Plication surgery does not produce additional loss of length in Peyronie's disease patients

Nesbit's procedure remains a cornerstone in surgical management of Peyronie's disease, despite the subjective loss of penile length. This retrospective study demonstrates that the perceived length loss has already occurred prior to surgery and that the Nesbit's procedure does not produce additional loss of length. Ninety-one patients who had undergone Nesbit's procedure between 2017 and 2022 at the Department of Urology of the University of Trieste were enrolled in the study. Preoperative stretched penile length and postoperative stretched penile length were measured. The curvature was uniplanar in 78 patients and biplanar in the remainder. Mean degree of the main curvature was 52.58° ± 14.13° and mean number of plications was 2.42 ± 1.07. Analysis revealed that the median of the differences between preoperative stretched penile length and postoperative stretched penile length was not significant (p = 0.466). According to our results, no significant penile shortening occurs as immediate consequence of Nesbit's procedure, as length is defined by the shorter side of the shaft affected by Peyronie's disease. Hence the length loss should have to be attributed to Peyronie's disease itself and could have been accurately predicted preoperatively allowing for a more accurate counseling of patients. Further studies are pending to assess potential postoperative loss of length due to scarring contracture.

Surgical tips in difficult penile prosthetic surgery: a narrative review

Penile prosthesis implantation continues to represent a reliable solution to address erectile dysfunction when oral medications fail, are not tolerated or are contraindicated, and most typically is associated with excellent satisfaction rates and durable results. Despite the dramatic improvements in the prostheses' design, in the surgical instruments and techniques over the years, certain categories of patients still pose a significant surgical challenge. The aim of the current review is to provide a quick and useful practical guidance based on our expertise in the identification and management of the difficult penile prosthesis implantation cases. A narrative review design was here preferred to fulfil our purpose. The search strategy included a range of terms, e.g. penile prosthesis, corporal fibrosis, infection, ischaemic priapism, Peyronie's disease, radical prostatectomy, pelvic surgery. Extensive corporal fibrosis after explantation of an infected device or after prolonged ischaemic priapism may represent the most difficult situations to deal with in penile prosthesis implantation surgery. Penile prosthesis implantation in patients with Peyronie's disease and in those who previously underwent radical prostatectomy also presents with an increased risk of complications. Experienced surgeons need to be able to recognise promptly and manage urethral perforation, cylinder crossover, tunical perforation and erosion, as these complications are more common when dealing with difficult penile prosthesis implantation cases. Applying penile lengthening techniques and principles can be useful in selected cases to ensure better postoperative satisfaction rates, especially in those patients who have experienced a more significant degree of loss of length preoperatively. High-volume-implanting surgeons should always be involved in complex cases to minimise the risk of complications. A thorough preoperative counselling can set realistic patients' expectations in this context, further contributing to postoperative satisfaction.

Validation of the Italian version of the Peyronie's Disease Questionnaire (PDQ)

Peyronie's disease (PD) is a connective tissue disorder characterized by the formation of fibrous plaques in the tunica albuginea of the penis which can result in pain, deformity and erectile dysfunction (ED). The Peyronie's Disease Questionnaire (PDQ) assesses the severity of symptoms, including pain, penile curvature and ED, as well as the impact on sexual function, emotional well-being, and overall quality of life of PD patients. Previous studies validated the PDQ in languages other than English and confirmed its test-retest reliability and clinical utility. Despite this, in many countries the unavailability of an adequate PDQ validation in native language hampers its use in clinical practice. In the present non-interventional, observational study we aimed at validating the Italian version of the PDQ (PDQ-I). Between January 2019 and November 2021, 79 PD patients from 6 Italian high-volume centers were administrated the PDQ-I in two separated office visits distanced by a period of 6 months. Intraclass correlation coefficients (ICCs) were used to evaluate the association between the three PDQ scale scores at visit 1 and 2. Paired t-tests were used to evaluate significant score changes between the 2 visits. Cronbach's alpha was used to assess internal consistency reliability. PDQ-I demonstrated an excellent test-retest reliability in the Italian population (ICC 0.78-0.92) as well as a strong internal consistency, with all three scale scores showing a Cronbach's alpha coefficient above 0.70. PDQ-I proved to be a useful tool which allows to reliably evaluate Italian PD patients' quality of life in both everyday andrological practice and clinical research. External validation of our results is pending.

Value of prolonged scrotal drainage after penile prosthesis implantation: a multicenter prospective nonrandomized pilot study

We aimed to understand the risks and benefits of post-inflatable penile prosthesis (IPP) implantation drainage and optimal duration. Our patients were divided into 3 groups: Group 1 (n = 114) had no drain placed, Group 2 had a drain placed for 24 h (n = 114) and Group 3 had a drain placed for 72 h (n = 117). Postoperative scrotal hematoma and prosthesis infection rates were compared between the groups. The patients from Group 3 demonstrated a statistically significant lower incidence of hematoma on the 10th postoperative day: (n = 1, 0.9%) compared to Group 2: (n = 11, 9.6%) and Group 1: (n = 8, 7%), (p = 0.013). However, on the 3rd postoperative day, there was a statistically significant lower incidence of hematoma in both Groups 3 and 2: (0.9% and 6.1%, respectively) vs. Group 1: (11.4%), (p = 0.004). Hematoma rates followed the same group order after the first day of surgery: 1.7% (n = 2), 5.3% (n = 6), and 8.8% (n = 10), respectively, (p = 0.05). Five patients (4.4%) in Group 1 and four patients (3.5%) in Group 2 developed an IPP associated infection, opposed to only a single patient (0.85%) in Group 3, (p = 0.210). We concluded that prolonged scrotal drainage for 72 h after virgin IPP implantation significantly reduces hematoma and infection rates.

