Herein we describe a new surgical approach that incorporates a partially de-epithelialized mid-perineal scrotal flap (MPSF), used as interposition flap, that can be used in almost all patients with RUF after radiotherapy regardless of having or not a concomitant stricture or contracture of the posterior urethra or bladder neck that might require a simultaneous urethroplasty. METHODS: From March 2019 to March 2021 3 men with complex RFU that had failed previous intent of surgical correction underwent surgical repair by means of the MPSF technique.In all cases the RUF is stented leaving a ureteric catheter inserted through the urethra and exteriorized through the anus.An inverted trapezoidal incision centered over the mid raphe is made in the perineum with the proximal aspect of the lateral incisions starting at the level of the ischial tuberosities. The distal aspect of the trapezoidal flap reaches the mid portion of the scrotum. A mid-perineal scrotal flap (MPSF) is harvested that incorporates all the subcutaneous tissue between the skin and the bulbar urethra following the surgical technique described by Gil-Vernet et al. for the elevation of scrotal skin flaps for urethroplasty. During this maneuver the testicles surrounded by the tunica vaginalis are completely freed and positioned temporarily over the lower abdomen. The complete bulbar urethra is visible and allows resection and closure of the fistulous tract. In case that a urethral stricture is associated with the fistula an anastomotic urethroplasty can be fashioned. To avoid recurrence of the fistula the distal aspect of the MPSF is de-epithelialized and used as interposition flap. RESULTS: The 3 patients with complex rectourethral fistulas were operated upon with the MPSF technique. After a median follow-up of 14 months all the patients are cured. CONCLUSIONS: The MPSF is a straightforward procedure that allows excellent access both to the bulbar urethra and to the surgical plane between rectum and prostate. It does not require a separate incision for the flap harvesting procedure in case it is necessary.

Post-circumcision penile skin loss: reporting the outcome of one-stage anterolateral scrotal based flaps in children

ABSTRACT Introduction Improper penile assessment, together with carrying out circumcision by an inexperienced person, results in major complications. One of the complex complications is the complete or sub-complete penile skin loss, which in many cases, necessitates one or staged repair. Purpose To evaluate modified one-stage bilateral anterolateral scrotal-based flaps to compensate for penile skin loss after circumcision. Methods This study was performed on patients with almost penile skin loss after circumcision from February 2013 to July 2021. In all cases, one-stage modified bilateral anterolateral scrotal skin flaps were used to compensate for penile skin loss. The modification includes scrotal skin flap fashioning in a novel way, in addition to the use of penodermal fixation sutures at the penoscrotal junction, to create a stable penoscrotal junction and new penile skin coverage. Patients were discharged from the hospital on the same day of surgery. The dressing was left for 5 days. Follow-up visits were scheduled weekly in the first month, 3 and 6 months later, then annually. Results Forty-six children were included in this study. Their mean age was 4.5 ± 1.5 years. The mean operative time was 139.6 ± 11.5 min. No flap ischemia or necrosis was reported. One case (2.2%) developed a scrotal hematoma managed conservatively. Three (6.5%) cases presented with wound dehiscence at the penoscrotal angle. Three (6.5%) cases had self-limited penile edema. Two (4.3%) cases had dorsal midline hypertrophic scar; one improved after treatment with triamcinolone acetonide ointment, and the other needed scar revision. The mean follows up was 23.33 ± 9.13 months. Conclusion The modified scrotal skin flap technique provides a good substitution for stable penile skin coverage and a one-stage reconstruction of penile skin loss. It results in good parents’ satisfaction with acceptable complications.

A New Modified Bipedicle Scrotal Skin Flap Technique for the Reconstruction of Penile Skin in Patients with Paraffin-Induced Sclerosing Lipogranuloma of the Penis.

