Lengthening strategies for Peyronie's disease

Scrotal approach for tunica expansion procedure (TEP) for penile girth and length restoration during penile prosthesis implantation in patients with penile angulation due to Peyronie's disease and erectile dysfunction: technique and outcomes

Peyronie's disease is often comorbid with erectile dysfunction and can cause significant penile shortening. We describe our modified tunica expansion procedure (TEP) technique of penile length preservation and girth enhancement with correction of penile angulation in patients with mild Peyronie's disease (<30 degree angulation, or hourglass deformity, no hinging) and erectile dysfunction presenting for inflatable penile prosthesis (IPP) surgery. A retrospective review of IPP placement from one high volume surgeon was performed. A total of 474 patients' charts from June 2017 to June 2021 were reviewed and those charts of patients undergoing modified TEP in the setting of Peyronie's disease were analyzed. Average increase in length and girth were measured and means with standard deviations calculated. The modified TEP is performed through a scrotal approach and involves complete eversion of the penis with dissection of Buck's fascia off the underlying tunica. Subsequently, staggered scorings of the underlying tunica are performed allowing for circumferential girth enhancement and length preservation. In men with Peyronie's disease, these scorings are preferentially concentrated on the side of the plaque to allow straightening without loss of length. A total of 32 patients with Peyronie's disease from the larger cohort underwent the modified TEP. Mean increase in length of distal corpora was 2.8 ± 0.8 cm (range 2.0-3.4 cm) (measured using Furlow before and after penile eversion with TEP), while mean increase in girth (measured at midphallus prior to prosthesis insertion and after IPP inflation) was 1.6 ± 0.4 cm (range 1.2-2.2 cm). There were no reported complications. A scrotal approach to TEP is an easy to perform technique that can be used to restore length and enhance girth in men with Peyronie's disease undergoing insertion of IPP. Additionally, it is a customizable approach that can also be used to correct mild penile angulation.

Subcoronal inflatable penile prosthesis implantation: indications and outcomes

BACKGROUND

While implantation of an inflatable penile prosthesis (IPP) is commonly performed via infrapubic or penoscrotal approaches, the subcoronal (SC) approach for IPP implantation may safely and reliably allow for additional reconstructive procedures through a single incision.

AIM

The aim of this study is to report outcomes, including complications, of the SC approach and to determine common characteristics of patients undergoing the SC approach.

METHODS

A retrospective chart review from May 11, 2012, to January 31, 2022, was performed at a single, tertiary care institution to identify patients with IPP implantation via the SC approach.

OUTCOMES

Postoperative information was reviewed and extracted from all clinic notes available following the date of IPP implantation in the electronic medical record, detailing any complications including wound complications, need for revision or removal, device malfunction, and infections.

RESULTS

Sixty-six patients had IPP implantation via the SC approach. Median follow-up duration was 29.4 (interquartile range 14.9-50.1) months. One (1.8%) patient had a simple wound complication. Two (3.6%) experienced postoperative infection of the prosthesis, which resulted in explantation of the device. One of these infected prostheses later experienced partial glans necrosis. Revision for mechanical failure or unsatisfactory cosmetic result was performed in 3 (7.3%) IPPs placed via a SC incision.

CLINICAL IMPLICATIONS

The SC approach for implantation of IPP is safe and feasible with low complication and revision rates. It offers urologists an alternative to the classic infrapubic and penoscrotal approaches, both of which would require a second incision for additional reconstructive procedures required to adequately address deformities associated with severe Peyronie's disease. Therefore, urologists who treat these specialized populations of men may benefit from having the SC approach in their array of techniques for IPP implantation.

STRENGTHS AND LIMITATIONS

The limitations of this study include its retrospective nature, risk of selection bias, lack of comparison groups, and sample size. This study reports on early experience with the SC approach performed by a single high-volume reconstructive surgeon, who treats a specialized population of patients requiring complex repair during implantation of an IPP, particularly those with Peyronie's disease.

CONCLUSION

The SC incision for IPP implantation has low rates of complications and remains our approach of choice for IPP implantation in patients with severe Peyronie's disease, including curvatures >60°, severe indentation with hinge, and grade 3 calcification, which are unlikely to respond adequately to manual modeling alone.

