Mechanical and Ablative Minimally Invasive Techniques for Male LUTS due to Benign Prostatic Obstruction: A Systematic Review according to BPH-6 Evaluation.

The treatment of male lower urinary tract symptoms (LUTS) due to benign prostatic obstruction represents one of the major interesting aspects in urological clinical practice. Although transurethral resection of the prostate is still considered the surgical gold standard for treatment of benign prostatic hyperplasia with prostate volume <80 mL, various minimally invasive surgical treatments (MITs) have been developed to overcome the limitations of the "conventional" surgery. To date, there are no validated tools to evaluate the surgical outcomes of MITs; however, in the past, BPH-6 has been used for this purpose. In this systematic review, we evaluated the efficacy and safety of MITs according to BPH-6 score system. We focused our attention on MITs based on mechanical devices (prostatic urethral lift and the temporary implantable nitinol device) and techniques for prostate ablation (image guided robotic waterjet ablation and convective water vapor energy ablation). Evidence shows that MITs are capable of leading to an improvement in LUTS without having an overwhelming impact on complications and are a valid alternative to other treatments in patients who wish to preserve their sexual function or in case of inapplicability of conventional surgery. However, comparative studies between these techniques are still missing.

The Role of Postoperative Imaging after Ventral Onlay Buccal Mucosal Graft Bulbar Urethroplasty.

PURPOSE: Our primary objective was to determine the incidence of extravasation on imaging at the time of catheter removal after ventral onlay buccal mucosal graft urethroplasty. MATERIALS AND METHODS: This is a single center retrospective cohort study of patients who underwent ventral onlay buccal mucosal graft bulbar urethroplasty from 2007 to 2017. Patients with imaging at the time of catheter removal were included. Urethroplasty success was defined as the ability to pass a 17Fr cystoscope at the time of followup cystoscopy. RESULTS: A total of 229 patients met the inclusion criteria, including 110 with a ventral onlay buccal mucosal graft and 119 with an augmented anastomotic urethroplasty with a mean stricture length of 4.4 cm. Imaging consisted of a voiding cystourethrogram in 210 and retrograde urethrogram in 19 patients at a median of 21.7 days after surgery. The incidence of extravasation was 3.1% (7/229). Of patients who had a documented followup cystoscopy (60%, 137/229), those with extravasation on imaging had a worse urethroplasty success rate (60%, 3/5) compared to those who did not (94%, 117/130) (p=0.047). On multivariate analysis those who had 5 or more endoscopic interventions were 9.6 times more likely to demonstrate extravasation (OR 9.6, p=0.0080). CONCLUSIONS: The incidence of radiological extravasation after ventral onlay using a single buccal mucosal graft, with or without augmented anastomotic urethroplasty, is 3.1%. Given this low rate it is reasonable to omit routine imaging at the time of Foley removal in this population. It appears that extravasation may be associated with a worse cystoscopic patency rate but does not lead to more complications.

Retropubic vs transobturator Argus adjustable male sling: Results from a multicenter study.

AIMS: To comparatively analyse outcomes after ARGUS classic and ArgusT adjustable male sling implantation in a real-world setting. METHODS: Inclusion criteria encompassed: non-neurogenic, moderate-to-severe stress urinary incontinence (≥2 pads), implantation of an ARGUS classic or ArgusT male sling between 2010 and 2012 in a high-volume center (>150 previous implantations). Functional outcomes were assessed using daily pad usage, 24-hour pad testing, and International Consultation on Incontinence (ICIQ-SF) questionnaires. Continence was defined as zero pads per 24 hours. Complications were graded using Clavien-Dindo scale. For multivariate analysis, binary logistic regression models were used (P < .05). RESULTS: A total of 106 patients (n = 74 [ARGUS classic], n = 32 [ArgusT]) from four centers were eligible. Median follow-up was 44.0 months (24-64). Patient cohorts were well-balanced. We observed a statistical trend in favor of ARGUS classic regarding postoperative urine loss based on standardized 24-hour pad test (71 ± 162 g [ARGUS classic] vs 160 ± 180 g [ArgusT]); P = .066]. Dry rates were 33.3% (ARGUS classic) and 11.8% (ArgusT, P = .114). In multivariable analysis, ArgusT male sling could not be confirmed as an independent predictor of decreased success (OR, 0.587; 95% CI; 0.166-2.076, P = .408). There were no Clavien IV and V complications. Inguinal pain was significantly higher after ArgusT implantation (P = .033). Explantation rates were higher for ArgusT compared to ARGUS classic (14.0 vs 23.3%; P = .371). Longer device survival for the ARGUS classic male sling was observed in Kaplan-Meier analysis (P = .198). CONCLUSIONS: In the largest comparative analysis of ARGUS classic and ArgusT male sling with the longest follow-up to date, we observed low continence rates with superior functional outcomes and decreased explantation rates after ARGUS classic implantation.

