NCT04644835

Brief Summary

The investigators hypothesize that low energy shock wave therapy (LESW) might induce damage to the tumor tissues of non-muscle invasive bladder cancer (NMIBC), so they could be ablated and detached from the surface. The patients who are suffering from NMIBC will be randomly allocated into two groups: The first group (control group): 25 patients will be exposed to sham treatment before transurethral resection of bladder tumor (TURBT) without using LESW therapy. The second group (LESW group): 25 patients will be exposed to LESW therapy before TURBT. The apoptotic effect of LESW will be studied via histopathological examination and molecular studies of the resected bladder tissues. The patients will receive intravesical chemotherapy or BCG immunotherapy and they will be followed up at outpatient clinic for two years by MRI, outpatient cystoscopy and cytology to identify the recurrence and progression rate of NMIBC.

Study Arms (2)

LESW group

EXPERIMENTAL

The shock wave applicator (Dornier AR2, shock wave device, Dornier MedTech 2010, Wessling, Germany) will be gently placed directly on the ultrasound transmission gel over the skin surface of the suprapubic region above the urinary bladder at the site of the papillary lesion (ultrasound guided) and at other five points. Points 1 and 2 will be at the level of transverse crease 2 cm above the pubic bone and 5 cm from each, points 3 and 4 will 2 cm above points 1 and 2, and point 5 will be centered of points 1-4. A total of 2000 pulses at 0.25 mJ/mm2 will be delivered with a frequency of 3 pulses per second. The position of the shock wave applicator will be changed after every 400 pulses.

Device: Low Energy Shock Wave Treatment

Control group

SHAM COMPARATOR

This group of patients will be exposed to the same therapy head, which will also be fitted with a stand-off without energy transmission.

Device: Sham Treatment