The use of collagen fleece to correct residual curvature during inflatable penile prosthesis implantation (PICS technique) in patients with complex Peyronie disease: a multicenter study

BACKGROUND

The PICS technique (penile implant in combination with the sealing) was recently described as a valuable option to correct residual curvature during inflatable penile prosthesis (IPP) implantation in patients with complex Peyronie disease (PD).

AIM

To report the surgical and functional outcomes of the PICS technique in a multicentric series of patients.

METHODS

A consecutive series of patients with complex PD who underwent PICS were recruited. Patients were from 2 European tertiary referral centers. Data regarding baseline characteristics and perioperative, postoperative, and functional outcomes were retrospectively evaluated.

OUTCOMES

Complete penile straightness, duration of operative time and hospital stay, as well as postoperative complications (including hematoma, IPP infection, and IPP mechanical failure) were recorded, whereas functional outcomes were evaluated through the administration of validated questionnaires at baseline and 12 months postoperatively: International Index of Erectile Function-5, Sexual Encounter Profile questions 2 and 3 (SEP-2 and SEP-3), and Erectile Dysfunction Inventory of Treatment Satisfaction.

RESULTS

Thirty-seven patients with a median age of 62 years (IQR, 57-70 years) were enrolled. Median preoperative curvature was 75° (IQR, 65°-77°). Median residual curvature after IPP implantation was 60° (IQR, 50°-70°). Overall, 31 patients (84%) achieved a totally straight penis. Only 6 patients (16%) experienced a residual penile curvature (<20° in all cases) after the procedure. No intraoperative complications were detected. Nine patients (24%) developed an early postoperative complication, 3 (8%) a transient fever, and 6 (16%) a genital hematoma. A single case of IPP acute infection requiring device explantation was recorded. The survey response rate was 100%. At the 12-month follow-up evaluation, the median IIEF-5 score was 23.5 (IQR, 22.2-25) with evident improvement vs the baseline value of 10 (IQR, 8-12). Accordingly, 92% of the patients responded positively to SEP-2 and SEP-3. For the Erectile Dysfunction Inventory of Treatment Satisfaction, patients recorded a median postoperative value of 25 (IQR, 21-30) 1 year after PICS.

CLINICAL IMPLICATIONS

Complex PD is an end-stage disease featured by severe penile curvature, penile shortening, and erectile dysfunction: the gold standard approach is deemed to be penile prosthesis implantation, aiming to address penile curvature and erectile dysfunction, but in a limited percentage of cases, additional maneuvers are deemed necessary to manage residual penile curvature.

STRENGTHS AND LIMITATIONS

Our study has some limitations: the retrospective nature, relatively short follow-up, and limited number of patients.

CONCLUSION

The PICS technique may represent a reliable and effective treatment option to address significant residual curvature after IPP implantation.

Clinical Significance of Shortened Penile Length and Alterations in Penile Length Following Treatment for Peyronie's Disease

INTRODUCTION

Across many cultures, penis size has been associated with virility, and concerns about penile length are commonplace. Peyronie's disease (PD) is a known acquired cause of penile shortening.

OBJECTIVES

This paper describes the psychosocial impacts of penile length on men and their partners, both generally and in men with PD, and evaluates the effect of PD treatments (eg, collagenase clostridium histolyticum , surgery, mechanical therapy) on this outcome measure.

METHODS

A PubMed database search was performed for English language articles through July 2021. Main outcome measures were association of penile length with emotional well-being, selfesteem, and relationship satisfaction in men with PD, and change from baseline penile length after treatment.

RESULTS

Shortened penile length caused by PD can negatively impact patient and partner quality of life, including effects on body image, emotional well-being, sexual function, and interpersonal relationships. In men with PD, studies have demonstrated an association between loss of penile length and emotional problems, reduced satisfaction with sexual performance, poor self-esteem, depression, and relationship difficulties. Loss of penile length can frequently occur after surgery for PD (including plication, plaque incision/excision with grafting, and penile implant). Advanced surgical techniques may preserve/increase penile length, but the increased risks associated with these complex procedures must be carefully considered. Treatment with collagenase clostridium histolyticum does not appear to negatively impact penile length, and 5-year follow-up data suggest potential longterm posttreatment improvements in this outcome measure. Penile traction therapy, either alone or as adjunctive therapy, may increase penile length in men with PD, but nonadherence may limit improvement.