The Rezum system - a minimally invasive water vapor thermal therapy for obstructive benign prostatic hyperplasia.

Benign prostatic hyperplasia (BPH) and accompanying lower urinary tract symptoms (LUTS) sits in the top ten prominent and costly disease conditions in men over 50 years of age. In the United States it is the most common diagnosis made by urologists for men 45 to 74 years of age. Twenty percent of the population will reach 65 years of age or older by 2030, and those over 85 years will represent the fastest growing segment of our population. The prevalence of symptomatic BPH increases proportionally with the aging population. It is estimated that BPH now affects 6% of the male population worldwide. Moreover, in Canada, the estimated BPH prevalence is more than 1 million men aged 50 years and older. Among the various surgical treatments, Rezum water vapor thermal therapy has been developed as a unique, rapid and reproducible minimally invasive surgical treatment exhibiting safe and early effective relief of LUTS/BPH. The targeted prostate tissue ablation is amenable to all zones of the prostate including intravesical median lobes. We present our experiences with this technique, which can be quickly performed under local anesthesia in an office setting.

Use of a Stent in Distal Hypospadias Repaired by Tubularized Incised Plate Urethroplasty: A Comparative Study.

PURPOSE: We present our experience of stented and unstented distal hypospadias repaired by tubularized incised plate urethroplasty (TIPU). PATIENTS AND METHODS: Data of 84 patients who were operated by TIPU method in 2 hospitals were retrospectively analyzed, and they were invited to be included in the study. Sixty-six patients agreed to participate in the study and were divided into 2 groups. Group 1 consisted of 38 boys operated in Sütçü Imam University Hospital on using a stent between 2015 and 2017. Group 2 consisted of 28 boys operated in Private Hospital of Megapark on without a stent between 2016 and 2017. The hypospadias objective scoring evaluation (HOSE) scale was used to compare the groups. RESULTS: The median age was 2.81 years in group 1 and 1.95 years in group 2 (p = 0.243). The mean follow-up duration was 25.74 ± 4.62 and 24.5 ± 4.19 months in groups 1 and 2 respectively (p = 0.268). The HOSE scores were similar in both groups with comparable results (p = 0.622). CONCLUSIONS: No difference was observed between the groups in this study, regarding functional and cosmetic outcomes according to the HOSE score. However, the results should be supported by prospective studies with a sufficient number of patients.

Repair of injured urethras with silk fibroin scaffolds in a rabbit model of onlay urethroplasty.

BACKGROUND: Preclinical validation of scaffold-based technologies in animal models of urethral disease is desired to assess wound healing efficacy in scenarios that mimic the target patient population. This study investigates the feasibility of bilayer silk fibroin (BLSF) scaffolds for the repair of previously damaged urethras in a rabbit model of onlay urethroplasty. MATERIALS AND METHODS: A focal, partial thickness urethral injury was created in adult male rabbits (n = 12) via electrocoagulation and then onlay urethroplasty with 50 mm2 BLSF grafts was carried out 2 wk after injury. Animals were randomly divided into three experimental groups and harvested at 2 wk after electrocoagulation (n = 3), and 1 (n = 3) or 3 (n = 6) months after scaffold implantation. Outcome analyses were performed preoperatively and at 2 wk after injury in all groups as well as at 1 or 3 mo after scaffold grafting and included urethroscopy, retrograde urethrography (RUG), and histological and immunohistochemical analyses. RESULTS: At 2 wk after electrocoagulation, urethroscopic and RUG evaluations confirmed urethral stricture formation in 92% (n = 11/12) of rabbits. Gross tissue assessments at 1 (n = 3) and 3 (n = 6) mo after onlay urethroplasty revealed host tissue ingrowth covering the entire implant site. At 3 mo post-op, RUG analyses of repaired urethral segments demonstrated a 39% reduction in urethral stenosis detected following electrocoagulation injury. Histological and immunohistochemical analyses revealed the formation of innervated, vascularized neotissues with α-smooth muscle actin+ and SM22α+ smooth muscle bundles and pan-cytokeratin + epithelium at graft sites. CONCLUSIONS: These results demonstrate the feasibility of BLSF matrices to support the repair of previously damaged urethral tissues.

