Active clinical trials for "Dilatation, Pathologic"

We proposed that silodosin administration preoperatively may facilitate ureteral access sheath (UAS) placement prior to flexible ureteroscopy (F-URS) and decrease the incidence of ureteric injury in some difficult cases.

The purpose of this randomized trial is to compare same-day cervical preparation using Dilapan-S™ plus buccal misoprostol to overnight cervical preparation using Dilapan-S™ before D&E at 16.0 to 20.0 weeks. Primary objective: To compare D&E operative time. We hypothesize that same-day Dilapan-S™ plus buccal misoprostol is non-inferior to overnight Dilapan-S™ with respect to operative time. Secondary objectives: To compare treatment groups for the following: Pre-operative cervical dilation; need for mechanical dilation and ease of dilation if required; ability to complete D&E without further cervical preparation; ease of D&E; complications; pain; side effects; patient and provider satisfaction.

This study evaluates the usefulness and safety of using a balloon to dilate (make larger) the Eustachian tube in adults who have middle-ear disease due to Eustachian tube dysfunction.

The purpose of this research study is to compare three different ways of opening a woman's cervix before her second-trimester surgical abortion. Osmotic dilators: small rods that, when inserted into the cervix, gently expand to open the cervix Osmotic dilators plus mifepristone, a medicine that is swallowed Osmotic dilators plus misoprostol, a medicine that is placed between the cheek and gum Hypotheses: adding buccal misoprostol 3 hours preoperatively will significantly improve dilation compared to laminaria alone, making procedures faster, easier and safer. adding oral mifepristone at the time of laminaria placement will confer a similar benefit. the efficacy of adjunctive misoprostol and mifepristone will be influenced by gestational age, with women later in gestation having increased efficacy from these agents. significantly more patients who receive adjunctive misoprostol or mifepristone will have adequate initial dilation, fewer will require manual dilation or additional cervical preparation and there will be fewer complications in these arms, although complication rates will be low and we will only be able to detect relatively large differences. patients will prefer to have the procedure done as quickly as possible with as little discomfort as possible, that cervical ripening with adjunctive misoprostol will be associated with more cramping than osmotic dilators alone and that mifepristone will be well tolerated and may not cause more cramping or other side effects than osmotic dilators alone.

The purpose of this study is to show clinically meaningful improvement in symptom severity after transnasal balloon dilation of the maxillary sinus outflow tract with or without balloon dilation of the frontal or sphenoid sinuses.

The objective of this randomized clinical trial is to compare pain levels during and after insufflation with carbon dioxide or in subjects that will undergo endoscopic fulguration with argon to reduce the diameter of the gastrojejunal anastomosis. The investigators hypothesize that carbon dioxide will be superior in causing less pain and leading to less discomfort.

The purpose of this study is to determine how different endoscopic papillary balloon dilatation (EPBD) duration time affects the complications after endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of common bile duct stones.

The purpose of this study is to evaluate the effectiveness of ARTHRO distension plus intensive mobilisation in shoulder capsulitis.

The investigators are conducting a study on pain control for dilation and curettage (D&C). Participants are eligible to enroll if they are a planning to have a D&C in a participating clinic. The investigators are studying how different ratios of medication to liquid affect pain when injected around the cervix. Both potential methods use the same dose of medication, though researchers would like to know which one works better. To be in this study, participants must be over the age of 18 with an early pregnancy loss or undesired pregnancy measuring less than 12 weeks gestation undergoing D&C while awake in clinic.

A prospective, single-arm, post approval pilot study.
