INTRODUCTION There are several techniques for creation of a neovagina. However, rectosigmoid segment presents the most natural substitute for vaginal tissue. AIM To evaluate the anatomical and functional results of sigmoid vaginoplasty and long-term sexual and psychological outcomes in 86 patients with vaginal absence. METHODS Between April 2000 and February 2009, 86 patients, aged 18 to 57 years (mean 22) underwent rectosigmoid vaginoplasty. Indications were vaginal agenesis (54), female transgenderism (27), and genital trauma (5). Rectosigmoid segments ranging from 8 cm to 11 cm were isolated, to avoid excessive mucus production. Preferably, it should be dissected distally first in order to check its mobility and determine the correct site for its proximal dissection. Stapling device was used for the colorectal anastomosis as the safest procedure. Creation of perineal cavity for vaginal replacement was performed using a simultaneous approach through the abdomen and perineum. Perineal skin flaps were designed for anastomosis with rectosigmoid vagina for the prevention of postoperative introital stenosis. Main Outcome Measures. Sexual and psychosocial outcomes assessment was based on the Female Sexual Function Index, Beck Depression Inventory, and standardized questionnaires. RESULTS Follow-up ranged from 8 to 114 months (mean 47 months). Good aesthetic result was achieved in 77 cases. Neovaginal prolapse (7) and deformity of the introitus (9) were repaired by minor surgery. There was no excessive mucus production, vaginal pain, or diversion colitis. Satisfactory sexual and psychosocial outcome was achieved in 69 patients (80.23%). CONCLUSIONS Rectosigmoid colon presents a good choice for vaginoplasty. According to our results, sexual function and psychosocial status of patients who underwent rectosigmoid vaginoplasty were not affected in general, and patients attained complete recovery.

INTRODUCTION Metoidioplasty presents one of the variants of phalloplasty in female transsexuals. Urethral lengthening is the most difficult part in this surgery and poses many challenges. AIM We evaluated 207 patients who underwent metoidioplasty, aiming to compare two different surgical techniques of urethral lengthening, postoperative results, and complications. METHODS The study encompassed a total of 207 patients, aged from 18 to 62 years, who underwent single stage metoidioplasty between September 2002 and July 2011. The procedure included lengthening and straightening of the clitoris, urethral reconstruction, and scrotoplasty with implantation of testicular prostheses. Buccal mucosa graft was used in all cases for dorsal urethral plate formation and joined with one of the two different flaps: I-longitudinal dorsal clitoral skin flap (49 patients) and II-labia minora flap (158 patients). MAIN OUTCOME MEASUREMENT Results were analyzed using Z-test to evaluate the statistical difference between the two approaches. Also, postoperative questionnaire was used, which included questions on functioning and esthetical appearance of participating subjects as well as overall satisfaction. RESULTS The median follow-up was 39 months (ranged 12-116 months). The total length of reconstructed urethra was measured during surgery in both groups. It ranged from 9.1 to 12.3 cm (median 9.5) in group I and from 9.4 to 14.2 cm (median 10.8) in group II. Voiding while standing was significantly better in group II (93%) than in group I (87.82%) (P < 0.05). Urethral fistula occurred in 16 patients in both groups (7.72%). There was statistically significant difference between the groups, with lower incidence in group II (5.69%) vs. group I (14.30%) (P < 0.05). Overall satisfaction was noted in 193 patients. CONCLUSION Comparison of the two methods for urethral lengthening confirmed combined buccal mucosa graft and labia minora flap as a method of choice for urethroplasty in metoidioplasty, minimizing postoperative complications.

OBJECTIVES Urethral reconstruction in severe hypospadias presents a great challenge. We have designed a method of combining a longitudinal dorsal island skin flap and buccal mucosa graft to create a neourethra in most severe hypospadias. METHODS Between January 2003 and March 2007, 17 patients (aged from 9 to 23 months) underwent severe hypospadias repair (13 penoscrotal and 4 scrotal hypospadias). Short urethral plate was divided in all cases and remaining curvature repaired by dorsal plication. We harvested and fixed a buccal mucosa graft to the ventral side of corpora cavernosa to be the first half of a neourethra. A longitudinal dorsal island skin flap was created and buttonholed ventrally. We sutured it together with the buccal mucosa graft to form the neourethra. We fixed the abundant flap pedicle laterally to cover all suture lines of the neourethra. We performed penile skin reconstruction using available penile skin. RESULTS The mean (range) follow-up was 25 (7 to 58) months. We achieved satisfactory, functional, and aesthetic results in 14 patients. In 3 cases urethral fistula (2) and distal stricture (1) required secondary treatment. CONCLUSIONS Combined longitudinal island skin flap and buccal mucosa graft could be a good choice for urethral reconstruction in most severe hypospadias repairs.

