We reviewed 272 patients with hypospadias who were treated surgically to survey the complicated anomalies in these patients. Urogenital anomalies were recognized in 40 per cent of the 272 cases and extra-urogenital anomalies were noted in 9.2 per cent. Undescended testis was the most frequently seen anomaly, having been noted in 13.2 per cent of the 272(More)
A 5-year-old boy with multiple minor anomalies and mental retardation was found to have chromosomal condition of 46,XY,inv dup(9p)(pter→p13::p21→p24::p13→qter). The clinical features of the propositus fit well with those of trisomy 9p which have been established to be a clinical entity.
Serum levels of luteinizing hormone and follicle-stimulating hormone before and after luteinizing hormone-releasing hormone stimulation, and levels of testosterone before and after 3 days of treatment with human chorionic gonadotropin were determined by radioimmunoassay in 98 boys with hypospadias (2 to 8 years old). The doses of luteinizing(More)
An enlarged prostatic utricle is often associated with hypospadias. To evaluate the relationship between the incidence of prostatic utricle and the degree of hypospadias, we performed retrograde urethrography and/or micturating cystourethrography on 280 patients with hypospadias. Prostatic utricles were demonstrated in 84 patients (27.5%) and the incidence(More)
BACKGROUND Tacrolimus (FK506) is currently used as the primary immunosuppressant in clinical kidney transplantation in some centers. The purpose of this study was to evaluate the pharmacokinetics of this drug and to see if trough level, which has been used widely in therapeutic drug monitoring, can be used as an appropriate substitute for other(More)
Of 485 patients with hypospadias who underwent urethrography, enlarged prostatic utricles were found in 173 (35.7%). Utricles with a higher grade of enlargement were seen mainly in patients with a severe degree of hypospadias. Serum testosterone levels before and after 3 days' treatment with human chorionic gonadotrophin were determined by radioimmunoassay(More)
A case of left adrenal hepatoid carcinoma is reported. The patient was a 57-year-old male and his chief complaint was general fatigue. Preoperative laboratory data showed markedly increased levels of alpha-fetoprotein (AFP) (30,500 ng/ml) and PIVKA-II (3.01 AU/ml). Both computed tomography (CT) and magnetic resonance computed tomography (MRCT) showed left(More)