CONCLUSION

Changes in penile length are important to many men, particularly those with PD, and should be considered during PD treatment selection. Penile length should be measured objectively before and after treatment for PD and should be included as an outcome measure in future studies on treatment effectiveness.

Penile shortening complaints in males with erectile dysfunction: a narrative review on penile lengthening procedures during penile prosthesis surgery

Patients complaining of short penile length pose a challenge in urology practice. Those men who present seeking penile lengthening surgery usually overestimate 'normal' penile length, and may in often cases relate their penile length with the degree of masculinity and self-esteem. Penile prosthetic devices are the gold standard treatment of erectile dysfunction (ED) after failure of conservative options. Penile shortening is the most prevalent long-term complaint after successful inflatable penile prosthesis (IPP) placement. This has a significant impact on patient’s overall satisfaction and quality of life. Using PubMed, we performed a thorough literature review of the current procedures of preservation or enhancement of penile length as well as reported perioperative protocols in patients undergoing penile prosthesis (PP) insertion. Keywords used were “penile lengthening”, “penile enhancement”, “penile girth”, “inflatable penile prosthesis” and “glans augmentation”. Several surgical techniques can be offered in the setting of penile shortening concurrently with PP insertion, e.g., sub-coronal approach of PP placement, sliding technique, modified sliding technique (MoST), multiple-slide technique (MuST), and tunica mesh expansion procedure (TMEP). Adjuvant techniques can also improve subjective penile length include, ventral phalloplasty, suprapubic lipectomy, suspensory ligament release and use of expanding penile implants. Preoperative protocols including use of a vacuum erectile device, traction therapy also seem to improve postoperative outcomes, minimizing postoperative pain, and encouraging the early device use. Currently, there is no consensus among experts on a particular lengthening procedure or when they can be performed to optimize outcomes. Furthermore, it is imperative to set proper expectations before surgery, with extensive patient and partner counseling. When used in the properly selected patient, penile lengthening procedures show promising results with minimal complication rates.

Evolution of techniques for aesthetic penile enlargement during prosthesis placement: a chronicle of the Egydio non-grafting strategy

Since penile prostheses only provide axial rigidity, correction of penile deformity and enlargement of the visible penis during implant surgery may be desired. Evolving techniques of tunica expansion have made it possible to avoid grafting and preservation of the cylindrical appearance without bulges and indentations. After two decades of devising individualized solutions for patients and continuous enhancements of existing surgical solutions, Dr. Paulo Egydio has arrived at his Tunica Expansion Procedure (TEP). This strategy is his newest iteration of a lengthening techniques without grafting accompanied by penile prosthesis implantation. The TEP Strategy permits surgeons to use their own intuitive reasoning to determine the best pattern of multiple, small, staggered incisions to promote length and girth enlargement.

Advanced Penile Length Restoration Techniques to Optimize Penile Prosthesis Placement Outcomes

INTRODUCTION

The most common cause of patient dissatisfaction after penile prosthesis placement is penile shortening compared with one's memory of a natural erection. Surgical techniques as well as preoperative and postoperative protocols have been reported to preserve and possibly enhance penile length in someone undergoing penile prosthesis surgery.

OBJECTIVES

This article presents a description of as well as the authors' experience with presurgical protocols, intraoperative techniques, and postsurgical protocols that allow for preservation or enhancement of penile length for patients who undergo inflatable penile prosthesis insertion.

METHODS

An extensive, systematic literature review was performed using PubMed searching for key terms including penile lengthening, inflatablepenile prosthesis, penile girth, buried penis, and penile enhancement. All articles with subjective and/or objective penile length outcomes were reviewed.

RESULTS

Several preoperative treatment protocols were found for penile length preservation and enhancement, which included use of a vacuum erection device as well as traction therapy. Intraoperative techniques included cavernosal sparing, channeling without dilatation, circumferential penile degloving, ventral phalloplasty, suprapubic lipectomy, liposuction, suspensory ligament release, sliding technique, modified sliding technique, multislice technique, and aggressive implant sizing. Postoperative protocols included early device inflation and cycling. Table 1 summarizes and compares the various preoperative, intraoperative, and postoperative strategies identified during literature review with their corresponding reported length gain.

