Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Inclusion Criteria:

1. Male and female patients aged 18 to 80 years who have a Ch 4.7-6.0 polyurethane ureteral stent

Exclusion Criteria:

  1. Active phase of urinary tract infection
  2. Insufficient level of social adaptation
  3. The patient does not have a smartphone with Internet access

All patients will be randomized into 2 groups:

  • group A - patients who used the Stone MD mobile application
  • group B - patients who did not use the mobile application Patients are to be assigned a randomization number that will match their treatment. Block randomization using 10 blocks is to be performed by a central randomization organization (www.randomize.net) using a computerized algorithm.

"Stent Radar" - part of the "Stone MD" mobile application. This tool is designed for the patient to remove the ureteral stent using a mobile application within the time period prescribed by the doctor. After the operation, the patient independently enters the data related to the installation of the stent in the Stent Radar section of the Stone MD mobile application. This data includes: the name of the stent, the side of insertion, and the estimated date of removal. In a few days, a push notification appears in the application stating that it is necessary to consult a doctor for the timely removal of the stent. Thus, it is almost impossible to forget to remove the stent.

At discharge, we strongly recommend that all patients install the Stone MD mobile app on their smartphone. In the postoperative period, all patients will be monitored. In the event that 2 weeks after the expected date of removal, the patient does not get in touch, he will receive a call from the clinic, reminding him of the necessary visit (to remove the stent).

Primary assessed outcomes:

  1. Number of patients who removed the stent on time in both groups
  2. Number of patients who delayed stent removal in both groups (less than 14 days)
  3. Number of patients who forgot to remove the stent in both groups (removed the stent more than 14 days from the expected date of removal)

Secondary assessed outcomes:

1. Assessment of Stone-free status after surgery by performing computed tomography of kidneys and urinary tract without intravenous contrasting 1 month after surgery

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers
