Rab25 is involved in hypospadias via the ß1 integrin/EGFR pathway.

BACKGROUND: Hypospadias is a common congenital abnormality of the penile. Abnormal regulation of critical genes involved in urethral development leads to hypospadias. We used the Rab25-/- mice and foreskin fibroblasts transfected with lentivirus in vitro and in vivo to investigate the role of Rab25 in hypospadias. METHODS: The expression levels of various molecules in tissue samples and foreskin fibroblasts were confirmed using molecular biology methods (western blotting, PCR, immunohistochemistry, etc.). A scanning electron microscope (SEM) was used to visualize the external morphology of genital tubercles (GTs) of gestation day (GD) 18.5 male wild-type (WT) and Rab25-/- mice. RESULTS: An expanded distal cleft and V-shaped urethral opening were observed in GD 18.5 Rab25-/- mice. We demonstrated that Rab25 mediated hypospadias through the ß1 integrin/EGFR pathway. In addition, silencing Rab25 inhibited cell proliferation and migration and promoted apoptosis in the foreskin fibroblasts; Ki-67- and TUNEL-positive cells were mainly concentrated near the urethral seam. CONCLUSION: These findings suggest that Rab25 plays an essential role in hypospadias by activation of ß1 integrin/EGFR pathway, and Rab25 is a critical mediator of urethral seam formation in GD18.5 male fetal mice.

Meconium Concentrations of Pesticides and Risk of Hypospadias: A Case-Control Study in Brittany, France.

BACKGROUND: Hypospadias is a male genital tract defect for which an increase in prevalence has been documented over the last few decades. A role for environmental risk factors is suspected, including prenatal exposure to pesticides. OBJECTIVES: To study the risk of hypospadias in association with multiple pesticide measurements in meconium samples. METHODS: The Brittany Registry of Congenital Anomalies (France) conducted a case-control study between 2012 and 2018. Cases were hypospadias, ascertained by a pediatrician and a pediatric surgeon, excluding genetic conditions, following European Surveillance of Congenital Anomalies guidelines (N = 69). Controls (N = 135) were two male infants without congenital anomaly born after each case in the same maternity unit. Mothers in the maternity units completed a self-administered questionnaire, we collected medical data from hospital records, and medical staff collected meconium samples. We performed chemical analysis of 38 pesticides (parent compound and/or metabolite) by UHPLC/MS/MS following strict quality assurance/quality control criteria and blind to case-control status. We carried out logistic regression accounting for frequency-matching variables and major risk factors. RESULTS: Among the 38 pesticides measured, 16 (42%) were never detected in the meconium samples, 18 (47%) were in <5% of samples, and 4 (11%) in ≥5% of the samples. We observed an association between the detection of fenitrothion in meconium and the risk of hypospadias (OR = 2.6 [1.0-6.3] with n cases = 13, n controls = 21), but not the other pesticides. CONCLUSIONS: Our small study provides a robust assessment of fetal exposure. Fenitrothion's established antiandrogenic activities provide biologic plausibility for our observations. Further studies are needed to confirm this hypothesis.

A Japanese patient with Teebi hypertelorism syndrome and a novel CDH11 EC1 domain variant.

The gene CDH11 encodes cadherin-11, a Type II cadherin superfamily member that contains five extracellular cadherin (EC) domains. Cadherin-11 undergoes trans-dimerization via the EC1 domain to generate cadherin complexes. Compound heterozygous and homozygous loss-of-function CDH11 variants are observed in Elsahy-Waters syndrome (EWS), which shows characteristic craniofacial features, vertebral abnormalities, cutaneous syndactyly in 2-3 digits, genitourinary anomalies, and intellectual disability. Heterozygous CDH11 variants can cause Teebi hypertelorism syndrome (THS), which features widely spaced eyes and hypospadias. We report a THS patient with a novel CDH11 variant involving the EC1 domain. The patient was a 10-month-old male with normal developmental milestones, but had widely spaced eyes, strabismus, hypospadias, shawl scrotum, broad thumbs (right bifid thumb in x-ray), polysyndactyly of the left fourth finger, and cutaneous syndactyly of left third/fourth fingers. Exome sequencing identified a de novo heterozygous CDH11 variant (NM_001797.4:c.229C > T [p.Leu77Phe] NC_000016.9:g.64998856G > A). Clinical features were consistent with previously reported THS patients, but polysyndactyly, broad thumb, and cutaneous syndactyly overlapped phenotypic features of EWS. THS and EWS may represent a spectrum of CDH11-related disorders. Residue Leu77 in this novel CDH11 variant lines a large hydrophobic pocket where side chains of the partner cadherin-11 insert to trans-dimerize, suggesting that the cadherin-11 structure might be altered in this variant.

