A Rare Cause of Autoinflation after Penile Prosthesis Insertion: Case Series and Systematic Review.

BACKGROUND: In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation. AIM: To raise awareness amongst implanters, we describe further cases from our institution and perform a systematic review of the literature to understand the rarity of this phenomenon. METHODS: Patient demographics, management and outcomes were extracted retrospectively. A systematic search of the EMBASE, PubMed and PubMed Central libraries for studies reporting arteriocavernosal fistula mimicking autoinflation since 1946 was performed. OUTCOMES: To identify and report all known cases of high flow priapism and arteriocavernosal fistula presenting as autoinflation of an inflatable penile prosthesis. RESULTS: Four patients in total (median age 56, range 46-60 years) were identified. Catastrophic bleeding (1.8L) occurred during revision surgery for presumed autoinflation in Patient 1 and subsequent ultrasound (US) confirmed a fistula which was embolized. Patient 2 redeveloped autoinflation following revision surgery. Ultrasound confirmed high flow priapism from an arteriocavernosal fistula. Patient 3 underwent penile magnetic resonance imaging (MRI) to investigate autoinflation and residual penile curvature. MRI showed a tumescent penis despite a deflated device and the fistula was embolized successfully. Patient 4 with sleep-related painful erections did not improve following insertion of penile prosthesis. Doppler US identified 2 fistulae that was embolized but with no resolution of symptoms. Subsequent embolization of both common penile arteries were done to control his symptoms. No other publications apart from the published abstract from 2016 reporting patient 1 was found. CLINICAL IMPLICATIONS: If considered prior to revision surgery, the fistula can be managed safely by minimally invasive percutaneous angioembolisation avoiding surgery which can potentially be associated with significant complications. STRENGTHS AND LIMITATIONS: The rarity of this phenomenon was supported by a systematic review. Our study however does present the findings from a small number of patients. CONCLUSION: Damage to the cavernosal artery during inflatable penile prosthesis insertion can create an arteriocavernosal fistula that mimics autoinflation, leading to catastrophic intra-operative bleeding or unnecessary surgery.

The Use of Penile Traction Devices for Peyronie's Disease: Position Statements from the European Society for Sexual Medicine.

INTRODUCTION: Penile traction therapy (PTT) aims to non-surgically reduce curvature, enhance girth, and recover lost length. Available clinical practice guidelines however lack clear recommendations regarding their use. AIM: To present a comprehensive review and recommendation regarding the available evidence to the use of PTT in Peyronie's disease (PD). METHODS: A systematic literature search was performed on Pubmed and Medline for relevant studies from all times until 2019. Studies of PTT (monotherapy and in combination) in patients with PD with any documented degree of curvature and in either the acute or chronic phase of the disease were included. Full texts not published in English language were excluded. MAIN OUTCOMES MEASURES: Several scenarios, including preclinical data have been investigated. For each topic covered evidence was analyzed and expert opinion was stated. RESULTS: The paucity of high-level studies precluded any strong recommendations, however, specific statements on this topic, summarizing the ESSM position, were provided. The available data about the use of PTT in PD are still poor, and the impact of this therapy for the treatment of PD has not been clearly stablished. Available data in the clinical setting are still poor, and the impact of these devices on PD evolution has not been clearly established. CONCLUSION: PTT seems to be a valid treatment option for PD, although there is not enough evidence to give any definitive recommendation in any clinical scenario.

Restoration of the Lost Obscured Coronal Sulcus: A Novel Surgical Technique for Penile Lichen Sclerosus with Severe Preputial Adhesions.

