    Objective: Penile prosthesis implantation is the solution of choice in patients who have failed or present contraindication to the use of all conservative treatment for erectile dysfunction (ED). Overall, satisfaction rates are high, with more than 80% of patients and partners fully satisfied with cosmetic and functional result of surgery. Chronic postoperative pain, penile shortening, soft or hyposensitive glans, pencil like penis syndrome and difficulty to cycle the device represent the most common causes of patient’s dissatisfaction. Satisfaction rates are better assessed with the use of validated questionnaires such as the International Index of Erectile Function (IIEF) and the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) The aim of our study was to analyze the long-term mechanical reliability of the AMS 700CX/CXM inflatable penile prosthesis and the patient’s satisfaction rate using IIEF and EDITS questionaire as standard reference. Materials and methods: A retrospective case notes review of all patients who have undergone implantation of a three pieces inflatable penile prosthesis AMS 700 CX and CXR between October 1997 and December 2010. Overall, 80 patients have undergone implantation of 3 pieces inflatable penile prosthesis AMS 700 CX InhibiZone. Patients have been administered the IIEF-5 and EDITS questionnaires in combination with a non validated 9 domain questionnaire that assesses penile rigidity, sensation, orgasmic function, frequency of intercourse, impact of surgery on the quality of life, satisfaction rate. Results: Overall 10 years survival estimate according to the Kaplan Meier method of AMS 700 CX touch pump and AMS 700 CX momentary squeeze pump are respectively 77.6% and 82.5%. The median postoperative IIEF5 and EDITS score were respectively 21.46 and 73.11, which show a high level of satisfaction. 59 patients (90.8%) were able to cycle the device and were engaging in penetrative sexual intercourse. Conclusions: Penile prosthesis implantation yields excellent results in terms of cosmetic and functional outcome and therefore has a significant impact on patients’ satisfaction, sex life and overall quality of life. Overall, long term reliability has been significantly improved and complication rates are low in the hands of experienced surgeons

    Abstract Vesico-urethral anastomotic stenosis (VUAS) after radical prostatectomy is a narrowing of the vesicourethral anastomosis after radical prostatectomy. We aim to describe a safe re-anastomotic procedure for recurrent bladder neck contracture following radical prostatectomy (RP). This technique allows an easier access to the stenotic vesico-urethral anastomosis, a better mobilization of the bladder neck and a tension free re-anastomosis. Twelve patients suffering from VUAS after radical prostatectomy were enrolled between May 2014 and September 2018. We describe our approach to the disease. The evaluated outcomes were intra- and post-operative complications, stricture recurrence, and postoperative stress incontinence. Average operative time was 3 h. No major intraoperative complications or bleeding occurred. Patients were discharged after 72 h. At the time of catheter removal, 3 weeks after surgery, 9 out of twelve patients developed stress urinary incontinence, requiring 4 pads/day. Two patients with history of pelvic radiotherapy developed a surgical site abscess that required toilette and external urinary diversion. One recurrence occurred and was treated with internal urethrotomy before sphincter placement. No patient reported significant postoperative pain or fecal incontinence. Our approach allows direct access to the posterior urethra, and we demonstrate the advantages for treatment of VUAS to achieve a tension free anastomosis. All patients need to be informed of subsequent urinary incontinence to be treated with artificial sphincter placement. Patients with a history of pelvic radiotherapy show very poor preoperative conditions of the tissues and must be informed about the possibility of an external urinary diversion

    Sigma-2 Receptors as Potential Novel Biomarkers During the Progression of Benign Prostatic Hypertrophy (BPH) into Prostate Cancer

