ABSTRACT

PURPOSE: To evaluate the neurovascular bundle preservation grades during robotic-assisted radical prostatectomy and compared to the trifecta combined outcome (oncologic control, continence, and sexual function) twelve months after the surgery. METHODS: Cohort of patients who underwent nerve-sparing robotic-assisted radical prostatectomy had the neurovascular bundle preservation retrospectively graded from 0 to 8 according to the Hopkins subjective visual classification. Patients then were divided into two groups, according to the median of nerve-sparing grading: those with score six or high and those with score less than six. Main outcome was the trifecta combined outcome and secondary outcomes was the individual trifecta criteria (prospective analysis). A secondary analysis with groups divided according to pre-operatory SHIM score was made. RESULTS: One hundred robotic-assisted nerve-sparing radical prostatectomy were performed, of which 83 were included. There were 53 patients with grading greater than or equal to six (group 1) and 30 patients less than six (group 2). 66.6% patients (35/53) in group 1 had a trifecta combined outcome of compared to 33.3% (10/30) in group 2 (p = 0.017). Individually, the erectile function was higher in group 1 (73.6%) compared to group 2 (46.7%) (p = 0.014). Both the results of the combined endpoint trifecta and erection were also maintained in the group with preoperative SHIM ≥ 17. CONCLUSIONS: The grading of preservation of the neurovascular bundle in radical prostatectomy is related to a better combined trifecta outcome one year after surgery.

ABSTRACT

INTRODUCTION: There is no information about the evolution of robotic programs in public hospitals of Latin-America. OBJECTIVE: To describe the current status and functioning of robotic programs in Latin-American public hospitals since their beginning to date. METHODS: We conducted a survey among leading urologists working at public hospitals of Latin-America who had acquired the Da Vinci laparoscopic-assisted robotic system. Questions included: date the program started, its utilization by other services, number and kind of surgeries, surgery paying system, surgery related deaths, occurrence and reasons of robotic program interruptions and its use for training purposes. Medians and 25-75 centiles (IQR) were estimated. RESULTS: Since 2009, there are ten public hospitals of four Latin-American countries that acquired the Da Vinci robotic system. The median number of months robotic programs has been functioning without considering transitory interruption: 43 (IQR 35, 55). Median number of urologic and total surgeries performed: 140 (IQR 94, 168) and 336 (IQR 292, 621), respectively. The corresponding median number of urologic and total surgeries performed per month: 3 (IQR 2, 5) and 8 (IQR 5, 11). Median number of total surgeries performed per year per institution was 94 (IQR 68,123). The median proportion of urologic cases was 40% (IQR 31, 48), ranging from 24 to 66%. Five of ten institutions had their urology programs transitory or definitively closed due to the high burden costs. CONCLUSION: Adoption and development of robotic surgery in some public hospitals of Latin-America have been hindered by high costs.

ABSTRACT

Interleukin-8 (IL-8) is an angiogenic CXC chemokine that plays an important role in both the development and progression of several human malignancies including prostate cancer (PC). A single nucleotide polymorphism (SNP) at -251 upstream of the transcriptional start site of the IL-8 gene has been shown to influence its production. The effects of IL-8 are mediated by two highly related chemokine receptors, CXCR1 and CXCR2. The present study investigated the influence of the IL-8 and CXCR2 gene variation on susceptibility and clinicopathological characteristics of PC in a group of Brazilian subjects. METHODS: Two hundred and one patients and 185 healthy controls were enrolled in a case-control study. Blood was collected for DNA extraction; typing of IL-8 -251 T/A and CXCR2 +1208 C/T genes was performed by polymerase chain reaction with sequence-specific primers (PCR-SSP), followed by agarose gel electrophoresis. Risk association between the genotypes, PC susceptibility and tumor characteristics was estimated by odds ratio (OR) and 95% confidence intervals (95% CI) using logistic regression analysis, after adjusting for age at diagnosis. RESULTS: A significant association was found between the heterozygous CXCR2 +1208 CT genotype and stage of PC. The CXCR2 +1208 CT genotype was significantly less frequent in patients with clinical stage T3-T4 compared to T1-T2 (56.7 versus 80.5%). Our findings suggest that carriers of the CXCR2 +1208 CT genotype had a protective effect for advanced PC (CT versus CC: adjusted OR=0.25; P=0.02). No association was observed between the SNP for IL-8 -251 T/A and clinicopathological parameters of PC. CONCLUSION: These results indicated that the CXCR2 +1208 CT genotype is less frequent in advanced stages of PC, suggesting that this chemokine receptor plays a role in the pathogenesis of this disease.

