PURPOSE: Ureteric stents are frequently used in urology practice and can cause significant impairment in quality of life (QoL). The aim of this study was to validate the Ureteral Stent Symptoms Questionnaire (USSQ) to be used in the evaluation of stent-related symptoms and impairment in QoL in Turkish-speaking patients. METHODS: After linguistic validation of the original USSQ into Turkish language, the Turkish version of the USSQ (T-USSQ) was self-administered to all participants at week 1 and 4 after stent placement for test-retest reliability and internal consistency and at week 8 (4 weeks after stent removal) for sensitivity to change analysis...

The detection of neoplastic lymph nodal involvement in prostate cancer (PCa) patients has relevant therapeutic and prognostic significance, both in the clinical settings of primary staging and restaging. Lymph nodal dissection (LND) currently represents the gold standard for evaluating the presence of lymph nodal involvement. However, this procedure is invasive, associated with morbidity, and may fail in detecting all potential lymph nodal metastatic regions. Currently the criteria for lymph nodal detection using conventional imaging techniques mainly rely on morphological assessment with unsatisfactory diagnostic accuracy...

INTRODUCTION: In 1979, the Copenhagen group around Dr. Skakkebaek introduced contralateral biopsy in patients with testicular germ cell tumour (GCT) as a means of early diagnosing a contralateral testicular tumour (Berthelsen et al. in Br Med J 2(6186):363-364, 1). Although the rationale of contralateral biopsies is based on much of scientific evidence, no issue regarding the management of GCTs has been more controversial than the issue of contralateral biopsies (Heidenreich in BJU Int 104(9 Pt B):1346-1350, 2; Grigor and Rorth in Eur Urol 23(1):129-135, 3)...

PURPOSE: To determine whether sentinel node detection (SNd) in muscle-invasive urothelial bladder cancer (MIBC) can be performed in patients undergoing neoadjuvant chemotherapy (NAC) and determine whether SNd is feasible in all pT stages, including pT0. BACKGROUND: Previous published series of SNd in MIBC have not included patients undergoing NAC, and systematic reports of pT0 patients w/wo NAC were absent. Translational immunological tumor research on MIBC focusing on SNd, in the era of NAC, requires technical feasibility...

Over the past two decades, the use of well-validated, guideline-based strategies resulted in high cure rates in patients with germ-cell cancer (GCC) often despite widespread metastatic disease at initial presentation. Yet, about 30 % of patients diagnosed with metastatic disease corresponding to about 5-10 % of GCC patients overall will experience disease progression or recurrence at some time point of their disease with the need for salvage treatment. Salvage treatment is more complex and less well validated than first-line treatment: Its rare patient cohorts are more heterogeneous and prognostic factors impact more compared to other treatment scenarios...
