Abstract
INTRODUCTION Acquired megalourethra (AMU) after repair of proximal hypospadias can be a serious complication. An observational retrospective study of its incidence among different types of repair was performed. MATERIALS AND METHODS Clinical charts of patients operated on for proximal hypospadias were reviewed. INCLUSION CRITERIA all primary hypospadias operated in 1991-2004, with the meatus positioned in proximal penile, scrotal or perineal position. RESULTS Of 770 hypospadias cases treated, 130 (16%) were proximal. Seventy-two patients (55%) were treated using preputial flaps: 36 with a tubularized preputial island flap (TIF) and 36 an onlay island flap (OIF). Fifty-eight patients (45%) underwent staged repairs: Belt-Fuquà (BF) in 18 and Bracka procedure in 40 cases. After a mean follow up of 16 years (range 6-19) the overall incidence of complications for each technique was: TIF 36%; OIF 33%; BF 25%; two-stage Bracka 7.5%. The most common complication encountered was neo-urethral fistula. AMU occurred in only 5 cases, none with associated distal urethral stenosis, all in the TIF and OIF groups, and all successfully treated by reduction re-do urethroplasty. CONCLUSION A very small number of the patients operated using preputial island flaps techniques developed AMU. None of the staged repairs developed AMU, and this is the preferred choice in proximal hypospadias when the urethral plate requires division and/or substitution. All cases of AMU resolved after urethral tapering.

Abstract
INTRODUCTION Our purpose was to evaluate patients who underwent failed hypospadias repair. PATIENTS AND METHODS We evaluated 4 different groups of patients who underwent failed hypospadias repair. Group 1: patients who underwent only urethral surgery; group 2: patients who underwent only corpora cavernosa surgery; group 3: patients who underwent urethral and corpora cavernosa surgery; group 4: patients who underwent complex reconstructive surgery. Success was defined as a functional urethra without fistula, with glandular meatus and acceptable esthetic appearance of the genitalia. RESULTS Out of 1,176 patients, group 1 included 301 patients (25.5%), group two 60 patients (5.2%), group three 166 patients (14.1%) and group four 649 patients (55.2%). The mean follow-up was 60.4 months. Out of 1,176 cases, 1,036 (88.1%) were considered successful and 140 (11.9%) failures. CONCLUSION In the majority of patients (55.2%) with failed hypospadias repair, urethral reconstruction is associated with complex surgical procedures to fully resurface glands, penile shaft and genitalia.

Abstract
OBJECTIVES A concealed penis is defined as a phallus of normal size buried in prepubic tissue (buried penis), enclosed in scrotal tissue (webbed penis), or trapped by scar tissue after penile surgery (trapped penis). We report our results using a standardized surgical approach that was highly effective in both functional and cosmetic terms. METHODS From January 2002 to December 2005, 56 patients (median age 7 years) underwent surgery for a buried penis, 11 (median age 5 years) for a webbed penis, and 20 (median age 8 years) for a trapped penis. All 20 patients with a trapped penis had previously undergone circumcision for phimosis, except for 3 (1 for multioperated lymphangioma, 1 for repaired hypospadias, and 1 for corrected glanular epispadia). All webbed penises were phimotic, requiring circumcision. The surgical technique consisted of complete exteriorization of the shaft and reconstruction of the penopubic and penoscrotal angles. These maneuvers, however, proved extremely straightforward, with the addition of an incision along the scrotal raphe without any incision of the penile skin. RESULTS All the patients were observed for at least 1 year after repair. Recurrence was observed in 3 boys with a buried penis (5.3%); all 3 boys were obese. Two cases of a trapped penis (10.0%) recurred, but no case of a webbed penis recurred. Regarding complications, 2 patients with a buried penis presented with mild lymphatic stasis of distal shaft that spontaneously subsided within a few months. CONCLUSIONS The scrotal approach we have described has simplified the complete exteriorization of the penile shaft, with easy bleeding control, avoiding the use of flaps, grafts, and additional ventral Z-plasty often described in published reports. In addition, the cosmetic results were judged to be good by the parents.

