Abstract
Background Clinical classification of the urethrocutaneous fistulas (UCFs) was designed to help the surgeons in (1) categorizing the fistulas, (2) selecting appropriate treatments, (3) keeping record at presentation and discharge, and (4) transferring information while referring a patient with recurrent fistula to a higher center.
Methods This retrospective study comprised of 68 patients with UCFs who reported in the “Hypospadias and VVFs Clinic” between 2004 and 2016. The study was performed to determine the incidence or etiology of the UCFs. It was rather performed to classify fistulas into different categories depending on the number of fistulas: A (5 fistulas), B (16 fistulas), C-a (28 fistulas), C-b (4 fistulas), D (4 fistulas), and E (11 fistulas). Category A fistulas healed conservatively. Category B fistulas underwent transection of the fistula tracts (tractotomy), purse-string closure, or multilayered closure (fistulorrhaphy). Category C-a fistulas were reenforced by preputial or penile skin flaps or waterproofing flaps. Category C-b fistulas underwent re-tubularization of their neourethral plates and eccentric closure of peno-preputial skin. The urethral plates of category D fistulas were re-tubularized after 3 to 6 months and cover was provided by the Cecil-Culp procedure. Category E fistulas had associated hairy urethra, stricture distal urethra, stricture with diverticulum, perifistular scar-induced chordee, long narrow urethral plate, balanitis xerotica obliterans (BXO), and short reconstructed neourethra. Accordingly, appropriate corrective measures were taken. Miscellaneous category F was excluded from the study.
Results Except for one in category D, none of the patients had any recurrence of fistula. One patient of category E had residual diverticulum.
Conclusion The designed clinical classification of UCFs is simple. Treatment was in accordance with reconstructive ladder wherein complexity of treatment paralleled with increasing complexity of fistulas.

Abstract
OBJECTIVE The aim: In this study, we present and evaluate the vest-over-pants technique as a simple way to correct urethrocutaneous fistulas after hypospadias. PATIENTS AND METHODS Materials and methods: Between October 2018 and June 2020, twenty male patients aged 5 to 20 years came to us with post hypospadias repair fistula, these patients underwent vest-over-pant repair of their fistula. The size of fistula was ranging between 2.5-5 mm. The distribution of fistula was coronal (3 patients), distal penile (9 patients), midshaft (2 patients) and proximal penile (6 patients). In 14 patients there were single fistula and 6 patients had more than one fistula. Eleven of patients were exposed to a previous failed fistula repair procedure. RESULTS Results: Six months after the operation, the fistula recurred only in 2 patients, and our operation was successful in 90% of cases without complications. CONCLUSION Conclusions: The vest-over-pants technique is a simple and effective way to treat penile fistulas after hypospadias in properly selected patients. It is a technically simple procedure with a short learning curve and no major postoperative complications.

Abstract
Background Hypospadias is the most common penile malformation affecting up to one in 300 live male births. In general, a urinary diversion (urethral stent or bladder catheter) is maintained in situ for two to seven days or more after hypospadias repair. Because of the low level of evidence, the latest guidelines of the European Association of Urology and the European Society of Paediatric Urology provide no recommendations concerning the timing of catheter removal after hypospadias surgery. In this study, we aimed to compare the outcomes of hypospadias surgery (tubularized incised plate urethroplasty, TIPU) following early versus late bladder catheter removal. Methodology In total, 62 patients were included in this study. All patients underwent TIPU by the same team of surgeons. All patients were divided into the following two groups: group A (32 patients) had their catheter removed on or before the fifth postoperative day, and group B (30 patients) had their catheter removed after the fifth postoperative day. All patients were scheduled for an outpatient assessment after two weeks, at one month, after three months, and at six months if necessary. Results The mean age of patients in group A was five years (three to seven years) and in group B was five years (four to 7.25 years) with a p-value of 0.378. Among the early complications of the surgery, the occurrence of wound infections, urinary tract infections, and urinary retention was comparable among the two groups. The rate of bladder spasms (0% versus 13.3%, p = 0.033) was significantly higher in group B than in group A. The rate of urinary retention (12.5% versus 0%, p = 0.045) was significantly higher in group A than in group B. Superficial wound infection occurred in two out of 32 patients in group A (6.3%) and two out of 30 patients in group B (6.7%) (p = 0.94). Both groups had similar incidences of wound complications. Urinary tract infections also had a similar incidence in both early and late catheter removal groups, i.e., one out of 32 patients in group A (3.1%) and three out of 30 patients (10%) in group B (p = 0.271). Urinary extravasation following hypospadias repair occurred in two out of 32 patients (6.3%). No extravasation was noted in the late catheter removal group. However, the difference was not clinically significant (p = 0.164). Two patients in both groups developed urethrocutaneous fistula (6.3% in group A versus 6.7% in group B). However, the difference was not clinically significant. Meatal stenosis developed in three out of 32 patients in group A and two out of 30 patients in group B (9.4% versus 6.7%; p = 0.696). One patient in the early catheter removal group developed urethral stricture as a late complication. None of the patients in the late catheter removal group developed this complication. Conclusions The occurrence of long-term complications of TIP hypospadias repair was not affected by the early removal of the bladder catheter. The shortcomings of our study were its descriptive nature and the small sample size. Further prospective randomized controlled trials are needed to ascertain the safety of early catheter removal and improvement in quality of life in the immediate postoperative period.

Abstract
PURPOSE To review our management of urethral fistulae following hypospadias repair over a 24-year period. To showcase our innovations, particularly the purse-string closure technique. METHODS We reviewed our prospectively maintained database from 1997 to 2020 to identify patients with fistula. Two main surgical techniques were used: traditional linear closure and purse-string suture. Other innovations included anchoring skin to corpora and intersectional skin closure. RESULTS Sixty two patients presented with 73 urethral fistulae after hypospadias repair. 55/62 were operated: 28-purse-string technique, 23-linear closure, 4-redo urethroplasty. Cure after the first attempt was achieved in 26/28 (93%) in the purse-string group and 16/23 (70%) in the linear group (p = 0.015). Spontaneous resolution occurred in 6/62 patients (9.6%), in 3 spontaneously and in 3 after a single dilation. 1 patient awaits surgery. Closure after first fistula repair was 22/24 (92%) in distal hypospadias and 20/27 (74%) in proximal hypospadias (p = 0.051). CONCLUSION Remarkably, conservative management was succesful in almost 10% of urethral fistulae, either spontaneously or after a single dilation. Purse-string closure, rarely described in the literature, coupled with our other innovations, helped bring down our recurrence rates significantly with no patient needing more than two surgeries for cure.

Abstract
BACKGROUND Most hypospadias patients undergo 1 surgical procedure and go on to live normal lives. However, there is a small subset of patients who have remaining functional complications after their repair. Patients presenting with diffuse scarring of the urethral plate and a shortage of penile skin for closure are referred to as "hypospadias cripples." We present our experience using tissue expanders in the treatment of reoperative hypospadias with skin deficiency. METHODS We retrospectively reviewed hospital records from 2009 to 2019. Five hypospadias cripple patients were encountered. A multidisciplinary team involving plastic surgery and pediatric urology collaborated a 3-stage reconstructive plan:Stage 1-Scar excision and buccal mucosal graft harvestStage 2-Dorsal tissue expander placementStage 3-Tissue expander explantation, creation of neourethra, and skin closure. RESULTS Successful skin closures were achieved in all patients. There were no cases of expander explanation. Average time between tissue expander placement and final reconstruction ranged from 3 to 4 months. Complications included 2 cases of penile cellulitis, 1 with an associated abscess, and 2 limited urethrocutaneous fistulas, which were addressed with an additional operative procedure. CONCLUSIONS The 3-stage approach is advantageous in treating hypospadias cripple patients. This population can benefit greatly from tissue expander placement after buccal result with an acceptable complication rate. Using a multidisciplinary approach is beneficial in treating these complex patients.

