[The results of a long-term follow-up for patients with stage Ta bladder cancer, especially regarding those with multiple recurrences].

Objective: We reviewed our series of stage Ta bladder cancer patients with a long-term follow-up in order to clarify the prognosis of these patients, especially those who have repeated recurrences.

Materials And Methods: A retrospective study was done on 88 patients with stage Ta bladder cancer who were treated between 1971 and 1990 at our hospital. All patients reviewed were followed up for at least 5 years.

[Relationship between grade and stage of renal pelvic and/or ureteral tumor and associated bladder tumor].

Objective: The purpose of this study was to analyze bladder tumor (BT) associated with renal pelvic and/or ureteral tumor (RUT), with emphasis on the relationship between the grade and stage of these tumors.

Methods: We reviewed 77 cases of RUT operated upon at our hospital during the last 14 years. We herein define stage T1b tumor as invasive since this stage of tumor is considered to have a different biologic behavior and potential compared to stage Ta tumor.

Testicular cancer in father and son.

The occurrence of testicular tumors in closely related family members is rare. We report a case of testicular cancers in a father and son. The father had pure seminoma, and his son developed a mixed nonseminomatous germ cell tumor.

[Experience with incontinent urinary diversion--review of 31 ureterocutaneostomies, 101 ileal conduits and 107 colonic conduits].

During the past 20 years, 31 ureterocutaneostomies (UC), 101 ileal conduits (IC) and 107 colonic conduits (CC) were performed. In the UC group, most of the patients were aged or had unresectable invasive pelvic malignancies. The operative mortality was 6.

[Prolonged exposure to intravesical foreign body induces a giant calculus with attendant renal dysfunction].

A 31-year-old man came to our hospital complaining of severe voiding pain. He had inserted a fishing line made of nylon into his urethra at the age of eighteen, which was unable to be taken out and had been left there for 13 years. Preoperative ultrasonogram showed severe bilateral hydronephrosis and the serum BUN and creatinine level were as high as 45.

[The results of long-term bladder cancer patient follow-up. The role of TUR in stage T1b and T2 bladder cancers].

We evaluated transurethral resection of bladder tumor (TUR) for stage T1b & T2 bladder cancers by reviewing our long-term results from 181 patients. All were followed for a minimum of 5 years or until death. In 29 patients with a stage T1b tumor treated by TUR, the 5- & 10-year survival rates were 82.

[Clinical study of sparfloxacin, a new quinolone derivative, on urinary tract infection].

Sparfloxacin (SPFX) was evaluated for its clinical efficacy in 22 patients with acute uncomplicated cystitis (AUC) and 51 with chronic complicated urinary tract infection (CC-UTI). SPFX was administered in a single oral daily dose of 100 mg for 3 days to the patients with AUC. According to the UTI criteria, the efficacy rate was 100% (excellent rate was 78.

[Clinical evaluation of vasopressin in the elimination of intestinal gas].

Vasopressin, a hormone secreted from the posterior lobe of the hypophysis, has endocrinological and antidiuretic effects; it contracts vessels and smooth muscles, especially intestinal smooth muscle. In the present study, we investigated the role of vasopressin (Pitressin: arginine-vasopressin) in elimination of intestinal gas on excretory urography reading. Sixty outpatients were randomly divided into six groups.

[Guideline of surgical treatment of prostatic adenocarcinoma].

Based on study of 274 cases of prostate cancer treated in our clinic, selection of patient for radical surgical treatment and choice of procedures were discussed. The radical surgical procedures experienced in our clinic were classified as 31 cases of radical prostatectomy, 4 cases of radical cystoprostatectomy and 7 cases of pelvic exenteration. The endocrine therapy was added to non curative cases postoperatively.

Efficacy and safety of Aztreonam, a monobactam antibiotic developed by E.R. Squibb & Sons, Inc.

[Clinical results and safety of ceftazidime, a new injectable cephalosporin, in long-term administration of the treatment of infections in urology].

CAZ was administered to 34 patients in the field of urology for treatment or prevention of serious infections with many complicated factors. The duration of treatment ranged from 9 to 30 days, the most frequent being 14 days, which was the duration originally set as the standard. As the results CAZ was considered to be one of the drugs of choice in the cases requiring long-term treatment, from the viewpoint of both efficacy and usefulness.

[A clinical study of renal tumors].

Seventy one patients with renal tumors treated at our clinic during the 11 years from 1970 to 1980 were clinically examined. The results are summarized as follows. The frequency of patients with renal tumors was 0.

[Clinical studies on long acting amoxicillin in the field of urology].

Long acting amoxicillin (L-AMPC) was studied in the treatment of 40 patients with urinary tract infections. The dosage administered was 1,000 mg/day (b.i.

A case of secondary aldosteronism induced by pheochromocytoma.

A case of secondary aldosteronism caused by a pheochromocytoma containing a large amount of norepinephrine is described. The increased level of angiotensin induced by norepinephrine seems to play an important role in the development of secondary aldosteronism.