OBJECTIVES To develop a technique for urethral reconstruction using a combined labia minora flap and buccal mucosa graft. Urethral lengthening is the most difficult part in female transsexuals and poses many challenges. METHODS From April 2005 to February 2008, 38 patients (aged 19-53 years) underwent single-stage metoidioplasty. The technique starts with clitoral lengthening and straightening by division of both clitoral ligaments dorsally and the short urethral plate ventrally. The buccal mucosa graft is quilted to the ventral side of the corpora cavernosa between the native orifice and the tip of the glans. The labia minora flap is dissected from its inner surface to form the ventral aspect of the neourethra. All suture lines are covered by the well-vascularized subcutaneous tissue originating from the labia minora. The labia majora are joined in the midline and 2 silicone testicular implants are inserted to create the scrotum. The neophallus is covered with the remaining clitoral and labial skin. RESULTS The median follow-up was 22 months (range 11-42). The median neophallic length was 5.6 cm (range 4-9.2). The total length of the neourethra was 9.4-14.2 cm (median 10.8). Voiding while standing was reported by all 38 patients, and temporary dribbling and spraying were noted by 12. Two fistulas and one urethral erosion resulted from the testicular implant and required secondary revision. CONCLUSIONS A combined buccal mucosa graft and labia minora flap present a good choice for urethral reconstruction in female-to-male transsexuals, with minimal postoperative complications.

BACKGROUND The main goal in women with Mayer-Rokitansky-Küster-Hauser syndrome (vaginal agenesis) is creation of a neovagina that will satisfy the patients desire. We evaluated sexual and psychosocial adjustment in patients who underwent rectosigmoid vaginoplasty because of vaginal agenesis. METHODS A total of 36 women, aged 21 to 38 years (mean=26) who underwent rectosigmoid vaginoplasty from 1997 to 2006 were evaluated. Sexual and psychosocial appraisal included the Female Sexual Function Index (FSFI), Becks Depression Inventory (BDI), and standardised questionnaires about postoperative satisfaction, social and sexual adjustment. RESULTS Mean FSFI score was 28.9 (range=11.5-35.7) with a cut-off score of 26.55 for sexual dysfunction. Out of the 36 women, 10 (27, 8%) had sexual dysfunction. Mean BDI score was 7.55 (cut-off score=0-9 for non-depression). Twenty-eight women (77.8%) were without symptoms of depression, six women (BDI range=10-29) had moderate and two women had severe depression (BDI=42). There were a significant number of patients (P<0.01) with a high satisfaction score in FSFI and low BDI results. Thirty-two (88.9%) of the patients believed that surgery was done at the right time and the main postoperative support came from their family. Thirty-four (94.4%) of the patients reported satisfactory femininity, with a heterosexual orientation. Thirty patients (83. 3%) were very satisfied with the surgery, while 34 considered surgery as the best treatment. CONCLUSIONS The sexual function and psychosocial status of these patients should be followed long-term to estimate their quality of life.

Transsexualism is a complex condition in which the person experiences the inconsistency between the desired gender and their biological gender. Absence of the vagina is devastating in male to female transsexuals. Creation of the neovagina is the main surgical problem in these patients. Historically, beginnings of the neovaginal creation have their roots in the treatment of Mayer-Rokitansky syndrome and conditions such as cloacal anomalies, certain intersex disorders, vaginal malignancies, or severe vaginal trauma, but have more recently found great purpose in male to female sex reassignment surgery. Many operative procedures have been described but none is ideal. Therefore, the search for new, improved solutions continues. In neovaginoplasty reconstruction of the vulvovaginal complex is performed in its entity. The gold standard in neovaginal reconstruction in male to female sex reassignment surgery is penile skin inversion technique with or without scrotal flaps, which enables adequate sensation of the neovagina, good neovaginal depth, good erotic sensitivity of the neclitoris, and esthetically acceptable labia minora and maiora.