Maternal periconceptional folic acid supplementation and risk for fetal congenital genitourinary system defects.

BACKGROUND: Taking folic acid supplementation could reduce the risk of neural tube defects for offspring in the maternal periconceptional period, but the relationship between folic acid use and other birth defects remains unclear, such as genitourinary system birth defects. METHODS: The data from a Prenatal Health Care System and Birth Defects Surveillance System in Tongzhou, Beijing, China, were collected from 2013 to 2018. We adjusted for differences in characteristics between comparison groups using propensity score inverse probability weighting and assessed associations with Poisson regression modeling. RESULTS: A total of 65,418 live births and stillbirths were included, and there were 194 cases with congenital genitourinary defects among them. The prevalence of genitourinary system birth defects was 29.2 (34.9) per 10,000 for FA/MMFA users (nonusers). Compared to nonusers, FA/MMFA users had a lower risk for genitourinary system birth defects (adjusted risk ratio [aRR] 0.81, 95% confidence interval [CI] 0.67, 0.98), and for hypospadias (aRR 0.55, 95% CI 0.40, 0.76). CONCLUSIONS: FA or MMFA supplementation during the maternal periconceptional period could reduce the risk for genitourinary system birth defects in offspring. More mechanisms should be explored for the protective effect. IMPACT: Folic acid (FA) or multiple micronutrients containing folic acid (MMFA) supplementation during the maternal periconceptional period could reduce the risk for genitourinary system birth defects in offspring. Maternal FA/MMFA supplementation during the periconceptional period may reduce the risk for hypospadias.

Maternal physical activity, sitting, and risk of non-cardiac birth defects.

BACKGROUND: The relationship between maternal physical activity (PA)/sitting and birth defects is largely unexplored. We examined whether pre-pregnancy PA/sitting were associated with having a pregnancy affected by a birth defect. METHODS: We used data from two United States population-based case-control studies: 2008-2011 deliveries from the National Birth Defects Prevention Study (NBDPS; 9 states) and 2014-2018 deliveries from the Birth Defects Study To Evaluate Pregnancy exposureS (BD-STEPS; 7 states). Cases with one of 12 non-cardiac birth defects (n = 3798) were identified through population-based registries. Controls (n = 2682) were live-born infants without major birth defects randomly sampled using vital/hospital records. Mothers self-reported pre-pregnancy PA/sitting. Unconditional logistic regression models estimated associations between PA/sitting categories and the 12 birth defects. RESULTS: Mothers engaging in pre-pregnancy PA was associated with a reduced odds of five (spina bifida, cleft palate, anorectal atresia, hypospadias, transverse limb deficiency) and a higher odds of two (anencephaly, gastroschisis) birth defects. Mothers spending less time sitting in pre-pregnancy was associated with a reduced odds of two (anorectal atresia, hypospadias) and a higher odds of one (cleft lip with or without cleft palate) birth defect. CONCLUSIONS: Reasonable next steps include replication of these findings, improved exposure assessment, and elucidation of biologic mechanisms. IMPACT: Using data from two population-based case-control studies, we found that mothers engaging in different types of physical activity in the 3 months before pregnancy had an infant with a reduced odds of five and a higher odds of two birth defects. Mothers spending less time sitting in the 3 months before pregnancy had an infant with a reduced odds of two and a higher odds of one birth defect. Clarification and confirmation from additional studies are needed using more precise exposure measures, distinguishing occupational from leisure-time physical activity, and elucidation of mechanisms supporting these associations.

Primary hypospadias repair outcomes: results from a retrospective cohort of 292 children.