Procalcitonin as prognostic factor in patients with Fournier’s gangrene

Introduction:

Fournier’s Gangrene (FG) has still a mortality rate up to 45%. Several studies identified prognostic factors but there is a knowledge gap concerning procalcitonin (PCT) levels and mortality risk in FG. This study is aimed to assess the role of PCT as prognostic factor in FG.

Materials and methods:

The medical records of 20 male FG patients admitted at the Department of Urology of “Cattinara” Hospital, University of Trieste between January 2019 and November 2020 were retrospectively reviewed. Clinical, demographic, microbiological data were collected. The Fournier’s Gangrene Severity Index (FGSI) was calculated for each patient.

Results:

Thirteen (65%) of 20 patients survived. Median age was 58 years (IQR 51–88), 15 patients (75%) had a Charlson Comorbidity Index (CCI) score ⩾2, 1 (5%) equal to 0, 4 to 1 (20%). Median FGSI score was 6 (IQR 2–12) and median PCT 0.8 ng/ml (IQR 0.04–2.12). At multivariate analysis PCT levels >0.05 ng/ml were associated with an increased overall mortality risk (OR 2.14, CI 1.25–4.27, p = 0.002). CCI score ⩾2 (OR 1.51, CI 1.01–2.59, p = 0.04), Streptococcical etiology (OR 3.41, CI 2.49–4.61, p = 0.002) and FGSI score >9 (OR 1.41, CI 1.19–2.21, p = 0.004) were associated with unfavorable outcome.

Conclusion:

PCT might be a prognostic factor in FG. CCI and FGSI are useful tools in mortality risk stratification. Streptococcical etiology is associated with unfavorable outcome. Further larger clinical trials are pending.

Penile prosthesis impending erosion: Surgical technique for extracapsular re-implantation reconstruction

Introduction and objectives:

Impending erosion is an unusual complication of inflatable penile prosthesis that can strongly impact on patient’s morbidity and quality of life. In this case report we present a salvage surgery technique for impending erosion performed in a 57-year-old man.

Materials and methods:

We present our surgical technique for cylinder reimplantation in an impending erosion of a three-component inflatable prosthesis with a peno-scrotal access and extracapsular reseating of the cylinder.

Results:

No post-operative complication occurred, and the patient regained full function of the prosthesis after recovery. The surgical site healed well with no signs of infections.

Conclusions:

Impending erosion is a problematic complication of penile prosthesis; however, can be administered with a salvage technique avoiding the explant of the IPP.

Multidisciplinary approach and management of patients who seek medical advice for penile size concerns: a narrative review

We aimed to provide an overview of the strategies available to manage patients concerned about their penile size and to provide useful surgical hints regarding the most common penile enlargement approaches, based on our surgical expertise in this field. A comprehensive research was carried out on MEDLINE/PubMed database to identify pertinent studies concerning penile enlargement issues. The search strategy included a range of keywords; e.g. penis, penile, enlargement, augmentation, lengthening, girth. Management of penile size-related concerns represents a real challenge for the urologist, especially when dealing with patients suffering from penile dysmorphophobic disorder (PDD). A multidisciplinary preoperative assessment, including a psychiatric/psychological evaluation, may help in discerning those patients who would benefit the most from counselling/conservative management from those who would benefit from surgery instead. Conservative approaches include the use of vacuum-based and penile-stretching devices, which have shown encouraging levels of efficacy and safety. Over the last decades, different surgical strategies have been developed, aimed at either increasing flaccid penile length or improving penile girth. Penile lengthening procedures are more established, and satisfactory results can be achieved by experienced, large referrals' volume, surgeons. To date, there is lack of consensus regarding the penile girth enhancing techniques, and therefore these should be regarded as experimental. A multidisciplinary approach is necessary to identify patients with PDD, who should not be offered surgical intervention and should be referred for psychiatric/psychological counselling instead. The surgical approach should be tailored to the subject's unique anatomy and underlying conditions.

Plaque excision with the Shah Penile Implant™ and tunica vaginalis graft in Peyronie's disease with erectile dysfunction: A case report

Peyronie's disease (PD) is a condition characterized by the deposition of scar tissue in the tunica albuginea of the penis. Peyronie's disease often causes pain, worsens the quality of erections, a variable degree of penile deformation and shortening, which can cause severe distress for the patient and the partner and impact negatively on self-esteem and quality of life in general. Surgery still represents the gold standard treatment for PD in the chronic phase, and it aims to guarantee a penis straight and rigid enough to allow the patient to resume penetrative sex with confidence. Penile prosthesis implantation should be reserved for patients with refractory erectile dysfunction or in these patients with complex deformities and impaired erections. Herein is reported the case of a 51-year-old male with a large ossified PD plaque and erectile dysfunction who underwent simultaneous plaque excision and grafting and penile implantation surgery with a semirigid penile prosthesis. This was the first case of penile prosthesis implantation for Peyronie's disease in Indonesia.

ESSM Position Statement on Surgical Treatment of Peyronie's Disease

INTRODUCTION

Patients with Peyronie's disease may experience significat distress. The choice of treatment depends on a variety of factors, including the stage of the disease, the presence of pain, severity and direction of the curvature, penile length and the quality of erectile function.

AIM

To review the evidence associated with surgical treatment of Peyronie`s Disease and provide clinical recommendations on behalf of the European Society for Sexual Medicine. 131 peer-reviewed studies and systematic reviews, which were published from 2009 to 2019 in the English language, were included.