CONCLUSIONS

Many preoperative, intraoperative, and postoperative surgical techniques can be performed by high-volume implanters to improve one's perceived or true penile length. In the hands of experienced, high-volume implanters, these techniques can be very meaningful for patients undergoing penile prosthesis insertion, particularly those who are concerned with penile length.

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.

Augmentation Phalloplasty for Acquired Penile Shortening: A Systematic Review of Techniques, Outcomes, Patient Satisfaction, and Limitations

INTRODUCTION

Although an infrequent cause of small penile size in adult men, acquired penile shortening represents a particular reconstructive challenge due to preexisting penile anatomic deformities.

AIM

With numerous techniques being performed, the purpose of our study is to assess available literature on length enhancement procedures used for acquired penile shortening deformities.

METHODS

A systematic review was performed using the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-analyses. Medline/PubMed, Scopus, and Cochrane Databases were used to identify papers on augmentation Phalloplasty in non-transgender males with acquired penile shortening from 1990 to 2018.

MAIN OUTCOME MEASURE

Outcomes, complications, and patient-reported satisfaction were analyzed.

RESULTS

12 articles, involving 931 patients and 8 primary procedures, met our inclusion criteria. The majority of articles had level of evidence of 4 (83%) and Newcastle Ottawa Scale score of 6 (92%, moderate risk of bias). All studies reported mean penile length gain; however, inconsistent methodology was used when measuring penile dimensions. Mean length gain ranged from 0.6 to 6.4 cm. Overall, the mean complication rate for all techniques ranged from 0% to 50%. Post-operative satisfaction was reported in 10 (83%) studies, 7 of which used a validated scale. Patients were generally satisfied, with reported satisfaction rates ranging from 77% to 100%.

CLINICAL IMPLICATIONS

While numerous procedures have been described, the significant limitations in the available data preclude identifying a single superior procedure.

STRENGTHS & LIMITATIONS

The significant heterogeneity in the reported literature is a limitation of this study and highlights the need for standardized reporting. However, this study is the first to analyze augmentation phalloplasty literature in the setting of acquired penile shortening.

CONCLUSION

Augmentation phalloplasty techniques for acquired penile shortening are evolving and are continuously being modified; best-practice guidelines are crucial to achieve safe and satisfactory outcomes in this population.

Strategies and current practices for penile lengthening in severe Peyronie's disease cases: a systematic review

Several strategies to optimize penile length in the presence of Peyronie's Disease (PD) have been described so far. In case of severe curvature and preserved erectile function, plaque incision/excision (PIG/PEG) are advisable in order to maximize penile length, despite the risk of postoperative erectile dysfunction (ED), recurrent curvature, or penile shortening. For men with PD deformities associated to a certain degree of ED several lengthening techniques associated to penile prosthesis (PPI) implantation can be considered. Because of the potential postoperative complications, the indication must be balanced between patient's risk factors and surgeon's experience. Furthermore, adjuvant surgeries, such as prepubic V-Y plasty, suspensory ligament release, suprapubic lipectomy, and ventral phalloplasty, can be performed simultaneously or in a staged fashion to maximize the outcomes. Restoration a decent penile length in the case of a severe PD represents a real challenge for reconstructive surgeons. We present a systematic review of the literature on the current practices for penile lengthening in severe PD, providing the reader with a practical overview on the existing surgical strategies and their surgical and functional outcomes.

Preliminary Outcomes of the Male Urethral "Mini-Sling": A Modified Approach to the Andrianne Mini-Jupette Procedure With Penile Prosthesis Placement for Climacturia and Mild Stress Urinary Incontinence

INTRODUCTION

Previous worked showed that the Andrianne Mini-Jupette (AMJ) procedure with inflatable penile prosthesis (IPP) significantly improves climacturia or stress urinary incontinence (SUI) that may accompany erectile dysfunction (ED) after radical prostatectomy. However, with the AMJ procedure, the graft is incorporated into the medial aspect of the corporotomy, thereby requiring a more complex closure. Moreover, in the original report, multiple graft materials were used.