ABSTRACT

INTRODUCTION: The ideal vaginoplasty method should promote good cosmetic and functional results with low morbidity. We describe a new technique for congenital vaginal agenesis using a full-thickness perforated skin graft. MATERIALS AND METHODS: We report an 18 year old patient with vaginal agenesis (Morris syndrome) that undergone a modified version of McIndoe vaginoplasty. Patient is set in a low lithotomy position and lateral traction sutures are placed in labia and a 16Fr urethral catheter inserted. An inverted "V"-shaped incision is made in the mucosal plaque below the urethra. Blunt dissection in a cephalic posterior direction forms a space between the rectum and urethra. Special care is taken to avoid rectal tear during this maneuver. A full-thickness skin graft is removed from the lower abdomen measuring 12.0x6.0cm as an aesthetic abdominoplasty. The fat tissue is removed, remaining epidermis and dermis and the graft is perforated, allowing a great surface increase. After suturing over a mold, the graft is fixed in the created space. The donor site is closed with intradermal transversal suture. RESULTS: From January 2009 to August 2015, seven patients diagnosed with vaginal agenesis underwent this technique. There were no major complications or need for blood transfusions. At the six-month follow-up, all patients reported satisfactory sexual intercourse. There were no significant complications at donor site or neovagina that needed surgical intervention. CONCLUSION: Vaginal reconstruction using the perforated graft is viable with excellent functional results. Applying this modification, we yielded the good results of a classic McIndoe technique with lower donor site morbidity.

ABSTRACT

PURPOSE: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. MATERIALS AND METHODS: We prospectively collected data from consecutive patients that underwent RARP. Patients with at least 6 months of follow-up were included in the analysis for the following outcomes: time to complete VUA, continence and complications related to anastomosis. Nerve-sparing status, age, BMI, EBL, pathological tumor staging, and prostate size were evaluated as possible factors predicting early and midterm continence. Results were compared with current literature. RESULTS: Data from 60 patients was assessed. Mean time to complete VUA was 34 minutes, and console time was 247 minutes. Continence in 6 months was 90%. Incidence of urinary leakage was 3.3%, no patients developed bladder neck contracture or postoperative urinary retention. On multivariate analysis, age and pathological staging was associated to 3-month continence status. CONCLUSION: Our data show that, during early experience with RARP in a public university hospital, it is possible to achieve good results regarding continence and other outcomes related to VUA. We also found that age and pathological staging was associated to early continence status.

ABSTRACT

OBJECTIVES: To assess patient satisfaction and quality of life after urethroplasty using two different self-reported outcome measures and to compare it with objective clinical data. MATERIALS AND METHODS: We prospectively collected data from 35 consecutive patients who underwent urethroplasty from January 2013 to September 2014. Patient demographics, International Prostate Symptom Score (IPSS), quality of life score, urethral stricture surgery patient-reported outcome measure (USS-PROM), maximum flow rate (Qmax) and post-void residual urine were collected before, two and eight months after surgery. Failure occurred when any postoperative instrumentation was performed. General estimation equation was used to compare the results and linear regression analysis to correlate both questionnaires with objective data. RESULTS: Mean age was 61 years. Urethroplasties were equally divided between anastomotic and buccal mucosa grafts and 19 patients (59.3%) had a previous urethral procedure. Overall success rate was 87.5%. IPSS improved from a mean 19 at baseline to 5.32 at 8 months (p < 0.001). The mean USS-PROM score also improved from 13.21 preoperatively to 3.36 after surgery (p< 0.001) and 84.3% of patients were satisfied or very satisfied with surgical results. Mean Qmax increased from 4.64mL/s to 11mL/s (p< 0.001). Strong negative correlation was found respectively between flow rate and USS-PROM (r=-0.531, p< 0.001) and with IPSS (r=-0.512, p < 0.001). CONCLUSIONS: Significant improvements in urinary symptoms and in quality of life are expected after urethroplasty and they are correlated with objective measures.