We introduce a new modified penile skin reconstruction technique to treat paraffin-induced sclerosing lipogranuloma of the penis. From 2017 to 2020, 49 patients underwent the procedure. Complete removal of the lipogranuloma-involved penile skin was performed. A subcutaneous tunnel was then created between a horizontal scrotal incision and a proximal penile circumferential incision. The denuded penis was pulled through the tunnel, and a subcoronal and longitudinal dorsal penile suture line was made. An inverted V-shaped incision was made on the scrotum on the ventral side of the penis, followed by longitudinal closure. Outcomes and complications of the procedure were retrospectively studied. The long-term effect of surgery on sexual function and overall satisfaction was measured using a patient-reported questionnaire, which was completed by 30 patients. The overall complication rate was 26.5%. Clavien-Dindo grade 1, 2, 3a, 3b, 4 and 5 complications occurred in the postoperative period 5, 0, 8, 1, 0 and 0 times, respectively, in 13 patients. Surgery was successful in 27 (90%) patients according to the patient-reported questionnaire. Erectile dysfunction, pain/tension during erection, premature ejaculation and penile lymphedema were observed in 2, 3, 1 and 1 patients, respectively. All patients reported sexual intercourse ability. The type of penile skin reconstruction after the removal of sclerosing lipogranuloma of the penis is controversial. The reconstruction technique presented herein is an effective single-stage treatment option with a high success rate in patients with sclerosing lipogranuloma of the penis with intact scrotal skin.

Mathieu vs urethral plate tubularization in circumcised Megameatus intact prepuce repair: A prospective randomized comparative study.

The objective of this study is to evaluate and compare urethral plate tubularization vs Mathieu in circumcised Megameatus intact prepuce (MIP) repair. Many techniques were described for MIP, which account for 5% of hypospadias cases and usually diagnosed at time of, or even after circumcision. Forty-six circumcised MIP cases were prospectively enrolled in this prospective study, which was carried out in April 2017 and March 2020. Patients were randomly allocated into two groups. Group one operated by simple urethral plate tubularization and group two by the Mathieu technique. Hypospadias objective scoring evaluation (HOSE) scores, success rate, operative time, and the need for relaxing incision or scrotal flaps for skin closure were compared. Forty-three circumcised cases (22 in group one and 21 in group two) completed at least 6 months of follow-up. Ages ranged from 12 to 39 months (mean 18.06 6 6.35) in group one and from 10 to 32 months (mean 19.5 6 7.14) in group two. There was no significant difference between cases with accepted outcome based on HOSE scores (14) of the two groups (P value ¼ .942). Three fistulae and one meatal stenosis were the complications in group one (18.2%). In group two, two patients complicated with fistula (9.5%) (P value ¼ .674). Significant differences were present only in the operative time (P ¼ .001) and in the need of relaxing incision or scrotal skin flaps (P ¼ .012) both were more in group two. Mathieu and tubularized incised plate urethroplasty both are good options for circumcised MIP repair.

Staged penile skin reconstruction for sclerosing lipogranuloma

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. 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. 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. 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. 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.

The surgical treatment of male perineum Paget's disease

Objective: To evaluatethe clinical efficacy and complications of skin graft and flap plastic technique covered the defect in perineal Paget's disease postoperatively. Methods: The study comprised 6 patients diagnosed with perineal Paget's disease at Beijing Chao-Yang Hospital from June 2017 to July 2019, with all available clinical data reviewed. The defects after resection of lesions were reconstructed with skin graft, advancement skin flap during the operation, respectively. The operation time, the skin graft or flap survival situation, intraoperative and postoperative complications were recorded. Results: Of all 6 patients, Ray stage A1consisted of 1 case, A2 5 cases. The age was (68±9) years, the hospitalization time was (14.8±8.1) days, the BMI was (25.6±3.7) kg/m(2), the operation time was (132.0±80.7) min, and the average blood loss was (18.3±11.7) ml. Five cases was with Paget's disease, and 1 case with skin adenocarcinoma with Paget's disease were diagnosed by pathology. The defects of 4 cases and 2 cases after removal of the tumor were reconstructed with scrotal advancement skin flap and skin graft, respectively. The skin graft and flap survived well during afollow-up of (15.3±8.1) months.There has been no local recurrence. The foreskin edema and wound infection were noted in 4 cases and 1 case, respectively. There was no other related complications. Conclusion: Perineal Paget's disease can be managed by resection and immediate reconstruction with skin graft or flap according to the size and location of the defect, and the clinical efficacy is distinct.

