Study summary

The goal of this study is to evaluate the safety and oncological outcomes of single chemotherapy bladder instillation following endoscopic treatment for UTUC in UTUC suspected patients .The main aim is to determine the efficacy of a single, post URS, chemotherapy bladder instillation to reduce IVR.

Participants will be given single chemotherapy bladder instillation within 24h following ureteroscopy and will follow routine follow-up for IVR which will include white light cystoscopy ;patients with suspected IVR (based on either imaging or cystoscopy) will undergo TURBT.

Read the detailed description

URS is routinely used for both diagnosis and treatment of UTUC - it is used either as an initial diagnostic procedure or as a curative procedure in cases amenable for endoscopic tumor ablation; either with low-risk disease or an imperative indication due to impaired renal function.

Following extirpative surgery patients are prone to IVR. Those patients undergo routine follow-up with cystoscopy and in cases of IVR require TURBT and further management based on bladder cancer protocols. In this setting, a single post-operative bladder instillation with various chemotherapeutic agents has shown a significant reduction in IVR rates following RNU.

Retrospective evidence suggests there is an increase IVR rates following URS for UTUC.

In this study the investigators seek to evaluate the efficacy of a single, post URS, bladder instillation with chemotherapy to reduce IVR.

Inclusion criteria

  • Radiographic and/or cytological suspicion for UTUC
  • Planned endoscopic procedure for treatment / diagnosis of UTUC
  • Patients with bladder cancer history are eligible if meeting both following criteria:

No recurrence within the last two years Are not on active bladder irrigation protocol

  • Patients with history of UTUC are eligible if last endoscopic treatment or RNU was >1 year prior to enrollment
  • Age ≥ 18 years
  • Performance status 0-2

Exclusion criteria

Exclusion Criteria:

  • Subjects who have had bladder / prostate radiotherapy
  • Subjects with bladder cancer history on active bladder irrigation protocols or with active disease within two years prior to enrollment
  • Subjects with previously treated UTUC within one year prior to enrollment
  • Subjects with disease
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 20, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
