[Metastatic renal tumor originating from esophageal carcinoma: a case report].

A 46-year-old woman with a past history of esophageal carcinoma was hospitalized with the chief complaint of right abdominal pain. Enhanced computed tomography (CT) and selective renal angiography suggested a metastatic renal tumor. Right nephrectomy was performed. Histological examination revealed a renal tumor originated from esophageal squamous cell carcinoma. Metastatic renal tumors are frequently observed at autopsy, but clinically they are extremely uncommon. Thirty-four clinical cases of metastatic renal tumors reported in the Japanese literature during these 20 years are discussed including the present case.

[Clinical statistics on outpatients, inpatients and operations in 1986].

Statistical studies were made on 1,637 outpatients, 568 inpatients and 563 operative procedures at our department in 1986. The most frequent diseases among the outpatients were urogenital infections followed by anomalies, tumors and stones. The major diseases among the inpatients were hypospadias, vesicoureteral reflux, benign prostatic hypertrophy, bladder tumor and congenital urethral stenosis. A total of 563 operations were performed. The five major operations were hypospadia repair, optic internal urethrotomy, transurethral resection of prostate, ureterocystoneostomy and percutaneous nephrolithotripsy.

[XYY syndrome: report of three cases].

Three cases of XYY syndrome (YY syndrome) were experienced. Two cases had such rare associated anomalies as hypospadias and cryptorchism. Pathogenesis, incidence, clinical symptoms, gonadal function and fertility of the patients with XYY syndrome are briefly discussed.

[Clinical evaluation of long-term administration of terodiline hydrochloride for the treatment of patients with pollakisuria and incontinence].

We evaluated the effectiveness and side effects of long-term administration of terodiline hydrochloride in patients with chief complaints of pollakisuria or incontinence or both due to unstable bladder or neurogenic bladder associated with uninhibited contraction. The dose was 24 mg once daily. The symptoms such as pollakisuria and incontinence improved in 31 out of 41 patients (76%). Mild side effects were observed in 12 out of 47 patients (26%), which were thirst, dizziness, dysuria, urticaria and gastrointestinal symptoms. An increasing tendency of both maximum desire to void and compliance (p less than 0.10), and significant difference in maximum static pressure (p less than 0.05) were observed on urodynamic examinations before and after administration of this medicine. The results obtained from this study suggest that terodiline hydrochloride may be greatly recommended for patients with such symptoms as pollakisuria and incontinence.

[Studies on the half-life of C-terminal parathyroid hormone in chronic renal failure].

Subtotal parathyroidectomy (PTX) was performed for patients with hyperparathyroidism associated with chronic renal failure, and from sequential determination of PTH after PTX, the half-life of 2 different C-PTH was calculated. The half-life (T 1/2) of 46 approximately 84 PTH and 65 approximately 84 PTH was 18.1 +/- 3.9 and 14.0 +/- 2.2 hours (Mean +/- SD) respectively. Half-life of both C-PTH was markedly prolonged compared with that (30 approximately 60 minutes) of healthy subjects. It is considered that the longer half-life of 46 approximately 84 PTH than 65 approximately 84 PTH might be attributed to the difference of molecular weight, degrading enzymes and operative procedures. Determined value of C-PTH in chronic renal failure should be evaluated in consideration of prolonged metabolic clearance of C-PTH.

[A case of Skene's duct cyst].

We experienced a case of paraurethral cyst in a 40-year-old woman. The cyst was thought to have derived from left Skene's duct and marsupialized. Twenty nine cases with paraurethral cyst in the Japanese literature are also reviewed.

[Clinical statistics on outpatients, inpatients and operations in 1985].

Statistical studies were made on 1,795 outpatients, 528 inpatients and 518 operative procedures at our department in 1985. The most frequent diseases among the outpatients were urogenital infections followed by anomalies, stones and tumors. The major diseases among the inpatients were hypospadias, vesicoureteral reflux, congenital urethral stenosis, bladder tumor and benign prostatic hypertrophy. A total of 518 operations were performed. The five major operations were optic internal urethrotomy, hypospadias repair, ureterocystoneostomy, and transurethral resection of prostate and of bladder tumors.

Surgical correction of incomplete penoscrotal transposition associated with hypospadias.

A surgical technique for correction of incomplete penoscrotal transposition associated with hypospadias is presented. An inverted omega skin incision is made around the scrotal skin, and the base of the penis and scrotal flaps are brought beneath the penis. The operation is performed after the completion of hypospadiac repair. This technique was applied to 20 cases and cosmetic results were satisfactory.

Gonadotropin and testosterone response in prepubertal boys with hypospadias.

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 hormone-releasing hormone and human chorionic gonadotropin were calculated for body surface. The basal and peak levels of serum luteinizing hormone, follicle-stimulating hormone and testosterone in patients with hypospadias were compared with 9 endocrinologically normal boys of the same age without hypospadias. Luteinizing hormone response to luteinizing hormone-releasing hormone stimulation was significantly impaired in boys with hypospadias and also simple hypospadias (no associated anomaly). Basal levels of luteinizing hormone in boys with simple hypospadias and levels of follicle-stimulating hormone in patients with hypospadias were significantly low. The maximum testosterone response to human chorionic gonadotropin stimulation was significantly decreased in boys with severe hypospadias in direct proportion to the degree of hypospadias.

Surgical treatment for enlarged prostatic utricle and vagina masculina in patients with hypospadias.

Fourteen patients with hypospadias were treated surgically for either an enlarged prostatic utricle (6) or vagina masculina (8). Six vaginae masculinae were removed by an extravesical abdominal approach. One enlarged prostatic utricle was removed by the perineal approach. Three enlarged utricles were removed by an abdominoperineal approach. The transtrigonal approach was recently used for three enlarged utricles and one vagina masculina in four patients. Surgical results in these 14 patients were satisfactory. One post-operative complication of transient mild bilateral vesicoureteric reflux was seen after a transtrigonal removal of an enlarged utricle. Potency was not affected in any approaches in four patients who were older than 12 years. The transtrigonal approach was found to be the best for good exposure of the lesion.