Abstract
PURPOSE To evaluate the outcomes of patients who underwent a post-circumcision coronal fistula repair by means of a three-step repair technique: glans flap, urethral closure, and dartos flap interposition. MATERIALS AND METHODS We retrospectively reviewed the outcomes of 23 patients with postcircumcision urethrocutaneous fistulas who were treated at our institution between January of 2014 and December of 2018. The patients included in this review had exclusively a coronal fistula with an adequate glans bridge between the fistula and the urethral meatus and underwent surgical repair at least 6 months after the initial injury. We excluded from the study patients who had multiple level fistulas, glans dehiscence and patients that were lost to follow-up less than 6 months post fistula repair. RESULTS The median age at the time of the repair was 9.2 (range: 6.3 to 31) months. The fistulas were classified according to their size as small (ranging from pinpoint to ≤4 mm; n = 19) or large (>4 mm; n = 4). The overall success rate was 87% (20 of 23 patients). The success rates for the small and the large fistulas were 94.7% (18 of 19) and 50% (2 of 4), respectively. An indwelling urethral stent was used in all patients, except in those with pinpoint fistulas. The mean follow-up was 19.9 (6-60) months. CONCLUSIONS Post-circumcision coronal urethrocutaneous fistulas less or equal to 4 mm in diameter without glans dehiscence can be successfully repaired using a three-step repair technique, with a recurrence rate of less than 6%. For larger fistulas, a formal urethroplasty is recommended due to high recurrence rate of the three-step repair technique. LEVEL OF EVIDENCE Case Series (Level IV).

Abstract
Abstract
Background
We aim to evaluate isoamyl 2-cyanoacrylate as an intervening layer in the surgical repair of the urethra-cutaneous fistula (UCF) after hypospadias in comparison with the classic surgical repair technique.
Methods
Between January 2017 and July 2018, 40 patients with UCF were randomized into two equal groups. Group I represented a multilayered closure with dartos fascia flap while using cyanoacrylate glue as an interposition layer, while group II represented the same procedure without applying the glue. We followed up our patients for 6 months following the procedure to evaluate a successful closure.
Results
Forty patients were available for evaluation at the end of our study. There was no statistically significant difference between the two groups regarding their demographic data. The mean fistula size was 3.25 ± 0.64 and 3.15 ± 0.75 mm in group I and II, respectively, with a statistically significant difference. Successful UCF closure was achieved in 80% of cases in group I (16/20) and 70% of group II (14/20) with no statistically significant difference. There was no statistically significant difference between both groups as regards the occurrence of mild complications in the postoperative period, which was 10% in both groups.
Conclusion
The application of cyanoacrylate during UCF repair was feasible and safe. The successful repair of UCF was found to be higher with cyanoacrylate. However, we could not demonstrate a statistically significant difference between the two groups.

Abstract
Background The effect of caudal block (CB) on the incidence of urethroplasty complications in hypospadias repair remains controversial. The evidence is conflicting, and some confounding bias issues need to be addressed. We sought to study a more homogenous group of distal hypospadias patients undergoing primary tubularized incised plate (TIP) repair by a senior pediatric urology surgeon in the past 2 years to examine the relationship between urethroplasty complications and the use of CB. Methods We reviewed our database to identify consecutive patients who had undergone hypospadias repairs by a senior director surgeon at our Center between January 2018 and November 2020. To be eligible to participate in the study, patients had to meet the following inclusion criteria: (I) have distal hypospadias; (II) have undergone a primary TIP repair; and (III) have attended follow-up appointments for a minimum period of 6 months. The primary outcome was the development of urethroplasty complications during the follow-up period. The principal variable of interest was whether or not CB was used perioperatively. The patients were categorized into a CB group (general anesthesia combined with CB) or a control group (general anesthesia only). Other potential risk factors were analyzed, including patient age at operation, patient weight, glans width, and the length of the urethral plate defect. Results Thirty (12.2%) of the distal patients developed postoperative surgical complications. The postoperative surgical complication rates were similar between the different anesthesia groups. Weight, the length of the urethral plate length, and glans width did not contribute to the risk. Age was the only independent risk factor for postoperative surgical complications, and the complication rates increased in older patients. Conclusions Our data from consecutive TIP repairs in distal hypospadias patients indicated no association between the use of CB anesthesia and the postoperative urethroplasty complication rate. Patients who were older in age when they underwent surgery had a higher risk of complications.

Abstract
The simple closure of a urethrocutaneous fistula is technically easy, but direct suture tension is associated with a higher urethral fistula recurrence rate. We describe a multilayer direct closure with a longitudinal relaxing incision in urethrocutaneous fistula repair, avoiding the tension associated with the direct suturing of the surgical skin wound. From March 2015 to January 2018, 46 urethrocutaneous fistulas in 34 patients were repaired at the Hypospadias Center of our hospital. During the operations, after the urethral fistula closure, a longitudinal penile skin incision was created 0.5 to 1.5 cm from the edge of the surgical wound. The penile skin wound was closed, and the longitudinal penile skin incision made during the operation was used as a relaxing incision to reduce the skin tension of the closed fistula area. The urethral fistula repairs were successful, and no signs of infection or poor healing were present at the closure sites of the penile skin wounds. The relaxing incisions gradually healed within 7 to 21 days after operation, and the residual scars were soft and did not significantly differ in color from normal skin. The key to increasing the success rate of urethrocutaneous fistula repair is creating a longitudinal relaxing penile skin incision. The technique aims to avoid the direct suture tension of the penile skin wound, thereby providing a favorable environment for the normal healing of the urethral fistula suture site.

Abstract
PURPOSE To evaluate the feasibility of ventral urethrotomy, dorsal inlay (Asopa) technique in management of urethrocutaneous fistula. The Asopa technique has been employed for management of urethral stricture repair but has not been described in adult penile urethrocutaneous fistula. METHODS This is a retrospective review of IRB-approved databases of patients undergoing urethral reconstruction from two urologic reconstruction units. In this technique, the fistulous tract is circumscribed and excised, leaving a larger ventral urethral defect with healthy edges. The ventral-sagittal urethrotomy is extended, a dorsal urethrotomy made, and a graft inlaid dorsally to augment the urethral caliber prior to tension-free closure of the ventral urethrotomy. RESULTS From 2010 to 2019, ten patients underwent repair of urethrocutaneous fistula using the Asopa technique. Median patient age was 33.5 years (IQR 35.5). All fistulae involved penile urethra, eight had concomitant adjacent urethral stricture. Five patients failed prior hypospadias repair, three developed fistulae after surgery for penile urethral stricture, and two developed fistulae after extensive debridement (hidradenitis and Fournier's gangrene). Of these ten patients, oral mucosa graft was used in nine and preputial graft in one to augment the urethra. At median follow-up of 50.5 months (IQR 26.5), 80% (8/10) of patients demonstrated durably patent urethra, with no recurrence of fistula. CONCLUSION The Asopa technique is an established option for augmenting urethral caliber for urethral stricture disease. We demonstrate in our series that this technique can be applied to patients with urethrocutaneous fistulae.

