“…Furthermore, we found that vascular distribution on the peduncle island skin flap was very regular. The distribution law pertaining to blood vessels found in the deep foreskin region as summarized in this study was similar to the general blood vessel distribution law described by Cağrı Savas et al (24). We suspect that the latter law reflects the former law.…”

“…This allowed superficial and deep vessels in the foreskin to be displayed in a clear hierarchy to be easily identified (Fig 1A). As Cağrı Savas et al (24) did not perform that step, direct transillumination with a cold light source did not help to distinguish between superficial and deep vessels. As a result, Cağrı Savas et al (24) observed the distribution of all superficial and deep vessels, and the deep vessels were thicker than the superficial vessels.…”

“…Cağrı Savas et al (24) reported that microvessel density was significantly decreased in hypospadiac children, and was negatively correlated with the severity of the condition. This finding suggests that blood supply to the neourethra or the occurrence of postoperation complications may be associated with microvessel density.…”

Vascularization of vessel pedicle in hypospadias and its relationship to near‑period complications

The present study evaluated the relationship between the vascularization of vessel pedicle and the near-period complication by assessing the surgery effect and recognizing the blood supply of the material for urethra reconstruction and collected the follow-up of the hypospadias patients after the operation. We illuminated the prepuce by a lighting technique using cold light and then photographed, and recorded the distribution and the quantity of vessels. Then classified, analyzed and summarized the vascularization of vessel pedicle. Patients who were repaired by Duckett technique were followed up for 1–5 months after the operation. We classified vessel pedicle vascularization in hypospadias cases into four patterns based on the predominant blood vessels. The number of predominant vessels had no exact relationship to the meatal location. The incidence of fistula and stricture had no exact relationship to the number of predominant vessels. In conclusion, there is no exact congruent relationship between the types of vascularization with the meatal location. Vascularization of vessel pedicle had no exact relationship with urethral fistula or stricture.

“…Indeed, recent data hypothesized that the blood supply of the prepuce could be congenitally hypoplasic in hypospadic patients . This could result in a failed surgical repair or in the development of complications.…”

Coverage of urethroplasty in pediatric hypospadias: Randomized comparison between different flaps

et al. 2013

Abbreviations & AcronymsObjectives: The use of covering urethroplasty with flaps in hypospadias surgery has been well recommended. Various techniques have been described for flap harvesting. The aim of the present study was to compare the outcome and complication rate of dorsal preputial flaps and ventral dartos flaps. Methods: A total of 130 patients were prospectively evaluated from January 2008 to December 2011. Using the tubularized incised plate urethroplasty procedure, urethroplasty was carried out by a single surgeon. Patients were randomly divided in two groups: group A (57 patients), in which a preputial flap was carried out using three different techniques; and group B (73 patients), in which a single or a double ventral dartos flap was used. Results: A total of 41 complications occurred in 24 patients. Urethrocutaneous fistulas were observed in 14.9%, quite equally distributed between groups A and B. There was only one urethrocutaneous fistula in a patient treated with the double ventral dartos flaps. Five cases (3.8%) of glans dehiscence were observed: four after single ventral dartos flap and one after dorsal preputial flap. Six patients in group A and seven in group B experienced meatal stenosis. In three cases of iatrogenic torsion of the penis, a dorsal preputial flap was laterally transposed. Finally, a lower complication rate was observed for double ventral dartos flap versus the other techniques. Conclusions: The use of a double ventral dartos flap should represent the first-line technique for coverage of distal urethroplasty.