The TiLOOP® Male Sling: Did We Forejudge.

INTRODUCTION: To evaluate the safety and efficacy of the TiLOOP® male sling (pfm medical, Cologne, Germany) used in the treatment for male stress urinary incontinence (SUI). MATERIAL AND METHODS: We retrospectively evaluated a total of 34 patients with a TiLOOP® male sling. Perioperative complication rates were assessed and validated questionnaires were prospectively evaluated to assess quality of life and satisfaction rate. Outcome and complication rates were analysed by using descriptive statistics. Correlation of continence outcome and risk factors was performed with the chi-square test. A p value below 0.05 was considered statistically significant. RESULTS: The majority of patients (70.6%) were diagnosed with mild or moderate male SUI. During surgery, one instance (2.9%) of intraoperative urethral injury was observed. There were no immediate postoperative complications. The mean follow-up time was 44.6 months. An improvement of male SUI was reported by 61.9% of the patients and 38.1% reported no change according the Patient Global Impression of Improvement. The mean perineal pain score was 0.5 according to the international index of pain. CONCLUSIONS: The TiLOOP® is a safe treatment option for male SUI in our cohort with a low complication rate. However, the functional outcome of the TiLOOP® was inferior when compared to the outcome of the AdVance® male sling.

Can time to failure predict the faulty component in artificial urinary sphincter device malfunctions?

OBJECTIVE: Artificial urinary sphincter malfunctions can occur in any of the individual components. Preoperative identification of the malfunctioning component can be valuable for patient counseling and surgical planning. The optimal strategy for repair of failed artificial urinary sphincter components is debated given the relative rarity of the situation. The aim of the present study was to evaluate the relationship of time to failure with failed artificial urinary sphincter component and to compare our outcomes of specific component versus complete device replacement. METHODS: From 1983 to 2011, 1805 artificial urinary sphincter procedures were carried out at Mayo Clinic (Rochester, Minnesota, USA), of which 1072 patients underwent primary artificial urinary sphincter placement. Clinical variables, including time to failure, were evaluated for association with component failure. Bootstrap analysis was used to estimate the differences in time to reach a fixed percentage of component failure. RESULTS: A total of 115 patients experienced device failure at a median follow up of 4.2 years. Urethral cuff, abdominal reservoir, scrotal pump and tubing malfunction occurred in 53 (4.9%), 26 (2.4%), 11 (1%) and 25 (2.3%) patients, respectively. Increasing age at the time of primary surgery was protective of cuff malfunction (hazard ratio 0.97, P = 0.04). Time to 3% urethral cuff failure outpaced other component failures (P < 0.05). Secondary failure-free rates after whole device versus specific component revisions were comparable (P = 0.38). CONCLUSIONS: Clinical predictors for artificial urinary sphincter failure continue to be difficult to establish. Although single component versus entire device replacement have similar outcomes, if pursuing single component revision, we recommend cuff-first interrogation in devices in place for >3 years, as this represents the most likely component to fail.

[Is transition from pure laparoscopic to robotic-assisted radical prostatectomy associated with increase of surgical procedures for urinary incontinence and erectile dysfunction?] / L'introduction de la chirurgie robot-assistée pour la prostatectomie totale s'accompagne-t-elle d'une modification du nombre d'interventions secondaires pour troubles fonctionnels génito-urinaires ?