Abstract
OBJECTIVE This study aimed to investigate the risk factors of fistula recurrence after primary urethrocutaneous fistulectomy in children with hypospadias. MATERIAL AND METHODS The study included 63 children who underwent fistulectomy for urethrocutaneous fistula (UCFs) that occurred after urethroplasty for hypospadias, between February 2009 and December 2018. The patients were divided into 2 groups: successful group 1 and failed group 2. For data analysis, we included the demographics of the patients, the details of the previous urethroplasty (the type of hypospadias and the location of the meatus after complete chordectomy), the presence of meatal stenosis or urethral stricture after urethroplasty, and the size of the UCFs. The Student t-test and the chi-square test were performed to analyze the data using the Statistical Package for Social Sciences software. RESULTS The overall success rate of primary urethrocutaneous fistulectomy was 81.0% (51/63 children). The most common location of a secondary fistula was the penoscrotal area 5 (41.6%). There were no statistically significant differences in age (p=0.501), weight (p=0.063), body mass index (p=0.924), history of low birth weight (p=0.454), and history of prematurity (p=0.381). The type of hypospadias (p=0.007) and urethral defect length (p=0.021) were identified as independent risk factors for failed urethrocutaneous fistulectomy. There were no statistically significant differences in meatal stenosis (p=0.431), postoperative stricture (p=0.587), fistula location (p=0.173), multiplicity (p=0.588), and fistula size (p=0.530). CONCLUSION The type of hypospadias and the length of the urethral defect are the significant risk factors for secondary fistula recurrence after primary urethrocutaneous fistulectomy.

Abstract
BACKGROUND Delayed urethrocutaneous fistula (UCF) presentation after hypospadias repair is rarely reported. The aim of this study is to report our experience with delayed UCF presenting more than 5 years after hypospadias repair. METHODS We conducted a retrospective review of patients who underwent UCF repair (CPT codes 54,340 and 54,344) at our institution between 1997 and 2017. Delayed UCF presentation was defined as a single normal urinary stream after initial hypospadias repair and subsequent presentation of a UCF/s urinary stream more than 5 years after initial hypospadias or UCF repair. Demographic and clinical data were reviewed after approval from our institutional review committee. RESULTS We identified 12 patients with delayed UCF. The mean age at hypospadias repair was 12.3 months (Range 6-32). The mean time to delayed UCF presentation was 11.5 years (Range 7.1-15.8). Four patients with delayed UCF (33.3%) required additional surgery for UCF recurrence with a mean time to recurrence of 2.2 years (Range < 1-5.6). CONCLUSIONS Delayed UCF presentation can occur more than 15 years after initial repair. Pubertal penile skin changes and increased genital awareness in older children may be contributing factors as all but one presented at age 10 years or older. LEVEL OF EVIDENCE III.

Abstract
OBJECTIVES To evaluate the outcomes of recurrent urethrocutaneous fistula repair using tunica vaginalis graft as an intermediate protective layer. METHODS We retrospectively reviewed the data of 45 children with recurrent urethrocutaneous fistula who underwent tunica vaginalis graft repair between February 2011 and January 2019. The repair was carried out at least 6 months after a previous fistula repair. Follow up at an outpatient clinic was scheduled on a weekly basis for 1 month, then monthly for 6 months and then annually. During follow up, every patient was evaluated by history taking. The site of repair and the act of micturition were inspected. Urine analyses together with culture and sensitivity tests were carried out if required. Successful repair was defined as the absence of recurrence, with good force and caliber of the urinary stream. RESULTS This study included 45 patients with recurrent urethrocutaneous fistula who were managed with a tunica vaginalis graft as a second layer. The mean age of patients was 6.7 ± 2.8 years. The mean postoperative hospital stay was 5.5 ± 0.7 days. The repair was successful for 43 (95.6%) patients, and urethrocutaneous fistula recurrence was reported for two (4.4%) patients, which were repaired after 6 months. In all patients, the cosmetic appearance of the penis was satisfactory without torsion or ventral chordee. CONCLUSION Tunica vaginalis graft is a simple and fast procedure that is highly effective as a protective second layer for recurrent urethrocutaneous fistula repair.

Abstract
INTRODUCTION Our aim was to evaluate and share our urethrocutaneus fistula repair results in adult patients who had been operated for hypospadias in their childhood. MATERIAL AND METHODS The data of totally 48 patients who had been treated for urethrocutaneous fistula after hypospadias surgery in our department from May 2008 to January 2015 analyzed retrospectively. Patients' age at fistula repair, age at first hypospadias surgery, fistula size, localization and number, distal urethral obstruction status and surgical outcomes of fistula repairs were recorded. All patients were controlled three months after the repair for surgical outcomes. RESULTS Fistula repair performed in 45 patients. Mean age was 21.46 (20-26). Nineteen patients (42.2%) underwent first hypospadias surgery under the age of 7 years; 8 patients (17.7%) between 7 and 15 years, 18 patients between 15 and 20 years. Tubularized incised plate urethroplasty (TIPU) was performed in 40 patients (88.9%), extragenital tissue was used in 5 patients (11.1%). Twenty two patients (48.9%) had 1 or 2 operations, 17 patients (37.8%) had 3-5 operations and 6 patients (13.3%) had 6 or more operations. Thirteen (28.9%) coronal, 24 (53.3%) subcoronal, 6 (13.3%) penile and 2 (4.4%) penoscrotal fistulas were observed. While a single fistula was observed in 35 patients, multiple fistulas were seen in 10 patients. A fistula diameter les than 5mm was detected in 37 patients, and larger than 5mm in 8 patients. Fistula recurrence was observed in 3 patients at follow-up examinations carried out at 3 months postoperatively. The number of operations was more than 5, the fistula diameter was larger than 5mm and the fistulas were coronal in all three recurrent fistulas. CONCLUSION According to our results fistula size, previous surgery and well-vascularised, one or two layer tissue were the important factors in the success of fistula repair after hypospadias surgery.

Ointment Fistulography: Introducing a Novel Technique for Single or Multiple Urethrocutaneous Fistula Diagnosis After Hypospadias Surgery. Urology 2017; 106:231-232. [PMID: 28982617 DOI: 10.1016/j.urology.2017.03.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Revised: 03/23/2017] [Accepted: 03/28/2017] [Indexed: 11/17/2022]
Abstract
INTRODUCTION AND OBJECTIVE Hypospadias is a common congenital malformation of the male genital tract. The most frequent complication after hypospadias repair is urethrocutaneous fistula.1 Its incidence has been reported up to 35% worldwide.2 The diagnosis of these fistulas is sometimes challenging particularly with tiny and multiple fistulas. Usually, parents complain of urinary spraying, sprinkling, or passing a single stream of urine from the undersurface of the penis after the surgery. Urethrocutaneous fistulas are not always visible on physical examination. Locating the fistula and status of the surrounding skin is very important in order to choose the surgical repair technique.3 The patency and anatomy of the distal urethra should also be determined before the repair surgery.4 That is why urologists usually use retrograde urethrography or cystoscopy to find the location of fistula. However, these modalities have their own risk for children and are not always helpful. Sometimes the contrast media inserted can clog some fistulas especially near the glans and preclude the diagnosis. We present an easy technique to screen for urethrocutaneous fistulas after hypospadias surgery. TECHNIQUE In this technique (Video 1), an antibiotic ointment is inserted through the meatus while the base of the penis is held; the ointment is then gently pushed through the meatus. As shown in the video, the ointment will protrude through the fistulas anywhere along the shaft. This technique can also be performed reversely as the ointment inserted from the fistulas will protrude from the meatus. For younger children under the age of 3, we exclusively perform this technique under anesthesia on the repair surgery day, whereas in toddlers we perform this technique in the office and once again under anesthesia right before the repair surgery. RESULT This technique shows even tiny and multiple fistulas not detectable on physical examinations. We have used this technique in our clinic and have not missed any fistulas. The diameter of the protruded ointment in reverse fistulography is an indicator of the distal urethral diameter. Therefore, in case of narrow ointment diameter, distal urethral strictures should be suspected as correction of distal obstruction is an important determinant in the success rate of fistula repair surgery.5 CONCLUSION: We suggest this diagnostic technique as a safe, inexpensive, easy, office-based, feasible, and reproducible method. Negative urine culture is not required for this examination. Also, there is no need to insert contrast media as in retrograde urethrography or induce anesthesia as in cystoscopy. We believe this simple technique help urologists around the world to diagnose this common complication of hypospadias surgery without the need for special equipment.