ABSTRACT

INTRODUCTION: Ganglioneuromas are rare benign neoplasms of the sympathetic nervous system. We describe the case of an incidentally found ganglioneuroma in a woman. To our knowledge this is the first described case of robotic excision of a retroperitoneal ganglioneuroma. CASE: A 41-year-old female had an incidental retroperitoneal mass found during a routine US. CT scan and MRI showed an 8.3cm homogeneous mass, adjacent to left kidney upper pole, with peripheral contrast enhancement. Metabolic tests were normal. Patient was positioned in a left flank position and five ports were introduced transperitoneally. A 4-arm Da Vinci SI was docked at a 45º angle to the table. Lesion was dissected along with left adrenal gland, beginning at the left renal hilum and proceeding cephalad. RESULTS: Operating time was 325min and blood loss was 50ml. Patient was discharged after 72hours. There were no post-operative complications. Pathology showed ganglionic cells with neural tissue, and normal adrenal. DISCUSSION: Ganglioneuromas rare benign tumors originating from neural crest and typically affect young adults. Most frequent locations are posterior mediastinum, retroperitoneum and adrenal gland. As in this case, ganglioneuromas are usually silent, slow growing tumors discovered incidentally or by mass effect. US and CT imaging may suggest the diagnosis while MRI findings can be specific for ganglioneuroma. Percutaneous biopsy is an option. Although benign, usually requires surgical excision for treatment. CONCLUSIONS: Our case shows that a robotic approach is feasible and allows for meticulous and safe dissection of vascular structures, facilitating adequate hemostasis while maintaining oncological principles.

ABSTRACT

Selection of reference genes to normalize mRNA levels between samples is critical for gene expression studies because their expression can vary depending on the tissues or cells used and the experimental conditions. We performed ten cell cultures from samples of prostate cancer. Cells were divided into three groups: control (with no transfection protocol), cells transfected with siRNA specific to knockdown the androgen receptor and cells transfected with inespecific siRNAs. After 24 h, mRNA was extracted and gene expression was analyzed by Real-time qPCR. Nine candidates to reference genes for gene expression studies in this model were analyzed (aminolevulinate, delta-, synthase 1 (ALAS1); beta-actin (ACTB); beta-2-microglobulin (B2M); glyceraldehyde-3-phosphate dehydrogenase (GAPDH); hypoxanthine phosphoribosyltransferase 1 (HPRT1); succinate dehydrogenase complex, subunit A, flavoprotein (Fp) (SDHA); TATA box binding protein (TBP); ubiquitin C (UBC); tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, zeta polypeptide (YWHAZ)). Expression stability was calculated NormFinder algorithm to find the most stable genes. NormFinder calculated SDHA as the most stable gene and the gene with the lowest intergroup and intragroup variation, and indicated GAPDH and SDHA as the best combination of two genes for the purpose of normalization. Androgen receptor mRNA expression was evaluated after normalization by each candidate gene and showed statistical difference in the transfected group compared to control group only when normalized by combination of GAPDH and SDHA. Based on the algorithm analysis, the combination of SDHA and GAPDH should be used to normalize target genes mRNA levels in primary culture of prostate cancer cells submitted to transfection with siRNAs.

ABSTRACT

Polymorphic GGC repeats in the androgen receptor (AR) gene can alter transactivation of androgen-responsive genes and increase the risk of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). We investigated the association between GGC repeat length, testosterone levels and the risk of developing PCa and BPH in a population from southern Brazil. A sample comprising 130 PCa, 126 BPH and 88 control patients was evaluated. DNA was extracted from leukocytes and the AR gene was analyzed by fragment analysis. The hazard ratio (HR) was estimated. GGC mean length was not different between the three study groups. The risk of developing PCa in individuals with GGC > 19 was 3.300 (95 %CI 1.385-7.874) higher when compared to the GGC ≤ 19 group (p = 0.007). The risk of developing PCa and BPH in individuals with total testosterone levels <4 ng/mL was 2.799 (95 % CI 1.362-5.754). (p = 0.005) and 2.786 (95 % CI 1.470-5.280) (p = 0.002), respectively. Total testosterone levels in patients with GGC > 19 were significantly lower when compared to patients in the GGC ≤ 19 group. Our data suggest that the presence of a high number of polymorphic GGC repeats in the AR gene is associated with an increased risk of developing PCa and BPH, and that lower testosterone levels also increase the risk of developing these diseases.

