[A case of recurrent renal cell carcinoma which recurred after fourth surgical resection and survived for about 2 years by medroxyporgesterone acetate administration].

A 62-year-old man visited our hospital complaining of asymptomatic gross hematuria. Right radical Computed tomography (CT) demonstrated an 8 cm mass in the right kidney. nephrectomy was done in March 1995, and the pathological examination revealed renal cell carcinoma (RCC), clear cell type, G2>G1.

Cardiac metastasis of renal pelvic cancer.

A 66-year-old man was referred to our hospital with chest discomfort and shortness of breath. Seven months previously he had undergone a laparoscopic left nephroureterectomy for a left renal pelvic tumor and was given two cycles of adjuvant chemotherapy (methotrexate, epirubicin and cisplatin). Echocardiogram showed an 8-mm sized mass extending from the right atrium into the right ventricle.

[Prostate cancer development after transurethral resection of the prostate--histopathological studies of radical prostatectomy specimens].

Purpose: We investigated prostate cancer (ca.) development after transurethral resection of the prostate (TURP).

Patients And Methods: From 1995 to 2003, 430 patients (pts.

[Propiverine hydrochloride improved correlatively subjective QOL and objective findings in Japanese patients with urinary frequency and/or incontinence].

To investigate how urinary frequency and incontinence affect the patient's subjective quality of life (QOL) and whether an improvement in objective findings by medical treatment affects his/her subjective QOL, a voiding diary using the King's Health Questionnaire (KHQ) and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) was delivered to patients with urinary frequency and/or incontinence before and after treatment with propiverine hydrochloride for 8 weeks. Sixty-eight patients completed the diary and the questionnaires. Objective symptoms decreased significantly with respect to the mean frequency of urination and to the mean incidence of urinary incontinence.

[Small cell carcinoma of the bladder: a case report].

A 61-year-old man was referred to our hospital with a complaint of gross hematuria and lower abdominal discomfort. Ultrasonography, magnetic resonance imaging and cystoscopy revealed a nodular invasive tumor in urinary bladder. The histopathological findings of transurethral-biopsy specimen was the small cell carcinoma and transitional cell carcinoma of the bladder infiltrating into smooth muscle layer.

[Giant seminoma in abdominal retention of the testis manifested with unilateral leg pain: a case report].

A 26-year-old man was admitted to the department of surgery of our hospital with a complaint of intermittent left leg pain for the past two weeks. Ultrasonography revealed reduced blood flow to the tibial artery, which suggested a vascular disease like arteriosclerosis obliterans. Enhanced computed tomography (CT) revealed a huge abdominal tumor and a 3-dimensional CT scan showed a feeding artery from the left renal artery to the huge tumor.

[Vesicovaginal fistula associated with a vaginal foreign body: a case report].

A 14-year-old girl was referred to our hospital with severe pyuria pointed out in a school health check up. An intravenous pyelography and a cystography revealed a foreign body in the pelvic region outside the bladder and pooling of contrast medium in the vagina. Conputed tomography confirmed the foreign body in the vagina.

[Treatment with TAE of subcapsular hematoma as a complication of extracorporeal shock wave lithotripsy (ESWL): a case report].

A 58-year-old man with a left renal stone and with poor controlled hypertension was attacked by sudden onset of left renal colic pain, gross hematuria and nausea at 3 hours after ESWL. Ultrasonography and enhanced computed tomography revealed severe subcapsular hematoma, which compressed the left kidney. Since serum hemoglobin level continued to decrease in spite of 7 days of conservative therapy, we performed transfusion of red blood cells and selective transarterial embolization (TAE).

[Usefulness of extension of disease as a prognostic factor in relapsed prostate cancer patients of stage D].

Objective: The prognosis of prostate cancer has been evaluated by clinical stage or pathological grade. PSA parameters including PSA density and PSA doubling time have not always precisely reflected the prognosis of prostate cancer. The aim of this study was to evaluate PSA parameters and extension of disease (EOD) grade as prognostic factors for relapsed prostate cancer.

[Two cases of retroperitoneal liposarcoma arisen from perirenal fat tissue, which could not be diagnosed preoperatively].

We report two cases of retroperitoneal liposarcoma arisen from the perirenal fat tissue, which could not be diagnosed preoperatively. Case 1 is a 58-year-old male. He complained of left flank tumor.

[Spontaneous rupture of the ureter caused by metastatic ureteric tumor: a case report].

A 66-year-old man was admitted to our hospital with left flank pain. Drip infusion pyelography (DIP) and abdominal computed tomography (CT) showed urinary extravasation. Magnetic resonance imaging (MRI) and retrograde pyelography (RP) demonstrated stenosis of the ureter.

[The significance of urine cytology three consecutive days after transurethral resection as a predictor of superficial bladder cancer recurrence].

To determine whether there was any correlation between recurrence of superficial bladder cancer and the results of urinary cytology examined for 3 consecutive days after transurethral resection of the bladder cancer (TURBT), we retrospectively studied 64 patients with newly diagnosed Ta/T1 transitional cell carcinoma (TCC) of the bladder who had previously undergone TURBT. Urine cytology samples were reported as negative (class I, II) or positive (class III, IV, V). We used the Kaplan-Meier method to calculate the non-recurrence rate, and Cox-proportional hazard models to determine the prognostic significance of clinical and pathological findings.

Inhibition of growth of human prostate cancer xenograft by transfection of p53 gene: gene transfer by electroporation.

To date, there is no effective therapy for hormone-independent prostate cancer. Therefore, as a new strategy for refractory cancer, gene therapy is showing increasing promise. In this study, we attempted to use a nonviral gene transfer system, in vivo electroporation, in prostate cancer cell PC-3 xenografts with the wild-type p53 (wt-p53) gene, as gene therapy for hormone-independent prostate cancer.