Abstract
BACKGROUND Urethrocutaneous (UC) fistulae are common complications after hypospadias surgery and they have been a serious problem for surgeons since the repair was first attempted. We present the results of our multicentre retrospective study for repairing UC fistulae using the Patio ("preserve the tract and turn it inside out") repair described by Malone. MATERIALS AND METHODS A total of 16 boys (Eschweiler 2, Lingen 4, Reading 10) at the ages of 1-10 years were treated for UC fistulae. Instead of excising the fistula tract, it is preserved and turned inside out, this creates a flap valve inside the urethral lumen. After a circumferential incision around the skin and meticulous dissection of the fistula tract, a 2/0 nylon suture is passed down the tract and brought out through the external urinary meatus. As a result, the fistula tract is inserted into the urethral lumen. In order to keep the fistula tract inverted, it is sutured to the tip of the external urinary meatus, or fixed by an angler lead (modification from Lingen). Due to the narrow base, the excess tissue atrophies postoperatively and leads to an appealing cosmetic result. RESULTS A total of 9 fistula repairs were performed on an outpatient basis without using a transurethral catheter; 7 boys were treated on an inpatient basis with an average length of stay in the hospital for 1-2 days with/without catheterization. During a mean follow-up of up to 4.5 years, only one fistula recurrence occurred; no other complications were observed. CONCLUSION The Patio repair for urethrocutaneous fistula is an outpatient, simply reproducible surgical technique without the necessity of transurethral catheterization. The short-term results are impressive; long-term results of a larger patient cohort will follow.

Abstract
BACKGROUND Caudal and penile blocks are the most popular regional anesthetic techniques used in infants and children undergoing urological surgery. A recent report has suggested that penile venous pooling resulting from caudal blocks could affect surgical outcomes after hypospadias operations. OBJECTIVE The aim was to report our experience in patients with distal hypospadias undergoing repair with caudal versus penile block. STUDY DESIGN A retrospective clinical database was constructed for patients who underwent distal hypospadias repair by a single surgeon (M.P.B.) at our sponsoring institutions for the time period 2008-2013 (n = 192). Collected data included hypospadias classification (glanular, coronal, subcoronal), chordee status, perioperative anesthesia (caudal vs. penile), and assessment of postoperative complications (fistula and meatal stenosis). RESULTS Risk ratio (RR) analysis for all distal hypospadias cases revealed that there is a higher risk of developing complications in patients who underwent caudal anesthesia than in patients who underwent penile block RR for a complication was 3.70 (95% CI 1.05-13.03; p < 0.04) (Figure). DISCUSSION Similar to other papers in the literature, we found that patients who underwent caudal anesthesia had more complications than those who underwent penile block. The limitations of this study include not adjusting the results according to the severity of hypospadias. CONCLUSION The main goal of this study was accomplished by demonstrating that, in our series, caudal anesthesia is associated with a higher risk of fistula formation after undergoing distal hypospadias repair than penile block.

Abstract
Background Circumcision is a common minor surgical procedure and it is performed to a varying extent across countries and religions. Despite being a minor surgical procedure, major complications may result from it. In Ghana, although commonly practiced, circumcision-related injuries have not been well documented. This study is to describe the scope of circumcision-related injuries seen at the Komfo Anokye Teaching Hospital in Kumasi, Ghana. Methods The study was conducted at the Urology Unit of the Komfo Anokye Teaching Hospital in Kumasi. Consecutive cases of circumcision-related injuries seen at the unit over an 18 month period were identified and included in the study. Data was collected using a structured questionnaire. Data was entered and analysed using SPSS version 16. Charts and tables were generated using Microsoft Excel. Results A total of 72 cases of circumcision-related injuries were recorded during the 18 month period. Urethrocutaneous fistula was the commonest injury recorded, accounting for 77.8 % of cases. Other injuries recorded were glans amputations (6.9 %); iatrogenic hypospadias (5.6 %), and epidermal inclusion cysts (2.8 %). The majority of children were circumcised in health facilities (75 %) and nurses were the leading providers (77.8 %). The majority of circumcisions were conducted in the neonatal period (94.7 %). Conclusion Circumcision-related injuries commonly occurred in the neonatal period. Most of the injuries happened in health facilities. The most common injury recorded was urethrocutaneous fistula but the most tragic was penile amputation. There is the need for education and training of providers to minimise circumcision-related injuries in Ghana.

Abstract
BACKGROUND Several techniques have been used to repair mid-penile hypospadias; however, high failure rates and major complications have been reported. In this study, we describe a novel technique using a well-vascularized flap of the inner and outer preputial skin. METHODS A total of 110 male children with hypospadias underwent repair by our technique between 2008 and 2015. The inclusion criteria were children with mid-penile or slightly more proximal hypospadias, with or without ventral chordae, and an intact prepuce of the cobra eyes variety. Recurrent cases, patients with other preputial types, and circumcised children were excluded from this study. The prepared flap was sutured in its natural longitudinal orientation to the created urethral plate strip to form a neo-urethra over a urethral catheter. Outcome measures included surgical success without the formation of a urethra-cutaneous fistula, no ischaemia of the flaps, glans dehiscence or infection and functional outcome and cosmetic appearance. RESULTS The median follow-up duration was 3.3 years. There were 63 cases of mid-penile hypospadias (57.3 %), and in 47 cases (42.7 %), the meatus was slightly more proximal. The age of the patients ranged from 1.1 to 8.0 years, with a mean age of 4.6 ± 1.2 years. Surgery was successful in 106 (96.4 %) cases. Minor complications occurred in 11 patients (10 %) and included oedema of glans in ten patients and bluish discoloration on the ventral aspect of the glans close to the suture line in three patients. All patients improved within 2 weeks after surgery. Long-term follow-up revealed a properly functioning urethra with a forward, projectile, single, compact, and rifled urinary stream of adequate calibre and cosmetically acceptable repair. No cases of meatal retraction, meatal stenosis, urethral stricture, or acquired urethral diverticulum occurred. DISCUSSION Our technique is different from the split prepuce in situ technique. We create a narrow strip of the urethral plate that facilitates glanular closure, and we use the inner and adjacent outer skin in a vertical manner to preserve excess skin for penile coverage. Prepuce is split at midline to preserve more preputial skin with favourable dartos tissue for penile skin coverage. The glans is closed using a stitch-by-stitch method that has not been described previously. CONCLUSION This study presents a novel technique for mid-penile hypospadias repair using a preputial skin flap with excellent results in terms of short- and long-term outcomes.

Abstract
AIM The aim is to determine the incidence and timing of urethrocutaneous fistula diagnosis after hypospadias surgery. METHODS A retrospective review of all patients who had both initial hypospadias surgery and subsequent fistula repair from 1995 to 2012. A comparison was made between patients who had an initial onlay island flap procedure and those who had a tubularised incised plate repair. RESULTS Patient age at initial surgery ranged from 6 months to 16 years of age. The median time to fistula presentation was 8.5 months with a range of less than 1 month to 13.9 years post-hypospadias surgery. The median time to fistula repair was 17 months. The overall fistula rate was 8%. There was no significant difference between the rates of fistulae for onlay island flap (9%) versus tubularised incised plate procedure (7%). CONCLUSIONS Urethrocutaneous fistulae can present many years after the original hypospadias repair. The majority are diagnosed within the first year after surgery. Rates of fistulae are probably underreported due to short follow-up, but more importantly, due to patients transferring to other surgeons for fistula repair.

