Preputial flaps to correct buried penis

The authors developed a preputial skin flap technique to correct the buried penis which was simple and practical. This simple procedure can be applied to most boys with buried penis. In the last 3 years, we have seen 12 boys with buried penis and have been treated by using preputial flaps. The mean age is about 5.1 (from 3 to 12). By making a longitudinal incision on the ventral side of penis, the tightness of the foreskin is released and leave a diamond-shaped skin defect. It allows the penile shaft to extend out. A circumferential incision is made about 5 mm proximal to the coronal sulcus. Pedicled preputial flaps are obtained leaving optimal penile skin on the dorsal side. The preputial skin flaps are rotated onto the ventral side and tailored to cover the defect. All patients are followed for at least 3 months. Edema and swelling on the flaps are common, but improves with time. None of our patients need a second operation. The preputial flaps technique is a simple technique which allows surgeons to deal with most cases of buried penis by tailoring the flaps providing good cosmetic and functional results.     

An alternative way to cover ventral penile skin defect in Mathieu technique.

Mathieu technique is used satisfactorily in distal penile hypospadias without chordee or with minimal chordee. After using this technique, a large defect may sometimes appear on the ventral surface of the penis. To cover the defect, a few techniques, including preputial island flap, Byar's flap and Ombrédanne-Nesbit's flap, are used. We describe a new flap to cover the defect more cosmetically. Twenty-four patients ranging in age from one year to 14 years (median age 6.5 years) were operated on. In the patients for whom the defect could not be covered primarily, a longitudinal incision was made along the midline through the penile shaft skin from penile radix up to the border of preputial skin. The relaxed penile skin, which was incised on the dorsal surface, could be approached and sutured easily on the ventral surface without stretching. The new defect that developed on the dorsal surface was closed with the prepuce matching the defect. Nine patients, two with chordee and seven without chordee, underwent this technique. The cosmetic and functional results were excellent in all patients and none of the patient's parents complained about the cosmetic aspect. Only one fistula complication, which healed spontaneously, developed on the 20th postoperative day. Considering these results, we may conclude that excellent cosmetic results can be accomplished by the use of this flap technique.

Surgical correction of congenital megaprepuce

Congenital megaprepuce (CMP) is a rare entity. Two infant boys presented with a tight congenital phimosis resulting in an excessively baggy, urine-filled prepuce and a swollen scrotum. Compression of the scrotum resulted in drainage of urine. We feel this to be a separate entity from a buried penis and recommend early surgery. The phimotic tip of the foreskin was excised and the inner layer preserved to cover the full length of the penile shaft. The outer layer of the foreskin, in reality the penoscrotal junction, was anchored to the base of the penile shaft. A V-shaped edge of ventral skin was excised and the edges approximated, giving the appearance of median raphe. The final appearance was that of a circumcised penis. A third patient awaits operation.

The Cosmetic Results of a Simple Method for Repairing Preputial Skin Defect in Hypospadias

Objective: Hypospadias is a common birth defect of the penis. Besides the abnormal position of the urethral opening, there is usually a ventral preputial defect with preputial redundancy in dorsal shaft. There are many flap procedures for correcting this defect. Here, we present our experience of skin coverage procedure with better cosmetic results. Methods: It is a prospective study on patients with mid-shaft to glandular hypospadias operated from June 2008 to December 2012. The operations were performed by one surgeon in two hospitals and the cosmetic results were evaluated by the surgeon, parents, and another pediatric surgeon by a satisfaction questionnaire. In this procedure, inner prepuce was incised curvilinearly, remaining 5 mm in medial and 8 mm in lateral aspects of the inner prepuce. For skin repair, dorsal flaps were approximated in midline along median raphe. Findings: Sixty-three patients with mean age of 25.75±8.46 (7-93) months were followed up for 7.06±3.34 (2-15( months. There were 4 complications. The overall satisfaction with penile skin coverage was 93.7% for parents and 98.4% for surgeons. Patients’ age and primary site of meatus had a significant correlation with cosmetic results (P<0.05), while urethroplasty techniques and post-operative complications were not significant. Conclusion: Reapproximation of dorsal flaps in midline is a simple method and can be used in most cases of uncomplicated primary hypospadias. By this technique a more normal appearance can be achieved.Key Words: Hypospadias, Urethroplasty, Cosmetic Surgery, Penis

Hypospadias repair using a double onlay preputial flap

 From an anatomical view, a more reasonable blood supply can be achieved in hypospadias repair using a double-faced onlay flap. A urethroplasty was performed in 15 patients with middle or posterior hypospadias using a double-faced onlay preputial flap (DOPF). In this method, the urethral plate is preserved and a double-faced preputial flap is developed. The inner face of the flap is sutured to the urethral plate to create the neourethra and the outer face together with the rest of the dorsal prepuce is used for ventral skin coverage. Postoperative complications occurred in 2 patients: 1 developed a fistula in the subcoronal region and 1 had dorsal skin necrosis and suture disruption of the glanular wings. The overall complication rate was 13%. The DOPF provides a well-vascularized ventral skin cover and reduces the area of avascular dorsal skin. The viability of the neourethra can be evaluated by simply looking at the outer face of the flap. However, the complication rate is similar to that of other techniques.

