Bladder cancer group represents patients attending or hospitalized in Urology department, Reims University Hospital and in whom, tumor is visualized during cystoscopy and confirmed by the histological examination of entire resected lesion after Trans Urethral Resection of Bladder Tumor (TURBT).

Control group includes patients consulting for cystoscopy examination in Urology department, Reims University Hospital without any tumor visualization during cystoscopy examination.

Urine vibrational analysis

This study aims to evaluate the performance of vibrational spectroscopy (Infrared and Raman spectroscopy techniques) in bladder cancer diagnosis using urine samples.

Urologic cancers affect the organs and structures of the male and female urinary tract and the male reproductive system. Bladder cancer (BCa) is the second urological cancer in incidence after prostate cancer and represents the 10th most common cancer in the world. This cancer has high recurrence and progression rates. Cystoscopy and urine cytology are the current gold-standard examination for bladder cancer. Nevertheless, the first is invasive and the latter has low sensitivity especially for low-grade bladder cancer. Therefore, it is critical to implement accurate, non- invasive and sensitive examination tool to diagnose patients with bladder cancer at an early stage.

On the one hand, urine is collected non-invasively and considered as a proximal biofluid from bladder. On the other hand, vibrational spectroscopy including Infrared and Raman spectroscopy is widely used for the analysis of biological samples and provides a molecular fingerprint of the sample with minimum or no sample preparation. Applied on urine, this technique may offer interesting alternative for bladder cancer diagnosis and monitoring. Hence, this research project aims to evaluate the analytical capabilities of urinary vibrational spectroscopy with the objective of developing a diagnostic test for urothelial bladder cancer.

The study is planned for 36 months. Patients that approve their participation in the study will respond to a questionnaire allowing us to have clinical information. From these patients, urine samples will be collected in Urology department of Reims University Hospital. Urine samples will be directly analyzed by Fourier Transform Infrared Spectroscopy and/or Surface-enhanced Raman spectroscopy then stored at -80°C for further analysis.

The Leicester Cough Questionnaire in Mandarin Chinese (LCQ-MC) was used to evaluate the degree of cough in patients. The LCQ-MC is divided into three dimensions: physical, psychological and social. There are a total of 19 questions, and each question has seven options (positive scoring, grades 1-7; the higher the score is, the lighter the cough).

To explore the related factors of cough after Uniport video-assisted thoracoscopic surgery pneumonectomy, and to provide theoretical basis and social accumulation of new knowledge for the diagnosis and treatment of cough after pneumonectomy in the future.

Intractable cough after thoracoscopic pneumonectomy is one of the common complications after pneumonectomy. The incidence of cough can reach 25% ≤ 50%. Cough after operation can aggravate the pain of incision, prolong the hospitalization time, increase the cost of hospitalization, affect the conversation and even sleep of the patients, increase the psychological burden of the patients, and reduce the quality of life of the patients accordingly. Therefore, through this study, the investigators hope to understand the related factors of cough after thoracoscopic pneumonectomy and whether there are predictable risk factors, so as to provide theoretical basis for reducing the occurrence of cough after pneumonectomy.

Multivariate Analysis of Cough After Uniport Video-assisted Thoracoscopic Surgery Pneumonectomy

The Leicester Cough Questionnaire in Mandarin Chinese (LCQ-MC), which assesses the cough-related quality of life, consists of 19 items divided into three domains: the physical (8 items), psychological (7 items) and social (4 items) domains. A 7-point Likert scale was used to score individual domains. The total scores ranged from 3 to 21, with a higher score indicative of a better health status
