Extraperitoneal robot-assisted radical prostatectomy by the da Vinci and Versius System: first comparative analysis.

BACKGROUND: Robotic-assisted surgery (particularly with the da Vinci Surgical System) has revolutionized urological interventions. The advent of the Versius Surgical System introduces a compelling alternative. This study compares outcomes of extraperitoneal robot-assisted radical prostatectomy (eRARP) using da Vinci and Versius, presenting the largest case series to date. METHODS: A retrospective analysis of 106 consecutive patients undergoing eRARP (July 2021-July 2023) with da Vinci and Versius. Surgical techniques involved extraperitoneal approaches, with a single surgeon ensuring consistency. Baseline characteristics, perioperative outcomes, and pathology results were analyzed. RESULTS: Baseline characteristics were comparable between da Vinci and Versius groups. While no significant differences were observed in overall operative time, estimated blood loss, and length of hospital stay, variations were noted in pelvic lymphadenectomy rates and nerve-sparing procedures. Pathology results revealed no significant disparities in International Society of Urological Pathology (ISUP) grades and positive surgical margins. However, a notable difference emerged in pathological N stage, with Versius showing a higher percentage of positive lymph nodes. CONCLUSIONS: This study provides a comprehensive comparative analysis of da Vinci and Versius in eRARP, representing the largest case series to date. While overall outcomes were similar, nuances in lymphadenectomy rates and Pathological N stage merit attention. Ongoing research and longer-term follow-up will refine our understanding, guiding urological surgeons in optimal robotic system selection.

Assessing in-hospital morbidity after urethroplasty using the European Association of Urology Quality Criteria for standardized reporting.

PURPOSE: To conduct a rigorous assessment of in-hospital morbidity after urethroplasty according with the European Association of Urology (EAU) guidelines for complication reporting. METHODS: We retrospectively (2015-2019) identified 469 consecutive patients receiving urethroplasty (e.g. bulbar urethroplasty with grafts, penile urethroplasty with/without grafts/flaps, Johanson, de novo or revision perineostomy, end-to-end anastomosis, meatoplasty and/or meatotomy) at our tertiary care institution. Complications were graded with Clavien-Dindo score and Comprehensive Complication Index (CCI). Complications were classified in: bleeding no gastrointestinal, cardiac, gastrointestinal, genitourinary, infectious, neurological, oral, wound, miscellaneous, and pulmonary. Logistic regression tested for predictors of in-hospital complications and prolonged hospitalization (> 75th percentile). Kaplan-Meier and Cox regression investigated the effect of complications on failure after urethroplasty. RESULTS: Overall, 161 (34.3%) patients experienced at least one complication. Of those, 47 (10%) experienced two or more complications and 59 (12.6%) experienced at least one Clavien-Dindo ≥ II complication. Only two patients had Clavien-Dindo III complications. Infectious was the most frequent complication, and de novo or revision perineostomy was associated with the highest rate of complications. The occurrence of any complications, as well as complication with Clavien-Dindo ≥ II were associated with prolonged hospitalizations, but not with higher rates of post-urethroplasty failure. CONCLUSIONS: Complications after urethroplasty were common events, but rarely with severe sequelae. Infectious were the most common complications and perineostomy was the type of urethroplasty with the highest rate of complications. The application of the EAU recommendations allowed the identifications of a higher number of complications after urethroplasty if compared with previous reports based on unsupervised chart review.

Patient-reported outcomes for typical single cheek harvesting vs atypical lingual, labial or bilateral cheeks harvesting: a single-center analysis of more than 800 patients.

