Ipsilateral and contralateral patent processus vaginalis in pediatric patients with a unilateral nonpalpable testis / 亚洲男科学杂志(英文版)

This study aimed to investigate the incidence of patent processus vaginalis (PPV) in pediatric patients with a unilateral nonpalpable testis and explore the associated factors. From May 2014 to April 2017, 152 boys who were diagnosed with a unilateral nonpalpable testis and underwent laparoscopy in Shanghai Children's Hospital (Shanghai, China) were included in this study. The data were collected and reviewed, and the results were analyzed regarding the age at operation, side, development, and position of the nonpalpable testis. The mean age of the patients was 2.6 (standard deviation: 2.3) years. The testis was absent in 14 cases, nonviable in 81 cases, and viable in 57 cases. The incidence of PPV was 37.5% (57 of 152) on the ipsilateral side and 16.4% (25 of 152) on the contralateral side. The ipsilateral PPV was more prevalent when the nonpalpable testis occurred on the right side ( P < 0.01). Besides, patients with a viable testis had a greater incidence of ipsilateral PPV than those with a nonviable or absent testis ( P < 0.01). Moreover, this rate was the highest when the testis was in the abdominal cavity and the lowest when the testis was in the scrotum (both P < 0.01). However, the incidence of contralateral PPV was independent of all the factors. In conclusion, in children with a nonpalpable testis, the incidence of an ipsilateral PPV was significantly related to the side, development, and position of the testis, while it was independent of these factors on the contralateral side.

The effect of scrotal versus inguinal orchiopexy on the testicular function of children with clinically palpable, inguinal undescended testis: a randomized controlled trial / 亚洲男科学杂志(英文版)

To compare the impact of the scrotal vs inguinal orchidopexy approach on the testicular function of infants with cryptorchidism, a randomized controlled trial was conducted involving boys who were 6-12 months old at surgery and were diagnosed with clinically palpable, inguinal undescended testis. Between June 2021 and December 2021, these boys at Fujian Maternity and Child Health Hospital (Fuzhou, China) and Fujian Children's Hospital (Fuzhou, China) were enrolled. Block randomization with a 1:1 allocation ratio was employed. The primary outcome was testicular function assessed by testicular volume, serum testosterone, anti-Müllerian hormone (AMH), and inhibin B (InhB) levels. Secondary outcomes included operative time, amount of intraoperative bleeding, and postoperative complications. Among 577 screened patients, 100 (17.3%) were considered eligible and enrolled in the study. Of the 100 children who completed the 1-year follow-up, 50 underwent scrotal orchidopexy and 50 underwent inguinal orchidopexy. The testicular volume, serum testosterone, AMH, and InhB levels in both groups increased markedly after surgery (all P < 0.05), but there were no apparent differences between groups at 6 months and 12 months after operation (all P > 0.05). No differences between the scrotal and inguinal groups were noted regarding the operative time ( P = 0.987) and amount of intraoperative bleeding ( P = 0.746). The overall complication rate (2.0%) of the scrotal group was slightly lower than that of the inguinal group (8.0%), although this difference was not statistically significant ( P > 0.05). Both scrotal and inguinal orchiopexy exerted protective effects on testicular function in children with cryptorchidism, with similar operative status and postoperative complications. Scrotal orchiopexy is an effective alternative to inguinal orchiopexy in children with cryptorchidism.

Testicular arteries anatomy applied to fowler-sthephens surgery in high undescended testis - a narrative review

ABSTRACT Objectives: In this review we will describe the testicular vessels anatomy and the implications of these vessels in surgical treatment of high undescended testis. Material and Methods: We performed a narrative review of the literature about the role of the testicular arteries anatomy in the treatment of high undescended testis. We also studied two human testes to illustrate the testicular vascularization. Results: Each testis is irrigated by three arteries: testicular artery (internal spermatic artery), a branch of the right aorta; deferential artery (vasal artery), a branch of the inferior vesicle artery that originates from the anterior trunk of internal iliac artery and cremasteric artery (external spermatic artery), a branch of the inferior epigastric artery. There are important communications among the three arteries with visible anastomotic channels between the testicular and deferential arteries. Conclusions: Laparoscopic transection of the testicular vessels by dividing the spermatic vessels (Fowler-Stephens surgery) is safe in patients with high abdominal testis due to the great collateral vascular supply between testicular, vasal and cremasteric arteries; also, two-stage Fowler-Stephens orchiopexy appears to carry a higher rate of success than the single stage approach.