OBJECTIVE: To study the impact of changing the technique of radical prostatectomy [pure laparoscopic radical (PR-Lap) to robot-assisted radical prostatectomy (RP-Rob)] on the rate of secondary procedures for urinary incontinence (UI) and erectile dysfunction (ED). MATERIAL: Retrospective study evaluating the number and type of surgical procedures for post-RP UI and DE between 2008 and 2015, according to the technique of (RP-Lap or RP-Rob). RESULTS: Between 2008 et 2015, 2046 RP were performed in our department including 372 RP-Lap and 1674 RP-Rob. Among these patients, 84 (4%) had a surgical procedure for post-RP UI (18 AMS800, 9 balloons Pro-Act, and 57 male slings) and 15 (0.7%) had implantation of penile prosthesis for post-RP ED; 16 (0.7%) patients had both procedures. The mean delay between RP and UI surgery decrease from 3.2 years in 2008 to 1 year in 2015 and remain stable for penile prosthesis implantation (mean delay: 3.4 years). The overall rates of secondary procedures for UI and DE remained stable and below 5% and 1.7%, respectively, even during the transition period. For each year of PR studied, the rates of secondary procedure were higher in the RP-Lap group. CONCLUSION: Changing the technique of RP from RP-Lap to PR-Rob has a favorable impact on the rate of secondary procedures for UI and ED from the outset.

Is stent type used in snodgrass method a factor in fistula formation?

CONTEXT: Snodgrass method (tubularized incised plate urethroplasty [TIPU]) is a widely used technique for hypospadias repair. AIM: It was aimed to compare the outcome of hypospadias repair with stenting using feeding tube compare with those with Foley catheter. SUBJECTS AND METHODS: The demographic characteristics of the 123 patients who underwent hypospadias repair with Snodgrass method, the success of the applied method, and the factors affecting fistula complication were evaluated retrospectively. Patients were divided into two groups: those operated before January 2010 (Group A) and those who were operated after (Group B). In Group A patients, urethroplasty was performed using silicone Foley catheters, in which balloon of these catheters was filled by saline at appropriate size. In Group B, urethroplasty was performed using feeding catheter. RESULTS: Group A and Group B consisted of 32 and 91 patients, respectively. Fistula developed in 10 (31.3%) and 4 (4.39%) patients in Group A and Group B, respectively. There was a statistically significant difference between the two groups in terms of the development of fistula complication (P = 0.0002). CONCLUSION: The use of a feeding catheter in TIPU could be a more advantageous than using a Foley catheter.

Analysis of preoperative antibiotic prophylaxis in stented, distal hypospadias repair.

INTRODUCTION: Surgical site infection [SSI] is a risk for any surgical procedure, including hypospadias repair. Prophylactic antibiotic therapy for patients having surgery is often effective in preventing SSIs, but with increasing rates of antibiotic resistance, this practice has been questioned. The objectives of this study are 1) to assess the incidence of SSIs in patients following stented, distal hypospadias repair and 2) to observe for any potential difference in the incidence of SSIs for patients with and without preoperative antibiotic utilization in this setting. MATERIALS AND METHODS: We retrospectively reviewed consecutive patients treated with stented, distal hypospadias repair from 2011 to 2014 by three surgeons and compared two groups: patients who received preoperative antibiotics and patients who did not. Patients with a history of previous hypospadias repair were excluded from the study. RESULTS: Two hundred twenty-four subjects were identified. Group 1 (135) received preoperative antibiotic and Group 2 (89) did not receive preoperative antibiotics. There was no statistically significant difference in SSI prevalence with 0 patients in Group 1 and 1 patient in Group 2 having a SSI. CONCLUSION: Although prophylactic antibiotics prior to hypospadias repair are most often used by pediatric urologists, this study demonstrates further evidence that antibiotics prior to this procedure do not appear to lower the rate of SSI. This study is limited by its retrospective nature and disparate mean follow up in the two cohorts. Surgical site infection does not appear to be decreased by prophylactic antibiotic therapy before distal hypospadias repair.

Risk Factors for Failure of Male Slings and Artificial Urinary Sphincters: Results from a Large Middle European Cohort Study.