Penile resurfacing for denuded penis following circumcision

Major loss of penile shaft skin following circumcision has been rarely reported in the paediatric literature and when it occurs is usually due to the injudicious use of monopolar diathermy, infection and poor surgical technique. We report the reconstruction of a penis following complete loss of penile skin due to circumcision. We employed a split-skin graft for the glans and full-thickness graft for the shaft to achieve a more natural cosmetic appearance. This approach has not been described previously in the paediatric literature and should be considered in the unfortunate event of significant penile skin loss.     

Bracka's staged repair of proximal hypospadias--revisiting a versatile technique

ObjectiveProximal hypospadias is associated with poorly defined urethral plate and often with chordee. A two-staged Bracka’s repair is reproducible and has been used routinely in our practice. We present the key steps of this technique on a 13-month-old boy.Patient and methodThis boy presented with proximal penile hypospadias, hooded foreskin and mild chordee. He underwent stage one Bracka’s repair. The steps included: 1) Artificial erection test to define extent of chordee; 2) inner preputial graft harvest and preparation; 3) glans and urethral plate incision down to corpora cavernosa; 4) partial release of chordee by division of aberrant corpus spongiosum, without degloving of penile skin; 5) laying of preputial graft; 6) dressing.ResultThe patient had catheter removed on second, and dressing removed on seventh, post-operative days, without complication. The patient is planned for second stage repair in 6 months. Our standard approach includes either removal of catheter on the second or seventh post-operative day, according to surgeon preference. The three senior surgeons have used this method in 54 patients without significant complication. The graft has taken in 100% of cases.ConclusionThe Bracka’s staged repair of proximal hypospadias is a versatile technique that gives reproducible and sound results.     

The addition of three variants of subcutaneous flaps can improve the results of urethroplasty

Three types of subcutaneous flaps were used in conjunction with urethroplasty in 18 patients. These flaps originated from the inner face of the prepuce in 6 patients, the ventrolateral penile skin in 11, and the dorsal penile skin in 1. The flaps were used to cover the primary urethral repair. Urethroplasty was performed in 7 patients for hypospadias, in 9 for complex urethroclasties fistulae, and in 2 for primary urethral strictures. A variety of surgical techniques were used for the urethroplasties. Two complications were encountered during an average follow-up period of 18 months: loss of a full-thickness skin graft urethroplasty in 1 patient and meatal stenosis in another. The three variants of subcutaneous flaps described in this series add a well-vascularized apron of tissue to a variety of urethroplasties, thus improving the results. Our surgical technique and results are presented in detail. Offprint requests to: H.-G. Mesrobian     

Tubularized incised plate urethroplasty for the treatment of penile fistulas after hypospadias repair

ObjectiveUrethrocutaneous fistula is the most common complication of hypospadias repair. Tubularized incised plate urethroplasty (TIPU) has been used for the management of distal fistulas. This study reports the usage of TIPU in the treatment of large penile fistulas.Materials and methodsBetween April 2002 and September 2012, 15 patients with large penile fistulas who were managed with TIPU were included in the study. The fistulas were sited along the penile shaft from proximal to distal penile localization. Glanular and coronal fistulas were excluded. The surgical technique was completed according to the standard TIPU technique. The surrounding scar tissue of the fistula was circumferentially excised, and the urethral plate at the level of the fistula was incised to provide performance of loose urethral tubularization. A urethral stent was kept for 5–7 days.ResultsThe mean age of the patients was 7.3 ± 3.1 years. Primary operation of these patients was tubularized preputial island flap (n = 6), on-lay preputial island flap (n = 4), and TIPU (n = 5). The sites of the hypospadias fistulas were as follows; penoscrotal (three), mid-penile (eight) and subcoronal (four). Fistulas recurred in two patients after fistula repair. The postoperative follow up of the patients was 12.4 ± 7.7 months.ConclusionTIPU may be used safely for the treatment of fistulas after hypospadias repair.     

