Flexible Cystoscopy Compared with Ultrasound in the Detection of Recurrent Bladder Tumours

Abstract

A combination of transrectal and transabdominal ultrasound was compared with flexible cystoscopy as a means of detecting recurrent bladder tumours. The study group comprised 50 patients who had previously had rigid cystoscopy. They underwent combination ultrasound in the out-patient department 1 week before flexible cystoscopy. Combination ultrasound identified 25 patients with recurrent tumours and flexible cystoscopy identified 26. Thirty-four patients (68%) preferred ultrasound, 10 (20%) preferred flexible cystoscopy, 3 (6%) preferred general anaesthesia and rigid cystoscopy and 3 (6%) had no preference. The main objection to ultrasound was the use of the transrectal probe.

Comparison of Virtual Cystoscopy and Transabdominal Ultrasonography with Conventional Cystoscopy for Bladder Tumor Detection

“…11 In this study, patients favored the combination of transabdominal and transrectal US over flexible cystoscopy and rigid cystoscopy. They considered the combined US much more comfortable than CC.…”

“…[11][12][13][14][15] Most studies show that transabdominal bladder US is especially poor in detection of tumors smaller than 5 mm. 12 Another important point is bladder tumor site influences on the US detection rate.…”

“…They considered the combined US much more comfortable than CC. 11 Moreover, CC is invasive, time-consuming, and expensive. Sedation is frequently necessary, and iatrogenic injury to the urethra and bladder may occur.…”

La impresión cistoscópica frente al diagnóstico histológico en los tumores vesicales: ¿Coinciden?

“…Otros estudios han comparado el diagnóstico histológico tras la RTU con las piezas de la cistectomía 2 . Existen estudios que comparan la cistoscopia con técnicas de imagen combinadas como por ejemplo la ecografía abdominal y la transrectal con el fin de reducir el número de cistoscopias 3,4 . Un estudio reciente propone la fulguración endoscópica ambulatoriamente en el seguimiento de las recidivas de los tumores vesicales de bajo grado y estadio, no considerando esencial la biopsia y por consiguiente el diagnóstico histológico en este grupo de tumores 5,6 .…”

MR cystography for bladder tumor detection

“…Since more than 95% of bladder neoplasms are malignant, and 80% of bladder malignancies are polypoid lesions, virtual endoscopy should be a wellsuited diagnostic tool [9]. Moreover, many patients in the follow-up after local bladder tumor resection prefer an examination less invasive and less unpleasant than conventional cystoscopy, which was shown by an investigation comparing the acceptance of cystoscopy and ultrasound for the detection of recurrent bladder cancer [10].…”
