Managing female urethral diverticulum with a standardized technique using a pacifier-trick artifice to facilitate dissection.

INTRODUCTION AND HYPOTHESIS: Managing urethral diverticula is challenging because of recurrence rate and postoperative complications. Herein, we report a standardized, single-institution experience of surgical treatment of urethral diverticula in women. METHODS: The medical record of 37 female patients treated for urethral diverticula between 2005 and 2017 in a single institution were reviewed. All patients were operated in a standardized genupectoral position using a technical artifice called the pacifier trick to inflate diverticula throughout the procedure and facilitate its dissection. Symptoms at diagnosis, imaging findings, surgical parameters, postoperative complications, and recurrence rates were collected and are presented. RESULTS: Median age was 39 ± 11 (range 21-67) years. At diagnosis, recurrent urinary tract infections (UTI) (67%), vaginal mass (46%), pelvic pain (43%), dyspareunia (27%), and urinary incontinence (UI) (24%) were the most commonly reported symptoms. Median operative time was 98 ± 31 (range 40-150) min. After a mean follow-up of 1 year, recurrence occurred in one (3%) patient. Immediate de novo postoperative UI decreased from 27% immediately after surgery to 3% after pelvic physical therapy. Pathological analyses found no malignant histology. CONCLUSIONS: Surgical management of urethral diverticula in women is technically demanding. With our standardized pacifier-trick technique, satisfying anatomical and functional results were achieved.

Urinary function and quality of life after radiotherapy for prostate cancer in patients with prior history of surgical treatment for benign prostatic hyperplasia.

BACKGROUND: To evaluate long-term IPSS score and urinary quality of life after radiotherapy for prostate cancer, in patients with prior history of surgical treatment for benign prostatic hyperplasia (BPH). METHODS: In this retrospective study, we reviewed medical records of patients treated in our department, between 2007 and 2013 with surgery for BPH followed by radiotherapy for localized prostate cancer. Patients were contacted to fill in IPSS questionnaire and they were also asked for urinary quality of life. Predictive factors known to be associated with bad urinary function were also analysed. RESULTS: Fifty-nine patients were included in our study. Median age was 70 years. Median follow-up was 4.6 years. Median radiotherapy dose was 78 Gy (5 × 2 Gy/week). Thirty patients (48.5%) received hormone therapy in combination with RT. Main surgery indications were urinary symptoms (65%) and urinary retention (20%). Five-year biochemical-disease free survival was 75% and 5-year clinical relapse free survival was 84%. At the time of the study, the IPSS after radiotherapy was as follows: 0-7: 77.6%; 8-19:20.7%; 20-35: 1.7%. Urinary quality of life was satisfactory for 74.2% of patients. After multivariate analysis, a high dose of RT and a medical history of hypertension were associated with a poorer quality of urinary life (p = 0.04). CONCLUSION: External radiotherapy remains an appropriate treatment option without a major risk for deterioration in urinary function in patient with antecedent surgery for BPH. High dose of RT and a medical history of hypertension were associated with a poorer quality of urinary life.

Promoter hypermethylation of HS3ST2, SEPTIN9 and SLIT2 combined with FGFR3 mutations as a sensitive/specific urinary assay for diagnosis and surveillance in patients with low or high-risk non-muscle-invasive bladder cancer.