Experiences with Surgical Reconstruction of Penoscrotal Extramammary Paget's Disease: A review of 21 cases

Penoscrotal extramammary Paget's disease is a rarely found intraepithelial adenocarcinoma in older male patients. The challenge for surgeons to perform high-quality post-surgery reconstruction is mostly case-dependent. Here, we present a review of post-surgical reconstruction practice in 21 cases using various scrotal skin flaps. During the 10-year study period (from 2008 to 2018), all 21 male patients diagnosed with penoscrotal extramammary Paget's diseases at Sun Yat-sen memorial hospital were enrolled in this study. All patients underwent expanding resections guided by frozen sections and penoscrotal reconstructions using various scrotal skin flaps alone or combined with pubic skin flaps and partial thickness skin graft depending on individual defects. The patient's clinical data, specifically the diagnosis, surgical outcome, and follow-up evaluation were retrospectively analyzed. The size of skin lesions ranged from 4 × 5 cm to 16 × 18 cm approximately. Out of 21 total cases, 13 patients received combined scrotal and pubic flaps, three patients received single scrotal flaps, and five patients received scrotal flaps and partial thickness skin grafts. Limited flap tip necrosis (two cases) and wound dehiscence (one case) were observed, and secondary resections were performed in four cases with positive post-operative pathological results. All patients experienced complete wound healing and had well-maintained penile morphology and function. Various scrotal skin flaps alone or combined with pubic skin flaps designed for individual lesion conditions in patients with penoscrotal extramammary Paget's disease are efficient for scrotal reconstruction. A good match of the local skin texture helps to maintain the morphology and function of the penis and scrotum.

Male-to-Female Gender-Affirming Surgery Using Nile Tilapia Fish Skin as a Biocompatible Graft

Insufficient penile skin is common during vaginoplasty for male-to-female transition. This issue may be compensated by a scrotal skin flap, with the drawback of hair growth [1]. In recent studies, Nile tilapia skin was successfully used for the surgical management of Mayer-Rokitansky-Küster-Hauser syndrome [2,3] and vaginal stenosis [4,5]. This study aims to describe a novel technique for primary vaginoplasty in male-to-female gender-affirming surgery using Nile tilapia skin as a biocompatible graft to ensure adequate vaginal depth. Stepwise demonstration of the procedure with narrated video footage. Transgender health clinic. A 29-year-old patient with gender dysphoria was referred to our office because of a desire for gender-affirming surgery. A physical examination revealed normal male genitalia with a 14-cm-long penis. Before surgery, approval from the institutional review board and written permission from the patient were obtained. After orchiectomy, penile disassembly, perineal dissection, and urethroplasty were performed, and a hollow Nile tilapia skin mold was prepared and sutured to the distal edge of the remaining penile skin. This structure was inverted, covering the newly created canal. The neocavity was then filled with a handmade inflatable vaginal mold, held in place by sutures in the labia majora. Finally, labiaplasty and clitoroplasty were conducted. After 7 days, the inflatable mold was removed, and the use of progressively larger dilators was initiated. After 3 weeks, a neovagina that was 16 cm long and able to accommodate the width of 2 fingers was detected. At that time, the Nile tilapia skin was completely reabsorbed into the neovaginal mucosa. There were no complications in the early postsurgical period. Nile tilapia skin, a safe, low-cost, and easy-to-use biocompatible material, may be an alternative option to scrotal skin grafts for neovaginal augmentation in primary vaginoplasty for male-to-female gender transition. However, further studies are needed to confirm this assertive.