PURPOSE: Hypospadias surgery is challenging. Numerous techniques have been described with variable complication rates. The main objectives of our study were to evaluate the urethroplasty complication rate of primary hypospadias repair and to identify risk factors for complications. METHODS: We retrospectively evaluated the outcomes of all patients who underwent primary hypospadias repair in our department between January 2012 and December 2020. Demographic, anatomical, operative, and postoperative data were reported. Univariate and multivariate logistic regression analyses were performed to identify variables associated with complications. Statistical significance was set at p < 0.05. RESULTS: Of 292 patients, 203 (69.5%) had distal hypospadias, 63 (21.6%) had mid-penile hypospadias, and 26 (8.9%) had proximal hypospadias. The mean age at the time of surgery was 22.8 months. Seventy-eight patients (26.7%) had urethroplasty complications. The rate of complications was higher for proximal hypospadias (57.7%), onlay island flap (44.4%), and Koyanagi (75%) procedures. The mean follow-up duration was 29 months. Two predictors of complications were identified by multivariate analysis: catheterization duration and urethroplasty technique. The reoperation rate was 30.5%. CONCLUSION: Urethroplasty complications frequently occur after primary hypospadias repair. The complication rate was higher in proximal hypospadias. Catheterization duration and surgical technique were significant predictors of complications. A longer and more standardized follow-up is needed for a better assessment of hypospadias repair outcomes.

What should be next in lifelong posterior hypospadias: Conclusions from the 2023 ERN eUROGEN and EJP-RD networking meeting.

BACKGROUND: A congenital disease is for life. Posterior hypospadias, the severe form of hypospadias with a penoscrotal, scrotal, or perineal meatus, is a challenging condition with a major impact on lifelong quality of life. AIM: Our network meeting is aimed to identify what is currently missing in the lifelong treatment of posterior hypospadias, to improve care, quality of life, and awareness for these patients. METHODS: The network meeting "Lifelong Posterior Hypospadias" in Utrecht, The Netherlands was granted by the European Joint Programme on Rare Diseases-Networking Support Scheme. There was a combination of interactive sessions (hackathons) and lectures. This paper can be regarded as the last phase of the hackathon. RESULTS: Surgery for hypospadias remains challenging and complications may occur until adulthood. Posterior hypospadias affects sexual function, fertility, and hormonal status. Transitional care from childhood into adulthood is currently insufficiently established. Patients should be more involved in defining desired treatment approach and outcome measures. For optimal outcome evaluation standardization of data collection and registration at European level is necessary. Tissue engineering may provide a solution to the shortage of healthy tissue in posterior hypospadias. For optimal results, cooperation between basic researchers from different centers, as well as involving clinicians and patients is necessary. CONCLUSIONS: To improve outcomes for patients with posterior hypospadias, patient voices should be included and lifelong care by dedicated healthcare professionals guaranteed. Other requirements are joining forces at European level in uniform registration of outcome data and cooperation in basic research.

MicroR-1199-5p targeting SRD5A2 promotes the biological behavior and EMT of hypospadias cells.

Hypospadias, an oft-occurring penis anomaly, ranks among neonatal's foremost birth defects. The SRD5A2 can affect male reproductive system development and is abnormally expressed in its epithelial cells. This study exploration aimed at understanding the role of SRD5A2 in the development of hypospadias from a molecular perspective. SRD5A2 levels in hypospadias primary cells were analyzed by Western blot, while targeted interaction with miR-1199-5p was ascertained by dual-luciferase gene reporter assay. In vitro biological experiments were used to confirm the biological function of SRD5A2 in hypospadias. SRD5A2 expression was significantly upregulated, and miR-1199-5p expression was significantly downregulated in hypospadias primary cells. Intervention of SRD5A2 expression can affect cell proliferation, migration, invasion, EMT, and the expression of cell cycle-related proteins. Additionally, we found that SRD5A2 is regulated by upstream miR-1199-5p and can enhance the effect of SRD5A2 on hypospadias cells. Conclusions Silencing SRD5A2 promotes cell proliferation, invasion, and migration blocks the cell cycle at the G1 phase, and simultaneously promotes EMT, cell cycle, and cell proliferation-related protein expression. The biological function of SRD5A2 in hypospadias cells is regulated by miR-1199-5p. SRD5A2 may be an effective therapeutic target for hypospadias.

Adult Hypospadias Outcomes for the Pediatric Urologist.