AIM

To describe our technique for "male urethral mini-sling" (MUMS) with a Virtue sling mesh, which is a modified approach to the AMJ, and to assess early postoperative outcomes.

METHODS

A retrospective chart review was performed for men who underwent IPP and MUMS placement with a modified Virtue mesh by 2 high-volume prosthetic urologic surgeons using the same technique. After proximal urethral exposure, the MUMS is sutured to the latera corpora over the bulbar urethra, proximal to and separate from the planned corporotomy, with care taken to avoid excessive urethral tension. The IPP is then placed in standard fashion. Changes in patient-reported climacturia and pads per day for SUI were assessed before and after surgery.

RESULTS

36 men underwent both IPP and MUMS placement between January 2016-October 2018. Mean patient age was 68 years. Etiology for ED and urinary symptoms was prostatectomy alone in 30 of 36 (83%) and prostatectomy plus radiation in 6 of 36 (17%). Preoperative urinary symptoms included climacturia in 30 of 36 (83%) and SUI in 27 of 36 (75%). Mean (SD) follow-up was 5.9 (3.7) months. Climacturia resolved in 28 of 30 (93%), and SUI improved in 23 of 27 (85%). The mean (SD) number of pads per day for those patients with SUI decreased significantly from 1.4 (1.1) before surgery to 0.4 (0.6) after surgery (P = .02). 1 patient required MUMS explantation for urethral erosion after prolonged postoperative catheterization.

CLINICAL IMPLICATIONS

The MUMS with modified Virtue mesh at the time of IPP placement can be used to treat ED with climacturia or mild SUI after radical prostatectomy.

STRENGTHS & LIMITATIONS

Strengths include the use of a consistent operative technique with a single graft material by 2 experienced prosthetic urologic surgeons. Limitations include the retrospective study design, use of subjective postoperative outcomes, lack of comparison group, and relatively moderate follow-up duration.

CONCLUSIONS

Our early results suggest that the MUMS significantly improves bothersome climacturia and mild SUI in addition to treating ED, with little added morbidity. Although further study, including longer-term follow-up, is needed, this approach may be considered in the appropriately counseled patient. Valenzuela RJ, Ziegelmann MJ, Hillelsohn JH, et al.

The use of penile traction therapy in the management of Peyronie's disease: current evidence and future prospects

Peyronie's disease is a disorder of abnormal and dysregulated wound healing leading to scar formation in the tunica albuginea of the penis. Penile traction therapy has emerged as an attractive therapeutic option for men with Peyronie's disease in both the acute and chronic phases. Currently, clinical studies are limited by lack of randomization, small cohorts, and lack of patient compliance with therapy. Despite these shortcomings, studies have shown a potential benefit with minimal morbidity. Specifically, penile traction may help to preserve or increase penile length and reduce penile curvature when used as monotherapy or as adjuvant therapy for surgical and intralesional treatments. Further study is necessary to define patient characteristics that are predictive of improved outcomes, determine the duration of treatment needed for clinical effect, and improve patient compliance.

Plication for Severe Peyronie's Deformities Has Similar Long-Term Outcomes to Milder Cases

INTRODUCTION

Penile plication (PP) for Peyronie's disease (PD) is an established treatment option for mild to moderate curvature, but scant data exist regarding its utility in severe deformities.

AIM

To evaluate long-term outcomes among men undergoing PP for PD, comparing severe to mild/moderate penile deformities.

METHODS

We performed a retrospective review of patients who underwent PP for PD between 2009 and 2017. All patients underwent multiple parallel tunical plication without degloving. Severe PD was defined as either curvature ≥60 degrees or biplanar curvature ≥35 degrees. Patient demographics and surgical outcomes were analyzed. A modified PD Questionnaire and International Index of Erectile Function (IIEF)-5 were administered by telephone.

MAIN OUTCOME MEASURE

Long-term patient-reported outcomes were evaluated from a modified survey incorporating the PD Questionnaire and IIEF-5.