Extensive Genital Warts in Man Hampering Conjugal Life: A Case Report

Genital warts, commonly known as condyloma acuminata, caused by the proliferation of squamous epithelial cells in the presence of sexually transmission of human papilloma Virus (HPV) infection. In human, HPV infection results in simple condyloma acuminatum, giant condyloma or Buschke-LÖwenstein tumour, and seldom penile carcinoma. There are several modalities of treatment options available for genital warts- medical and surgical, alone or in combination. Sometimes extensive genital warts represent a district entity resulting from HPV infection and require surgical management. We present the case of a 42-year-old male; rickshaw puller had multiple professional female sexual partners, who presented with extensive genital warts in penoscrotal region. Lesions were treated due to failure of medical management, by wide electrosurgical excision and rotation scrotal skin flaps

Complications after Self-injection of Chemical Substances into the Penis

Illicit injection of different, exogenous substances into the penis for enlargement purposes is a practice that is still met in some of the Eastern countries of Europe. Our study conducted over a period of 3 years (2016-2019) at the Urology Clinic from Tirgu Mures,highlights the complications that can occurre after the injection of different chemical substances, such as liquid paraffin, vaseline, olive oil etc., into the penile subcutaneous tissue with the purpose of augmentation. We report 7 patients presenting several complications some of them severe such as: extensive fibrosis, ulceration, penile deformity, erectile dysfunctions, requiring different surgical procedures. The surgical technique was selected according to the extension of fibrosis or necrosis:excision of the necrotic, fibrotic tissue, scrotal skin flap reconstruction etc. In our study, we found 7 patients that accomplished the inclusion criteria. Five patients were diagnosed with penile fibrosis after self-injection of Kanamycin, and two of the patients had the same diagnosis after self-injection of Vaseline. In 2 patients, the postoperative outcome was complicated by wound dehiscence and necrosis, requiring other reconstructive surgeries, and in 5 patients postoperative recovery was a favorable one, without significant complications. In the management of complications of illicit injection of different, exogenous substances into the penis, penile tunneling with scrotal flap technique seems to offer good results due to the vascular flap, allowing faster wound healing and a superior aesthetic and functional result.

Successful Reconstruction of the Penile Skin Loss Using a Scrotal Flap as a Result of Complete Resection Following a Traditional Circumcision: A Case Report

Background: Circumcision is the oldest and most common surgical procedure in the world. One out of three adult males is subjected to this procedure at some point in their lives. Circumcision is done for different reasons, most often to meet religious and/or cultural obligations. Though rare, there exist medical indications for this procedure. As in all surgical procedures, there are early or late complications or morbidities associated with circumcision ranging from mild to severe. The factors that influence the rate of occurrence of complications include: the surgical technique applied, the degree of asepsis during the procedure, and the expertise of the practitioner carrying out the procedure. Case Presentation: This is the case of a 20-year-old black male. He presented in the emergency department of the Douala Laquintinie Hospital (DLH) two hours after circumcision with persistent bleeding from the penile wound. This was performed by a traditional healer using the technique of guillotine. Examination of the external genitalia revealed a wound on the penis with loss of skin over the whole penile shaft. Under spinal anesthesia, a reconstruction intervention which involved a single step scrotal skin flap advancement over the penile shaft was done. We noted satisfactory healing process with a pleasing aesthetic appearance of the penis. He confirmed satisfactory penile erection and sexual activity two months after hospital discharge. Conclusion: Circumcision is a simple surgical procedure that can result to life threatening complications or high morbidity more often when performed by an unskilled practitioner. Education of the population on the safer sites of circumcision can help in the prevention and early management of complications.

Surgical Techniques for Correction of Penile Paraffinoma.

BackgroundPenile augmentation using injection of a foreign body into penile skin was mainly performed by non-medical personnel. Majority of these patients end up with complication of an abnormal mass formation known as penile paraffinoma.MethodsWe described three different surgical techniques for correction of penile paraffinoma based on our single-centre experience. Informed consents were obtained from patients whose photographs were taken during the operation step.ResultsIn general, three patients had simple excision biopsy with primary suturing, four patients underwent single stage excision of circumferential granuloma with bilateral scrotal skin flap reconstruction and one patient experienced dual stage procedure. Three of them were injected with paraffin, one with silicone and the remaining four were unable to identify the substance used. All patients successfully underwent the surgical procedure and four of them had minor post-operative surgical site infection and wound gapping.ConclusionAll patients recovered well and the mean International Index of Erectile Function (IIEF-5) score obtained was 24.25. In our experience, excision biopsy was adequate for focal mass and reconstructive surgery using bilateral scrotal flap was suitable for circumferential mass.