PURPOSE OF REVIEW: This review article will examine the current literature on hypospadias-related complications in adult patients. RECENT FINDINGS: In this article, we will review the most recent studies evaluating hypospadias-related stricture disease, erectile function, fertility, and psychosexual outcomes in adult men with history of hypospadias repair in childhood. Managing hypospadias-related complications in adult patients is challenging to reconstructive urologists due to the compounded complexity of innate tissue deficiency and history of prior surgical repairs. In this review, we explore overall functional outcomes of adults with history of hypospadias repair as well as repair strategies of hypospadias-related urethral stricture disease. We will review erectile function, fertility and psychosexual outcomes as well as potential complications, which often do not surface until late adolescence and adulthood. Although it is challenging to characterize and quantify hypospadias-related complications, further longitudinal study is needed to better care for this complex patient population.

Comparison of outcome of TIP urethroplasty with or without Buck's Fascia repair.

OBJECTIVE: TIP is the most common preformed type of Urethroplasty. The intermediate barrier is used as a waterproofing layer to prevent fistula formation. Many tissues have been utilized as a barrier layer, with varying success rates. The search for a better intermediate layer will continue. In this study, we aim to evaluate the role of Buck's Fascia as a covering for the neo-urethra to prevent fistula formation in patients who underwent Snodgrass Urethroplasty. METHODS: This prospective study was conducted between 2018 and 2022. Patients were randomly assigned to either Group 'A' or Group 'B'. Group A included patients who underwent the Snodgrass procedure with a Buck's Fascia cover, while Group B included patients whose neo-urethra was covered with the dartos flap. These patients were closely monitored for the development of short- and long-term complications in both groups, and the results were recorded. RESULTS: The study involved 164 patients, who underwent midpenile and distal hypospadias repair using the Snodgrass technique. In Group 'A' (84 patients), the neo-urethra was covered with Buck's Fascia, while in Group 'B' (80 patients), the neo-urethra was covered with the dartos flap. The mean age of the children was (23.06 ± 16.12) months in group 'A' & (26.06 ± 14.07) months in group 'B'. mean operating time was (40 ± 11.43) minutes, in Group 'A', and (70 ± 17.43) minutes, in Group 'B'. Meatal stenosis occurred in 3.57% of children in Group 'A' and 10% of patients in Group 'B'. Urethral fistulas were encountered in 2.35% of cases in Group 'A'and 10% in Group 'B'. The difference between the groups was statistically significant.

Evaluation of postoperative complications of hypospadias using high-frequency ultrasound imaging.

PURPOSE: Various complications following hypospadias surgery present distinct manifestations when examined with ultrasound. Utilizing high-frequency ultrasound, clinicians can promptly identify these complications and initiate appropriate treatment. The aim of this study is to catalogue the ultrasonographic presentations of various postoperative complications following hypospadias surgery, thereby providing a reference for ultrasonographic diagnosis. METHODS: Ultrasonic images of post-hypospadias surgery from October 1, 2015, to June 30, 2023, recorded at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, serve as the basis for this investigation. Drawing on patient clinical diagnoses, this study compiles and selects representative ultrasound images of diverse complications. RESULTS: The study encompassed a total of 121 subjects; 26 demonstrated urethral stricture on ultrasonic images, two presented local urethral dilation, six showed intraurethral hair-like structures, 17 revealed intraurethral septum, two exhibited intraurethral fold, one had urethral calculus, one displayed urethral calcification, 12 indicated intraurethral urine accumulation, and two showed urethral diverticulum. CONCLUSION: Ultrasound examination is helpful for postoperative diagnosis following hypospadias, detecting complications such as urethral stricture, urethral hair growth, and urethral diverticulum, which can help doctors choose appropriate clinical treatment strategies.

The potentiating effect of intravenous dexamethasone upon preemptive pudendal block analgesia for hypospadias surgery in children managed with Snodgrass technique: a randomized controlled study : Dexamethasone for pain management in children.

