Surgical outcomes after collagenase Clostridium histolyticum failure in patients with Peyronie’s disease in a multicenter clinical study.

In the present study we aimed to investigate the surgical outcomes of patients with persistent penile curvature (PC) after Collagenase Clostridium histolyticum (CCH) intraplaque injections. Data from 90 patients with persistent PC after CCH in a multicentre study from 6 andrological centres were retrospectively reviewed. Three standardized surgical techniques were performed. Group 1: plaque incision grafting (PIG) with penile prosthesis implant (PPI); Group 2: PIG without PPI; Group 3: Nesbit technique. Hospital stay, operative time, postoperative complications and PC persistency/recurrence (> 20°) were evaluated. Overall satisfaction and functional outcomes were assessed through International Index of Erectile Function-Erectile Function (IIEF-EF), Peyronie’s Disease Questionnaire (PDQ), Female Sexual Function Index (FSFI) administered pre and 3 months postoperatively. Of all, 25 (27.8%) patients received grafting procedure + PPI (Group 1), 18 (20.0%) patients belonged to Group 2, and 47 (52.2%) to Group 3. Bovine pericardium graft and collagen fleece have been used in in 22 (51.2%) and 21 (48.8%) patients, respectively. Median penile length after surgery was 13.0 cm (IQR 12.0–15.0). After surgery, Group 1 showed higher increase in penile length after surgery and better improvements in terms of PDQ-PS. In contrast, both IIEF-EF and FSFI scores did not differ among groups. Overall, 86 (95.6%) did not report any complication. 4 (4.4%) patients had PC recurrence; of those, 2 (8.0%), 1 (5.6%) and 1 (2.1%) cases were observed in Group 1, Group 2 and Group 3, respectively. In case of persistent PC after CCH, surgical correction by grafting with or without concomitant PPI or Nesbit technique emerged as a technically feasible, effective and safe procedure, with no significant postoperative complications.post-print1243 K

Perineal and robot-assisted vesico-urethral reconstruction for anastomotic strictures after RP

Vesico-urethral anastomotic stricture (VUAS) following radical prostatectomy is a rare clinical condition in the robot-assisted procedure era, due to the improved magnification of the surgical field and the perfect knowledge of the anatomic structures deputed to maintaining the mechanisms for urinary continence. Improvements in surgical technique such as muco-mucosal apposition, tension-free anastomosis, water-tight vesico-urethral suture, have been recognized as significant contributors to precise vesico-urethral reconstruction. Conversely, excessive intraoperative blood loss, urinary extravasation and previous history of trans-urethral prostatectomy have been commonly cited as predisposing factors for the development of postoperative scars. Terminology used in the definition of VUAS distinguishes the condition from bladder neck contracture (BNC) and identifies the exact site of the contracture/stenosis/stricture. The majority of cases involves the bladder neck and bulbo-membranous urethra mainly in patients who received radical prostatectomy plus adjuvant radiotherapy. Diagnosis of VUAS is mainly based on symptoms and retrograde urethro-cystogram imaging to identify whether or not the sphincter mechanism is involved and the length of the strictured segment, although delineation of the precise anatomy is often complex. Stricture length is a significant factor for prognosis and correlates with probability of recurrence after reparative surgeries such as urethral dilation, trans-urethral scar incision or resection and perineal urethral buccal mucosa repair. Results obtained via different surgical techniques are amply described, with the hindrance of VUAS and BNC often not being properly distinguished in the reported series of patients treated. Notwithstanding, a 0 to 69% success rate has been reported for patients with bladder neck stricture after urethral dilation and/or cold-knife incision and/or holmium laser incision and/or trans urethral resection, while a 60 to 93% success rate was obtained for patients treated via an abdominal and/or perineal approach. Repair of a long-length urethral stricture often implies the complete loss of urinary continence, whilst it does not appear to have significant impact on sexual potency if previously preserved. The risk of developing VUAS/BNC as a complication after radical prostatectomy falls from 30% of patients treated by Retropubic Radical Prostatectomy (RRP) to less than 5% of patients who received Robotic Assisted Radical Prostatectomy (RARP). Subjects with a histological diagnosis of T3 cancer, positive surgical margins and/or Gleason score >7 and treated by RARP who required early adjuvant radiotherapy, reported an overall 8.4% rate of VUAS. Lavollè et al. treated six patients with anastomotic stricture who had previously undergone radical prostatectomy by extraperitoneal robot-assisted vesico-urethral reconstruction obtaining a 50% success rate. Dinerman et al. presented a case report on a patient with long-length post prostatectomy vesico-urethral stricture by combining robotic-abdominal and open-perineal surgical procedure. The combined abdomino-perineal approach allows to provide “complete” scar removal and a new vesico-urethral anastomosis at a lower risk of developing subsequent recurrences of the stricture also in patients with long-length strictures. An extensive dissection of the bladder neck and bulbo-membranous urethra does imply the complete loss of urinary continence, that can however be recovered through subsequent or concomitant artificial sphincter implant. This novel combined technique was adopted on a series of three patients of whom two previously treated by RARP and one by RRP

