Suprarenal Filter Placement in the Inferior Vena Cava to Prevent Tumor Emboli During Radical Nephrectomy in Renal Cell Carcinoma Invading the Inferior Vena Cava / 대한비뇨기과학회지

A renal cell carcinoma with tumor thrombus extension into the inferior vena cava occurs in approximately 5 percent of cases. Despite invasion of the inferior vena cava, an aggressive surgical approach for these neoplasms is recommended, but pulmonary and tumor embolisms have been common complications. Therefore, the prevention of tumor emboli during operation is necessary. Placement of a suprarenal filter in the inferior vena cava has become the procedure of choice for preventing tumor emboli during a radical nephrectomy.

Post Prostatectomy Prognostic Factors in Patients with Acute Urinary Retention due to Benign Prostatic Hyperplasia / 대한비뇨기과학회지

PURPOSE: Multiple parameters were preoperatively examined to determine if any could predict successful voiding after a prostatectomy in male patients presenting with acute urinary retention due to a benign prostatic hyperplasia. MATERIALS AND METHODS: A total of 93 men, between 58 and 87 years old (mean age 72.9 years), who presented with acute urinary retention were investigated pre and post-operatively with an urodynamic study, transrectal ultrasonography (TRUS) and a completed International Prostatic Symptom Score (IPSS). RESULTS: 3 months postoperatively, 6 patients (15.8%) with detrusor hyporeflexia or detrusor instability required clean intermittent catheterization to empty their bladders. All patients with a prostate volume over 40 gm were able to void without catheterization after the prostatectomy. The IPSS, age, residual urine, cystoscopic findings, preoperative creatinine and resected prostate weight were not predictive of voiding failure after a prostatectomy. CONCLUSIONS: The urodynamic study and TRUS findings are important predictors of the improvements in symptoms and flow rates for the acute urinary retention associated with a benign prostatic hyperplasia.

Gangioneuroma Misdiagnosed as Ovarian Tumor / 대한비뇨기과학회지

A ganglioneuroma is a rare neoplasm in adults, which is most commonly locating in the posterior mediastinum, but can also be located in the retroperitoneum, pelvis, adrenal medulla and neck. They predominantly occur in females, with 60-70% of diseases originating before the age of 20 years. Herein, a case of a 51-year-old woman suffering from a pelvic mass, with a history and physical findings similar to those of an ovarian tumor, is reported.

Hematologic Toxicity of Gemcitabine and Cisplatin Combination Therapy in Advanced Urothelial Cancer / 대한비뇨기과학회지

PURPOSE: To evaluate the hematologic toxicity of gemcitabine and cisplatin (GC) in patients with advanced transitional cell carcinomas. MATERIALS AND METHODS: From 25 patients, with advanced transitional cell carcinomas, 8 had previously received M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) chemotherapy for a metastatic disease, and were scheduled to receive gemcitabine, 1,000mg/m2, intravenously, over 30 minutes, on days 1, 8 and 15, and cisplatin, 70mg/m2, over 1 hour, on day 2 of a 28-day cycle. The hematological toxicities of each cycle were evaluated. RESULTS: The main hematological toxicities were thrombocytopenia (grade 3 in 24% and grade 4 in 16% of patients), leukopenia (grade 3 in 14% of patients) and anemia (grade 3 in 12% of patients). Four of the patients that experienced grade 4 thrombocytopenia had a tendency for recurring grade 4 thrombocytopenia during the GC chemotherapy. However, there was no evidence of bleeding. CONCLUSIONS: The most severe hematological toxicity of the GC chemotherapy was thrombocytopenia. The careful observation of the patients that experience grade 4 thrombocytopenia is recommended.
