  • Pudendal nerve entrapment (PNE) syndrome refers to the condition in which the pudendal nerve is entrapped or compressed. Reported cases of PNE associated with ganglion cysts are rare. Deep gluteal syndrome (DGS) is defined as compression of the sciatic or pudendal nerve due to a non-discogenic pelvic lesion. We report a case of PNE caused by compression from ganglion cysts and treated with steroid injection; we discuss this case in the context of DGS. A 77-year-old woman presented with a 3-month history of tingling and burning sensations in the left buttock and perineal area. Ultrasonography showed ganglion cystic lesions at the subgluteal space. Magnetic resonance imaging revealed cystic lesions along the pudendal nerve from below the piriformis to the Alcock's canal and a full-thickness tear of the proximal hamstring tendon. Aspiration of the cysts did not yield any material. We then injected steroid into the cysts, which resolved her symptoms. Steroid injection into a ganglion cyst should be considered as a treatment option for PNE caused by ganglion cysts.

  • An artificial sphincter implanted in the bulbous urethra to treat severe postprostatectomy urinary incontinence is effective, but embedding-associated complications can occur. We assessed the feasibility, efficacy, and safety of urethral graciloplasty cross-innervated by the pudendal nerve. A simulation surgery on three male fresh cadavers was performed. Both ends of the gracilis muscle were isolated only on its vascular pedicle with proximal end of the obturator nerve severed and transferred to the perineum. We examined whether the gracilis muscle could be wrapped around the bulbous urethra and whether the obturator nerve was long enough to suture with the pudendal nerve. In addition, surgery was performed on a 71-year-old male patient with severe urinary incontinence. The postoperative 12-month outcomes were assessed using a 24-hour pad test and urodynamic study. In all cadaveric simulations, the gracilis muscles could be wrapped around the bulbous urethra in a γ-loop configuration. The length of the obturator nerve was sufficient for neurorrhaphy with the pudendal nerve. In the clinical case, the postoperative course was uneventful. The mean maximum urethral closure pressure and functional profile length increased from 40.7 to 70 cm H2O and from 40.1 to 45.3 mm, respectively. Although urinary incontinence was not completely cured, the patient was able to maintain urinary continence at night. Urethral graciloplasty cross-innervated by the pudendal nerve is effective in raising the urethral pressure and reducing urinary incontinence.

  • The alcoholic neuropathies developed in approximately 34% of chronic alcoholics and the sexual dysfunction had been experienced in 8-54% of male alcoholics(Schiavi 1990). The aims of this study were to identify the prevalence of subclinical polyneuropathies and sexual disorders in alcohol dependence, and to evaluate the association between them. The nerve conduction velocity(NCV), electromyography(EMG), and pudendal somatosensory evoked potentials(SEPs) were tested for the male alcoholics(N=34) and controls(N=17 for NCV & EMG, N=25 for pudendal SEPs). The pudendal SEPs were measured by the following procedures, in which we stimulated the dorsal nerve of penis attached by the ring electrode(stimulus intensity, three times of threshold : stimulus rate, 1-4.7Hz : stimulus duration, 0.1 or 0.2msec), and recorded at the scalp(active electrode, 2cm behind Cz : reference electrode, Fz). The NCV and EMG detected signs of peripheral neuropathies in 79.4% of alcoholics. Among the alcoholics, 64.7% were abnormal on the pudendal SEPs. Among the alcoholics who revealed abnormality on EMG and NCV, 81.4% were abnormal on the pudendal SEPs, in which 51.9% were not responded. The P1 latencies of pudendal SEPs on neuropathic alcoholics were significantly delayed(p<0.05) than non-neuropathic alcoholics. There was a relative correlation between peripheral neuropathies and sexual disorders in the alcoholics. The prevalence of subclinical neuropathies and sexual disorders seemed to be much higher in alcohol dependence than expectation, and these two problems were relatively correlated, and our results suggested that the peripheral polyneuropathies were one of the prerequisites of sexual disorders.

