Quality of life in women undergoing urinary diversion for bladder cancer: results of a multicenter study among long-term disease-free survivors
2012
Purpose: Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). Materials and methods: All consecutively treated female patients from t…
Matrix Computations for the Dynamics of Fermionic Systems
2013
In a series of recent papers we have shown how the dynamical behavior of certain classical systems can be analyzed using operators evolving according to Heisenberg-like equations of motions. In particular, we have shown that raising and lowering operators play a relevant role in this analysis. The technical problem of our approach stands in the difficulty of solving the equations of motion, which are, first of all, {\em operator-valued} and, secondly, quite often nonlinear. In this paper we construct a general procedure which significantly simplifies the treatment for those systems which can be described in terms of fermionic operators. The proposed procedure allows to get an analytic solut…
THE IMPACT OF NUMBER OF LYMPH NODE REMOVED IN THE DETECTION OF LYMPHNODE METASTASIS: A SENSITIVITY CURVE ANALYSIS.
2014
Scopo del lavoro To assess the correct number of lymph nodes (LNs) to removed at Radical Cystectomy (RC) to ensure an accurate lymph nodes metastasis (LNM) staging. Materiali e metodi Between 1995 and 2012, 1016 RC for bladder cancer (BCa) were completed at a single tertiary care institution. Demographical, clinical and pathological variables were recorded for each patient. The relationship between the number of removed LNs and the probability to find a LNI at definitive pathology examination was assessed by receiver operating characteristic (ROC) analyses. The ROC curve coordinates were used to graph the probability of finding LNI according to the number of LNs removed and examined with a …
Intrauterine device migration into the bladder with stone formation after radiochemotherapy for cervical cancer: a case report
2020
Intrauterine contraceptive device (IUD) is one of the most frequently used contraceptive methods in the world. It is considered a safe and effective method of contraception. However, uterine perfor...
Patterns of Bladder Preservation Therapy Utilization for Muscle-Invasive Bladder Cancer
2016
Background: Trimodality bladder preservation therapy (BPT) in muscle invasive bladder cancer (MIBC) includes a maximal transurethral resection followed by concurrent chemoradiotherapy as an alternative to radical cystectomy (RC) in appropriately selected patients, or as a treatment option in non-cystectomy candidates. Several chemotherapy regimens can be used in BPT, but little is known about current practice patterns. Objective: To describe utilization patterns of BPT and associated survival outcomes in MIBC. Methods: Data were collected from the Retrospective International Study of Cancers of the Urothelial Tract (RISC), a database of 3,024 consecutive patients from 29 international acade…
Alpha-adrenergic drugs in retrograde ejaculation.
1974
6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy (performed because of testicular tumor) were treated with an intravenous injection of 60 mg synephrine. Synephrine stimulates adrenergic alpha-receptors. Only 1 man with sustained retrograde ejaculation improved following treatment showing antegrade ejaculation. This temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder as a result of stimulation of adrenergic alpha-receptors.
Long Term Results of Bladder Exstrophy
1999
After primary bladder closure or urinary diversion, other factors apart from the reconstruction gain importance for individuals with the exstrophy-epispadias complex: social integration and, after reaching puberty, sexuality and fertility.
Electrospun Polyhydroxyethyl-Aspartamide-Polylactic Acid Scaffold for Biliary Duct Repair: A Preliminary In Vivo Evaluation
2017
Abstract Tissue engineering has emerged as a new approach with the potential to overcome the limitations of traditional therapies. The objective of this study was to test whether our polymeric scaffold is able to resist the corrosive action of bile and to support a cell's infiltration and neoangiogenesis with the aim of using it as a biodegradable tissue substitute for serious bile duct injuries. In particular, a resorbable electrospun polyhydroxyethyl-aspartamide–polylactic acid (90 mol% PHEA, 10 mol% PLA)/polycaprolactone (50:50 w/w) plate scaffold was implanted into rabbit gallbladder to assess the in vivo effects of the lytic action of the bile on the scaffold structure and then as a tu…
Clinical use of BCG and its complications: a case series
2021
Bacillus Calmette-Guérin (BCG), a live, attenuated strain of Mycobacterium bovis, is the essential constituent of the vaccine against tuberculosis and the gold-standard adjuvant treatment for urothelial cancer of the bladder. Being a live, attenuated strain with a potential pathogenic action, bacilli can cause several complications, both locally near the inoculation site and remotely through blood dissemination. BCG-related disease can represent a side effect of anti-TB vaccination in patient with congenital or acquired immunodeficiency or a complication of the therapeutic schedule in oncologic patients. Herein we report five cases of BCG-related disease which occurred at the Infectious Dis…
FATTORI PROGNOSTICI NELL'EVOLUZIONE DEL REFLUSSO VESCICO-URETERALE IN ETA' PEDIATRICA
2002
Despite the large number of children with reflux, management among urologists is still controversial. One of the most debacted aspects is the choice between observation treatment or surgical treatment.
