Management of undescended testis.

PURPOSE OF REVIEW: Describe why this review is timely and relevant.Undescended testis, or cryptorchidism, is a common diagnosis encountered by pediatricians that requires timely collaboration with pediatric surgical specialists to optimize outcomes for these patients. As this topic continues to be heavily researched, it is imperative to understand current recommendations and emerging management options including new surgical techniques, as well as common pitfalls in care highlighted in the literature. RECENT FINDINGS: Describe the main themes in the literature covered by the article.This review primarily examines current practice in management including delays in surgical referral, with unnecessary imaging being a key factor that delays time to surgery. This review briefly discusses the diagnosis of undescended testis and the various surgical techniques used including the more recently proposed laparoscopic staged traction orchiopexy (Shehata technique). The ineffectiveness of hormonal therapy is also addressed. SUMMARY: describe the implications of the findings for clinical practice or research.This review emphasizes prompt evaluation and diagnosis of undescended testis to facilitate appropriately timed surgical intervention, which plays a major role in outcomes for these patients. Identifying patients at risk of delayed referral is an area of focus for improvement, along with better resource utilization with fewer imaging. Familiarization of surgical options can also facilitate better patient education and provider understanding of risks/benefits.

Diagnoses and Treatment of Acquired Undescended Testes: A Review.

Acquired undescended testes were once considered a sporadic disease. In recent years, reports suggest that they are not uncommon, with an incidence rate about 3 times that of congenital undescended testes. The etiology of acquired undescended testes remains inconclusive, clinical diagnostic standards are unclear, and treatment approaches are still controversial. There is ongoing debate about the mechanism of testicular ascent. The prevailing view is that acquired undescended testes occur due to the partial absorption of the gubernaculum, which forms part of the parietal peritoneum. The residual gubernacular fibers continuously pull on the spermatic cord, preventing the spermatic cord from elongating proportionately to somatic growth, leading to a re-ascent of the testis. Acquired undescended testes may increase the risk of testicular cancer, but this is still debated. The preferred treatment method is also controversial. However, surgical fixation has an immediate effect; no studies have proven that early surgery improves fertility in patients. The etiology of acquired undescended testes is closely related to the continuous pull of the residual gubernacular fibers on the spermatic cord, which prevents the cord from extending proportionately to body growth. There are no clear diagnostic standards for acquired undescended testes yet, and spontaneous descent is possible, so testicular fixation surgery may not be the preferred treatment method.

Common Pediatric Urologic Conditions: Contemporary Management of Cryptorchidism, the Retractile Testis, and Phimosis.

Undescended testis is the most common genital disorder identified at birth. Boys who do not have spontaneous descent of the testis at 6 months of age, adjusted for gestational age, should be referred to pediatric urology for timely orchiopexy. Retractile testes are at risk for secondary ascent of the testes and should be monitored by physical examination annually. If there is concern for ascent of the testis, pediatric urology referral is recommended. Most cases of phimosis can be managed medically with topical corticosteroids and manual retraction of the foreskin.

Hyperbaric oxygen treatment in bilateral orchiopexy and post-circumcision haematoma in a thrombocytopenic patient with Noonan syndrome.

Hyperbaric oxygen treatment (HBOT) can be utilised for necrotising soft tissue infections, clostridial myonecrosis (gas gangrene), crush injuries, acute traumatic ischaemia, delayed wound healing, and compromised skin grafts. Our case was a 17-month-old male patient with Noonan syndrome, idiopathic thrombocytopenic purpura, and bilateral undescended testicles. Haematoma and oedema developed in the scrotum and penis the day after bilateral orchiopexy and circumcision. Ischaemic appearances were observed on the penile and scrotal skin on the second postoperative day. Enoxaparin sodium and fresh frozen plasma were started on the recommendation of haematology. Hyperbaric oxygen treatment was initiated considering the possibility of tissue necrosis. We observed rapid healing within five days. We present this case to emphasise that HBOT may be considered as an additional treatment option in patients with similar conditions. To our knowledge, no similar cases have been reported in the literature.

Cryptorchidism Review for the Primary Care Provider.

Cryptorchidism, or undescended testes, is the most common disorder of the genitals seen at birth. Due to its high prevalence and short- and long-term sequelae, it is crucial that primary care providers are familiar with the appropriate management of cryptorchidism. This paper serves to review the embryology, diagnosis, management, and treatment of cryptorchidism with the goal of serving as a valuable reference for providers managing pediatric and neonatal urological issues in the primary care setting, using the American Urological Association's most recent guidelines on the subject. Importantly, it also serves as a review of the long-term consequences of cryptorchidism (even after repair) and reinforces the need for continued surveillance for complications throughout a patient's life.

Evaluation of Undescended Testes in Newborns: It Is Really Simple, Just Not Easy.

