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...

PURPOSE: To discuss an optimal surgical approach for impalpable testis in children, our own treatment results and those reported in the literature were reviewed. MATERIALS AND METHODS: Seventy-two impalpable testes were diagnosed in 68 patients: unilateral in 64 patients and bilateral in 4 patients. All patients underwent surgical exploration at the ages of 6 to 140months (median, 15months). The inguinal canal was initially explored, and abdominal exploration was performed with laparoscopy when an extra-abdominal testis was not identified...

Undescended testis persistently present at the 6th month of life in a term born boy should be treated, with the aim of bringing them to a scrotal position until the 12th month of life. Acquired undescended testes has to be looked for actively and treated at the earliest possible after diagnosis, that might be deferred due to a lack of attention and less access to a regular physical exam in older boys as opposed to infants.

Undescended testis (UDT) occurs when something goes wrong with testicular descent from high in the abdominal cavity to the scrotum. Normal descent occurs in two steps, with the transabdominal phase controlled by a new testicular hormone, insulin-like hormone 3, and the inguinoscrotal phase controlled by androgens. The latter phase requires a complex process of migration from the inguinal abdominal wall to the scrotum and is commonly defective, leading to the high incidence (2-4%) of UDT at birth. The clinical examination of babies and infants aims to confirm the persistence of congenital UDT by 3-6 months, so surgery can be optimally timed at 6-12 months...

OBJECTIVE: Diagnostic laparoscopy is the gold standard in the algorithm of nonpalpable testis. Testicular tissue is examined and treatment is planned accordingly. In this study we reviewed the place of diagnostic laparoscopy, and evaluated the results and effectiveness of laparoscopy in the diagnosis and management of nonpalpable testis. MATERIAL AND METHODS: Children who had diagnostic laparoscopy for nonpalpable testes were included in the study. Physical examination results, ultrasonography (USG) reports, age at surgery, laparoscopic and inguinal exploration findings, surgical procedures, orchiopexy results, early and late-term complications were evaluated...

Undescended testis (UDT) is the most common disorder of sexual development in boys and affects 3.5% of male newborns. Although approximately half of newborn UDTs descend spontaneously, some boys develop an ascending testis later in childhood. Recent guideline recommendations advocate orchiopexy by 18 months of age to maximize potential for fertility and perhaps reduce the risk for testicular carcinoma in the future. For palpable testes, a standard inguinal approach is appropriate. However, the prescrotal approach is often effective for low inguinal testes and reduces surgical time and patient discomfort with an equivalent success rate in boys with an ascending testis...

OBJECTIVE: To review the differences between normal, retractile, ectopic, ascended, and undescended testes and to describe the optimal way to perform a testicular examination to distinguish one from the other, as well as to demonstrate that ultrasound imaging is not necessary and to clarify when to consider specialist referral. SOURCES OF INFORMATION: This paper is based on selected findings from a MEDLINE search on undescended testes and orchiopexy referrals, and on our experience at the Urology Clinic at the Children's Hospital of Eastern Ontario in Ottawa, including review of referrals to our clinic for undescended testes and the resultant findings of normal variants versus surgical cases...

Undescended testes (UDT), where one or both testes fail to migrate to the base of the scrotum, can be congenital (2-5% of newborn males) or acquired (1-2% of males). The testis may be found in any position along its usual line of descent. Cryptorchidism affects the developing testicular germ cells and increases the risk of infertility and malignancy. Clinical management aims to preserve spermatogenesis and prevent the increased risk of seminoma. Examination to document the testicular position will guide the need for imaging, medical management and the surgical approach to orchidopexy...

PURPOSE OF REVIEW: This article summarizes the latest evidence on the risk factors, management and outcomes of undescended testes (UDTs). RECENT FINDINGS: UDTs remain common, with increasing evidence that acquired UDT or the ascending testis syndrome should be considered part of the spectrum of this disease. Prompt diagnosis and early referral for surgical evaluation and treatment would seem most likely to result in an optimal functional and cosmetic outcome. Hormonal treatment, rather than orchidopexy, remains popular in some centers, despite a lack of good evidence to support its efficacy, although it may have an important adjunct role in optimizing fertility...

