Abstract
OBJECTIVES We report our experience with urethral reconstruction for hypospadias surgery-related urethral stricture in terms of surgical and patient-reported outcomes. METHODS Twenty-nine adult males who underwent urethral reconstruction for hypospadias surgery-related urethral stricture between August 2008 and January 2022 were retrospectively reviewed. Uroflowmetry and patient-reported outcomes were evaluated at 3, 6, and 12 months, and annually thereafter. Surgical success was defined as the absence of additional procedures. Patients were asked to rate their satisfaction with urethral reconstruction as "very satisfied", "satisfied", "unsatisfied", or "very unsatisfied". RESULTS The median patient age at referral was 43 years. The median number of previously performed hypospadias surgeries was three, and 18 patients (62.8%) had been treated with repeated transurethral procedures. The median stricture length was 54 mm (interquartile range 36-81). Performed urethral reconstruction included staged urethroplasty in 22 (75.9%), one-stage onlay augmentation in 3 (10.2%), and perineal urethrostomy in 4 (13.8%) cases. Urethral reconstruction was successful in 26 patients (89.7%) over a median postoperative period of 31 months. Patient-reported outcomes were assessed in 25 (86.2%) patients. The mean maximum flow rate, international prostate symptom score total score, international prostate symptom score quality of life score, and EuroQol-5 dimensions index significantly improved postoperatively. Twenty-three patients (92%) were "very satisfied" or "satisfied" with the outcome of their urethral reconstruction. CONCLUSIONS Urethral reconstruction is a highly successful and patient-satisfying treatment for hypospadias surgery-related urethral stricture in adult patients. Perineal urethrostomy is a reasonable alternative for elderly patients and for patients with complicated hypospadias surgery-related urethral strictures.

Abstract
Background Chordee correction, urethroplasty, and tissue reconstruction are performed to correct and retain standard functionality of the penis in hypospadias. Conventional reconstruction techniques, such as onlay island flap and the dorsal inlay graft, can be performed based on the classification of hypospadias. However, the outcomes and complication rates have not been widely studied. Thus, we aimed to provide preliminary evidence regarding the efficacy and safety of both approaches in hypospadias reconstruction. Patients and Methods A prospective study with two time evaluations of 14 and 180 days post-operatively was performed at the Urology outpatient clinic from October 2014 to September 2019. A proportion comparison of success rate, time to the complication, operation time, catheterization duration, uroflowmetry parameter post-surgery, and mean scores comparison of PPPS were measured as the intended outcomes. Results In a total of 59 pediatric hypospadias, patients who had undergone reconstruction are included in this study. Higher subjects’ age and severe chordee severity were more common in the dorsal inlay graft group (age=7.50 [1–26] months; severe chordee 45.8%) compared to the onlay island flap group (age=4.0 [1–67] months; severe chordee 31.4%), both groups showed similar satisfaction regarding meatal shape and position (P=0.618), glands shape (P=0.324), penile skin shape (P=0.489), and general cosmetic appearance (P=0.526). Complication occurrence and time to complication duration of both groups were also not statistically significant (P=0.464 and P=0.413). There are no significant differences in Qmax, Qmean, voided volume, and PVR of both groups (P=0.125, 0.136, 0.076, 0.260, respectively). Significant differences in operation times and catheterization duration are found in this study (P<0001). Conclusion Outcome evaluation regarding functional, complication and patient satisfaction comparing onlay flap and dorsal inlay graft for hypospadias patients is scarce. This study found that both procedures can be considered safe with comparable incidence of complications.

