RESUMO

BACKGROUND: Salvage radical prostatectomy (sRP) historically yields poor functional outcomes and high complication rates. However, recent reports on robotic sRP show improved results. Our objectives were to evaluate sRP oncological outcomes and predictors of positive margins and biochemical recurrence (BCR). METHODS: We retrospectively collected data of sRP for recurrent prostate cancer after local nonsurgical treatment at 18 tertiary referral centers in United States, Australia and Europe, from 2000 to 2016. SM and BCR were evaluated in a univariate and multivariable analysis. Overall and cancer-specific survival were also assessed. RESULTS: We included 414 cases, 63.5% of them performed after radiotherapy. Before sRP the majority of patients had biopsy Gleason score (GS) ≤7 (55.5%) and imaging negative or with prostatic bed involvement only (93.3%). Final pathology showed aggressive histology in 39.7% (GS ≥9 27.6%), with 52.9% having ≥pT3 disease and 16% pN+. SM was positive in 29.7%. Five years BCR-Free, cancer-specific survival and OS were 56.7%, 97.7% and 92.1%, respectively. On multivariable analysis pathological T (pT3a odds ratio [OR] 2.939, 95% confidence interval [CI] 1.469-5.879; ≥pT3b OR 2.428-95% CI 1.333-4.423) and N stage (pN1 OR 2.871, 95% CI 1.503-5.897) were independent predictors of positive margins. Pathological T stage ≥T3b (OR 2.348 95% CI 1.338-4.117) and GS (up to OR 7.183, 95% CI 1.906-27.068 for GS >8) were independent predictors for BCR. Limitations include the retrospective nature of the study and limited follow-up. CONCLUSIONS: In a contemporary series, sRP showed promising oncological control in the medium term despite aggressive pathological features. BCR risk increased in case of locally advanced disease and higher GS. Future studies are needed to confirm our findings.

RESUMO

BACKGROUND: A 11C-choline positron emission tomography/computed tomography (PET/CT) scan is used for restaging prostate cancer (PCa) patients with biochemical recurrence (BCR). Only a few reports have focused on the correlation between PET/CT and nodal relapse location at pathologic examination. OBJECTIVE: To assess the accuracy of PET/CT in predicting the site of nodal relapses in patients undergoing pelvic and/or retroperitoneal salvage lymph node dissection (sLND). DESIGN, SETTING, AND PARTICIPANTS: Multicentric retrospective study including 106 patients with BCR of PCa after radical treatment; all patients but six had a PET/CT showing at least one nodal recurrence and received sLND. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: PET/CT results were compared with histologic findings and analyzed in terms of sensitivity, specificity, and accuracy. Multivariable regression analyses were performed. RESULTS AND LIMITATIONS: Overall sensitivity, specificity, negative and positive predictive value, and accuracy of PET/CT for disease location were 61.6%, 79.3%, 66.3%, 75.7%, and 70.2%, respectively. Sensitivity was 75.5% in the lower pelvis with 69.8% specificity. The retroperitoneal region had high specificity (94.7%) but a relatively low sensitivity (58.3%). The sLNDs did not find any positive nodes in 16 patients (15%). According to regression analyses, discriminative accuracy of PET/CT was 70.4% and improved with an increased number of dissected nodes and prostate-specific antigen doubling time <12 mo. Limitations include retrospective design and lack of a standardized sLND template followed for all patients. CONCLUSIONS: The ability of PET/CT to detect nodal relapses is limited by a high false-positive rate, particularly in the iliac-obturator region and, more alarmingly, a high false-negative rate in the common iliac, sacral, and retroperitoneal regions. An extended template including pelvic and retroperitoneal regions should be adopted when sLND is planned for curative intent. PATIENT SUMMARY: The 11C-choline positron emission tomography/computed tomography scan is a commonly used tool to restage prostate cancer patients with biochemical recurrence, showing an overall per patient accuracy >80%; however, its ability to detect the site of nodal relapses remains suboptimal.

RESUMO

BACKGROUND: Retrograde intra-renal surgery (RIRS) has become increasingly common and is mainly performed under general anesthesia (GA). There are no specific papers about RIRS performed under spinal anesthesia (SA). Our objective was to evaluate feasibility and results of RIRS performed under SA. METHODS: We analyzed all consecutive RIRS performed for stones in day surgery from March 2008 to September 2012. Single procedures outcomes of RIRS performed under SA were evaluated with US and KUB X-ray at 2 weeks. Further treatments, operative time and complications were also evaluated. Outcomes of RIRS performed under SA and GA were compared. Difference between groups was statistically analyzed. Significance level was set at P<0.05. RESULTS: One hundred thirty-nine RIRS under SA and 47 under GA were considered. Mean stone burden was 14±6 mm. No case of conversion from SA to GA occurred. Stone-free rate (SFR) level 4U of RIRS under SA and under GA were respectively 63.6% and 48.6%, SFR level 0U 24.5% and 25.7%, CIRF 39.1% and 22.9%. Further treatments were performed respectively in 20.8% and in 23.4%. No anesthesia-related and Clavien-Dindo grade ≥3 complications occurred. No statistically significant difference was found in stone-free rates, CIRF and significant residual fragments rates, need for further procedures, operative time and complications between the two groups. CONCLUSIONS: RIRS under SA seems feasible and effective for renal stones in day surgery. Results seem equivalent to RIRS under GA. SA can be considered for RIRS as an alternative to GA.

