We, herein, present a male neonate with an antenatally detected intra-abdominal cyst who presented at 18 days of life at which time, the ultrasound revealed a 5×4 cm cyst. Since he was asymptomatic, we planned to repeat the ultrasound a month later and operate if the cyst showed no regression. However, a week later, he presented with an acute abdomen, irritable cry and a repeat ultrasound showing a larger (8×6 cm) cystic mass with debris within. He was taken up for an emergency laparotomy. Intraoperatively, the cyst was found arising from the left lateral abdominal wall free from all structures with a twisted pedicle...

OBJECTIVE: To clarify the prevalence and chronological changes of testicular microlithiasis in isolated congenital undescended testes, retrospective chart review was performed. METHODS: Among children with palpable isolated undescended testes who underwent orchiopexy at less than 3 years of age between January 2009 and May 2016, those who had preoperative testicular ultrasonography were enrolled. Testicular microlithiasis was classified as limited or classic. RESULTS: Sixty-five patients (54 unilateral undescended testes and 11 bilateral undescended testes) were enrolled...

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.

BACKGROUND: Inguinal hernia repair is one of the most frequently performed surgical procedures in infants and young children. Laparoscopic hernia repair in infancy and childhood is still debatable. There are many techniques available for laparoscopic hernia repair in pediatrics. The aim of the study is to compare laparoscopic intracorporeal purse-string suture ligation of the hernia defect leaving the sac intact versus disconnection of the hernia sac with intracorporeal suture of proximal part...

It has been known for many years that boys with unilateral or bilateral undescended testis (cryptorchidism) tend to have a low IQ, and those who belong to the high infertility risk (HIR) group perform less well at school than low infertility risk (LIR) patients. However, the molecular biological processes underlying this phenomenon are not understood. In this study, we report the outcome of testicular RNA profiling for genes involved in long-term memory formation. We analyzed the histology and the transcriptome of testicular biopsies from bilateral HIR cryptorchid boys, comparing those who received GnRHa treatment for 6 months after the first surgery with those who did not receive GnRHa before the second surgery...

INTRODUCTION: The traditional management paradigm for nonpalpable testis (NPT) has been that inguinal or scrotal exploration for a nubbin may be omitted when blind ending vessels are observed during diagnostic laparoscopy. Our aim was to examine whether blind ending vessels excluded the presence of a nubbin in a series of boys who underwent exploration in this setting. MATERIALS AND METHODS: Using a surgical database and chart review, pre-pubertal boys (≤12 years) with the diagnosis of undescended or atrophic testis who underwent a diagnostic laparoscopy for unilateral NPT between 2000 and 2015 were retrospectively identified...

Undescended testis - known as cryptorchidism - is one of the most common congenital abnormalities observed in boys, and is one of the few known risk factors for testicular cancer. The key factors that contribute to the occurrence of cryptorchidism remain elusive. Testicular descent is thought to occur during two hormonally-controlled phases in fetal development - between 8-15 weeks (the first phase of decent) and 25-35 weeks gestation (the second phase of descent); the failure of a testis to descend permanently is probably caused by disruptions to one or both of these phases, but the causes and mechanisms of such disruptions are still unclear...

The aim of this study was to compare sperm DNA damage between men with a history of congenital undescended testis (UDT) and men with a history of acquired UDT. A long-term follow-up study of men with previous UDT was performed. Fifty men with congenital UDT who had undergone orchiopexy at childhood age, 49 men with acquired UDT after a 'wait-and-see'-protocol (e.g. awaiting spontaneous descent until puberty and perform an orchiopexy in case of non-decent), and 22 healthy proven fertile men were included. The DNA fragmentation index (DFI) using sperm chromatin structure assay (SCSA) was used to express the level of sperm DNA damage...

Management of testicular rupture with a large tunical defect may not be feasible without excision of viable tissue. This study describes the use of a vascularized tunica vaginalis flap, without debridement of viable tissue, in four adolescents. Postoperative ultrasound showed good blood flow and 80% volume of the contralateral testis in two cases. Postoperative exam revealed normal exam and ultrasonographic appearance in three patients, the fourth was demonstrated to be small and undescended during evaluation of contralateral testicular torsion...

AIM: Undescended testis (UDT) affects 1-6% of males and is one of the most common disorders in paediatric surgery.Updated consensus guidelines now recommend surgical management of UDT by 18 months. We compare the age at referral and subsequent timing of orchiopexy with data published from 1996-1998 at our institution, prior to the advent of updated guidelines. METHODS: A retrospective review of all patients undergoing an orchiopexy for UDT from 2014 to 2016 was conducted...

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...

BACKGROUND: Prune Belly Syndrome (PBS) is a rare entity, usually found in male neonates. It comprises complex urinary tract anomalies, bilateral undescended testis and absence of anterior abdominal wall muscles. Patients with unilateral abdominal wall deficiency, unilateral undescended testis and female neonates with abdominal wall laxity are classified as Pseudo Prune Belly syndrome (PPBS). Reports on PPBS do not highlight the radiological and imaging characteristics of this syndrome and the current literature on the role of newer imaging modalities, such as Magnetic Resonance Imaging (MRI), remains relatively sparse...

Cystic dysplasia of the testis is a rare, benign pathologic finding. We present two recent cases of cystic dysplasia of the testis to our practice. The first case involves an 11 month old male presenting with a non-palpable, intra-abdominal left testis. The second case involves a 7 year old male with left scrotal swelling and a history of left renal agenesis. After review of the literature, the first case represents the first report of cystic dysplasia of the testis in an undescended, intra-abdominal testicle...

BACKGROUND: Polybrominated diphenyl ethers (PBDEs) are flame retardants found in North American household products during the past four decades. These chemicals leach out in dust as products age, exposing individuals daily through inhalation and ingestion. Animal studies suggest that PBDEs disrupt sex hormones and adversely affect development of the reproductive system. OBJECTIVES: In the present study, we examined whether there is a link between maternal hair PBDE concentrations and the risk of cryptorchidism (undescended testes) in male infants; testis descent is known to be dependent on androgens...

Inguinal hernia is a common disorder of childhood that requires surgical repair at diagnosis. Traditionally, it is operated upon by open inguinal incision. However, with the introduction of laparoscopic repair in 1990, opinion of scientific community is divided concerning the best method of pediatric herniotomy. Educated parents, who long to have the choicest of the best, often gather information from internet and prefer to discuss their concerns with primary care physicians. This descriptive review is intended to provide practicing pediatricians with updated evidence-based information which will enable them to counsel parents regarding the choice of hernia repair...

Cryptorchidism or undescended testis (UDT) is a common congenital abnormality associated with increased risk for developing male infertility and testicular cancer. This study elucidated the effects of endogenous ghrelin or growth hormone secretagogue receptor (GHSR) deletion on mouse reproductive performance and evaluated the ability of ghrelin to prevent testicular damage in a surgical cryptorchid mouse model. Reciprocal matings with heterozygous/homozygous ghrelin and GHSR knockout mice were performed. Litter size and germ cell apoptosis were recorded and testicular histological evaluations were performed...
