IntroductionPudendal nerve and artery entrapment is an underdiagnosed pathology responsible of several urinary, sexual and anorectal complaints. The aim of our study was to evaluate safety and feasibility of laparoscopic transperitoneal pudendal nerve and artery release in a large retrospective cohort of patients with pudendal nerve entrapment syndrome with both a short and long-term follow-up. Technical details and outcomes are also reported.MethodsA series of 235 patients with pudendal syndrome underwent laparoscopic transperitoneal pudendal canal release between June 2015 and February 2020. Operative data were recorded prospectively for all patients. A complete history, pain visual analog scale (VAS) for perineodynia, and three scores evaluating the main symptoms (USP, IIEF-5, PAC-SYM) were obtained before and at least 24 months after surgery for 32 patients only. Post-operative complications were also evaluated using Clavien-Dindo classification at regular interval.ResultsThe mean operating time per side was 33.9 ± 6.8 min and the average hospital stay was 1.9 ± 0.3 days. Blood loss was 20 cc ± 10 cc with no patients needing transfusion. The only significant per-operative complication was hemorrhage (600 ml) in one patient induced by a pudendal artery laceration, successfully treated by laparoscopic suturing. Post-operative complications were noted in 18.7% of patients with no serious Clavien-Dindo complications. Perineodynia VAS dropped from 6.8 ± 0.9 to 2.2 ± 1.8 after surgery (p < 0.001). Mean IIEF-5 scores significantly improved one month after the surgery (15.2 vs 19.3, p = 0.036). Mean USP scores significantly improved for the dysuria domain (4.2 vs 1.6, p = 0.021) but not for stress urinary incontinence (3.9 vs 4.1, p = 0.082) or overactive bladder symptoms (14.1 vs 13.8, p = 0.079). Mean PAC-SYM scores significantly improved after the procedure (1.8 vs 1.1, p < 0.001).ConclusionA complete laparoscopic pudendal nerve and artery release, from the sciatic spine through the Alcock’s canal, is a fast and safe surgery with promising functional results. A large prospective trial is needed to validate such an approach.

Erectile dysfunction (ED) is increasingly becoming more common in young healthy males and is attributed mainly to psychogenic causes in these patients. Recent studies have reported that ED could be secondary to pudendal nerve or artery entrapment. This perspective assessed the efficacy of laparoscopic pudendal nerve and artery decompression in young patients suffering from refractory ED, associated to a pudendal nerve entrapment syndrome. After excluding patients with psychological ED and venous leakage, five young male patients with a history of both ED and pudendal nerve entrapment syndrome diagnosed based on the Nantes criteria were recruited. Pudendal nerve and artery release was performed using a laparoscopic transperitoneal approach. International Index for Erectile Function (IIEF-5) and erectile hardness score (EHS) improved significantly in all patients, 3 months after surgery. Pudendal nerve and artery entrapment could be therefore a reversible cause of ED in young healthy males, and its treatment by laparoscopic pudendal nerve and artery decompression seems to be safe and effective.

Ejaculatory dysfunction is one of the most common complaints of patients with sexual disorders. While it encompasses several ejaculatory disorders, weak ejaculation is seldom described in the literature. Since the pudendal nerve is the main nerve of ejaculation, we aim to hypothesize that pudendal nerve entrapment could be a cause of weak ejaculation, and that pudendal nerve release could contribute to the improvement of the ejaculatory stream. We presented two cases suffering from a weak ejaculatory stream and sensation of incomplete semen emptying, accompanied with clinical features of pudendal nerve entrapment. Both cases improved after pudendal nerve block and then laparoscopic transperitoneal pudendal release, with a sustained amelioration of the ejaculatory stream after 3 weeks of surgery. Pudendal canal entrapment is therefore a potentially curable cause for weak ejaculation.

Key Words: erectile dysfunction pudendal nerve entrapment laparoscopic surgery CASE PRESENTATION A 32-year-old Caucasian man with no previous remarkable medical history presented to the hospital with a complaint of erectile dysfunction (ED) not responsive to medical therapy [phosphodiesterase type 5 (PDE-5) inhibitors for the last 3 years], and concomitant poor orgasmic sensation. Pudendal nerve (PN) infiltration, under computed tomography (CT) guidance, led to a temporary relief of symptoms. Since pudendal compression was the suspected etiology causing these symptoms, and in accordance to the patient's wish, right PN and artery decompression was performed through a laparoscopic approach. [...]as the main concerns about the open surgical techniques described to treat PNE (transperineal, transgluteal, and via the ischiorectal fossa) are their invasiveness, difficultly of access and limited visibility, over the last years minimally invasive surgery has been proposed to overcome these limitations [7, 8, 9].

