Afr J Paediatr Surg 2024; 21:111-116. [PMID: 38546249 PMCID: PMC11003566 DOI: 10.4103/ajps.ajps_107_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 10/03/2022] [Accepted: 01/02/2023] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Hypospadias is a wide-world congenital malformation that accounts for 1 of 300 live male births. Many procedures were considered for its management. As the tubularised incised plate (TIP) urethroplasty, the most prevalent technique, caused many complications, several modifications were applied to the original operation to improve the outcomes and alleviate complications. The aim of this study was to compare the outcome of the ordinary TIP urethroplasty with the technique modified without dissection of the glans penis. MATERIALS AND METHODS A total of 82 patients with a mean age of 18.8 (±14.8) months, were randomly assigned to undergo TIP with either complete glans wings mobilisation (Group A, n = 42 patients) or without glans dissection (Group B, n = 40 patients). To evaluate the effect of modified TIP urethroplasty without glanular dissection for treatment of distal hypospadias in contrast to classical TIP repair. RESULTS Both techniques showed similar outcomes regarding functional repair, with good to excellent results between 88% and 90% after 6 months of follow-up. Most confronted post-operative complications were wound infection, oedema, urethrocutaneous fistulas and meatal stenosis. Less frequently haematoma, post-operative bleeding and glans dehiscence were encountered. The differences in complication rates between the two studied groups were statistically insignificant except for oedema (P = 0.04), and need for urethral dilatation (P = 0.002) that were more prevalent among patients who were treated with classic TIP repair with complete glans wings mobilisation. CONCLUSION From our point of view, it seems that TIP without glanular dissection technique does not outweigh TIP with complete glans wings mobilisation regarding functional outcomes and post-operative complications.

Abstract
Purpose This study aimed to report the outcomes of hypospadias repair performed at a tertiary-level hospital during 2018 to 2021. Methods A retrospective chart review of 119 patients was performed. Results The most frequent coronal hypospadias cases were distal. However, the most common scrotal hypospadias cases were proximal. The average age at the time of the first surgery was 2.4 years (standard deviation, ±2.3 years). The tubularised incised plate technique was performed for 57 of these 119 patients. Urethral fistula was the most common complication associated with distal and proximal cases (23.96% and 30.43%, respectively). No significant correlation was observed between any complication and the surgical technique. Based on the logistic regression model, the duration of urethral stenting was statistically significant (p=0.025), indicating that a urinary catheter duration of more than 5 days resulted in a 2.9-times increased risk of postoperative urethral fistula. Conclusion Prolonged urethral stenting for more than 5 days may result in subsequent urethral fistula development. Neither the severity of hypospadias nor the surgical technique seems to affect postoperative complications.

Abstract
BACKGROUND Surgical repair of hypospadias deformity is a challenging and complex issue. However, the technique of Snodgrass and its modifications attend promising functional and cosmetic results. PURPOSE To assess the Lembert suturing technique effectiveness as a modification of the Snodgrass technique in lowering an urethrocutanous fistula rate. PATIENTS AND METHODS Fifty boys with mid-shaft and distal hypospadias were repaired using the modified Snodgrass technique utilizing the interrupted Lembert suturing technique in neourethroplasty. Patients with previous failed operations or severe chordee were excluded from the study. RESULTS None of the patients develops UCF apart from one who developed complete wound dehiscence following severe wound infection. Mild meatal stenosis is seen in two patients, and one patient experienced a small area of superficial skin sloughing.

Abstract
Abstract
Background
Several preoperative factors affect the outcome of Tabularized Incised Plate (TIP) repair. Our aim was to collect and analyze all these factors to define what the most important predictive factors are.
Methods
Hundred patients (1–5 years old) with primary distal hypospadias were included. Exclusion criteria included previous penile operations and hormonal treatment or associated congenital anomalies. Anogenital distance (AGD), stretched penile length (SPL), meatal site, glanular shape, chordee and torsion degree, plate width and glans meatus shaft (GMS) score were assessed. TIP repair was done to all patients and followed up for one year. The outcome was correlated with the above parameters.
Results
Mean ± SD of age of patients was 3.5 ± 1.5 years, while weight was 14.1 ± 3.0 kg. Complication rate was 18% including urethrocutaneous fistula (UCF) and meatal stenosis 14%, repair breakdown 1% and urethral stricture 3%. Patients with chordee degree < 30° and distal penile meatal location were associated with increased risk for complications by 11.6 and 8.2 times; 95% CI was (1.46–91.75) and (1.02–66.52), respectively (p < 0.05 for each). Plate width ≥ 9 mm, AGD > 5 cm, GMS score ≤ 7 (p < 0.001 for each), age of patient ≤ 2 years old, and SPL > 3.5 cm (p < 0.01 for each) were associated with successful outcome of repair.
Conclusion
The proposed successful criteria of TIP repair were absent chordee, coronal/subcoronal penile meatal location, plate width ≥ 9 mm, AGD > 5 cm, age of patient ≤ 2 years old, GMS score ≤ 7, SPL > 3.5 cm and grooved glanular shape.

Abstract
Abstract
Background
To compare the outcomes between classic tubularized incised plate (C-TIP), known as Snodgrass urethroplasty, and grafted TIP (G-TIP) in the repair of primary distal penile hypospadias.
Methods
Parents of all children presented to our tertiary care institution with primary distal penile hypospadias were asked to participate in this study. Patients were equally randomized using closed envelope method into two groups; Group A underwent repair using G-TIP and Group B underwent repair using the C-TIP. Circumcised cases and/or cases with penile chordee > 30 degrees were excluded from this study. Urethral catheter was kept for 7 to 10 days after surgery. The success rate and cosmetic outcomes assessed by HOSE score were evaluated at 6-month postoperatively.
Results
A total of 55 patients were recruited in each group. One hundred and seven patients of the 110 patients (54 and 53 in groups A and B, respectively) were evaluated at 6-month postoperatively using HOSE score. All preoperative data were comparable in both groups. Success was documented in 49/54 patients (90.7%) in group A. The five failures were secondary to two cases of glans dehiscence and three cases of residual postoperative chordee. Whereas, success was documented in 48/53 patients (90.5%) in group B. Complications were: a case of meatal stenosis, three cases of fistula, and a case of combined meatal stenosis and fistula. The HOSE score was comparable between the two groups (15.4 ± 1.09 vs. 15.6 ± 0.55; p = 0.29). However, the operative time was statistically longer in the G-TIP compared with the C-TIP (91.4 ± 6.2 min vs. 85.2 ± 6.3 min; p < 0.001), respectively.
Conclusion
The G-TIP urethroplasty provided comparable results with C-TIP in terms of cosmoses, success rate, and complications. However, G-TIP was accompanied with significantly longer operative time.