Abstract
PURPOSE We report the efficacy of staged segmental urethroplasty (SSUP) versus non-staged urethroplasty (NSUP) for treating scrotal/perineal hypospadias (SPH). METHODS Between 1997 and 2015, 29 SPH patients underwent UP (SSUP: n = 15; NSUP: n = 14). Incidences of urethrocutaneous fistula (UF), stenosis of the neourethra (SNU), diverticula formation, and residual chordee (RC) were compared. Differences were statistically significant if p < 0.05. RESULTS The difference in mean age at NSUP (3.2 ± 1.3 years) and at the final stage of SSUP (5.5 ± 2.4 years) was significant (p < 0.05). Mean operative times for NSUP and SSUP (total for all stages) were not significantly different (231.5 ± 117.5 versus 272.5 ± 99.4 min); however, the incidence of postoperative complications was significantly less in SSUP (n = 1; UF) compared with NSUP (n = 6; 2 cases of UF, 3 cases of SNU, and 1 case of RC; (p < 0.05). Mean follow-up was significantly shorter in SSUP; 1.4 ± 1.2 years versus 7.0 ± 4.5 years in NSUP (p < 0.05). CONCLUSION SSUP would appear to be effective for treating SPH because of a significantly lower incidence of UF, SNU and RC during the first postoperative year, the period when complications have been reported to arise most frequently.

Abstract
OBJECTIVE To present the results of temporary urethral re-catheterization in order to aid spontaneous closure of early fistulas after hypospadias repair. METHODS AND TECHNIQUE Children presenting with early fistulas (within 2 weeks of initial catheter removal) after hypospadias repair underwent urethral calibration and re-insertion of a urethral catheter under intravenous anesthesia. The catheter was removed after 2 weeks. RESULTS Nine children (age 1-9 years) with early fistulas had re-catheterization: six (66%) had spontaneous healing of the fistula by 2 weeks, which remained closed at subsequent follow-up. CONCLUSION The simple technique of urethral re-catheterization may allow spontaneous healing of some early fistulas after hypospadias repair.

Abstract
INTRODUCTION Urethrocutaneous fistula (UCF) complicating hypospadias surgery is associated with compromised tissue and perfusion at the UCF site, especially if recurrent. We report our technique for UCF repair. METHODS Between 1997 and 2014, we treated 35 UCF in 26 postoperative hypospadias patients; 12 UCF were recurrent (mean 2.5; range 1-5). Mean age at UCF repair was 9.3 years (range 2-22). Our repair involves making a superficial incision 3-5 mm around the fistula orifice, placing multiple stay sutures in the outer edge of this incision and dissecting only the epidermis under traction for 7-10 mm. This technique does not compromise underlying connective tissue or tissue perfusion. The skin layer of the inner edge of the circumferential incision is trimmed completely and the fistula closed using 7/0 absorbable interrupted sutures. A pedicled external spermatic fascia, or tunica vaginalis flap is then mobilized to cover the repair site through a subcutaneous tunnel and the skin closed. A urethral catheter is placed and removed the next day. Duration of follow-up was calculated as the period from discharge home until the last outpatient clinic attendance. RESULTS Repair was successful in all cases. Penile cosmesis was acceptable to good without any testicular complications or scrotal deformity. At mean follow-up of 7.4 years (range 0.4-17.3) there have been no recurrences. CONCLUSIONS Our technique allows UCF to be repaired effectively and is also indicated for recurrences.

Abstract
BACKGROUND Urethrocutaneous fistulae (UCFs) represent one of the most frequent causes of morbidity after urethroplasty. Hypospadias can be repaired using different surgical techniques, but-regardless of technique-the incidence of UCF ranges between 10% and 40%. Surgical repair of UCF remains the treatment of choice, even if some patients need further surgery because of recurrences. Cyanoacrylates have been used as skin suture substitutes, and some evidence suggests a beneficial effect when these adhesives are used as an adjuvant in the management of UCF. Here we describe the results of management of UCF using 2-octyl cyanoacrylate (OCA) compared with surgical repair. METHODS A randomized clinical trial conducted from January 2008 to December 2012 included 42 children with UCF complications after urethroplasty for hypospadias. Twenty-one children were assigned to receive OCA as ambulatory patients and 21 were treated surgically. The main outcome variable was closure of the UCF. The estimated costs of both treatments were also calculated, as were absolute risk reduction (ARR), relative risk reduction (RRR) and number needed to treat (NNT) to prevent a surgical intervention. RESULTS The mean numbers of UCF were 1.3 in the OCA group (n = 28) and 1.1 in the surgical group (n = 25) with no statistically significant difference. The external orifices measured were 2.96 ± 1.0 mm and 3.8 ± 0.89 mm, respectively (NS). Sixty per cent of the UCFs treated with cyanoacrylate were completely closed and 68% of the surgical group healed completely (NS). More than one reoperation to improve complications was needed in the surgical group (3.5 ± 1.2). The clinical significance of the therapeutic usefulness of OCA was demonstrated by an ARR of 0.08, RRR of 0.25 and NNT of 12 to avoid further surgical treatment. The total costs of adhesive applications and reoperations were $US 14,809.00 and $US 158,538.50, respectively. CONCLUSIONS The results showed a similar success rate for both treatments. However, sealant use should be considered before surgical treatment because this is a simple outpatient procedure with a reasonable success rate.

Abstract
OBJECTIVE Urethrocutaneous fistula is the most common complication of hypospadias repair. Tubularized incised plate urethroplasty (TIPU) has been used for the management of distal fistulas. This study reports the usage of TIPU in the treatment of large penile fistulas. MATERIALS AND METHODS Between April 2002 and September 2012, 15 patients with large penile fistulas who were managed with TIPU were included in the study. The fistulas were sited along the penile shaft from proximal to distal penile localization. Glanular and coronal fistulas were excluded. The surgical technique was completed according to the standard TIPU technique. The surrounding scar tissue of the fistula was circumferentially excised, and the urethral plate at the level of the fistula was incised to provide performance of loose urethral tubularization. A urethral stent was kept for 5-7 days. RESULTS The mean age of the patients was 7.3 ± 3.1 years. Primary operation of these patients was tubularized preputial island flap (n = 6), on-lay preputial island flap (n = 4), and TIPU (n = 5). The sites of the hypospadias fistulas were as follows; penoscrotal (three), mid-penile (eight) and subcoronal (four). Fistulas recurred in two patients after fistula repair. The postoperative follow up of the patients was 12.4 ± 7.7 months. CONCLUSION TIPU may be used safely for the treatment of fistulas after hypospadias repair.