Surgical selection and outcome for treating the post-traumatic posterior urethral strictures via transperineal approach

Objective To evaluate the outcome of various operative selection for treating posterior urethral stricture via transperineal approach. Methods The clinical data of 5 000 patients with posterior urethral stricture or obstruction from January 1990 to January 2017 were analyzed retrospectively. All patients were male. The age of those patients ranged from 18 months to 77 years old, mean 36.6 years old. Pelvic crush injury caused by car accident occurred in 2010 cases. Falling injury occurred in 1680 cases. Pelvic compressed injury occurred in 1 310 cases. Accompanied visceral damage occurred in 2 590 cases, including the liver and spleen rupture in 920 cases, lower limb fracture in 1 200 cases. 2 200 cases accepted urethral realignment under emergency. 2 800 cases were treated with pubic cystostomy. All patients were undergone a retrograde and voiding urethrogram. 562 patients accepted urethral ultrasongraphy, and 2 448 patients accepted urethroscopy. 204 patients accepted MRI examination. The mean stricture length was 4.3 cm, ranged from 1.8 to 8.6 cm. Posterior urethral stricture was found in 810(16.2%)cases. The complete obstruction of posterior urethra was found in 4 190(83.8%)cases, of which the length of the distraction defects≤3 cm was found in 2 650(53.0%)cases and the length of the distraction defects>3 cm was found in 1 540(30.8%)cases. Bladder calculi was found in 2 300 cases. The perineal fistula or abscess was noticed in 290 cases. False passage was found in 460 cases. Urethra rectum fistula was found in 160 cases. Bladder neck open was noticed in 89 cases. Repairing was performed via a simple anastomosis after urethral mobilization in 1 700 patients, via separation of the corporeal bodies in 1 302 patients, via separation of the corporeal bodies and inferior pubectomy in 1 910 patients and via scrotal skin flap urethroplasty in 68 patients. Pull-through operation was performed in 20 patients. Results Postoperative follow-up were conducted from 6 to 72 months with average duration of 23 months. The overall successive results after operation was 92.2%(4 608/5 000), which the Qmax was more than 15 ml/s .The successive rate of urethroplasty were 97%(1 649/1 700 )in simple anastomosis; 93%(1 211/1 302 )in separation of the corporeal bodies; 88% (1 680/1 910) in separation of the corporeal bodies and inferior puberctomy; 78%(53/68) in scrotal skin flap urethroplasty and 83%(15/18) in pull-through operation. The successive rate were 96%(778/810)in posterior urethral stricture; 95%(2 517/2 650)in distraction with the length of obstruction less than 3 cm and 86%(1 324/1 540)in distraction with the length of obstruction more than 3 cm. Conclusions The transperineal end to end anastomotic urethroplasty has become the first-line therapy for posterior urethral atresia. The length of the strictures or distraction defect which is lower than 3 cm is much more successfully corrected.

A novel application of the lotus petal flap in high-risk perineal urethrostomy: principles and outcomes

Introduction: Perineal urethrostomy is a valuable technique in the management of complex anterior urethral strictures, as well as following penectomy or urethrectomy. Traditional techniques that employ perineal or scrotal skin flaps have documented failure rates of up to 30 per cent. Current techniques for salvage have only modest success, leaving patients few options other than permanent suprapubic catheter or cystectomy and ileal conduit formation. Results: We present a new method of perineal urethrostomy using perforator-based lotus petal flaps in cases which were high risk or unsuitable for traditional perineal urethrostomy techniques, or where traditional strategies had failed. All patients demonstrated continent voiding at a minimum of 22 months follow-up, with patency confirmed by flexible cystoscopy. No complications were encountered.**Conclusion**: Utilisation of lotus petal flaps in high-risk cases of perineal urethrostomy will lead to significant improvements in patient outcomes. The availability of larger amounts of soft tissue coverage will obviate the need for compromise on either resection of involved urethra, or calibre and inset of urethrostomy. This will subsequently minimise the rates of failure, reduce the requirement for urinary diversion procedures and lead to improved quality of life.