Abstract
INTRODUCTION Long-term complication rates after distal hypospadias repair can be close to 20%. There are no available guidelines regarding the need for a catheter in distal urethroplasty. We report a retrospective analysis on medium-term redo-urethroplasty rate and cosmetic results after a two-years pilot study on stented/un-stented distal urethroplasties. MATERIALS AND METHODS A total of 11 stented (Group A) and 17 un-stented (Group B) Snodgrass-procedures were performed by the same pediatric surgeon at our Institution (2011-2013). The median age at surgery was 2.1 years (range 1-8.5). Inclusion criteria were primitive distal defect, same surgeon in both interventions, catheter-free discharge. The median follow-up was 6.4 years (range 1.5-8.1). All patients received at least one post-operative clinical-cosmetic examination (HOSE). The aim of our study was to compare medium-term complications and redo-urethroplasty rates before starting a randomized study. A retrospective analysis was performed. We used Fisher's exact-test (P < 0.05) for statistical analysis. RESULTS Of 28 complications, 5 required redo-surgery: 2/11 stented-cases, 3/17 un-stented. Cosmetic results were satisfactory in both groups. These results were not statistically significant (P = 1.000). CONCLUSION Long-term follow-up is mandatory to know redo-urethroplasty rate and cosmetic outcome after distal stented/un-stented repair. Further studies are needed to evaluate the role of catheter placement and the definitive outcome in distal urethroplasty.

Abstract
BACKGROUND Hypospadias is a common congenital anomaly which is determined as an abnormal urethral opening on the ventral face of penis. The purpose of this rat model study was to research the effect of topically applied Aloe vera after a tubularized incised plate urethroplasty (TIPU). METHODS The TIPU model was applied to male Wistar albino rats. A total of 30 rats were randomly grouped into 3 groups of 10. Group I was assigned as the control group, treated with 0.9% saline only twice a day for 15 days. Group II received topical Aloe vera gel once a day and Group III received Aloe vera gel twice a day. Spongiofibrosis was graded as 0: none, 1+:≤10% tissues involved, 2+:10%-49% tissues involved, 3+: ≥ 50% tissues involved. RESULTS A higher degree of fibrosis and inflammation was determined in the Group I subjects than in Groups II and III. Fibrosis of grade 3+ was observed in 33% of the control group and not in any of the two Aloe groups (p = 0.043). Inflammation of grade 3+ was seen in 66.7% of the control group, in 10% of Group II, and in 33% of Group III (p = 0.02). CONCLUSIONS The topical application of Aloe vera to a surgically created tubularized incised plate urethroplasty model decreased inflammation and fibrosis that may affect the success rates of this operation.

Abstract
INTRODUCTION Hypospadias is one of the most common anomalies of male external genitalia. The aim of hypospadias repair is to achieve a normal phallus with a satisfactory functional and cosmetic result and to develop a single and consistent urinary stream while in standing position. The introduction of tubularized incised plate (TIP) urethroplasty by Snodgrass in 1994 resulted in revolutionizing management of different types of hypospadias. While there is consensus on the use of absorbable sutures in hypospadias repair, there are no specific guidelines for the suturing technique and the technique itself remains debatable. OBJECTIVE To compare the outcome of interrupted- and continuous-suture in hypospadias repair using TIP technique. STUDY DESIGN This was a prospective randomized study. It comprised 260 uncircumcised hypospadiac boys with adequate urethral plate who underwent TIP repair. Boys with glanular, recurrent, proximal hypospadias and inadequate urethral plate were excluded from the study. The boys were randomized into two groups: Group A consisted of 130 boys who underwent TIP repair using continuous subcuticular suture urethroplasty and Group B of 130 boys who underwent TIP repair using interrupted subcuticular suture urethroplasty. RESULTS The operative time was of lower statistical significance in group A (P = 0.006) while the rate of complications were of higher statistical significance in group A (P = 0.027). Urethrocutaneous fistulae occurred in 20 patients (14 in Group A and six in Group B), which is a statistically significant difference (P = 0.048). On the other hand, superficial wound infection, partial glans dehiscence, meatal stenosis, urethral stricture, and aesthetic appearance were statistically insignificant. DISCUSSION AND CONCLUSION The effect of suturing techniques in bowel anastomosis has been studied and it has been found that the use of an interrupted-suturing technique results in a decreased complication rate compared to continuous suturing. This agrees with our study where the running sutures groups was associated with a higher complication rate compared to interrupted sutures.

Abstract
Background Previous reports found that a preincision urethral plate (UP) width <8 mm increased the occurrence of urethroplasty complications (UCs) in tubularized incised plate (TIP) hypospadias repair. However, is the classification of the UP width based on an 8 mm cut-off value to predict the outcome of TIP urethroplasty objective enough or universally applicable? The purpose of our study was to assess the effect of the UP width on the outcomes of TIP hypospadias repair in the Eastern population we served. Methods We retrospectively reviewed the records of patients who underwent TIP hypospadias repair by the same surgeon between August 2013 and December 2019 in our hospital. Data were collected, including demographics, intrinsic parameters of the penis, surgical parameters and subsequent surgical outcomes. The data were analyzed and the cut-off value of the UP width was calculated using a receiving-operator curve. Results Primary TIP urethroplasty was carried out in 116 patients with a mean age of 35.89±29.40 months. The meatal location was distal in 49 patients, midshaft in 56 patients and proximal in 11 patients. The mean glans width was 12.28±1.36 mm, the mean UP width was 5.74±1.37 mm, the mean neourethral length was 1.96±1.32 cm, and the mean operation duration was 87.52±11.47 min. During a median follow-up of 42 (range: 6 to 80) months, UCs developed in 12 patients, and the UP width was significantly related to the occurrence of UCs (P=0.014). According to the 6 mm cut-off value of the UP width by the receiver operating characteristic curve, patients were divided into two groups. Group A (UP width ≥6 mm) included 69 patients, and Group B (UP width <6 mm), 47 patients. UCs occurred in 3 patients in Group A vs. 9 patients in Group B, P=0.010. Conclusions UP width is a potential risk factor for UCs after TIP hypospadias repair. Using this technique with an UP width ≥6 mm is sufficient to result in a good outcome of hypospadias repair.