ABSTRACT

BACKGROUND: Partial nephrectomy (PN) is the preferred modality of treatment for small renal masses. Laparoscopic partial nephrectomy (LPN) has been adopted worldwide and a fundamental role is played by surgical skills. The need for skill instruction outside the operating room is well recognized in the modern models of surgery residency training. We aim to investigate the impact of residents' laparoscopic surgical skills training on the successful implementation of LPN in a reference public teaching hospital in southern Brazil. METHODS: We accessed all patients undergoing LPN by senior's urology residents at Hospital de Clínicas de Porto Alegre. Patients were stratified in 2 periods of time named 'LPN eras' 1 and 2, to report the training impact on the outcome. LPN era 1 was from October 2012 to February 2017 and LPN era 2 from March 2017 to June 2019. All the senior residents of LPN era 2 followed a simulation training divided into 4 years with a total training time of 244 hours before performing the LPN. Residents from LPN era 1 did not have simulation training. RESULTS: 124 patients underwent LPN during the study period, 53 (42.7%) of those were performed in LPN era 1 and 71 (57.3%) in LPN era 2. Baseline characteristics of the patients in the two groups were similar. The training performed by LPN era 2 residents was able to significantly reduce estimated blood loss, ischemia time and LOS with p value respectively 0.007, 0.001 and 0.001. LPN era 2 group also reached Trifecta in 77.5% of patients, being significantly more than in the LPN era 1 (p = 0.007). CONCLUSIONS: Simulation in residents surgical training was able to improve clinical outcomes in LPN. These data reinforce the fundamental importance of adequate residents training before performing surgery on a patient.

ABSTRACT

OBJECTIVE: To describe various approaches for ureterolysis with an omental wrap using minimally invasive techniques, as surgery for idiopathic retroperitoneal fibrosis includes tissue biopsy, ureterolysis, and intraperitonealization or omental wrap. PATIENTS AND METHODS: Since 2006 we have performed ureterolysis in four patients diagnosed with retroperitoneal fibrosis in two institutions. The ureterolysis in two cases was bilateral, using a standard laparoscopic approach for one case and a hand-assisted technique for the other. Unilateral ureterolysis was completed using a standard laparoscopic approach in one case and was converted to a hand-assisted technique in the other due to difficulty with ureteric identification. An omental wrap was used after ureterolysis for all renal units. RESULTS: A minimally invasive technique was used for all ureterolysis procedures and none required open conversion. There was fascial dehiscence after surgery at the hand-port site in one patient, and required re-operation for wound closure. The median (range) hospital stay for all patients was 2.5 (2-10) days and the median blood loss was 100 (50-550) mL. No patient required a blood transfusion. At a median 16.5 (12-32) months of follow-up, there was symptomatic and radiographic success in all patients. CONCLUSIONS: Ureterolysis can be a challenging operation depending on the extent of the retroperitoneal mass. An understanding of various laparoscopic techniques can provide the flexibility for successful completion of nearly all of these procedures using a minimally invasive approach.