Novel homozygous mutation in a colombian patient with persistent müllerian duct syndrome: expanded phenotype

ABSTRACT The anti-Müllerian hormone triggers the regression of uterus and fallopian tubes in male embryos; if there are problems in the synthesis or action of this protein, Müllerian structures persist in an otherwise phenotypic male. The most frequent clinical presentation of Persistent Mullerian Duct syndrome is cryptorchidism and inguinal hernia. The few cases reported in adults are incidental findings or inguinal hernias. However, we present an adult male with history of bilateral cryptorchidism with unsuccessful orchidopexy, who presents with a large abdominal mass with the finding of a seminomatous tumor and persistence of Müllerian structures, in whom the variant c.916delC (p.Leu306Cysfs*29) in the AMHR2 gene not previously reported was documented.

Clinical and socioeconomic factors associated with delayed orchidopexy in cryptorchid boys in China: a retrospective study of 2423 cases / 亚洲男科学杂志(英文版)

We investigated the associations of clinical and socioeconomic factors with delayed orchidopexy for cryptorchidism in China. A retrospective study was conducted on cryptorchid boys who underwent orchidopexy at Children's Hospital at Chongqing Medical University in China from January 2012 to December 2017. Of 2423 patients, 410 (16.9%) received timely repair by 18 months of age, beyond which surgery was considered delayed. Univariate analysis suggested that the laterality of cryptorchidism (P = 0.001), comorbidities including inguinal hernia/scrotal hydrocele (P < 0.001) or urinary tract disease (P = 0.016), and whether patients lived in a poverty county (P < 0.001) could influence whether orchidopexy was timely or delayed. Logistic regression analysis suggested that the following factors were associated with delayed repair: unilateral rather than bilateral cryptorchidism (odds ratio [OR] = 1.752, P < 0.001), absence of inguinal hernia or hydrocele (OR = 2.027, P = 0.019), absence of urinary tract disease (OR = 3.712, P < 0.001), and living in a poverty county (OR = 2.005, P < 0.001). The duration of postoperative hospital stay and hospital costs increased with the patient's age at the time of surgery.

Surgical correction of ectopic penis and scrotum associated with bilateral orchidopexy / Correção cirúrgica de pênis e escroto ectópicos associada à orquidopexia bilateral

ABSTRACT Ectopic penis is usually associated with penoscrotal transposition, and it is rarely observed in isolation. We report a surgical approach for an extremely rare case. A 10-year-old male patient with bilateral cryptorchidism and ectopic penis and scrotum in perineal area, with no penoscrotal transposition, representing an association not yet described in literature. A previous orchiopexy failed due to ectopic scrotum. By means of an inverted Y incision, the penis was mobilized and a perineal skin flap in form of a testicular sac was prepared. Finally orchiopexy was performed. The surgery was essential to treat cryptorchidism and to improve the self-image of the patient.

RESUMO O pênis ectópico geralmente ocorre associado à transposição peno-escrotal, sendo raro isoladamente. Relatamos uma abordagem cirúrgica para um caso extremamente raro. Tratava-se de paciente do sexo masculino, 10 anos, com criptorquidia bilateral e pênis e escroto ectópicos, na região perineal, sem transposição peno-escrotal, representando uma associação ainda não descrita na literatura. Orquidopexia prévia sem sucesso, devido à ectopia do escroto. Por meio de uma incisão em Y invertido, mobilizou-se o pênis e preparou-se um retalho da pele perineal em forma de bolsa testicular. Por fim, realizou-se a orquidopexia. A cirurgia foi fundamental para tratar a criptorquidia e promover ganho na autoimagem do paciente.