METHODS

MEDLINE, Google Scholar and EMBASE were searched for randomized clinical trials, meta-analyses, open-label prospective and retrospective studies.

MAIN OUTCOME MEASURE

The panel provided statements on clinically relevant questions including patient involvement in the decision process, indications for surgery, choice of the approach, and the management of patient expectations. A comparison of the different grafts used in patients who have undergone plaque incision/excision and grafting in order to identify an ideal graft, has been carried out. The prevalence of postoperative complications has been summarized. Levels of evidence were provided according to the Oxford 2011 criteria and Oxford Centre for Evidence-Based Medicine recommendations.

RESULTS

In order to allow shared decision making, a patient preoperative counselling regarding the pros and cons of each intervention is recommended. In particular, adverse effects of surgical treatments should be discussed to set realistic understanding and expectations of surgical outcomes and ultimately improve postoperative satisfaction rates. Surgical treatment should be only offered in the chronic phase of the condition, when the deformity and/or degree of erectile dysfunction, prevent patients from engaging in satisfying sexual interaction, or if the deformity is the cause of severe bother.

CONCLUSIONS

Current European Society for Sexual Medicine recommendations cover several aspects of Peyronie's disease treatment. These recommendations aim both to ensure patients and partners have accurate and realistic expectations of their treatment options, as well as to formulate algorithms to guide clinician management pathways.

Analysis of clinical utility of abdominopelvic computed tomography in the follow-up of Stage I seminoma: a single center evaluation

BACKGROUND

Abdominopelvic computed tomography (CT) is widely used in the follow-up of seminoma patients after radical orchidectomy. The aim of this study was to evaluate the clinical utility of abdominopelvic computed tomography in the follow-up of patients with Stage I seminoma.

METHODS

The pathological reports of all patients that have undergone radical orchidectomy in our tertiary referral center between January 2002 and January 2018 have been retrospectively reviewed. All patients with Stage I seminoma and negative serum tumor markers after radical orchidectomy were included. Patients with follow-up shorter than 12 months were excluded. Surveillance records of every patient were reviewed with regard to abdominopelvic imaging.

RESULTS

Of the 133 patients who have undergone radical orchidectomy in our center, 55 had Stage I pure seminoma with normal levels of serum tumor markers after surgery. Two patients were excluded as the follow-up was inadequate. Mean follow-up was 63.2 months (IQR: 30-73). The results of 211 abdominopelvic CTs performed as part of the follow-up were reviewed. Two (3,7%) patients developed recurrence; one consisted of a scrotal lump and was diagnosed with ultrasonography (US) while the second appeared as paraaortic nodal metastasis and was diagnosed with abdominopelvic CT. The recurrence was successfully treated in both patients. A single abdominopelvic CT was useful for the detection of recurrent disease in our entire study population. No cancer specific death has been reported in the study population.

CONCLUSIONS

Follow-up schedules for Stage I seminoma expose patients to potential risks of radiation-induced tumors, emotional distress and represent a significant burden for the healthcare system. The current series suggests that a better risk adapted patient-tailored follow-up program is needed in order to avoid unnecessary investigations.

Cadaveric Penile Prosthesis Workshop training improves surgical confidence levels of urologists: South Asian Society for Sexual Medicine course survey

OBJECTIVES

To analyze the impact of South Asia's first cadaveric hands-on workshop on urologists' training in inflatable penile prosthesis surgery.

METHODS

A total of 72 urologists/andrologists participated in the 2019 South Asian Society for Sexual Medicine Pre-congress Penile Prosthesis hands-on workshop. The workshop included 4 h of lectures and 2 h of hands-on cadaveric laboratory experience using three-piece inflatable penile prosthesis. The Shapiro-Wilk test was used on self-rated procedural confidence levels, which proved the normality. A non-parametric McNemar test was used to examine the change in the number of correct answers.

RESULTS

Of those who attended the cadaver laboratory, just 45 who answered the survey both before and after the workshop were included for analysis. Significant objective improvements were noted in procedural knowledge test scores (44.30 ± 0.027 vs 72.44 ± 0.024, P < 0.05) and median surgical confidence levels (4 vs 3 and 2, P < 0.001) of the urologists after the completion of the workshop.

CONCLUSIONS

Cadaveric hands-on workshop training improves urologists' procedural knowledge and surgical confidence levels in carrying out three-piece inflatable penile prosthesis surgery. The feasibility of such workshops should be considered in increasing the surgical expertise of general urologists in prosthetic urology.

The logistical management of tertiary urethral disease in the United Kingdom: Implications from an online audit of male reconstructive urethral surgery

Objective:

To determine those patient groupings, based on volume and risk, whose optimal urethral reconstructive management might be provided by a reorganisation of UK reconstructive surgeons.

Methods:

Between 2010 and 2017, ~689 men/year were enrolled onto an online audit platform collecting data about urethral reconstruction in the UK; this accrual was compared against hospital episode statistics (HES). The available workforce, and where this was based, was collected. Individual and institutional incumbent patient volumes, pathology, surgical complexity and outcomes from treatment were collated to stratify volume/risk groups.

Results:

More than 90% of all HES-recorded data were accrued, being provided by 50 surgeons at 39 operative sites. Most reconstructive surgery was provided at 10 centres performing >20 procedures/year. More than 50% of all interventions were of a high-volume low-risk type. Of activity, 32.3% was intermediate volume or moderate risk, and 12.5% of men presented for lower-volume or higher-risk procedures.