Abstract
Objectives: To our knowledge, the incidence of congenital meatal abnormalities associated with hypospadias varies from 9.6% to 31%, of which meatal stenosis is the most common, affecting 9.1–16.7% of patients. Traditionally, meatal stenosis has been dealt with by meatal dilatation, although ventral meatotomy until the normal urethra is encountered has also been used. Here, we report the outcome of a technique where, during hypospadias repair, a dorsal midline incision was performed instead of a ventral urethral incision, starting at the narrow meatus and subsequently extending proximally to treat the meatal stenosis. Methods: Patients having distal hypospadias with meatal stenosis were included in this study. In this technique, a dorsal midline incision was extended until normal calibre urethra was encountered. Patients with chordee >15°, proximal hypospadias, redo cases, glans width <14 mm, where separation of the skin from the underlying urethra was not possible and with a follow-up of less than three months were excluded from the study. A total of 73 patients were operated on using this technique. Results were assessed with regards to urethrocutaneous fistula (UCF) and stricture formation. Results: Five (6.85%) patients developed UCF: one (5%) in the subcoronal group, two (8.0%) in the distal penile group and two (14.3%) in the mid-penile hypospadias group. Postoperatively, only one patient had meatal stenosis. Conclusion: We think hypospadiac meatal stenosis is best treated by a dorsal midline incision, as it does not lead to a proximal shift of the meatus, and this defect heals by re-epithelisation without significant scarring, which in turn decreases the possibility of UCF. That is why the fistula rate in our study was 6.85%, which is lower than in various published series.

Braga LH, McGrath M, Farrokhyar F. Dorsal penile block versus caudal epidural anesthesia effect on complications post-hypospadias repair: Dilemmas, damned dilemmas and statistics. J Pediatr Urol 2020; 16:708-711. [PMID: 32900635 DOI: 10.1016/j.jpurol.2020.08.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Revised: 08/07/2020] [Accepted: 08/12/2020] [Indexed: 10/23/2022]
Abstract
The evidence examining the effects of regional blocks on complications posthypospadias repair has been controversial. Nine observational studies have been published thus far, with inconsistent and somewhat contradictory results. In this educational article, we attempt to explain the concepts of study accuracy and precision in the context of the hypospadias literature to shed some light on the reasons behind those controversies. Methodological issues such as selection bias, confounding effect, sample size, confidence interval and study generalizability from studies involving dorsal penile block versus caudal epidural anesthesia in hypospadias repair are discussed.

Abstract
Abstract
Background
The assessment of a child having hypospadias with chordee/ventral curvature (VC) and meatal position that appears to be proximal/mid-penile can be challenging with regard to the choice of chordee correction and type of urethroplasty. The feasibility of preservation of native urethral plate is dependent on these choices. Classically, urethral plate resection of the corpora is performed to correct severe VC, whenever VC is presumed to be due to short urethral plate. But VC is seen to persist in many such cases, in spite of this maneuver that commits the patient to a more complex reconstruction. The aim of the study was to analyze the variation in preoperative and intraoperative assessment of proximal and mid-penile hypospadias, with respect to severity and possible surgical options, in patients treated by a standard protocol of sequential and anatomical approach to repair. The other objective was to ascertain if “extensive ventral urethral detethering” (in all cases) and “urethral plate augmentation” (in select cases) could facilitate more anatomical repair in these cases, with urethral plate preservation and utilization for repair wherever feasible.
Results
Fifty-two children who underwent the specific protocol of repair during the 5-year period from January 2014 to December 2018 at a tertiary teaching institution were included in the study. The essential principles adopted for the surgery were as follows: (i) urethral plate preservation in all possible situations; (ii) “extensive ventral urethral detethering” up to the bulb, as a preliminary step, (iii) sequential correction of VC with urethral plate augmentation (in select cases); and (iv) selecting the optimal repair based on the following principles: (a) urethral plate tubularization, (b) urethral plate augmentation, and (c) urethral plate substitution. There was considerable difference in the preoperative and intraoperative assessment of meatal position, with 12 of the apparently mid-penile hypospadias being reclassified as distal penile after preliminary dissection. Three of the penoscrotal variants were regrouped as proximal penile and 6 of the proximal penile were regrouped as mid-penile type. Majority of cases which were deemed to require complex reconstruction on preoperative assessment could be treated by a single-stage procedure.
Conclusion
The meatal position is seen to shift distally in select cases of proximal or mid-penile hypospadias after thorough degloving, dartos release, and detethering of Buck’s fascia over ventral urethra. Urethral plate can be preserved for utilization in repair in many of these cases by augmenting the urethral plate, enabling a more anatomical neourethral reconstruction. Resection of urethral plate can be thus restricted to the most severe cases of VC.

Abstract
Background: There is a lack of consensus regarding the role of oral antibiotics following hypospadias repair. Objectives: The study aimed to evaluate the role of oral antibiotic use following stented Tubularized incised plate urethroplasty (TIPU) in the prevention of bacteriuria and urinary tract infections (UTIs). Methods: A prospective study was conducted on 40 patients undergoing stented TIPU for coronal hypospadias between January 2014 and December 2016. The average age of the subjects was 13.2 months at the time of surgery, ranging from 11 to 16 months. The patients were divided into two groups. Group A consisted of 20 patients receiving oral antibiotics until urethral catheter removal, whereas group B consisted of 20 patients without any oral antibiotics postoperatively. Results: The two groups were followed for three years. The urethral catheter was removed eight days postoperatively in the two groups. In group A, the patients received oral antibiotics as long as the catheter was left in situ. Urine samples were collected from the patients and sent for analysis and culture at the time of stent removal and after three weeks. The results showed that 3/20 (15%) patients from group A had pyuria and bacteriuria, while all of them had negative urine culture results. On the other hand, in group B, 8/20 (40%) patients had pyuria and bacteriuria (P > 0.05), and four (20.0%) patients had positive urine cultures for Escherichia coli (P < 0.05), sensitive to co-trimoxazole. None of the patients in the two groups had febrile UTI. Conclusions: The use of oral antibiotics for patients following stented TIPU reduces pyuria and significantly decreases positive urine culture results and the risk of UTI after surgery.