  • Sciatic nerve (SN) is the thickest and longest nerve of the body. Deviations from the normal anatomical origin and level of bifurcation of SN have been frequently reported. In the present case, we are presenting a unique scenario of origin of terminal branches of the SN-tibial nerve (TN) and common peroneal nerve (CPN) in the pelvic region itself from divisions arising directly from the lumbosacral plexus. This variation was associated with origin of posterior femoral cutaneous nerve from the superior division of CPN with anomalous communicating branches between pudendal nerve and TN. The unique characteristics of the present case are the presence of 'pseudoganglion' found on the inferior division of TN. The present case stands out as the first of its kind to mention such pseudoganglion. Knowledge of some unusual findings like presence of pseudoganglion and intercommunications between nerves have clinical implications in anesthesiology, neurology, sports medicine, and surgery.

  • Various flaps are used to reconstruct skin and soft tissue defects of the vulva following resection of malignancies. Whenever possible, reconstruction using local flaps is the standard treatment. Here, we describe vulvar defect reconstruction using keystone flaps. Standard keystone flaps are based on randomly located vascular perforators. However, we designed a keystone flap that includes perforators of three named arteries (the anterior labial artery of the external pudendal artery, cutaneous branches of the obturator artery, and posterior labial artery of the internal pudendal artery) and the pudendal nerve, which accompanies the internal pudendal artery. Four patients with squamous cell carcinoma and extramammary Paget's disease of the vulva underwent radical vulvectomy and keystone flaps including perforators of three arteries. Depending on the morphology of the defects, keystone flaps were used with different designs. For elliptical and unilateral vulvar defects, a standard keystone flap was designed, and for defects on both sides of the vulva, a double opposing keystone flap was used. For oval defects, the omega variant keystone flap was designed, and when the morphology of the defect needed rotation of the flap, a rotational keystone flap was designed. All the patients showed good function and sensation, with an acceptable cosmetic appearance.

  • Purpose: Mayer-Rokitansky-Kuster syndrome (MRK) is second common cause of primary amenorrhea. It is a syndrome of vaginal aplasia and Mullerian duct anomaly. Vaginal aplasia varies from agenesis of whole vagina to aplasia of upper 2/3. For reconstructing vagina, various methods are introduced. Gracilis myocutaneous flap was the first attempt in that the flap is used in vaginal reconstruction. Various flap-based vaginal reconstruction methods have been introduced. Modified Singapore flap (pedicled neurovascular pudendal thigh fasciocutaneous flap) is one of those methods that used posterior labial artery as pedicle, and pudendal nerve branch as sensory root. As its donor lies on inguinal crease that is easily hidden and there are benefits on sexual intercourse by early sensory recovery, authors think that modified Singapore flap is effective for young MRK syndrome patients. Methods: Eight patients underwent surgery between 2008 and 2010. The flap was designed on both groin area with external pudendal artery branch as a pedicle. All flaps were fixated in pelvic cavity with absorbable suture, and additional compression on neovaginal wall was supplied by polyvinyl alcohol sponge ($Merocel^{(R)}$). Results: All patients were successfully reconstructed without flap related complications such as congestion or partial flap loss. The average size of the flap (each side) was 69.34 $cm^2$. Polyvinyl alcohol sponge ($Merocel^{(R)}$) was inserted into neovagina for 5 days on every patient. One case of rectal laceration was occurred while making pelvic pocket by OBGY team. Other complications such as lumen narrowing, wound contracture or vaginal prolapsed were not reported during 8 months of follow up. Conclusion: Modified Singapore flap is a sensate fasciocutaneous flap that is thinner than other myocutaneous flap such as VRAM, and more durable over skin graft. Therefore this is a good choice for vaginal reconstruction in MRK syndrome. And known complications of Modified Singapore flap could be reduced with careful procedure and mild compression techniques.