Conclusion:

Correlation of detailed volume/outcome data allows the definition of patient populations presenting for urethral reconstruction. Stratification of each group’s management, to optimise the surgical outcome, may be applied to a hierarchical service delivery model based on the complexity of the patient’s presenting urethral pathology.

Level of evidence:

Clinical Recommendations From the European Society for Sexual Medicine Exploring Partner Expectations, Satisfaction in Male and Phalloplasty Cohorts, the Impact of Penile Length, Girth and Implant Type, Reservoir Placement, and the Influence of Comorbidities and Social Circumstances

INTRODUCTION

To date, several aspects of inflatable penile prosthesis (IPP) surgical procedure have been poorly studied.

AIM

The aim of this study was to review the evidence associated with IPP implantation and provide clinical recommendations on behalf of the European Society for Sexual Medicine (ESSM). Overall, 130 peer-reviewed studies and systematic reviews, which were published from 2007-2018 in the English language, were included.

METHODS

MEDLINE and EMBASE were searched for randomized clinical trials, meta-analyses, and open-label prospective and retrospective studies.

MAIN OUTCOME MEASURE

The panel provided statements exploring patients and partner expectations, satisfaction in male and phalloplasty cohorts, the impact of penile length, girth and implant type, reservoir placement, the influence of comorbidities, and social circumstances. Levels of evidence were provided according to the Oxford 2011 criteria and graded as for the Oxford Centre for Evidence-Based Medicine recommendations.

RESULTS

In the preoperative setting, it is fundamental to identify and interact with difficult patients with the intention of enhancing the surgeon's ability to establish the surgeon-patient relationship, reduce physical and legal risk, as well as enhancing patient satisfaction. To address this need, the mnemonic Compulsive, Unrealistic, Revision, Surgeon Shopping, Entitled, Denial, and Psychiatric ("CURSED") has been suggested to identify patients who are at high risk of dissatisfaction. The current recommendations suggest improving glycemic control in patients with diabetes. Available evidence suggests evaluating transplant recipients with the criteria of Barry, consisting of stable graft function for >6 months, avoidance of intra-abdominal reservoir placement, and low-dose immunosuppression. HIV status does not represent a contraindication for surgery. Smoking, peripheral vascular disease, and hypertension may be associated with an increased risk of revision surgery. Patients with spinal cord injury may receive IPP. Patients aged ≥70 years, as well as obese patients, can be offered IPP. The IPP implantation can be performed in patients with stable Peyronie's disease. Ectopic high submuscular reservoir placement can be considered as an alternative method.

CLINICAL IMPLICATIONS

There is a relevant lack of high-level data and definite conclusions in certain areas remain difficult to draw.

STRENGTH & LIMITATIONS

All studies have been evaluated by a panel of experts providing recommendations for clinical practice. Because of lack of sufficient prospective data, some of the included studies are retrospective and this could be stated as a limitation.

CONCLUSION

This ESSM position statement provides recommendations on optimization of patient outcome by patient selection, and individualized peri- and intra-operative management. ESSM encourages centers to collaborate and to create prospective, multicenter registries in order to address this topic of increasing importance. Osmonov D, Christopher AN, Blecher GA, et al.

Comparison of Intralesional Hyaluronic Acid vs. Verapamil for the Treatment of Acute Phase Peyronie's Disease: A Prospective, Open-Label Non-Randomized Clinical Study

Purpose

To compare the efficacy and safety of intralesional hyaluronic acid (HA) as compared with verapamil injection in patients with Peyronie's disease (PD).

Materials and Methods

Between January 2015 and December 2018, men in PD acute phase were prospectively recruited. This open-label, prospective study included 2 different protocols. Group A: 8-week cycle of weekly intraplaque injections with HA; Group B: 8-week cycle of weekly intraplaque injections with verapamil. Penile curvature, plaque size, International Index of Erectile Function (IIEF)-15 score and visual analogue scale (VAS) were assessed at baseline and after 3 months.

Results

Two-hundred forty-four patients were enrolled. Of these, 125 received intralesional HA (Group A), 119 received intralesional verapamil (Group B). At enrollment, median age was 56.0 years (interquartile range [IQR]=47.0–63.0 years), median curvature 35.0° (IQR=25.0°–45.0°), median IIEF-15 score 19.0 (IQR=16.0–23.0), median VAS 4.0 (IQR=4.0–5.0). Median difference for IIEF-15 was 1.0 (95% confidence interval [CI]=1.12–1.94) in Group A and 0.0 (95% CI=−0.04–0.14) in Group B (p<0.05) and median difference for VAS score was −4.0 (95% CI=−4.11–−3.65) in Group A and −1.0 (95% CI=−0.50–2.01) in Group B (p<0.05). Plaque size decreased by −1.50 mm (IQR=1.60–2.10 mm) in Group A and −1.20 in Group B (p=0.10), while penile curvature decreased by −9.50° (IQR=4.50°–13.00°) in group A and −4.50 (IQR=2.50–7.50) in Group B (p<0.01).

Conclusions

Intralesional HA injections could represent a reliable treatment option for the conservative management of patients with acute phase of PD.

The current series suggests that a better risk adapted patient-tailored follow-up program is needed in order to avoid unnecessary investigations.

Predictive Factors of Patients' and Their Partners' Sexual Function Improvement After Collagenase Clostridium Histolyticum Injection for Peyronie's Disease: Results From a Multi-Center Single-Arm Study

BACKGROUND

Collagenase Clostridium histolyticum (CCH; Xiapex) injections represent the only licensed medical treatment for Peyronie's disease (PD).

