THREE-DIMENSIONAL STEREOTACTIC POSTERIOR ISCHIORECTAL SPACE COMPUTERIZED TOMOGRAPHY GUIDED BRACHYTHERAPY OF PROSTATE CANCER: A PRELIMINARY REPORT

Abstract

The 3-D stereotactic CT guided posterior ischiorectal space approach for brachytherapy is not limited by prostate size, transurethral prostatic resection defects or public arch interference, and it allows for needle verification and correction if necessary. Initial clinical and biochemical results in patients treated with this method are promising.

Less invasive causal treatment of ejaculatory duct obstruction by balloon dilation: a case report, literature review and suggestion of a CT- or MRI-guided intervention

“…In theory, the periprostatic venous- and nerve plexus [21] as well as branches of the internal pudendal artery and the inferior rectal artery within the periprostatic and pararectal fat could be injured. However, 130 patients who received even multiple needles through the posterior ischiorectal space for brachytherapy of prostate cancer had no complications due to hemorrhage [22]. …”

Pelvic Radiotherapy and Sexual Function in Men and Women

“…Brachytherapy was originally introduced not only to limit the detrimental effects of EBRT on bowel and urinary function but also to help preserve sexual function. In general, after permanent seed implantation, ED rates have ranged from 5% to 51%, with the highest percentages found after the combination brachytherapy and EBRT [33,34,[61][62][63][64][65][66][67][68][69][70]. The highest ED rates, ranging from 29% to 89%, have been reported combining the temporary iridium-192 implants with EBRT [34,62,63,65].…”

“…Die tatsächlich applizierte Strahlendosis ist bei einer Zieldosis von 140-160 Gy jedoch erheblichen Schwankungen unterworfen, und kann zwischen 30 und 260 Gy liegen [17]. Transrektaler zweidimensionaler Ultraschall und/oder Röntgendurchleuchtung sind zur exakten Seed-Positionierung unerläßlich, jedoch dürften die aufwendigeren dreidimensionalen bildgebenden Techniken größere Sicherheit bei der Seed-Plazierung bieten [18], und möglicherweise die beobachtete erhebliche Streuung der Strahlendosen bei konventioneller zweidimensionaler Technik vermindern [17].