BACKGROUND: Non-muscle-invasive bladder cancer (NMIBC) is a high incidence form of bladder cancer (BCa), where genetic and epigenetic alterations occur frequently. We assessed the performance of associating a FGFR3 mutation assay and a DNA methylation analysis to improve bladder cancer detection and to predict disease recurrence of NMIBC patients. METHODS: We used allele specific PCR to determine the FGFR3 mutation status for R248C, S249C, G372C, and Y375C. We preselected 18 candidate genes reported in the literature as being hypermethylated in cancer and measured their methylation levels by quantitative multiplex-methylation specific PCR. We selected HS3ST2, SLIT2 and SEPTIN9 as the most discriminative between control and NMIBC patients and we assayed these markers on urine DNA from a diagnostic study consisting of 167 NMIBC and 105 controls and a follow-up study consisting of 158 NMIBC at diagnosis time's and 425 at follow-up time. ROC analysis was performed to evaluate the diagnostic accuracy of each assay alone and in combination. RESULTS: For Diagnosis: Using a logistic regression analysis with a model consisting of the 3 markers' methylation values, FGFR3 status, age and known smoker status at the diagnosis time we obtained sensitivity/specificity of 97.6 %/84.8 % and an optimism-corrected AUC of 0.96. With an estimated BCa prevalence of 12.1 % in a hematuria cohort, this corresponds to a negative predictive value (NPV) of 99.6 %. For Follow-up: Using a logistic regression with FGFR3 mutation and the CMI at two time points (beginning of the follow-up and current time point), we got sensitivity/specificity/NPV of 90.3 %/65.1 %/97.0 % and a corrected AUC of 0.84. We also tested a thresholding algorithm with FGFR3 mutation and the two time points as described above, obtaining sensitivity/specificity/NPV values of, respectively, 94.5 %/75.9 %/98.5 % and an AUC of 0.82. CONCLUSIONS: We showed that combined analysis of FGFR3 mutation and DNA methylation markers on urine can be a useful strategy in diagnosis, surveillance and for risk stratification of patients with NMIBC. These results provide the basis for a highly accurate noninvasive test for population screening and allowing to decrease the frequency of cystoscopy, an important feature for both patient quality of life improvement and care cost reduction.

The Diagnostic and Prognostic Performance of Urinary FGFR3 Mutation Analysis in Bladder Cancer Surveillance: A Prospective Multicenter Study.

OBJECTIVE: To assess the diagnostic and prognostic performance of a noninvasive FGFR3 mutation analysis. After transurethral resection (TUR) of noninvasive bladder transitional cell carcinoma (B-TCC), recurrence occurs in 70% of patients, thus justifying cystoscopic surveillance. MATERIALS AND METHODS: A prospective multicenter study was carried out with a 2-year follow-up of patients with superficial B-TCC. Urine samples were collected before TUR and then before each cystoscopy during follow-up. Screening for the most prevalent FGFR3 mutations was done using urinary cells. The prognostic significance of an FGFR3 mutation at the time of the initial diagnosis was determined. The performance of the test in diagnosing and/or predicting recurrence during follow-up was assessed by calculating sensitivity and specificity. RESULTS: Of 191 patients studied, 74 (39%) had a positive analysis before TUR (FGFR3 mutation group). The presence of an FGFR3 mutation at the time of diagnosis was associated with a shorter time to recurrence (P = .02). During follow-up, 68 patients from the FGFR3 mutation group were evaluated. FGFR3 mutation analysis showed a sensitivity of 0.73 and a specificity of 0.87 when compared with the results of cystoscopy. A positive urine test was predictive of recurrence either at the time of the positive result or later during the 2-year follow-up, with a sensitivity of 0.70 and a specificity of 0.87. CONCLUSION: Among patients with an FGFR3 mutation in the initial tumor, a noninvasive urine test during follow-up can be valuable in diagnosing or predicting subsequent recurrence.

18F-Choline PET/CT and Prostate MRI for Staging Patients With Biochemical Relapse After Irradiation for Prostate Cancer.

PURPOSE: The aim of this study was to assess the value of combining MRI and F-fluorocholine (FCH) PET/CT for patients with a biochemical relapse (BR) after prostate radiotherapy or brachytherapy. PATIENTS AND METHODS: All patients with a BR (BR definition: nadir prostate-specific antigen, +2 ng/mL) had a multiparametric MRI and FCH PET/CT if there was no clinical sign of relapse. Identification of the relapse was considered positive if both imaging techniques were concordant or in case of pathological relapse confirmation. RESULTS: Sixty-five consecutive patients were analyzed. Initial treatment was external beam radiation therapy (EBRT; n = 40), surgery followed by EBRT (n = 11), or brachytherapy (n = 14). Gleason score was 6 in 23 patients, 7 in 35 patients, and 8 to 10 in 7 patients. Median prostate-specific antigen value at the time of relapse was 7.6 ng/mL. Determination of relapse location was identified in 46 patients (70.7%). Relapses were only local in 24 patients (37%), nodal in 16 (24.6%), and distant in 9 (14%). In 4 cases, MRI showed a local relapse not seen by FCH PET/CT. Among the 24 patients with an isolated local relapse, 13 underwent a confirmatory biopsy and 9 were positive. At the end, only 7 patients (11%) could have a salvage local treatment: cryotherapy of the prostate in 6 cases and 1 nodal EBRT. CONCLUSIONS: In case of BR after radiotherapy or brachytherapy, combining MRI and FCH PET/CT could identify the site of relapse in 70% of patients. This could facilitate the selection of the patients for local salvage treatment.