ABSTRACT

PURPOSE: To attempt the isolation and primary culture of prostate tumor cells, to use the cultured cells for active immunotherapy, and to evaluate the safety and efficacy in a Phase I clinical trial. MATERIALS AND METHODS: Tumor fragments were collected from 50 patients with prostate-specific antigen (PSA) > or = 10 ng/mL, < or = cT2 PCa who underwent radical retropubic prostatectomy (RRP) and 6 patients with metastatic PCa who underwent transurethral resection of the prostate (TURP). Cultured tumor cells were incubated with IFN-fi, irradiated, and cryopreserved. Seven vaccine inoculations were performed into > or = pT3 and/or N+ patients, and M+ patients, with the first two doses admixed with Bacille Calmette-Guerin (BCG). Follow-up was performed with measurement of delayed-type hypersensitivity (DTH) reactions, PSA and hemato-chemical tests, and bone scans. RESULTS: No cell culture was obtained in the TURP group. Cell culture and vaccine production were obtained in 37 cases (74%) in the RRP group. Eleven > or = pT3 and/or N+ patients were vaccinated. Toxicity was generally limited to the inoculation sites. DTH reactions > or = 10 mm were observed in 2 patients and > or = 5 mm in 6 patients. Two patients had a decrease in PSA levels after vaccine administration. CONCLUSIONS: The autologous cell vaccine is safe and seems to induce a positive immune cellular response. Primary cell culture and vaccine production can be obtained for most RRP patients, but not for TURP patients using our method. There seems to be some influence of the vaccine in PSA evolution after RRP.

ABSTRACT

OBJECTIVE: To present a novel technique in reconstructive urology for congenital vaginal agenesis using a full-thickness mesh skin graft and to evaluate the functional capacity for maintenance of satisfactory intercourse. METHODS: From January 2009 to August 2015, seven patients diagnosed with vaginal agenesis underwent vaginoplasty using a full-thickness mesh graft from lower abdominal skin. Herein, the authors describe the technique and initial results in adult patients. RESULTS: The mean hospital stay was 8 days. There were no major complications or need for blood transfusions. The most relevant postoperative result was the functionality of the neovagina and satisfactory donor site results. At 6-month follow-up, all patients reported satisfactory sexual intercourse. The average depth of the vagina was 11.3 cm. There were no significant complications at donor site or at neovagina that needed surgical intervention. CONCLUSION: We obtained positive functional results with minimal donor site morbidity by performing vaginal reconstruction using a full-thickness mesh skin graft.

ABSTRACT

Introduction: Renal cell carcinoma (RCC) is one of the most prevalent kidney tumors. Inflammation is believed to be a key factor in its progression and spread since inflammatory markers are generally associated with poor prognosis in RCC patients. Cytokines are cell communication molecules involved in both healthy and pathological processes, including tumor growth and progression. Recent findings suggest that cytokine level measurements could be used for cancer monitoring and prognosis. Methods: This study characterized and compared the levels of different cytokines associated with the classical Th1, Th2, and Th17 immune responses in plasma samples from RCC patients (n = 25) and healthy controls (n = 29). Cytokine levels (IL-2, IL-4, IL-6, IL-10, TNF-α, IFN-γ, and IL-17A) were evaluated by flow cytometry using a BD Cytometric Bead Array (CBA) kit. Results: No statistical differences in systemic IL-2, IL-4, IL-10, IL-17A, TNF, and INF-γ levels were observed between RCC patients and controls (p > 0.05). However, higher systemic IL-6 levels were observed in RCC patients (p = 0.0034). Conclusions: This study highlights the importance of assessing the impact of IL-6 on RCC pathogenesis and its potential role as a biomarker of disease progression. (AU)

ABSTRACT

BACKGROUND: We carried out a case-control study in patients with type 2 diabetes mellitus (T2DM) to evaluate the association between seven single nucleotide polymorphisms (SNPs) previously described to be linked to diabetic kidney disease (DKD) in type 1 diabetes mellitus (T1DM). Additionally, we evaluated gene and protein expression related to the polymorphism associated with DKD. METHODS: The association study included 1098 T2DM patients (718 with DKD and 380 without DKD). Out of the 13 polymorphisms associated with DKD in a previous study with T1DM, seven were chosen for evaluation in this sample: rs1888747, rs9521445, rs39075, rs451041, rs1041466, rs1411766 and rs6492208. The expression study included 91 patients who underwent nephrectomy. Gene expression was assessed by RT-qPCR and protein expression in kidney samples was quantified by western blot and it localization by immunohistochemistry. RESULTS: The C/C genotype of rs1888747 SNP was associated with protection for DKD (OR = 0.6, 95 % CI 0.3-0.9; P = 0.022). None of the other SNPs were associated with DKD. rs1888747 is located near FRMD3 gene. Therefore, FRMD3 gene and protein expression were evaluated in human kidney tissue according to rs1888747 genotypes. Gene and protein expression were similar in subjects homozygous for the C allele and in those carrying the G allele. CONCLUSIONS: Replication of the association between rs1888747 SNP and DKD in a different population suggests that this link is not the result of chance. rs1888747 SNP is located at the FRMD3 gene, which is expressed in human kidney. Therefore, this gene is a candidate gene for DKD. However, in this study, no rs1888747 genotype or specific allele effect on gene and/or protein expression of the FRMD3 gene was demonstrated.

