Aashish Rajesh, Mohammed Farooq
INTRODUCTION: Persistent Mullerian duct syndrome (PMDS) is a rare type of male pseudohermaphroditism. Transverse testicular ectopia (TTE) is characterized by one testis moving to the opposite side and both testes traversing the same inguinal canal. CASE PRESENTATION: An 11-month-old boy presented with bilateral cryptorchidism. The left testis was not palpable; the right testis was canalicular with a right inguinal hernia. Ultrasound showed both testes located in the right inguinal canal...

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...

Splenogonadal fusion (SGF) is a rare congenital malformation. Since it lacks characteristic features, very few cases of SGF have been diagnosed preoperatively. Laparoscopy was effective in both diagnosing and surgically treating this condition. Herein, we reported left side SGF in a male patient who was diagnosed during laparoscopic exploration, and Fowler-Stephens orchidopexy was implemented at the same time. The patient was followed up for one year. At a 6-month follow-up, the left scrotum demonstrated swelling and the internal contents were hard...

Testicular function is particularly susceptible to vascular insult, resulting in a negative impact on sperm production and quality of the ejaculate. A prompt diagnosis of testicular dysfunction enables implementation of appropriate treatment, hence improving fertility forecasts for stallions. The present research aims to: (1) assess if Doppler ultrasonography is a good tool to diagnose stallions with testicular dysfunction; (2) to study the relationship between Doppler parameters of the testicular artery and those of sperm quality assessed by flow cytometry and (3) to establish cut off values to differentiate fertile stallions from those with pathologies causing testicular dysfunction...

OBJECTIVE: This article discusses scrotal ultrasonic features of patients with a congenital bilateral absence of the vas deferens (CBAVD). METHODS: Thirty-six patients with CBAVD were examined to obtain image characteristics of the bilateral testicle and epididymis by ultrasound. Each patient received a pathological examination of the sperm by percutaneous epididymal biopsy. RESULTS: Scrotal ultrasonic features were as follows: (1) testicular volumes were normal in all the 36 patients; (2) 21% (15/72) of the heads of epididymis, 67% (48/72) of the heads and bodies of epididymis, and 12% (9/72) of the heads, bodies, and tails of epididymis could be shown in the 72 epididymides of the 36 patients; (3) cystic or tubular dilation of the epididymis was obvious in all 72 abnormal epididymides; and (4) bilateral vas deferens could not be found in these patients...

RATIONALE: Lipoid congenital adrenal hyperplasia (LCAH) is extremely rare, but is the most fatal form of congenital adrenal hyperplasia resulting from mutations in the steroidogenic acute regulatory protein (STAR) gene. LCAH arises from severe defects in the conversion of cholesterol to pregnenolone, the precursor of all steroids. PATIENT CONCERNS: A case was reported that an 11-month-old Chinese girl who presented with a sex development disorder and hyponatremia...

INTRODUCTION: Testicular torsion threatens testicular viability with increased risk of loss with delayed management. Still, healthy adolescents continue to be transferred from community hospitals to tertiary hospitals for surgical management for torsion even though adult urologists may be available. We sought to determine reasons behind patient transfer and to evaluate whether transfer to tertiary centers for testicular torsion leads to increased rates of testicular loss. MATERIALS AND METHODS: A retrospective chart review was performed for patients presenting to our free-standing pediatric tertiary care facility with surgically confirmed testicular torsion during the 5-year period between January 2011 and January 2016...

An inguinal hernia occurs when an intestinal loop or part of the omentum or genital organs passes into the scrotal cavity or labia through an incompletely obliterated processus vaginalis. Inguinal hernias are most common in preterm neonates, especially at 32-weeks gestation. Content of hernia is mostly bowel and ovary/testicles. Presence of uterus in herniated sac is rare, and only few cases are reported in literature. Hernia is more frequently located on the right side because the right processus vaginalis closes later than the left...

BACKGROUND: Segmental testicular infarction is a very rare condition, which can mimic a testicular torsion or testicular cancer. Correct diagnosis is difficult but it is important to avoid unnecessary radical treatment. CASE PRESENTATION: We report a clinical case of a 36-year-old white man who presented at our emergency department with subacute testicular pain. A urine analysis, Doppler ultrasound, surgical exploration, blood analysis, and magnetic resonance imaging were performed to diagnose his condition, to exclude a testicular torsion, and to raise confidence in its non-malignancy...

Our objective was to assess the differential diagnostic value of classification of obstructive versus nonobstructive azoospermia by scrotal ultrasound. Forty patients with azoospermia were selected for our study (ages, 23-35; average, 29 ± 5.34 years). Patients were divided into the obstructive (17) or nonobstructive (23) azoospermia category. Twenty "healthy" volunteers were selected for the control group. We observed the testis, epididymis, and vas deferens in all subjects. Testicular volumes were calculated and compared with the control group for both obstructive and nonobstructive groups...

Acute scrotum is one of the most common urologic emergencies in children and adolescents. This condition involves acute testicular pain, which is often accompanied by scrotal swelling and erythema. It is most important to distinguish between cases that require immediate surgery and those that can be treated conservatively. As patient history and physical findings may not always be unequivocal, ultrasound with Colour-Coded Doppler Sonography is the imaging modality of choice for further evaluation. Testicular torsion and other differential diagnoses such as epididymitis, appendiceal torsion, intratesticular haematoma after trauma, or complicated inguinal hernia have to be considered...

Granulomatous Orchitis secondary to lymphatic filiarisis is a rare diagnosis within the United States. We report a case of a 22yo Male from Sri Lanka, with a new onset scrotal swelling and palpable right testicular mass. Ultrasound identified a 1 cm right testicular mass with signs of tunica albuginea invasion. A right inguinal radical orchiectomy was performed and pathology showed Filarial orchitis. This report describes the detailed history, physical exam, and diagnostic workup and treatment options for a rare entity for acute scrotal pathology...

OBJECTIVES: To assess the long-term evolution of the testicles preserved after testicular torsion (TT). MATERIAL AND METHODS: We realized a prospective study by ultrasound of patients diagnosed TT that underwent orchidopexy. We reviewed 85 patients treated for acute scrotum (2004-2014), finding 49TT. We excluded from the study 15 perinatal torsions, 14 orchiectomies and 5 patients who refused to participate. We analyzed 15 patients, comparing testicular volumes between affected and contralateral testes, and the difference in volume between the two testes of the 15 cases with 14 control patients (Mann-Whitney U test)...