PURPOSE: The optimal harvesting site for oral grafting in patients with urethral strictures remain controversial, with no study investigating morbidity on large scale. We aimed to compare typical single cheek harvesting vs atypical lingual, labial or bilateral cheeks harvesting in terms of complications and patient-reported outcomes. METHODS: Within 827 patients treated at our referral center with oral graft urethroplasty, we compared typical vs atypical harvesting techniques. A self-administered, semiquantitative, non-validated questionnaire assessed early (10 days) and late (4 months) postoperative complications and patient-reported outcomes. A semiquantitative score was calculated according to patient responses, and it was used to assess early (6 questions) and late (13 questions) patient dissatisfaction status. Patients were defined early and/or late dissatisfied when they scored ≥ 7 and ≥ 10 at the early or late questionnaires, respectively. RESULTS: Between 1998 and 2019, our patients predominantly received typical single cheek harvesting (89% vs 11%), with + 1.5% increase rate per year (p < 0.001). Early and late dissatisfied patients were, respectively, 170 (23%) vs 39 (44%) and 59 (8%) vs 16 (18%) in the typical vs atypical groups. Atypical harvesting was associated with higher rates of early (Odds ratio [OR]: 2.34; 95% Confidence interval [CI] 1.44-3.75; p = 0.001) and late (OR: 2.37; 95%CI 1.22-4.42; p = 0.008) postoperative dissatisfaction. CONCLUSIONS: Typical single cheek harvesting was the preferred surgical option at our center and it was associated with negligible early and late rates of complications and patient's dissatisfaction. Conversely, atypical lingual, labial or bilateral cheeks harvesting was associated with higher complications and frequent patient dissatisfaction.

Risk calculator for prediction of treatment-related urethroplasty failure in patients with penile urethral strictures.

PURPOSE: To design a dedicated risk calculator for patients with penile urethra stricture who are scheduled to urethroplasty that might be used to counsel patients according to their pre-operative risk of failure. METHODS: Patients treated with penile urethroplasty at our center (1994-2018) were included in the study. Patients received 1-stage or staged penile urethroplasty. Patients with failed hypospadias repair, lichen sclerosus or incomplete clinical records were excluded. Treatment failure was defined as any required postoperative instrumentation, including dilation. Univariable Cox regression identified predictors of post-operative treatment failure and Kaplan-Meier analysis plotted the failure-free survival rates according to such predictors. Multivariable Cox regression-based risk calculator was generated to predict the risk of treatment failure at 10 years after surgery. RESULTS: 261 patients met the inclusion criteria. Median follow-up was 113 months. Out of 216 patients, 201 (77%) were classified as success and 60 (23%) failures. Former smoker (hazard ratio [HR] 2.12, p = 0.025), instrumentation-derived stricture (HR 2.55, p = 0.006), and use of grafts (HR 1.83, p = 0.037) were predictors of treatment failure. Model-derived probabilities showed that the 10-year risk of treatment failure varied from 5.8 to 41.1% according to patient's characteristics. CONCLUSIONS: Long-term prognosis in patients who underwent penile urethroplasty is uncertain. To date, our risk-calculator represents the first tool that might help physicians to predict the risk of treatment failure at 10 years. According to our model, such risk is largely influenced by the etiology of the stricture, the use of graft, and patient's smoking habits.

Surgical treatment of bulbar urethral strictures: tips and tricks.

The surgical treatment of bulbar urethral strictures is still one of the most challenging reconstructive surgery problems. Bulbar urethral strictures are usually categorized as traumatic and non-traumatic strictures depending on the aetiology. The traumatic strictures are caused by trauma and they determine disruption of the urethra with obliteration of the urethral lumen, ending with fibrotic gaps between the urethral ends. Differently, the non-traumatic urethral strictures are mainly caused by catheterization, instrumentation, and infection, or they can also be idiopathic. They are usually asso-ciated with spongiofibrosis of the segment of the urethra that has been involved. Worldwide, two different surgical approaches are currently adopted for bulbar urethral repair: transecting techniques with end-to-end anastomosis and non-transecting techniques followed by grafting. Traumatic obliterated strictures require transection of the urethra allowing complete removal of the fibrotic tissue that involves the urethral ends. Conversely, non-traumatic, non-obliterated urethral strictures require augmentation of the urethral plate using oral mucosa grafts. Nowadays, it is still difficult to choose the correct surgical management for non-obliterated bulbar stricture repair. Indeed, different surgical techniques have been proposed (pedicled flap vs free graft, dorsal vs ventral placement of the graft, non-transecting technique using or non-using free graft, etc.) but none emerged as the best solution since all techniques have showed similar success and complication rates. Consequently, the final choice is still based on surgeon's preferences and patient's characteristics. Within the current manuscript, we like to present some of our tips and tricks that we developed along our prolonged surgical experience on the treatment of bulbar urethral strictures. These might be of interest for surgeons that approach this complex surgery. Moreover, our suggestions want to be useful regardless the type of chosen technique being adaptable for different scenario.

