[Follow-up method for patients with non-muscle-invasive bladder cancer who remained recurrence-free for a long time].

To determine the follow-up schedule in patients with non-muscle-invasive bladder cancer who had remained recurrence-free for 5 or more years, we retrospectively reviewed 258 patients with Ta and T1 bladder cancer who had been free of recurrence for at least 5 years. Of these 258 patients, subsequent recurrences developed in 100 patients. In spite of our recommendation that cystoscopic follow-up be done at 12-month intervals for patients who remained recurrence-free for more than 5 years, 45 had been followed at intervals of more than 12 months (range, 13-77 months) when the recurrences were found.

Isolated ACTH deficiency in self referred patients for LOH syndrome: two case reports.

We experienced two cases of isolated ACTH deficiency (IAD) in patients self referred for late-onset hypogonadism (LOH) syndrome. IAD is secondary adrenal insufficiency due to lack of secretion of ACTH and delayed diagnosis of this rare condition may be life-threatening. The predominant symptoms of IAD, such as general malaise and weakness, resemble those of LOH syndrome creating the possibility that IAD may be referred as LOH syndrome.

Silodosin and its potential for treating premature ejaculation: a preliminary report.

Premature ejaculation is a common sexual problem, as is erectile dysfunction. We evaluated silodosin, a highly selective α1A-adrenoceptor antagonist, as a new treatment option for premature ejaculation. α1-Adrenoceptor antagonists are widely used for lower urinary tract symptoms, and clinical studies on silodosin have shown excellent clinical efficacy for lower urinary tract symptoms.

[Primary testicular leiomyosarcoma].

[Isolated ACTH deficiency in a late onset case of hypogonadism (LOH) not diagnosed by examination in an internal medicine clinic].

We present a case of isolated adrenocorticotrophic hormone (ACTH) deficiency (IAD) in a late onset hypogonadism (LOH) clinic, not diagnosed by examinations in internal medicine. A 54-year-old man showed body weight loss with severe appetite loss, general malaise and hypotension. He visited our clinic for a checkup for LOH after general examinations in internal medicine.

Shock wave lithotripsy for renal stones is not associated with hypertension and diabetes mellitus.

Objectives: To clarify the influences of shock wave lithotripsy (SWL) treatments for renal and ureteropelvic junction stones on new onsets of hypertension and diabetes mellitus (DM).

Methods: We compared the new onsets of hypertension and DM after SWL in renal and ureteral stone groups. The renal stone group consisted of 772 patients treated with SWL, who had a possibility of renal and pancreatic shock wave damage.

[Clinical evaluation and antimicrobial susceptibilities of cases of gonococcal urethritis treated in our hospital].

We reviewed the results of clinical examinations conducted on and antimicrobial susceptibilities to Neisseria gonorrhoeae isolated from 51 patients with gonococcal urethritis who visited our hospital during the period from February 2005 to April 2006. The type of sexual activity by which the bacteria was transmitted was oral sex in 81.6% (40/49) of the patients, and none of the patients used a condom during oral sex.

Comparison of surgical outcome and the systemic inflammatory response syndrome score between retroperitoneoscopic hand-assisted nephroureterectomy and open nephroureterectomy.

The goal of this study is to compare surgical and oncological outcomes of laparoscopic nephroureterectomy and the open surgery using the concept of systemic inflammatory response syndrome (SIRS) in addition to common variables. Thirty-six and 23 patients having upper urinary tract urothelial cancer who were operated on with retroperitoneoscopic hand-assisted nephroureterectomy (RHANU) or standard open nephroureterectomy (ONU) retrospectively, were analyzed. Median operation time was 140 (range 70-200) and 60 (range 45-85) minutes, respectively in the RHANU group and the ONU group.