Abstract
In the early '80s, tubularized preputial flap has been intensively used for proximal hypospadias. Even if not yet used today, there are a conspicuous number of patients treated in that time that today present with obstructive symptoms. In this paper, authors propose an initial experience of an alternative strategy to the complete re-do. Three patients (6, 9 and 27 years old) were diagnosed of stenosis at the junction of the tubularized preputial flap and the native urethra. Proximal and distal urethra was normal at the urethrogram in all cases. A augmentation was performed. One year follow up is free of obstructive symptoms and flowmetry is normal. The technique proposed seems to be the best balanced owing to a minimal invasivity and better results along time.

Abstract
Combined buccal and bladder mucosa represents the only reconstructive solution for panurethral strictures by Lichen Sclerosus (LS) in which the need to remove the diseased urethral mucosa and to reconstruct a long and circumferential urethral tract, collides with the limit of buccal mucosa harvesting and with the lack of others substitutive tissues not lichen involved. The use of buccal mucosa for glandular urethral reconstruction avoids the direct contact of the bladder mucosa with the air and, therefore its drying-retraction-stenosis. The bladder mucosa tube is covered and supported by residual urethral spongiosum that has been saved during the phase of diseased urethral mucosa removal. The described technique is the only reconstructive chance in severe panurethral strictures by LS. In these cases the alternative would be the definitive urethral perineal stomy.

Abstract
Hirschsprung's disease (HD) is a major cause of congenital bowel obstruction in children. Classical management includes stoma creation, a pull-through procedure, and restoration of bowel continuity. Colostomy may be also pulled through directly at second operation. Since the first report of a single stage (SS) primary pull-through without colostomy for HD, in 1980, several patients have been treated according to this procedure, even in neonatal period. All of them had a favourable outcome with better compliance of families and less hospital stay. The Authors reviewed the clinical records of 22 patients selected among 36 treated for HD between 1992 and 2000; in all, disease extended to rectum-sigma-descendent; all cases of "total aganglionosis" or "ultra short" cases were excluded. Fifteen patients underwent SS repair: 11 neonates were operated at mean age of 69 days (range 14-172). In four infants diagnosis was made later (mean age 15 +/- 9 months) and SS repair was performed 8 days after (range 4-14). Seven patients underwent multiple stage (MS) repairs for clinical reasons: pull-through of the previous colostomy was performed at mean age of 171 days (range 47-330). A Duhamel procedure with an Endo-GIA linear stapler was performed in all No differences in gestational age or birth weight were found in both groups. Complications were observed only in the MS group (2 related to colostomy, 1 to postoperative adhesions). The Authors conclude that primary SS treatment of HD is safe and effective even in newborn patient, reduce familiar stress and hospital stay. The lower morbidity and complication rates could be explained by the limited bowel manipulation. Accurate histological-hystochemical diagnosis and meticulous preoperative bowel management should be part of the management.

Abstract
AIM Primary gastrointestinal perforations have an incidence of between 1% and 3% in NICU patients. The 3 Centers participating in this study cover nearly 40% of the NICU population of the Lazio Region--Italy. The aim of this study is to discuss factors affecting survival in patients affected by a primary intestinal perforation. METHODS From 1991 to 2001, 67 cases of 85 with a neonatal gastrointestinal perforation, were related to primary bowel lesions. Necrotizing enterocolitis (NEC) was not always the cause of perforation and in many patients an isolated bowel lesion without signs of NEC was found. The aim of this study was to examine clinical and intraoperative findings of NEC and non NEC perforations and their impact on survival. A relevant number of these patients were extremely low-birth weight (ELBW). Controversies about treatment of this category of neonates are discussed. RESULTS Patients were 37 males and 30 females (mean birth weight 1 274.8 g, mean gestational age 28.9 weeks, mean age at perforation 10 days). Overall survival was 56.8%. Patients were divided by intraoperative findings in 2 groups: NEC (n=48), or isolated intestinal perforation (IIP) without signs of NEC (n=19). Differences between these 2 groups with regard to birth weight, maturity, associated cardiac anomalies (patent ductus arteriosus, PDA) were significant. NEC and IIP behaved as 2 distinct entities, each with peculiar clinical (age at perforation, oral feeding, need of ventilatory support) and radiological aspects. At surgery, multiple lesion on necrotic bowel were typical of NEC versus single, isolated perforations on healthy bowel typical of IIP. Overall survival was almost identical in the 2 groups (59% vs 58%). ELBW patients (55% of the total neonatal intestinal perforations) were also studied. There were 21 patients with NEC and 16 with IIP. The 2 groups were different in age at perforation, previous oral feeding and associated cardiac anomalies (PDA). Overall survival was 62% for NEC and 50% for IIP. A laparotomy was always performed. Temporary peritoneal drainage was done in 4 cases only. Results were better when intestinal diversion was performed rather than resection and primary anastomosis. Almost all NEC patients had multiple perforations and extended bowel necrosis. CONCLUSION NEC is the most frequent cause of neonatal intestinal perforation. This is a quite distinct entity from IIP, which must always be differentiated preoperatively and which is most frequently found among low birth weight newborns. As far as surgical treatment of perforation among ELBW neonates is concerned, peritoneal drainage might be reasonably performed when a single lesion on healthy bowel as in IIP is clearly diagnosed but it could be inadequate for NEC patients.