Abstract
BACKGROUND The paradigm for hypospadias repair is a straight penis with a vertical meatus at the tip of the glans that provides satisfactory urination and is cosmetically acceptable to the parents of the patient. OBJECTIVE To determine the cosmetic and functional outcomes of hypospadias repair in relation to the width of the urethral plate. PATIENTS AND METHODS This study was a prospective evaluation of patients operated for hypospadias. The urethral plate width (UPW) of the patients were measured preoperatively using vernier calipers. The patients were categorized into groups A and B. Group A patients have a UPW <8 mm, whereas group B patients have a UPW ≥8 mm. The width of the urethral plate was correlated to the cosmetic outcome (using hypospadias objective penile evaluation [HOPE]) and functional outcome (using the urinary stream) of hypospadias repair. RESULTS Overall, 47 patients had their hypospadias repaired during the study period. But, only 42 patients who had their distal hypospadias repaired using tubularized incised plate urethroplasty were evaluated. There were 20 patients (47.6%) in group A and 22 patients (52.4%) in group B, with a mean urethral plate of 7.3 mm ± 0.50 SD. The mean UPW in group A was 5.6 mm ± 1.22 SD and the mean UPW in group B was 8.8 mm ± 0.88 SD. Overall, mean HOPE score was 40.0 ± 6.83 SD. Group A patients had a mean HOPE score of 38.7 ± 7.49 SD, whereas Group B patients had a mean HOPE score of 41.2 ± 6.08 SD. P-value was 0.725, which is not statistically significant. Relating good urinary stream (15 in group A and 20 in group B) with the width of the urethral plate statistically (using Spearman correlation technique) gave a P-value of 0.03 (P < 0.05), which is statistically significant. CONCLUSION Our findings indicate that the cosmetic outcome of hypospadias repair may not be determined by UPW, but the functional outcome may be predicted by the width of the urethral plate.

Abstract
BACKGROUND Hypospadias is one of the most common congenital disorders of the urogenital system that is repaired by surgical method. Literature review shows that silicone gel is effective in preventing and improving hypertrophic scars after surgery. Thus, we conducted this study to evaluate the effect of silicone gel on scar reduction after surgical repair of hypospadias. MATERIALS AND METHODS In this randomized double-blind clinical trial, 64 patients who had undergone surgical repair of hypospadias were divided into two groups: 32 patients in the intervention group (silicone gel) and 32 in the control group (placebo). Then, the patients in the silicone gel treatment group were treated twice per day for two months on the site of surgical wound, and the patients in the control group were treated with Vaseline twice per day for two months on the site of surgical wound, too. Scar characteristics (pigmentation, vascularity, pliability, and height) were recorded based on Vancouver's scars scale. Finally, the results of the two treatments on reduction of scars after surgical repair were compared between the two groups. Data were analyzed using SPSS-24. RESULTS There were significant differences between the two groups in scar characteristics after surgical repair of hypospadias, such as vascularity, pliability, and height (P˂0.05); however, there was no significant difference in pigmentation (P>0.05). CONCLUSION The results of this study showed that silicone gel had considerable effects on reduction of scars after surgical repair of hypospadias. However, further studies with larger sample size are recommended to confirm our conclusion.

Abstract
Purpose: In severe hypospadias staged repair is commonly used and it is regarded as feasible, safe, and durable. In this article we want to describe the results of a modification of the staged repair: a midline incision of the graft during the second stage. Materials and Methods: This is a consecutive single team (2 surgeons) retrospective series. Between 2014 and 2017, 250 patients underwent hypospadias repair, among them 35 patients that had primary staged hypospadias surgery with completed first and second stage repair. 24 (68.6%) cases received a preputial skin graft and 11 (31.4%) buccal mucosa graft. Median age at first stage was 1.5 (0.5-22.1) years, mean time between first and second stage operation was 0.72 (0.4-1.76) years. Follow up rate was 100%, mean follow up period was 1.50 (0.4-3.8) years. Results: The total complication rate was 22.9%. In buccal mucosa repair the complication rate was 36.4% and in preputial graft repair the complication rate was 16.7%, respectively. In 23 patients (65.7%) during second stage urethroplasty a midline incision was performed (8 glandular graft, 15 penile graft, 6 at level of urethral opening). Complication rate in non-incised urethroplasty was 8.3%, in incision at glandular level 37.5%, in incision at penile level 13.3% and in incision at urethral opening 16.7%, respectively. Conclusions: Two stage repair is the method of choice in the correction of severe hypospadias. In selected cases a midline incision of the graft is feasible and can be applied if needed. Randomized studies will be needed to evaluate the true benefit of incising the graft.

Abstract
This case series of 51 patients (age range = 11-17 years; 30-month follow-up) describes a new modified approach to treatment of distal and mid-penile hypospadias that has fewer complications. The meatal locations were sub-coronal (51%), coronal (45%) and mid-penile (4%). Forty patients had chordee. Urethra with the corpus spongiosum was dissected off the corpus cavernosum up to the peno-scrotal junction. The distal 5 mm stenotic and avascular part of the urethral tube was excised. The elastic urethra was then stretched and sutured to form a neo-meatus. The urethra was anchored to the Buck's fascia at the glandular, sub-coronal and mid-penile levels. Meatal regression in one patient (2%), subcutaneous hematomas in two patients (4%) and wound dehiscence in two patients (4%) were the complications in the immediate postoperative period. None developed fistula, meatal stenosis or residual chordee in the 30-month follow-up.

Abstract
BACKGROUND Hypospadias is one of the most common congenital abnormalities in childhood. The number of cases has rapidly grown in recent years. OBJECTIVES The purpose of this research was to analyze the histological and morphological differences of the foreskin samples taken from boys in three age groups. STUDY DESIGN A total of 30 Asian patients participated in the research. Clinical materials obtained via biopsy were divided into three age groups. The first group included 10 biopsy materials of preputial skin taken from boys aged <3 years. The second included 10 similar biopsy materials from boys aged 3-5 years. The third included 10 biopsy materials taken from boys aged 5-7 years. The skin areas were taken from the dorsal, two lateral and the ventral surfaces (closer to the bridle) with dimensions of 1.0 × 1.0 cm. All removed foreskins underwent histological examination. RESULTS Obtained results showed that the number of vein clusters in the prepuce and the cases of vessel wall fibrosis grew with age. It is worth noting that no such discoveries were made in younger boys (aged <3 years). Sample analysis showed that the number of nerve, vessel, and collagen fibers increased with age. DISCUSSION It is believed that it is important to continue investigating the prepuce in hypospadias, in order to gain a better understanding of the abnormality depending on type. CONCLUSION Peculiarities of prepuce in hypospadias discovered in different age groups allowed a full understanding of the pathology development processes.

