    Objective: To investigate the outcomes of robot-assisted radical cystectomy, intracorporeal urinary diversion, and extended lymph node dissection in patients with muscle-invasive bladder cancer who underwent neoadjuvant chemotherapy. Materials and Methods: A total of 14 patients underwent neoadjuvant chemotherapy for invasive bladder tumors, followed by robot-assisted radical cystectomy, extended lymph node dissection, and intracorporeal urinary diversion. Demographic, operative, and postoperative information of the patients was retrospectively evaluated. Gemcitabine plus cisplatin and cisplatin plus etoposide regimens were used as neoadjuvant treatments. Early and late-term complications were recorded. Results: In the early postoperative period (0-30 days), Clavien-Dindo grade 2 complications occurred in 6 patients and grade 3 complications in 2 patients. In the late postoperative period (31-90 days), Clavien-Dindo grade 2 complications occurred in 1 patient and grade 3 complications in 1 patient. The mean follow-up period was 15.5±5.7 months. Conclusion: Although the intracorporeal technique is more demanding in terms of learning and use, preoperative chemotherapy application should not be seen as a limitation in the application of this technique

    Clinical aspects of renal cell carcinoma

    Renal cell carcinoma (RCC) represents a heterogeneous group of tumors, the most common of which is clear cell adenocarcinoma. RCC accounts for 3% of adult tumors. The incidence has increased more than 30% over the past two decades. It is generally postulated that the increased incidence rates reflect earlier diagnosis at an earlier stage, largely due to more liberal use of radiological imaging techniques. However, advanced disease has also been diagnosed more frequently and the mortality rate has increased as well. Prevention of RCC should focus on smoking cessation and maintaining ideal body mass index. Familial forms of kidney cancer have been described on four distinct histological patterns: clear cell, papillary, chromophobe, and oncocytoma. Genetic forms afflict individuals at an earlier age with a multifocal and recurrent pattern; therefore, nephron-sparing procedures should be the treatment of choice for these patients. The yield of screening the general population for RCC is still relatively low and hence not cost-effective. Screening should be reserved for individuals who carry high risk for RCC. The classic triad of flank pain, macroscopic hematuria, and palpable abdominal mass is now detected in fewer than 10% of patients, and is a late sign. Today, most tumors are diagnosed incidentally. Paraneoplastic syndromes have been reported in 10-40% of patients and can be seen at any stage of disease. The indications and application of percutaneous biopsy for renal masses are limited and mainly used to make differential diagnosis with an infectious process, lymphoma and metastases to the kidney. © 2003 Elsevier B.V.

    İstanbul Bilim Üniversitesi, Tıp Fakültesi.INTRODUCTION Incidence of prostate rhabdomyosarcoma in adults is not yet known. Together with other sarcoma subtypes they cover less than 0.1% of the primary prostate malignancies.(1) We report an adult patient diagnosed with localized rhabdomyosarcoma treated with radical prostatectomy alone
