Objective:To investigate the clinical efficacy of labial mucosa graft coupled preputial island flap urethroplasty for recurrent penile curvature after hypospadias repair.Methods:The data of 35 patients with recurrent penile curvature after hypospadias repair who underwent labial mucosa graft coupled preputial island flap urethroplasty in four hospitals from January 2021 to March 2023 were retrospectively reviewed. The median age of the patients was 15(13, 18)years old, five of them had penile dehiscence, and four had urethrocutaneous fistula. All patients received labial mucosa graft coupled preputial island flap urethroplasty, the penile flexion was confirmed by artificial erection test, and the urethra is obliquely cut at the most obvious curvature of the penis. By removing the ventral fibrotic scar tissue, the length of the urethral defect was measured. The urethral plate was reconstructed with the same length of labial mucosa graft and an adjacent preputial island flap was transplanted to cover the reconstructed urethra plate to form a new urethral lumen. The inner urethral stent tube was extracted three days after the operation, and the outer urethral stent tube was removed three weeks after the surgery. Diagnostic urethral exploration was performed 5 weeks post-operation, uroflowmetry examination was performed seven weeks after the procedure, and the perioperative and postoperative follow-up data were analyzed.Results:All patients underwent a successful surgery, with the average duration of the procedure being (114.7±20.1)minutes. After mean follow-up of (15.5±5.9)months, no penile curvature occurred, and 32 patients were successfully repaired. Uroflowmetry examination was achieved in 21 patients at the seventh week after surgery showed their mean maximum flow rate was (18.4±3.7)ml/s. Three cases (8.6%, 3/35) developed urethrocutaneous fistula, who were repaired successfully 6 months after surgery.Conclusions:Utilizing the combination of labial mucosa grafts and preputial island flaps for urethroplasty has been proven to be a reliable and safe option for individuals with recurrent penile curvature following hypospadias repair, with a high success rate and few complications.
摘要
The use of buccal mucosa grafts in urethral reconstruction for complex anterior urethral strictures has gained popularity over the years with very good outcomes reported in literature. Simultaneously newly launched integra dermal graft is been used as Onlay flap for postoperative hypospadias urethro-cutaneous fistula closure as reported in world wide literature. The aim of this case report is to compare pros and cons of use of Integra Dermal Graft as an alternative to staged Buccal mucosal graft urethroplasty in case of 13 years old boy with multiple postoperative hypospadias fistulae.

Objectives: The purpose of this study was to see the effect of parenteral testosterone injection on penile length, glans diameter, and diameter at the base of the penis in hypospadias patients before surgery. Material and Methods: The study was conducted from September 2019 to March 2021. This study comprised a total of 20 hypospadias patients. At a dose of 2 mg/kg body weight, an injection testosterone propionate was administered deep intramuscularly in three doses with a 3-week gap before reconstructive surgery. Before surgery, the penile length, glans diameter, and penile diameter at the base of the penis were all measured. Results: The mean increase in penile length, glans diameter, and diameter at the base of penis following parenteral testosterone therapy was 1.07 ± 0.23 cm (P < 0.001), 1.01 ± 0.46 cm (P < 0.001), and 0.92 ± 0.12 cm (P < 0.001), respectively. All three measurements were statistically significant. Conclusion: Intramuscular testosterone increased penis size, glans diameter, and penile diameter without causing any notable side effects. Development of fine pubic hair, acne, and aggressiveness is minor adverse effects.

Objective:To investigate the association between preterm birth, low birth weight and the risk of hypospadias.Methods:According to the search strategy of Cochrance Collaborative Network, the China National Knowledge Internet (CNKI), VIP, Wanfang, Pubmed, Cochrance and Embase were searched from the establishment of the database to April 2022. The literature on the relationship between preterm birth, low birth weight and the risk of hypospadias was included. Meta analysis was conducted on the relationship between preterm birth, low birth weight and the risk of hypospadias.Results:A total of 13 articles were included, including cases from Asia, Europe, Australia and America. Newcastle-ottawa Scale was used for evaluation, and the scores were all above 6. There were 10 articles on the relationship between preterm birth and the risk of hypospadias, all of which were case-control studies. Heterogeneity test I2=46%, P=0.05. There were 3 521 cases in the case group and 95 816 cases in the control group. Compared with the control group, preterm birth was a risk factor for hypospadias ( OR: 2.13, 95% CI: 1.89-2.41), and the difference was statistically significant ( Z=12.21, P<0.01). There were 11 articles on the association between low birth weight and the risk of hypospadias, all of which were case-control studies. Heterogeneity test I2=47%, P=0.04. There were 2 460 cases in the case group and 94 260 cases in the control group. Compared with the control group, low birth weight was a risk factor for hypospadias ( OR: 3.29, 95% CI: 2.57-4.22), and the difference was statistically significant ( Z=9.40, P<0.01). Conclusions:Based on meta-analysis of published literature, preterm birth and low birth weight increase the risk of hypospadias.