INTRODUCTION: We analysed the impact of predefined risk factors: age, diabetes, history of pelvic irradiation, prior surgery for stress urinary incontinence (SUI), prior urethral stricture, additional procedure during SUI surgery, duration of incontinence, ASA-classification and cause for incontinence on failure and complications in male SUI surgery. MATERIALS AND METHODS: We retrospectively identified 506 patients with an artificial urinary sphincter (AUS) and 513 patients with a male sling (MS) in a multicenter cohort study. Complication rates were correlated to the risk factors in univariate analysis. Subsequently, a multivariate logistic regression adjusted to the risk factors was performed. A p value <0.05 was considered statistically significant. RESULTS: A history of pelvic irradiation was an independent risk factor for explantation in AUS (p < 0.001) and MS (p = 0.018). Moreover, prior urethral stricture (p = 0.036) and higher ASA-classification (p = 0.039) were positively correlated with explantation in univariate analysis for AUS. Urethral erosion was correlated with prior urethral stricture (p < 0.001) and a history of pelvic irradiation (p < 0.001) in AUS. Furthermore, infection was correlated with additional procedures during SUI surgery in univariate analysis (p = 0.037) in MS. CONCLUSIONS: We first identified the correlation of higher ASA-classification and explantation in AUS. Nevertheless, only a few novel risk factors had a significant influence on the failure of MS or AUS.

Intraoperative breakage of Sachse's knife blade: A rare complication of optical internal urethrotomy (one case managing experience).

Optical internal urethrotomy (OIU) is the most common procedure performed for short segment bulbar urethral stricture worldwide. This procedure most commonly performed using Sachse's cold knife. Various perioperative complications of internal urethrotomy have been described in literature including bleeding, urinary tract infection, extravasation of fluid, incontinence, impotence, and recurrence of stricture. Here we report a unique complication of breakage of Sachse knife blade intraoperatively and its endoscopic management.

Urolift: a New Face of Minimally Invasive Surgical Technique for Benign Prostatic Hyperplasia?

The management of clinical benign prostatic hyperplasia (BPH) remains a common problem in daily urologic practice. Recently, a new minimally invasive procedure for BPH, the Urolift System, has been introduced. This article reviews the current literature discussing the technique, efficacy, adverse events, limitations, and possible concerns. The existing data which includes a 3-month, sham-controlled multicenter trial with a subsequent 3-year follow-up indicates significant improvements in the outcome measures in particular urinary symptoms. The adverse event profile and reoperation rates are acceptable. A particular benefit includes the lack of negative effects on erectile or ejaculatory function. The procedure can be performed with minimal anesthesia, but is limited to lateral lobe enlargement as it is unsuitable for median lobe or central zone obstruction. Another potential drawback is the placement of permanent implants into the prostatic urethra. The adoption of this procedure will ultimately be determined by multiple factors including ease of use, patient satisfaction, durability, and reimbursement.

Prostatic Urethral Lift: A New Minimally Invasive Treatment for Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.

INTRODUCTION: Prostatic urethral lift (PUL) is a minimally invasive procedure for the treatment of lower urinary tract symptoms (LUTSs) secondary to benign prostatic hyperplasia (BPH). The PUL procedure involves the placement of implants that retract the obstructing prostate lobes. This procedure achieves quantifiable improvements in functional outcomes and quality of life (QoL), while preserving erectile and ejaculatory functions. METHODS: Seventeen patients diagnosed with BPH who had undergone the UroLift® procedure between March 2011 and June 2015 were retrospectively evaluated. The parameters evaluated in the pre-operative, intra-operative and 1-year post-operative period were demographic data, and pre-operative, intra-operative and 1-year post-operative results were obtained from the International Prostate Symptom Score (IPSS), Uroflowmetry QoL index, International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire (MSHQ) for ejaculatory function (MSHQ-EjD). RESULTS: The average improvements from baseline to 12 months after intervention were significant for the total IPSS 9.6. There was a 4.2-point increase in Qmax, a 0.9-point improvement in QoL and a 32% decrease in PVR. No statistically significant difference was found in the IIEF and MSHQ-EjD scores when the pre-operative and post-operative 3rd and 12th month scores were evaluated (p > 0.05). CONCLUSIONS: PUL offers rapid improvement in voiding and storage symptoms, QoL and flow rate that is durable to 12 months after intervention. PUL is a minimally invasive procedure that has the moderate effect in treating troublesome LUTS secondary to benign prostatic obstruction and preserving total sexual function.