Abstract
INTRODUCTION Observational studies, particularly case series, represent the majority of the current hypospadias research. As a result, this literature lacks standardization of surgical techniques, uniform definitions of hypospadias complications, and consistency of outcome reporting, which may make it difficult to compare results across studies. A modified version of the STROBE statement, containing 20 items, was presented at the International Pediatric Urology Task Force on Hypospadias meeting to assist with clear and transparent reporting of hypospadias studies. The adoption and implementation of this modified tool will allow investigators and health care providers to critically evaluate quality and identify bias within the literature. In addition this instrument will ensure consistency of reporting, improving objective comparisons between studies, unification of results, and development of evidence-based clinical guidelines. METHODS In this article, we have applied the modified STROBE statement to the hypospadias literature, aiming to create a guide on study reporting for pediatric urologists, and ultimately improve the quality of research in our field. We present itemized recommendations for adequate reporting of hypospadias studies and case series, ranging from drafting the abstract to addressing biases and potential sources of confounding. Included with each item is a brief explanation of its importance and potential effect on the study, as well as pertinent examples of hypospadias articles. RESULTS A modified STROBE summary table containing 20 items is presented in (Supplementary Table 1). CONCLUSIONS If properly conducted and reported, hypospadias studies have the potential to provide useful information to clinicians and surgeons. However, authors should recognize the inherent limitations of these observational studies, especially in the form of bias, which may introduce invalid data or limit generalizability. Thus, we expect that the use of this guiding tool will not only improve transparency of hypospadias reporting, but also improve its methodological quality, allowing proper comparison and interpretation of data across different institutions.

Abstract
Objective Snodgrass urethroplasty remains the preferred technique in primary distal hypospadias but development of meatal stenosis often limits distal extension of the midline incision of the urethral plate (MIUP), which remains a limiting factor in reconstructing an apical neomeatus (NM). We here-in assess the cosmetic and functional outcome with distal extension of the MIUP in grafted tubularised incised-plate urethroplasty (G-TIP) repair. Patients and methods This prospective study included the surgical experience of 263 cases of primary hypospadias operated upon between 2012 and 2015. The G-TIP technique included standard steps of Snodgrass urethroplasty, including degloving and harvesting of glans wings, followed by MIUP that was extended distally beyond the margins of the urethral plate (UP) into the glans. The incised bed was grafted with a free preputial skin graft and fixed to the bed with polydioxanone 7-0 suture. The UP was tubularised and the suture line reinforced with a Dartos flap. The urethral catheter was removed at 7–10 days after the repair and the outcome was assessed at follow-up using the Hypospadias Objective Scoring Evaluation (HOSE) system. Results An apical NM was achieved in 96% of the patients with a 3.7% incidence of urethrocutaneous fistula. The presence of suture tracks and graft at the margins of the NM were seen in the initial 4% and 5% of cases, respectively. Acceptable cosmetic results, with objective HOSE scores of >14, were achieved in 96% of cases. Conclusion The G-TIP repair is a straightforward and feasible technique facilitating reconstruction of an apical NM, with an optimum outcome based on HOSE scoring. However, multicentre data are needed for undertaking comparative analysis and to assess the universal applicability of this technique in primary hypospadias.

Abstract
Hypospadias surgery is a humbling art form. The evolution of surgical techniques has made distal hypospadias outcomes favorable, but recent publications suggest that our complication rates for proximal hypospadias are much higher than previously reported. To explain these shortcomings, we examine the literature and focus on the lack of standardized documentation, the subsequent inability to objectify the severity of the phenotype, and the underestimation of complications due to lack of long-term follow up. The variability in surgical technique and the fact that the literature abounds with small case series from single institutions also limits our ability to compare outcomes. We believe that the use of standardized and scored phenotype assessments from diagnosis through the extended postoperative period will allow for improved scientific assessment of outcomes. This will facilitate multi-institution collaboration and tabulation of outcomes, allowing rapid data accumulation and assessment for this rare disorder. As surgeons, we must follow boys through puberty into adulthood and must honestly report our results in order to advance our surgical approach to this complicated problem.

Abstract
PURPOSE Tubularized incised plate urethroplasty (TIPU) is the preferred surgical option for distal and mid-shaft hypospadias repair. Neourethra dartos flap coverage is routinely used as a protective layer with good results. We modified meatus-based ventral dartos flap (MBVDF) to TIPU by dissecting the proximal mid-ventral dartos attached urethra and leaving the subcutaneous fascia connecting the meatus, and retrospectively compared the outcomes of using MBVDF with single dorsal dartos flap (DDF) on the complication rates of TIPU. METHODS We present 2 surgeons' experiences with 356 patients with distal and mid-shaft hypospadias between January 2010 and December 2014. Patients were divided into two groups. Group DDF included 185 patients (mean age 29 months) underwent TIPU with DDF rotated laterally covering the suture lines of the neourethra. Group MBVDF included 171 patients (mean age 26 months) underwent TIPU with MBVDF covering the suture lines of the neourethra. Statistical analysis of patient basic information and complications was performed by two independent sample t test and Chi square test or Fisher's exact test. RESULTS There were no statistical differences in age, type of hypospadias, and follow-up time between the two groups. The mean operative time in the group MBVDF (68.93 ± 8.32 min) was significantly shorter than in the group DDF (73.60 ± 9.06 min). Ventral skin necrosis (2.7%) and penile rotation (3.8%) in group DDF was significantly higher than group MBVDF which did not occur. The differences in other complication rates including fistula rate (2.7 vs 2.9%) between the groups were not statistically significant. CONCLUSION DDF and MBVDF with TIPU are similarly effective methods for decreasing fistula in hypospadias repair. MBVDF with TIPU may be an easier method and can avoid ventral skin necrosis and penile rotation.

Abstract
BACKGROUND Over 300 different operations have been described for the management of hypospadias. In recent times, the numbers of operations used in various centres have gradually reduced as the principles necessary to ensure adequate cosmetic and functional results with minimum complications are better understood. The aim of this article was to review the different types of operations used for managing hypospadias in a tertiary hospital in a developing country, to analyse the complications of surgery and discuss the factors that contribute to complications. MATERIALS AND METHODS Patient folders, theatre, and ward records were used to obtain the required information. The age at surgery, types of hypospadias at presentation, types of operations done and complications were analysed. RESULTS AND CONCLUSION With three main types of operations, tubularised incised plate urethroplasty and meatal advancement and glanuloplasty incorporated for anterior hypospadias (glanular, coronal, subcoronal, distal, midpenile), and lateral based flap urethroplasty for posterior hypospadias (proximal penile, penoscrotal, scrotal, perineal), most hypospadias were corrected with acceptable complication rates.

Ahmed M, Alsaid A. Is combined inner preputial inlay graft with tubularized incised plate in hypospadias repair worth doing? J Pediatr Urol 2015; 11:229.e1-4.