INTRODUCTION: The evaluation of the testicular position in newborns is important to ensure timely initiation of therapy. The aim of our study was to assess the reliability of a routinely performed screening examination. PATIENTS AND METHODS: Newborns were examined by a pediatrician between 48 and 72 h after birth. Boys with suspected cryptorchidism were double-checked by a pediatric urologist within 24 h. RESULTS: 1,181/2,353 children included in the study between June 2015 and December 2017 were male. Eight hundred sixty-one boys could be included in this analysis; 5.8% (n = 50) were diagnosed with undescended testis (UDT) by the pediatrician. 30/50 boys were double-checked at the Department of Pediatric Urology. Forty percent (20/50) were lost to follow-up. In 43% (13/30), the diagnosis could be confirmed. Three former studies had shown a relevant discrepancy in the results of the diagnosis of UDT made by health care providers and urologists/pediatric surgeons. To our knowledge, this is the first study evaluating the testicular position in male newborns in such a large prospective birth cohort study by physicians with ranging expertise within 1 day. CONCLUSION: Further treatment for UDT is based on clinical examination. Ours and previous studies can clearly show the various findings in boys suspected having UDT. Therefore, it is essential that the diagnosis is confirmed by a specialist before a therapy is initiated.

Effect of adjunctive hormonal therapy on testicular descent and spermatogenic function among children with cryptorchidism: a systematic review and meta-analysis.

OBJECTIVES: To systematically evaluate the effect of adjunctive hormonal therapy on testicular descent and spermatogenic function among children with cryptorchidism. METHODS: A comprehensive literature search of electronic databases up to February 21, 2019 was performed. Continuous data of fertility indices were evaluated using weighted mean difference (WMD) with 95% confidence interval (CI), while nominal data of fertility indices and the complete descent rates were analyzed by risk ratio (RR) with 95% CI. A fixed effect or random effect model was used. RESULTS: A total of 27 previous studies were included for the current analysis. Hormonal therapy increased complete testicular descent rate, reaching statistical significance (RR = 3.74; 95% CI, 2.78-5.04; P < 0.001). The success rate was 22.43%. A similar result was found in subgroup analysis of hormonal category and effect on unilateral or bilateral cryptorchidism. Studies reporting primary outcome as continuous data showed that cryptorchid males have significantly increased germ cell numbers per tubule (WMD = 0.10; 95% CI, 0.01-0.20, P = 0.032) after hormonal therapy. The nominal data of pooled studies showed no significant difference (RR = 1.62; 95% CI, 0.65-4.00, P = 0.298). In addition, a significant result was noted in the luteinizing hormone-releasing hormone (LHRH) therapy group but not in those undergoing human chorionic gonadotropin (hCG) treatment. CONCLUSIONS: Our findings have demonstrated that hormonal therapy can effectively increase the success rate of complete testicular descent, while some boys may benefit as regards improvement of the fertility index.

Undescended testes: What general practitioners need to know

BACKGROUND: Undescended testis (UDT) is a common condition, and parents often primarily present to general practitioners. Management in a timely fashion may reduce the risk of malignancy and infertility OBJECTIVES: The aim of this article is to summarise the key points of assessment and management of UDT in the primary care setting. By reviewing key definitions, such as undescended, retractile, ectopic and ascending testes, we aim to provide updated information for the ongoing management of these conditions. DISCUSSION: The exact pathophysiology of UDT is still an area of ongoing research, and there remains much controversy regarding the exact mechanisms leading to congenital and acquired UDT. Current evidence does not support the use of ultrasonography prior to referral. Hormone therapy has shown no significant benefit, and surgery remains the treatment of choice.

Barriers to implementation of guidelines for the diagnosis and management of undescended testis.

Cryptorchidism or undescended testis (UDT) is one of the most common genital disorders identified at birth. The gold standard for treatment in the US is to surgically bring the UDT into the scrotal sac. In 2014, the American Urologic Association (AUA) presented a guideline for evaluation and treatment of cryptorchidism. We reviewed some of the most recent domestic and international studies examining the results of implementing the AUA and similar guidelines for the diagnosis and management of UDT. In addition, we reviewed some of the more common barriers to the implementation of the AUA guidelines and offered recommendations on how to increase the rate of early detection of UDT, thereby increasing the rate of surgical correction at the appropriate age.

Poor prognosis of retroperitoneal mixed extragonadal germ cell tumors in an HIV-infected man with severe immunosuppression and bilateral cryptorchidism: a case report.