Argus-T Adjustable Male Sling: The Influence of Surgical Technique on Complications and Short-Term Efficacy.

OBJECTIVES: The study aims to investigate and evaluate the influence of 2 different methods of implantation of the Argus transobturator (Argus-T) adjustable male sling on complication rate and short-term efficacy. METHODS: A prospective mono-center evaluation was conducted on consecutive patients treated for persistent post-radical prostatectomy incontinence. Thirty-six patients were implanted with the Argus-T adjustable male sling--18 by inguinal-perineal incision (IPI) and 18 by single-perineal incision (SPI). Measurements included 24-hour frequency volume micturition list, 24-hour pad test, 24-hour pad count, Visual Analogue Scale for continence and satisfaction, flowmetry and residual voided urine. RESULTS: Cure rate for IPI and SPI at 1, 6 and 12 months was 67, 75, 62% and 59, 63, 63%, respectively (no statistically significant difference). Although more clinically significant complications were seen in the IPI group, a statistical significant difference was observed only for wound infection between the IPI and the SPI groups (33 vs. 0%, p = 0.019). CONCLUSIONS: The Argus-T male sling SPI suspension operation is a minimally invasive and safe procedure for the management of male postoperative stress incontinence which is highly appreciated by the patients.

Primary Endoscopic Realignment of Urethral Disruption Injuries--A Double-Edged Sword?

PURPOSE: Controversy remains regarding initial management of traumatic urethral disruption injuries. We evaluated the outcomes of primary endoscopic realignment vs suprapubic tube placement in this patient population. MATERIALS AND METHODS: We reviewed our urological trauma database for patients with blunt trauma related posterior urethral injuries from 2000 to 2014. Patients underwent primary endoscopic realignment or suprapubic tube placement alone. The primary outcome was the success of primary realignment, defined as no further need for urological intervention. Secondary outcomes were the need for endoscopic interventions and/or urethroplasty, time to urethroplasty, urethroplasty success and long-term functional outcomes. RESULTS: A total of 27 patients underwent primary realignment and 14 underwent suprapubic tube placement. Mean followup was 40 months (median 24, range 1 to 152). Realignment was successful in 10 patients (37%) at a mean followup of 67.3 weeks (median 27.3, range 4 to 284). In the 17 cases (63%) that failed mean time to failure was 9.7 weeks (median 8.5, range 1 to 26). Seven patients (26%) treated with realignment and 11 (79%) with a suprapubic tube proceeded to urethroplasty. Mean ± SD time to urethroplasty was significantly shorter in the suprapubic tube group (14.6 ± 7.6 vs 5.8 ± 1.6 months, p = 0.003). There was no difference in operative time, complications, success or functional outcomes. CONCLUSIONS: Management of traumatic urethral disruption injuries by primary endoscopic realignment serves as definitive therapy in more than a third of treated patients. It prevents the need for formal urethroplasty in more than half of failed cases.

The advance transobturator male sling for post-prostatectomy incontinence: subjective and objective outcomes with 3 years follow up.

AIMS: To determine patient-perceived and clinical outcomes of the AdVance sling at 3 years follow-up in men with post-prostatectomy incontinence (PPI). METHODS: Data was prospectively collected of men with PPI treated with the AdVance male sling between February 2008 and March 2010. Twenty-four-hour pad counts and weights and patient completed validated questionnaires were obtained pre-operatively and at 3 years. The primary outcome was improvement in pad count with secondary outcomes of questionnaire scores and patient perception of success. RESULTS: At a median follow-up of 39 months (IQR: 36-44), we identified 30 men meeting inclusion criteria who had the AdVance male sling placed for mild to severe PPI. Eighteen (60%) patients were cured (no pad usage or one pad for security) and an additional 4 (13%) showed improvement (≥50% reduction in pad usage). Eight (27%) patients failed: six patients underwent seven salvage procedures including urethral bulking with collagen (n = 1), Virtue perineal sling (n = 1), and artificial urinary sphincter (n = 5). There were 16 post-operative complications: 13 Clavien I, 2 Clavien II, and 1 Clavien IIIb. CONCLUSIONS: AdVance male sling is an effective treatment option for PPI evidenced by objective improvements in 24-hr pad count and pad weight and patient perceived success via validated questionnaires.

