ObjectiveTo compare the effect of corticosteroids combined with local anaesthetic versus local anaesthetic alone during infiltrations of the pudendal nerve for pudendal nerve entrapment.DesignRandomised, double‐blind, controlled trial.SettingMulticentre study.Population201 patients were included in the study, with a subgroup of 122 women.Methods CT‐guided pudendal nerve infiltrations were performed in the sacrospinous ligament and Alcock's canal. There were three study arms: patients in Arm A (n = 68) had local anaesthetic alone, those in Arm B (n = 66) had local anaesthetic plus corticosteroid and those in Arm C (n = 67) local anaesthetic plus corticosteroid with a large volume of normal saline.Main outcome measuresThe primary end‐point was the pain intensity score at 3 months. Patients were regarded as responders (at least a 30‐point improvement on a 100‐point visual analogue scale of mean maximum pain over a 2‐week period) or nonresponders.ResultsThree months’ postinfiltration, 11.8% of patients in the local anaesthetic only arm (Arm A) were responders versus 14.3% in the local anaesthetic plus corticosteroid arms (Arms B and C). This difference was not statistically significant (P = 0.62). No statistically significant difference was observed in the female subgroup between Arm A and Arms B and C (P = 0.09). No significant difference was detected for the various pain assessment procedures, functional criteria or quality‐of‐life criteria.ConclusionsCorticosteroids provide no additional therapeutic benefits compared with local anaesthetic and should therefore no longer be used.Tweetable abstractSteroid infiltrations do not improve the results of local anaesthetic infiltrations in pudendal neuralgia.

Spinal cord stimulation of the conus medullaris is a safe and effective technique for long-term treatment of refractory pudendal neuralgia. Routine use of this technique, which has never been previously reported in the literature in this type of patient, must now be validated by a larger scale study.

In day-to-day clinical practice management of PHN, treatment with the 5% lidocaine medicated plaster permitted a significant quantitative reduction in concomitant treatments for neuropathic pain in the overall efficacy population. In the subgroup aged ≥70 years, the quantitative reduction was non-significant. However, in both populations, 5% lidocaine medicated plaster reduced use of TCAs and step 3 analgesics. An improved polymedication status and good tolerability in this likely multimorbid age group indicate that the plaster is a new therapeutic alternative for patients suffering from PHN in France.

Background Since the development and publication of diagnostic criteria for pudendal nerve entrapment (PNE) syndrome in 2008, no comprehensive work has been published on the clinical knowledge in the management of this condition. The aim of this work was to develop recommendations on the diagnosis and the management of PNE. Methods The methodology of this study was based on French High Authority for Health Method for the development of good practice and the literature review was based on the PRISMA method. The selected articles have all been evaluated according to the American Society of Interventional Pain Physicians assessment grid. Results The results of the literature review and expert consensus are incorporated into 10 sections to describe diagnosis and management of PNE: (1) diagnosis of PNE, (2) patients advice and precautions, (3) drugs treatments, (4) physiotherapy, (5) transcutaneous electrostimulations (TENS), (6) psychotherapy, (7) injections, (8) surgery, (9) pulsed radiofrequency, and (10) Neuromodulation. The following major points should be noted: (i) the relevance of 4+1 Nantes criteria for diagnosis; (ii) the preference for initial monotherapy with tri‐tetracyclics or gabapentinoids; (iii) the lack of effect of opiates, (iv) the likely relevance (pending more controlled studies) of physiotherapy, TENS and cognitive behavioural therapy; (v) the incertitudes (lack of data) regarding corticoid injections, (vi) surgery is a long term effective treatment and (vii) radiofrequency needs a longer follow‐up to be currently proposed in this indication. Conclusion These recommendations should allow rational and homogeneous management of patients suffering from PNE. They should also allow to shorten the delays of management by directing the primary care. Significance Pudendal nerve entrapment (PNE) has only been known for about 20 years and its management is heterogeneous from one practitioner to another. This work offers a synthesis of the literature and international experts' opinions on the diagnosis and management of PNE.

(Abstracted from BJOG 2016; DOI: 10.1111/1471-0528.14222) Management of pudendal neuralgia (PN) is often not evidence based. The practice of adding corticosteroids to a nerve block in patients with PN is widespread and largely based on a few studies suggesting that corticosteroids may prolong the effect of a local anesthetic.