    Get PDF
    Abstract: BPH could be considered the most common benign tumor for men between 60 and 75 years of age. PSA is an unsatisfactory biomarker to define BPH progression to cancer. Recently, sigma-2 receptors have been recognized in several prostate cancer cell lines such as PC-3, DU-145 and LNCaP. It is reported that, in some cases, BPH could progress to malignancy and this progression can not easily be monitored by biomarkers such as PSA. In this paper we investigated 10 specimens from TURP, finding overexpression of sigma-2 receptors in two of these specimens (specimen 1 and 2) accompanied by 4 ng/mL PSA values. We hypothesize that the presence of sigma-2 receptors is related to a BPH progressing in prostate cancer. A possible correlation between sigma-2 receptors and PSA values could be useful to identify this pathological progression

    Sensitivity and reproducibility of standardized-competitive RT-PCR for transcript quantification and its comparison with real time RT-PCR

    BACKGROUND: Probe based detection assays form the mainstay of transcript quantification. Problems with these assays include varying hybridization efficiencies of the probes used for transcript quantification and the expense involved. We examined the ability of a standardized competitive RT-PCR (StaRT PCR) assay to quantify transcripts of 4 cell cycle associated genes (RB, E2F1, CDKN2A and PCNA) in two cell lines (T24 & LD419) and compared its efficacy with the established Taqman real time quantitative RT-PCR assay. We also assessed the sensitivity, reproducibility and consistency of StaRT PCR. StaRT PCR assay is based on the incorporation of competitive templates (CT) in precisely standardized quantities along with the native template (NT) in a PCR reaction. This enables transcript quantification by comparing the NT and CT band intensities at the end of the PCR amplification. The CT serves as an ideal internal control. The transcript numbers are expressed as copies per million transcripts of a control gene such as ő≤-actin (ACTB). RESULTS: The NT and CT were amplified at remarkably similar rates throughout the StaRT PCR amplification cycles, and the coefficient of variation was least (<3.8%) when the NT/CT ratio was kept as close to 1:1 as possible. The variability between the rates of amplification in different tubes subjected to the same StaRT PCR reaction was very low and within the range of experimental noise. Further, StaRT PCR was sensitive enough to detect variations as low as 10% in endogenous actin transcript quantity (p < 0.01 by the paired student's t-test). StaRT PCR correlated well with Taqman real time RT-PCR assay in terms of transcript quantification efficacy (p < 0.01 for all 4 genes by the Spearman Rank correlation method) and the ability to discriminate between cell types and confluence patterns. CONCLUSION: StaRT PCR is thus a reliable and sensitive technique that can be applied to medium-high throughput quantitative transcript measurement. Further, it correlates well with Taqman real time PCR in terms of quantitative and discriminatory ability. This label-free, inexpensive technique may provide the ability to generate prognostically important molecular signatures unique to individual tumors and may enable identification of novel therapeutic targets

    Central nervous system (brain or leptomeningeal) metastases (BLm) are considered rare in castration-resistant prostate cancer (CRPC) patients. Now that docetaxel has become the reference drug for first-line treatment of CRPC, patients whose disease is not controlled by hormonal manipulations may live much longer than before and have higher risk of developing BLm. We retrospectively reviewed the records of all patients with CRPC attending our centres from 2002 to 2010, and identified all of those who were diagnosed as having BLm and received (or were considered to have been eligible to receive) docetaxel-based treatment. We identified 31 cases of BLm (22 brain metastases and 9 leptomeningeal metastases) with an incidence of 3.3%. BLm-free survival was 43.5 months, and survival after BLm discovery was 4 months. With six patients surviving for more than 1 year after developing BLm, the projected 1-year BL-S rate was 25.8%. The findings of our study may be relevant in clinical practice as they indicate that incidence of BLm in CRPC patients in the docetaxel era seems to be higher than in historical reports, meaning that special attention should be paid to the appearance of neurological symptoms in long-term CRPC survivors because they may be related to BLm

    Laparoscopic and robotic ureteral stenosis repair: a multi-institutional experience with a long-term follow-up