INTRODUCTION: Evidence regarding the potentiating effects of intravenous dexamethasone on peripheral regional anesthesia in children is sparse. The objective of the current study was to investigate the potentiating effect of intravenous dexamethasone upon pudendal block during surgical correction of hypospadias using Snodgrass technique. METHODS: The study consisted of a monocentric, randomized controlled, double-blinded study. Patients were randomized to receive either intravenous dexamethasone 0.15 mg.kg- 1 (D group) or a control solution (C group). Both groups received standardized anesthesia including a preemptive pudendal block performed after the induction of anesthesia. The primary outcome was the proportion of patients needing rescue analgesia. Secondary outcomes were other pain outcomes over the first 24 postoperative hours. RESULTS: Overall, 70 patients were included in the study. Age were 24 [24; 36] and 26 [24; 38] months in the D and C groups, respectively (p = 0.4). Durations of surgery were similar in both groups (60 [30; 60], p = 1). The proportion of patients requiring rescue analgesia was decreased in the D group (23% versus 49%, in D and C groups respectively, p = 0.02). The first administration of rescue analgesia was significantly delayed in the D group. Postoperative pain was improved in the D group between 6 and 24 h after surgery. Opioid requirements and the incidence of vomiting did not significantly differ between groups. CONCLUSION: Associating intravenous dexamethasone (0.15 mg.kg- 1) to pudendal block during hypospadias surgery improves pain control over the first postoperative day. Further studies are needed in order to confirm these results. GOV IDENTIFIER: NCT03902249. A. WHAT IS ALREADY KNOWN: dexamethasone has been found to potentiate analgesia obtained with regional anesthesia in children. B. WHAT THIS ARTICLE ADDS: intravenous dexamethasone was found to improve analgesia with a preemptive pudendal block during hypospadias surgery. C. IMPLICATIONS FOR TRANSLATION: results of this study indicate that intravenous dexamethasone could be used as an adjunct to pudendal block.

The long-term consequences of the hypospadias salvage repair issue.

PURPOSE: To present the long-term results of redo-hypospadias at our tertiary referral center following a failed prior repair. METHODS: One hundred sixty-four individuals with a history of unsuccessful repairs qualified for our retrospective cohort study. Our inclusion criteria were as follows: pre-operative data that was accessible, redo-hypospadias that was successfully repaired, and at least three years of follow-up at the last hospital visit. RESULTS: The mean patient age was 91.3 ± 21.1 months. The mean follow-up after successful repair was 41.3 ± 3.1 months. Ninety-two (group A) had one prior repair, and 72 (group B) had 2 or 3 repairs. Group A underwent six primary techniques: 32 underwent Onlay Island Flap (OIF), 10 underwent Mathieu, 12 underwent Tubularized Incised Plate Urethroplasty (TIPU), 8 underwent Urethral Mobilization (UM), and 34 underwent Buccal Mucosal Graft (BMG) { dorsal inlay Graft Urethroplasty (DIGU) in 4 and staged BMG in 30 patients}. In group B, four procedures were used: TIPU in 4, UM in 6, and BMG in 62 (staged BMG in 50 cases and DIGU in 12). CONCLUSIONS: The selected type of repair will depend on many factors, like residual healthy local skin and expertise. Safe techniques for repair of redo hypospadias after its 1st failure include TIPU, Mathieu, UM, OIF, and DIGU for distal varieties. After 2nd or 3rd repair DIGU, UM, and TIPU can be performed in distal types, while staged BMG can be applied for proximal ones.

Intravenous dexamethasone does not prolong the duration of pudendal nerve block in infants and children undergoing hypospadias surgery: A randomized clinical trial.

BACKGROUND: The administration of intravenous dexamethasone increases the duration of neuraxial block and improves the quality of analgesia. However, little is known about these effects of dexamethasone on peripheral nerve blocks in children. AIMS: In this study, we aimed to investigate the benefit of intravenous dexamethasone for enhancing the effect of pudendal block on postoperative analgesia in children who underwent hypospadias surgery. METHODS: In total, 46 children aged 6-36 months who underwent hypospadias surgery were randomly allocated to either a control group (normal saline, group C) or dexamethasone group (0.5 mg/kg, group D). Pudendal block was performed before the surgery using 0.3 mL/kg of 0.225% ropivacaine on both sides. Parents were instructed to press the patient-controlled analgesia bolus button when their children's pain score was >4 points. The primary outcome measure was the time at which the first patient-controlled analgesia by proxy bolus dose was administered. The secondary outcome measures were pain score, number of patient-controlled analgesia administration by proxy bolus attempts, number of rescue analgesics required, total amount of fentanyl administered, and overall parental satisfaction. RESULTS: The time of first patient-controlled analgesia bolus administration by proxy was not different between the control and dexamethasone groups (5.6 [5.2, 8.8] h versus 6.5 [5.4, 8.1] h, hazard ratio 0.8, 95% confidence intervals 0.43 to 1.47, p = .46). There were no statistically significant differences among the secondary outcomes. CONCLUSIONS: Administration of intravenous dexamethasone did not enhance the duration of pudendal nerve block in infants and children aged 6-36 months who underwent hypospadias surgery.