T-helper 1 immunoreaction influences survival in muscle-invasive bladder cancer: proof of concept.

OBJECTIVE: To define immunoscore in bladder cancer studying T helper 1 (Th1) immunoreaction. To define a cancer-specific survival model based on Th1 cells infiltration. METHODS: A total of 252 patients underwent primary transurethral resection of bladder tumour at our Institution. A retrospective review of a selected cohort with pT1 and muscle-invasive bladder cancer (MIBC) lesions was performed. Pathology blocks were marked with CD3 and CD8 antibodies. Immune cells density in stromal reaction (SR) was measured on five distinct high-power field (HPF) by two dedicated uro-pathologist blinded for patients' evolution. STATISTICS: Student test or non-parametric Wilcoxon test as appropriate to compare means between two groups. Receiver operating characteristics (ROC) curve to define markers threshold. Cox model to assess survival's predictors. RESULTS: Ten pT1 and 20 MIBC consecutive cases were analysed. Median follow-up was 33.4 months. Immunohistological analysis for pT1 lesions featured limited SR. For MIBC, the mean density of lymphocytes in the SR was of 105/HPF (CD3) and 86/HPF (CD8). Survivors harboured higher lymphocytes densities versus non survivors (CD3: p = 0.0319; CD8: p = 0.0279). CD3 (p = 0.034) and CD8 (p = 0.034) lymphocytes densities were independently associated with cancer-specific survival on Cox model analyses. The retrospective design and small size of cohorts are the study limitations. CONCLUSIONS: High CD3 and CD8 lymphocytes SR densities are associated with better cancer-specific survival for MIBC. Th1 reaction against the tumour seems to be protective for bladder cancer. Further evaluation is warranted.

Nephron-sparing surgery for renal tumors measuring more than 7 cm: morbidity, and functional and oncological outcomes.

BACKGROUND: The purpose of this study was to evaluate morbidity, functional, and oncological outcomes after NSS in renal tumors > 7 cm. MATERIALS AND METHODS: We retrospectively analyzed data from 168 patients with tumors > 7 cm who were treated using NSS between 1998 and 2012. RESULTS: Imperative and elective indications accounted for 76 (45.2%) and 92 (54.8%) patients, respectively. Major perioperative complications and renal function deterioration occurred in 33 (19.6%) and 51 patients (30.4%), respectively. In multivariate analysis, age older than 60 years (P = .001; hazard ratio [HR], 5) and tumor malignancy (P = .014; HR, 6.7) were prognostic factors for renal function deterioration whereas imperative indication was a risk factor for major postoperative complications (P = .0019; HR, 2.7). In 126 (75%) patients with malignant tumors, after a median follow-up of 30 months (range, 1-254 months), 25 patients (20.2%) died. In multivariate analysis, imperative indication (P = .023; HR, 4.2), positive surgical margin (P = .021; HR, 3.3), and Fuhrman grade > II (P = .013; HR, 3.7) were prognostic indicators for cancer-free survival (CFS). Imperative indication (P = .04; HR, 8.5) and Fuhrman grade > II (P = .04; HR, 3.9) were predictive factors of cancer-specific survival (CSS). In case of elective indication, positive surgical margin, local recurrence, and cancer-related death occurred in 4 (7.6%), 1 (1.1%), and 1 (1.1%) cases, respectively. For elective indication, 5-year estimates of CFS, CSS, and overall survival rates were: 85.7%, 98%, and 93.9%, respectively. CONCLUSION: In this selected population, imperative vs. elective indication status seems to play a critical role in oncologic outcomes. Oncologic results for elective indications are close to those reported with radical nephrectomy.

The learning curve of transrectal ultrasound-guided prostate biopsies: implications for training programs.

