Triorchidism: two case reports.

In this study, two cases of triorchidism are reported. The first case (29 years) had two right discrete ovoid nontender, firm, mobile lumps with testicular sensation. The second case (32 years) had two left discrete ovoid nontender, firm, mobile lumps with normal testicular sensation. They were subjected to the estimation of serum follicle-stimulating hormone, luteinising hormone, free and total testosterone, alpha-fetoprotein, prostate-specific antigen, karyotyping and semen analysis. Imaging included ultrasonography, transrectal ultrasound, magnetic resonance imaging and intravenous pyelography. The first case had two testes in the right side. Each one had an epididymis where one vas deferens was palpated. The second case had two left testes with normal testicular sensation. The lower left lump represented normal-sized testis attached to its epididymis and a single palpated vas deferens. Diagnosis of the first case was triorchidism associated with left varicocele (grade I) with oligoasthenoteratozoospermic semen profile. Intracytoplasmic sperm injection was carried out resulting in a twin. Diagnosis of the second case was triorchidism with accessory testis on the left side associated with left varicocele (grade I) and asthenozoospermic semen profile that was submitted to medical treatment. It is concluded that triorchidism is an uncommon congenital anomaly that should be not overlooked in diagnosing scrotal masses.

Urinary neutrophil gelatinase-associated lipocalin as a marker of severe lupus nephritis in children.

INTRODUCTION: More than 60% of children with systemic lupus erythematosus (SLE) develop lupus nephritis (LN). Neutrophil gelatinase-associated lipocalin (NGAL) is a protein secreted by leukocytes during inflammation and is overexpressed in the kidneys following ischemic and nephrotoxic damage. AIM: To study urinary and serum NGAL in children with SLE and investigate their possible role as markers of renal involvement. Methods Urinary and serum levels of NGAL were assessed in 33 children with active SLE (22 with and 11 without LN) and compared to 15 matched controls. RESULTS: Children with SLE had elevated urinary NGAL as compared to controls (P<0.001). Levels of urinary NGAL were higher in patients with LN than those without LN (P<0.001). In patients with LN, serum levels of NGAL were not significantly different from controls (P=0.4) and urinary NGAL correlated with the renal score of the Systemic Lupus Erythematosus Disease Activity Index (r=0.5, P=0.02) but not with serum NGAL (P=0.5). Urinary NGAL was significantly predictive of class III and IV LN (P=0.005) with 91% sensitivity and 70% specificity to levels ≥ 10.07 ng/mg creatinine. Conclusions Urinary NGAL is a sensitive marker of proliferative nephritis in juvenile SLE.

Transrectal ultrasound in patients with hematospermia.

INTRODUCTION: To illustrate the lesions detected with transrectal ultrasound (TRUS) in patients with hematospermia. MATERIAL AND METHODS: This study included 74 male patients (25-73 years old) affected by hematospermia. Clinical history was obtained and all patients underwent rectal examination as well as TRUS examination in both axial and coronal planes to evaluate the prostate, ejaculatory ducts and seminal vesicles. Biopsy was performed in 10 patients. RESULTS: Abnormalities were detected in 59 patients. Calculi (n = 20) were seen within the prostate, seminal vesicles and along the course of the ejaculatory ducts. Chronic prostatitis (n = 14) appeared as hyperechoic and hypoechoic areas within the prostate with capsule thickening suggesting seminal vesiculitis (n = 8). Granulomatous prostatitis (n = 3) appeared as hyperechoic and calcified areas scattered within the prostate and the seminal vesicles. Hypoechoic focal lesions and heterogeneous texture were seen in prostate cancer (n = 5). Utricular cysts (n = 3) appeared as small midline lesions, and Mullerian duct cysts (n = 8) appeared as larger midline cysts protruding above the prostate. Ejaculatory duct cysts (n = 4) appeared as thick walled cystic lesions along the course of the ejaculatory duct. Seminal vesicle cysts were detected in 2 patients. CONCLUSION: Our conclusion is that TRUS is a safe, non-invasive technique which can be used to detect lesions of the prostate, seminal vesicles and the ejaculatory ducts in patients with hematospermia.