Focus on Internal Urethrotomy as Primary Treatment for Untreated Bulbar Urethral Strictures: Results from a Multivariable Analysis.

BACKGROUND: The use of internal urethrotomy for treatment of urethral stricture remains a controversial topic in urology. OBJECTIVE: To investigate outcomes and predictors of failure for internal urethrotomy as primary treatment for untreated bulbar urethral strictures. DESIGN, SETTING, AND PARTICIPANTS: We performed a retrospective analysis of patients who underwent internal urethrotomy. Patients with bulbar urethral stricture who did not receive any previous treatment were included. Patients with traumatic, penile or posterior urethral strictures, lichen sclerosus, failed hypospadias repair, or stricture length >4cm were excluded. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was treatment failure. Kaplan-Meyer plots were used to depict treatment failure-free survival. Univariate and multivariable Cox regression analyses were used to test the association between predictors (age, body mass index, diabetes, history of smoking, etiology, stenosis type and length, preoperative maximum flow [pQmax]) and treatment failure. RESULTS AND LIMITATIONS: Overall, 136 patients were included. The median stricture length was 2cm. Median follow-up was 55 mo. At 5-yr follow-up the failure-free survival rate was 57%. On univariate analysis, diabetes, nonidiopathic etiology, stricture length of 3-4cm, and pQmax were significantly associated with treatment failure. These predictors were included in a multivariable analysis, in which pQmax was the only significant predictor of treatment failure. CONCLUSIONS: Failure of internal urethrotomy for untreated bulbar urethral strictures greatly depends on pQmax flow at uroflowmetry. Patients with pQmax >8ml/s have a high probability of success, while patients with pQmax <5ml/s have a low probability of success. PATIENT SUMMARY: The use of internal urethrotomy in patients with an untreated bulbar urethral stricture should only be considered in selected cases.

Prevalence and surgical management of pubic hypertrophy in hypospadias patients: results from a high-volume surgeon.

INTRODUCTION: Pubic hypertrophy, defined as an abnormal and abundant round mass of fatty tissue located over the pubic symphysis, is frequently underestimated in patients with hypospadias. We examined the prevalence of this condition, as well as the outcomes associated with its surgical treatment. MATERIAL AND METHODS: Within 266 hypospadias patients treated at our clinic, we assessed the prevalence of pubic hypertrophy, and we schematically described the surgical steps of pubic lipectomy. Multivariable logistic regression (MLR) tested for predictors of pubic hypertrophy. Finally, separate MLRs tested for predictors of fistula and any complications after pubic lipectomy. RESULTS: Of 266 hypospadias patients, 100 (37.6%) presented pubic hypertrophy and underwent pubic lipectomy. Patients with pubic hypertrophy more frequently had proximal hypospadias (44 vs. 7.8%), disorders of sex development (DSD) (10 vs. 0.6%), cryptorchidism (12 vs. 2.4%), and moderate (30°-60°) or severe (>60°) penile curvature (33 vs. 4.2%). In MLR, the loca-tion of urethral meatus (proximal, Odds ratio [OR]: 10.1, p<0.001) was the only signifi cant pre-dictor of pubic hypertrophy. Finally, pubic lipectomy was not associated with increased risk of fi stula (OR: 1.12, p=0.7) or any complications (OR: 1.37, 95% CI: 0.64-2.88, p=0.4) after multi-variable adjustment. CONCLUSIONS: One out of three hypospadias patients, referred to our center, presented pubic hypertrophy and received pubic lipectomy. This rate was higher in patients with proximal hypospadias suggesting a correlation between pubic hypertrophy and severity of hypospadias. Noteworthy, pubic lipectomy was not associated with increased risk of fistula or any complications.

