Bladder tumor staging: comparison of contrast-enhanced and gray-scale ultrasound
2009
OBJECTIVE. The purpose of this study was to evaluate the effectiveness of contrast-enhanced sonography in comparison with conventional sonography in differentiating muscle- infiltrating and superficial neoplasms of the urinary bladder. SUBJECTS AND METHODS. Conventional and contrast-enhanced sonography were performed on 34 consecutively registered patients with bladder tumors. All examinations were reviewed by two independent sonologists. At gray-scale sonography, interruption of the hyperechoic bladder wall was considered the main diagnostic criterion for differentiating superficial and infiltrating tumors. At contrast-enhanced sonography, a tumor was considered superficial when the hypoen…
Laparoscopic removal of mullerian duct remnants in boys
2003
Abstract: Purpose: Mullerian duct remnants (MDRs) are present in a male pseudohermaphroditic form characterized by failure of the mullerian duct to regress due to insufficient production or peripheral action of mullerian inhibiting substance. The MDR can be asymptomatic but it often results in infections, stones and voiding troubles. Furthermore, it may develop into a neoplasm. Therefore, surgery is mandatory for large MDRs and symptomatic patients. Laparoscopic removal is described. Materials and Methods: Six males were treated from February 1998 to February 2003. Age at surgery was between 3 and 18 years (mean 8.6). All patients showed severe hypospadias and 2 had mixed gonadal dysgenesis…

An increased body mass index is associated with a worse prognosis in patients administered BCG immunotherapy for T1 bladder cancer
2018
PURPOSE: The body mass index (BMI) may be associated with an increased incidence and aggressiveness of urological cancers. In this study, we aimed to evaluate the impact of the BMI on survival in patients with T1G3 non-muscle-invasive bladder cancer (NMIBC). METHODS: A total of 1155 T1G3 NMIBC patients from 13 academic institutions were retrospectively reviewed and patients administered adjuvant intravesical Bacillus Calmette-Guérin (BCG) immunotherapy with maintenance were included. Multivariable Cox regression analysis was performed to identify factors predictive of recurrence and progression. RESULTS: After re-TURBT, 288 patients (27.53%) showed residual high-grade NMIBC, while 867 (82.8…
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...
The Role of Novel Bladder Cancer Diagnostic and Surveillance Biomarkers—What Should a Urologist Really Know?
2022
The aim of this review is to analyze and describe the current landscape of bladder cancer diagnostic and surveillance biomarkers. We researched the literature from 2016 to November 2021 to find the most promising new molecules and divided them into seven different subgroups based on their function and location in the cell. Although cystoscopy and cytology are still the gold standard for diagnosis and surveillance when it comes to bladder cancer (BCa), their cost is quite a burden for national health systems worldwide. Currently, the research is focused on finding a biomarker that has high negative predictive value (NPV) and can exclude with a certainty the presence of the tumor, considering…
A prospective observational study on oral administration of Ellagic Acid and Annona Muricata in patients affected by non-muscle invasive bladder canc…
2021
Introduction: BCG and MMC shortage and Covid-19 pandemic, more recently, limit accessibility to maintenance regimen in intravesical prophylaxis against recurrence of non-muscle invasive bladder cancer (NMIBC). Ellagic acid (EA) and Annona muricata (AM) exert antitumor activity against different human tumours. An observational prospective study on the prophylactic effect of oral administration of EA+AM in patients avoiding maintenance regimen is presented. Materials and methods: Patients affected by NMIBC and not undergoing maintenance after a 6-week course of intravesical prophylaxis with MMC or BCG were entered. Tis and very high-risk tumours were excluded. After informed consent, the pati…
hTERT mRNA expression in urine as a useful diagnostic tool in bladder cancer. Comparison with cytology and NMP22 BladderCheck Test®
2018
Abstract Introduction To study the relationship between quantitative mRNA determination (hTERT) in patients with bladder tumor, history of bladder tumor, and in subjects without a history of this neoplasia. Material and methods A prospective randomized controlled study with 91 subjects included. The value of mRNA-hTERTN was determined in 63 patients with a history or suspicion of bladder tumor and in 28 controls. Urine samples were sent for evaluation of the mRNA level (hTERT), the cytological study and the NMP22 result. Results Differences were observed in mean hTERTN levels in each of the groups: tumor presence 21.33 ± 40.66, tumor history 2.16 ± 2.67, controls 0.9 ± 1.75 (p Conclusions …
Comparison of three different antibiotic protocols in transurethral resection of bladder tumour and the possible infectious risk factors: A non-rando…
2018
Introduction: We sought to investigate three different antibiotic protocols in transurethral resection of a bladder tumour (TURBT), and the possible infectious risk factors of this surgery.Methods: We conducted a non-randomized, prospective study, gathering cases of patients in whom TURBT had been performed. The sample was divided into three groups based on those who received antibiotics as: a single preoperative dose (Group A); a preoperative dose, plus a long protocol during the hospitalization (Group B); a preoperative dose, plus a long protocol during the hospitalization, plus five days at home (Group C). Intra- and postoperative data that could be relevant to infections was gathered.Re…