ABSTRACT

Povidone-iodine sclerosis has been suggested in the literature as a safe and effective treatment for post-renal transplant lymphoceles. No significant complications of this method have been described. We report on a kidney allograft recipient with recurrent lymphoceles treated with povidone-iodine instillations who developed acute renal failure secondary to iodine intoxication. Four days after the beginning of the povidone-iodine irrigations, metabolic acidosis was present, and renal function started to deteriorate. After a few days, despite the suspension of irrigations, the patient developed oliguria, and dialysis was needed. A renal biopsy was performed, and intense acute tubular necrosis was the only relevant finding. The lymphocele was corrected surgically, and the patient eventually recovered. As has been described in other settings, povidone-iodine instillation for the treatment of post-renal transplant lymphoceles may lead to iodine kidney toxicity and acute renal failure.

ABSTRACT

Non-ischemic priapism in children is an uncommon entity usually related to blunt trauma in the perineal region and subsequent fistula formation into the corpus cavernosum. In this report we present the case of a 7-year-old boy who had undergone perineal trauma and developed non-ischemic priapism confirmed radiologically. He was treated by conservative measures along with ultrasonographic monitoring. We discuss the diagnostic approach, the radiologic findings and the mainly conservative management of this infrequent pathology.

ABSTRACT

ABSTRACT Objectives To assess patient satisfaction and quality of life after urethroplasty using two different self-reported outcome measures and to compare it with objective clinical data. Materials and Methods We prospectively collected data from 35 consecutive patients who underwent urethroplasty from January 2013 to September 2014. Patient demographics, International Prostate Symptom Score (IPSS), quality of life score, urethral stricture surgery patient-reported outcome measure (USS-PROM), maximum flow rate (Qmax) and post-void residual urine were collected before, two and eight months after surgery. Failure occurred when any postoperative instrumentation was performed. General estimation equation was used to compare the results and linear regression analysis to correlate both questionnaires with objective data. Results Mean age was 61 years. Urethroplasties were equally divided between anastomotic and buccal mucosa grafts and 19 patients (59.3%) had a previous urethral procedure. Overall success rate was 87.5%. IPSS improved from a mean 19 at baseline to 5.32 at 8 months (p <0.001). The mean USS-PROM score also improved from 13.21 preoperatively to 3.36 after surgery (p <0.001) and 84.3% of patients were satisfied or very satisfied with surgical results. Mean Qmax increased from 4.64mL/s to 11mL/s (p <0.001). Strong negative correlation was found respectively between flow rate and USS-PROM (r=-0.531, p <0.001) and with IPSS (r=-0.512, p <0.001). Conclusions Significant improvements in urinary symptoms and in quality of life are expected after urethroplasty and they are correlated with objective measures.

ABSTRACT

ABSTRACT Purpose: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. Materials and Methods: We prospectively collected data from consecutive patients that underwent RARP. Patients with at least 6 months of follow-up were included in the analysis for the following outcomes: time to complete VUA, continence and complications related to anastomosis. Nerve-sparing status, age, BMI, EBL, pathological tumor staging, and prostate size were evaluated as possible factors predicting early and midterm continence. Results were compared with current literature. Results: Data from 60 patients was assessed. Mean time to complete VUA was 34 minutes, and console time was 247 minutes. Continence in 6 months was 90%. Incidence of urinary leakage was 3.3%, no patients developed bladder neck contracture or postoperative urinary retention. On multivariate analysis, age and pathological staging was associated to 3-month continence status. Conclusion: Our data show that, during early experience with RARP in a public university hospital, it is possible to achieve good results regarding continence and other outcomes related to VUA. We also found that age and pathological staging was associated to early continence status.