AIM

To evaluate the efficacy and safety of CCH injections in men with stable PD, using a modified treatment protocol and to assess partners' bother improvement in a large cohort of White-European sexually active heterosexual men treated in a single tertiary-referral center.

METHODS

All the 135 patients enrolled underwent a thorough assessment, which included history taking, physical examination, and pharmacologically induced artificial erection test (intra-cavernous injection) to assess the degree of penile curvature (PC) at baseline and after the completion of the treatment. Patients with calcified plaque and/or ventral curvature were excluded. All patients underwent a modified treatment protocol, which consisted of 3 intra-lesional injections of 0.9 mg of CCH performed at 4-week intervals at the point of maximum curvature. After each injection, patients were instructed to follow a strict routine involving daily penile stretching in the intervals between injections.

OUTCOMES

International Index of Erectile Function (IIEF)-15, Global Assessment of PD, PD questionnaires (PDQ), and Female Sexual Function Index (FSFI) questionnaire were performed at baseline and at the end of treatment.

RESULTS

Overall, 135 patients completed the study protocol. Before treatment, 18 (13.33%) partners showed a degree of sexual dysfunction. Baseline median IIEF-15, FSFI, and PDQ scores were, respectively, 59.0, 35.0, and 23.0. Overall, both IIEF-total and all domains significantly improved after treatment (all P < .01). A PC mean change of 19.07 (P = .00) was measured. At the univariate linear regression analysis, IIEF-15, IIEF-erectile function, IIEF-sexual desire, and IIEF-intercourse satisfaction were positively associated with FSFI (all P ≤ .03); conversely, PDQ-penile pain, PDQ-symptom bother, and post-treament penile curvature (P ≤ .04) were associated with a decreased FSFI score. Furthermore, median change of PC was significantly associated with median change of FSFI (r = 0.25; 95% CI 0.02-0.11; P = .004). Global satisfaction after treatment was 89.6% (121/135).

CLINICAL TRANSLATION

This modified CCH treatment protocol could improve both patients' and partner's sexual function.

STRENGTH AND LIMITATIONS

This was an open-label, single-arm clinical study, without placebo. where only heterosexual couples in stable relationships were included. Furthermore, no real assessment of female sexual distress was carried out and long-term sexual function in both patients and female partners were not taken into account.

CONCLUSIONS

The modified treatment schedule with CCH injections for stable PD has a positive impact on both patients' and partners' sexual function in heterosexual couples with a stable sexual relationship.

Subjective and objective results in surgical correction of adult acquired buried penis: A single-centre observational study

Objective: The purpose of this study was to provide a detailed analysis of surgical and functional outcomes after correction of acquired buried penis in the adult. Materials and Methods: From 2006 to 2016, we retrospectively reviewed 47 patients undergoing surgical treatment for the correction of buried penis. Functional and surgical outcomes, as well as patients’ satisfaction were the main endpoints. Results: The most common complains at presentation were recurrent uro-genital infections, sexual dysfunction, voiding dysfunction and Lichen Sclerosus (LS). Surgical management steps included: circumcision (27.66%), scrotoplasty (19.14%), V-Y skin plasty (4.25%), split thickness skin graft (STSG) 12.76%, full thickness skin graft (FTSG) 36.17%, suprapubic fat pad excision (57.44%), abdominoplasty (25.53%), division of the suspensory ligament (36.17%). Postoperative complications were recorded in 15% of patients. Vaginal penetration and erectile function ended up being more effective in 97.87% (46/47) and 42.55% (20/47) of patients. Improvement in penile erogenous sensation was in 6.38% (3/47). Aesthetic appearance of genitalia fully satisfied 36.17% of patients (17/47). Overall patients’ satisfaction rate resulted 76.59% (36/47). Conclusion: Management of adult acquired buried penis still remains a challenging task to achieve, however excellent cosmetic results can be obtained by surgical reconstruction.

Impact of advanced paternal age on the intracytoplasmic sperm injection (ICSI) outcomes in donor egg cycles

Background

The purpose of this study is to assess the impact of paternal age on the oocyte-donation outcomes in intracytoplasmic sperm injection (ICSI) cycles.

Methods

Two hundred and seventy-eight infertile couples were retrospectively involved. Inclusion criteria were: infertility from almost 1 year, normal or sub-fertile seminal parameters, overall oocyte survival rate greater than 85%. Baseline characteristics included male age, recipient age, male body mass index (BMI), smoking, drinking status. Main outcome measures: fertilization rate (FR), cleavage rate (CR), pregnancy rate (PR).

Results

Patients were categorized in group 1 ≤45, group 2 >45 years. A total of 1,724 frozen oocytes were included. After warming, 1,642 oocytes survived. Median overall oocyte survival rate was 100% [interquartile range (IQR), 85-100%]. Median male age was 44±5.60 years (IQR, 31-70 years). Median recipients age was 42±3.62 years (IQR, 29-50 years). Group 1 included 166 men, group 2 112 men. Two hundred and seventy-eight fresh ICSI cycle were performed. "Two-pronuclear" (2PN) FR was 72.6%±0.20%, CR 93.0%±0.16%, PR 39.6%. Miscarriage rate was 25.5%. Live birth rate per cycles was 29.5%. Comparison between group 1, group 2 and ICSI outcomes confirmed an association with FR, resulting 80.0% (IQR, 67.0-83.0%) and 67.0% (IQR, 50.0-80.0%), respectively (P<0.01). There were no significant differences between the two groups with respect to seminal parameters.

Conclusions

It would be recommended more emphasis on the advancing male age when counselling older couples who undergo egg donation program.