Abstract
BACKGROUND Long term follow-up of a prenatally diagnosed hydronephrosis usually extends no longer than the first two years of life. During this period spontaneous reduction occurs in most of the dilatations, not sustained by obstruction or reflux. Late recurrence of hydronephrosis is considered to be unusual. The aim of the present work has been to verify the risk of recurrent hydronephrosis long time after reduction and to identify factors associated to recurrence. MATERIALS AND METHODS In a seven years period (1992-99) 276 patients with hydronephrosis unrelated to reflux, duplex kidney, megaureter or vesical obstruction have been observed. Among them, 231 were referred after prenatal diagnosis. Hydronephrosis of grade III or more was recorded in 73/231 with a pelvic diameter > or = 15 mms at ultrasonography (US) and a normal counter-lateral kidney. Surgical treatment was elected in 39 cases on the basis of a separate function < 40%, deterioration during follow-up, or occurrence of clinical symptoms. Thirthy four cases were treated conservatively and four were lost at follow. Among the remaining 30 cases, 14 had a pelvic diameter lager than 20 mms. They were followed for a mean of 16.6 months (range 7-26) and spontaneous significant reduction of pelvic dilatation was recorded in all of them. RESULTS Patients were recalled after a mean of 32.1 months from the last US. In 3 cases among 14 with a pelvic diameter larger than 20 mms a recurrent severe hydronephrosis was found respectively at 39, 56, and 68 months. In two of them, isotopic scans documented a reduced separate function. The third case reported recurrent symtpoms. A pyeloplasty was performed in all cases. CONCLUSIONS Spontaneous reduction in most of the prenatally detected cases of neonatal hydronephrosis within the first two months of life make follow-up beyond this term controversial, whenever complete disappearance of pelvic dilatation has been documented. The Authors report three cases with severe hydronephrosis (pelvic diameter > 20 mms) among a group of patients treated conservatively. Long time after spontaneous reduction, recurrent hydronephrosis was documented in all by US, associated to deterioration of separate function and symptoms. Long term follow-up is recommendable in severe cases of prenatally detected hydronephrosis cases, even after reduction, to warrant from recurrence and renal damage.

Abstract
Hypospadias surgery is one of the most difficult areas in pediatric urology and has been characterized by constant evolution. Some of the surgical techniques proposed in the past are now considered inadequate because of an unacceptable complication rate or poor functional and aesthetic results. The key for assessing a surgical technique (or a particular aspect of it) is continuous evaluation through long-term patient follow-up. We present the medical records of 693 patients over 10 years, all operated on by the same surgeon (the first author), with a minimum of 12 months of follow-up. The overall complication rate was 6.49% (45 cases). The most frequent complication was urethral fistula, occurring in 28 patients (62%). Other complications were redo for penile deformity or meatal retraction (eight cases, 17%), megalourethra (five cases, 11%), meatal stenosis (two cases, 4%), and urethral stenosis (two cases, 4%). We have noticed an increased rate of complications in patients older than 12 months (18.7% vs. 3.4% in patients younger than 12 months) and in patients operated on at puberty or later (15%). We have seen no difference in the complication rate related to the type of hospitalisation (day surgery vs. traditional hospitalisation). Regarding the relationship between the type of complication and the type of defect, except for the constant presence of fistulae, a high incidence of megalourethra was seen in proximal defects treated with preputial graft. The sexual outcomes of 32 subjects are presented. Multiple factors influence the final result, but the most important factor is the surgeon's own experience. Knowledge of different techniques and delicate tissue handling are essential. Our experience shows that the ideal age for surgery is 8-12 months. Owing to a minimal emotional impact on the child and to a reasonable use of economical resources, we consider day surgery the ideal way to treat these patients whenever possible. Even in the absence of complications, follow-up must be continued at least until the end of puberty and, when possible, up to the patient's sexual debut. Adequate interviews with the patients (principally teenagers and young adults) are the best way to evaluate their need for psychological support.