Aesthetic criteria in surgical treatment of hypospadias in children

From 2013 to 2015, 476 patients with various forms of hypospadias were treated at the Department of Uroandrology of RCCH. The patients age ranged from 1 year to 17 years (mean age 3 years). All patients were divided into 3 groups depending on the form of hypospadias and type of treatment. They included patients with distal forms of hypospadias (group1, n=270), proximal forms (group 2, n=112) and patients with stem and penoscrotal hypospadias who underwent 3-6 operations before admission (group 3, n=94). The study evaluated both functional and cosmetic results. Cosmetic appearance was assessed using the HOPE scoring system [2]. Despite the difference in surgical methods used for all types of hypospadias, good cosmetic results have been achieved in the majority of patients (65%). Functional outcomes differed depending on the form of hypospadias. In primary patients with distal and proximal forms of hypospadias, good results were achieved in 96% and 77% of patients, respectively. At the same time, 72% of patients who underwent repeat interventions had good results, which is comparable to the group of primary patients with proximal forms. The results of treating patients after repeat/failed surgery confirm the high effectiveness of our surgical methods (the Bracka two-stage graft repair, buccal mucosa hypospadias repair, reconstruction with scrotal skin flaps, correction of scrotal transposition). Using the HOPE scoring system to assess cosmetic results helps motivate surgeons to achieve the best treatment results.

Utilities of scrotal flap for reconstruction of penile skin defects after severe burn injury.

In the present study, we aimed to present our experience of an effective two-stage surgical approach using scrotal skin flap for patients with penile skin defects following severe burn injury. A total of 17 patients with penile skin defects underwent scheduled two-stage reconstruction using scrotal skin flap from January 2004 to October 2016. Patients, who were selected as eligible candidates for scrotal flap, exhibited a wide range of indications, including iatrogenic injuries (e.g., diathermy treatment after circumcision), scalding, flame injuries and electrical burns. During the first stage, the denuded penis secondary to debridement was temporally embedded in scrotal skin flap through an intrascrotal tunnel created between the skin and darto's fascia. During the second stage, the skin around the penis was separated and divided from the scrotum after incising the scrotal skin at the ventral penile base. After a mean follow-up of 30months, the reconstructedpenisesyielded satisfactoryaesthetic outcomes and maintained erectile function. The mean age of patients was 35years (19-55years), and the median follow-up was 30months (12-60months). No major perioperative complication occurred except for dehiscence of scrotal skin after 2nd stage in three patients, and split-thickness skin grafts were applied for recovery of scrotum. Of 17 cases, 15 patients (88.2%) were in satisfactory cosmetic appearance. All patients regained penile sensation and normal voiding function in standing position. The International Index of Erectile Function (IIEF) was used to assess sexual function, with 13 patients (76.5%) reported normal erectile function, while the rest 4 reported mild erectile dysfunction. With regards to intercourse satisfaction domain, encouraging results indicated a total of 17 patients resumed sexual intercourse after surgery. In overall satisfaction domain, 11/17 (64.7%) reported a satisfaction from "very" to "moderately" with their overall sex life and sexual relationship with their partners, while only one patient reported "moderately dissatisfied" with his overall sex life. We report a series of particular cases, including rare iatrogenic injury (diathermy treatment after circumcision) and severe compound electrical injury. Meanwhile, we show our successful experience that scrotal skin flap could be used as an effective surgical alternative to cover severe burn injury wound in male genitalia. The scrotal flap, with higher anti-infection ability and flexible contexture, is available for recovering penile skin defects following severe burn injury resulting in good aesthetic and sexual outcomes.

