Penile injection of aedile silicone: A dangerous shortcut.

INTRODUCTION: The size of penis can cause concern in patients, even if the organ is clinically normal. Additionally, the cost of phosphodiesterase 5 inhibitors (iPDE5) and long waiting lists to access penile prosthesis placement can lead patients to resort to non-medical and potentially dangerous alternatives. One of these dangerous alternatives is the injection of building silicone at the level of the subcutis of the penis or the corpora cavernosa causing the formation of a granuloma that increases the girth and consistency of the penis. CASE REPORT: The article describes the case of a 43-year-old patient who self-injected aedile silicone at the level of his penis in an attempt to achieve greater penile size and greater rigidity. The patient reported that he could not economically afford the iPDE5.The persistence of severe pain in the penis forced the patient to go to a urological examination. The patient subsequently underwent the penile granuloma exeresis procedure and skin reconstruction with scrotal flap. CONCLUSION: The pursuit of sexual well-being can lead some patients to rely on unconventional and potentially harmful techniques. The role of the andrologist and of the scientific society should be to dissuade the patient from using these dangerous methods and to provide valid alternatives accessible to the patient. The economic difficulty in purchasing drugs that facilitate erection or the long waiting lists for the placement of penile prostheses can favor dangerous methods such as penile injection of silicon. There is therefore a clear need to facilitate access to drugs and surgical techniques that favor the patient's sexual well-being.

Direct Vision, Transfascial (DVT) Approach to Submuscular Reservoir Placement in Patients Undergoing Multicomponent Penile Implant Surgery Following Prior Pelvic Surgery or Radiation Therapy.

BACKGROUND: Submuscular reservoir placement has fulfilled a critical need for patients desiring multicomponent penile implants following pelvic surgery and radiation therapy. Passage of the reservoir through the inguinal canal into the submuscular space is often challenging and carries the risk of the reservoir being placed unknowingly outside of the targeted space. AIM: To evaluate the safety and accuracy of a direct vision, transfascial (DVT) approach to submuscular reservoir placement. METHODS: We retrospectively reviewed outcomes for consecutive patients undergoing DVT submuscular reservoir placement abstracted from a large IRB-approved database at our institution. Postimplant cross-sectional imaging performed on many of these patients was used to ascertain the final location of the reservoir. OUTCOMES: Outcome measures included the perioperative and intermediate-term safety and complications of the procedure. Postimplant imaging ascertained the accuracy in providing patients with a submuscular reservoir. RESULTS: There were 107 DVT submuscular reservoirs placed in 100 consecutive patients. No intraoperative complications occurred, there were no postoperative rectus hematomas, and there were 4 (3.7%) postoperative infections. With a mean follow up of 17.5 +/- 20.5 months there was one reservoir herniation, one patient had autoinflation, and one patient required repositioning of a high riding pump. There were 4 mechanical malfunctions requiring revision at a median of 74 months (range: 69-108 months.) following implant placement. Of the 43 patients who underwent imaging: 34 (79%) reservoirs were accurately positioned, 5 (12%) were in the lateral abdominal wall, 1(2%) was in the retroperitoneum, and 3 (7%) were intraperitoneal. Intraperitoneal reservoirs occurred exclusively in postcystectomy patients. CLINICAL IMPLICATIONS: The DVT approach is technically safe, although a slightly higher than expected infection risk was noted. It provides accurate reservoir placement for the majority of imaged patients. Postcystectomy patients have a risk of insidious intraperitoneal reservoir placement. Preoperative counseling should mention this and postimplant imaging may be considered for some of these patients. Imaging may also helpful prior to future revision surgery in order to identify and remove insidious intraperitoneal reservoirs. STRENGTHS AND LIMITATIONS: We investigated 100 patients, almost half underwent cross sectional imaging. Weaknesses include the retrospective nature of this single-institutional study, which may not have similar outcomes at other centers. CONCLUSION: DVT submuscular reservoir placement is safe following pelvic surgery and radiation therapy. Despite careful and deliberate surgical technique imaging found that approximately 20% of reservoirs are not in their expected location. Intraperitoneal reservoirs are of concern, particularly in postcystectomy patients. Kava BR, Levine A, Hauser N, et al.

Effect of operative local anesthesia on postoperative pain outcomes of inflatable penile prosthesis: prospective comparison of two medications.