Abstract
BACKGROUND It has been noted that after tubularized incised plate urethroplasty (TIP) repair, the final meatal position is glanular but not at the optimum position. Inner preputial inlay graft combined with tubularized incised plate (G-TIP) has been proposed for redo urethroplasty. We extended this indication to be the standard technique for primary hypospadias repair. We conduct this prospective study to obtain a wide, slit-like appearance neomeatus at the optimum position in the glans proper and to judge if hypospadias repair complications differ from TIP repair in the published data in the literature. PATIENTS AND METHODS This prospective study included 230 consecutive patients who underwent this technique. The study was conducted from November 2011 to August 2014 for all hypospadias cases to be repaired in a single stage regardless of the width and depth of urethral plate or the glans size and shape. Localization of the meatus was glanular in 13 patients, coronal in 75, distal penile in 112, mid penile in 25 and proximal in five. The urethral plate was incised deeply and extended distally beyond the end of the plate by 3 mm in glans proper. The mucosal graft was harvested from the inner prepuce, inlayed and quilted in the incised urethral plate. The neourethra was created over a urethral catheter in two layers. The vascular dartos flap was mobilized dorsally and moved ventrally to cover the neourethral suture line as a barrier. RESULTS The follow-up period ranged from 5 to 36 months. Excellent cosmetic and functional results were achieved in 221 of 230 patients (96.09%). Neither meatal stenosis nor urethral diverticulum were encountered. An excellent glanular position of a wide slit-like neomeatus was achieved using this technique. Nine patients (3.91%) developed urethrocutaneous fistula. Excellent urinary stream was reported by parents. CONCLUSIONS Combined inner preputial graft with TIP urethroplasty secures the optimal glanular position of a wide slit-like neomeatus because of extension of the incision beyond the end of the plate, thus optimizing functional and cosmetic outcome with no meatal stenosis.

Abstract
INTRODUCTION Surgery for hypospadias has been continuously evolving, implying thereby that no single technique is perfect and suitable for all types of hypospadias. Snodgrass technique is presently the most common surgical procedure performed for hypospadias. MATERIALS AND METHODS We analysed the results of tunica vaginalis flap (TVF) as an additional cover to the tubularised incised plate (TIP) repair. RESULTS A total of 35 patients of hypospadias were repaired using TIP urethroplasty and TVF as a second layer. Mean age at the time of presentation was 6.63 ± 3.4 years. Post-operative complications namely wound infection, flap necrosis, scrotal haematoma, scrotal abscess, urethral fistula, meatal stenosis were recorded and analysed during follow-up period. Need for re-do surgery was considered as failure of the operative procedure. Out of 35 patients, 8 (22.85%) patients had proximal penile hypospadias and 27 (77.14%) patients had distal penile hypospadias. Mean post-operative follow-up was 24.53 months. During the follow-up complications noticed included wound infection (n = 2), urethrocutaneous fistula (n = 1) and meatal stenosis (n = 1). Wound infection was managed with appropriate antibiotics as per hospital policy/culture and sensitivity reports. Meatal stenosis responded to bougie dilatation/calibration during follow-up. CONCLUSION To conclude, TVF as an additional cover is associated with an acceptable complication rate and good cosmetic results if performed with meticulous tissue handling.

Abstract
Objectives. To review cases of hypospadias that were repaired with TIPU method and consequently resulted in the necrosis of ventral penile skin flaps. Methods. Eighty-three patients with hypospadias underwent TIPU procedure by two surgeons. Neourethra in all patients was covered with dartos flap prepared from the preputium or penile shaft. In cases where ventral skin could not be covered primarily, closure was ensured by using preputial Ombredanne or Byars' flaps to repair ventral defects. Results. The median age of patients was 4 years. Twenty-five (30.12%) patients that underwent hypospadias repair had urethral opening at the coronal level, 33 (39.75%) at the distal penis, 10 (12.04%) at the midpenis, and 15 (18.07%) at the proximal penis. The ventral skin defect could not be primarily covered in 10 patients with penile shaft hypospadias. Consequently, Byars' method was used in 8 of these patients to cover the defect and the Ombredanne method was used in the remaining 2. Ventral skin flap necrosis developed in 5 patients (4 Byars and 1 Ombredanne). It was medically treated in 4 patients. Urethral fistula developed in the other patient whose necrosis was deeper. The mean hospital stay was 7 days for patients without necrosis, and 14 for those with necrosis. Conclusion. We are of the opinion that dartos flaps used in the TIPU method in order to cover neourethra and decrease the incidence of fistula development lead to necrosis in the Ombredanne or Byars' flaps by causing low blood supply to the preputium and thus extend hospital stay.

Urethroplasty by use of turnover flaps (modified mathieu procedure) for distal hypospadias repair in adolescents: comparison with the tubularized incised plate procedure. Korean J Urol 2014; 55:750-5.

Abstract
PURPOSE The purpose of this study was to examine whether urethroplasty with a turnover flap, as an alternative method of distal hypospadias repair in adolescents, improves the outcome of surgery. MATERIALS AND METHODS Between January 2004 and December 2013, a total of 38 adolescents (aged 11-17 years) underwent distal hypospadias repair with either the tubularized incised plate (TIP) procedure (n=25) or the turnover flap procedure (n=13). The turnover flap procedure was performed with a proximal, ventral penile flap that was turned over to cover the urethral plate. Patient demographics, perioperative outcomes, complications, and postoperative uroflowmetry in each surgical group were analyzed retrospectively. RESULTS The patient demographics were similar in the two groups. There were no significant differences in perioperative outcomes between the groups, including mean operative time, duration of hospital stay, and urethral catheterization. The number of patients with at least one complication, including wound dehiscence, urethrocutaneous fistula, meatal stenosis, and urethral stricture, was lower in the turnover flap group (1/13, 7.7%) than in the TIP group (11/25, 44%, p=0.030). The incidence of meatal stenosis was lower in the turnover flap group (0/12, 0%) than in the TIP group (6/25, 24%). In postoperative uroflowmetry, the plateau-shaped curve rate was lower in the turnover flap group (1/12, 8.3%) than in the TIP group (5/19, 26.3%); the peak flow was higher (p=0.030). CONCLUSIONS The turnover flap procedure is clinically useful for repairing adolescent distal hypospadias because it offers lower complication rates and better functional outcomes than TIP.