Abstract
INTRODUCTION Proximal hypospadias associated with severe chordee represents a major surgical challenge and the debate over its optimal treatment is ongoing. The objective of this study is to compare the outcome of two-stage Bracka and Byar's repair in proximal hypospadias. MATERIALS AND METHODS This study was conducted from January 2013 to February 2018 in a tertiary care centre. Patients of hypospadias with severe chordee who required urethral plate transection were included in the study. Patients were randomly divided into two groups by simple randomization method. Bracka staged repair was done in Group A and Byar's staged repair in Group B. Postoperatively complications including graft loss, flap necrosis, fistula formation, meatal stenosis, stricture, diverticula formation, residual chordee were noted in both the groups and compared. p value of < 0.05 was considered statistically significant. RESULTS Over a period of 5 years, 74 patients in group A and 68 patients in group B were operated. Fistula occurred in 6.8% and 10.2% in group A and group B, respectively (p value 0.629). Meatal stenosis was seen in 4% in group A and 3% in group B (p value 0.731). Stricture was seen in 1% in each group (p value 0.339). Diverticula formation was seen in 2% in group B and none of the patient in group A (p value 0.960). None of the patient had recurrence of chordee in either group. CONCLUSION Bracka and Byar's two-stage repair have similar postoperative outcome and the choice between the two depends up on the surgeon's choice and experience rather than scientific evidence.

Abstract
Patients affected by a urethral stricture account for a considerable cost to all healthcare systems. The estimated prevalence of all urethral stricture in the UK is 10/100,000 men during youth, increasing to about 40/100,000 by age 65 years and to more than 100/100,000 thereafter. A penile urethral stricture is a narrowing of the lumen of the urethra due to ischaemic fibrosis of the urethral epithelium and/or spongiofibrosis of the corpus spongiosum occurring within the penile urethra. Its aetiology is largely idiopathic but other important causes are failed hypospadias repair and lichen sclerosus, which account for 60% of all cases. Strictures of the anterior urethra account for 92% of cases: bulbar strictures are more frequent (46.9%), followed by penile (30.5%) and combined bulbar/penile (9.9%), that is, 40.4% of all men presenting with stricture will have a penile urethral stricture alone or in combination with a bulbar urethral stricture. There are several options for the treatment of penile urethral strictures ranging from less invasive treatments, including urethral dilatation and direct vision internal urethrotomy, to more complex augmentation graft and flap urethroplasty. The aim of the present review is to describe the aetiology and epidemiology of anterior urethral strictures and the available options reported in literature for their treatment. Level of evidence: 1a

Abstract
PURPOSE The use of flaps in the two-stage repair of posterior hypospadias associated with severe chordee has been well established. Despite the almost certain guarantee of flap take, complications such as diverticuli are still relatively high. While different applications of the tubularized incised plate have been described, experience with the application of the technique to the two-stage flap repair is very limited. A previous local review of 15 cases performed at the present institution during the period 1998-2003, using the technique as described by Rekit, revealed fistulae and diverticulum rates of 20% and 27%, respectively. With the primary objective of improving surgical outcome, the midline incision was incorporated into the two-stage flap repair. MATERIALS AND METHODS Between 2004 and 2015, 35 boys (aged 2-15 years) with severe hypospadias that required excision of the urethral plate were operated using the two-stage flap technique. The first stage involved mobilization of preputeal or dorsal penile skin (if circumcised) to the ventral surface, as described by Retik. After a minimum interval of 6 months, the second-stage operation was performed in a way similar to the technique of tubularized incised plate urethroplasty, as popularized by Snodgrass, and involved a preliminary midline incision on the neo-urethral plate followed by tubularization and multilayered closure. RESULTS All but one flap took successfully. The outcome was satisfactory in 80% of patients, and there was a fistula rate of 14% ( Summary Table). One patient had a complete breakdown of the flap and was successfully treated about 12 months later by repeating the second stage of the operation. No case of diverticulum or stricture was recorded. DISCUSSION Even though there was a marginal improvement in the fistula rate, the most striking observation was the complete absence of diverticulum or stricture. With a reported incidence rate of 20-63%, different authors have reported diverticulum formation (despite the absence of distal obstruction) to be a major problem of the two-stage flap technique. Attempts by these authors at reducing the risk of diverticulum by reducing flap size have tended to increase the risk of strictures. This has been the main reason given by some authors for abandoning the technique. The main limitations of the present study included the wide age range of the patients and the small sample size. CONCLUSION The inclusion of a midline incision in a two-stage flap urethroplasty for proximal hypospadias appears to prevent the development of diverticulum.

