Active clinical trials for "Pleural Effusion"

Comparison of complications between standard upper pole percutaneous nephrolithotomy (PCNL) with nephrostomy placement and double J stent and PCNL with double J placement only without nephrostomy.

In recent years, portable and ultra-portable ultrasound devices are increasingly used by the non radiologists, notably cardiologists or obstetrician gynecologist, at the patient's bedside to visualize and measure anatomical structures and fluid and provide the clinical examination with additional signs allowing quicker and more confident clinical decisions. This innovative approach is slowed down by the accessibility of these miniaturized devices, the price of which remains high. The echOpen device includes an ultra-portable ultrasound probe and a mobile application that allows the image to be displayed on a smartphone via a WIFI protocol. The objective of the clinical investigation is to show that the echOpen device, using three frequencies 3.5 Mhz, 5.0 Mhz and 7.5 Mhz, allows identifying the semiological signs or anatomical structures of interest located at several depths of the body, with a performance similar to other devices routinely used in clinical departments.

This is a prospective study to assess the yield of pleural biopsy obtained with the routine flexible thoracoscopic biopsy forceps versus that obtained with a flexible cryoprobe during semirigid thoracoscopy

Undiagnosed pleural effusion is a diagnostic dilemma especially in exudative pleural effusions (EPE). 20-40 % are unable to be attributed to a specific diagnosis, even after thoracentesis and closed pleural biopsy. Thoracoscopy has been demonstrated to increase the diagnostic yield in undiagnosed EPE. The diagnostic yield of thoracoscopy in malignant and TB pleural effusion ranges from 91% to 94% and 93% to 100%, respectively. Rigid thoracoscopy has traditionally been the modality of choice. The recently introduced semirigid thoracoscope provides ease of handling like a flexible bronchoscope. However, there are concerns about the diagnostic yield of semi-rigid thoracoscopy when compared with rigid thoracoscopy. According to the available literature, the yield of semirigid and rigid thoracoscopy is almost similar if adequate pleural biopsy is obtained. However there are concerns that with semi-rigid thoracoscope, there might be greater incidence of inability to obtain adequate pleural biopsy. On the other hand, the use of conventional rigid thoracoscope may be associated with greater procedure related pain.Mini-Thoracoscopy is a newer rigid thoracoscopy instrument which is smaller in diameter (5.5 mm) and may allow pleural biopsy with a smaller incision. There is scant literature on its utility. The investigators hereby propose to undertake a randomized comparison of rigid 'mini thoracoscope' vs semi rigid thoracoscope in undiagnosed pleural effusions.

interventional randomized clinical trial will be done at Assuit University Hospital ( Chest Department and Caridothoracic surgery department ),and all patients presented with complex septate pleural effusion in whom the symptoms excepted to be relieved by pleural fluid drainage will be included in our study within the two next years.

This study will be a prospective, randomized trial comparing a new protocol to the standard of care. The investigators protocol and the standard of care involves a previously established procedure that will be completed in the investigators pulmonary procedure unit. The study will include using previously, well-established procedures (indwelling pleural catheter placement, talc slurry administration through an indwelling pleural catheter, pleuroscopy with talc poudrage administration) in addition to a new protocol (at home continuous drainage via indwelling pleural catheter).

Melanoma antigen (MAGE) gene is known to be expressed in tumor cells, testis and placenta. The purpose of this prospective study was to investigate the sensitivity, specificity and accuracy of pleural fluid MAGE gene expression, tumor marker and cytology in the diagnosis of malignant pleural effusion.

This is a multicentre randomised controlled trial evaluating global health related quality of life outcomes in patients with malignant pleural effusions. Patients will be randomised to receive either chest drain and talc pleurodesis or indwelling pleural catheter and talc pleurodesis. Patients will be followed up for 3 months post intervention

Pleurodesis is a technique used to fuse the two layers of the lining over the lung. This is done to get rid of collections of fluid or air in this space. A common reason would be cancer of the underlying lung or elsewhere causing fluid to collect in the pleural space. In this situation it is a palliative procedure to free the patient from symptoms like breathlessness.

The purpose of this study is to assess the benefit to patients with empyema or complicated parapneumonic effusion (CPE) using a daily versus twice daily Alteplase regimen of two different dose strategies compared with saline placebo.