Objective To explore the efficacy and prognostic independent factors of modified island flap(OIF)and urethroplasty(tip)in the treatment of hypospadias in children.Methods The 164 children with hypospadias analyzed retrospectively were treated from February,2013 to February,2021.They were divided into two groups according to the operation method.82 patients in tip group were treated with tip and 82 patients in OIF group were treated with OIF.The treatment effects of the two groups were compared.Then they were divided into two groups according to the cure condition,namely,the good prognosis group(cured by operation,151 case)and the poor prognosis group(not cured by operation,13 case).Independent factors affecting the prognosis of children were analyzed by binary logistic regression.Results The cure rate of OIF group was 96.34％,which was higher than that of the tip group(87.8％),and the incidence of postoperative complications in OIF group was 7.32％,which was lower than that of the tip group(23.17％,P＜0.05).The operation time in tip group(95.95±12.35)min,which was shorter than that of the OIF group(P＜0.05).At the same time,the binary logistic regression analysis showed that the degree of hypospadias and the classification of barcat were the prognostic factors of children with hypospadias.The degree of penis bending,the width of penis head and the method of operation were suspicious factors.Conclusion OIF and tip have good effects in the treatment of hypospadias in children.OIF has a higher success rate,tip has a shorter operation time and fewer postoperative complications.However,the independent factors affecting the prognosis of children are preoperative hypospadias classification and barcat classification.This operation method is not an independent factor affecting the prognosis.
摘要
Urethrocutaneous fistula may complicate hypospadias repair. We noticed that double-layered preputial dartos flaps added to tubularized incised plate urethroplasty can reduce the risk of urethrocutaneous fistula. The aim of this study was to compare the outcomes of tubularized incised plate urethroplasty with double-layered preputial dartos flaps to with single-layered local fascial flaps in preventing urethrocutaneous fistula. A retrospective cohort study was conducted between January 2017 and December 2020 at Jordan University Hospital (Amman, Jordan). Boys who were aged between 6 months and 5 years, diagnosed with distal hypospadias, and not circumcised were included. The primary outcome was the occurrence of urethrocutaneous fistula in patients who underwent tubularized incised plate urethroplasty with a double-layered fascial flap. The results showed a total of 163 boys with distal hypospadias; among them, 116 patients underwent tubularized incised plate urethroplasty with a single-layered fascial flap, and 47 underwent tubularized incised plate urethroplasty with a double-layered fascial flap. The development of urethrocutaneous fistula was higher in the group receiving tubularized incised plate urethroplasty with a single-layered fascial flap than in the group receiving tubularized incised plate urethroplasty with a double-layered fascial flap after 1 month, 6 months, and 12 months (6.9% vs 0, 10.3% vs 0, and 5.2% vs 0, respectively), and the difference after 6 months was statistically significant (P = 0.02).

