OBJECTIVES: To assess the implementation of the current guideline and identify potential underlying causes for late surgery in children with Undescended testis (UDT) in Germany. UDT is the most common surgical issue in paediatric urology. To avoid malignant degeneration and subfertility current guidelines recommend orchidopexy during the first year of life. However, this seems not to be implemented in practice. PATIENTS AND METHODS: 5547 patients with cryptorchidism at 16 hospitals nationwide were studied regarding age at orchidopexy between 2003 and 2016...

BACKGROUND: In congenital undescended testis (UDT) in humans, thermal insult damages early germ cell development during mini-puberty (3-6months) causing increased risk of both cancer and infertility. In rodents however, UDT causes infertility but not cancer. In the TS rat with congenital UDT we hypothesized that early germ cell development would be normal as UDT only becomes manifest at 3-4weeks (and the germ cells only become sensitive to thermal injury) after minipuberty is complete at 1week...

RATIONALE: Ectopic immature renal tissue (EIRT) is extremely rare in congenital malformations. Moreover, the fundamental pathogenesis of EIRT is still unclear and controversial. PATIENT CONCERNS: The right scrotum of a 1-year-old man was found empty for a period of 1 month. B-ultrasonography revealed normal bilateral kidneys and a hypoechoic nodule in the right groin. DIAGNOSES: Based on B-ultrasonography, surgery and pathological examination, we concluded a case of abnormally located and EIRT in the inguinal canal...

We aimed to determine the difference in tissue stiffness, which might reflect histologic damage, by comparing the potential of the shear wave elastography (SWE) values of operated undescended testes (OUT) with those of undescended testes (UT) and normal testes. A total of 120 patients (235 testes) were enrolled in the current study. Quantitative SWE values were measured by manually drawing contours of the entire testis structure with a free region of interest. A group of 66 OUT were classified as group A. Operation age and the period passed over the operation time and SWE values were compared among the testes assigned to group A...

BACKGROUND: Hepatocellular Carcinoma (HCC) is the most common primary carcinoma of the liver, which mainly metastasizes through the portal vein system. CASE PRESENTATION: Here, we report an extremely rare case in which HCC metastasized to the capsule of an undescended testis in the right inguinal area of the patient. A tumor approximately 8.8 × 7.0 cm in size was found in the patient's liver during a health check-up. Initially, it was considered a metastatic tumor because the patient was found to have cryptorchidism, which had been left untreated before he presented to our hospital...

PURPOSE: Superb micro-vascular imaging (SMI) is a new blood flow (BF) technique recently developed to outface the limitations of conventional Doppler imaging techniques (CDIT). SMI can observe micro-vascular BF and low-velocity BF. SMI is available in two modes as color SMI (cSMI) and monochrome SMI (mSMI). To evaluate testicular BF, we have compared color Doppler (CD), power Doppler (PD), cSMI, and mSMI techniques. PATIENTS AND METHODS: A total of 156 patients (310 testes) were included in the study...

Infertility occurs in up to 54% of men with bilateral undescended testes. Orchiectomy is considered the best therapeutic approach, especially when cryptorchidism is diagnosed in adulthood, due to a high risk of malignancy. A 33-year-old man was referred with a clinical presentation of empty scrotum and an ultrasonography and magnetic resonance imaging evaluation of intra-abdominal bilateral cryptorchidism. Follicle-stimulating hormone was 23.20 IU/L, luteinising hormone was 14.10 IU/L, total testosterone was 12...

Background: Many primary care physicians order an ultrasound (US) before referral to specialist care for suspected undescended testis; however, the value of this practice is questionable. Objective: To determine the proportion of boys referred for suspected undescended testis who had accompanying US, the cost of this practice and the accuracy of US for testis localization when compared with physical examination by a pediatric urologist. Methods: This was a retrospective chart review at a pediatric urology service, including all patients referred for suspected undescended testis from 2008 to 2012...

This study reports the experience of our tertiary referral center and proposes a new indicator, the growth percentage ratio (GPR), for determining the optimal timing of surgical intervention. A retrospective review of boys who underwent orchiopexy for undescended testis from 2001 to 2013 was conducted. We analyzed testicular volumes in different age groups using the UDT to normally descended testis ratio and testicular GPR. A total of 134 boys with unilateral undescended testicle underwent regular ultrasonography follow-up examinations for more than a mean of 3...

OBJECTIVES: To investigate the impact of preoperative ultrasonography (US) for detecting a viable testis in patients with a unilateral nonpalpable testis. METHODS: Patients with a unilateral nonpalpable testis or unilateral palpable undescended testis who underwent preoperative US were enrolled. Patients were divided into 3 groups as follows: nonpalpable testis/no testis (n = 27), which included patients who had a unilateral nonpalpable testis with no viable testis detected at surgery; nonpalpable testis/viable testis (n = 10), which included patients who had a unilateral nonpalpable testis with a viable testis identified at surgery; and palpable undescended testis (n = 63), which included patients who had a unilateral palpable undescended testis...

INTRODUCTION: An interparietal inguinal hernia is a rare form of hernia. In this type of hernia, the sac passes between the layers of the abdominal wall of the inguinal canal area. Although its treatment is very simple but pre-operative diagnosis is really a challenging issue. PRESENTATION OF CASE: A 62 years old male patient presented with complaint of a large swelling over right lower abdomen with absence of right testes since birth. The lump was measured 26×22cm in size...

Supernumerary testis, also known as polyorchidism, is a condition characterized by the presence of more than two testes. Another condition of the testes is seminoma, a common cause of testicular germ cell tumor. A 35-year-old male was transferred to our hospital with a diagnosis of abdominal mass causing abdominal pain. On physical exam, he had a palpable undescended left testicle in the left inguinal canal, which was determined to be seminoma. The mass was surgically removed, and the patient underwent chemotherapy...

INTRODUCTION: In up to 20% of patients presenting with undescended testes, one or both are non-palpable. Whereas the most reliable means to exclude an abdominal testis is laparoscopy, there has been a lot of debate about the role of inguinal ultrasound (US) in detecting non-palpable inguinal testis. While we do not aim to add another paper claiming the benefits of US, we wanted to determine the excess capability of US to determine the correct surgical approach - inguinal or laparoscopy...

AIMS: To evaluate the differences and changes of testicular volume and elasticity in normal (NL) testes and undescended testes (UDTs) of children using shear wave elastography (SWE). MATERIALS AND METHODS: Testicular ultrasound images from children younger than 60 months old were retrospectively reviewed. Testicular volumes and elasticities were compared between the UDT group and NL group. In patients with unilateral UDT (uUDT), we also compared the values between uUDT and contralateral grossly normal (CGN) testis groups...

Small bowel obstruction (SBO) is a common complication after abdominal surgery, and can occur due to many reasons. However, cryptorchidism can cause SBO in patients with no history of abdominal surgery. We report the case of a 67-year-old man with SBO caused by adhesions between an undescended testis and the terminal ileum.

REVIEW
John M Hutson, Jaya Vikraman, Ruili Li, Joergen Thorup
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...
