What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study evaluates and compares two minimally invasive surgical approaches for treating bladder stones in adult patients: transurethral cystolithotripsy (TUCL) and percutaneous cystolithotripsy (PCCL). Urinary bladder stones are commonly managed using endoscopic techniques to avoid the morbidity of open surgery. TUCL accesses the bladder through the natural urinary channel (urethra), whereas PCCL accesses the bladder directly through a small puncture in the lower abdomen above the pubic bone. While both approaches are effective, comparative data in adult populations remain limited. Eligible participants are randomly assigned to receive either TUCL or PCCL. The primary goal is to compare stone clearance rates and operative times between the two procedures. Secondary objectives include comparing surgical complication rates, duration of postoperative urinary catheterization, and length of hospital stay.

Inclusion Criteria: * Adult patients aged 18 years or older * Diagnosed with single or multiple urinary bladder stones * Stone diameter between 1 and 4 cm at its largest diameter or cumulative stone diameter * Candidates for both transurethral and percutaneous endoscopic treatment modalities Exclusion Criteria: * Active urinary tract infection (UTI) * Uncorrected coagulopathy or bleeding disorders * Known urethral stricture or significant urethral pathology precluding safe transurethral instrumentation * History of bladder augmentation, major lower abdominal surgery, or pelvic radiotherapy * Concomitant bladder tumor or suspected bladder neoplasm * Stone located within a bladder diverticulum or within a contracted bladder * Requiring concomitant urological procedures during the same operative session (e.g., transurethral resection of the prostate \[TURP\] or lower ureteric stone extraction) * Urethral stones pushed back into the bladder * Refusal to participate in the study