Objective:To evaluate the mid-term complication rates of the Hui-Jing one-stage procedure (lingual mucosa combined with longitudinal preputial island flap onlay urethroplasty + tubularized incised plate glansplasty)versus the classic Bracka staged surgery for children with severe hypospadias.Methods:A retrospective analysis was conducted on clinical data of 75 children with proximal hypospadias who were treated at the Seventh Medical Center of PLA General Hospital from March 2017 to June 2022. Of these patients, 31 cases (15 cases penoscrotal type and 16 cases perineal type) were underwent the Bracka two-stage surgery with a median age of 38 months (24.0, 44.5) and 44 cases underwent the Hui-Jing one-stage procedure (23 cases penoscrotal type and 21 perineal type) with a median age of 40.5 months (20.75, 90.5). The length of urethral plate defect after correction of penile curvature was (4.30±0.84)cm in the Bracka group and (4.56±0.79)cm in the Hui-Jing group, which also showed no significant difference.There was no statistically significant difference of the median age and the position of preoperative urethral opening between the two groups( P=0.47, P=0.74). The first stage of Bracka repair consists of orthoplasty and urethral bed substitution with free preputial graft. After 6 months, the urethral plate created from free graft was tabularized to form neourethra; Hui-Jing procedure group used the free lingual mucosal as urethral plate substitution, then we conducted longitudinal preputial island flap Onlay and Snodgrass phalloplasty. The incidence of postoperative urethral fistula, urethral stricture and urethral diverticulum was compared between the two groups of cases and the difference in efficacy between the two procedures was assessed. Results:Among the 75 patients included in the study, there was no statistically significant difference in age or location of urethral meatus between the Bracka and Hui-Jing groups. In Bracka group, 9 cases of urethral stricture (29.0%), 6 case of urethral fistula (19.4%), and 2 cases of urethral diverticulum (6.5%) occurred after surgery, while 12 cases of urethral fistula (27.3%) and 3 case of urethral fistula (6.8%) occurred in the Hui-Jing group. No urethral stricture occurred in Hui-Jing group. There was no statistically significant difference in overall incidence of complications between the two groups [17/31(54.8%) vs.15/44(34.1%), P=0.12]. The incidence of urethral fistula and urethral diverticulum show no significant differences between two groups(19.4% vs 27.3, P=0.61, 6.5% vs. 6.8%, P=0.13). The number of operation in Bracka group was (2.68±1.03) and the hospitalization cost was (12 984.63±3 808.15) Yuan, while the number of operation in Hui-Jing group was (1.36±0.53) and the hospitalization cost was (8 490.54±3 136.84) Yuan. Conclusions:The Hui-Jing one-stage procedure can be used for the surgical treatment of children with severe hypospadias. There is no urethral stricture happened in Hui-Jing group, while the general complication incidence and incidence of urethral fistula and diverticulum show no differences.

Objective:To evaluate the safety and effectiveness of the model repair strategy for preputial defect in hypospadias surgery.Methods:From February 2017 to December 2022, 59 children in our hospital with an average age of (6.9±3.2) years were retrospectively analyzed. All of them were children with multiple failed hypospadias operations. According to the condition of penile scrotum skin, different methods of penile skin reconstruction were selected. Among them, 20 patients underwent penile skin flap reconstruction with simple foreskin and multiple small incision reduction, 22 patients with penile and scrotal transposition underwent penile lateral scrotum flap to complete ventral penis coverage, and 12 patients underwent middle scrotum flap with pedicled flap to cover ventral urethra. The penis was covered by inferior epigastric artery perforator flap in 5 patients.Results:The wound healed completely one week after the operation and no obvious scar formation was observed. The ventral flap of the penis was covered by the lateral scrotal flap of the penis, and no flap necrosis and wound infection were observed. The ventral urethra was covered with pedicled skin flap in the middle scrotal suture. The flap survived without scrotal hematoma. The inferior epigastric artery perforator flap was used to cover the patients with penile defect, all the flaps survived, and no complications such as wound infection and abdominal hernia occurred. No urethral fistula or urethral diverticulum was reported in all the patients. Urethral stricture occurred in 1 case of scrotal suture pedicled flap group and 1 case of lateral penis scrotal flap group, which was cured after expansion. One case with small incision and one case with lateral scrotal skin were cured after secondary repair by Mathieu method.Conclusions:For children with a history of multiple hypospadias operations, coverage of ventral skin defects of the penis is essential to reduce complications and obtain good appearance. This study summarized four effective strategies for covering penile defect from simple to complex. The small incision was used to reduce the expansion of all flaps. The lateral penile scrotal flap is more suitable for patients with penile scrotal transposition. The pedicled flap of scrotal suture and inferior superficial artery perforator flap are suitable for the repair of larger defect area.