[Application of scrotoscope in the diagnosis and treatment of testicular and epididymal diseases].

OBJECTIVE: To evaluate the safety and efficacy of scrotoscope in diagnosis and treatment of testicular and epididymal diseases. METHODS: From September 2010 to March 2012, a total of 75 patients, aged 15-64 years (mean age is 42.4 years) were included in this study. Based on ultrasonagraphy before surgery, 12 cases were diagnosed as testicular torsion and 63 cases were diagnosed as epididymal mass. All the patients underwent scrotoscope examination or scrotoscope epididymectomy. A small scrotal incision of 1.0 cm was performed. Bluntly dissection was then performed through the scrotal layer until the tunica sac was disclosed. We used cystoscope or resectoscope as scrotoscope. Keeping the drip fusion of isotonic solution inflowing, the scrotum was maintained appropriate distended. The tunica sac wall including parietal and visceral tunica was checked. The testis, epididymis was then examined from the anterior, posterior and both lateral aspects to find out any potential pathology. The operation time of scrotoscope, postoperative complications, surgery record, ultrasound and pathology results were collected from medical record. Visual analog pain scale (range from 0 points to 10 points, 0 represent no pain, 10 represent the most severe pain) was used to assess scrotal pain. The postoperative complications, recurrence and pain relief were evaluated, the accuracy rates of the diagnosis was compared between scrotoscope and ultrasound based on pathology results. RESULTS: All the patients were successfully performed scrotoscope except one because of inflammatory adhesion. The average time of the operation was 34.3±5.8 minutes, and no serious complications, such as severe edema, hematoma, testicular hydrocele and wound infection occurred. The accuracy rate of scrotoscope and ultrasound for the diagnosis of testicular torsion was 100% vs. 66.7%, and the accuracy rate of scrotoscope and ultrasound for the diagnosis of epididymal mass was 76.2% vs. 58.7%. In the study, 63 patients received scrotoscope epididymectomy, the visual analogue pain score before surgery was 7.1±0.8, 6 months after operation, and the pain score was 2.4±0.6. CONCLUSION: Scrotoscope is safe. There are no serious complications such as severe edema, hematoma, testicular hydrocele and wound infection occurred. Scrotoscope is superior to ultrasound for diagnosis of testicular torsion and epididymal mass. Scrotoscope epididymectomy is effective for pain relief, especially for patients with epididymal cyst.

[Are the UroLift(®) implants an alternative for the treatment of benign prostatic hyperplasia? Short-term results and predictive factors of failure]. / La pose d'implants intra-prostatiques UroLift(®) est-elle une alternative chez les patients ayant une hyperplasie bénigne de la prostate ? Résultats initiaux et facteurs prédictifs d'échec.

OBJECTIVE: To report the results of UroLift(®) implants after a 2-year experience in the technique. PATIENTS AND METHODS: The procedure was proposed between February 2012 and April 2014 in patients with symptomatic benign prostatic hyperplasia, as an alternative to standard endoscopic ablation techniques. Evaluation of BPH related symptoms relied on the IPSS and IPSS-QoL self-questionnaires, as well as on maximum uroflow (Qmax). Evaluation of erectile and ejaculatory functions relied on the IIEF5 and MSHQ-EjD self-questionnaires, respectively. RESULTS: A total of 23 patients were treated during this period. Median age was 66 years [53-78]. Median prostate volume was 38mL [20-80]. Preoperative IPSS and IPSS-QoL were 20 [9-29] and 5 [3-6], respectively. No severe adverse event was observed postoperatively. Median follow-up was 14 [5-31] months. At the end of follow-up, 19 (83%) patients reported sustained symptomatic improvement without any additional treatment. Median IPSS and IPSS-QoL were improved significantly (11 [1-27] and 2 [0-6], P<0.0001), with however no significant improvement in Qmax. Four patients needed additional treatment during the first postoperative year. Among them, 3 had a prostate volume>60mL. No patient reported retrograde ejaculation or worsened erectile function. CONCLUSIONS: UroLift(®) implants allowed symptomatic improvement in more than 80% of the patients after 1-year follow-up. A high prostate volume may potentially be predictive of symptomatic failure. LEVEL OF PROOF: 5.
