[A case of mesothelial cyst at the inguinal region].

A 54-year-old man presented with the left inguinal swelling. The operation was performed with diagnosis of the hydrocele of spermatic cord. A tumor was 3.

Varicocele complicating spontaneous arteriovenous fistula.

We describe herein a rare case of a varicocele complicating spontaneous arteriovenous fistula. A 40-year-old man was referred to our hospital in November 2006, complaining of a non-tender mass in the left scrotum at the age of 15 and thereafter. On examination, his left scrotum revealed a large varicocele, but no manifest superficial thrill was noted.

[Late relapse and urothelial carcinoma of residual ureter 16 years after radical nephrectomy: a case report].

A 66-year-old male was referred to our hospital for evaluation of tumors in his left residual ureter and the lung. He had a history of left nephrectomy due to "malignant renal tumor", performed by a general surgeon at another hospital 16 years ago. Since a definitive diagnosis of the kidney was uncertain, we speculated that the original renal disease was a renal pelvic cancer and had metastasized in the residual ureter and the lung.

[Arthritis following intravesical instillation of BCG for urothelial cancers].

Background: Intravesical instillation of bacillus Calmette-Guerin (BCG) is efficient for prophylaxis of superficial bladder cancer and treatment for carcinoma in situ (CIS) of the upper urethelial cancer. However, the incidence of adverse effects is relatively high, and those include reactive arthritis. We retrospectively evaluated the incidence and the outcome of reactive arthritis following intravesical BCG therapy for urothelial cancers.

[Experience with the memotherm stent in high-risk urinary retention patients].

Purpose: We report on our experience with the Memotherm stent implanted in high-risk patients who had an indwelling catheter.

Patients And Methods: Seventeen patients (mean age 80.6 years, range 55 to 93) who had an indwelling catheter were treated by placement of the Memotherm stent.

[The clinicopathological characteristics in renal cell carcinoma with end-stage renal disease].

Objectives: The influence and the interdependence of pathological and clinical factors on prognostic differences between renal cell carcinoma (RCC) with end-stage renal disease (ESRD) and RCC without ESRD after nephrectomy has remained unclear. We compare the clinicopathological features between RCC with and without ESRD.

Materials And Methods: From June 1993 to May 2000, 150 RCC patients who underwent nephrectomy were pathologically defined to have pT1 to pT3NXM0.

[Prognostic value of serum immunosuppressive acidic protein in renal cell carcinoma].

Background: To determine whether the immunosuppressive acidic protein (IAP) could be a useful marker for renal cell carcinoma (RCC), serum IAP levels were compared with clinicopathological features in RCC patients. Furthermore, IAP cutoff level to predict the recurrence was determined using receiver operating characteristics (ROC) curve analysis.

Patients And Methods: Between January 1994 and December 1998, pretreatment serum IAP was measured in 123 consecutive patients with PCC at Kitasato University Hospital.

Clinical significance of p53, mdm2, and bcl-2 proteins in renal cell carcinoma.

Objectives: To improve our understanding of the clinical relevance of p53, mdm2, and bcl-2 protein overexpression in renal cell carcinoma, we retrospectively investigated the immunohistochemical expression of p53, murine double minute 2 (mdm2), and bcl-2 and the relationship of this expression to clinicopathologic characteristics. p53 regulates the transcription of downstream effectors such as the oncoprotein mdm2, and bcl-2 has been shown to inhibit apoptosis triggered by wild-type p53.

Methods: The expression of p53, mdm2, and bcl-2 protein was studied by immunohistochemical methods in paraffin-embedded nephrectomy specimens from 112 patients whose clinicopathologic data confirmed renal cell carcinoma.

Transrectal high-intensity focused ultrasound for treatment of patients with stage T1b-2n0m0 localized prostate cancer: a preliminary report.

Objectives: To present our preliminary clinical results of transrectal high-intensity focused ultrasound (HIFU) in Stage T1b-2N0M0 prostate cancer. Efforts are being made to provide minimally invasive alternative treatment options with equal efficacy and fewer side effects. HIFU delivers ultrasound energy with rapid thermal necrosis of tissue in the focal region without damaging the surrounding tissue.

[Management of enterovesical fistula in patients with Crohn's disease].

Purpose: Enterovesical fistula in patients with Crohn's disease is intractable. Although there are some reports that the enterovesical fistula were successfully treated conservatively, closure of the fistula cannot always be achieved and surgical intervention may required for those patients. Since surgical closure of entero-entero fistula has a high risk of relapse, the strategy for treating enterovesical fistula has not been established.