Patologias genitais masculinas em cirurgia pediátrica de manejo / Outpatient pediatric surgery of male genital pathologies

Objetivos: Diagnosticar e manejar patologias comuns do trato genital masculino. Métodos: Revisão da literatura do ano de 2011 ao 2017 em base de dados PubMed. Resultados: Hipospádia é a localização anômala do meato uretral. Seu diagnóstico é clínico. As indicações cirúrgicas são anormalidades funcionais e estéticas. Fimose é descrita como impossibilidade de retração do prepcio para exposição da glande peniana, sendo um evento fisiológico quando apresenta resolução espontânea. Nos casos patológicos, o tratamento é primeiramente realizado com corticoide tópico. Se falha, o tratamento é cirúrgico. Hidrocele é o acúmulo de líquido na bolsa escrotal. O diagnóstico é clínico e por transiluminação escrotal. A maioria dos casos regride espontaneamente até os 24-36 meses. A cirurgia é considerada padrão-ouro para hidrocele comunicante na criança. Criptorquidia é a falha na migração do testículo até a bolsa escrotal. Seu diagnóstico é clínico, através da palpação testicular bilateral. Caso os testículos não estejam presentes na bolsa escrotal até os 6 meses de idade, a cirurgia é imprescindível, pelo risco de infertilidade e malignização. Conclusões: É essencial que o médico generalista saiba reconhecer tais condições com o intuito de iniciar prontamente o tratamento adequado, evitando suas complicações.

Aims: Diagnose and manage common pathologies of the male genital tract. Methods: Literary review of the last 6 years in the PubMed database. Results: Hypospadia is an anomalous location of the urethral meatus. The diagnosis is clinical. Surgical indications are functional and aesthetic abnormalities. Fimosis is described as impossibility of retraction of the foreskin to expose the penile glans, it is a physiological event when it presents spontaneous resolution. In pathological cases, treatment is first performed with topical corticosteroids. If it fails, the treatment is surgical. Hydrocele is the accumulation of fluid in the scrotal sac. The diagnosis is clinical and scrotal transillumination. Most cases regress spontaneously up to 24-36 months. Surgery is considered gold standard in cases of communicant hydrocele in children. Cryptorchidism is the failure of the migration of the testis to scrotal sac. The diagnosis is clinical through bilateral testicular palpation. If the testicles are not present in the scrotal sac until 6 months of age, surgery is essential, due to the risk of infertility and malignancy. Conclusions: It is imperative that the general practitioner knows how to recognize such conditions in order to promptly initiate appropriate treatment, avoiding complications.

Early experience with laparoscopic management of nonpalpable undescended testes

Background: Nonpalpable undescended testes (NPT) constitute 20%­30% of undescended testes, and its management has been a challenge both in diagnosis and treatment. Worldwide, laparoscopy is the current gold standard of management. In Nigeria, the management of NPT has largely been by open surgery with consequent high morbidity. In Nigeria, the trend is changing from a largely open management with its attendant high morbidity, to laparoscopic management which is the current worldwide gold standard of care. Aim: This study aims to classify the laparoscopic features of NPT and determine the outcome of managed cases in our center. Methodology: Prospective data were collected from consecutive patients who had laparoscopy for NPT at the Paediatric Surgical Unit of Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria from June 2014 to July 2016. Results: A total of 15 patients with 23 testes were treated. There were eight patients with bilateral NPT; four had left and the remaining three right NPT. The age ranged from 1.2 to 29 years with a median of 5 years. Eleven out of the 22 internal inguinal rings were open. The position of the testes was canalicular (2), peeping (2), low abdominal (6), high abdominal (6), blind-ended vas (1), absent vas and vessels (5). No further intervention was needed for the six agenetic/atrophic testes. Standard open orchiopexy was done for the two canalicular testes. Eight testes were brought down by one stage laparoscopic orchiopexy while four were brought down by staged laparoscopic Fowler-Stephens procedure. Laparoscopic orchiectomy was done in two patients (a grossly dysmorphic testes [nubbin] and a high abdominal testis in a 29-year-old). Orchiopexy was successful in 11 out of 15 fixed testes. Of the unsuccessful ones, three testes were atrophic (volume less than what it was initially) while two were high scrotal (one testes has both complications). There was no conversion to open abdominal surgery. All patients were discharged within 24 h of surgery.Conclusion: Laparoscopy provides for a better management of NPT by combining diagnosis and intervention in the same sitting with a good success rate and minimal postoperative morbidity

Do retractile testes have anatomical anomalies?