OBJECTIVE: To assess the quality of specimens obtained from prostate biopsies performed by urology residents and evaluate the number of procedures required to perform high-quality transrectal ultrasound (TRUS)-guided prostate biopsies. MATERIALS AND METHODS: Between 2006 and 2009, 770 patients underwent TRUS-guided prostate biopsies in our academic center. During the 6 semesters of this period, 24 residents (4 per semester) performed 1 session of 5.6±1.5 procedures each month for a total of 33.6±9 procedures during the study. The first session was performed with a senior urologist. Prostate cancer detection rate and standards of quality (average length of prostatic core biopsy specimens and absence of prostatic tissue) were retrospectively studied between the beginning and the end of each semester. RESULTS: A total of 12,760 biopsy cores were performed for 770 procedures. Mean patient age (64.5±6.1 years), and median prostate-specific antigen (8.7±3.7 ng/mL) were comparable between the study periods. The average length of biopsy cores significantly improved (+10%) from the first (12±2.7 mm) to the last month (13.2±2.1 mm) with a plateau after 12 procedures. Overall, cancer detection rate was 47% and was stable during the semester (41.3% the first month vs 44.1% the last month; P=.39). On univariate and multivariate analysis the mean length of biopsy specimens was associated with the number of procedures (P<.001) and the number of cores performed (P<.001). CONCLUSION: Twelve procedures are necessary to perform high-quality TRUS-guided prostate biopsies without compromising prostate cancer detection. In current training programs, we strongly recommend that residents have direct supervision for a minimum of 12 cases before they are allowed to perform TRUS-guided biopsies with indirect supervision.

Double J stent reduces the efficacy of extracorporeal shock wave lithotripsy in the treatment of lumbar ureteral stones.

INTRODUCTION: We evaluated the effect of the presence of a double J stent on the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of lumbar ureteral stones. MATERIAL AND METHODS: Between January 2007 and February 2012, we performed a retrospective cohort study. Forty-four patients were treated by ESWL for lumbar ureteral stones and included into two groups for the analysis: group 1, non-stented (n = 27) and group 2, stented patients (n = 17). Treatment efficacy was evaluated by abdominal X-ray or CT-scan at 1 month. Stone-free patients and those with a residual stone ≤4 mm were considered to be cured. RESULTS: Mean stone size and density in groups 1 and 2 were 8.2mm/831HU, and 9.7 mm/986HU respectively. Both groups were comparable for age, BMI, stone size and density, number, and power of ESWL shots given. The success rates in groups 1 and 2 where 81.5% and 47.1%, respectively (p = 0.017). There was no difference between the groups for stones measuring 8 mm or less (p = 0.574). For stones >8 mm, the success rates were respectively 76% and 22.2% for groups 1 and 2 (p = 0.030). Logistic regression analysis revealed a higher failure rate when a double J stent was associated with a stone >8 mm (p = 0.033). CONCLUSIONS: The presence of a double J stent affects the efficacy of ESWL in the treatment of lumbar ureteral stones. This effect is significant for stones >8 mm. Ureteroscopy should be considered as the first-line treatment in such patients.

A 970 Hounsfield units (HU) threshold of kidney stone density on non-contrast computed tomography (NCCT) improves patients' selection for extracorporeal shockwave lithotripsy (ESWL): evidence from a prospective study.