RESULTS

Of 327 PP patients, 102 (31%) responded to the telephone survey at a median 59.5 months (interquartile range 28.3-84) since surgery. Patients were equally distributed into severe (n = 51) and mild/moderate (n = 51) groups. Despite a greater mean degree of curvature in severe compared to mild/moderate patients (71.6 degrees vs 37.7 degrees, respectively, P < .001), correction of penile curvature was achieved in 91% of patients, with a mean change of 60.7 degrees in severe cases compared to 31.4 degrees in mild/moderate cases (P < .001). Equal numbers of patients in severe and mild/moderate groups reported improvement of penile curvature (74.5% vs 74.5%, P = 1.0) and sexual function (51.0% vs 49.0%, P = .84). PD Questionnaire metrics were likewise similar between severe and mild/moderate patients (P > .1), as were rates of subjective penile shortening (62.7% vs 62.7%, P = 1.0) and IIEF-5, both pre-operatively (19.5 vs 19.7, P = .9) and post-operatively (19.4 vs 17.6, respectively, P = .15). On multivariate logistic regression, worsening sexual function was significantly associated with increased age (odds ratio 1.07, P = .01) and pre-operative IIEF (odds ratio 1.14, P = .02).

CLINICAL IMPLICATIONS

PP should be considered in PD patients with severe deformities, as outcomes are favorable and comparable to those with milder curvature.

STRENGTH & LIMITATIONS

This is a novel study evaluating long-term patient-reported outcomes after PP, comparing patients with severe deformity to those with mild/moderate curvature. The study was limited by retrospective design, relatively low survey response rate (31%), and lack of validated post-operative PD questionnaire.

CONCLUSION

Long-term patient-reported outcomes of PP for severe PD deformities are comparable to mild/moderate cases, supporting broader application of PP beyond milder deformities.

Penile Reconstructive Surgery in Peyronie Disease: Challenges in Restoring Normal Penis Size, Shape, and Function

To provide an overview of current approaches to penile reconstructive surgery in Peyronie disease (PD), and to discuss the challenges in restoring normal penile size and function. A systematic literature search was conducted to identify the published literature relevant to PD and penile reconstructive surgery. A summary of the published guidelines from major organisations is included in this review paper. Penile plication is simple and minimally invasive, and tends to preserve potency in most patients. However, plication invariably results in penile length loss and may, in fact, worsen the existing hour-glass or hinge effect. In contrast, graft reconstructive surgery can address issues relating to the loss of penile length and complex penile deformities, but long-term data highlight the risks of altered glans sensation, recurrent curvature, and/or loss of penile length from graft contracture, as well as the development of erectile dysfunction. Complex penile reconstruction with the concurrent placement of a penile prosthesis and/or graft material is a demanding operation that should be performed by surgeons with extensive prosthetic and reconstructive experience, as the risk of sensory loss, glans ischemia/necrosis, prosthesis-related complications, and failure to gain any meaningful length are serious concerns and cannot be underestimated. While surgical approaches remain the standard of care, they pose considerable risks and require prolonged postoperative rehabilitation. Obtaining proper informed consent and establishing realistic outcome expectations are imperative for successful postoperative outcomes.

2018 Canadian Urological Association guideline for Peyronie's disease and congenital penile curvature

Peyronie’s disease (PD) is a highly prevalent condition that affects the physical and psychosocial well-being and quality of life (QoL) for thousands of Canadian men. The specific etiology of PD remains poorly understood and there remains a paucity of randomized placebo-controlled trials evaluating treatment interventions.1-3 PD can be found in up to 8.9% of men, a remarkable increase in cited prevalence that is attributable to growing awareness (as historical data suggested a rate of less than 1%); the burden of disease is significant, and PD is often present in otherwise healthy men. The following guidelines were crafted by the committee with a full awareness of the limitations of the literature, and sought to provide actionable recommendations to guide PD care in the Canadian health system.

Penile Length: Measurement Technique and Applications

INTRODUCTION

Penile size has long been an important fixation in men's lives. On the one hand, a smaller penis has been associated with anxiety and apprehension; on the other hand, a larger penis has generally been related to virility and strength. These perceptions predominate during an erection, when penile size is representative of a man's masculinity.

AIM

To assess adult penile length and summarize average penile length assessments from the literature; analyze how various urologic diseases and therapies affect penile length and volume; and review how surgical treatments for Peyronie's disease, penile prosthesis implantation, and radical prostatectomy can affect penile size to appropriately counsel patients seeking such therapies and set realistic goals for patients.