ABSTRACT Objectives: To assess the incidence of anatomical anomalies in patients with retractile testis. Materials and Methods: We studied prospectively 20 patients (28 testes) with truly retractile testis and compared them with 25 human fetuses (50 testes) with testis in scrotal position. We analyzed the relations among the testis, epididymis and patency of the processus vaginalis (PV). To analyze the relations between the testis and epididymis, we used a previous classification according to epididymis attachment to the testis and the presence of epididymis atresia. To analyze the structure of the PV, we considered two situations: obliteration of the PV and patency of the PV. We used the Chi-square test for contingency analysis of the populations under study (p <0.05). Results: The fetuses ranged in age from 26 to 35 weeks post-conception (WPC) and the 20 patients with retractile testis ranged in ages from 1 to 12 years (average of 5.8). Of the 50 fetal testes, we observed complete patency of the PV in 2 cases (4%) and epididymal anomalies (EAs) in 1 testis (2%). Of the 28 retractile testes, we observed patency of the PV in 6 cases (21.4%) and EA in 4 (14.28%). When we compared the incidence of EAs and PV patency we observed a significantly higher prevalence of these anomalies in retractile testes (p=0.0116). Conclusions: Retractile testis is not a normal variant with a significant risk of patent processus vaginalis and epididymal anomalies.

A rare case of perineal hamartoma associated with cryptorchidism and imperforate anus: case report / Caso raro de hamartoma perineal associado a criptorquidia e ânus imperfurado: relato de caso

A full-term male neonate with anorectal anomaly and external perineal anomalies was referred to our service. Physical examination showed an epithelized perineal mass with cutaneous orifices, which had urine fistulization, hipotrofic perineal musculature, bilateral congenital clubfoot, hipospadic urethra, criptorquidy bilateral with nonpalpable testis and imperforate anus. A colostomy was constructed immediately after birth. The child underwent excision of perineal mass, bilateral orchidopexy, Duplay neourethroplasty and coloanal anastomosis at 3 months of age. The histopathological examination of the perineal mass revealed a hamartoma.

Recém-nascido a termo do sexo masculino encaminhado ao nosso serviço por anomalia anorretal e anomalias perineais externas. O exame físico revelou massa perineal epitelizada, com orifícios cutâneos que apresentavam saída de urina, musculatura perineal hipotrófica, pé torto congênito bilateral, uretra hipospádica, criptorquidia bilateral com testículos não palpáveis e ânus imperfurado. Logo após o nascimento, o paciente foi submetido à colostomia. Aos 3 meses de idade, a criança foi submetida à excisão da massa perineal, orquidopexia bilateral, neouretroplastia a Duplay e anastomose coloanal. A análise anatomopatológica da massa perineal indicou hamartoma.

Recurrence of acute myeloid leukemia in cryptorchid testis: case report / Recidiva de leucemia mieloide aguda em testículo criptorquídico: relato de caso

A 23-year-old male with a history of bone marrow transplant for acute myeloid leukemia. He presented a large mass in the right inguinal region 5 years ago. Upon physical examination, right-sided cryptorchidism was observed. The tumor markers alpha-fetoprotein and beta-HCG were within normalcy range and lactate dehydrogenase was raised. Computed tomography of the abdomen and pelvis revealed right testicular mass in contiguity with the inguinal canal to the ipsilateral retroperitoneum, associated with right hydronephrosis. Due to the risk of germ-cell tumor in undescended testicle, the patient underwent radical right orchiectomy. The pathological examination showed recurrence of acute myeloid leukemia in the testis. He was referred to oncology for adjuvant therapy. Our literature review found no similar cases described.

Paciente de 23 anos, masculino, com antecedente de transplante de medula óssea por leucemia mieloide aguda. Há 5 anos, apresentou volumosa massa em região inguinal direita. No exame físico, foi constatada criptorquidia à direita. Os marcadores tumorais alfa-fetoproteína e beta-HCG encontravam-se dentro da normalidade, e a desidrogenase láctica estava aumentada. A tomografia computadorizada de abdomen e pelve revelou massa testicular direita com contiguidade pelo canal inguinal, até o retroperitônio ipsilateral, associada a hidronefrose direita. Devido ao alto risco de neoplasia germinativa em testículo criptorquídico, o paciente foi submetido à orquiectomia radical direita, cujo anatomopatológico revelou recidiva de leucemia mieloide aguda em testículo. Foi encaminhado para oncologia para terapia adjuvante. Nossa revisão não revelou nenhum caso semelhante na literatura.