Arab J Urol 2014; 12:116-26. [PMID: 26019935 PMCID: PMC4435762 DOI: 10.1016/j.aju.2014.02.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2013] [Revised: 02/01/2014] [Accepted: 02/05/2014] [Indexed: 11/25/2022] Open
Abstract
Objectives To objectively assess the functional and cosmetic outcomes of a modified tubularised incised-plate (TIP) urethroplasty (Snodgrass) technique, with particular attention to the uroflowmetry study and Hypospadias Objective Scoring Evaluation (HOSE) score. Patients and methods In a prospective case-series study, 43 consecutive patients with primary distal hypospadias were evaluated. The modified Snodgrass technique included an extension of the midline relaxing incision of the urethral plate from within the hypospadiac meatus to the very tip of the glans. The neourethra was tubularised starting at the neomeatus and proceeding proximally. The neourethra was covered with either a single or double dartos flap. In toilet-trained boys, at least 3 months after surgery, the flow pattern, maximum (Qmax), and mean urinary flow rate (Qave) were recorded, and the results plotted against a recently published flow-rate nomogram from normal children. The postvoid residual urine volume was measured using ultrasonography. The cosmetic outcome was assessed using the HOSE system. Results The native meatus was coronal in 11 (26%), subcoronal in 23 (53%) and distal penile in nine (21%) of the patients. The median (range) age was 4.2 (0.5–14) years. The neourethra was covered by a single dorsal dartos flap in 25 and a double dartos flap in 18 patients. At a median (range) follow-up of 6 (3–24) months, the uroflowmetry findings in 26 uncomplicated toilet-trained boys with a median (range) age of 5.2 (3.3–14) years showed an abnormal Qmax below the fifth percentile in four (15%), with the Qave above the fifth percentile in all. The flow pattern was bell-shaped in nine boys (35%), interrupted/intermittent in five (19%), slightly flattened in 10 (39%) and a plateau in two (8%). A vertical slit-like meatus located at the distal glans was created in 39 (91%) boys, and at the proximal glans in four (9%). The urinary stream was single and straight in 39 and angled in four patients. A straight erection was observed in 42 (98%) boys. Four patients had preoperative mild penile torsion of <45°, that was corrected by surgery. The mean (SD, range) HOSE score was 15.8 (0.6, 13–16). Two patients had a small, single subcoronal fistula. Conclusion Extending the midline urethral plate-incision in the modified Snodgrass repair to the apical part of the glans can be done safely with a high rate of locating the neomeatus at the glans tip, with no resultant meatal stenosis. The functional and cosmetic results of the procedure are good, but long-term data and comparative studies are required to confirm these results.

Abstract
OBJECTIVE Boys with complex penile anomalies often undergo multiple operations, leaving a paucity of unscarred skin for further reconstructive procedures. Our objective was to evaluate the ability of tissue expansion to provide local skin for successful phallic reconstruction. MATERIALS AND METHODS Eighty boys (mean age of 11.9 years) with hypospadias (n = 42) or epispadias (n = 38) formed the study cohort. All patients had undergone at least one failed reconstructive operation. Indications for tissue expansion included scarcity of penile skin with urethral stenosis, urethrocutaneous fistula, chordee, and/or residual defect. One or two expanders were placed under the skin of the penile shaft and removed at the time of reconstruction. RESULTS Average time between expander placement and reconstruction was 10.9 weeks. Mean follow-up time was 25.3 months. Complications during expansion occurred in 33 patients (41.3%). Twenty-two patients (27.5%) had at least one expander removed prematurely and 46.9% were replaced. Expansion yielded adequate tissue for reconstruction in 76 patients (95.0%). Successful outcomes were achieved in 39 patients after initial reconstruction and 25 patients after further intervention, yielding an overall success rate of 80.0%. CONCLUSION Tissue expansion is a useful tool with an acceptable rate of complications for phallic reconstruction in patients who have failed prior surgical reconstruction.

Abstract
OBJECTIVE We aim to report a single surgeon's experience of using a penile skin advancement flap with penile dartos interposition for hypospadias fistula repair. PATIENTS & METHODS All hypospadias fistula repairs performed in our unit by this paediatric urologist between 2000 and 2012 were identified from a prospectively recorded database. Patients' case-notes were reviewed retrospectively gathering data on surgical technique, post-operative care and fistula recurrence on follow-up. Only those boys having repair by this advancement flap technique were included. A urethral catheter was left in situ in all patients for 5-7 days. Repairs performed using other techniques were excluded. RESULTS 20 consecutive patients had fistula repair by the advancement flap technique. This was the primary repair in 19 boys, and was repair of a third fistula occurrence in one. The median age at fistula repair was 3.7 years (1.6-15.3). The median follow-up was 4 months (3-73). One boy failed to attend any follow-up. No recurrence has yet been identified in any of the 20 patients. CONCLUSION The penile skin advancement flap with dartos interposition technique was very successful in our series in both primary fistula repair, and in a patient who had multiple previous operations.

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
Context: Developing countries. Aims: To propose a operative classification of Chordee without hypospadias (CWH) with its management. Settings and Design: Tertiary referral centre; Retrospective study from January 2000 to January 2011. Materials and Methods: Total 26 patients were classified peroperatively into sixtypes (A: Cutaneous chordee→ Degloving skin and dartos (1/26); B: Fibrous chordee→ chordectomy (4/26);C: Corporocavernosalchordee→ Corporoplasty ± Urethral mobilization (4/26); D: Urethral tethering with Hypoplastic urethra→ Urethral mobilization ± urethral reconstruction because of hypoplastic urethra (14/26); E: Congenital short urethra→ excision of urethra from the meatus and urethroplasty (2/26); and F: Complex chordee→ Degloving ± Corporoplasty ± urethroplasty (1/26 patients). The follow-up over 6 months to 9 years were analyzed. Statistical Analysis: SPSS soft ware version 17.0 for Windows. Results: The mean age of surgery was 5.33 ± 0.11 years. The success rate defined on uroflowmetry and voiding cystourethrography was 65.6%. The coronal urethra-cutaneous fistula developed in 26.9% (7/26) {including 7.7% (3/26) of associated metal stenosis}. The urethral stricture developed in 3.8% (1/26). Conclusions: CWH needs stepwise surgical management. The operative classification may help in better understanding and management of this difficult entity. Meticulous tissue handling and urethroplasty is needed for good and promising results.

Abstract
BACKGROUND The wide spectrum of circumcision urethral injury/fistula makes selection of appropriate repair methods challenging in sub-Saharan Africa. This paper reports on the outcome of repair-oriented categorization in a Nigerian center. METHODS Consecutive children presenting with circumcision urethral injury/fistula at the University of Benin Teaching Hospital were categorized into six repair-oriented groups in 2009-2011. RESULTS 21 children were treated. Except in 2 cases, early neonatal circumcision at an average age of 8 days (range 4-14 days) had been performed, the majority (52%) by paramedics at home. Categories of injury/fistula based on severity ranged from isolated fistula (38%) which required fistula excision and repair (category A) to severe ventral urethral/coronal/glanular avulsion (29%) which required urethral plate tubularization/ventral penile reconstruction (category F). Overall, successful first-stage repair was achieved in 19 (91%) children. Meatal stenosis (2), urethral stricture (1), which responded to serial dilatation, and minor urinary leakage (2), which was closed at second stage, were the post-repair complications. Adequate penile size and straight penis on erection were achieved in all cases. Cosmetic outcome was excellent in 16 (76%) cases, good in 4 (19%) and fair in 1 (5%). CONCLUSION Repair-oriented categorization, which could be useful to practitioners in similar settings, was satisfactory in managing urethral injury/urethrocutaneous fistula.

