Introduction: To identify risk factors for biochemical failure after radical prostatectomy (RP) in men with pathologically organ-confined (OC) prostate cancer (PCa). Materials and Methods: Clinical and pathological features of 350 consecutive patients with pathologically OC PCa treated only with RP and bilateral pelvic lymphadenectomy were analyzed, retrospectively, to identify predictor parameters of prostate-specific antigen (PSA) failure (PSA ≧0.4 ng/ml). The median follow-up was 58.6 months (range: 3.9–183 months). All pathological specimens were step sectioned at 4-mm intervals. Kaplan-Meier progression-free survival rates and χ2 test were adopted for statistical analyses. Multivariate Cox proportional hazard regression models were used to test the association between pathological Gleason score and surgical margin status. Results: 67 patients (19.1%) failed at a median follow-up of 40.2 months (range 1.9–123.3). Age and preoperative PSA failed to reveal significance also in patients with serum PSA ≧20 ng/ml (p = 0.46). Patients with T3 clinical stage had a higher progression rate compared to T1C and T2 (43.5 vs. 27.8 and 17.3%, respectively) even if no high statistical significance was pointed out. Presence of perineural infiltration (p = 0.04) and prostatic apex infiltration (p = 0.74) in the prostatectomy specimens failed to reveal significance. A high pathological Gleason score (≧7; p = 0.0003) and surgical margin status (p < 0.0001) were shown to be the most powerful predictive parameters of biochemical progression. Conclusions: In patients with pathologically OC PCa the presence of a high pathological Gleason score and positive surgical margins appear to represent the most important factors for prediction of outcome following RP.
In our experience, even if on a limited number of patients, the application of ICG with NIR fluorescence during RARP is helpful to identify the benchmark artery of neurovascular bundle.
Although nephrolithiasis is a more common disease in men rather than women, several studies over the last decades show that the male to female ratio 3:1 is narrowing. These finding may be associated to modified risk factors for stone formation between females and males. Changes in lifestyle and increasing obesity in women may play a role in shifting of gender disparity. Furthermore, recent studies have demonstrated an increase of kidney stones in women which have necessitated emergency department visits (ED). Therefore, females show a greater percentage of mortality rate if compared to males, especially if stone disease is associated to urosepsis and requires the admission to the Intensive Care Unit (ICU). This article reviews recent insights into changing gender prevalence in urinary calculi and into identifying the relation between gender and risk factors for stone disease, that in case of severe urosepsis might also lead to mortality.
Objectives: The present study was carried out to evaluate the effectiveness of medical therapy with potassium citrate in preventing calculosis complicating Medullary Sponge Kidney (MSK) without renal acidification defects.Materials and methods: In a open, uncontrolled, retrospective analysis, 49 MSK patients with nephrolithiasis without renal tubular acidosis, underwent a complete metabolic evaluation and received potassium citrate therapy 4-6 g/day. The course of stone disease before and after citrate therapy was determined in each patient from a combination of clinical history, past records, radiographs and kidney ultrasound. The rate of new stone formation/pt/yr, of endourological and extracorporeal procedures, of urinary tract infection (UTI) and number of hospitalization before and after medical treatment were calculated. Results: Metabolic anomalies (hypercalciuria, hypocitraturia, hyperuricuria and hyperoxaluria) were present in 83% of the patients. Follow-up before and after alkali citrate therapy was comparable (4.7+/-1.4 and 4.9+/-1.7 years respectively). Medical treatment significantly reduced rates of stone formation from 2.0+/-1.0 to 0.2+/-0.5 pt/yr, ureteroscopy (URS) from 0.9+/0.8 to 0.4+/-0.5 pt/yr, extratracoporeal lithotripsy (ESWL) from 1.1+/-0.8 to 0.4+/-0.6 pt/yr, urinary tract infections (UTIs) from 0.8+/-1.2 to 0.3+/-0.5 pt/yr and hospitalization from 1.1+/-0.6 to 0.2+/-0.3 pt/yr, p < 0.001. This effect was observed also in MSK patients without metabolic anomalies. In 35 patients the asymptomatic disappearance of calcium stones was also observed. Conclusions: Our study documents the effectiveness of potassium citrate therapy in preventing neprolithiasis in MSK patients also in the absence of distal tubular acidosis. It suggests that in MSK patients alkali citrate may promote calcium stone dissolution by oral administration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