Orquidopexia videoasistida (OVA): ¿es la técnica de elección para una criptorquidia palpable difícil? / Video-Assisted orchidopexy (OVA): is it the technique of choice for difficult palpable undescended testicles?

Existe un grupo de pacientes con criptorquidias palpables en los que la liberación de los vasos espermáticos y el conducto deferente en el retroperitoneo por laparoscopía, facilitaría la orquidopexia abierta en un sólo tiempo y mejoraría el pronóstico de posición y vitalidad testicular a largo plazo. Presentamos nuestra experiencia inicial de pacientes tratados con esta técnica, a la que hemos denominado Orquidopexia Video Asistida (OVA).Estudio prospectivo entre agosto de 2011 y marzo de 2012 que incluyó 15 pacientes y 16 testículos. Se incluyeron criptorquidias canaliculares altas, “peeping testis” y re-operaciones. Se excluyeron pacientes que, en el examen bajo anestesia general, se palpó testículo en posición canalicular media o baja. En 8 meses se realizaron 9 OVA izquierdas, 5 derechas y 1 bilateral. La edad operatoria promedio de los pacientes fue de 3,7 años. El tiempo quirúrgico promedio fue de 55 minutos. El tiempo de seguimiento promedio fue de 9 meses (r6-14 meses). El seguimiento clínico ha mostrado posición normal y buena vitalidad testicular evaluada por tamaño testicular al examen físico en todos los pacientes. CONCLUSIONES: Los resultados clínicos preliminares son alentadores. Proponemos agregar OVA al algoritmo de tratamiento de las criptorquidias palpables.

There is a group of patients with palpable cryptorchidism in which releasing the spermatic vessels and the vas deferens in the retroperitoneum through laparoscopy, facilitates the open orquidopexy in a single time and improves the prognosis of testicular position and vitality on the long term. We report our initial experience of patients treated with this technique, which we called Video Assisted orchidopexy (OVA).Prospective study between August 2011 and March 2012, which included 15 patients and 16 testicles. High canalicular cryptorchidism, “peeping testis” and re-operations were included. We excluded patients who, on examination under general anesthesia, had a palpable canalicular testis in middle or low position. RESULTS: In a peroid of 8 months we performed 9 left, 5 right and 1 bilateral OVA. Mean age of the patients was 3.7 years. Mean operative time was 55 minutes. Average follow-up time was 9 months (r6-14 months). Clinical follow-up shows normal position and good vitality as assessed by testicular size at physical examination on all patients. Preliminary clinical results are encouraging. We propose adding OVA treatment algorithm palpable cryptorchidism.

Single scrotal incision orchiopexy - a systematic review

Objective To conduct a systematic review on single scrotal incision orchiopexy. Materials and Methods: A search was performed using Pubmed, through which 16 articles were selected out of a total of 133. The following conditions were considered exclusion criteria: other surgical methods such as an inguinal procedure or a laparoscopic approach, retractile testes, or patients with previous testicular or inguinal surgery. Results A total of 1558 orchiopexy surgeries initiated with a transcrotal incision were analyzed. Patients' ages ranged between 5 months and 21 years. Thirteen studies used high scrotal incisions, and low scrotal incisions were performed in the remainder of the studies. In 55 cases (3.53%), there was a need for inguinal incision. Recurrence was observed in 9 cases, testicular atrophy in 3, testicular hypotrophy in 2, and surgical site infections in 13 cases. High efficacy rates were observed, varying between 88% and 100%. Conclusions Single scrotal incision orchiopexy proved to be an effective technique and is associated with low rates of complications. .

Splenogonadal fusion and testicular cancer: case report and review of the literature / Fusão esplenogonadal e câncer testicular: relato de caso e revisão da literatura

A 36 year-old man after tests for assessing male infertility was diagnosed with primary infertility, bilateral cryptorchidism, nonobstructive azoospermia and discontinuous splenogonadal fusion. Carcinoma in situ was found in his left testicle, which was intraabdominal and associated with splenogonadal fusion. To our knowledge, this is the fourth case of splenogonadal fusion associated with testicular cancer reported. One should always bear in mind the possibility of this association for the left cryptorchid testicle.

