PURPOSE A seminomatous element in patients undergoing retroperitoneal lymph node dissection for testicular cancer is associated with a desmoplastic reaction that renders retroperitoneal surgery more challenging. We examined the impact of seminomatous elements on the rate of complications and the need for additional intraoperative procedures in patients(More)
BACKGROUND Sex cord-stromal tumors account for < 5% of all adult testicular tumors, and 10% are malignant. Due to the limited reported experience, there is no agreement on the best management, especially in patients who have tumors with malignant pathologic features or who present with metastatic disease. The authors attempt to evaluate the role of(More)
PURPOSE To assess the impact of multiple access tracts during percutaneous nephrolithotomy (PCNL) on short- and midterm renal function, and to determine risk factors predicting renal function deterioration and/or recoverability. PATIENTS AND METHODS Patients undergoing PCNL with multiple punctures were prospectively enrolled. Preoperative evaluation(More)
PURPOSE Mixed germ cell tumors account for approximately 30% to 50% of testicular tumors. To our knowledge a systematic review with statistical analysis of the associations of histological subtypes in mixed germ cell tumors has not been done previously. It was our impression that such associations exist. Delineating concordant histological types may provide(More)
PURPOSE Post-chemotherapy retroperitoneal lymph node dissection (PC RPLND) is a tool in the management of testis cancer. Our impression has been that the short-term morbidity of standard PC RPLND has diminished with time. Therefore, we attempted to verify this hypothesis by evaluating the morbidity of the procedure in 2 comparable groups of patients from 2(More)
To compare the expression of two promising circulating micro-ribonucleic acids (miRNAs 21 and 221) in patients with prostate cancer to subjects without cancer and to evaluate their potential role as specific noninvasive molecular biomarkers for prostate cancer diagnosis, circulating miRNAs 21 and 221 expression profiles were analyzed in 20 men aged 50–75(More)
OBJECTIVES A number of factors potentially influence the outcome of hypospadias surgery. We evaluate the effect of catheter-size used during urethroplasty (a detail related to the depth of the urethral groove and width/elasticity of the urethral plate) on the complication rate following Duplay-Snodgrass repair. METHODS The data of 113 patients undergoing(More)
OBJECTIVE To evaluate the frequency and potential risk factors for infection-related complications after transrectal prostate biopsy and to propose adjustments in current antimicrobial prophylaxis recommendations. METHODS During 2008-2010, 107 patients underwent transrectal ultrasound-guided biopsies of the prostate at our institution. Charts were(More)
OBJECTIVES To report on the short-term morbidity of radical nephrectomy in 32 patients with poorer performance status and more advanced primary renal cell carcinoma (RCC). Nephrectomy followed by immunotherapy has been shown to improve survival in selected, good performance status patients with metastatic RCC. METHODS We report on 32 patients who(More)
OBJECTIVE To assess the prevalence of renal cysts in a large Middle-Eastern population presenting for a health-screening programme, evaluating cyst characteristics and risk factors for their development. PATIENTS AND METHODS The reported prevalence of renal cysts detected by ultrasonography (US) in the general population is 5.0-20.8%, and their(More)