Novel method of histopathological analysis after testicular sperm extraction in patients with nonobstructive and obstructive azoospermia

Objective

To assess whether the “testicular pool” could be used for histological analysis and whether it gave more accurate information than the standard testicular biopsy.

Methods

Between January 2017 and March 2018, this single-center prospective study included 60 azoospermic men undergoing conventional bilateral testicular sperm extraction. Six samples were excised from each testicle and transferred to an embryologist. One additional biopsy was randomly taken from each testis for a histological analysis. After processing, the testicular pool was also sent for a histological analysis, which showed normal spermatogenesis (NS), hypospermatogenesis (HYPO), maturation arrest (MA), Sertoli cell-only syndrome (SCOS), and tubular atrophy (TA).

Results

Twenty of the 60 patients (33.3%) had obstructive azoospermia (OA), while the remaining 40 (66.6%) had nonobstructive azoospermia. Their mean age was 40.5 years. All patients with OA had previously undergone unsuccessful testicular fine-needle aspiration. Successful sperm retrieval (SSR) occurred in 93.3% of patients. Histological analysis of the testicular biopsy revealed NS in 12 patients (20%), HYPO and TA in 28 patients (46.6%), MA in eight patients (13.3%), and SCOS in 12 patients (20%). The testicular pool analysis showed NS in 12 patients (20%), HYPO and TA in 44 patients (73.3%), MA in four patients (6.6%), and SCOS in no patients. In four patients with MA (6.6% of the total sample) and 12 patients with SCOS (20% of the total sample) according to the standard testicular biopsy, the embryologist found SSR with cryopreservation. Overall, in 44 patients (73.3%), the testicular pool analysis confirmed the histological findings of the standard testicular biopsy. In the 16 cases (26.6%) with a discrepancy between the single-biopsy histological findings and SSR, the testicular pool analysis confirmed the embryological data on SSR.

Conclusion

The testicular pool proved to be easily analyzable, practical, manageable, and more accurate for predicting sperm retrieval than standard testicular biopsy.

Intratunical Injection of Human Adipose Tissue-Derived Stem Cells Restores Collagen III/I Ratio in a Rat Model of Chronic Peyronie's Disease

Introduction

Previous studies have shown that the injection of adipose tissue–derived stem cells (ADSCs) into the tunica albuginea (TA) during the active phase of Peyronie’s disease (PD) prevents the development of fibrosis.

Aim

To investigate, using an animal model, whether local injection of human ADSCs (hADSCs) can alter the degree of fibrosis in the chronic phase of PD.

Methods

27 male, 12-week-old rats were divided into 3 equal groups: sham, PD without treatment, and PD treated with hADSCs 1 month after disease induction. Sham rats underwent 2 injections of vehicle into the TA 1 month apart. PD rats underwent transforming growth factor β1 (TGFβ1) injection and injection of vehicle 1 month later. PD-hADSC rats underwent TGFβ1 injection followed by 1 million hADSCs 1 month later. 1 week after treatment, n = 3 animals/group were euthanized, and the penises were harvested for quantitative polymerase chain reaction. 1 month after treatment, the other animals, n = 6 per group, underwent measurement of intracavernous pressure (ICP) and mean arterial pressure (MAP) during electrostimulation of the cavernous nerve. After euthanasia, penises were again harvested for histology and Western blot.

Main Outcome Measure

The primary outcome measures included (a) gene expression at one week post-injection; (b) measurement of ICP/MAP upon cavernous nerve stimulation as a measure of erectile function; (c) elastin, collagen I and III protein expression; and (d) Histomorphometric analysis of the penis. Means where compared by analysis of variance (ANOVA) followed by a Student-Newman-Keuls test for post hoc comparisons or Mann-Whitney test when applicable.

Results

No significant difference was noted in ICP or ICP/MAP in response to cavernous nerve electrostimulation between the 3 groups at 2.5, 5, and 7.5 V (P > .05 for all voltages). PD animals developed tunical and subtunical areas of fibrosis with a significant upregulation of collagen III protein. The collagen III/I ratio was higher in the PD (4.6 ± 0.92) group compared with sham (0.66 ± 0.18) and PD-hADSC (0.86 ± 0.06) groups (P < .05) These fibrotic changes were prevented when treated with hADSCs. Compared with PD rats, PD-hADSC rats demonstrated a decreased expression of several fibrosis-related genes.

Conclusion

Injection of hADSCs reduces collagen III expression in a rat model of chronic PD.

A Comparative Study Between 2 Different Grafts Used as Patches After Plaque Incision and Inflatable Penile Prosthesis Implantation for End-Stage Peyronie's Disease

BACKGROUND

Although many grafts have been used for plaque incision with grafting (PIG) and penile prosthesis (PP) implantation, there is no evidence that favors 1 specific graft over another.

AIM

To compare fibrin-coated collagen fleece (TachoSil; Baxter International, Deerfield, IL, USA) with porcine small intestinal submucosa (SIS; Cook Biotech, West Lafayette, IN, USA) as grafts.

METHODS

From January 2007 to January 2015, 60 non-randomized consecutive patients affected by end-stage Peyronie disease underwent PIG and PP implantation (AMS 700CX; Boston Scientific, Marlborough, MA, USA). All patients underwent preoperative penile dynamic duplex ultrasound. All procedures were performed by the same surgeon. Patients were divided in 2 different groups according to the graft used to cover the albuginea defect. SIS was used for grafting in 34 patients (group A) and TachoSil was used in 26 patients (group B).