Um homem de 36 anos, depois de ser submetido a exames para avaliação de infertilidade masculina, foi diagnosticado com infertilidade masculina primária, criptorquidia bilateral, azoospermia não obstrutiva e fusão esplenogonadal descontínua. Carcinoma in situ estava presente no testículo esquerdo, que tinha localização intra-abdominal e estava associado à fusão esplenogonadal. Esse é o quarto caso de fusão esplenogonadal associada a câncer testicular, segundo nossa avaliação. Deve-se sempre ter em mente a possibilidade dessa associação em testículos criptorquídicos à esquerda.

Evaluation of apoptotic genes expression and its protein after treatment of cryptorchid mice

Cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. The purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. To induce bilateral cryptorchid model, immature mice were anesthetized and a small incision was made in the abdominal skin and peritoneum, then fat pad at the upper end of testis was sutured to the peritoneum. Transcript level of Bax, Bcl-2 proper, p53 and survivin mRNA and protein were determined after performing the two treatment methods: surgical return of testis into scrotum [Exp1] and transplantation of spermatogonial stem cells with later orchidopexy [Exp2], performed 2 and 3 months after heat exposure, respectively. RT-PCR data showed decreased levels of p53 and Bax expression as well as decreased levels of Bcl-2 mRNA in treatment groups especially after transplantation compared with control group. The expression of survivin 140 was increased significantly after treatment, whereas that of survivin 40 was lower especially in the orchidopexy group. Immunohistochemistry staining showed that the intensity of Bax expression mainly was decreased in treated cryptorchid testis and rates of Bcl-2 were increased significantly, but expression of p53 and survivin proteins did not changed significantly after treatment. These observations suggest that cell-type-specific and many apoptotic systems control germ cell apoptosis after treatment of cryptorchidism

Findings concerning testis, vas deference, and epididymis in adult cases with nonpalpable testes

In this study, we aimed to state the relationship between testis, epididymis and vas deference, in adult cases with nonpalpable testis. Between January 1996 and December 2009, we evaluated 154 adult cases with nonpalpable testes. Mean age was 23 years (20-27 years). Explorations were performed by open inguinal incision, laparoscopy, and by inguinal incision and laparoscopy together on 22, 131 and 1 patient, respectively. Of all the unilateral cases, 32 were accepted as vanishing testis. In five of these cases, vas deference was ending inside the abdomen, and in the others, it was ending inside the scrotum. In the remaining 99 unilateral and 22 bilateral cases, 143 testes were found in total. Testes were found in the inguinal canal as atrophic in one case, at the right renal pedicle level with dysmorphic testis in one case, and anterior to the internal ring between the bladder and the common iliac vessels at a smaller than normal size in 119 cases. One (0.69 percent) case did not have epididymis. While epididymis was attached to the testis only at the head and tail locations in 88 (61.53 percent) cases, it was totally attached to the testis in 54 (37.76 percent) cases. There is an obviously high incidence rate of testis and vas deference anomalies, where epididymis is the most frequent one. In cases with abdominal testes, this rate is highest for high localised abdominal testes.

Causes of delay in proper treatment of patients with undescended testis

Undescended testis [UDT] is the most common endocrine disorder in male children. Delayed diagnosis and treatment of UDT lead to complications such as infertility, malignancy and testis rotation. The aim of this study was to evaluate the causes of delay in proper treatment of patients with undescended testis in our population. An observational, descriptive, cross sectional study of 143 male patients, who applied to Shahid Sadoughi University Hospitals for orchiopexy operation was performed. The maximum recommended age for orchiopexy was 18 months. The mean age at referral was 5.34 years. Only 44 [30.8%] cases were operated on before the age of 18 months. The most common reasons of delay in treatment were absence of early diagnose [42.5%], parent's unawareness of surgery necessity and its complications associated [33.7%] and parent's disregard [23.5%]. Only 19.6% of patients were diagnosed at born in the hospital. 49% of parents had the correct information for proper operation age and 40.6% of them had enough information about necessity of surgery and side effects of disease. Parent's literacy, place of living and type of cryptorchidism had no significant relation with delay diagnosis [p> 0.05]. These results revealed that late diagnosis by physician and lack of insight of parents are the main reasons in delayed diagnosis and treatment of UDT. Therefore, education of parents and careful physical examination of the babies at birth and regular follow-up until 18 months can prevent the delay in diagnosis