The use of a perimeatal-based penile skin flap to cover the repair of a tubularized incised plate urethroplasty: From experimental surgery to clinical practice

ObjectiveTo prospectively evaluate the efficacy and safety of a perimeatal-based penile skin flap for neourethral coverage after repair of distal hypospadias with tubularized incised plate urethroplasty (TIPU).MethodsIn 12 New Zealand white rabbits a ventral urethral defect was created and reconstruction was accomplished with continuous suture. An epithelialized defect-based flap was harvested from the penile skin to cover the repaired defect. The animals were euthanized on the 28th postoperative day and their penises were processed for microscopic examination. In 32 children with distal hypospadias a TIPU was performed. A penile skin flap was created immediately below the distal end of the neourethra and used to cover the urethroplasty.ResultsHistological examinations revealed complete restoration of continuity of the stratified squamous epithelium without evidence of inflammation or fistula formation with full consistency with the underlying papillary reticular and corium. There were no cases of fistula formation. One patient developed meatal stenosis. All patients had a satisfactory cosmetic appearance and excellent functional results.ConclusionThe formation of a perimeatal-based skin flap is a simple and safe method of providing additional cover for the constructed neourethra after TIPU, minimizing the fistula rate.     

Evaluation of distally folded onlay flap in repair of distal penile hypospadias

ObjectiveTo evaluate the results of using a distally folded onlay flap in the repair of distal penile hypospadias, with regard to meatal stenosis, urethrocutaneous fistula and esthetic outcome.Patients and methodsThis prospective study involved 36 patients with mean age 3.2 years (range 1–4); 18 had a shallow urethral plate, 10 a small glans, and 8 had undergone a previous operation but still had available preputial skin. All underwent the elective technique of distally folded onlay flap, which was carried out under general anesthesia using a 4× magnifying loupe. Starting with penile degloving and then harvesting the transverse island preputial flap provides a flap about 1 cm longer than the urethral plate. Two lateral incisions are made along the urethral plate with no need for dissection deep into the glanular wings. The flap is sutured to the urethral plate, leaving 1 cm distal to the tip of the glans, which is folded back to be sutured to the edges of the glanular wings.ResultsThere were no cases of meatal stenosis or requirement for urethral dilatation. Two patients had a urethrocutaneous fistula; one closed spontaneously while the other needed surgical repair 6 months later. Regarding esthetic appearance, 32 were scored good and 4 satisfactory.ConclusionThis versatile technique offers satisfactory results regarding meatal stenosis, urethrocutaneous fistula and esthetic outcome.     

Outpatient catheterless Mathieu repair: how to cover ventral penile skin defect.

A modification of the Mathieu repair eliminating stenting has been described by Rabinowitz which makes the method more convenient for outpatient performance. We report on our experience with this modification with special emphasis on coverage of ventral penile skin defect. To cover the raw area formed on the ventral aspect of penis with the creation of meatal based flap Rabinowitz used Byar's flap. Two different flaps prepared from prepuce were used in this series. In some patients an island flap was used. In others the prepuce was incised transversally on its dorsal aspect and transferred to the ventral surface as a bipedicle visor flap, as described by Ombrédanne and popularized by Nesbit. Twenty-two patients ranging in age from one to twelve years (mean +/- 1SD = 6 +/- 3.28) were operated on using the technique. The meatus was glandular in two, coronal in twelve and distal penile in eight patients. Preputial flap was not used in one patient because the defect was small. Island flap was used in three and Ombrédanne-Nesbit's flap in 18 patients. Complete disruption of the repair occurred in one of the patients in whom an island flap was used. Among 18 patients in whom Ombrédanne-Nesbit's flap was used, one partial necrosis of the preputial flap was encountered which required revision and two urethrocutaneus fistulae occurred which healed spontaneously. The use of the present technique yields a good cosmetic result, a high success rate with minimal complications, and eliminates catheterization; hence, hospitalization is recommended.     

Penile Skin Involvement as the First Presentation of Henoch-Schonlein Purpura Report of Nine Cases and Review of Literature

Introduction:

Involvement of penis is a rare presentation in henoch-schonlein purpura (HSP). The presentations are mainly due to the deposition of immunoglobulin A (IgA) into the vessel walls.In this report, we present the clinical history of nine HSP cases that presented with penile skin involvement.

Case Presentation:

All patients were referred in the acute phase of HSP. Penile skin involvement was evident as erythema, edema, ecchymosis, or induration of prepuce and/or penile shaft, that appeared simultaneously with skin rash in seven patients. Gastrointestinal involvement was positive in six patients. Patients were treated with steroids and follow up visits were normal except for one patient that developed crescentic glomerulonephritis.

Conclusions:

We present nine cases of HSP with penile involvement in order to indicate another rare aspect of HSP and its possible complications as well as its appropriate treatment.     