Abstract
Objective To compare the outcome of a single vs. a double-layer dartos interposition for preventing a fistula after tubularised incised-plate (TIP) distal hypospadias repair. Patients and methods We retrospectively reviewed the records of patients with primary distal hypospadias who had the hypospadias repaired between February 2009 and June 2011, operated by one surgeon (S.A.K.). In all of the children a standard TIP urethroplasty was performed, which was covered by a dartos fascial flap fashioned using one of two techniques, i.e. in Group I (48 patients) double dartos preputial flaps were used, and in Group II (52 patients) a single dorsal dartos flap was used and transposed ventrally via a ‘buttonhole’. The fistula rate and other complications related to each group were recorded. Results The mean (range) follow-up was 12 (6–22) months for Group I and 14 (6–24) months for Group II. The result was considered a success in 96% of Group I and 92% of Group II. In Group I there were no fistulae, while in Group II there were four fistulae (8%) detected; this difference was statistically insignificant (P = 0.1). Meatal stenosis was associated with a fistula in one patient in Group II but not in the other three. In Group I a meatal stenosis developed late after complete healing of the urethroplasty, with no associated fistula. The repair broke down in one patient in Group I (2%). Conclusion A double-dartos neourethral cover in TIP hypospadias repair seems to be more effective than a single layer for preventing a fistula, despite there being no statistically significant difference between the groups. However, the protective effect of double-dartos flaps must be appropriately evaluated in a prospective, randomised and controlled study in more patients.

Abstract
Hypospadias is one of the most common congenital genital anomalies for which surgery early in life is indicated. The surgical treatment is changing progressively, often by repeating treatment strategies that have been used decades ago. Indeed, historically two-stage procedures were replaced by one-stage procedures and nowadays two-stage procedures gain new interest. The same for reconstructions using the urethral plate, which decades ago were based on the Thiersch Duplay principle. In the 1980s, preputial onlay flaps were most often used and today we see a new interest in the use of the urethral plate. The actual surgical approach to hypospadias is described and technical details are given.

Abstract
OBJECTIVE To show that splinting of the urethral repair with acellular collagen matrix is a safe and useful adjunct in the procedure to manage complex urethrocutaneous fistula. Urethrocutaneous fistula is one of the most common complications of hypospadias surgery. Management of persistent urethrocutaneous fistula is challenging because it is complicated by a lack of or poor quality of tissues at the site of repair. METHODS Between 2006 and 2011, 12 boys underwent urethrocutaneous fistula repair (10) or redo urethroplasty (2) using acellular collagen matrix by a single surgeon. Mean age was 6.8 years (range 3.1-14.8); median follow-up was 2.5 years (range 0.4-3.8). Urethrocutaneous fistula was closed and acellular collagen matrix was used as a splint. All the patients were assessed by an independent observer; all boys were successfully treated with no further recurrence of fistula. RESULTS On palpation, the previous site of the acellular collagen matrix implant was soft and subtle, revealing healthy underlying tissues. Cosmetic outcome was excellent in all patients, with no signs of scarring or tethering. All patients had a single good urinary stream. Uroflows were within normal range of age-matched standardized nomograms with nonobstructive bell-shaped curves. One boy had late wound infection, which healed with debridement, but had no recurrence of fistula. CONCLUSION Splinting of the urethral repair with acellular collagen matrix in redo surgery is safe and is a useful adjunct that effectively prevents further recurrence of complications such as urethrocutaneous fistula.

Abstract
BACKGROUND The management of recurrent urethrocutaneous fistula (RUCF) is a challenging problem that poses a serious difficulty for the hypospadias surgeon. We report here a novel technique in which a double unfurled dartos subcutaneous flap is utilized in the treatment of patients with RUCF. METHODS We retrospectively reviewed the records of all our patients who underwent surgical treatment of urethrocutaneous fistula with this new operative method after previously failed fistula repair. The main novelty of this technique is the use of two opposite medium thickness flaps, unfurled from the inner surface of the dartos fascia and spread over the fistula and each other so as to cover the urethral suture line completely, and fixed to the surrounding corporal tissue. RESULTS Eight patients with 11 RUCFs (with localizations varying from subcoronal to penoscrotal fistula opening) underwent surgical correction with the new method. There had previously been at least 3 recurrences in 6 of these patients, and different closure techniques had been used. RUCF diameter was <4 mm in all patients. Surgery was performed at the earliest following a 6-month healing period since the last fistula repair attempt. All of the RUCFs were repaired successfully with the technique. After a follow-up of at least 6 months, none of the 8 patients had developed recurrence of the fistula, and there were no postoperative complications. CONCLUSION The double unfurled dartos subcutaneous flap method appears to be a simple and appropriate procedure with which to repair recurrent mid-shaft and proximal urethral fistulas after failed hypospadias repair.

Abstract
Introduction: The commonest complication following hypospadias repair is occurrence of urethrocutaneous fistula. The smaller fistulas (<2 mm) are easier to close with a simple closure whereas larger ones (>2 mm) with good vascular surrounding skin require a local skin flap closure for avoiding overlapping suture lines. For the recurrent/larger fistulas with impaired local surrounding skin - incidence of recurrence is significantly reduced by providing a waterproofing interposition layer. Aims: To study the effect of size, location, number of fistulas and surrounding tissues in selecting the procedure and its outcome. To identify various factors involved in the recurrence and to formulate a management in the cases where recurrence has occurred. Patients and Methods: This study of 35 cases of urethrocutaneous fistula repair was done from July 2006 to May 2009 to achieve better results in fistula management following hypospadias surgery. Statistical analysis used: X2 test and Fisher's exact test. Results: The overall success rate for fistula repair at first attempt was 89% with success rates for simple closure, layered closure and closure with waterproofing layer being 77%,89% and 100%, respectively. The second attempt success rate at fistula repair for simple closure and closure with waterproofing layer were 33% and 100%, respectively. At third attempt the two recurrent fistulas were managed by simple closure with a waterproofing interposition layer with no recurrence. All the waterproofing procedures in this study had a success rate of 100%. Conclusions: The treatment plan for a fistula must be individualized based on variables which has an effect on the outcome of repair and to an extent dictates the type of repair to be performed. The significantly improved success rates with the addition of a waterproofing layer suggests the use of this interposition layer should be done at the earliest available opportunity to prevent a reccurence rather than to reserve it for future options.

Abstract
OBJECTIVE To evaluate the outcomes of three surgical techniques for the closure of urethrocutaneous fistula (UCF) after hypospadias repair. MATERIALS AND METHODS Fifty-one patients (mean age 6.5 years) who underwent UCF closure between June 1998 and February 2008 were divided in to three groups depending on fistula size; group I had <2 mm and (n = 17, 33.4%), group II had 2-4 mm (n = 21, 41.2%) and group III had >4 mm or multiple fistulas (n = 13, 25.4%). Group I patients were treated by excision and simple closure. Patients in group II and III were treated with flip flap technique along with the wrapping of repaired area with scrotal dartos flap and tunneled tunica vaginalis flap (TVF), respectively. RESULTS Mean surgical time was 45 min (range 30-55), 60 min (range 50-75) and 80 min (range 60-100) in three techniques, respectively. The mean follow-up was 3.5 years (range 6 months-10 years). No patient had recurrence of fistula in group III, while 2 (9.5%) and 4 (25.4%) patients in groups II and I, respectively, had recurrent UCF. No postoperative complications were encountered in the testis or the scrotum. No patient had torsion or deviation of penis. CONCLUSION Simple fistula closure carries a higher risk of recurrence even in small sized fistulas. The application of scrotal dartos or TVF for wrapping the repaired area gives excellent results and they are easy to harvest with no harmful effects on the scrotum or testis.