A "real life" investigation on the prescriptive habits among Italian andrologists: The "CONSER" survey from Italian Society of Andrology (SIA) on Sildenafil oral film.

Even if oral type 5 phosphodiesterase inhibitors (PDE5i) seem an effective treatment for erectile dysfunction (ED), the drop-out is high among patients. For this reason, pharmaceutical companies are encouraged to develop new administration routes, such as the orally disintegrating film. The aim of this study was to analyse the prescription habit of Italian andrologists affiliated to Italian Society of Andrology (SIA) in the era of new oro-dispersible formulation of sildenafil. A 12-items dedicated questionnaire has been distributed to 77 urologists andrologists. As a result of the questionnaire, sildenafil is still the preferred drug of Italian andrologists as it is considered the safest and the most effective. It combines the speed of action and the discretion of the intake that are very important issues for the adherence to the treatment according to the Italian sample. Physicians have also reported the positive feedback of the patients taking sildenafil film as they consider the oro-dispersible formulation either comparable or superior to the old tablet. In conclusion this new formulation has given a new life to an old molecule like sildenafil, and Italian andrologists considered this new pharmaceutical formulation as a good tool to improve the patient's adherence to the treatment and quality of life.

Repair of sphincter urethral strictures preserving urinary continence: surgical technique and outcomes.

INTRODUCTION: Repair of post-TURP sphincter urethral strictures represents challenging problem, due to the risk of urinary incontinence after the repair. We described a surgical technique we use to repair these strictures preserving urinary continence in patients with incompetent bladder neck. MATERIALS AND METHODS: An observational, retrospective, study was conducted to include patients with post-TURP urethral strictures in the area of distal sphincter. We included only patients with complete clinical data and follow-up who previously underwent TURP or HOLEP or TUIP, and subsequently developed proximal bulbar urethral strictures close to the membranous urethra and the related distal urethral sphincter. Patients were included, if they were fully continent after TURP or other procedures to treat BPH. The primary outcome of the study was treatment failure, defined as the need for any post-operative instrumentation. Secondary outcome was post-urethroplasty urinary continence. Patients showing stricture recurrence or post-operative incontinence were classified as failure. RESULTS: Overall, 69 patients were included in the study. Median patient's age was 67 years; median stricture length was 4 cm. Thirty-tree patients (47.8%) underwent previous urethrotomy. Median follow-up was 52 months. Out of 69 patients, 55 (79.7%) were classified as success and 14 (20.3%) as failure. Out of the whole cohort, thus, 11/69 (16%) have a risk of recurrent strictures and 3/69 (4.3%) have incontinence. CONCLUSIONS: The use of modified ventral onlay graft urethroplasty, using particular non-aggressive steps, is a suitable surgical technique for repair of sphincter urethral stricture in patients who underwent BPH transurethral surgery, using different procedures (TURP, HOLEP, TUIP).

Treatments of 1242 bulbar urethral strictures: multivariable statistical analysis of results.

PURPOSE: We investigated the success rate of different surgical techniques for bulbar stricture repair. METHODS: Retrospective study of patients with bulbar urethral strictures treated using different techniques. The primary outcome of the study was to evaluate the overall results of treatment (success vs. failure); the secondary outcome was to evaluate the outcome according to any surgical technique. Cysto-urethrography was performed 1 month following surgery. Patients underwent clinical evaluation, uroflowmetry and residual urine measurement every 6 months for 2 years after surgery and later once on year. When patient showed obstructive symptoms, Qmax < 12 ml/s, the urethrography was repeated. Patients who underwent further treatment for recurrent stricture were classified as failures. A bivariable and multivariable statistical analysis was performed. RESULTS: Overall, 1242 patients were included in the study with mean age 40 years (range 12-84). Median stricture length was 4 cm (range 1-8). The median follow-up was 103 months (range 12-362). Over 1242 patients, 916 (73.8%) were success and 326 (26.2%) failures. Fourteen different surgical techniques showed a success rate ranging from 87.5 to 14.3%. The multivariable analysis showed that stricture length was an independent predictor factors for failure: p < 0.0001 CI 1146-1509. End-end anastomosis and oral mucosa graft urethroplasty are independent predictor factor of success after internal urethrotomy failure. CONCLUSIONS: Our results showed that treatment of bulbar urethral stricture is satisfactory on 73.8% of patients, but with a wide range of success rate (from 14.3 to 87.5%) using different techniques. Oral mucosa is greatly superior to the skin as substitute material.

