Ureteral stent exchange under fluoroscopic guidance using the crochet hook technique in women.

Purpose: We developed a method for ureteral stent exchange in female patients under fluoroscopic guidance using a crochet hook technique (CHEX).

Patients And Methods: A total of 45 female patients (51 stents) underwent exchange of ureteral stents. In these patients, 21 ureteral stents were exchanged using CHEX.

[A single center experience with a lithotripsy machine "Modulith SLX-F2" : evaluation of dual focus system and clinical results].

We evaluated the usefulness of a new shock-wave lithotripsy machine with a dual focus system (large focus : 9x50 mm, standard focus : 6x28 mm), "Modulith SLX-F2" on 361 patients. In the first period, 210 patients, were treated with the large focus, and in the second period, 151 patients were treated with the standard focus. Complications, efficacy and subsequent auxiliary procedures were compared between the first and second periods.

[Clinical assessment of ammonium acid urate urinary calculi].

We investigated the patients with ammonium acid urate (AAU) calculi in relation to dietary history, habit and lifestyle. From April, 2002 to March, 2009, AAU calculi were found in 9 patients (0.66) out of 1,365 cases of stones.

[A clinical study concerning survival of operative cases for the transitional cell carcinoma of the upper urinary tract].

To identify prognostic factors influencing survival in transitional cell carcinoma (TCC) of the upper urinary tract, we retrospectively studied 189 (median age 70, 130 males and 59 females) patients who underwent surgical resection at our 3 hospitals from August 1980 to September 2006. After a median follow up of 47.8 months, 45 cases (23.

[Multi-center trial on the early effects of silodosin on lower urinary tract symptoms associated with benign prostatic hyperplasia].

Silodosin (URIEF), a new so-called 3rd generation alpha-1 blocker, is widely expected to be effective and useful for lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH), due to its high specificity to alpha-1A receptor. We evaluated the efficacy of Silodosin, on 187 males 50 years old or over with the diagnosis of BPH. Silodosin significantly improved the International Prostate Symptom Score (IPSS) and quality of life (QOL) score from the day after administration was started.

[A case of hormone/docetaxel-refractory prostate cancer in which PSA level decreased after docetaxel+zoledronic acid treatment].

The patient was a 63-year-old man who had a recurrence and bone metastasis of prostate cancer after total prostatectomy. He was diagnosed with prostate cancer refractory to hormones. Subsequently, the PSA level decreased after docetaxel therapy, but then gradually increased.

[Retroperitoneal Castleman's disease presenting characteristic image finding].

A 30-year-old woman was hospitalized in our institute with fever up and abdominal pain. Computerized tomography showed a retroperitoneal mass (8 cm in diameter) with arborizing calcification, which was enhanced homogeneously in the arterial phase. The operation was performed and parthological diagnosis revealed hyaline vascular type Castleman's disease.

[Two cases of renal cell carcinoma with diabetes mellitus that was healed after nephrectomy].

Two cases of renal cell carcinoma presenting with uncontrolled diabetes mellitus are reported. A 61 and 64-year-old women with hyperglycemia were incidentally found to have a right renal tumor. Laboratory investigation of both cases revealed glucose of 324 mg/dl and 357 mg/dl, HbAlc of 9.

[Three cases of pulmonary hamartoma appearing after radical nephrectomy for renal cell carcinoma].

We report 3 patients with pulmonary hamartoma, all of whom had undergone nephrectomy for renal cell carcinoma. A lung tumor was detected 2 to 9-months following nephrectomy. Preoperative diagnosis was pulmonary metastasis from renal cell carcinoma and pulmonary tumor resection was performed in each case.

[Effectiveness of neoadjuvant chemotherapy for the patients with locally invasive bladder cancer].

Objective: To know the survival and prognostic factors of the patients who received radical cystectomy with or without neoadjuvant cisplatin-based chemotherapy.

Methods: Between 1977 and 2001, 201 patients underwent radical cystectomy at Yokohama City University and Yokosuka Kyosai Hospital whose tumor were clinically diagnosed as locally invasive bladder cancer (T2-4NxM0). Survival rates and 9 prognostic factors (Age, Size, Multiplicity, Type, Grade, p-stage, n,neoadjuvant chemotherapy, adjuvant chemotherapy) were analysed by Kaplan-Meier methods and Cox-proportional hazard model.

[Results of adjuvant intravesical Bacillus Calmette-Guérin therapy for grade 3 superficial bladder cancer].

To examine the incidence of recurrence, progression and survival in patients with grade 3 superficial bladder cancer after transurethral resection (TUR) and adjuvant intravesical instillation of Bacillus Calmette-Guérin (BCG), we retrospectively studied 39 patients with grade 3 superficial bladder cancer. Nineteen patients with high-grade superficial bladder cancer (pTa, pT1) and 5 patients with grade 3 carcinoma in situ (CIS) received intravesical instillation of BCG after transurethral resection of the bladder tumor (BCG group and CIS-BCG group). The Tokyo 172 strain BCG was given for 8 weeks, as a rule, in a dose of 80 mg in 40 ml of saline instilled into the bladder.

[A case of primary choriocarcinoma of the bladder].

A 75-year-old man visited our hospital presenting with gross hematuria. Cystoscopy revealed a bladder tumor with coagulated blood and necrotic tissue at the dome. We resected the bladder tumor transurethrally.

[Squamous cell carcinoma of the ureter arising seventeen years after total cystectomy for squamous cell carcinoma of the bladder: a case report].

We report a case of squamous cell carcinoma of the ureter. A 62-year-old woman had undergone total cystectomy and ileal conduit because of squamous cell carcinoma of the bladder when she was 44 years old. Seventeen years later, she complained of edema and oliguria.