UNLABELLED: What's known on the subject? and What does the study add? Stone density on non-contrast computed tomography (NCCT) is reported to be a prognosis factor for extracorporeal shockwave lithotripsy (ESWL). In this prospective study, we determined that a 970 HU threshold of stone density is a very specific and sensitive threshold beyond which the likelihood to be rendered stone free is poor. Thus, NCCT evaluation of stone density before ESWL may useful to identify which patients should be offered alternative treatment to optimise their outcome. OBJECTIVE: • To evaluate the usefulness of measuring urinary calculi attenuation values by non-contrast computed tomography (NCCT) for predicting the outcome of treatment by extracorporeal shockwave lithotripsy (ESWL). PATIENTS AND METHODS: • We prospectively evaluated 50 patients with urinary calculi of 5-22 mm undergoing ESWL. • All patients had NCCT at 120 kV and 100 mA on a spiral CT scanner. Patient age, sex, body mass index, stone laterality, stone size, stone attenuation values (Hounsfield units [HU]), stone location, and presence of JJ stent were studied as potential predictors. • The outcome was evaluated 4 weeks after the ESWL session by NCCT. • ESWL success was defined as patients being stone-free (SF) or with remaining stone fragments of <4 mm, which were considered as clinically insignificant residual fragments (CIRF). RESULTS: • Our survey concluded that 26 patients (52%) were SF, 12 (24%) had CIRF and 12 (24%) had residual fragment on NCCT after a one ESWL treatment. • Stones of patients who became SF or had CIRF had a lower density compared with stones in patients with residual fragments [mean (sd) 715 (260) vs 1196 (171) HU, P < 0.001]. • The Youden Index showed that a stone density of 970 HU represented the most sensitive (100%) and specific (81%) point on the receiver-operating characteristic curve. • The stone-free rate for stones of <970 HU was 96% vs 38% for stones of ≥ 970 HU (P < 0.001). A linear relationship between the calculus density and the success rate of ESWL was identified. CONCLUSION: • The use of NCCT to determine the attenuation values of urinary calculi before ESWL helps to predict treatment outcome, and, consequently, could be helpful in planning alternative treatment for patients with a likelihood of a poor outcome from ESWL.

The use of estramustine phosphate in the modern management of advanced prostate cancer.

UNLABELLED: What's known on the subject? and What does the study add? Estramustine phosphate has anti-tumour properties and it improves patient outcomes if combined with other chemotherapy agents such as docetaxel. The efficacy of estramustine phosphate in selected patients and its safety profile, provided used with any low-molecular-weight heparin support its use as a second-line treatment in hormone-resistant prostate cancer. OBJECTIVES: • Estramustine phosphate is a nitrogen mustard derivative of estradiol-17ß-phosphate and has anti-tumour properties. • Interest in estramustine has been renewed because of the results of clinical studies showing improved patient outcomes if estramustine is combined with other chemotherapy agents such as docetaxel. PATIENTS AND METHODS: • Relevant clinical studies using chemotherapy combinations including estramustine are discussed. • Efficacy and safety outcomes are summarized. RESULTS: • Combination therapy with estramustine and docetaxel can increase PSA response rates, improve quality of life and increase median patient survival compared with chemotherapy regimens that do not include estramustine. • Although the overall tolerability of estramustine is favourable, its use can be associated with an increased risk of thromboembolic events. CONCLUSIONS: • The identification of suitable patient groups and the effective management of the risk of thromboembolism with the adjunct of low-molecular-weight heparins support the use of estramustine as an effective second-line treatment strategy in hormone-resistant prostate cancer. • These promising findings warrant further investigation in a randomized clinical trial.

Is there any evidence of superiority between retropubic, laparoscopic or robot-assisted radical prostatectomy?

PURPOSE: To compare the perioperative, short-term and long-term postoperative results of radical retropubic prostatectomy (RRP), laparoscopic radical prostatectomy (LRP) and robotic assisted laparoscopic prostatectomy (RALP) in the most recent studies evaluable. MATERIALS AND METHODS: Using PubMed we have undertaken a search based on references from major and recent articles with considerable sample sizes. RESULTS: The operative blood loss and the risk of transfusion were lower in the laparoscopic and robotic-assisted approaches. The surgical duration was shorter in the open and robotic group. Regarding the positive margins, continence and potency no substantial differences between the RRP, LRP, and RALP were found. CONCLUSIONS: Our results suggest that no one surgical approach is superior in terms of functional and early oncologic outcomes. Potential advantages of any surgical approach have to be confirmed through longer-term follow-up and adequately designed clinical studies.

Management of adenocarcinoma of the female urethra: case report and brief review.

INTRODUCTION: We present a case of a differentiated adenocarcinoma of the female urethra, which caused dysuria and voiding dysfunction. MATERIALS AND METHODS: A 54-year-old female presented with dysuria and the sensation of incomplete voiding. RESULTS: An ultrasound-guided biopsy showed a urethral carcinoma. A magnetic resonance imaging (MRI) scan showed a high-stage tumor. The patient had a pelvic exenteration. The patient was free of disease after 2 years of follow up. CONCLUSION: Urethral carcinoma is a rare malignancy. A biopsy is necessary to make a diagnosis. MRI is the best imaging for tumor staging. Small tumors are treated with a single modality option including sparing surgery or radiotherapy. Advanced disease should be treated with a multimodality of options including neoadjuvant radiotherapy given concomitantly with chemotherapy followed by surgery.