Urethral plate grafting improves the results of tubularized incised plate urethroplasty in primary hypospadias

ObjectiveWe conducted a competitive efficacy trial in order to examine whether grafting the raw area of the urethral plate (UP) with inner preputial skin in children with primary hypospadias (PH) during tubularized incised plate urethroplasty (TIP) improves the results of the operation.Material and methodsFifty consecutive patients with pathology ranging from glanular to proximal penile PH were randomized into two groups, comparable for age and pathology, to be operated on either with TIP or a grafted TIP (G-TIP) procedure. Three patients failed the re-examination protocol, so the TIP group comprised 23 children aged 9.0 months–9.6 years (mean age 3.4 years) and the G-TIP group comprised 24 children, aged 10.0 months–9.4 years (mean 3.5 years). The patients were followed up for a period of 2–5 years (mean 3.2 years).ResultsWithin the TIP group, we observed the development of fistula with concomitant neourethral stenosis in two cases (8.7%), stenosis without fistula in four (17.4%), and glans dehiscence in one case (4.35%). Within the G-TIP group there was one case of fistula without stenosis (4.16%), no case of neourethral stenosis, and one case of glans dehiscence (4.16%). Two cases of non-slit-like meatus were observed in the TIP group. The results show that the complications of neourethral stenosis are significantly reduced (p < 0.05) in the G-TIP group, as is the total number of complications and unsatisfactory results. The duration of the TIP operation was 72–110 (mean 92) min, and for the G-TIP 100–136 (mean 115) min. No postoperative symptoms were observed that could be attributed to prolonged anesthesia time.ConclusionUP grafting with inner preputial skin, when added to the TIP procedure in the treatment of PH, results in a significantly smaller number of unsatisfactory results, and particularly fewer cases of neourethral stenosis. G-TIP can be used as the procedure of choice in PH patients.     

Two-stage complex hypospadias repair when urethral plate has to be divided: Ventral corporoplasty using a tunica vaginalis flap

ObjectiveTo demonstrate ventral corporoplasty, with tunica vaginalis flap to reconstruct the corpora cavernosa, in a two-stage strategy for proximal hypospadias surgery.MethodsAssessment of residual curvature after complete urethral plate division and transverse superficial cuts in albuginea. Ventral incision of tunica albuginea to elongate the ventral surface of the penis and use of a tunica vaginalis flap to reconstruct the defect in corpora cavernosa. Dorsal preputial island flap was used to cover the penile ventral surface, to be tubularized in a second stage, together with the original urethral plate.ResultsPatient had an uneventful follow-up. Penile aspect was very satisfactory with no residual curvature.ConclusionTunica vaginalis is an attractive alternative for ventral corporoplasty in hypospadia repair and has the advantages of prompt disposability, autologous use, and does not represent an extra cost for treatment.     

Penoplasty for buried penis in infants and children: report of 100 cases

Purpose  The aim of this study is to report single surgeon’s experience in treatment of buried penis in children and describe the surgical technique which was developed by the senior author. Methods  Described surgical technique avoids circumferential incision at the base of the penis and thus prevents formation of post-operative lymphedema. Repair is based on a vertical incision in median raphe, complete degloving of penis and tacking its base to prepubic fascia. Shaft skin is attached to base of penis with vertical mattress sutures. Results  Patient age varied from 1 month to 11.4 years (mean 1.9 years). All patients had good to excellent outcome with uniformly improved visualization of penile shaft post-operatively. There was one case of wound infection successfully treated with oral antibiotics. Revisions were needed in 4% patients. Conclusion  Surgical correction of buried penis in infants and children is safe and effective. Described technique is applicable for essentially all cases of congenital buried penis as well as for iatrogenically entrapped penis after circumcision. In our experience there were no additional procedures required to assure skin coverage of penile shaft. An erratum to this article can be found at     

Utility of tissue expansion in pediatric phallic reconstruction: a 10-year experience

ObjectiveBoys with complex penile anomalies often undergo multiple operations, leaving a paucity of unscarred skin for further reconstructive procedures. Our objective was to evaluate the ability of tissue expansion to provide local skin for successful phallic reconstruction.Materials and methodsEighty boys (mean age of 11.9 years) with hypospadias (n = 42) or epispadias (n = 38) formed the study cohort. All patients had undergone at least one failed reconstructive operation. Indications for tissue expansion included scarcity of penile skin with urethral stenosis, urethrocutaneous fistula, chordee, and/or residual defect. One or two expanders were placed under the skin of the penile shaft and removed at the time of reconstruction.ResultsAverage time between expander placement and reconstruction was 10.9 weeks. Mean follow-up time was 25.3 months. Complications during expansion occurred in 33 patients (41.3%). Twenty-two patients (27.5%) had at least one expander removed prematurely and 46.9% were replaced. Expansion yielded adequate tissue for reconstruction in 76 patients (95.0%). Successful outcomes were achieved in 39 patients after initial reconstruction and 25 patients after further intervention, yielding an overall success rate of 80.0%.ConclusionTissue expansion is a useful tool with an acceptable rate of complications for phallic reconstruction in patients who have failed prior surgical reconstruction.