Objective:To explore the effect of systematic diagnosis and treatment model based on new classification on primary hypospadias.Methods:The data of 689 patients with primary hypospadias admitted to Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March 2010 to June 2021 were retrospectively analyzed. Of all, 349 cases from March 2010 to June 2016 were treated with traditional treatment methods, and 340 cases from July 2016 to June 2021 were treated with systematic diagnosis and treatment model based on new hypospadias classification. Traditional treatment group of patients according to the European Society of Urology (EAU) guide classification, were divided into the distal-anterior type (located on the glans or distal shaft of the penis), intermediate-middle type (penile) and proximal-posterior type (penoscrotal, scrotal, perineal). For distal type, tubularized incised plate (TIP) or dorsal inlay urethroplasty (Inlay) was performed. Patients with intermediate-middle type underwent Inlay, and patients with proximal-posterior type underwent Bracka staging. In the systematic diagnosis and treatment group, hypospadias was reclassified into distal type (located on the glan or in the first third of the shaft of the penis), junctional type (the back two-thirds of the shaft of the penis and the base of the penis), and proximal type (scrotum or perineum). For distal type, TIP or Inlay was used. Patients with junctional type were treated with urethroplasty with union free graft and local flap method (Montage). Patients with proximal type were treated with Montage or Bracka staging. Patients with testicular volume <0.8 ml and glans width <1.0 cm were treated with human chorionic gonadotropin (HCG) before surgery. There were 349 patients in the traditional group, with an average age of (18.58±7.59) months. There were 157 cases of distal-anterior type, 47 cases of intermediate-middle type and 145 cases of proximal-posterior type. There were 181 cases with penile curvature < 30° and 168 cases with penile curvature ≥30°. There were 340 cases in the systematic diagnosis and treatment group, with an average age of (18.94±6.05) months. According to EAU classification, 160 cases were distal-anterior type, 42 cases were intermediate-middle type and 138 cases were proximal-posterior type. There were 197 cases with penile curvature < 30° and 143 cases with penile curvature ≥30°. There was no significant difference in the above indicators between the two groups ( P>0.05). The surgical methods, incidence of postoperative complications and the time of hospital stay between the two groups compared. The changes in penis size and testis volume before and after the use of hormones in the systematic treatment group were compared. Results:In the traditional group, 139 patients underwent TIP, 65 patients underwent Inlay, and 145 patients underwent Bracka staging. In the systematic diagnosis and treatment group, 187 cases were reclassified as distal type (153 cases underwent TIP and 34 cases underwent Inlay). Of the 69 cases of junctional type, 10 cases underwent Inlay, and 59 cases underwent Montage. Of the 84 cases of proximal type, 77 cases underwent Montage, and 7 cases underwent Bracka staging. There was significant difference between the two groups ( P<0.01). In the traditional group, there were 31 cases of urinary fistula (8.9%), 43 cases of urethral stricture (12.3%), 21 cases of urethral diverticulum (6.1%), 45 cases of penile recurvature (12.9%), and the total incidence of complications was 40.1% (140/349). There were 19 cases of urinary fistula (5.6%), 28 cases of urethral stricture (8.2%), 15 cases of urethral diverticulum (4.4%) and 24 cases of penile recurvature (7.1%) in the systematic diagnosis and treatment group. The total incidence of complications was 25.3%(86/340). There were statistically significant differences in the incidence of the above complications between the two groups ( P<0.05). There was a significant difference in the duration of hospital stay between the traditional group and the systematic diagnosis and treatment group [(4.3±1.2) d vs. (1.5±0.5) d, P=0.01]. The width of glans penis after HCG treatment was (1.35±0.14) cm, which was significantly higher than that before HCG treatment [(0.96±0.24) cm, P=0.03]. The length of penis [(2.55±0.19) cm vs. (2.29±0.16) cm] and the volume of testis [(0.76±0.24) ml vs. (0.64±0.15) ml] were not significantly different from those before treatment ( P>0.05). Conclusions:The new classification has clarified the choice of surgical methods, avoiding the amplification of surgical indications. The systematic diagnosis and treatment model based on new classification has significantly improved the treatment effect of hypospadias and effectively reduced postoperative complications. It provides an optional diagnosis and treatment model for hypospadias.