Abstract
Although the use of surgical staples is a well established practice in intestinal tract surgery on adults, their role in biliodigestive anastomoses in adults and children has been more limited. The Authors describe a 12-year-old girl with a type-IV choledochal cyst, who was successfully treated with cyst excision and Roux-en-Y hepaticojejunostomy created with a surgical stapler.

Abstract
Bronchogenic cyst a bronchopulmonary foregut malformation. An intramural esophageal localization has rarely been reported in respect to more common esophageal duplications or leiomyoma. The authors describe a case of bronchogenic cyst of the esophageal wall in a 3 years old girl. It was an misdiagnosed cause of dysphagia and was revealed by endoscopy and CT scan after two uneffective antireflux procedures performed in different institutions, which caused a worsening of symptoms. Complete excision of the lesion through a thoractomic approach and a redo of the antireflux procedure were followed by complete recovery.

Abstract
The authors reviewed two groups of patients with ureteropelvic junction obstructión divided by age and mode of presentation: patients with neonatal asymptomatic hydronephrosis diagnosed by prenatal ultrasonography and patients with symptomatic hydronephrosis. It was assumed that in these patients we are observing a continuous spectrum of the same pathology; nevertheless, some relevant differences were found between the two groups. Diuretic renograms did not show any change in postoperative renal function among prenatally detected cases while a significative improvement followed surgery among most of symptomatic cases. A possible explanation could be found in the obstructive mechanism which was responsible of obstruction in a significative proportion of these patients. Lower polar vessels produce a progressive symptomatic hydronephrosis in an healthy kidney in respect to intrinsic obstruction which are mainly found among prenatally detected cases and which are frequently associated to congenital renal damage unresponsive to surgery.

Abstract
Bilateral renal vein thrombosis after an appendectomy has never been reported in the pediatric literature. We describe the case of a 10-year-old boy who developed this very unusual complication following appendectomy for gangrenous appendicitis with peritonitis. Color duplex Doppler is the most appropriate investigation to allow correct diagnosis and immediate medical treatment. Peritoneal dialysis is a simple and effective tool to prevent permanent damage to renal function.

Abstract
We describe the case of a 6-year-old boy who presented post-renal anuria and renal failure five days after appendectomy and drainage of a periappendicular abscess. Only mild dilatation of the urinary tract was observed on ultrasound and small calculi were documented at the ureterovesical junction bilaterally. Diuresis was restored by the insertion of uretercatheters. Awareness of this complication and immediate treatment can avoid permanent impairment of renal function.

Abstract
PURPOSE We evaluated the feasibility of urethroplasty using a free peritoneal graft in a rabbit model. MATERIALS AND METHODS In 12 male rabbits a urethral defect was created by excising a 3 x 5 mm. portion of the ventral urethral surface. The defect was immediately repaired with a free peritoneal graft harvested via a left flank incision. RESULTS There were 2 intraoperative deaths and 1 death on day 8 postoperatively. These animals were excluded from study. The remaining 1, 4 and 4 rabbits were sacrificed 3, 5 and 9 weeks after surgery, respectively. Macroscopic examination of the urethra revealed no stenosis or diverticula, while a fistula was present in 3 of the 9 animals. Histological study of the fistulous tracts showed chronic granulomatous inflammation. In the remaining 6 rabbits there was graft adherence. The inner surface of the graft was uniformly lined with normal urothelium, while in some cases acute inflammatory cells were present in the subepithelial layer. CONCLUSIONS Our experience indicates that the ease of harvesting free peritoneal grafts and their satisfactory adherence to the urethra makes them a valid alternative for repairing urethral defects.

Abstract
We describe a case of H-type rectovaginal fistula associated with the Currarino triad (anorectal stenosis, sacral defect, presacral mass). Presenting symptoms included passage of feces per vaginam, signs of intestinal subocclusion without perianal inflammation, left leg paresis and foul-smelling urine. An anterior sacral meningocele was repaired at the age of three months. At age 18 months the fistula was excised through a perineal approach after creation of a protective colostomy. Diagnostic and therapeutic aspects of this malformation are discussed.