History and evolution of the use of oral mucosa for urethral reconstruction.

We report here the history and evolution of the use of oral mucosa in reconstructive urethral surgery since it was first used for urethroplasty in 1894. Since that time, many authors have contributed to develop, improve and popularize the use of oral mucosa as a substitute material. Paediatric urologists should be considered pioneers on the use of oral mucosa as they used it to repair primary and failed hypospadias. The use of oral mucosa to repair penile and bulbar urethral strictures was described, for the first time, in 1993. Important evolutions in the technique for harvesting oral mucosa from the cheek were reported in 1996. Today, oral mucosa is considered the gold standard material for any type of anterior urethroplasty in a one- or two-stage repair due to its biological and structural characteristics that make it a highly versatile that is adaptable to any environment required by the reconstructive urethral surgery. As the future approaches, tissue engineering techniques will provide patients with new materials originating from the oral epithelial mucosal cells, which are cultured and expanded into a scaffold. However, the path to reach this ambitious objective is still long and many difficulties must be overcome along the way.

Correlation Between Primary Hypospadias Repair and Subsequent Urethral Strictures in a Series of 408 Adult Patients.

BACKGROUND: The correlation between primary hypospadias repair and subsequent urethral strictures in adults has never been addressed. OBJECTIVE: To evaluate the correlation between the site of primary hypospadias repair and the site of subsequent strictures and to investigate the predictive factors of failure after urethroplasty. DESIGN, SETTING, AND PARTICIPANTS: An observational, retrospective, descriptive study of adult patients with urethral strictures following hypospadias surgery was carried out in a single centre. INTERVENTION: Meatotomy, meatoplasty, end-to-end anastomosis, urethroplasty, perineostomy, urethrotomy, and fistula closure. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We performed correlations between the site of primary hypospadias and the site of subsequent strictures, treatment failure, and patient lack of motivation for definitive treatment. Cross-tables, Kaplan-Meier curves, and logistic or Cox regression were used. RESULTS AND LIMITATIONS: A total of 408 patients, with median follow-up of 96 mo, were included. Concordance between the site of primary hypospadias repair and the site of subsequent strictures was observed. Multivariable analysis revealed that the number of previous operations needed for initial hypospadias repair was not associated with the risk of treatment failure (hazard ratio [HR] 0.96; 95% confidence Interval [CI] 0.88-1.04; p=0.3) or a lack of patient motivation (odds ratio 0.99, 95% CI 0.90-1.10; p=0.9). Length of stenosis (HR 1.38, 95% CI 1.11-1.71; p=0.004) and lichen sclerosus (HR 1.73, 95% CI 1.03-3.25; p=0.035) were associated with a higher risk of treatment failure. Our study is not representative of the entire population of patients with hypospadias repair. CONCLUSIONS: The stricture site is usually consistent with the site of hypospadias. Stricture length, but not the number of previous operations needed for primary hypospadias repair, was associated with the risk of failure. PATIENT SUMMARY: The number of operations needed for hypospadias repair was not associated with failure of subsequent urethroplasty.

A novel composite two-stage urethroplasty for complex penile strictures: A multicenter experience.