摘要
@#Introduction: Hypospadias is a condition when the urethra distal opens on the bottom of the penis and has a ventral penile curvature. Hypospadias is the second most frequent genital birth abnormality in boys after cryptorchidism. Surgery is the standard treatment of choice and has a significant risk problem. There are many surgical procedure complications, especially in appearance and function. This article discusses the appropriate operative management and the best long-term outcome. Methods: The data was culled and selected from the ten years of full-text English publication (2012-2022) utilizing the PubMed and Google Scholar databases. Meta-analyses (PRISMA) paradigm and PICO investigation of management techniques and long-term outcomes in clinical and randomized clinical trials. Result: From 149 search articles, 7 met the inclusion criteria. The gland penis size and the meatal location did not affect the outcome of the surgical technique. However, 58/432 patients required reoperation, and 61(13%) had urethroplasty complications (UC), although not statistically significant (OR 0.8, 95% CI: 0.7-0.9). Testosterone is advised for small penises, narrow glands, thin urethral plates, and proximal hypospadias (67 vs. 87%). Preoperative antibiotics reduce the incidence of infection (17/150 repairs), tubularized incised plate (TIP), and the stent is recommended. Conclusion: The recommended strategies are good perioperative treatment, including antibiotics, testosterone treatment, surgery ages (6-18 months), tubularized incised plate (TIP) technique, and stent postoperative.
摘要
Transperineal urethral anastomosis is currently an important treatment method for urethral stricture after pelvic fracture. After failure, this approach is still the main remedial operation. There is often a long segment atretic between the proximal and distal urethra in patients undergoing reoperation, and it is difficult to achieve tension-free anastomosis by simply pulling the proximal and distal ends, which is one of the important reasons for urethral anastomosis failure. This paper summarizes the failure factors of urethral repair surgery, the choice of reoperation, intraoperative details and answers to common difficult problems, in order to promote the theory and technical level of reconstructive urethral surgeons.

摘要
As an optional method for the treatment of hypospadias, free tube graft urethroplasty has been applied in some centers in recent years. It has the advantages of convenient urethra materials, high freedom of surgery, and satisfactory urine flow and appearance, but there are fewer reported cases and many complications. Therefore, it is recommended to be used cautiously. This paper summarizes the experience of 497 cases of free surgical surgery based on Buck fascia reconstruction, including key points such as full correction of penile lower curvature, no tension-free urethra, long-inclined plane anastomosis, and reliable coverage enhancement.

【Objective】 To investigate the penile appearance, sexual function, psychological status and related influencing factors of adult patients who underwent hypospadias repair surgery in their minors, so as to provide reference for the diagnosis, treatment and prognosis of hypospadias. 【Methods】 This study included 50 adult hypospadias patients who underwent urethroplasty in our hospital during May 2005 and Aug. 2018. The present appearance, sexual function and psychological status were evaluated. The correlation and consistency between hypospadias objective scoring evaluation (HOSE) and pediatric penile perception score (PPPS) were analyzed. Factors affecting the results were determined with univariate and multivariate regression analysis. 【Results】 The satisfaction rate of HOSE was significantly correlated with the urethral length and complications (P=0.024, P=0.033). The satisfaction rate of PPPS was significantly correlated with the number of urethral operations and postoperative complications (P=0.041, P=0.023). There was a weak correlation between HOSE and PPPS (r=0.291, P=0.040), but almost no consistency (Kappa=0.2, P=0.107). Sixty percent of the patients paid attention to the ventral appearance of penis, whose dissatisfaction rate of PPPS was higher than those who did not pay attention to the ventral appearance of the penis (19/30 vs. 6/20, P=0.021). Patients with multiple operations (>1), postoperative complications or unsatisfactory penile appearance were more likely to have inferiority complex (52.6% vs. 22.6%, P=0.029; 59.1% vs.14.3%, P=0.001;61.5% vs. 24.3%, P=0.015). Multivariate regression analysis showed that dissatisfaction with the appearance of the penis was an independent risk factor for patients’ perception of their own physical defects. Among the patients who believed that they had physical defects, the percentage of patients with grade IV penile erectile hardness was significantly lower than that of those who denied they had physical defects (9/17 vs. 27/33, P=0.047). 【Conclusion】 The undesirable postoperative penis appearance is likely to have a negative impact on patients’ long-term psychological state, which might further damage the sexual function in adulthood. Surgeons should pay attention to the penile appearance during the conduction of hypospadias repair.