Abstract
OBJECTIVE We conducted a competitive efficacy trial in order to examine whether grafting the raw area of the urethral plate (UP) with inner preputial skin in children with primary hypospadias (PH) during tubularized incised plate urethroplasty (TIP) improves the results of the operation. MATERIAL AND METHODS Fifty consecutive patients with pathology ranging from glanular to proximal penile PH were randomized into two groups, comparable for age and pathology, to be operated on either with TIP or a grafted TIP (G-TIP) procedure. Three patients failed the re-examination protocol, so the TIP group comprised 23 children aged 9.0 months-9.6 years (mean age 3.4 years) and the G-TIP group comprised 24 children, aged 10.0 months-9.4 years (mean 3.5 years). The patients were followed up for a period of 2-5 years (mean 3.2 years). RESULTS Within the TIP group, we observed the development of fistula with concomitant neourethral stenosis in two cases (8.7%), stenosis without fistula in four (17.4%), and glans dehiscence in one case (4.35%). Within the G-TIP group there was one case of fistula without stenosis (4.16%), no case of neourethral stenosis, and one case of glans dehiscence (4.16%). Two cases of non-slit-like meatus were observed in the TIP group. The results show that the complications of neourethral stenosis are significantly reduced (p < 0.05) in the G-TIP group, as is the total number of complications and unsatisfactory results. The duration of the TIP operation was 72-110 (mean 92) min, and for the G-TIP 100-136 (mean 115) min. No postoperative symptoms were observed that could be attributed to prolonged anesthesia time. CONCLUSION UP grafting with inner preputial skin, when added to the TIP procedure in the treatment of PH, results in a significantly smaller number of unsatisfactory results, and particularly fewer cases of neourethral stenosis. G-TIP can be used as the procedure of choice in PH patients.

Abstract
OBJECTIVE To prospectively evaluate the efficacy and safety of a perimeatal-based penile skin flap for neourethral coverage after repair of distal hypospadias with tubularized incised plate urethroplasty (TIPU). METHODS In 12 New Zealand white rabbits a ventral urethral defect was created and reconstruction was accomplished with continuous suture. An epithelialized defect-based flap was harvested from the penile skin to cover the repaired defect. The animals were euthanized on the 28th postoperative day and their penises were processed for microscopic examination. In 32 children with distal hypospadias a TIPU was performed. A penile skin flap was created immediately below the distal end of the neourethra and used to cover the urethroplasty. RESULTS Histological examinations revealed complete restoration of continuity of the stratified squamous epithelium without evidence of inflammation or fistula formation with full consistency with the underlying papillary reticular and corium. There were no cases of fistula formation. One patient developed meatal stenosis. All patients had a satisfactory cosmetic appearance and excellent functional results. CONCLUSION The formation of a perimeatal-based skin flap is a simple and safe method of providing additional cover for the constructed neourethra after TIPU, minimizing the fistula rate.

Abstract
Hypospadias is a challenging field of urogenital reconstructive surgery with different techniques being currently used. Modern surgery claims that it is possible to create a functionally and cosmetically normal penis. Continuous re-evaluation and assessment of outcome may have a major impact on future clinical practice. Assessment of outcome includes: complication rate, cosmetic appearance of the penis, functional outcome (micturition, sexuality), and psychological factors such as quality of life and psychosexual life. This article briefly reviews current strategies of outcome assessment. Somehow in the future, we will be able to give an accurate estimation of the long-term consequences of being born with hypospadias.

Abstract
OBJECTIVE There is still much debate regarding the effect that age at hypospadias operation has on the rate of complications. The aim of this study was to evaluate whether patient age is a risk factor for surgical complications when using the tubularized incised plate (TIP) urethroplasty technique. METHODS Between 2005 and 2011, 307 pediatric patients with distal or mid-penile hypospadias underwent the TIP procedure. Demographic and surgical data were evaluated. RESULTS The complications recorded across all age groups were: fistula, meatal stenosis, glans dehiscence and urethral stenosis. Fistula was the most frequent complication in 10-14 year olds compared to the younger patient groups, and this difference was statistically significant. CONCLUSION Age and surgical technique should be taken into consideration when planning hypospadias surgery, since the complication rate increases with patient age. The TIP technique is a safe procedure with a low rate of fistula formation in distal and mid-penile hypospadias repair for patients of any age during the prepubertal period.

Abstract
OBJECTIVE Several procedures have been described for repair of distal hypospadias. However, these are not without any complications. Corpus spongiosum advancement is a new technique employed in our patients for distal hypospadias repair with excellent clinical outcome and no post-operative complications. PATIENTS AND METHODS A total of 56 patients aged from 24 to 126 months were operated between January 2009 and August 2011. 32 patients had coronal, 9 had glanular and 15 had distal penile hypospadias. The meatus was located within 1 cm of the corona in all the patients. There was minimal or no chordae. All the patients underwent advancement of corpus spongiosum. RESULT The mean operating time was 36 min and mean operating blood loss was 15 ml. In three patients, the corpus spongiosum was opened inadvertently during dissection. It was repaired with 5-0 vicryl and stitched to the cavernosal bed. An indwelling catheter was kept for 5 days. None of these three patients had any problem after removal of the catheter. Mean hospital stay was 0.5 days (0-6 days). 42 patients were discharged from the hospital on the day of surgery. Eight patients complained of dysuria on the first day. There were no other complications. The functional and cosmetic results have been excellent. The mean follow-up period was 16 months (8-38 months). CONCLUSION Corpus spongiosum advancement is an easy technique, consumes less time and has excellent cosmetic and functional outcome. The procedure is most suitable for children with distal hypospadias without chordae.

Abstract
INTRODUCTION We recently reported a novel modification of the Barcat technique termed glandular resection and central embedding (GRACE). Here, we report results from a large patient population and apply this modification also to Duckett hypospadias repair. PATIENTS AND METHODS We retrospectively evaluated 488 patients who had undergone primary or secondary hypospadias repair by Barcat or Duckett using the GRACE modification. RESULTS For all GRACE repairs, cosmetic appearance was favorable regarding meatal position, shape and overall appearance. Maximum and average flow were above the 5th percentile in at least 95%. In Barcat and Duckett repairs, urethrocutaneous fistulas occurred in 5 and 30.7%, urethral strictures in 3 and 20.8%, and meatal strictures in 5 and 25.3%, respectively. CONCLUSIONS The initially reported favorable cosmetic and functional results were confirmed both for Duckett and Barcat repair using the GRACE modification. Complication rates were favorably low for Barcat and higher, but consistent with published results, for Duckett repair.