The role of diallyl thiosulfinate associated with nuciferine and diosgenin in the treatment of premature ejaculation: a pilot study

Objective: To assess the efficacy and safety of an association of diallyl thiosulfinate with nuciferine and diosgenin in the treatment of a group of patients suffering from premature ejaculation (PE), primary or secondary to erectile dysfunction (ED). Materials and methods: From July 2015 to October 2016, 143 patients (mean age 25.3; range 18-39) affected by PE completed the study and were finally analyzed in this phase I study. All patients, after clinical assessment and laboratory evaluation were asked to take an association of diallyl thiosulfinate with nuciferine and diosgenin as oral tablet, once a day, on alternate days, for three months. At the baseline and after three months of treatment, each patient was asked to complete the following questionnaires: International Index of Erectile Function (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT), Male Sexual Health Questionnaire (MSHQ). Results: A statistical significant improvement in terms of erectile function, comparing the IIEF-5 value at baseline and follow-up visit was found (respectively IIEF-5: 8.7 vs 14.01; p < 0.001). Moreover, at follow-up visit, 97/143 men (67.8%) referred a subjective improvement of the erection quality and a better control of the ejaculation (PROs). The IELT improved too between the baseline evaluation and the follow-up visit (p < 0.001). Conclusion: In conclusion, our study, even if supported by preliminary results, showed how Diallyl Thiosulfinate, Nuciferine and Diosgenin is able to improve the control of ejaculation in patients suffering from PE, primary or secondary to ED without any significant adverse effects

The Role of a Multidisciplinary Approach in Gender Affirmation Surgery: What to Expect and Where Are We Currently?

Gender Affirmation Surgeries (GASs), erstwhile called Sex Reassignment Surgeries (SRSs), may be necessary for transgender individuals to change their bodily sexual characteristics and thereby affirm their gender identity. GASs encompass all medically necessary interventions to relieve gender dysphoria and should be available to patients who wish to, and who meet the surgical criteria of the World Professional Association for Transgender Health (WPATH) and Standards of Care (SOC). The comprehensive clinical assessment involves many health specialists, including general practitioners, psychologists, psychiatrists, speech therapists, endocrinologists, surgeons, anesthesiologists, nurses, and other healthcare professionals. To define the patients’ complex care needs and their objectives, high-volume specialized centers, accredited training programs, skilled surgeons and health professionals specializing in transgender care within a multidisciplinary team are essential. Currently, the most prominent challenges are related to ethical issues such as the treatment of underage individuals, fertility, parenting and the potential for regret after GAS. Finally, although GAS has been practiced for more than half a century, data on long-term follow-up represents a further topic for investigation

A Novel Penile Splint as Early Traction Therapy After Grafting Techniques for Peyronie's Disease.

Background Some studies showed encouraging results on the efficacy and safety of penile traction therapy after Peyronie's disease (PD) surgery. The early traction therapy (ETT) could be an effective and safe approach to minimize penile shortening in patients undergoing PD surgery. Aim To evaluate the feasibility, efficacy, and safety of a novel penile splint as ETT in patients with PD undergoing grafting techniques. Methods Patients with PD underwent plaque incision and grafting technique; at the end of the procedure, a novel penile splint (ETT) was applied to all patient. The device consisted of 2 10CH intubating stylets, self-adapted to each patient, that kept the penis stretched with the aid of non-absorbable sutures. The total expense for the materials needed to build each penile splint was less than 15 euros. This active traction was maintained for 1–3 weeks; then, we removed the stitches leaving the device on-site for a passive traction. Within 3–4 weeks from surgery, the penile splint was replaced by a standard penile traction device. Outcomes The main outcomes evaluated at 6 months included stretched penile length (SPL), penile curvature, International Index of Erectile Function-erectile function (IIEF-EF) domain, patient satisfaction, and time to first satisfactory sexual intercourse. Results A total of 46 patients were enrolled. The median preoperative IIEF-EF, penile curvature, and SPL were 27 points, 70°, and 13 cm, respectively. The median follow-up was 15 months. The median postoperative IIEF-EF was 25 points (P < .001). The median residual penile curvature was 10° (P < .001). The median postoperative SPL was 13 cm (P = .269). 8 patients (17.4%) lost 1 cm of SPL; no shortening greater than 1 cm was recorded. The median time to first satisfactory sexual intercourse and patient satisfaction score was 6 weeks and 9 points, respectively. Clinical Implications Our results could pave the way for a new line of research, which in turn could lead to an improvement in the postoperative management of the patient undergoing surgery for PD. Strength & Limitations This is the first study evaluating the ETT after PD surgery. The main limitation of this study is the lack of a randomized control group. Other weaknesses are the small sample size and the short follow-up time. Conclusion Our novel penile splint is inexpensive, easy to assemble, and adaptable to the patient. ETT using this novel device, followed by standard traction therapy, seems to be feasible, effective, and safe.pre-print449 K