INTRODUCTION: Complex penile strictures are usually repaired using a two-stage urethroplasty. Buccal mucosal graft (BMG) placed in the first stage can have a significant contraction rate, which may require a subsequent revision surgery. We describe a composite two-stage penile urethroplasty using BMG for patients of complex penile strictures who have some salvageable urethral plate. METHODS: Within a multi-institutional cohort, 82 patients underwent a two-stage urethroplasty for complex stricture of the penile urethra. Of these 42 patients who underwent our composite two-stage penile urethroplasty using BMG implanted at the second-stage were included. Patients with genital lichen sclerosus or incomplete clinical records were excluded from this study. The primary outcome of the study was to evaluate stricture-free success rate. RESULTS: Of total 42, 4 patients were lost to follow-up. 42% of stricture etiology was failed hypospadias repair. Mean stricture length was 4.5 cm (range 3-8 cm). Seventeen (44.7%) patients had undergone the previous urethroplasty. At a median follow-up of 44 months, of 38 patients, 34 (89.5%) were successful, and 4 (10.5%) had a recurrence. No patient required revision surgery before the second-stage and required redo buccal graft harvesting for subsequent urethroplasty. CONCLUSIONS: The composite two-stage technique in repairing complex penile urethral strictures is a valid and reproducible surgical treatment for complex penile stricture and it may reduce the rate of contraction of the transplanted BMG.

Memokath Stent Failure in Recurrent Bulbar Urethral Strictures: Results From an Investigative Pilot Stage 2A Study.

OBJECTIVE: To evaluate the efficacy of the Memokath stent in managing recurrent bulbar urethral strictures. MATERIALS AND METHODS: This is an investigative pilot stage 2A study in patients with a recurrent bulbar urethral stricture who underwent a Memokath stent implant from January 2014 to January 2016 in a single high-volume center for urethral reconstruction. The Memokath stent (Pnn Medical A/S, Kvistgaard, Denmark) was manufactured from nitinol, a biocompatible alloy of nickel and titanium, which was endoscopically placed. It had a 24-Fr outside diameter and was preloaded on a disposable delivery device. When correctly positioned, the stent was anchored by a warm water (55°C) instillation, which expanded the proximal end of the stent from 24 to 42 Fr .The stent was provided in lengths of 3-7 cm in 1-cm increments. RESULTS: Sixteen patients were included in the study. The median follow-up was 16 months. In 7 patients (43.7%), the stent was removed within 1 year. The main adverse events were pain, encrustations, stones, and recurrent strictures. Four patients (25%) were considered a success and 12 (75%) were failures. Study limitations include the small sample. CONCLUSION: The Memokath stent was deemed to be not clinically helpful and had significant side effects, and therefore should not be considered a treatment option for men with bulbar urethral strictures.

Microsurgical tunica albuginea transplantation in an animal model.

Several andrological diseases require surgical repair or reconstruction of tunica albuginea, which envelops the corpora cavernosa penis. Despite intense research efforts involving a variety of biological materials, such as skin, muscle aponeurosis, human dura mater, tunica vaginalis, and pericardium, engineered tunica albuginea suitable for graft use is yet to be obtained. The study investigates microsurgical tunica albuginea allotransplantation in an animal model with the purpose of creation of an organ-specific tissue bank to store penile tissue, from cadaveric donors and male-to-female trans-sexual surgery, for allogeneic transplantation. Materials were tunica albuginea tissue explanted from 15 donor rats, cryopreserved at -80°C, gamma-irradiated, and implanted in 15 recipient rats, of which three rats were used as controls. Penile grafts were explanted at different time intervals; after macroscopic evaluation of the organ, the grafts were processed to morphological, histochemical, and immunohistochemical examinations by light microscopy. Detection of pro-inflammatory cytokines was also performed. Examination of the tunica albuginea allografts collected 1, 3, or 6 months after surgery and of control tunica albuginea fragments showed that tunica albuginea implants achieved biointegration with adjacent tissue at all-time points. The integration of cryopreserved rat tunica albuginea allografts, documented by our study, encourages the exploration of tunica albuginea allotransplantation in humans. In conclusion, the effectiveness and reliability of the tunica albuginea conditioning protocol described here suggest the feasibility of setting up a tunica albuginea bank as a further tissue bank.