[PMID: 22995571 DOI: 10.1016/j.urology.2012.06.058] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2012] [Revised: 06/13/2012] [Accepted: 06/18/2012] [Indexed: 11/28/2022]
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
Aim: Reporting the feasibility of the Denis Browne (buried strip) principle along with tunica vaginalis (TV) pedicled wrapping of the strip in reoperative urethroplasty in hypospadias. Materials and Methods: Over a period of 5 years, 32 patients presented with failure of previous urethroplasty and the range of failure was between 2 and 6 times; mean 2.5 times. Mean age was 12.9 (range 2 to 26 years) years. “Buried strip” urethroplasty (i.e., without tubularization of urethral plate) and wrapping with TV were done along with supra pubic cystostomy (SPC) for diversion of urine. Mean follow-up was 29.8 (range 12 to 56 months) months. Results: One patient had fistula and vertical slit meatus was possible in 26 patients. The flow of urine was satisfactory in 31 patients and one patient developed pouch in penile urethra. Conclusions: The buried strip along with the additional coverage with TV was found to be simple and effective in salvaging the failed urethroplasty.

Abstract
OBJECTIVE To evaluate the results of using a distally folded onlay flap in the repair of distal penile hypospadias, with regard to meatal stenosis, urethrocutaneous fistula and esthetic outcome. PATIENTS AND METHODS This prospective study involved 36 patients with mean age 3.2 years (range 1-4); 18 had a shallow urethral plate, 10 a small glans, and 8 had undergone a previous operation but still had available preputial skin. All underwent the elective technique of distally folded onlay flap, which was carried out under general anesthesia using a 4× magnifying loupe. Starting with penile degloving and then harvesting the transverse island preputial flap provides a flap about 1 cm longer than the urethral plate. Two lateral incisions are made along the urethral plate with no need for dissection deep into the glanular wings. The flap is sutured to the urethral plate, leaving 1 cm distal to the tip of the glans, which is folded back to be sutured to the edges of the glanular wings. RESULTS There were no cases of meatal stenosis or requirement for urethral dilatation. Two patients had a urethrocutaneous fistula; one closed spontaneously while the other needed surgical repair 6 months later. Regarding esthetic appearance, 32 were scored good and 4 satisfactory. CONCLUSION This versatile technique offers satisfactory results regarding meatal stenosis, urethrocutaneous fistula and esthetic outcome.

Abstract
PURPOSE The aim of this retrospective study was to evaluate the functional and cosmetic outcome of tubularized incised plate urethroplasty (TIPU) with preputial reconstruction and preservation of a thin distal urethra when applicable. METHODS The records of 64 boys with hypospadias, who underwent TIPU between 2000 and 2007 were analyzed. 33 (52%) underwent foreskin reconstruction and a thin distal urethra was preserved and incorporated in 19 (30%) patients. The Hypospadias Objective Scoring Evaluation (HOSE), Pediatric Penile Perception Score (PPPS), and uroflowmetry were evaluated in 55 boys (86%) after a mean of 4.8 years. RESULTS All patients had a vertically oriented meatus. The overall rate of fistula occurrence was 9% and of wound dehiscence, 5%. Among 33 preputial reconstructions, two (6%) patients had dehiscence and three (9%) had a fistula. No cases of stricture or stenosis occurred. There were significantly more complications with reconstruction of the foreskin (p = 0.012) and preservation of a thin distal urethra (p = 0.021). Uroflowmetry was normal in 76% of patients. PPPS and HOSE revealed excellent results. CONCLUSION TIPU produces excellent cosmetic and functional results with few complications; complications are more common after foreskin reconstruction and use of a thin distal urethra.

Assessment of urethral plate appearance through digital photography: do pediatric urologists agree in their visual impressions of the urethral plate in children with hypospadias? J Pediatr Urol 2010; 6:294-300. [PMID: 19837634 DOI: 10.1016/j.jpurol.2009.09.003] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2009] [Accepted: 09/03/2009] [Indexed: 11/18/2022]
Abstract
OBJECTIVE There is a paucity of literature on a definition or set criteria evaluating urethral plate (UP) quality. We sought to determine whether pediatric urologists are in agreement in their assessment of UP quality. MATERIALS AND METHODS A cohort of 21 pediatric urologists attending a national annual meeting were surveyed with a questionnaire inquiring about practice patterns and perceived impressions of UP quality. Nineteen sequentially projected, standardized, digital photographs, depicting plates with variable meatal locations, were presented. Intra- and inter-rater agreement among pediatric urologists was estimated by calculating the Kappa statistic (kappa). RESULTS Thirty percent of respondents had more than 15years of practice and one-third repair 10 or more hypospadias per month. Measurement of level of agreement in the impression of UP quality of the 18 projected photographs revealed poor inter-rater agreement (kappa=0.06, P=0.0003), which was not improved by focusing on particular meatal locations or surgeon experience. CONCLUSIONS Despite the inherent shortcomings of digital photography, this study highlights the potential subjectivity and lack of agreement on UP quality. Disagreement seems to be present irrespective of level of the defect or surgeon experience. Setting standards and improving agreement is likely to enhance reporting and interpretation of data in hypospadias studies.

Abstract
OBJECTIVE To compare the outcomes of three different urethroplasty techniques (onlay, buccal mucosa, Koyanagi type I) used in the reconstruction of severe hypospadias. PATIENTS AND METHODS Over 10 years (1997-2007), 300 severe hypospadias cases were treated with a mean follow up of 2 years (1-105 months); 203 were operated by the same surgeon of whom 184 completed follow up. Three main techniques were used according to the quality of the urethral plate: onlay urethroplasty (133), buccal graft urethroplasty (25) and Koyanagi type I (26). The mean age at surgery was 36 months (8-298); 76 required preoperative androgen stimulation (onlay 37, buccal 11, Koyanagi 26); 18 required a corporoplasty to straighten the penis (onlay 13, buccal 3, Koyanagi 2). RESULTS Thirty-eight onlay (28.5%); 14 buccal (56%); 16 Koyanagi (61.5%) urethroplasties had a complication. The fistula rate was 15% for the onlay group; 32% for the buccal mucosa group; 19.2% for the Koyanagi cases. The dehiscence rate was, respectively, 11.3%, 20% and 42.3%. The stricture rate was, respectively, 1.5%, 20% and 34.6%. Urethrocele was found in seven Koyanagi patients. Final functional and cosmetic results were satisfactory in 126/133 (94.7%) onlay, 20/25 (80%) buccal and 14/26 Koyanagi (53.8%) urethroplasties. Primary cases had better results (89%) than redo cases (75.9%). Patients submitted to preoperative androgen therapy developed more complications (onlay: 40.5% vs 23.9%; buccal: 70% vs 43.7%). CONCLUSION Two striking results are the low number of severe hypospadias cases requiring an additional corporoplasty, and the increased complication rate found in androgen-stimulated patients. The excellent results of the onlay procedure could be related to the use of dorsal preputial tissue, which in hypospadias is characterized by a well-balanced protein platform compared to the ventral tissues.