PURPOSE: The purposes of this study were to demonstrate the usefulness of laparoscopy in intraabdominal testicle (IAT) and to determine factors associated with diminished size during the final outcome after laparoscopic orchidopexy. METHODS: This is a retrospective analysis of consecutive patients from 1999 to 2013 with a minimum follow-up of 1year. Patient and testicular factors were related to diminished size. RESULTS: Sixty one patients, and 92 testicles were included...

BACKGROUND: We present the midterm results of the novel technique of two-stage laparoscopic traction orchiopexy (SLTO) for the high intraabdominal testis (IAT) for elongation of the testicular vessels without division. PATIENTS AND METHODS: Boys with IAT proven by laparoscopy were selected for the technique between September 2009 and April 2013 in 2 Egyptian pediatric surgery units. Boys <6months or >9years were excluded. The technique entails fixation of the testis to a point one inch above and medial to the contralateral anterior superior iliac spine for 12weeks...

INTRODUCTION: Classically, surgical approach for palpable undescended testis (pUDT) consists is an inguinal orchidopexy. In fact, a double incision allows an adequate mobilization of the spermatic cord and an easy dissection of a patent processus vaginalis and also to perform a subdartos pouch. For reduce potential mobility of the inguinal approach, in 1989 Bianchi and Squire proposed a transcrotal orchidopexy, using a high scrotal incision. We report our experiences and retrospectively evaluate the feasibility and postoperative success of the transcrotal approach for treatment of pUDT...

BACKGROUND: Maternal gestational smoking, diabetes, alcohol drinking, and pre-pregnancy obesity are thought to increase the risk of cryptorchidism in newborn males, but the evidence is inconsistent. METHOD: We conducted a systematic review and meta-analysis of studies on the association between maternal gestational smoking, diabetes, alcohol drinking, and pre-pregnancy obesity and the risk of cryptorchidism. Articles were retrieved by searching PubMed and ScienceDirect, and the meta-analysis was conducted using Stata/SE 12...

PURPOSE: Cryptorchidism is one of the most common pediatric disorders of the male endocrine glands and the most common genital disorder identified at birth. This guideline is intended to provide physicians and non-physician providers (primary care and specialists) with a consensus of principles and treatment plans for the management of cryptorchidism (typically isolated non-syndromic). MATERIALS AND METHODS: A systematic review and meta-analysis of the published literature was conducted using controlled vocabulary supplemented with key words relating to the relevant concepts of cryptorchidism...

Cryptorchidism represents the most common endocrine disease in boys, with infertility more frequently observed in bilateral forms. It is also known that undescended testes, if untreated, lead to an increased risk of testicular tumors, usually seminomas, arising from mutant germ cells. In normal testes, germ cell development is an active process starting in the first months of life when the neonatal gonocytes transform into adult dark (AD) spermatogonia. These cells are now thought to be the stem cells useful to support spermatogenesis...

BACKGROUND/PURPOSE: A normal testis in the scrotum is the most important outcome of the attempted pediatric orchidopexy for a true undescended testis. The reports of post-orchidopexy testicular atrophy in the literature have ranged from non-existent to unclear. Our purpose in this study was to estimate the incidence of and associated risk factors for post-orchidopexy testicular atrophy. METHODS: We performed a retrospective review of data from children who had an attempted orchidopexy for a true undescended testis from 1969 to 2003 inclusive...

BACKGROUND/AIM: Cryptorchidism affects 2-4% of newborn boys. Testicular descent requires the gubernaculum to differentiate into cremaster muscle (CM) during androgen-mediated inguino-scrotal descent, but the cellular mechanisms regulating this remodeling remain elusive. β-Catenin, a marker of canonical Wnt signaling, promotes myogenic genes and cellular adhesion. We aimed to determine if androgen receptor (AR) blockade altered β-catenin and its downstream myogenic proteins within the CM...