BACKGROUND: Nonseminomatous germ cell tumors (NSGCTs) represent one of the main groups of germ cell tumors (GCTs), and they have a more invasive course than seminomatous GCTs. Human immunodeficiency virus (HIV) positivity is considered to be a risk factor for testicular seminoma patients, but reports about HIV-infected individuals with NSGCTs are rare. CASE PRESENTATION: We report a case of a retroperitoneal mixed extragonadal germ cell tumor in an HIV-infected man who has been diagnosed with bilateral cryptorchidism since birth. A 30-year-old man presented with a large heterogeneously mixed echo mass located in the right lower abdomen according to an abdominal ultrasound; he was HIV-positive and had a low CD4 count of 70 cells/ml in the followed test, which suggested severe immunosuppression, and ultrasound-guided biopsy histology revealed a malignant yolk sac tumor of the testis. First, the patient received combination antiretroviral therapy; then, to relieve his symptoms, an exploratory laparotomy and retroperitoneal neoplasm resection under general anesthesia were performed for subsequent treatment. The postoperative histopathological examination indicated that the patient exhibited malignant mixed GCTs of the undescended testis that were composed predominantly of yolk sac tumors with foci of embryonal cell carcinoma and seminoma; It is a rare type in various GCTs, especially in HIV-infected patients. After the operation, the patient underwent computed tomography follow-up scans at 1 week and 2 weeks, and the results showed that the size of the right inguinal mass gradually increased, which suggested a poor outcome. To limit the growth of the tumors, right inguinal mass resection under local anesthesia was performed 17 days after the initial operation, and pathological examination revealed mixed GCT metastasis. Subsequently, the patient received salvage chemotherapy with a regimen of cisplatin, etoposide, and ifosfamide. Unfortunately, the patient died 1 week after the first cycle of chemotherapy because of severe immunosuppression, a low platelet count and cancer cachexia. CONCLUSIONS: Because of severe immunosuppression, the treatment of advanced extragonadal NSGCTs in an HIV-infected patient resulted in a poor prognosis. This outcome should be considered in further research, and appropriate management for achieving long-term survival needs to be established.

[Acquired undescended testes: treatment and consequences for future fertility]. / Verworven niet-scrotale testis.

1-3% of boys develop an acquired undescended testes (UDT), meaning that the testes cannot be returned into the scrotum after previously having been located in a stable scrotal position. Fertility issues for patients with acquired UDT are comparable to those for patients with congenital UDT. Hypothetically speaking, patients with acquired UDT are at lower risk of testicular cancer than patients with congenital UDT. The appearance of an asymmetrical scrotum, which is associated with UDT, may negatively influence quality of life. Over 50% of the acquired UDTs will spontaneously descend at the start of puberty, thereby justifying conservative management of the condition. Orchidopexy directly after diagnosis does not have any advantages over awaiting spontaneous descent until puberty when fertility in later life of patients with unilateral acquired UDT is concerned; however, it may be beneficial in bilateral acquired UDT.

Optimal Management of Undescended Testis in Boys with Cerebral Palsy. A Debate.

Cerebral palsy is a rare condition following injury of the developing brain and including nonprogressive neurological disorders, spasticity, intellectual impairment and others. Boys with cerebral palsy have a high incidence of undescended testis. Although the motives for treatment (infertility, cancer prevention, psychological aspects, testicular torsion) are not different in boys without neurological impairment, the decision-making process in boys with cerebral palsy is very difficult. Besides medical and surgical arguments the discussion involves challenging ethical issues.

A critical review of recent clinical practice guidelines on management of cryptorchidism.

BACKGROUND/PURPOSE: Limited efforts have been made in assessing the qualities of clinical practice guidelines (CPGs) on cryptorchidism (UDT). This appraisal aims to determine the quality of recent CPGs on the management of UDT. METHODS: After systematic literature search, all English-based CPGs providing recommendations for the management of UDT from 2012 to 2017 were reviewed. Using the AGREE II (Appraisal of Guidelines and Research Evaluation) instrument, eligible CPGs were independently appraised by 5 reviewers. Domain scores were calculated and summarized. Intraclass coefficient (ICC) was used to assess for interrater reliability. RESULTS: Five CPGs from Agency for Healthcare Research and Quality (AHRQ), American Urological Association (AUA), British Association of Pediatric Surgeons/British Association of Urologic Surgeons (BAPS/BAUS), Canadian Urological Association (CUA), and European Association of Urology/European Society for Pediatric Urology (EAU/ESPU) were assessed. There was a solid agreement (ICC: 0.749) among the 5 reviewers (p<0.001). Most recommendations for diagnostic and treatment approaches were consistent across CPGs. For most guidelines, the domains of 'clarity of presentation,' 'scope and purpose,' 'stakeholder involvement,' and 'rigor of development' were high, while 'applicability' was low. CONCLUSION: Most guidelines on UDT score high in the AGREE II domains and have consistent recommendations. To improve the 'applicability' domain, future guidelines should improve on aspects that facilitate implementation of the recommendations. TYPE OF STUDY: Systematic review. LEVEL OF EVIDENCE: V (based on the lowest level of evidence utilized by the assessed guidelines).
