Dorsal Root Ganglion Stimulation: A Treatment Option for Chronic Pain Due to Refractory Loin Pain Haematuria Syndrome

Neurophysiological Effects of Dorsal Root Ganglion Stimulation (DRGS) in Pain Processing at the Cortical Level

“…Morgalla et al reported 63.5% overall pain relief and improvement in BPI scores under DRGS in patients with post-herniorraphy inguinal pain, which was sustained even after three years of observation (14). These successful rates of pain relief have been replicated in other more recent smaller case series (11,55,56) as well as in some case reports (13,16,18,19,26). In our study, we had 74% mean pain reduction at one month and 70% at six-month postsurgery.…”

“…In 2011, dorsal root ganglion stimulation (DRGS) was introduced for the treatment of NP (9). Since then, numerous publications have shown positive clinical results using DRGS for chronic NP (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28).…”

<p>Neuromodulation with electrical field stimulation of dorsal root ganglion in various pain syndromes: a systematic review with focus on participant selection</p>

“…Included studies analyzed the following painful conditions: CRPS,1–3,31–36 LBP,5,6,37–40 groin pain,7,8,41 pelvic girdle pain,9,10 peripheral neuropathy,29,30,42 peripheral diabetic neuropathy,43 phantom limb pain,44 chronic intractable pain in the coccyx,45 chronic testicular pain,46 anterior cutaneous nerve entrapment syndrome (ACNES),47 loin pain hematuria syndrome (LPHS) 48…”

“…Other pain conditions treated with DRG stimulation were chronic intractable pain in the coccyx with 90% pain reduction at 4 months,45 chronic testicular pain with sustained pain reduction of 70%–80% during 1 year,46 and LPHS with >50% pain relief after 3 years 48. These case reports included only one participant.…”

Utilização de potenciais evocados a laser para avaliação da dor neuropática crônica durante a estimulação do gânglio da raiz dorsal

“…menos conexões centrais), implicando em pouca ou nenhuma habituação, o que pode conferir vantagem adicional ao método sobre outras formas de modulação. Taxas bem-sucedidas de alívio da dor foram observadas em outras séries de casos (Huygen et al, 2017, Mol et al, 2017, van Bussel et al, 2017, Eldabe et al, 2018, Falowski et al, 2018, Hassanain et al, 2018, Kallewaard et al, 2018, Skaribas et al, 2018 bem como em alguns relatos de casos (Garg et al, 2015, Rowland et al, 2016, Zuidema et al, 2016, Maino et al, 2017, Zuidema et al, 2017, Giordano et al, 2018, Goebel et al, 2018, Groenen et al, 2018. Uma série com 217 pacientes avaliados retrospectivamente num estudo multicêntrico demonstrou 66,9% de alivio da dor medida pela EVN durante a triagem quando comparada a linha de base em um grupo de pacientes apresentando diversos tipos de dor neuropática .…”