摘要
Hypospadias is a common congenital malformation in the male urethra and external genitalia, which can be successfully treated with surgery. Various surgical treatments are available. Based on the repair criteria for restoring function and appearance, surgical treatments require the complete correction of the penile curvature, repair of the urethra to the head of the penis, and acquisition of a fissure-like opening. The local anatomical characteristics of hypospadias should be taken into consideration to formulate an individualized surgical treatment plan.

【Objective】 To explore the efficacy of Mathieu combined with tongue-shaped flap covering in children with distal hypospadias and micropenis head deformity. 【Methods】 The clinical data of 72 patients with distal hypospadias complicated with micropenis treated during Jan.2018 and Jun.2021 were retrospectively analyzed, including 35 patients who underwent modified Mathieu combined with tongue-shaped flap and external urethral orificium (study group), and 37 patients who underwent traditional Mathieu (control group). Urethral stricture, urethral fistula, urethral diverticulum and penile head cleft were compared between the two groups. 【Results】 Urinary fistula occurred in 2 cases (5.27%) and 9 cases (24.32%) in the study group and control group, respectively, the incidence being much lower in the study group (P=0.028). Urethral stricture occurred in 1 case (2.86%) and 1 case (2.70%) in the study group and control group, respectively; penile head dehiscence in 1 case (2.86%) and 3 cases (8.11%); urethral diverticulum in 0 case (0%) and 2 cases (5.41%). There were no significant differences between the two groups in the incidence of urethral stricture, urethral dehiscence and urethral diverticulum (P>0.05). 【Conclusion】 Mathieu combined with tongue-shaped flap covering to treat children with distal hypospadias with micropenis head deformity can reduce the incidence of postoperative complications, achieve high surgical satisfaction and appearance satisfaction in the first phase, reduce harm caused by surgery, and promote patients’ psychological health.

Objective:To summarize the ideal strategy for the treatment of female hypospadias.Methods:The data of 12 female patients with hypospadias admitted to the Sixth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine from December 2011 to December 2019 were retrospectively analyzed. The patients was (31.0±16.6) years old (7-67 years old). Among them, 3 cases had a history of pelvic fracture trauma, 3 cases had a history of birth trauma, and the remaining 6 cases had no history of trauma and surgery. Among them, there were 6 cases of congenital hypospadias and 6 cases of acquired hypospadias. The clinical manifestations were urinary incontinence in 6 cases and dysuria in 6 cases. Examination of the normal position of the external opening of the genital urethra did not show the opening of the urethra, but moved down to different parts of the anterior wall of the vagina. All patients underwent urethral lengthening. For congenital hypospadias, the urethral plate is used to cut the coiled tube during the operation to prolong the urethra. For acquired hypospadias, the stenotic urethra was enlarged and lengthened with a labial pedicled flap coil. The subcutaneous fat pad of the labia majora was mobilized and transferred to the outside of the newly constructed urethra to prevent the occurrence of urethro-vaginal fistula and increase the pressure of the urethra. Five patients with significant urinary incontinence underwent bladder neck reconstruction at the same time. Anatomical success of the procedure was defined as the appearance of a normal-shaped external urethral opening beneath the clitoris. Functional success was defined as the absence of moderate to severe urinary incontinence after surgery, and the maximum urinary flow rate was >15ml/s during the 12-month follow-up period.Results:All operations were successfully completed. All patients had no perioperative complications, and were followed up for 18-96 months, with an average of 57.3±32.5 months. All patients were able to urinate spontaneously after operation, 4 cases of urinary incontinence disappeared, and 2 cases improved significantly; 4 cases of patients with strenuous urination urinated smoothly. The remaining 2 cases still complained of dysuria after operation, which was solved by subsequent urethral dilatation. The anatomical repair success rate was 100.0%(12/12) and the functional success rate was 83.3% (10/12).Conclusions:Urethral lengthening is an effective method for female hypospadias. The pedicled fat pad helps to increase urethral pressure and prevent fistulas. For female patients with hypospadias and severe urinary incontinence, bladder neck reconstruction is an ideal method. of the technique.

