral plate edges can be producing ischemia and complete failure or fistula. The urethral edges sutures debris reacted as foreign bodies producing deep infection and abscess formation or stitch sinus followed by urethra-cutaneous fistula. Our suture technique in hypospadias repair, was done faraway of urethral plate edges. The suture limbs passed under the urethral plate. So, when the suture limbs were tied leading to inversion of urethral edges inside the urethra and maintain the blood supply of edges producing good healing in short time. The knots were lying faraway of reconstructed urethra no sutures debris leading no reaction and no deep infection.
Our suture technique in hypospadias repair has short learning curve and associated with good results and free of complications.
