Transurethral Ventral Wall of Urethra-preserving Enucleation of Prostate

March 12, 2010 updated by: Southwest Hospital, China
In this study, the investigators designed a randomized and double-blind prospective trial to evaluate the efficiency and safety of the investigators new approach-transurethral ventral wall of urethra-preserving enucleation of prostate in comparison with TURP for the hyperplasia weighing more than 45 g.

Study Overview

Indicates the current recruitment status or the expanded access status.

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

Although in recent dozen of years, laser operation and other safer minimally invasive surgeries have been well-developed, transurethral resection of the prostate (TURP) is still the gold standard for the surgical treatment of benign prostatic hyperplasia, despite of its various complications, and not suitable for the hyperplasia over 80 g which should be resected under open surgery. In this study, we design a randomized and double-blind prospective trial to evaluate the efficiency and safety of our new approach-transurethral ventral wall of urethra-preserving enucleation of prostate in comparison with TURP for the hyperplasia weighing more than 45 g.Urodynamic examination [maximum flow rate (QMax), detrusor pressure, and so on], transrectal color Doppler ultrasonography for the prostate, blood routine, blood electrolyte, prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), the quality of life (Qol), blood loss during operation, and the weight of resected prostate were studied before and after the operation.

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.