Abstract
INTRODUCTION To investigate a modified transverse preputial island flap repair which is performed in an attempt to reduce the complications following one-stage repair of proximal hypospadias with chordee. METHODS Briefly, the two ends of the flap were trimmed into V shape and anastomosed with the spatulated urethra proximally and urethral plate distally before tubularization. Then the in situ tubularization of the flap was performed. The procedure was performed in our hospital on 32 patients (mean age = 11 months). They were followed for 12-38 months. RESULTS The length of the urethral defect ranged from 4.0-6.0 cm after chordee correction. Urethrocutaneous fistulae occurred in 6 (18.7%) cases. No urethral strictures or meatal stenoses were observed. 29/32 families were satisfied with the cosmetic results. CONCLUSION This procedure seems straightforward and reliable, leading to good result after a short-term follow-up.

Abstract
This review summarizes data regarding commonly used surgical techniques to repair distal and proximal hypospadias. We review evidence concerning indications for various procedures used in primary hypospadias repair, and their complications, urinary function and esthetic results. Available evidence suggests TIP is preferable to Mathieu for distal hypospadias correction. Current data do not identify a clear preference between TIP and onlay flap for proximal repair when there is ventral curvature <30°, or between various flap and graft options when curvature is >31°. A review of objective data helps clarify decision-making for distal hypospadias repair. Additional objective evidence is needed to identify preferred options for proximal hypospadias repair. Measuring glansplasty dimensions (meatal size and distance from meatus to corona) may improve urinary function assessments, and provide additional objective data for decision-making between various surgical techniques.

Abstract
INTRODUCTION Various graft and flap techniques have been proposed for urethral reconstruction in proximal hypospadias repair. The Bracka repair involving the transfer of inner prepuce like a Wolfe graft mostly results in satisfactory results besides a high fistula rate. AIM The aim was to decrease the high fistula rate with Bracka repair; we wanted to use the advantages of vascularized skin in the Bracka method. The aim of this study was to evaluate our results with this modification. STUDY DESIGN Our modification involves using a flap instead of a graft. In the first stage, chordee was corrected by transection of the urethral plate and dorsal midline plication when necessary. Instead of a graft as suggested by Bracka, inner preputial skin with ample blood supply was transferred and stitched to the denuded ventral penile surface. In the second stage after 6 months, this flap was tubularized in the Thiersch-Duplay fashion. Hospital records of patients who had undergone two stage modified Bracka repair between June 2007 and July 2012 were reviewed, including complaints, complications, and need for interventions. RESULTS Thirty-eight patients had undergone this operation. Four patients were lost to follow-up. The main complaint was obstructed urinary flow. Voiding symptoms were first attributed to urethral stenosis, but were, however, found to be due to diverticulum and vortex of the urine in the dilated urethra. Twenty-one patients (61%) had voiding problems and 10 patients (29%) had urinary tract infections. Fistula was observed in 23 and diverticula were observed in 24 patients. Of these, 16 patients had both fistula and diverticula. Only two patients (5%) were free of complications and totally satisfied with the operation, and 23 of the 34 patients had complications requiring intervention (Figure). DISCUSSION Inner preputial flaps used in proximal hypospadias repairs are prone to diverticula formation. They become redundant in time requiring reoperation, thus decreasing the success rate. Careful fixation of the flap to the corpora and allowing time for additional attachment of the urethral plate substitution through fibrotic activity could not overcome this complication. CONCLUSION Our modification of the Bracka technique using a flap for the plate resulted in a high rate of complications (in particular diverticulum formation) and was therefore abandoned. We recommend careful use of flaps in hypospadias surgery and long-term follow-up studies to evaluate actual functional and cosmetic results.

Abstract
This study aimed to assess the association between caudal block and postoperative complications after tubularised incised plate urethroplasty. The medical records of 388 paediatric patients who underwent urethroplasty at a tertiary medical centre were analysed retrospectively. Among the 342 patients included, 216 patients received a caudal block and 72 (21.1%) patients suffered surgical complications. The number of patients having surgical complications was significantly greater among patients who received a caudal block than among patients who did not receive a caudal block (53 (24.5%) versus 19 (15.1%), respectively, p = 0.04). Based on multivariate logistic regression analysis, duration of surgery, caudal block and hypospadias types were independent risk factors for the surgical complications. Patients with caudal block had an odds ratio of 2.1 (95% CI, 1.14-3.81, p = 0.018) for the development of postoperative complications compared with patients without caudal block. This analysis demonstrates that caudal block is associated with surgical complications after tubularised incised plate urethroplasty.

Abstract
This review discusses means for straightening ventral curvature >30°, and then subsequent urethroplasty using either one-stage flaps or two-stage flaps or grafts. The wide variation in reported results from these various techniques makes determination of best management difficult; however, it is clear that complications for repairs done in major centers can range to ≥50%. Given the rarity of proximal hypospadias with ventral curvature >30°, which occurs in approximately 400 newborns annually in the USA, centers should refer these cases to subspecialists within the group who can then develop and maintain expertise.

Abstract
PURPOSE We describe our experience with 2-stage proximal hypospadias repair. We report outcomes, and patient and procedure characteristics associated with surgical complications. MATERIALS AND METHODS We retrospectively studied patients with proximal hypospadias who underwent staged repair between January 1993 and December 2012. Demographics, preoperative management and operative technique were reviewed. Complications included glans dehiscence, fistula, meatal stenosis, nonmeatal stricture, urethrocele/diverticula and residual chordee. Cox proportional hazards model was used to evaluate the associations between time to surgery for complications and patient and procedure level factors. RESULTS A total of 134 patients were included. Median patient age was 8.8 months at first stage surgery and 17.1 months at second stage surgery, and median time between surgeries was 8 months. Median followup was 3.8 years. Complications were seen in 71 patients (53%), with the most common being fistula (39 patients, 29.1%). Reoperation was performed in 66 patients (49%). Median time from urethroplasty to surgery for complication was 14.9 months. Use of preoperative testosterone decreased risk of undergoing surgery for complication by 27% (HR 0.73, 95% CI 0.55-0.98, p = 0.04). In addition, patients identified as Hispanic were at increased risk for undergoing surgery for complications (HR 2.40, 95% CI 1.28-4.53, p = 0.01). CONCLUSIONS We review the largest cohort of patients undergoing 2-stage hypospadias repair at a single institution. Complications and reoperation rates were approximately 50% in the setting of complex genital reconstruction.

Abstract
Failed hypospadias refers to any hypospadias repair that leads to complications or causes patient dissatisfaction. The complication rate after hypospadias repairs ranges from 5-70%, but the actual incidence of failed hypospadias is unknown as complications can become apparent many years after surgery and series with lifelong follow-up data do not exist. Moreover, little is known about uncomplicated repairs that fail in terms of patient satisfaction. Risk factors for complications include factors related to the hypospadias (severity of the condition and characteristics of the urethral plate), the patient (age at surgery, endocrine environment, and wound healing impairment), the surgeon (technique selection and surgeon expertise), and the procedure (technical details and postoperative management). The most important factors for preventing complications are surgeon expertise (number of cases treated per year), interposition of a barrier layer between the urethroplasty and the skin, and postoperative urinary drainage. Major complications associated with failed hypospadias include residual curvature, healing complications (preputial dehiscence, glans dehiscence, fistula formation, and urethral breakdown), urethral obstruction (meatal stenosis, urethral stricture, and functional obstruction), urethral diverticula, hairy urethra, and penile skin deficiency.