Abstract
OBJECTIVE To report the challenges and outcomes of hypospadias repair in a developing country such as Nigeria. PATIENTS AND METHODS This was a prospective study of children who underwent hypospadias repair at the University of Benin Teaching Hospital in 2003-2007. The challenges and outcome of repair were documented with photographs to assess cosmetic results. RESULT A total of 149 operations were performed on 127 children with hypospadias, aged between 9 days and 12 years (mean 2.3 years+/-2.1) with 33 (26.0%) presenting after circumcision; 118 (92.9%) were single and 9 (7.1%) multistage, while 13 had closure of post-hypospadias repair fistulae and redo surgery. Non-availability of suitable pediatric urethral catheters, special dressing materials and microsurgical instruments/sutures, presentation after circumcision, and lack of parents/caregivers' motivation were major challenges. Transurethral urinary diversion, dressing with petroleum jelly impregnated with antibiotic/chloramphenicol ointment, mosquito forceps, scrotal skin flaps, size 6/0 polyglactin sutures, and organized counseling/home visits were employed. Repair was successful in all the children: excellent cosmetic results in 121 (95.3%), fair in 5 (3.9%) and poor in 1 (0.9%). Urethrocutaneous fistula was the main complication with no mortality recorded. CONCLUSION Despite the challenges, improvising with available materials, counseling of parents/caregivers, adequate patient recruitment and appropriately timed repairs gave encouraging results.

Timing of the presentation of urethrocutaneous fistulas after hypospadias repair in pediatric patients. J Urol 2008; 180:1753-6. [PMID: 18721981 DOI: 10.1016/j.juro.2008.03.112] [Citation(s) in RCA: 38] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2007] [Indexed: 11/22/2022]
Abstract
PURPOSE We evaluated the timing of the presentation of urethrocutaneous fistulas after hypospadias repair and the development of recurrent urethrocutaneous fistulas after prior fistula repair. MATERIALS AND METHODS We reviewed the charts of all patients with urethrocutaneous fistulas following hypospadias repair who were seen from 1995 to 2005. Age at hypospadias repair, hypospadias level, hypospadias repair type, time when the parent/patient noted the fistula, date/type of fistula repair, time when fistula recurrence was noticed, date/type of secondary repair and date of last followup were documented. RESULTS A total of 26 patients with urethrocutaneous fistula were seen, of whom 15 had undergone at least 1 prior operation elsewhere. Of the patients 58% and 61% with fistulas following hypospadias repair and recurrent fistulas following the initial fistula, respectively, presented in the immediate postoperative period. Of the patients 23% with initial fistulas presented more than 2 years after hypospadias repair (up to 17 years later), while only 5.5% with recurrent fistulas presented more than 1 year after fistula repair. Age at presentation with initial fistulas after hypospadias repair was 0 to 12 months in 5 patients, 12 to 24 in 6, 24 to 36 in 6, 36 to 48 in 2 and more than 48 in 7. Mean followup was 5.5 months (range 0 to 69). CONCLUSIONS While many urethrocutaneous fistulas develop immediately following hypospadias repair, almost a quarter present well beyond the typical followup of many urologists. These findings suggest that reported rates of urethrocutaneous fistula may be underestimated and longer followup may be warranted. Late recurrence of urethrocutaneous fistula is rare with 5.2% seen at more than 1 year, suggesting that more limited followup may be appropriate in these patients.

Abstract
OBJECTIVES To demonstrate that urethrocutaneous fistulas can be repaired under local anesthesia in adult patients without catheters. METHODS From 1998 to 2006, 96 patients with urethrocutaneous fistulas underwent repair under local anesthesia. The patients were divided into two groups in terms of whether they did or did not have a catheter placed. The catheterized group included 45 patients and the uncatheterized group included 51 patients. The uncatheterized patients were discharged on the operation day, and the catheterized patients were discharged 1 to 4 days postoperatively. Patients were reevaluated on the 7th postoperative day and after 3 months in terms of wound infection, urethral stricture, and fistula recurrence. RESULTS All patients tolerated the fistula repair well under local anesthesia. The success rate of fistula repair was 93.3% and 94.1% in the catheterized and uncatheterized groups, respectively. Wound infection was seen in 6 patients in the first group but was not noted in the uncatheterized group. Fistulas recurred in 3 patients in each group (6.6% and 5.8%) after 3 months postoperatively. CONCLUSIONS Catheterless fistula repair with local anesthesia in adults is an effective, safe, and inexpensive procedure.

Abstract
OBJECTIVES To determine the role of the fistula characteristics on the outcomes of repair in urethrocutaneous fistulas that develop after hypospadias surgery. METHODS A total of 160 patients who had undergone urethrocutaneous fistula repair after hypospadias surgery were enrolled in this study. The prognostic significance of the site, size, and number of fistulas, number of the previous operations, and the techniques applied were analyzed by the appropriate statistical methods as the parameters of the study. RESULTS The fistulas were localized at the distal, mid, or proximal penile region in 69 (43.2%), 60 (37.5%), and 31 (19.2%) patients, respectively. No statistically significant relation was found between the fistula site and the success rate (P >0.05). The fistula size (2 mm or less versus greater than 2 mm) and the number of fistula repairs (single versus two or more) also did not affect the outcome (P >0.05, Pearson chi-square and Fisher's exact tests). CONCLUSIONS The site, size, and number of the fistula repair seemed to have no impact on the success rate. Well-known aspects of the modern hypospadias surgery (eg, delicate tissue handling, instruments, point coagulation, and vascularity of the tissues) probably play a role in the outcome.

Abstract
The purpose of this study is to compare primary repair procedure with those that use bio-concordant materials in the treatment of urethrocutaneous fistula. Twenty-five New Zealand rabbits were randomly placed into five groups (primary repair, free graft, allograft fascia lata, alloderm and bovine pericardium repair groups). A single dose of 20 mg/kg of ceftriaxon was applied intramuscularly as a prophylactic dose. Urethrocutaneous fistula was formed on midpenile level. Later, while primary repair was applied in one group, repair with free grafts and with other bio-concordant materials were performed in other groups. Urinary diversion was not used in any of the rabbits. The macroscopic observation was evaluated with urethrography obtained 21 days after the operation and then the rabbits were sacrificed. A total point was obtained by awarding a point to each good parameter in the histopathological evaluation and all the groups were compared. The urethrographic findings and macroscopic examinations were normal in all groups. In histopathological examinations, ranging from the best to worst results, bovine pericardium group (8 points) had a better total score than primary repair group (7 points), allograft fascia lata group (7 points) and alloderm group (7 points). The free graft group had the worst total point (6 points). Bio-concordant materials can be used in urethrocutaneous fistula repair as an alternative to primary repair or to the grafts obtained from body tissues.

Abstract
OBJECTIVE Hypospadias is an increasingly common condition, and many procedures have been described for operative correction. We reviewed our experience of different techniques of one-stage hypospadias repair. MATERIALS AND METHODS We retrospectively reviewed 107 hypospadic boys who were younger than 15 years between January 1986 and June 2003. We included all patients who underwent one-stage hypospadias repair. All patients were evaluated for age, type of hypospadias, associated anomalies, surgical technique, and morbidity rate. The functional and cosmetic results were evaluated at 1 month, 6 months and 1 year postoperatively. Univariate analysis was done to identify those variables that might serve as interdependent predictors of postoperative complications. RESULTS The median age was 7 years (6 months to 13 years). Severe chordee was observed in 15 patients. The majority of cases were anterior hypospadias (53%), while the majority of complications were observed in the middle group (62%). Cosmetic and functional results were satisfactory in the majority of the patients. Complications included 16 fistulae (15%) and 11 meatal stenoses (10%). Some prognostic factors such as age, insertion of a suprapubic cystostomy tube, suture structure, and time of catheter removal did not significantly affect the risk of complication, whereas some other factors such as associated anomalies, severe chordee, middle and posterior hypospadias, and use of a pedicle island flap were significant in their relation to the complication rate. CONCLUSION Such possible risk factors as severe chordee, middle and posterior localized hypospadias, and use of a pedicle island flap may increase the postoperative complication rate. There is no gold-standard technique for hypospadias repair; the procedure of choice should depend on the individual anatomy of the penis. The long-term outcome after puberty has to be awaited.
