About this study
Official title: A Prospective, Randomized Trial Comparing Prostate Capsule-sparing and Nerve-sparing Radical Cystectomy in Patients With Bladder Cancer
The purpose of this clinical trial is to determine if prostate-capsule-sparing cystectomy improves functional outcomes without comprising oncologic outcomes in male patients receiving a radical cystectomy. Patients will be randomized to one of two groups: prostate capsule-sparing radical cystectomy or nerve-sparing radical cystectomy. Patients will be monitored following standard of care guidelines and clinical data will be collected. Patients in both groups will be asked to complete an erectile function questionnaire at multiple timepoints. Patients who receive an orthotopic neobladder will be asked to complete a questionnaire to monitor urinary function at multiple timepoints. Patient adverse events will be monitored to ensure patients safety.
Read the detailed description
The purpose of this study is to determine if prostate capsule-sparing cystectomy improves functional outcomes without compromising the oncologic outcomes in patients with bladder cancer. The comparison arm will be patients undergoing nerve-sparing radical cystectomy. Participants will be randomized to receive either a nerve-sparing radical cystectomy or a prostate capsule-sparing radical cystectomy. Patients will be monitored following standard of care guidelines every 3-months post-operatively up to and including 24 months post-operatively. As part of standard of care post-operative follow-up patients will have routine history and physical exams, urine cytology, urine culture, Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), and Prostate Specific Antigen (PSA). Standard of Care diagnostic imaging will also occur. The Sexual Health Inventory for Men (SHIM) Questionnaire will be given to patients 6-weeks post-operatively and every 3-months post-operatively up to and including 24-months post-operatively. To measure urinary function in patients who receive orthotopic neobladder, the Validated Pad Questionnaire will be given 6-weeks post-operatively and every 3-months post-operatively up to and including 24-months post operatively. Adverse Events will be monitored in both groups as defined by the CTCAE 5.0 guidelines.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Functional Outcomes as assessed by the Sexual Health Inventory for Men (SHIM)
Comparison of functional outcomes focusing on preservation of erectile function in patients undergoing cystectomy for bladder cancer. Functional Outcomes will be measured by the Sexual Health Inventory for Men (SHIM) Questionnaire. The Sexual Health Inventory for Men defines the following ranges of Erectile Dysfunction (ED): 1-7 is Severe ED, 8-11 Moderate ED, 12-16 Mild to Moderate ED, and 17 to 21 is Mild ED.
Measured: Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively, 24-months post-op
Secondary outcomes (5)
Change in urinary function in patients with orthotopic neobladder as assessed by the Validated Pad Questionnaire
Urinary function in patient with orthotopic neobladder urinary diversions measured using the Validated Pad Questionnaire. The Validated Pad questionnaire will be used to determine the percentage of patients utilizing 1 to 2 pads versus 2 or more pads for night and day, respectively.
Measured: Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively , 24-months post-op
Change in overall patient survival
Comparing the overall survival of patients in both arms of the study
Measured: Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively, 24-months post-op
Change in disease specific status
Comparing the status of disease specific in both arms of the study
Measured: Baseline, 6 weeks-post operatively, 3-months post-operatively, 6-months post-operatively, 9-months post-operatively, 12-months post-operatively, 15-months post-operatively, 18-months post-operatively, 21-months post-operatively, 24-months post-op
Soft tissue surgical margin rate as assessed by pathology
Pathologists will examine the soft tissue surgical margin rate to determine positive or negative soft tissue surgical margin.
Measured: Up to 4-weeks after surgical intervention
Safety as assessed by adverse events experienced by study participants
Comparing the differences in adverse events (grades 2-5) as experienced by the participants of in each study arm. The grading of adverse events are defined by the CTCAE 5.0 guidelines.
Measured: Up to 24-months post-operative

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this clinical trial is to determine if prostate-capsule-sparing cystectomy improves functional outcomes without comprising oncologic outcomes in male patients receiving a radical cystectomy. Patients will be randomized to one of two groups: prostate capsule-sparing radical cystectomy or nerve-sparing radical cystectomy. Patients will be monitored following standard of care guidelines and clinical data will be collected. Patients in both groups will be asked to complete an erectile function questionnaire at multiple timepoints. Patients who receive an orthotopic neobladder will be asked to complete a questionnaire to monitor urinary function at multiple timepoints. Patient adverse events will be monitored to ensure patients safety.

A study testing Prostate capsule-sparing radical cystectomy and Nerve sparing radical cystectomy in people with Bladder Cancer, run by Johns Hopkins University at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 4 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Armine Smith, MD (202-660-5561, asmit165@jhmi.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