5A prospective survey of current prostate biopsy practices among oncological urologists.

BACKGROUND: Needle biopsy of the prostate is a common outpatient procedure. In March 2009, the European Association of Urology (EAU) published an updated, evidence-based "Guidelines on Prostate Cancer," including recommendations for this procedure. OBJECTIVE: To survey onco-urology specialists attending the 6th European Section of Oncological Urology (ESOU) meeting in Istanbul, Turkey in January 2009, to assess their biopsy practices and compare them with March 2009 EAU guidelines. DESIGN, SETTING AND PARTICIPANTS: The authors designed a questionnaire and distributed it to 606 conference delegates. It was completed by 298 delegates, of whom 156 were experienced onco-urological specialists. MEASUREMENTS: The survey results from the 156 experienced onco-urologist specialists were analyzed. RESULTS AND LIMITATIONS: Most (59%) of the 156 respondents worked in large (> 20 bed) units, and 76% said urologists always performed the biopsies. Transrectal ultrasound (TRUS)-guided biopsy was the preferred procedure for 78% of respondents. Prostate-specific antigen (PSA) cut-off points of 4 ng/mL, 3.5 ng/mL, 3 ng/mL, and 2.5 ng/ml were used by 42%, 18%, 23%, and 8% of respondents, respectively, to determine whether a biopsy was indicated. A total of 95% of respondents gave patients prophylactic antibiotics. Another of 15% and 17% of respondents did not advise patients to stop taking warfarin or clopidogrel, respectively. A total of 23% of respondents did not give patients pre-procedure anesthesia, while others gave patients periprostatic lidocaine (31% of respondents), topical lidocaine jelly (35%), or general or spinal anesthesia (5.7%). High grade prostatic intraepithelial neoplasia (HGPIN) was considered by 71% of respondents as being a pre-malignant condition requiring a repeat biopsy. If atypical small acinar proliferation (ASAP) was reported, 62% of respondents recommended a repeat biopsy. Magnetic resonance imaging (MRI) was used to help diagnose cancer (53% of respondents), help stage cancer (83%), or help diagnose cancer recurrence (62%). Study limitations include possible difficulties with the English questionnaire. CONCLUSIONS: Many surveyed specialists were not performing prostate biopsies according to March 2009 evidence-based EAU practice guidelines, which could have adverse consequences for patients.

Stage pT0 after radical prostatectomy with previous positive biopsy sets: a multicenter study.

PURPOSE: We analyzed preoperative data, pathological results and followup of pT0 tumors after radical prostatectomy for prostate cancer diagnosed on previous positive biopsy. MATERIALS AND METHODS: At 6 centers a total of 30 of 7,693 radical prostatectomy specimens were classified as pT0 despite prior biopsy proven prostate cancer. No patients were diagnosed after transurethral prostate resection or received neoadjuvant hormonal treatment. All biopsy cores and radical prostatectomy specimens were reanalyzed by a second pathologist. Followup comprised clinical examination and postoperative prostate specific antigen assay at 1 and 3 months, and every 6 months thereafter. RESULTS: Median patient age was 63 years (range 46 to 73). Median preoperative prostate specific antigen was 7.4 ng/ml (range 1.3 to 23). Of the cases 24 were T1c and 6 were T2a. The median number of biopsy cores was 10 (range 6 to 21) with 1 positive (range 1 to 4). On biopsies median tumor length was 1 mm (range 0.3 to 18) and there was tumor in 11.1% (range 3.4% to 64%). In 25 cases (83.3%) there was only 1 positive biopsy. Gleason score was 3 + 3 in 23 cases and less than 6 in 5 with grade 4 in 2. Only 9 cases filled all nonsignificant tumor criteria. Median specimen weight was 61 gm (range 40 to 160). At a median 82-month followup (range 14 to 226) there was no biochemical progression. CONCLUSIONS: After biopsy proven cancer pT0 prostate cancer is an unpredictable pathological finding. Despite its excellent prognosis it has medicolegal repercussions that justify DNA based tissue analysis. There is no evidence that finding focal cancer after extensive prostate resection changes patient prognosis and postoperative treatment.