BACKGROUND: Lichen sclerosus (LS) may cause the glans and prepuce to become fused, making a standard circumcision impossible. Most authorities recommend excision of the fused area with glans resurfacing, although partial circumcision is often performed. OBJECTIVE: To evaluate an alternative technique that preserves the fused area and allows a complete circumcision without grafting. DESIGN, SETTING, AND PARTICIPANTS: Over 3 yr (January 2016-March 2018), 28 men (age 28-93 yr; mean 62 yr) underwent the restoration of lost obscured coronal sulcus (ROLOCS) procedure with over 1 yr of follow-up. Complications were reviewed retrospectively with an additional survey. SURGICAL PROCEDURE: The shaft skin is incised at the corona. Dartos is divided, which allows antegrade dissection just outside the fused glans membrane. The foreskin is removed and shaft skin sutured to dartos below the corona. MEASUREMENTS: Postoperative pain, aesthetic satisfaction, sexual enjoyment, glans sensation, and urinary symptoms were measured. RESULTS AND LIMITATIONS: There were no major complications. In all cases, the coronal sulcus was restored and the glans skin became soft without skin grafting. All were satisfied with the aesthetics. Of the patients, <70% experienced mild to low-moderate pain; 55% and 25% had, respectively, improved or reduced glans sensation; and 40% reported improved enjoyment of sex. Histology showed LS in all cases with squamous cell carcinoma in four, including three out of five patients who had previously undergone partial circumcision. Although this is the largest series reported yet, the numbers were too small for a meaningful statistical analysis. CONCLUSIONS: The ROLOCS operation offers an aesthetically superior alternative to partial circumcision and is easier to perform with less morbidity than skin grafting. PATIENT SUMMARY: The restoration of lost obscured coronal sulcus (ROLOCS) procedure provides an alternative to partial circumcision or circumcision with skin grafting when the foreskin is welded to the head of the penis (glans) due to lichen sclerosus. It produces a good cosmetic result, but the glans can be sore until it heals.

Radiofrequency-Based Devices for Female Genito-Urinary Indications: Position Statements From the European Society of Sexual Medicine.

INTRODUCTION: Radiofrequency (RF)-based treatment has been introduced as an esthetic alternative treatment for various medical indications without the scientific backup of a satisfactory body of evidence. Furthermore, the United States Food and Drug Administration issued a warning regarding the safety of energy-based technologies for indications such as vaginal "rejuvenation," cosmetic vaginal treatment, vaginal conditions related to menopause, and symptoms of urinary incontinence and sexual function on July 30, 2018. AIM: To perform a thorough review of the existing literature regarding RF-based vaginal devices for the treatment of female genitourinary indications and summarize the evidence available in a few short statements. METHODS: A thorough review of the literature regarding RF treatments for gynecological indications was performed based on several databases. Studies that included at least 15 patients were eligible for analysis. MAIN OUTCOME MEASURE: Efficacy of RF devices for different genitourinary indications. RESULTS: Although a high level of heterogeneity of studies poses a serious challenge, the committee reached a decision on several statements related to the use of RF-based devices for genitourinary indications. CLINICAL IMPLICATIONS: RF-based vaginal treatments have not been studied thoroughly enough in order to establish decisive recommendations regarding their safety and efficacy. STRENGTH & LIMITATIONS: These position statements have been established by a group of experts. The lack of strong evidence makes it difficult to give decisive recommendations. CONCLUSIONS: Further randomized controlled trials with proper methodology and design are required to establish both benefits and possible harm these treatments may have in both short and long term for all the different indications studied.

Laser-Based Devices for Female Genitourinary Indications: Position Statements From the European Society for Sexual Medicine (ESSM).

BACKGROUND: Laser-based technologies have been commercially marketed as "wonder treatments" without a sufficient and adequate body of evidence. In addition, on July 30, 2018, the U.S. Food and Drug Administration issued a warning regarding the safety of the use of laser-based devices for the following indications: vaginal "rejuvenation" or cosmetic vaginal procedures, vaginal conditions and symptoms related to menopause, urinary incontinence, and sexual function. AIM: To perform a thorough review of the available literature regarding laser-based vaginal devices for the treatment of female genitourinary indications and summarize the results in several short statements according to the level of evidence. METHODS: A comprehensive review of the literature regarding laser treatments for gynecological indications was performed based on several databases. Eligible were studies that included at least 15 patients. OUTCOMES: Several aspects, including preclinical data, have been investigated. For each topic covered, data on laser-based devices were analyzed. RESULTS: Despite the high heterogeneity of studies and its limitations, the committee released several statements regarding the use of laser-based devices for genitourinary indications. CLINICAL IMPLICATIONS: Available data in the clinical setting are still poor, and the impact of these technologies on vaginal symptoms and signs has not been clearly established. STRENGTHS & LIMITATIONS: All studies have been evaluated by a panel of experts providing recommendations for clinical practice. CONCLUSION: It is too early in the evolution and research of laser-based devices to make decisive recommendations regarding vaginal treatments. There is grave need to carry out randomized controlled trials with proper design for safety reasons, possible harm, and short-/long-term benefits for the different indications studied.

