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...

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...

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...

INTRODUCTION: The timing of surgery in cryptorchidism has been debated for a long time. Reports on histology suggest better fertility outcomes with early surgery, whereas evidence of long-term improved fertility still lacks sound data. The aim of this study is to analyze sperm count and motility in a cohort of young men operated on during the first 2 years of life for cryptorchidism. PATIENTS AND METHODS: A total of 78 young men (age, 18-26 years) surgically treated for cryptorchidism in the second year of life were recalled to evaluate testicular volume and sperm count and motility...

The first half of this review examines the boundary between endocrinology and embryonic development, with the aim of highlighting the way hormones and signaling systems regulate the complex morphological changes to enable the intra-abdominal fetal testes to reach the scrotum. The genitoinguinal ligament, or gubernaculum, first enlarges to hold the testis near the groin, and then it develops limb-bud-like properties and migrates across the pubic region to reach the scrotum. Recent advances show key roles for insulin-like hormone 3 in the first step, with androgen and the genitofemoral nerve involved in the second step...
