Optimizing collagenase Clostridium histolyticum therapy for Peyronie's disease using a novel approach with percutaneous needle tunnelling.

OBJECTIVES: To compare the efficacy and safety of a combined treatment of percutaneous needle tunnelling (PNT) and a modified collagenase Clostridium histolyticum (CCH) protocol (PNT/CCH) vs the modified protocol alone (CCH) in the treatment of Peyronie's disease (PD). PATIENTS AND METHODS: A prospective registry of patients treated with a modified CCH protocol was maintained between June 2014 and February 2018. The last 50 patients received PNT as an adjuvant therapy (PNT/CCH), and their data were compared with those of the other 94 patients treated previously (CCH). PNT involves the creation of multiple holes made percutaneously in the plaque before each injection. The modified protocol consisted of two collagenase injections, at 1-week intervals, followed by penile modelling. Patients used penile traction therapy, tadalafil and pentoxifylline for the next 2 months and were followed up for 6 months. The main outcome was improvement of curvature. Secondary outcomes were improvements in erectile function, PD symptoms, stretched penile length and satisfaction. RESULTS: Improvement in curvature was greater in patients in the PNT/CCH group than in the CCH group (mean ± sd 19.2 ± 6.1° vs 12.7 ± 5.0°; P < 0.001 [36.2 ± 12.5% vs 28.1 ± 14.5%; P = 0.001]). Compared with baseline, both interventions were associated with significant improvement in secondary outcomes. The main complications were ecchymosis, bruising and penile pain, with no significant differences between groups. CONCLUSIONS: Treatment of PD with CCH using our modified protocol in combination with PNT is safe and more effective than the modified protocol alone, with the potential for improved cost-effectiveness.

Surgical Technique for Complex Cases of Peyronie's Disease With Implantation of Penile Prosthesis, Multiple Corporeal Incisions, and Grafting With Collagen Fleece.

INTRODUCTION: Patients with Peyronie's disease (PD) and erectile dysfunction (ED) concomitant with shortening or other malformations benefit from prosthesis implantation and penile lengthening procedures. AIM: To evaluate the safety and efficacy of a multi-incisional technique with penile prosthesis implantation with multiple corporeal incisions and collagen grafting for the surgical management of complex cases of PD with ED and severe penile shortening. METHODS: From February 2015-May 2018, 43 consecutive patients with complex PD were treated using this technique. Implantation of a penile prosthesis (malleable or inflatable [IPP]) together with multiple relaxing tunica albuginea incisions and grafting with a self-adhesive collagen-fibrin fleece (TachoSil, Baxter Healthcare) was performed in all patients by a single surgeon (J.I.M.S.). MAIN OUTCOME MEASURE: Penile length and curvature correction, operative time, and incidence of postoperative complications were recorded as outcome measures. Functional outcomes were measured with questionnaires (International Index of Erectile Function-5, Erection Hardness Score, modified Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire, PD Questionnaire) before and 3 and 6 months after surgery. RESULTS: With a median follow-up of 21 months (range 10-31), mean postsurgical penile lengthening was 2.5 (range 1-5) cm, with an improvement in the Bother domain of the PD Questionnaire of 4.4 (range 2-5) points. The average operative time was 86.7 and 71.6 minutes for the IPP and malleable penile prosthesis procedure, respectively. No glans ischemia was recorded; however, 1 IPP infection and 1 delayed distal corporeal erosion were recorded. Hematoma or bruising was observed in 23.2% of patients. The modified Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire was completed by 39 (90.7%) patients. Overall, 89.7% would recommend this surgery. Patient satisfaction with straightness and length was 94.9% and 82.1%, respectively. CLINICAL IMPLICATIONS: The described technique helps restoration of penile length and erectile function in patients with complex PD. STRENGTHS & LIMITATIONS: The strength of the study is that it offers a simple, easy-to-apply technique for surgeons to correct shortening and other malformations in patients with ED and complex PD. The study is limited by the small number of patients, the short follow-up period and the performance of the technique by a single high-volume implanter. CONCLUSION: The implantation of a penile prosthesis (malleable or inflatable) together with multiple incisions of the plaque/tunica albuginea and grafting with a collagen fleece is a safe and efficient treatment for patients with complex PD in addition to ED and significant shortening.

The performance of vasectomy in an urban municipality. Practical considerations for follow-up.

OBJECTIVES: To establish an adequate follow-up protocol based on time to azoospermia achievement after vasectomy. Also, to review the rate of complications in our setting. METHODS: Retrospective analysis of 391 men who underwent vasectomy. Follow-up was performed by means of semen analysis 6 months after surgery, and then every 3 months until azoospermia was achieved. Data of visits to the emergency unit at our centre were obtained within the first 30 postoperative days. RESULTS: During follow-up 567 semen analysis were performed. From 391 vasectomy interventions, 275 had at least one semen sample available and valid for processing. After the first 6 months from surgery, 41.1%men still presented nonmotile rare sperm in semen analysis, 9.7% after 9 months, and 4.7% after 12 months. If semen analysis was postponed from 6 to 9 months after surgery, a total yearly saving of 6,153.23 Euro would be observed in our setting, but with the drawback of delaying the diagnosis of azoospermia in nearly 60% of men. Overall complication rate was 3.1%(only one man required hospital admittance and reintervention). No statistical difference was observed in operative time with regard to the presence or absence of urological complications. CONCLUSIONS: The percentage of men not achieving azoospermia 6 months after surgery is notorious. Vasectomy practice in our setting seems to be reliable and safe, with a limited rate of complications.