Floppy Glans-Classification, Diagnosis and Treatment.

INTRODUCTION: Glans hypermobility presents a rarely observed complication of penile prosthesis implantation. It may result in patient dissatisfaction because of painful intercourse, difficulties during penetrative sex, and a poor cosmetic result. This problem may prevent the patient from using an otherwise fully functional implant. AIM: To summarize current knowledge, clarify terminology, and review treatment options of multifaceted diagnosis of floppy glans. METHODS: Analysis of published literature and experience of authors' institution. MAIN OUTCOME MEASURE: We reviewed publications that outlined incidence, pathophysiology, diagnostics, and management strategies of floppy glans phenomenon. RESULTS: Floppy glans phenomenon can result from the soft glans, incorrect position, or size of the implant cylinders or the anatomy of the glans. A careful physical examination with a fully inflated implant will indicate the direction of the droop and can be very helpful in distinguishing the underlying cause of the deformity. In ambiguous cases obtaining a correct diagnosis will often involve imaging-magnetic resonance imaging or penile ultrasound scanning of the inflated device. Cooperation with an experienced uroradiologist is invaluable in such cases. The glanspexy procedure should be performed according to the surgeon's experience and preference. CONCLUSIONS: Understanding the different glans abnormalities and unified terminology is crucial for optimization of the treatment. Medical therapy can always be tried before revision surgery, as long as it is safe for the patient and function of the implant. The accuracy of the position and size of the implant should always be thoroughly assessed before a diagnosis of the real glans hypermobility is made and treatment provided.

Which patients with ischaemic priapism require further investigation for malignancy?

Ischaemic priapism (IP) is characterised by a persistent, painful penile erection lasting for >4 h. Many causes of IP have been identified including haematological dyscrasias (particularly, sickle cell disease), drugs and rarely malignancy. There are also a large proportion of men, in which no aetiology is identified. Identification of men at risk for malignancy provides a diagnostic challenge to the clinicians looking after these patients. All cases of IP between 2007 and 2017 at a single tertiary andrology unit were identified. The case notes and electronic records of these patients were reviewed to identify cases of malignant priapism. Men with idiopathic IP were used as a control group for comparative statistics. In total, 412 men with IP were identified, 202 of which had idiopathic IP. Within this group, the prevalence of malignant priapism was 3.5% (n = 11). MP secondary to local invasion or penile metastases occurred in seven of the 11 men (bladder × 3, prostate, lung, urethral and chondrosarcoma of the pelvis). MP secondary to haematological malignancy occurred in the remaining four (chronic myeloid leukaemia × 2, chronic lymphocytic leukaemia, and myelodysplasia). IP was the initial presentation of malignancy in seven of the patients (64%). An abnormally low haemoglobin value (reference range 130-180 g/dl) was found in 82% (n = 9) of the men with MP. The mean haemoglobin value in men with MP was 109.64 ± 20.30 g/dl compared to the control of 131.87 ± g/dl. This difference was considered highly significant p = 0.0046. Men with MP also appear to have a very poor prognosis with an 18-month mortality of 64% (n = 7). Malignancy is a rare and important cause of IP. A low haemoglobin is a predictor of malignancy and warrants further investigation in IP.

Evaluation of the role of downregulation of SNF5/INI1 core subunit of SWI/SNF complex in clear cell renal cell carcinoma development.