Maternal Diabetes and Risk of Hypospadias: A Systemic Review and Meta-Analysis.

INTRODUCTION: This study aimed to investigate the association between maternal diabetes and the risk of hypospadias in male infants, as the relationship between them remains uncertain. METHODS: To comprehensively evaluate the association between pregestational diabetes mellitus and gestational diabetes mellitus with hypospadias, we conducted a systematic review and meta-analysis. A thorough literature search was conducted, encompassing relevant publications published prior to January 2023. Crude odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were calculated using a random-effects model. RESULTS: Our meta-analysis comprised a total of 13 studies, 11 of which investigated the relationship between pregestational diabetes mellitus and hypospadias, while 9 studies explored the association between gestational diabetes mellitus and hypospadias. Notably, these investigations yielded compelling evidence of significant positive associations between pregestational diabetes mellitus and hypospadias (OR = 1.51, 95% CI = 1.13-2.03), as well as between gestational diabetes mellitus and hypospadias (OR = 1.18, 95% CI = 1.04-1.35). CONCLUSION: Our findings suggest that both pregestational diabetes mellitus and gestational diabetes mellitus are associated with an increased risk of hypospadias in offspring. Further investigations are needed to explore the optimal range of blood glucose during pregnancy that minimizes the risk of congenital malformation in the fetus, as well as to develop more effective measures for glycemic control in pregnant women.

Maternal exposure to dibutyl phthalate (DBP) impairs angiogenesis and AR signalling pathway through suppression of TGFB1I1 in hypospadias offspring.

Early exposure to dibutyl phthalate (DBP) can cause hypospadias in newborn foetuses. However, the underlying molecular mechanism is not well defined. Aberrant angiogenesis is associated with various dysplasias including urogenital deficits. In vivo and in vitro angiogenesis assays showed reduced angiogenesis in the hypospadias group and DBP exposed group. RNA-sequencing analysis of DBP-treated HUVECs revealed decreased expression of transforming growth factor beta 1-induced transcript 1 (TGFB1I1) and a significantly enriched angiogenesis-associated pathway. Further experiments revealed that decreased TGFB1I1 expression was associated with disrupted tube formation and migration, which resulted in decreased angiogenesis. Functional assays revealed that the overexpression of TGFB1I1 promoted tube formation and migration of HUVECs in the DBP-treated group. Moreover, we showed that the transcription factor AR was regulated by TGFB1I1 through inhibiting its translocation from the cytoplasm to the nucleus. Together, our results identified TGFB1I1 as a component of aberrant angiogenesis in hypospadias rats and its interaction with AR might be a potential target for hypospadias development.

Risk factors and timing of complication presentation following primary hypospadias repair in adolescents.

OBJECTIVES: To evaluate the risk factors for postoperative complications in adolescents who undergo primary hypospadias repair and determine the time required for complication detection. METHODS: Our study included patients classified as Tanner stages three to five who underwent primary hypospadias repairs at our hospital from January 2015 to August 2022. The patients' baseline information, clinical characteristics, postoperative complications, and time to complication detection were collected. Cox regression analysis, ROC curves, Kaplan-Meier survival analyses, and the Mann-Whitney U test were used. RESULTS: The study comprised 143 patients, with a median age of 12.58 years. Postoperative complications were experienced by 66 patients. The length of the urethral defect was identified as an independent risk factor for postoperative complications. The ROC curve analysis identified 3 cm as the optimal cutoff value for the length of the urethral defect. The median time to complication detection was 30.5 days (IQR 23 to 209.25). 89.4% of the complications were identified within the first year. Patients with a urethral defect of <3 cm experienced a significantly longer time for the detection of urethral fistula compared to those with a urethral defect of ≥3 cm (p = 0.047). CONCLUSIONS: Our data indicate that adolescents with a urethral defect ≥3 cm have a higher risk of postoperative complications. Although most complications were identified within the first year, conducting long-term follow-ups for adolescents is recommended to identify potential subsequent complications that may arise from persistent urethral alterations.

The "V-I penoscrotal reconfiguration": A simple technique for the surgical treatment of congenital webbed penis.