Sexual outcomes after partial penectomy for penile cancer: results from a multi-institutional study.

Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients' sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study (n = 25) represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up (mean: 14 months; range: 12-25). Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 (IIEF-15). Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function (IIEF-1-5 and -15), orgasmic function (IIEF-9 and -10), sexual desire (IIEF-11 and -12), intercourse satisfaction (IIEF-6-8), and overall satisfaction (IIEF-13 and -14). Then, we also used Quality of Erection Questionnaire (QEQ), Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and Self-Esteem and Relationship (SEAR) to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

A combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts is able to improve sexual quality of life in patient with premature ejaculation.

OBJECTIVE: The management of patient affected by premature ejaculation (PE) is nowadays not highly satisfactory. Here, we aimed to evaluate the tolerability and efficacy of a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts in order to improve sexual quality of life in patients with premature ejaculation. MATERIALS AND METHODS: All patients attending to 5 urological centers from January 2015 to March 2015, due to premature ejaculation were enrolled in this study. At the enrolment visit, all subjects underwent self-administered IIEF-5, Male Sexual Health Questionnaire-Ejaculation Disorder (MSHQEjD), PEDT and IELTS (calculated as mean from that perceived by partner and that perceived by patient) and underwent urological visit and laboratory examinations. All patients received one tablet per day of a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts for 3 months (Group A). After 3 months all patients underwent follow-up visit with the same investigations that have been carried out in the enrolment visit. The results were compared with a cohort of patients enrolled in the same period in another urological center and considered as a control group (Group B). All patients in the control group underwent counseling and sexual behavioral treatment without any pharmacological compound. RESULTS: At the follow-up analysis, significant changes in terms of IELT in the Group A (mean difference: 31.90; p < 0.05) at 3 months and versus Group B at the intergroup analysis (mean difference: 30.30; p < 0.05) were reported. In the group A, significant differences from baseline to last follow- up were observed relative to IIEF-5 (mean difference: 1.04; p < 0.05), PEDT (mean difference: -2.57; p < 0.05) and FSH (mean difference: -16.46; p < 0.05). CONCLUSION: In conclusion, patients affected by PE may significantly benefit from oral therapy with a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts in terms of IELT and PEDT scores improvement.

One-stage Penile Urethroplasty Using Oral Mucosal Graft and Glue.

BACKGROUND: Repair of penile urethral strictures is a challenging problem for which different techniques have been suggested. OBJECTIVE: To describe a new surgical technique for one-stage penile urethroplasty using an oral graft and glue, and to assess its safety and efficacy. DESIGN, SETTING, AND PARTICIPANTS: A retrospective review of medical records for patients who underwent one-stage penile urethroplasty using oral mucosa and glue from February 2013 to October 2014 was performed. SURGICAL PROCEDURE: The penile urethra was opened and the urethral plate was incised to create a wide window within which the oral graft was pasted with glue. The urethra was sutured over the catheter. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Clinical data were collected in a database. Intraoperative and postoperative complications and outcomes were assessed. A descriptive statistical analysis was performed. RESULTS AND LIMITATIONS: Fourteen patients were included in the study. Median operative time was 60min. The median postoperative stay was 3 d. Three intraoperative and one postoperative complication occurred. In all patients, voiding cystourethrography 2 wk after surgery failed to show urethral fistula or sacculation. No patients complained of penile chordee or sexual dysfunction after surgery. Median follow-up was 16 mo. Among the 14 patients, 12 (85.7%) procedures were successful and two (14.3%) were failures. Study limitations include the small sample size and short follow-up. CONCLUSIONS: An in vitro study and a one-stage reconstruction of penile urethral strictures with an oral mucosa graft and glue showed that the procedure is safe and efficient, but further studies including larger series of patients and longer follow-up are required. PATIENT SUMMARY: We report on the repair of penile urethral stricture using one-stage urethroplasty with oral mucosa and glue. This new technique was safe and effective, with limited complications and satisfactory outcomes. We plan to increase the use of this technique in the future.