The aim of this article is to report the effectiveness of laparoscopic decompression of pudendal artery (PA) and nerve for erectile dysfunction (ED) restoration. A 32-year-old man presented with a long-term complaint of ED not responsive to medical therapy. Endocrine screening and neurological evaluation did not show any abnormalities. Color Doppler ultrasound revealed the absence of blood flow in the right PA. After failure of conservative treatments and in accordance to the patient's desire, laparoscopic pudendal artery decompression was performed. The patient reported significant amelioration of ED one month after surgery. At 8-months follow-up, Doppler ultrasound showed complete revascularization of the right PA.

Pudendal nerve (PN) entrapment is one of the most misunderstood and underdiagnosed medical conditions. It is recognized as a cause of chronic pelvic pain syndrome. However, due to the pudendal nerve's mixed composition and complex anatomy, the presenting symptoms are varied and go beyond pain, depending on the entrapment's nature, location and duration. We report a unique case of a young patient presenting with a urethral leak refractory to antibiotics. Patient evaluation highlighted findings suspicious of pudendal nerve entrapment. The patient was submitted to a laparoscopic transperitoneal PN neurolysis, resulting in major symptoms improvement.

Background: Amyloidosis is a tissue protein deposition. Urethral amyloidosis is rare. Clinical presentation includes hematuria, obstructive urinary symptoms, urethritis-like symptoms, urethral discharge, or a palpable penile/urethral mass. The diagnosis is made by urethro-cystoscopy and biopsy. Case Presentation: We report the case of a 38-year-old man with a medical history of recurrent urinary tract infections, urethral discharge, and a palpable bulbar urethral mass. Urethral biopsies confirmed the urethral amyloidosis. The treatment was endoscopic urethral dilatation. Conclusion: Urethral amyloidosis is a rare condition and a challenging diagnosis. Urethroscopy is the best method for diagnosis. Biopsies should be done to exclude malignancy.

Purpose To evaluate peri- and postoperative morbidity, and long-term oncologic and functional results of our laparoscopic radical cystectomy (LRC) technique, comparing it with our standard open approach. Methods Between 2000 and 2010, 54 patients underwent LRC for urothelial cell carcinoma of the bladder in two academic hospitals. The procedures were performed by two surgeons. Patients were matched 1:1 with patients who underwent open RC in the same years by the same surgical team. Differences in peri- and postoperative complications across the two groups were assessed using Wilcoxon’s rank-sum or χ 2 test. Kaplan–Meier curves, log-rank tests and Cox regression models were constructed to assess differences in recurrence-free survival on long-term follow-up between the two groups. Results Laparoscopic radical cystectomy was significantly associated with lower blood loss ( p  < 0.0001) and less frequent postoperative ileus ( p  = 0.03). Regarding more serious postoperative complications, no difference was found across the two cohorts. Median oncologic follow-up was 42 months (IQR 12–72 months) in the LRC cohort and 18 months (IQR 8–27 months) in patients undergoing open radical cystectomy (ORC). No statistically significant difference in recurrence-free survival was observed between the two groups (log rank p  = 0.677). On univariate Cox regression, the surgical approach used was not significantly associated with risk of recurrence. Conclusions We found that LRC is safe and associated with lower blood loss and decreased postoperative ileus compared with ORC. Moreover, on long-term oncologic follow-up, LRC appeared non-inferior to ORC with no significant difference in recurrence-free survival. Nonetheless, these results must be confirmed by larger series and stronger long-term follow-up data are needed.

We prospectively compared, within the same center and during the same period of time, the perioperative parameters as well as the oncological and functional results of both open retropubic (ORP) and laparoscopic radical prostatectomy (LRP). From September 1999 to September 2001, 162 patients with prostate cancer were treated with radical prostatectomy, 77 using an open retropubic technique, and 85 by the laparoscopic extraperitoneal approach. We prospectively recorded pre-, per- and postoperative parameters and complications, and evaluated the carcinological and functional results, comparing both approaches. There were no significant differences in the preoperative characteristics of the two groups. Mean operative time was statistically longer with LRP than with ORP (288 vs 168 min, P<0.0001) but median blood loss was decreased (400 vs 1,300 ml, P<0.0001). Major complications occurred in a similar number of cases (5% vs 2.4%, NS) while minor complications occurred more frequently with ORP (24.6 vs 11.8%, P=0.003). Pathological examination revealed a similar distribution of Gleason scores and stages in each group. Positive surgical margins in pT2 cases occurred in 7.8% of LRP and 7.3% of ORP. Continence rates (no pad and no leakage at all) were similar (83.9% in ORP vs 80.7% in LRP, NS). Potency rates were similar after 1 year in patients undergoing bilateral nerve sparing (55% in ORP vs 65% in LRP, NS). However, patients operated by LRP had more spontaneous erections. We conclude that this prospective, comparative study shows that LRP, when performed in specialized centers, gives oncological and functional results comparable to open surgery.