OBJECTIVES: To describe a new penoscrotal reconfiguration technique, named "V-I penoscrotal reconfiguration" for the surgical reconstruction of a congenital webbed penis (CWP). METHODS: Twenty-one patients who underwent the "V-I penoscrotal reconfiguration technique" were included in this retrospective study. The CWP severity was assessed according to El-Koutby's classification. Demographic and clinical data, surgical data, and postoperative outcomes were scheduled and analyzed. Specifically, the postoperative follow-up included both physical and psychological assessments at 2 weeks, 1, 6, and 12 months after surgery. Parents' satisfaction degree was quantified by the Likert scale. RESULTS: CWP was grade 3 in 11 (52%) patients, 2 in five (24%), and 1 (24%) in five. Five (24%) CWP were isolated malformations, 11 (52%) were associated with phimosis, three (14%) with hypospadias, and two (10%) with hypospadias and phimosis. There were no postoperative complications and no cases of redo surgery. The cosmetic outcomes were excellent in all cases: the parents' satisfaction score was 4 in 17 (81%) cases and 3 (9%) in the other four cases. CONCLUSIONS: CWP may cause psychological distress and functional problems, especially during sexual intercourse. Its correction in childhood is advocated to prevent psychological and sexual issues. The "V-I reconfiguration technique" is simple, and easy with excellent cosmetic and functional outcomes.

Widening of narrow urethral plates with lateral skin in TIP hypospadias repair: single center series.

BACKGROUND: To compare the outcomes of hypospadias repair using tubularized incised plate (TIP) urethroplasty and modified TIP with lateral skin to widen the urethral plate (WTIP). MATERIALS AND METHODS: Data were obtained from pre-pubertal boys who underwent primary hypospadias repair between May 2018 and July 2023. The cases were divided into two groups; one group underwent TIP with urethral plate ≥ 6 mm width and the other group with urethral plate width < 6 mm underwent WTIP. WTIP urethroplasty was performed by widening incisions on the outer margins of the urethral plate to incorporate penile and glandular skin lateral to the urethral plate to facilitate tubularization. Complication rates and urinary functions were compared. RESULTS: A total of 157 patients were enrolled in this study. Eighty-eight cases with narrow urethral plate were subjected to WTIP urethroplasty, and the rest were subjected to TIP urethroplasty. The preoperative glans width in WTIP group was less than that in TIP group (P < 0.001), and 44.3% had midshaft meatus in WTIP group compared to 17.4% in TIP group (P < 0.001). However, the incidences of postoperative complications (17.6% vs. 21.6%, P = 0.550) were not statistically different between the TIP and WTIP groups. In addition, both groups did not differ significantly in postoperative uroflowmetry assessment. CONCLUSIONS: The described technique helps to create an adequately caliber aesthetic neomeatus and facilitates tubularization, especially in hypospadias with a narrow urethral plate. Our data suggest that augmentation of a narrow urethral plate with WTIP has a similar surgical outcome to that of the TIP procedure in patients with a wide urethral plate.

Expert classification of hypospadias: an external validation and evaluation of agreement for Glans-Urethral Meatus-Shaft (GMS) and Hypospadias Objective Penile Evaluation (HOPE) scores.

PURPOSE: This study evaluates the inter-rater agreements of both the Glans-Urethral Meatus-Shaft (GMS) hypospadias score and Hypospadias Objective Penile Evaluation (HOPE) score, aiming to standardize disease classification for consistent agreement in clinically relevant characteristics of hypospadias. METHODS: Photos of hypospadias in children were collected from two separate institutions. Three raters scored the photos using GMS and HOPE, excluding penile torsion and curvature assessment in HOPE due to photo limitations. RESULTS: A total of 528 photos were included. With GMS, Fleiss' multi-rater kappa showed an agreement of 0.745 for glans-urethral plate, 0.869 for meatus, and 0.745 for shaft. For HOPE scores, the agreements were 0.888 for position of meatus, 0.669 for shape of meatus, 0.730 for shape of glans, and 0.708 for the shape of the skin. The lower agreement in the shape of the meatus evaluation may be attributed to the lack of a quantitative classification method in HOPE. Experts rely on their subjective judgment based on the provided example photos and their index patient. CONCLUSIONS: While there is high agreement among experts when evaluating hypospadias using the GMS and HOPE scoring criteria, only the position of the meatus achieved nearly perfect agreement highlighting that the current scoring systems entail a subjective element in disease classification.