OUTCOMES

Overall hospital stay, operative time, 5-point Likert hematoma scale, visual analog scale, incidence of postoperative complications, and PP mechanical failure were selected as outcome measures. Functional outcomes were assessed through validated questionnaires (International Index of Erectile Function, Erectile Dysfunction Inventory of Treatment Satisfaction, and Sexual Encounter Profile questions 2 and 3) preoperatively and 3, 6, and 12 months postoperatively.

RESULTS

The patients' median age was 63 years. No statistically significant differences were detected between groups for age and type and degree of curvature (median = 65°). Average follow-up was 35 months. No major intraoperative complications were reported. The average operative time was 145 minutes for group A and 120 minutes for group B. No statistically significant differences between groups were detected for postoperative complications. Only 3 patients developed a major postoperative complication requiring a 2nd surgical intervention: 1 patient in group A for mechanic failure and 1 patient in group A and 1 in group B for inflatable PP infection. Multivariate statistical analysis showed no significant difference for all variables analyzed between the 2 groups, except for operative time, which was significantly shorter for group B.

CLINICAL IMPLICATIONS

TachoSil could represent a valuable option for grafting, considering its advantages in operative time and cost compared with SIS.

STRENGTHS AND LIMITATIONS

Long-term follow-up represents a strength factor. Main limitations are the non-randomized nature of the study and the small number of patients.

CONCLUSIONS

TachoSil seems to represent an effective solution for grafting after PIG and PP implantation. However, additional studies are warranted to confirm our results. Falcone M, Preto M, Ceruti C, et al.

Objective measurements of the penile angulation are significantly different than self-estimated magnitude among patients with penile curvature

Introduction:

The study was aimed to assess the presence of actual differences between the objective and the perceived magnitude of a curvature between patients affected by Peyronie's disease (PD) and congenital penile curvature (CPC).

Materials and Methods:

Wee analysed a cohort of 88 consecutive patients seeking medi- cal help for either CPC or PD. All patients were invited to provide a self-made drawing of their penis in erection in order to obtain self-provided description of the deformity. An objective measurement of the deformity was also performed drawing two intersecting lines through the center of the distal and proximal straight section of the penile shaft.

Results:

Our findings showed significant differences between patient self-estimation and the objective measurements of the penile angulation performed by trained experts, with only 32% of patients correctly assessing their own curvature. Overall, patients tended to overestimate (56%) their degree of curvature, but the results are different in patients with PD than those with CPC. In the 60 men (68%) who did not accurately assess their curvature, PD patients generally overestimated their curvature versus CPC patients (67% vs 16%). On the contrary CPC patients underestimated their curvature compared to PD (42% vs. 4%).

Conclusion:

In order to improve patients' satisfaction rates, the surgeon needs to take into consideration the patient's perception of the deformity when planning the type of surgical correction.

The management of the acute ischemic priapism: A state of the art review

OBJECTIVE

To review the current literature on early penile prosthesis implantation in patients with refractory ischemic priapism (IP).

ACQUISITION OF EVIDENCE

A systematic search for the terms "penile prosthesis", "priapism", "impotence", "fibrosis", "downsized prosthesis cylinders", and "patient satisfaction" has been carried out in PubMed, EMBASE, Cochrane, SCOPUS and Science Citation Index databases.

SYNTHESIS OF EVIDENCE

Cavernosal tissue damage in IP is time related. Conservative measures and aspiration with or without intracorporeal instillation of α-adrenergic agonists are usually successful in the early stages. Shunt surgery in patients remains debatable, as the lack of response to aspiration and instillation of α-adrenergic agonists indicates that irreversible changes in the cavernosal smooth muscle are likely to have already occurred. Immediate penile prosthesis implantation in patients with refractory IP settles the priapic episode, maintains the long term rigidity necessary to engage in penetrative sexual intercourse and prevents the otherwise inevitable penile shortening. Although complication rates after penile prosthesis implantation in acute priapism are higher than in virgin cases, they are still lower than after implantation in patients with severe corporal fibrosis due to chronic priapism. Regardless of the complication rates, penile prosthesis implantation in refractory IP should be preferred as it allows the preservation of penile length, which is one of the main factors influencing postoperative patient's satisfaction following surgery.

Outcomes of inflatable penile prosthesis insertion in 247 patients completing female to male gender reassignment surgery

OBJECTIVES

To assess the oucomes of penile prosthesis (PP) implantation after total phallic reconstruction secondary to gender dysphoria.

PATIENTS AND METHODS

We conducted a retrospective single-centre analysis of 247 consecutive patients. The recruitment period was January 2001 to October 2015. A total of 328 inflatable PPs were implanted. A two-staged inflatable PP implantation was carried out. As a first step, an extraperitoneal reservoir placement was performed simultaneously with the glans sculpture and the insertion of a single large testicular prosthesis into the labia majora. Subsequently, cylinder(s) and pump placement was performed. A Dacron envelope was fitted around the proximal and distal aspect of the cylinder(s) to anchor the device to the pubic bone and to prevent apical protrusion. The outcomes measured were postoperative complications, eventual need for revision surgery, and long-term survival of the implants. Patient and partner satisfaction rates were extrapolated from the administered non-validated questionnaires. The data were analysed using non-parametric tests, multivariate logistic regression analysis, and a Kaplan-Meier survival curve.

RESULTS

The mean follow-up was 20 months. In all, 88% of patients were satisfied with the result, although only 77% used their device for sexual intercourse. The overall 5-year device survival was 78%, with no one device being superior. Device infection occurred in 8.5% of patients with an overall revision rate of 43%. According to the multivariate logistic regression analysis, only type of phalloplasty significantly affected the infection risk (P = 0.013).