Abstract
INTRODUCTION The surgical reconstruction of distal penile hypospadias in a single stage is the standard practice for managing anterior hypospadias. Unfortunately, it is not simple to extrapolate the same principle to proximal hypospadias. There is no consensus among hypospadiologists about whether a single- or multi-stage operation is the optimal treatment for proximal hypospadias. In this review, we assess the currently reported outcomes and complications of both techniques in proximal hypospadias repair. METHODS We searched Medline, Pubmed, Scopus and Ovid for publications in the last 10 years (2002-2012) for relevant articles, using the terms 'proximal hypospadias', 'posterior hypospadias' 'single stage', 'multiple stage', and 'complications'. Articles retrieved were analysed according to the technique of repair, follow-up, complications, success rate, number of included children, and re-operative rate. RESULTS AND CONCLUSIONS The reported complications in both techniques were similar, including mostly minor complications in the form of fistula, meatal stenosis, partial glans dehiscence, and urethral diverticulum, with their easy surgical repair. The outcomes of single- and multistage repairs of proximal hypospadias are comparable; no technique can be considered better than any other. Thus, it is more judicious for a hypospadiologist to master a few of these procedures to achieve the best results, regardless of the technique used.

Abstract
PURPOSE We compared complication rates, urinary symptoms and cosmetic outcomes as perceived by parents of patients undergoing 1 of 4 repairs for proximal hypospadias associated with ventral curvature. MATERIALS AND METHODS A total of 93 patients underwent hypospadias repair between 2004 and 2010. In patients requiring no urethral plate transection the repair consisted of tubularized incised plate urethroplasty (26 patients) or onlay island flap urethroplasty (31). In patients requiring urethral plate transection the repair consisted of onlay island flap on albuginea (18 patients) or 2-stage repair (18). Complications were assessed by chart review. A customized questionnaire and the Pediatric Penile Perception Score were administered to parents to evaluate their perception of urinary symptoms and cosmetic outcomes, respectively. RESULTS After a median followup of 4.5 years (range 2.2 to 8.4) complications developed in 21 patients (23%) without any difference among procedures or between patients who did and did not require urethral plate transection. Parents of 75 patients (80%) participated in the survey without differences among repairs (p = 0.35). Reported urinary symptoms were not different among repairs. For Pediatric Penile Perception Score the only difference concerned the question about penile length (p = 0.03), with the score being significantly better for the techniques requiring urethral plate transection (p = 0.05). The 2-stage repair had a significantly better score for the question about penile length and overall Pediatric Penile Perception Score than all other techniques. CONCLUSIONS Overall complication rates were comparable among repairs and did not increase after urethral plate transection. Urinary symptoms as reported by parents were comparable among the procedures. Perceived penile length was significantly better after urethral plate transection. The 2-stage repair yielded the best cosmetic results.

Abstract
PURPOSE Adults with complications from previous hypospadias surgery experience various problems, including urethral stricture, persistent hypospadias and urethrocutaneous fistula. Innate deficiencies of the corpus spongiosum and multiple failed operations makes further management challenging. MATERIALS AND METHODS We reviewed our prospective urethroplasty database of men who presented with complications of previous hypospadias surgery. Patients were included in study if they had greater than 6 months of followup. Our surgical management was defined as an initial success if there were no urethral complications. The overall success rate included men with the same result after additional treatment. RESULTS A total of 50 men had followup greater than 6 months (median 89) and were included in study. These 50 patients presented with urethral stricture (36), urethrocutaneous fistula (12), persistent hypospadias (7), hair in the urethra (6) and severe penile chordee (7). Patients underwent a total of 74 urethroplasties, including stage 1 urethroplasty in 19, a penile skin flap in 11, stage 2 urethroplasty in 11, urethrocutaneous fistula closure in 9, permanent perineal urethrostomy in 6, excision and primary anastomosis in 6, a 1-stage buccal mucosa onlay in 4, tubularized plate urethroplasty in 3, combined techniques in 3 and chordee correction in 1. In 25 men (50%) treatment was initially successfully. Of the 25 men in whom surgery failed 18 underwent additional procedures, including 13 who were ultimately treated successfully for an overall 76% success rate (38 of 50). CONCLUSIONS Managing problems from previous hypospadias surgery is difficult with a high initial failure rate. Additional procedures are commonly needed.