Clear cell renal cell carcinoma (ccRCC) is characterized by stabilization of hypoxia-inducible factor (HIF1), and mutations in von Hippel-Lindau (VHL) gene. Additionally, in about 40% of ccRCC cases the mutation in PBRM1 (POLYBROMO1) gene coding for a non-core subunit of SWI/SNF chromatin remodeling complex was found suggesting potential impairment of this complex function in ccRCC. In this study we assessed the extent to which the core SWI/SNF complex subunit - INI1 (hSNF5/SMARCB1) is affected in ccRCC and whether it has any consequences on the development of this type of cancer. The evaluation of INI1 protein level in samples from 50 patients with diagnosed ccRCC, including three displaying rhabdoid features, showed the INI1 positive staining in rhabdoid cells while the conventional ccRCC cells exhibited reduced INI1 level. This indicated the rhabdoid component of ccRCC as distinct from other known rhabdoid tumors. The reduced INI1 protein level observed in all conventional ccRCC cases used in this study correlated with decreased SMARCB1 gene expression at the transcript level. Consistently, the overexpression of INI1 protein in A498 ccRCC cell line resulted in the elevation of endogenous SMARCB1 transcript level indicating that the INI1-dependent regulatory feedback loop controlling expression of this gene is affected in ccRCC Moreover, the set of INI1 target genes including i.e. CXCL12/CXCR7/CXCR4 chemokine axis was identified to be affected in ccRCC. In summary, we demonstrated that the inactivation of INI1 may be of high importance for ccRCC development and aggressiveness.

Primary dorsal buccal mucosa graft urethroplasty for anterior urethral strictures in patients with lichen sclerosus.

PURPOSE: To report our ongoing experience with dorsal buccal mucosa graft (BMG) urethroplasty for the primary repair of anterior urethral strictures in patients with lichen sclerosus (LS). PATIENTS AND METHODS: A total of 32 men with LS underwent BMG urethroplasty from January 2010 to September 2012. In 27 patients, stricture was limited to the penile urethra, while in five patients, both bulbar and penile urethra were involved. In these five patients, the entire anterior urethra was replaced with BMG. In nine (28.1%) younger patients (mean age 38.2 years, range 33-45), with adverse local conditions and significant scarring, two-stage repair was done. The paired t test was performed on preoperative and postoperative Qmax as well as on preoperative and postoperative post-void residual urine volume, and the Fisher exact test was used to assess success between treatment groups. The chi-squared test was used to compare categorical data. RESULTS: The overall success rate was 90.6%. Complications occurred in 9.4% of the patients (3 of 32) including hematoma in two patients and fistula in one patient. In this cohort of patients, mean preoperative Qmax was 6.2 ml per second (range 2.6-10.2) versus 18.2 (range 15.8-21.2) postoperatively (at 9 months), which was statistically significant (p < 0.002). Also, mean preoperative post-void residual urine volume was 110 ml (range 75-180) versus 19 ml (range 10-40) postoperatively at 9 months, which was statistically significant (p < 0.004). CONCLUSION: Buccal mucosa is the most reliable graft for repairing anterior urethral strictures in patients with LS. Minimal complications are observed, even in cases of long stenosis completely afflicting anterior urethra.

Phospholipid composition and electric charge in healthy and cancerous parts of human kidneys.

Phospholipids are ubiquitous in nature and are essential for the lipid bilayer of cell membranes. Their structural and functional properties are pivotal for the survival of the cell. In this study the phospholipids of healthy and cancerous human renal tissues from the same patients are compared with special reference to the electric charge of the membrane. A simple and highly effective normal-phase method is described for analyzing phospholipids content. This work is focused on changes of phospholipids content (PtdIns, phosphatidylinositol; PtdSer, phosphatidylserine; PtdEtn, phosphatidylethanoloamine; PtdCho, phosphatidylcholine) in cell membranes of renal cancer of pT1 stage, G2 grade, without metastasis. Surface charge density of healthy and cancerous human renal tissues was measured by electrophoresis. The measurements were carried out at various pH of solution. Depending on the surface charge density as a function of pH, acidic (C(TA)) and basic (C(TB)) functional group concentrations and their average association constants with hydrogen (K(AH)) or hydroxyl (K(BOH)) ions were evaluated. The process of cancer transformation was accompanied by an increase in total amount of phospholipids as well as an increase in C(TA) and K(BOH), whereas K(AH) and C(TB) were decreased compared with unchanged tumor cells.