CONCLUSIONS

Implantation of a PP into a neophallus is a complex procedure but yields high satisfaction rates. Nevertheless, complication rates are high and patients must be warned that multiple revisions will be necessary throughout their lifetime.

Current Management of Penile Fracture: An Up-to-Date Systematic Review

INTRODUCTION

Because of the low incidence of penile fracture, many aspects of the diagnostic process and of the surgical and functional outcomes are rarely reported.

AIM

To systematically review the current literature on the surgical management of penile fracture, focusing on etiology, diagnosis, functional outcomes, and postoperative complications.

METHODS

The present review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) declaration standards for systematic reviews. A systematic search for the terms penile fracture, fracture of penis, trauma of penis, rupture of corpora cavernosa, and immediate management of penile fracture was been carried out in the PubMed, EMBASE, Cochrane, SCOPUS, and Science Citation Index databases.

MAIN OUTCOME MEASURES

Etiology of penile fracture, clinical presentation, types of radiologic investigations and their accuracy, surgical approach, suture material used for tunica repair, timing of surgical exploration, intraoperative findings, surgical complications, and functional outcomes.

RESULTS

The total number of patients analyzed was 438, and the patients' an average age was 36 years. The most frequent reported cause of penile fracture was sexual intercourse (80% of cases). The most common finding at examination was a penile hematoma (97.5%). Although operator dependent, in experienced hands, ultrasonography was found to be a useful tool in confirming the location of the albuginea tear and identifying the presence of any concomitant urethral injury, helping the surgeon to choose the best surgical approach. Early surgical repair of a penile fracture was found to be a safe procedure, although long-term complications are not uncommon. Tertiary referral centers that managed a larger number of cases seemed to obtain more satisfactory long-term results with a significantly smaller number of complications.

CONCLUSION

A low incidence of postoperative complications and full satisfactory functional outcomes are reported when early repair is performed in high-volume centers.

Management of refractory ischemic priapism: current perspectives

OBJECTIVES

The aim of the present manuscript is to review the current literature on priapism, focusing on the state-of-the-art knowledge of both the diagnosis and the treatment of the refractory ischemic priapism (IP).

METHODS

Pubmed and EMBASE search engines were used to search for words "priapism", "refractory priapism", "penile prosthesis", "diagnosis priapism", "priapism treatment", "penile fibrosis", "priapism therapy". All the studies were carefully examined by the authors and then included in the review.

RESULTS

First-line treatment involves ejaculation, physical exercise and cold shower followed by corporal blood aspiration and injection of α-adrenoceptor agonists. Subsequently, a distal or proximal shunt may be considered. If none of the treatment is effective or the priapism episode lasts >48 hours penile prosthesis implantation could be the only option to solve the priapism and treat the ongoing erectile dysfunction.

CONCLUSION

The management of IP is to achieve detumescence of persistent penile erection and to preserve erectile function after resolution of the priapic episode. On the other hand, penile fibrosis and following shortening should be prevented. Early penile prosthesis implantation in patients with refractory IP is able to solve both the priapic episode and prevent the otherwise certain penile shortening. Penile prosthesis implantation is the actual gold standard of care in cases of refractory IP.

Sleep disorders in patients with erectile dysfunction

OBJECTIVE

To assess the prevalence of obstructive sleep apnoea (OSA) in men presenting with erectile dysfunction (ED) at a single centre.

PATIENTS AND METHODS

All men attending a specialised andrology outpatient department with a new diagnosis of ED were included in this prospective study. All patients completed three questionnaires: the International Index of Erectile Function (IIEF) and two sleep questionnaires [the Obstructive Sleep Apnoea Screening questionnaire and the Insomnia Severity Index (ISI)]. Their ED management was subsequently undertaken in accordance with local and European guidelines. An OSA diagnosis was made based on a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire and those patients were referred for specialist management.

RESULTS

Between February and September 2016, 129 patients with ED completed the study questionnaires. In all, 71 patients (55%) had a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire, indicating a need for specialist sleep referral. Men who scored ≥3 on the Obstructive Sleep Apnoea Screening questionnaire were significantly older (61.4 vs 46.5 years; P < 0.001) and had a significantly higher body mass index (29.4 vs 26.7 kg/m² ; P < 0.001) when compared to the control group (OSA score of <3). The sleep apnoea group (OSA score of ≥3) had significantly worse IIEF-ED scores (6.2 vs 9.1; P = 0.018) and ISI scores (7.9 vs 5.5; P = 0.061).

CONCLUSION

Men presenting to the andrology clinic with ED are at significant risk of having undiagnosed sleep disorders. This has serious adverse health consequences, as well as being associated with potential dangers at work and travel. The patient compliance was high with 78% completing all three questionnaires. It is feasible to screen this population for sleep disturbance and this should be part of the ED assessment.

Total phallic reconstruction after penile amputation for donkey bite: Case report and review of the literature

There are very few reported cases of traumatic amputation of the male genitalia due to animal bite. The management involves thorough washout of the wounds, debridement, antibiotic prophylaxis, tetanus and rabies immunization followed by immediate reconstruction or primary wound closure with delayed reconstruction, when immediate reconstruction is not feasible. When immediate reconstruction is not feasible, long-term good functional and cosmetic results are still possible in the majority of cases by performing total phallic reconstruction. In particular, it is now possible to fashion a cosmetically acceptable sensate phallus with incorporated neourethra, to allow the patient to void while standing and to ejaculate, and with enough bulk to allow the insertion of a penile prosthesis to guarantee the rigidity necessary to engage in penetrative sexual intercourse.