PURPOSE Urethral stricture is the second most common complication of hypospadias repair after urethrocutaneous fistula. Usually more than 1 procedure is needed for correction due to a lack of available tissue after previous repairs. We evaluated 1-stage urethral stricture management after hypospadias repair using a ventral buccal mucosal graft. We describe the importance of graft hanging and coverage. MATERIALS AND METHODS From August 2004 to April 2009, 15 patients 9 to 17 years old underwent urethral stricture repair after failed hypospadias surgery. Mean time after primary surgery was 7.2 years (range 4 to 13). Vascularized periurethral tissue around the stenotic part of the neourethra was dissected. The urethra was opened ventrally and a buccal mucosal graft of appropriate size was inserted to allow urethral augmentation. Using several U stitches the graft was anchored to the surrounding periurethral tissue to prevent its folding and retraction. Recurrent chordee in 12 patients and secondary vesicoureteral reflux in 3 were also corrected at this time. RESULTS Mean followup was 37 months (range 17 to 73). Successful results were confirmed in all patients by urethrography and uroflowmetry. One urethral fistula was corrected 3 months later by minor surgery. Recurvature did not develop in this group. There was no recurrent reflux in endoscopically treated patients. CONCLUSIONS Ventral buccal mucosal grafting is a simple, safe option for urethral stricture repair. Hanging the graft to periurethral tissue is important for its survival and to prevent postoperative folding and retraction.

OBJECTIVE To review our experience with severe penile trauma, mechanism of injury, and their treatment modalities in 16 children younger than 18 years. Management of penile trauma poses diverse challenges to the reconstructive urologist, as injuries vary from abrasions to total emasculation. METHODS Analysis of 16 patients with severe penile injuries referred to us between 2002 and 2011 was undertaken. The median age at surgery was 13 years (range, 5-17). Etiology of penile trauma and choice of treatment were evaluated. The management included a wide variety of surgical techniques that were tailored to the individual patient. Results were analyzed to define etiology, that is, mechanism of penile injury and to estimate modalities of surgical management and postoperative outcomes. Also, postoperative questionnaire was used, which included questions on functioning and esthetical appearance of participating patients and overall satisfaction. RESULTS The causes of penile injury in these series were traffic accidents (2), iatrogenic trauma (5), self-amputation (1), electrocution (1), burns (3), dog bite (2), zipper injury (1), and mothers hair strangulation (1). The mean follow-up was 46 months (range, 14-122), and examinations were uneventful, except for 2 fistulae formation after neophallic urethral reconstruction. CONCLUSION The main goal of reconstructive surgery is to have a penis with normal appearance and functions. Severe penile injuries should be treated on a case-by-case basis using the most propitious techniques.

Background. Investigations in the field of gender identity disorder (GID) have been mostly related to psychiatric comorbidity and severe psychiatric disorders, but have focused less on personality and personality disorders (PDs). Aims. The aim of the study was to assess the presence of PDs in persons with GID as compared to cisgendered (a cisgender person is a person who is content to remain the gender they were assigned at birth) heterosexuals, as well as to biological sex. Methods. The study sample consisted of 30 persons with GID and 30 cisgendered heterosexuals from the general population. The assessment of PDs was conducted by application of the self-administered Structured Clinical Interview for DSM-IV Axis II PDs (SCID-II). Results. Persons with GID compared to cisgender heterosexuals have higher presence of PDs, particularly Paranoid PD, avoidant PDs, and comorbid PDs. In addition, MtF (transwomen are people assigned male at birth who identify as women) persons are characterized by a more severe psychopathological profile. Conclusions. Assessment of PDs in persons with GID is of great importance as it comprises a key part of personalized treatment plan tailoring, as well as a prognostic factor for sex-reassignment surgery (SRS) outcome.

AIM OF THE STUDY Urethral reconstruction in severe hypospadias presents a great challenge. We evaluated a method of combining longitudinal dorsal island skin flap and buccal mucosa graft to create a neourethra in the most severe hypospadias. Our aim was to repair the most difficult cases in a one-stage procedure. METHODS Between January 2003 and July 2007, 23 patients (aged from 9 to 26 months) underwent repair of severe hypospadias (18 penoscrotal and 5 scrotal forms). The short urethral plate is divided in all cases and the remaining curvature was repaired by dorsal plication. The buccal mucosa graft is harvested and fixed to the ventral side of corpora cavernosa to form the first half of the neourethra. A longitudinal dorsal island skin flap is created and buttonholed ventrally. It is sutured to the buccal mucosa graft to form the neourethra. An abundant flap pedicle is fixed laterally to cover all the suture lines of the neourethra. Penile skin reconstruction is done using available penile skin. RESULTS The mean follow-up was 27 (range 11-66) months. Satisfactory results were achieved in 20 patients. There were two urethral fistula and one temporary distal urethral stricture. CONCLUSION A combined longitudinal island skin flap and buccal mucosa graft could be a good choice for single-stage urethral reconstruction in the repair of the most severe hypospadias.