Abstract
PURPOSE Complex primary hypospadias repair that warrants urethral plate division is treated mostly in two steps, not necessarily in two surgeries. Our aim was to review long-term results with a one-stage strategy based on reconstruction of the urethral plate with buccal mucosa graft and onlay transverse preputial flap anastomosis protected by a tunica vaginalis flap (the three-in-one concept). MATERIAL AND METHODS We were able to report on 35 patients operated for primary scrotal, penoscrotal and perineal hypospadias between March 2002 and June 2008. We reviewed all charts and had phone interviews with patients not seen for the last 24 months. We investigated parameters such as UTI occurrence, fistula, residual curvature, meatal stenosis, urethral diverticula, dehiscence, orchitis and parental perception. RESULTS Surgical complications occurred in 13 patients (37%): 4 meatal stenosis, 4 diverticula, 5 fistulae and 2 residual penile curvatures (total 42%). Meatal dilatation was successful in 2 cases, reflected in fistula resolution. The reoperation rate was 31.5% consisting mostly of simple procedures like fistula closure, meatotomy and penile curvature release, and complex diverticula repair in 4 cases. Parental perception was excellent for 57% (20 patients) and good or acceptable for the remaining. Mean follow-up was 4.6 years. CONCLUSIONS The one-step strategy is associated with 68.5% success in a single operation, whereas 31.5% will need a second repair. We recognize that meatal problems are mostly associated with fistulae and diverticula; therefore, we recommend a final acceptable proximal glandar opening that will not compromise the neourethra.

Abstract
OBJECTIVE We report additional technical modifications and extended application of proximal TIP hypospadias repair in consecutive patients operated by a single surgeon. MATERIALS During a 39-month period, 36 patients underwent primary proximal hypospadias surgery, with 26 undergoing TIP and 10 two-stage repair for a thin urethral plate (UP) (1) or ventral penile curvature (VC) requiring UP transection (9). Of the TIP repairs, 16 had UP elevation from the corpora cavernosa to facilitate VC straightening while maintaining the UP for urethroplasty. All TIP patients underwent two-layer urethroplasty with tunica vaginalis coverage over the neourethra. RESULTS With mean follow up of 12 months (2-38) in 24 TIP patients, 16 had calibration and 11 urethroscopy 6-12 months postoperatively. Complications occurred in three (13%), glans dehiscence (2) and neourethral stricture (1), which represents a significant reduction versus our prior reports. Non-randomized preoperative testosterone in 8/24 with follow up did not influence complication rates. TIP incision of the elevated UP did not divide it into separate strips, or impair vascularity. CONCLUSIONS Dissection of the UP from the corpora facilitates correction of VC while preserving the plate, without increasing TIP urethroplasty complications. Overall, complication rates for TIP have significantly diminished with technical modifications and experience. The role for neoadjuvant hormonal therapy remains unclear. Despite straightening VC preserving the UP, intraoperative assessment deemed it unsuitable for TIP in one case (4%).

Abstract
Koyanagi described an elegant technique for one-stage proximal hypospadias repair. It is particularly suited for the most severe forms of hypospadias. A modified Koyanagi technique was used to repair the hypospadias in 14 children, aged 3-9 years. One child developed breakdown of the suture line, three other children developed small urethrocutaneous fistula needing closure and one child had post-operative meatal stenosis. Despite the high rate of complications, modified Koyanagi's procedure is a good procedure of choice for severe/proximal hypospadias.

Abstract
PURPOSE Reconstruction of long segment urethral stricture disease in adults with a history of pediatric hypospadias repair remains complex secondary to poor urethral blood supply, extensive penile scarring and the need for significant amounts of graft or flap tissue. We describe our experience with staged urethroplasty in this cohort of men. MATERIALS AND METHODS A total of 15 males underwent staged urethroplasty for urethral stricture disease following previous hypospadias repair in childhood. All men underwent 2-stage repair with a minimum of 6 months separating each operation. Bulbar urethral stricture disease due to previous dilation was seen in 2 of the 15 men (14%). Graft sources included buccal mucosa in 12 cases, full-thickness hairless abdominal wall skin in 2, penile skin in 1 and posterior auricular tissue in 1. RESULTS Median patient followup was 22 months (range 5 to 62) after stage 2 closure. Median patient age at presentation was 31 years (range 19 to 57). Mean stricture length was 8 cm (range 5 to 14) and mean graft area was 22 cm(2) (range 10 to 38). There was no clinical evidence of stricture recurrence, fistula or wound dehiscence at last followup in 13 of the 15 men (86%). Two men with a congenital hypoplastic glans were left with distal hypospadias. Minor voiding symptoms were described in 3 of the 15 men (21%) with resolution in all by 6 months postoperatively. CONCLUSIONS We describe outcomes after staged reconstruction for extensive urethral stricture disease in men after previous pediatric hypospadias repair in childhood. At intermediate followup staged urethroplasty provided acceptable outcomes.

