Extensive penile skin necrosis after surgery for Peyronie's disease

The clinical case represents the surgical correction of postoperative complications in a patient with Peyronie's disease. The patient underwent flap corporoplasty using an autovein. The late postoperative period in the patient was complicated by extensive necrosis of the penile skin, which required repeated surgery as follows. The first stage of surgical treatment was performed by excision of necrotic tissues of the penile skin. Within 10 days of the postoperative period, chymotrypsin with an ointment containing dioxomethyltetrahydropyrimidine with chloramphenicol was applied to the penile wound surface to prepare the wound for subsequent skin autotransplantation. Further, within 5 days, the polymeric drainage sorbent «Aseptisorb DT» was applied to the wound surface until the wound was cleansed and granulation tissue was formed. The second stage of the surgical treatment performed penile skin replacement plasty with a free perforated skin graft taken from the patient's femoral surface.

Oral Mucosa vs. Penile Skin Flap in Substitution Urethroplasty for Anterior Urethral Strictures: A Systematic Review and Meta-Analysis

Background: The purpose of this study is to compare the effectiveness and safety of oral mucosa and penile skin flaps in the treatment of anterior urethral stricture.Methods: This meta-analysis was carried out according to the principle of preferred reporting items for systematic reviews and meta-analysis (PRISMA) and registered at PROSPERO (CRD42021277688). The Cochrane Library, PubMed, Embase, CKNI databases were searched and reviewed up to Sep 2021. Quality evaluation was performed with Newcastle-Ottawa Scale (NOS) system for non-randomized studies and Cochrane stools for randomized studies. Data synthesis was conducted with RevMan 5.4 software (Cochrane) and a Stata 15.0 environment (Stata Corpor, College Station, TX, USA).Results: After the research screening, eight studies (comprising 445 patients) were finally included in the quantitative analysis. In the success rate comparison, there was no significant difference between oral mucosa and penile skin flaps (oral mucosa vs. penile skin flap, Mantel-Haenszel statistic [M-H] fixed model, OR: 0.80, 95% CI: 0.47–1.34, P = 0.39). There was no significant difference in the post-operative complication comparison (oral mucosa vs. penile skin flap, Mantel-Haenszel statistic [M-H] fixed model, OR: 0.68, 95% CI: 0.40–1.16, P = 0.15). However, considering that the site of oral mucosa is far from the anterior urethra, it may have advantages in operation time through simultaneous operations (oral mucosa vs. penile skin flap, MD: −40.05, 95% CI: −79.42, −0.68, P = 0.046).Conclusion: When the oral mucosal graft was used in the anterior urethra urethroplasty, it had a similar success rate and post-operative complication rate, and oral mucosa substitution had a shorter operation time. This evidence-based medical research further supports the view that oral mucosa is the preferred substitution material for the anterior urethra urethroplasty.

Complex hypospadias reconstruction: Ulaan Baatar technique revisited

Background: Complex hypospadias repair is a challenging issue for the urologists. In Ulaan Baatar technique a distal neourethral tube along with glans is reconstructed in first stage with formation of a controlled fistula between neourethral tube and native urethra proximally. Later in second stage the fistula is closed by traditional technique. Therefore glans and distal urethral tube are not being manipulated during second stage repair and thus it has better cosmetic outcomes.Methods: We reviewed the records of 33 different patients with proximal hypospadias who had undergone Ulaan Baatar repair in last 3 years. 21 patients had multiple previous attempts of hypospadias repair and 12 were primary (naïve) cases with proximal hypospadias.Results: Mean follow up was 18.5 months after first stage and 12.4 months after the second stage. The mean age was 14.1years (ranged 8 to 22 years). Mean time between stage I and stage II was 8 months (range 6-9 months). None of the patients developed fistula, glans dehiscence, meatal stenosis or diverticula formation. All patients had satisfactory cosmetic appearance of glans, distal meatus and shaft.Conclusions: The Ulaan Baatar technique is very safe and effective technique with better cosmetic outcomes and least complication rates. Also the vascularized tunica vaginalis flaps may be used for construction of urethral lumen in complex hypospadias cases when local penile skin is deficient.

A hímvessző bőrének helyreállítása szklerotizáló lipogranuloma okozta deformitás miatt