RESUMO

BACKGROUND AND OBJECTIVES: Renal transplant recipients (RTRs) have a 2- to 7-fold risk of developing a neoplasm compared to general population. Bladder urothelial neoplasms in this cohort has an incidence of 0.4-2%. Many reports describe a more aggressive behavior. The objective of this study is to describe oncologic characteristics of bladder urothelial neoplasms in RTRs and to evaluate its recurrence, progression, and survival rates. METHODS: A retrospective multicentered study was performed evaluating all de novo bladder urothelial neoplasms cases in RTRs from 1988 to 2014. Descriptive statistical analysis and evaluation of recurrence, progression, and survival rates were performed. RESULTS: A total of 28 de novo bladder transitional cell carcinomas (TCCs) were identified (incidence rate 0.64%). Cancer-specific survival rates were 100, 75, and 70% after 1, 5, and 10 years, respectively. Age at diagnosis superior to 60 years was found to be a statistically significant variable for recurrence risk. Progression rate was 14%. Presence of CIS was significantly associated with progression. All cancer-specific deaths were in the high-risk group and all were progressions from non-muscle invasive to muscle invasive bladder cancer. CONCLUSIONS: Bladder urothelial neoplasms following renal transplant is associated with a trend toward worst prognosis. Early aggressive treatments, such as early radical cystectomy, might be advisable to reduce cancer-specific deaths.

RESUMO

OBJECTIVE: Targeted fusion biopsies have led to an improved prostate cancer (PCa) detection rate (CDR). Our aim was to assess if device-assisted fusion biopsies are superior to cognitive ones in terms of CDR. The association between multiparametric MRI parameters and PCa was also evaluated. METHODS: We retrospectively enrolled 50 patients who underwent transrectal biopsy with elastic fusion (Koelis; group KB, n = 25) or cognitive approach (group CB, n = 25). Targeted biopsies were done on targets, while a variable number of random biopsies were performed depending on the clinical case. RESULTS: The groups did not significantly differ in terms of age, prostate-specific antigen, prostate volume and previous biopsies. Mean number of random cores was significantly inferior in KB group (8.4 vs. 12.1) and mean number of targeted biopsies was significantly higher (3.6 vs. 2.6). CDR was higher in fusion biopsies (64 vs. 40%), with the gap becoming significant when considering CDR of MRI targets only (59 vs. 27%). The difference was marked for lesions ≤10 mm, where CDR was 52% in KB against 21% in CB group. CONCLUSIONS: According to our study, elastic fusion biopsies performed with Koelis achieve an increased per-patient and per-lesion CDR as compared to cognitive biopsies, especially in the case of lesions ≤10 mm.

RESUMO

Even though CT scans are considered the gold standard to characterize a renal mass, sometimes they can be misleading, showing a solid renal mass as a cystic one. Tubulocystic renal cell carcinoma (TcRCC) is a rare and recently discovered RCC variant which radiologically may look like a Bosniak type II to IV, even if it has solid features. We describe a case of a patient with left kidney TcRCC initially diagnosed as a renal cyst, who finally underwent radical nephrectomy showing a large, solid neoplasm. Due to its unusual CT appearance, TcRCC can be confused with cystic lesions and several other benign or malignant entities. Ultrasound can be a useful aid for the characterization of these renal tumors.

RESUMO

Renal transplant (RT) represents the treatment of choice for end-stage renal disease (ESRD) but harbours a wide range of possible complications and therapeutic challenges of urological competence. Dialysis years and clinical medical background of these patients are risk factors for sexual dysfunction and lower urinary tract symptoms (LUTS). On the contrary, RT itself may have a number of possible surgical complications such as ureteral stenosis and urinary leakage, while immunosuppressive treatment is a known risk factor for de-novo malignancies.The present review describes the main urologic problems of RT patients and their up-to-date treatment options according to the most recently available literature evidences.

RESUMO

OBJECTIVE: Some patients with the indication of radical prostatectomy (RP) have often undergone previous surgical treatment for bladder outlet obstruction (BOO). These previous treatments make oncological surgery more challenging because of the difficulty in the identification of bladder neck and ureteral orifices. We present a new technique that entails previous endoscopic marking of bladder neck in order to make radical prostatectomy easier. METHODS: Twelve men with previous prostatic surgery for BOO underwent a laparoscopic/robotic radical prostatectomy between August 2008 and October 2012. The same technique was performed in all cases, a first circular endoscopic incision (EI) to mark the bladder neck and a second laparoscopic/robotic approach to complete the RP. We analyzed oncological and functional outcomes, as well as complications. RESULTS: Median operative time (EI + RP) was 175 minutes (140-205), being surgical time for endoscopic approach 20 minutes (17-31). No ureteral lesions were described and no ureteral stents were required. Positive margin rate was 8.3%. Only 1 of 5 complications observed needed surgery to be solved. Continence rate was 66.7% at one year of surgery. CONCLUSIONS: Our results show that a previous endoscopic bladder neck incision in patients with previous surgery for BOO makes easier the identification and dissection of the bladder neck itself during radical prostatectomy decreasing the risk of ureteral lesions as well as improving functional outcomes.