Abstract
PURPOSE Although hypospadias repair for preserving the urethral plate is popular among pediatric urologists, applying this procedure to severe hypospadias is controversial. We report the outcome of applying additional modifications to the modified tubularized transverse preputial island flap (TPIF) procedure reported previously [Patel RP, Shukla AR, Austin JC and Canning DA. Modified tubularized transverse preputial island flap repair for severe proximal hypospadias. BJU Int 2005;95:901-4] for repairing severe hypospadias. MATERIALS AND METHODS We retrospectively evaluated our series of 22 patients (mean age 17.5 months) who underwent the modified TPIF with an additional simple modification of meatoplasty with V-incision suture. Patients were followed for a mean period of 18 months. RESULTS After releasing the chordee, the hypospadiac orifice was retracted to become penile in five patients (22.7%), penoscrotal in six (27.3%), scrotal in nine (40.9%), and perineal in two (9.1%). The median length of the neourethra was 46 mm. One-stage repair was successful in 19 patients (86.4%) without any complications. CONCLUSION Our modified TPIF procedure yielded favorable outcomes functionally and cosmetically with a low postoperative morbidity rate. Such a procedure can be considered useful for repairing severe hypospadias when the urethral plate cannot be preserved.

Abstract
OBJECTIVES The repair of severe primary hypospadias represents a major surgical challenge. After initial enthusiasm for single-stage procedures, many paediatric urologists have turned to the alternative two-stage approach after experiencing disappointing results. A single surgeon's experience of the two-stage procedure is reported. METHODS Between 1998 and 2003, 62 boys underwent a two-stage reconstruction for primary hypospadias. Indications for staged repair included proximal meatus (mid-shaft [18 patients], peno-scrotal [23] or perineal [two]), moderate or severe chordee (38 patients), poor glans groove, and lichen sclerosis. Inner prepuce was the graft of choice. Median age was 27.6 months at completion of surgery and median follow-up was 26 months. RESULTS All grafts took well and none of the 62 patients needed revision. One patient developed a haematoma. Maturation of the graft for at least six months ensured the best conditions for the second-stage closure. Overall the cosmetic and functional results after the second stage were excellent. The outcomes were determined by the parents' and surgeon's assessment of function and the cosmetic appearance. Complications included partial glans dehiscense (three patients), residual mild curvature (three) and meatal stenosis (three). CONCLUSION The two-stage repair has proved to be a reliable and reproducible technique with a low complication rate in a difficult cohort of hypospadias patients. Inner preputial skin grafts take very successfully on the ventral surface of the penis, and splitting the glans enables a slit-like meatus to be achieved. Excellent cosmetic results can be anticipated.

