Concentric needle EMG was done at rest and during voluntary contraction on both sides of the external anal sphincter and on each bulbocavernosus muscle. The skin rolling test was improved as much as the perineal sensibility and the Alcock’s canal pain, thus showing its relevant link with the PCS. The frequency of the three clinical signs was significantly reduced. Shafik described many clinical signs of the PCS [ 5 , 29 , 30 ]. Anatomic basis of chronic perineal pain: Citations Publications citing this paper. An impressive clinical response followed. The statistical comparison was done between the patient’s group before “cases group” and after the operation, and the “controls group” of 82 women average age:

Benson JT, Griffis K. Clinical significance of sacral and pudendal nerve anatomy. If this study is confirmed by others, the treatment of the neuropathy should be done before any trial of neuromodulation. Implications in perineal pain syndromes. If the change observed was in the opposite direction the patient was considered “worsened”. The most specific sign was the “Painful skin rolling test” and the most sensitive was the “Painful Alcock’s canal”. Anatomical basis of chronic pelvic pain syndrome: Just inferior to the ischial spine, the nerve gives its first branch, the dorsal nerve of the penis [ 4 ] or the clitoridal nerve.

Before discussing the results of surgery, the first important issue is about the interest of a bilateral decompression. The effect of surgery was estimated by the patient using one of the following proposals: Implications in perineal pain syndromes.

Received Mar 20; Accepted Oct This syndrome is induced by the compression or the stretching of the pudendal nerve in the Alcock’s canal. Therefore, these values were considered independent maximum number of analysed cases: This was a small, uncontrolled study with no follow-up evaluations. Current treatments for PN entails behavioral modifications, pharmacotherapies e.


The frequency of the 3 clinical signs was significantly reduced.

Pudendal nerve decompression in perineology: a case series.

The objective evaluation of PND was done nervs two neurophysiological tests and the clinical examination. Over a 4-year period, the diagnosis of PN was confirmed by electrophysiological investigations in subjects.

Bucarest Roumania; Neuromodulation for voiding dysfunction and fecal incontinence: The clinical signs are not used to decide if a subject belongs to the controls perineologu cases group. The degree of pain and pain impact were evaluated pre- and post-operatively using the VAS and the Impact of Symptoms and Quality of Life. Table 9 The three clinical signs in the diagnosis of pudendal canal syndrome.

In this study, we evaluated the decojpression of the PCS in an outpatient perineology clinic. Table 11 Evaluation of different combinations of the three clinical signs of pudendal canal syndrome. J Neurol Neurosurg Psychiatry.

For anal incontinence, a four levels ordinal scale was used: In the long term the continence is probably maintained with the help of the fibrous tissue located between the two edges of the ruptured muscle which acts like a bridge and therefore enables the sphincter to be efficient during many years.

Pudsndal negative 0,81 0,57 0,32 0,92 5,82 2,16 — 15,66 32 The most sensible test is the “Painful Alcock’s canal” and the most specific is the “Skin rolling test”. The objective of perineology is to treat each defect of the perineum with the right procedure [ 1 – 3 ]. Sensibility was tested with a needle comparing the left and the right sides of the vulva and of the skin 2 cm lateral to the anus.


Pudendal Nerve Decompression

Three months after surgery, 4 patients were totally relieved, and 3 were only partially improved. Surgical procedure as described by Shafik in [ 5 ]. This nerve gives a bulbocavernosus branch and finally divides into a sphincteric branch innervation of the urethra and a branch which innervates the skin of the anterior perineum [ 9 ].

Normative values of skin temperature and thermal sensory thresholds in the pudendal nerve territory.

The three clinical signs of PCS seem to be efficient to suspect this diagnosis. Benson JT, Griffis K. This anatomy is still controversial.

Methods In this retrospective analysis, the studied sample comprised 74 female patients who underwent peruneology bilateral PND between and Anal incontinence can be cured by pudendal nerve decompression alone even in the presence of a clear disruption of the anal sphincter on anal ultrasound.

In a previous study, 3 of the 7 patients pudendaal a stress urinary incontinence were cured by bilateral pudendal nerve decompression alone [ 3637 ]. Albert Neurourology and urodynamics Citation Statistics 78 Citations 0 5 10 15 ’08 ’11 ’14 ‘ Using the three signs altogether, the most sensible combination is “At least 1 positive versus All negative” and the most specific combination is the “All positive versus All negative”.

Caudally, the pudendal nerve enters a small space “clamp” between the sacro-spinal and sacro-tuberous ligaments very near the ischial spine.

One patient still presents with a mild seriess clitoridal pain and a worsening of anal incontinence.