Few studies have examined the roles of dorsal penile nerve block (DPNB) and penile ring block (PRB) in surgery of inflatable penile prosthesis (IPP) placement. We sought to compare the postoperative pain outcomes of two different medications used in DPNB plus PRB. We thus carried out a prospective study of patients with erectile dysfunction who underwent "de novo" IPP placement between January 2013 and June 2013. Patients were divided to one of three groups: 1-DPNB plus PRB with bupivacaine injection; 2-DPNB plus PRB with ropivacaine injection and, 3-Control group without DPNB or PRB injection. Postoperative pain score and pain medication usage were recorded 2 h postoperatively, and every 24 h, for a week. The Visual Analog Scale (VAS) was used as pain scale measurement. A total of 131 patients were included in this study: 40 to bupivacaine, 47 to ropivacaine, and the rest were controls. Two hours postoperatively, mean VAS was significantly different (p < 0.0001) between medicated patients and the control group, however, no significant differences were observed between medication groups. Mean VAS was not significantly different among the groups from post-surgical day 2 thru 7. In conclusion, DPNB plus PRB during IPP provided effective analgesia in the immediate post-operative recovery.

In vitro assessment of antimicrobial properties of rifampin-coated Titan(®) Coloplast penile implants and comparison with Inhibizone(®).

INTRODUCTION: It is a common practice to soak Titan(®) Coloplast penile implants in antibiotic solution prior to implantation. Aim. The aim of this study is to identify an ideal solution for soaking the Titan(®) Coloplast penile implants prior to implantation. METHODS: Titan(®) strips were soaked in a different combination of antibiotics and the zone of inhibition was studied against Staphylococcus epidermidis and Escherichia coli. This zone of inhibition was compared against zone of inhibition produced by Inhibizone(®) -coated silicone strips. Zones of inhibitions were also compared for different components of Inhibizone(®) implant such as cylinder, tubing, connector, rear tip extender, and reservoir, and compared with similar components of Titan(®) Coloplast penile implants. MAIN OUTCOME MEASURES: The zone of inhibition against S. epidermidis and E. coli for Titan strips dipped in Rifampin and Gentamicin was compared against other antibiotics. The clinical significance of dipping Titan(®) -coated Coloplast implant in Rifampin and Gentamicin solution was determined. RESULTS: Rifampin 10mg/mL+gentamicin 1mg/mL (R10/G1) and rifampin 1mg/mL+gentamicin 1mg/mL (R1/G1) had excellent coverage against S. epidermidis and E. coli. The zone of inhibition (utilizing the Titan(®) coating) produced by both these solutions exceeds that produced by Inhibizone(®) by 40% to 56% for S. epidermidis and 33% for E. coli. Components of the American Medical System implant (tubing connectors and rear tip extenders) are not coated with antibiotics and had no zone of inhibition. CONCLUSION: Soaking Titan(®) -coated Coloplast implants in R10/G1 solution produces a zone of inhibition greater than that produced by Inhibizone(®) -coated penile implants. The clinical significance of this increased zone of inhibition can only be determined by a separate clinical study.

Outpatient penile implantation with the patient under a novel method of crural block.

Although local anaesthesia for penile implants has been substantially reported, its methodology, simplicity and reliability left room for improvement. We would like to report on an innovative penile crural block using local anaesthesia in patients who underwent penile implantation as outpatient surgery. From March 1987 to March 1991, a total of 21 organically impotent men, aged from 27 to 77 years, received penile prosthesis implantation. All these were performed under pudendal nerve block as an outpatient procedure. From August 1992 to January 2003 a proximal dorsal nerve block with peripenile infiltration and penile crural block was developed to replace the anaesthesia method of pudendal nerve blocks in 137 consecutive patients (aged from 35 to 83 years) undergoing penile implants. The anaesthetic effects and postoperative results with the crural block were very satisfactory. Common immediate side-effects included puncture of the vessels, subcutaneous ecchymosis, transient palpitations and dilation pain, but there were no significant late complications. In the group of pudendal nerve blockage, 42.9% patients (nine of 21) experienced severe aching pain over the perineum for 1-2 weeks postoperatively, whereas the newly developed method of crural block markedly reduced these adverse effects. This new anaesthetic method proved to be reliable, simple, and safe with fewer complications. It offers the advantages of less morbidity, preservation of patient's privacy, reduced adverse effects of anaesthesia, and a more-rapid return to activity with minimal complications.