Abstract
Delayed correction of genital malformations can have a negative influence on the emotional, psychosocial and cognitive development. Early one-stage-correction to give as near-normal an appearance and function as possible is therefore desirable. This can now be realized in most forms of hypospadias. However, in the rare and most severe forms (5-6%; scrotal and perineal forms) this is technically very demanding. It is extremely difficult for a surgeon to accumulate enough relevant experience, so that one-stage correction is performed only by very few. To investigate results with one-step correction, 100 of 163 cases treated up to 2006 were analyzed. Analysis of the first group of 50 consecutive cases operated on between 1996 and 2001 showed a complication/reoperation rate of 22% (11 cases). The 11 children required a total of 18 (36%) corrective surgical interventions. In 42 cases buccal mucosa was used as a tube onlay. In this group one- stage correction was successful in 39 (78%); 4 patients required two operations and 7 three. Children in group II were consecutive patients operated on between 2003 and 2006. In this group there was a reoperation rate of 12% (6 cases, in 1 of which severe lack of skin made one-stage correction technically impossible). In 45 cases buccal mucosa was used for a tube-onlay. Thus, in group II 44 patients (88%) underwent successful one-stage correction and 6 had two operations; none had three. The significantly lower complication rate in group II is presumably due to greater experience of the surgeons. All strictures observed developed at the level of the glans. In no case was buccal mucosa rejected; nor did any strictures develop between urethra and neo-urethra, being reliably prevented by the connection, with an onlay, to the recessed urethral plate. None of the 100 children became a 'hypospadias cripple'; in all cases satisfactory correction was ultimately achieved. This means that with growing experience one-stage correction can be increasingly reliably achieved. This is not a general call for one-stage correction, but an appeal for patients with these most severe forms of hypospadias to be treated only in specialized centers with the aim of allowing experience to accumulate there so that the results become more reliable.

Abstract
OBJECTIVES To evaluate the results of one-stage and multistage urethroplasty in adults with complications following multiple failed hypospadias repairs. METHODS Sixty adults underwent reconstructive surgery of the following complications after hypospadias repair: stricture (34), residual hypospadias (26), fistula (18), meatal stenosis (11), penile curvature (9), hair (4), diverticula (2), and stone (1). A total of 36% of the patients had one complication and 64% had two or more complications. Twenty-nine patients underwent one-stage repair with buccal or skin grafts or direct repair, and 31 underwent multistage repairs with buccal or skin grafts. RESULTS Mean follow-up was 33.8 mo. Of the 60 cases, 45 (75%) had a final successful outcome and 15 (25%) failed. One-stage repair provided 24 (82.7%) successes and 5 (17.3%) failures. Multistage repair provided 21 (67.7%) successes and 10 (32.3%) failures. Buccal mucosa grafts provided 81% of success in one-stage procedures and 82.3% in multistage procedures. Penile skin grafts provided 80% of success in one-stage procedures and 50% in multistage procedures. CONCLUSIONS Adults with complications following childhood hypospadias repair are still a difficult population to treat with a high failure rate for reoperative surgery.

Abstract
From August 1981 to June 2004, we retrospectively reviewed 66 hypospadias, treated with 123 operations, to analyze the outcome of reoperation based on preoperative antimicrobial prophylaxis. All patients received primary treatment in our hospital, and all had postoperative antimicrobial prophylaxis in all surgical procedures. We define a hypopadias repair as "corrected without fistula" if no urethrocutaneous fistula formation, or complete wound disruption is found within at least a 2-week follow-up period. Of the 123 operations, there were 66 primary repairs and 57 reoperations. The mean age at primary repair was 4.33 years. The overall rate of correction without fistula was 53.0% (35/66), with a mean of 14 months, follow-up. A total of 88 failure repairs resulted from 67 (76.0%) fistulas and 21 (24.0%) disruptions. A higher rate of correction without fistula (81.0%) was related to subcoronal hypospadias (p = 0.020) in three types. The rate of correction without fistula of two-staged repair was lowest in primary operations (12.5%), but these cases had a significantly higher rate of correction without fistula in following reoperations (66.7%, p = 0.043). Of the 123 repairs, only 46 (37%) had preoperative antibiotic prophylaxis, and these had lower early complication rates, both in primary and reoperation groups (42.3% vs 52.5% and 40.0% vs 54.1%, respectively). The differences, however, were not statistically significant (p = 0.231 and p = 0.289, respectively). In terms of rate of correction without fistula, a higher rate of correction without fistula was observed in reoperations with preoperative antibiotic prophylaxis (57.1%), compared to those without prophylaxis (23.1%). This difference was statistically significant (p = 0.031). The data from this study suggest that a lower early complication rate and a significantly higher rate of correction without fistula are related to the hypospadias reoperations with preoperative antimicrobial prophylaxis. The use of broad-spectrum antibiotics before surgery is recommended for these cases. However, more precise and prospective studies are warranted.