RESUMO

OBJETIVO: Algunos de los pacientes a los que indicamos prostatectomía radical (PR) han sido sometidos a cirugía prostática previa por obstrucción cérvico-uretral (OCU). Este hecho dificulta la cirugía oncológica por la dificultad en la disección del cuello vesical y el riesgo de lesionar los meatos ureterales. Presentamos una técnica que consiste en realizar una incisión endoscópica previa en el cuello vesical con el fin de facilitar la prostatectomía radical. MÉTODOS: Doce pacientes con cirugía previa por OCU fueron sometidos a PR entre Agosto del 2008 y Octubre del 2012. La técnica empleada en todos los casos fue la misma, un primer tiempo endoscópico realizándose incisión endoscópica (IE) circunferencial para marcar el cuello vesical y un segundo tiempo laparoscópico/ robótico para completar la PR. Se analizaron resultados oncológicos y funcionales así como las complicaciones. RESULTADOS: La mediana del tiempo quirúrgico (IE+PR) fue de 175 (140-205) minutos, siendo la mediana de tiempo de la cirugía endoscópica 22 (17-31) minutos. No se describió en ningún caso lesiones a nivel de los meatos ureterales ni fue necesario cateterismo ureteral. La tasa de márgenes positivos fue del 8,3%. De las 5 complicaciones descritas, sólo una requirió de tratamiento quirúrgico. La continencia fue del 66,7% al año de la intervención. CONCLUSIONES: La realización de una incisión endoscópica en el cuello vesical, en pacientes con cirugía previa por OCU ha demostrado ser una buena estrategia como primer paso en la PR para conseguir buenos resultados oncológicos y funcionales junto con una baja tasa de complicaciones

RESUMO

INTRODUCTION: Although several new measurements for female sexual dysfunction (FSD) have recently been developed, the Female Sexual Function Index (FSFI) remains the gold standard for screening and one of the most widely used questionnaires. The Italian translation of the FSFI has been used in several studies conducted in Italy, but a linguistic validation of the Italian version does not exist. AIM: The aim of this study was to perform a linguistic validation of the Italian version of the FSFI. METHODS: A multicenter cross-sectional study conducted in 14 urological and gynecological clinics, uniformly distributed over Italian territory. We performed all steps necessary to determine the reliability and the test-retest reliability of the Italian version of the FSFI. The study population was a convenience sample of 409 Italian women. MAIN OUTCOME MEASURES: The reliability of the questionnaire was calculated using Cronbach's alpha, which was considered weak, moderate, or high if its value was found less than 0.6, between 0.6 and 0.8, or equal to or greater than 0.8, respectively. The test-retest reliability was assessed for all women in the sample by calculating Pearson's concordance correlation coefficient for each domain and for the total score, both at baseline and after 15 days (r range between -1.00 to +1.00, where +1.00 indicates the strongest positive association). RESULTS: Cronbach's alpha coefficients for total and domain score were sufficiently high, ranging from 0.92 to 0.97 for the total sample. The test-retest procedure revealed that the concordance correlation coefficient was very high both for FSFI-I total score (Pearson's P = 0.93) and for each domain (Pearson's P always >0.92). CONCLUSION: For the first time in the literature, our study has produced a validated and reliable Italian version of the FSFI questionnaire. Consequently, the Italian FSFI can be used as a reliable tool for preliminary screening for female sexual dysfunction for Italian women.

RESUMO

PURPOSE: To describe a new geometrical stepper-guided navigation system for positioning ProACT®. METHODS: The sizing of the stepper-guided navigation system was calculated using the distance from the ideal position of the device to anatomic referral points previously measured by ultrasound. The trocar and subsequently the device were maneuvered to the ideal position in accordance with the navigation system. MEASUREMENTS: Treatment efficacy was evaluated with daily pad count, 1-hour pad test, Incontinence Quality of Life questionnaire (IQoL), visual analog scale and overall impression. Complications, balloon volume and number of adjustments were reported at 1, 3, 6 and 12 months follow-up visits. RESULTS: Mean follow-up was 12 (range 3-19) months. Daily pad count showed 30 patients (71%) dry and 9 patients (21%) improved. 1 hour pad test showed 28 patients were dry (66%) and 11 patients improved (26%). IQoL increased from an average of 35.3 to 80. Average visual analog scale score was 8. Complications requiring device removal occurred in 3 patients (7%). Mean balloon volume was 3.1 ml. CONCLUSIONS: The stepper-guided navigation system to implant ProACT is feasible and extremely reproducible making this procedure more standardized.