METHODS

To achieve the aim of this review, we analyzed the literature on penile size and volume and how these can be affected by various urologic diagnoses and therapies. We summarize common diagnoses and therapies that can affect penile size.

MAIN OUTCOME MEASURE

We thoroughly discuss how the aforementioned diagnoses and therapies can negatively affect penile size. In doing so, we allow readers to understand the intricacies of penile size when faced with such diagnoses and therapies in their patients.

RESULTS

Surgical treatments for Peyronie's disease, penile prosthesis implantation for refractory erectile dysfunction, and radical prostatectomy for prostate cancer can lead to a decrease in penile size.

CONCLUSION

Urologists must recognize that the different therapies they offer can affect a man's penile size, often negatively. This in turn can lead to poorer satisfaction outcomes in patients.

Glans Necrosis Following Penile Prosthesis Implantation: Prevention and Treatment Suggestions

OBJECTIVE

To examine possible etiology and treatment outcomes in 21 patients with glans necrosis following penile prosthesis implantation.

METHODS

Glans necrosis typically presented with a dusky glans on the first postoperative day following prosthesis implantation.

RESULTS

The blood supply to the glans penis consists of the dorsal arteries and the terminal branches of the spongiosal arteries. Using the cohort in our study, we compiled preoperative comorbidities and adjunctive surgical maneuvers that might compromise glans vascularity, leading to glans necrosis. Preoperative risk factors were arteriosclerotic cardiovascular disease (90%), diabetes mellitus (81%), smoking (81%), previous prosthesis explantation (57%), and previous radiation therapy (48%). The most prevalent intraoperative and postoperative factor was subcoronal incision for reasons as simple as coincident circumcision or as complex as for penile degloving (86%). Other factors detected were penile wrapping with an occlusive elastic bandage (62%), use of a sliding technique for penile lengthening (33%), and coincident distal urethral injury repair (29%). Seventeen patients (81%) managed expectantly with preservation of implanted prosthesis sustained significant glandular loss. Four patients managed with immediate prosthesis removal healed without sequelae.

CONCLUSION

Patients with preoperative risk factors undergoing penile prosthesis implantation should avoid high-risk adjunctive surgical maneuvers. Upon development of signs of glans necrosis postoperatively, in the setting of these high-risk factors, immediate implant removal may prevent subsequent glans necrosis.

Penile Lengthening, Girth, and Size Preservation at the Time of Penile Prosthesis Insertion

INTRODUCTION

Penile prosthetic devices are the gold standard treatment of medication-refractory erectile dysfunction. Inflatable penile prosthetic (IPP) devices have been available and used for more than four decades. Oftentimes, medical conditions causing erectile dysfunction also cause penile shortening, causing decreased patient quality of life.

AIM

To identify and review all available penile lengthening procedures that can be performed at time of IPP insertion.

METHODS

An extensive, systematic literature review was performed using PubMed searching for key terms penile lengthening, inflatable penile prosthesis, penile girth, corporoplasty, glans augmentation, and penile enhancement; all articles with subjective and/or objective penile length outcomes were reviewed.

MAIN OUTCOME MEASURES

A review of various techniques for penile length and girth preservation and enhancement during penile prosthesis insertion.

RESULTS

Several advanced and novel techniques were found for penile length preservation and enhancement at time of IPP insertion, including the sub-coronal IPP insertion technique, and adjuvant maneuvers during insertion, such as the sliding technique, modified sliding technique, multiple slice technique, and circumferential incision and grafting. Other adjuvant techniques that can enhance perception of increased length include ventral phalloplasty, suprapubic lipectomy, and suspensory ligament release. Further enhancement can be obtained using augmentation corporoplasty and glans augmentation with hyaluronic acid and other fillers. The different techniques vary in complexity and could require specialized training and experience. Maximum length gain appears to be limited by the length of the neurovascular bundles.

CONCLUSION

Overall, surgical penile lengthening procedures at time of IPP insertion appear safe and effective for treatment of patients with penile shortening and severe erectile dysfunction. These therapies can significantly improve patient self-esteem and quality of life in properly selected patients. Tran H, Goldfarb R, Ackerman A, Valenxuela RJ.
