..We analyzed the prognostic significance of the histological subtype in renal cell carcinoma...

..Lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) are common problems in middle-aged and older men. Recently, epidemiologic studies have shown significant associations between severity of LUTS and male sexual dysfunction...

....

..In this study, we report on the perspectives for curing prostate cancer in males undergoing radical prostatectomy with Gleason score of 2-6 on prostate biopsy in relation to pre-operative PSA levels...

..The influence of age on the aggressiveness of prostate cancer (PCa) is controversial. This study aims to assess the influence of age in determining the pathological features of biopsies from patients diagnosed with PCa...

..The aim of this prospective study was to compare the advantage of performing prostate biopsy with a greater number of cores using the classic sextant procedure, with the aim of reducing false negative results...

..To determine through preoperative serum PSA level, Gleason score on biopsy and percentage of fragments affected by tumor on biopsy, the probability of involvement of the seminal vesicles...

..Pathologists include the possibility of an IPC in their reports based on the Gleason score and tumor volume. This study determined the accuracy of pathological data in the identification of IPC in radical prostatectomy (RP) specimens...

..We report our results of orthotopic ileal neobladder after radical cystectomy with prostatic adenomectomy with regard to urinary continence, sexual outcome and disease control...

..At the last recurrence, she presented with several papillary lesions throughout the bladder, discovered on control cystoscopy. Transurethral resection revealed a papillary grade 3 transitional-cell carcinoma of the bladder...

..A critical analysis of the outcomes of patients who were studied in clinical series that used this toxin to treat lower urinary tract symptoms related to benign prostatic hyperplasia is also presented...

..CONCLUSION: The Millin technique, as modified by one of the present authors, can significantly control bleeding during and after surgery, and reduce transfusion rates, when compared to the classic transvesical prostatectomy...

..We described the causes of incontinence in a large group of men that developed this unusual complication and analyzed the influence of age on the prevalence of bladder dysfunction...

..For this reason, we designed the present study in order to better understand men's reactions about this method of screening. The aim was to identify possible drawbacks that could be overcome to increase DRE...

..Pathologist should be alert when evaluating immunohistochemical profiles of unusual histologic findings of prostate cancer, mostly in distant sites...