El hipospadias es la localización anormal del meato urinario y es la malformación de genitales externos más frecuentemente diagnosticada. El diagnóstico prenatal es posible mediante ecografía sistemática desde la semana 20 de gestación, siendo más fácil su diagnóstico en el tercer trimestre. Las formas leves suelen ser aisladas, familiares o asociadas a disfunción placentaria o restricción de crecimiento intrauterino, mientras que las formas más graves presentan hasta un 30% de asociación a defectos fetales, anomalías cromosómicas/genéticas o anomalías del desarrollo sexual. La tríada para el diagnóstico ecográfico prenatal consiste en curvatura ventral del pene, anomalía del prepucio dorsal y punta del pene roma. La valoración de la uretra durante la micción y el aspecto del chorro miccional son de gran utilidad para clasificar el defecto. Cuando se diagnostica hipospadias peneano o escrotal es aconsejable realizar una amniocentesis para estudio genético fetal y valorar otros signos de adecuada virilización, como el descenso testicular a partir de la semana 27. El seguimiento tras el parto debe ser multidisciplinario, incluyendo urólogo y endocrinólogo infantil. En hipospadias leves el pronóstico es bueno con reparación quirúrgica en el primer año de vida, pero las formas graves pueden presentar un reto mayor para su corrección funcional y estética.
Hypospadias refers to the abnormal location of the meatus; it is the most common genital malformation detected in the fetus and newborn. Prenatal diagnosis is feasible from 20 weeks onwards with routine ultrasound; however, it is easier to diagnose during the third trimester of pregnancy. Mild defects are usually isolated, familiar o related to placental disfunction or intrauterine growth restriction, while the severe hypospadias are associated to other fetal defects, genetic or chromosomal abnormalities or disorders of sex development. In about 30% of cases. The triad of ultrasound findings prenatally is ventral curvature of the penis, redundant dorsal foreskin and blunt distal penis. The identification of the urethra during the micturition and the direction of the urinary stream help in the classification of the defect. When severe hypospadias is detected, the recommendation is to perform genetic amniocentesis and search for other ultrasound findings related to poor virilization in the fetus, as testicular descent after 27 weeks of gestation. Postnatal follow up should be multidisciplinary including infantile urologist and endocrinologist. The prognosis in distal hypospadias is usually good following surgical repair, however in severe cases surgical interventions may be more challenging in order to obtain satisfactory outcome in terms of function and esthetic.

Background:Hypospadias is one of the commonest congenital anomaly in boys which requires either a single stage repair or staged repair. The success of the procedure depend upon the type, anatomy, experience of the surgeon, method of repair and preoperative hormonal stimulation. Aim: The aim of the study was to evaluate the various preoperative factors responsible for outcome of single stage repair in distal penile, mid penile and proximal penile hypospadias. Methods: There were 48 patients in this observational study which were divided into two groups. Group A comprised of 24 patients with glanular and coronal hypospadias while Group B comprised of 16 patients with distal penile, 5 mid penile and 3 proximal penile types with minimal chordae. All the 24 (50%) patients in group A underwent meatal advancement and glanuloplasty incorporated (MAGPI) repair while in group B 15 (31.25%) patients underwent Tabularized Incised Plate (TIP) repair and 9 (18.75%) patients underwent combined TIP and Mathieu抯 repair. Results: Overall operative success rate observed in the study was 41 (85.41%) patients. In 7 (14.58%) patients urethrocutaneous fistula as a major complication occurred which included 1 patient in Group A and 2 patients with Distal Penile Hypospadias (DPH), 2 patients with Mid Penile Hypospadias (MPH) and 2 patients with Proximal Penile Hypospadias (PPH) in Group B. In 2 (4.16%) patients, mild meatal stenosis was noted which settled with meatal dilatation. Urethrocutaneous fistula (UCF) disappeared in 2 (4.16%) patients on follow up with regular urethral dilatation. Conclusion: MAGPI is the ideal procedure for glanular/coronal hypospadias. For distal penile hypospadias, TIP alone or combined TIP and Mathieu抯 repair gives equally good results. Preoperative testosterone therapy reduces the incidence of complications in a single stage hypospadias repair.