  • Onuf 핵이란 척수 앞회색질뿔에 위치하는 운동핵으로 음부신경을 통해 방광과 항문괄약근을 조절하는 운동핵의 하나이다. Onuf핵은 앞회색질뿔내 다른 운동신경핵과는 달리 회색질척수염과 같은 병적인 상황에서도 상당기간 손상되지 않고 기능을 유지하며, 퇴행성변화의 정도가 미약한데 정확한 원인에 관해서는 논란의 여지가 많다. 본 연구는 흰쥐 척수회색질내 바깥요도조임근을 신경지배하는 Onuf핵의 위치를 HRP 추적법으로 확인하였으며, 이들 신경핵내 운동신경세포와 연접해 있는 zinc함유(ZEN)신경종말의 미세구조를 zinc selenium조직화학법(AMG)으로 염색하여 관찰하였다. HRP 추적법의 결과로는, Onuf핵은 랫드 척수회색질앞뿔의 내측에서 가지돌기의 무리와 거의 맞닿고 있었으며, 모양은 대개 구형 또는 난원형을 띠었다. 이들 신경핵내 운동신경세포의 세포체의 크기는 다른 운동핵의 신경세포보다 다소 작았다. 한편 AMG로 염색한 표본에서는 Onuf핵에 분포하는 ZEN신경종말은 다른 운동핵의 ZEN 신경종말과 비교하여 매우 높은 밀집도를 보였으나, 크기 면에서도 상대적으로 작았다. 미세구조 관찰로는 Onuf 핵내 ZEN신경종말은 운동핵의 세포체 및 가지돌기와 신경연접은 이루고 있었다. 이들 ZEN 신경종말은 주로 납작한 연접소포를 함유하였으며, 대칭적인 신경연접구조를 이루고 있었다.

  • 요실금의 유병률은 전세계적으로 남성에서 3~11%, 여성에서 25~45%에 달할 정도로 매우 흔한 질환이며, 향후 고령화 진행에 따라 요실금은 더욱 증가할 것으로 예상된다. 요실금은 환자와 가족의 삶의 질을 현저히 떨어뜨리고, 우울감, 스트레스, 자존감 저하를 유발한다. 기존에 정신과 질환을 앓고있는 환자에서 요실금이 새로 발생할 때 정신과적 증상 악화, 치료 순응도 저하, 치료 효과 반감 등에 영향을 줄 수 있어 유의가 필요하다. 요실금은 대부분 방광 저장능력의 결함으로 일과성, 만성 요실금으로 구분된다. 일과성 요실금은 가역적인 요실금으로 delirium, infection, atrophic urethritis/vaginitis, psychological disorders, pharmaceuticals, excess urine output, restricted mobility, stool impaction (DIAPPERS)이 대표적인 원인이다. 만성 요실금은 복압성, 절박, 혼합, 일류성 또는 범람, 기능성, 그리고 지속성 요실금으로 구분된다. 약물 유발 요실금은 일과성 요실금의 한 종류로 임상에서 흔히 볼 수 있으며 여러 가지 정신과 약제에 의해서도 유발될 수 있다. 항정신병 약제가 가장 대표적으로 알려졌으며, 비정형 항정신병 약제의 알파 아드레날린성 차단효과로 인한 요도 괄약근 근긴장도 저하, 항콜린성작용에 의한 요폐, 세로토닌 길항 효과로 인한 pudendal nerve 반사 저하, 심한 진정효과, 약물유발 당뇨, 경련 등 여러가지 메커니즘이 작용하는 것으로 추정된다. 리튬은 요실금과 관련된 증례가 보고된 사례는 미미하나 신성 요붕증으로 인한 일류성 요실금과 연관될 수 있고, 발프로산도 명확하지 않은 기전으로 야뇨증을 유발할 수 있다. 항우울제의 경우 SSRI는 세로토닌 경로와 배뇨근 활성에 영향을 줌으로써, SNRI와 TCA는 요저류를 유발함으로써 요실금을 일으킬 수 있다. 부프로피온과 멀타자핀도 드물지만 요실금 사례가 보고된 바 있다. 벤조디아제핀의 경우 방광의 근이완으로 요저류와 요실금을 모두 유발할 수 있으며 항치매제로 쓰이는 아세틸콜린 분해효소 억제제는 말초의 아세틸콜린을 증가시켜 요실금을 유발한다. 이렇듯 요실금은 여러 정신과 약제로 인하여 발생될 수 있으므로, 요로 증상을 면밀히 확인하여 약물 선택과 조절에 주의해야 하며, 요실금이 약물로 인한 것임이 밝혀졌을 경우 원인 약물의 중단, 감량 또는 분복 변경이 필요하며 약물치료로는 desmopressin, oxybutynin, trihexyphenidyl, amitriptyline을 추가해볼 수 있다.