Összefoglaló. Bevezetés: A hímtag körméretének növelése érdekében, az annak bőre alá bejuttatott zsírnemű anyag szklerotizáló lipogranulomát okoz. Hazánkban a szklerotizáló lipogranuloma okozta hímvessző-deformitások kezelésének legelterjedtebb módszere a két ülésben végzett bőrpótlás. Ennek ellenére a magyar nyelvű szakirodalomban kevés adat áll rendelkezésre a kétüléses műtét eredményességéről és várható szövődményeiről. Célkitűzés: Tanulmányunkban a szklerotizáló lipogranuloma okozta deformitások miatti – két ülésben végzett – hímvesszőbőr-helyreállítással szerzett tapasztalatainkról, a műtét után kialakuló szövődményekről számolunk be retrospektív adatgyűjtés alapján. Módszer: 2008. március 1. és 2020. március 1. között a Debreceni Egyetem Urológiai Klinikáján 17 betegen végeztünk kétüléses hímvesszőbőr-helyreállító műtétet. A szklerotizáló lipogranuloma által érintett bőrt teljes mértékben eltávolítottuk, majd a lecsupaszított hímtagot a herezacskó elülső felszínén kialakított subcutan csatornába helyeztük. A második ülés során a herezacskó bőre alá ültetett hímvesszőt felszabadítottuk. Eredmények: A Clavien–Dindo-beosztás szerint az első ülés után három, a második ülés után egy I. gradusú szövődmény alakult ki; II–V. gradusú szövődményt nem figyeltünk meg. Azon 9 beteg közül, akik mindkét ülésen átestek, 7 beteg elégedett volt a beavatkozás eredményével, 2 beteg korrekciós műtéten esett át fél és 9 évvel a második ülés után. A 8 beteg közül, akik csak ez első ülést vállalták, egy korrekciós műtét történt 4 hónappal a műtét után. Következtetés: A hímvessző szklerotizáló lipogranulomája esetén az érintett bőrterület kimetszése után hímvesszőbőr-helyreállítás szükséges. A herezacskó-bőrlebeny alkalmazásának előnye, hogy a herezacskó színe és elaszticitása a hímvesszőbőréhez hasonló, a tapintás- és erogén érzet megmarad. A kétüléses hímvesszőbőr-helyreállítás kevés szövődménnyel, plasztikai sebészeti jártasság nélkül elvégezhető. Orv Hetil. 2021; 162(35): 1413–1417. Summary. Introduction: Subcutaneous injection of liquid fatty materials to enhance penile girth induce sclerosing lipogranuloma of the penis. In spite of its well known severe consequences there has been a persistent use of this practice in non-medical circumstances. Objective: The aim of this paper is to present our observations with staged penile skin reconstruction for sclerosing lipogranuloma and to evaluate postoperative complications in a retrospective manner. Method: Between 2008 and 2020, 17 patients underwent surgery to treat sclerosing lipogranuloma of the penis by staged penile skin reconstruction at our department. Complete exscision of the involved tissue was performed, then the denuded penile shaft was inserted into a subcutaneous channel on the anterior side of the scrotum during the first stage. The second stage of reconstruction consisted of releasing the penile shaft from the scrotum. The second stage was performed merely on 9 in 17 patients. Results: According to the Clavien–Dindo classification system, 3 grade I and 1 grade I complications occurred in the postoperative period after the first and second stage, respectively. Grade II–V complications were not observed. 7 of 9 patients who underwent both stages were satisfied with the final result, 2 patients had minor correction surgery 6 months and 9 years following the second stage. 1 of 8 patients who underwent only the first stage had minor correction surgery 4 months following the operation. Conclusion: In case of sclerosing lipogranuloma of the penis, excision of the affected tissue and reconstruction of the penile skin are indicated. Advantages of using scrotal skin flaps are that colour and elasticity of the scrotal skin are similar to penile skin, erogenous sensation of the scrotal flap remains intact. Applying staged penile skin reconstruction with scrotal skin flap has the advantage of few postoperative complications and it is easy to perform. Orv Hetil. 2021; 162(35): 1413–1417.

Coronal sulcus–based ventral mucosal flap to help penile coverage in severe concealed penis

IntroductionThere are many techniques to treat congenital concealed penis (CP). Skin resurfacing is the most difficult step in severe cases. We aim to show medium-term results of coronal sulcus–based triangular ventral mucosal flap (CBVMF) as a treatment of prepubertal severe CP, a recently reported technique. We aim to determine whether results are durable and if the technique is associated with persistent mucosal redundancy or with a permanent unequal penile color pattern.MethodsCP cases reconstructed with CBVMF were reviewed. Preoperative complaints, degree of motivation of the child/parent to surgery, satisfaction of parent/child with results, and surgical complications were described.ResultsSeven patients (6 months to 6 years old) were treated with CBVMP. Two patients showed megaprepuce and another was submitted to a limited postectomy 3 years before. One family was not fully satisfied (expected “bigger penis”), but acknowledged that the penis was now well exposed. No child talked about the problem preoperatively, but all of the boys were fully satisfied with the results of the surgery and verbalized this in the interviews. Flap edema resolved after 3 months in all but one patient. The flaps assumed the color of penile skin in the medium term.ConclusionsCBMVP results were satisfactory. Serious complications did not occur. Flap edema does not persist in the medium term, and redundancy was not a problem. The color of the flap tended to evolve into a pattern similar to the penile skin.

Acrylate application of the penis in the surgical treatment of hypospadias in boys: multicenter study

Introduction. One of the most important aspects of the treatment of hypospadias is the use of a postoperative dressing. Currently, many types of dressings are available, with their advantages and disadvantages. The postoperative dressing should be easy to use, able to control edema, prevent bleeding and the formation of hematomas, and prevent other possible complications. In the last decade, there have been publications in which cyanoacrylate adhesives were used with good results in surgical operations on the penis. Materials and methods. The study included 77 boys who underwent correction of the distal form of hypospadias from January 2018 to December 2020. The first group consisted of 47 boys, whose penile skin was applied with cyanoacrylate tissue glue after the operation was completed. The second group included 30 boys who used a standard circular adhesive bandage. All patients received the same type of treatment. Results. In the early postoperative period, 16 (20.78%) patients had various complications associated with bandages, which were distributed according to the Clavien-Dindo classification and assigned to grade I-II, according to clarien-Dingo classification. In the group of acrylate application, five (10.6%) patients needed to perform manipulations on the penis in the form of repeated adhesive application. When using an elastic self-binding bandage, all patients needed to remove the bandage, and 11 (36.7%) patients needed additional bandages (χ2=6.038; p=0.015). Conclusions. The use of acrylate application is an alternative to standard postoperative dressings in the treatment of hypospadias. The technology of use can be easily trained and reproduced by surgical personnel.