Resurfacing the Penis of Complex Hypospadias Repair (“Hypospadias Cripples”)

After the creation of a neourethra in a "hypospadias cripple," resurfacing the penis with healthy skin is a significant challenge because local tissue is often scarred and unusable. We reviewed our experience with various strategies to resurface the penis of hypospadias cripples. We retrospectively reviewed the records of 215 patients referred after multiple unsuccessful hypospadias repairs from 1981 to 2014. In 130 of 215 patients we performed resurfacing using local penile flaps using various techniques, including Byars flaps, Z-plasty or double Z-plasty, or a dorsal relaxing incision. Of the 215 patients 85 did not have adequate healthy local penile skin to resurface the penis after urethroplasty. Scrotal skin was used to resurface the penis in 54 patients, 6 underwent tissue expansion of the dorsal penile skin during a 12 to 16-week period prior to penile resurfacing, 23 underwent full-thickness skin grafting and another 4 received a split-thickness skin graft. Of the 56 patients who underwent fasciomyocutaneous rotational flaps, tissue expansion or a combination of both approaches 54 (96.4%) finally had a successful outcome. All 6 patients who underwent tissue expansion had a successful outcome without complications and were reported on previously. All 23 full-thickness skin grafts took with excellent results. All 4 patients who underwent fenestrated split-thickness skin grafting had 100% graft take but secondary contraction and ulceration were associated with sexual activity. In our experience scrotal skin flaps, tissue expansion of the dorsal penile skin and full-thickness skin grafts serve as reliable approaches in resurfacing the penis in almost any hypospadias cripple lacking healthy local skin.

Orandi flap for penile urethral stricture: Polishing the gold standard.

We describe the combined use of the Orandi flap and the scrotal skin advancement flap to reduce complications for pendulous urethral stricture in men >40 years old. Over the last 40 months, 10 men underwent urethroplasty for pendulous stricture by the modified Orandi urethroplasty. In this, additionally, a midline hairless scrotal skin flap of the size of the ventral skin defect on the pendulous portion was raised based on the dartos fascia. This flap was mobilized so that it reached the pendulous portion without tension and covered the penile defect. The catheter was removed after 4 weeks. Patients were followed every 3 months using uroflowmetry and the American Urological Association (AUA) symptom score. The mean age was 55.5. Of the 10 patients, the etiology was post-catheterization in 5 and idiopathic in the remaining 5. Three men also had stricture extending into the bulbous urethra (repaired using buccal graft). The mean additional time needed for the flap coverage was 36.2 minutes (range: 30-45). The median follow-up was 12 months (range: 3-40). The mean postoperative symptom score was 5.2 and the mean flow rate was 20.1 mL/sec. In 2 men, the meatus got retracted to the distal penile part (probably due to downward traction by scrotal skin). No patient complained of disfigurement. Two men reported recurrence (1 each in bulbous and penile urethra). The limitations are small number of patients and the observational nature of this study. The intermediate-term results show that the modified Orandi urethroplasty is an acceptable treatment option with acceptable cosmetic results.

Ventral Slit Scrotal Flap: A New Outpatient Surgical Option for Reconstruction of Adult Buried Penis Syndrome

We present a novel technique using ventral slit with scrotal skin flaps (VSSF) for the reconstruction of adult buried penis without skin grafting. An initial ventral slit is made in the phimotic ring, and the penis is exposed. To cover the defect in the ventral shaft skin, local flaps are created by making a ventral midline scrotal incision with horizontal relaxing incisions. The scrotal flaps are rotated to resurface the ventral shaft. Clinical data analyzed included preoperative diagnoses, length of stay, blood loss, and operative outcomes. Complications were also recorded. Fifteen consecutive patients with a penis trapped due to lichen sclerosus (LS) or phimosis underwent repair with VSSF. Each was treated in the outpatient setting with no perioperative complications. Mean age was 51 years (range, 26-75 years), and mean body mass index was 42.6 kg/m(2) (range, 29.8-53.9 kg/m(2)). The majority of patients (13 of 15, 87%) had a pathologic diagnosis of LS. Mean estimated blood loss was 57 cc (range, 25-200 cc), mean operative time was 83 minutes (range, 35-145 minutes), and all patients were discharged on the day of surgery. The majority of patients (11 of 15, 73.3%) remain satisfied with their results and have required no further intervention. Recurrences in 3 of 15 (20.0%) were due to LS, panniculus migration, and concealment by edematous groin tissue; 2 of these patients underwent subsequent successful skin grafting. VSSF is a versatile, safe, and effective reconstructive option in appropriately selected patients with buried penis, which enables reconstruction of penile shaft skin defects without requiring complex skin grafting.