    Get PDF
    The treatment of ureteral strictures represents a challenge due to the variability of aetiology, site and extension of the stricture; it ranges from an end-to-end anastomosis or reimplantation into the bladder with a Boari flap or Psoas Hitch. Traditionally, these procedures have been done using an open access, but minimally invasive approaches have gained acceptance. The aim of this study is to evaluate the safety and feasibility and perioperative results of minimally invasive surgery for the treatment of ureteral stenosis with a long-term follow-up. Data of 62 laparoscopic (n\uc2&nbsp;=\uc2&nbsp;36) and robotic (n\uc2&nbsp;=\uc2&nbsp;26) treatments for ureteral stenosis in 9 Italian centers were reviewed. Patients were followed according to the referring center\ue2\u80\u99s protocol. Laparoscopic and robotic approaches were compared. All the procedures were completed successfully without open conversion. Average estimated blood loss in the two groups was 91.2\uc2&nbsp;\uc2\ub1\uc2&nbsp;71.9\uc2&nbsp;cc for the laparoscopic and 47.2\uc2&nbsp;\uc2\ub1\uc2&nbsp;32.3\uc2&nbsp;cc for the robotic, respectively (p\uc2&nbsp;=\uc2&nbsp;0.004). Mean days of hospitalization were 5.9\uc2&nbsp;\uc2\ub1\uc2&nbsp;2.4 for the laparoscopic group and 7.6\uc2&nbsp;\uc2\ub1\uc2&nbsp;3.4 for the robotic group (p\uc2&nbsp;=\uc2&nbsp;0.006). No differences were found in terms of operative time and post-operative complications. After a median follow-up of 27\uc2&nbsp;months, the robotic group yielded 2 stenosis recurrence, instead the laparoscopic group shows no cases of recurrence (p\uc2&nbsp;=\uc2&nbsp;0.091). Minimally invasive approach for ureteral stenosis is safe and feasible. Both robotic and pure laparoscopic approaches may offer good results in terms of perioperative outcomes, low incidence of complications and recurrence

    Contemporary urologic minilaparoscopy : indications, techniques, and surgical outcomes in a multi-institutional European cohort

    OBJECTIVES: To provide an analytical overview of contemporary indications, techniques, and outcomes of urologic minilaparoscopy (ML) in multiple European centers. METHODS: Data of patients who had undergone a minilaparoscopic urologic procedure at nine European institutions between 2009 and 2012 were retrospectively gathered. Surgical procedures were classified as upper or lower urinary tract and as ablative or extirpative and reconstructive. The main surgical outcome parameters were analyzed and relevant operative data related to the surgical technique were recorded. RESULTS: Overall, 192 patients (mean age 45.25¬Ī17.8 years) were included in the analysis. Most of them were nonobese (mean body mass index [BMI] 24.7¬Ī3.6?kg/m(2)) at low estimated surgical risk (mean American Society of Anesthesiologists [ASA] 1.69¬Ī0.68). Indications for surgery were mostly nononcologic (132 cases, 68.8%). Most of the procedures were done in the upper urinary tract (133 cases, 69.2%) and were mostly with a reconstructive intent (109 cases, 56.7%). Overall operative time was 132.7¬Ī52.3 minutes with an estimated blood loss of 60.9¬Ī47.6?mL while the mean hospital stay was 5¬Ī2.1 days. Most of the postoperative complications were low Clavien grade (1 and 2), with only one (0.5%) grade 3 and one (0.5%) grade 4 complications recorded. CONCLUSIONS: A broad range of common procedures can be safely and effectively performed with ML techniques. By duplicating the principles of standard laparoscopy, but potentially offering less surgical scar and trauma, ML can be regarded as a viable option when looking for a virtually "scarless" surgery

    Purpose The primary aim of this study was to evaluate if exposure to 5-alpha-reductase inhibitors (5-ARIs) modifies the effect of MRI for the diagnosis of clinically significant Prostate Cancer (csPCa) (ISUP Gleason grade &gt;= 2).Methods This study is a multicenter cohort study including patients undergoing prostate biopsy and MRI at 24 institutions between 2013 and 2022. Multivariable analysis predicting csPCa with an interaction term between 5-ARIs and PIRADS score was performed. Sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of MRI were compared in treated and untreated patients.Results 705 patients (9%) were treated with 5-ARIs [median age 69 years, Interquartile range (IQR): 65, 73; median PSA 6.3 ng/ml, IQR 4.0, 9.0; median prostate volume 53 ml, IQR 40, 72] and 6913 were 5-ARIs naive (age 66 years, IQR 60, 71; PSA 6.5 ng/ml, IQR 4.8, 9.0; prostate volume 50 ml, IQR 37, 65). MRI showed PIRADS 1-2, 3, 4, and 5 lesions in 141 (20%), 158 (22%), 258 (37%), and 148 (21%) patients treated with 5-ARIs, and 878 (13%), 1764 (25%), 2948 (43%), and 1323 (19%) of untreated patients (p &lt; 0.0001). No difference was found in csPCa detection rates, but diagnosis of high-grade PCa (ISUP GG &gt;= 3) was higher in treated patients (23% vs 19%, p = 0.013). We did not find any evidence of interaction between PIRADS score and 5-ARIs exposure in predicting csPCa. Sensitivity, specificity, PPV, and NPV of PIRADS &gt;= 3 were 94%, 29%, 46%, and 88% in treated patients and 96%, 18%, 43%, and 88% in untreated patients, respectively.Conclusions Exposure to 5-ARIs does not affect the association of PIRADS score with csPCa. Higher rates of high-grade PCa were detected in treated patients, but most were clearly visible on MRI as PIRADS 4 and 5 lesions.Trial registration The present study was registered at ClinicalTrials.gov number: NCT05078359

    Changes in renal function after nephroureterectomy for upper urinary tract carcinoma: analysis of a large multicenter cohort (Radical Nephroureterectomy Outcomes (RaNeO) Research Consortium)

    Purpose To investigate prevalence and predictors of renal function variation in a multicenter cohort treated with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Methods Patients from 17 tertiary centers were included. Renal function variation was evaluated at postoperative day (POD)-1, 6 and 12 months. Timepoints differences were Delta 1 = POD-1 eGFR - baseline eGFR; Delta 2 = 6 months eGFR - POD-1 eGFR; Delta 3 = 12 months eGFR - 6 months eGFR. We defined POD-1 acute kidney injury (AKI) as an increase in serum creatinine by >= 0.3 mg/dl or a 1.5 1.9-fold from baseline. Additionally, a cutoff of 60 ml/min in eGFR was considered to define renal function decline at 6 and 12 months. Logistic regression (LR) and linear mixed (LM) models were used to evaluate the association between clinical factors and eGFR decline and their interaction with follow-up. Results A total of 576 were included, of these 409(71.0%) and 403(70.0%) had an eGFR < 60 ml/min at 6 and 12 months, respectively, and 239(41.5%) developed POD-1 AKI. In multivariable LR analysis, age (Odds Ratio, OR 1.05, p < 0.001), male gender (OR 0.44, p = 0.003), POD-1 AKI (OR 2.88, p < 0.001) and preoperative eGFR < 60 ml/min (OR 7.58, p < 0.001) were predictors of renal function decline at 6 months. Age (OR 1.06, p < 0.001), coronary artery disease (OR 2.68, p = 0.007), POD-1 AKI (OR 1.83, p = 0.02), and preoperative eGFR < 60 ml/min (OR 7.80, p < 0.001) were predictors of renal function decline at 12 months. In LM models, age (p = 0.019), hydronephrosis (p < 0.001), POD-1 AKI (p < 0.001) and pT-stage (p = 0.001) influenced renal function variation (ss 9.2 +/- 0.7, p < 0.001) during follow-up. Conclusion Age, preoperative eGFR and POD-1 AKI are independent predictors of 6 and 12 months renal function decline after RNU for UTUC
