Objective
To compare the efficacy of artificial urinary sphincter (AUS) vs retrourethral transobturator sling (RTS) in men with moderate post‐prostatectomy urinary incontinence (PPI) using propensity ...score‐matching analysis to enhance the validity of the comparison (Canadian Task Force classification II‐2).
Patients and methods
Consecutive men with moderate (3–5 pads/day) stress‐prevalent PPI were included if implanted with a RTS (TiLOOP® Male; pfm medical, Köln, Germany) or AUS (AMS800®; Boston Scientific, Boston, MA, USA) since July 2011 to December 2017 and with ≥12 months of follow‐up. Preoperative assessment included 24‐h pad usage, International Consultation on Incontinence Questionnaire‐Short Form (ICIQ‐SF), urethrocystoscopy, and urodynamics if indicated. Propensity score‐matching analysis was based on age, body mass index, Charlson Comorbidity Index, pad usage, previous radiotherapy, and urethrotomy. The primary outcome was at least ‘much improved’ response at 12‐months according to the Patient Global Impression of Improvement questionnaire, without additional PPI surgery or prosthesis explantation.
Results
Of 109 included patients, 70 patients were matched and the study groups were well balanced for the baseline matched variables. The median baseline 24‐h pad usage was four in both groups (P = 0.10), and median follow‐up was 51.2 months for AUS and 47.2 months (P = 0.5) for RTS patients. In the AUS and RTS cohorts, respectively, 33 (94.3%) and 24 (68.6%) patients achieved the primary outcome (P < 0.001), the 0–1 pad/day rates was 94.3% vs 68.6% (P = 0.012) at 12 months, and 91.4% vs 68.6% (P = 0.034) at last follow‐up. At the last follow‐up, the median 24‐h leakage volumes, median ICIQ‐SF scores and satisfaction rates were 0 vs 15 mL (P = 0.017), 4 vs 10 (P = 0.001), and 94.3% vs 68.6% (P = 0.012) in the AUS and RTS cohorts, respectively. There were no significant differences in overall rates of complications and re‐interventions, although Clavien–Dindo Grade III complications (n = 3) occurred only in the AUS group. At sensitivity analysis, the study was reasonably robust to hidden bias.
Conclusion
We found that AUS implantation significantly outperformed RTS in patients with moderate PPI for both subjective and objective outcomes.
Prostate cancer therapy for locally advanced and metastatic diseases includes androgen deprivation therapy (ADT). Second-generation antiandrogens have a role in castration-resistant prostate cancer. ...Nevertheless, some patients do not respond to this therapy, and eventually all the patients became resistant. This is due to modifications to intracellular signaling pathways, genomic alteration, cytokines production, metabolic switches, constitutional receptor activation, overexpression of some proteins, and regulation of gene expression. The aim of this review is to define the most important mechanisms that drive this resistance and the newest discoveries in this field, specifically for enzalutamide and abiraterone, with potential implications for future therapeutic targets. Furthermore, apalutamide and darolutamide share some resistance mechanisms with abiraterone and enzalutamide and could be useful in some resistance settings.
Abstract Objectives Micro-RNAs are a group of small noncoding RNAs with modulator activity of gene expression. Recently, micro-RNA genes were found abnormally expressed in several types of cancers. ...To study the role of the micro-RNAs in human kidney and bladder cancer, we analyzed the expression profile of 245 micro-RNAs in kidney and bladder primary tumors. Methods and materials A total of 27 kidney specimens (20 carcinomas, 4 benign renal tumors, and 3 normal parenchyma) and 27 bladder specimens (25 urothelial carcinomas and 2 normal mucosa) were included in the study. Total RNA was used for hybridization on an oligonucleotide microchip for micro-RNA profiling developed in our laboratories. This microchip contains 368 probes in triplicate, corresponding to 245 human and mouse micro-RNA genes. Results A set of 4 human micro-RNAs ( miR-28, miR-185, miR-27 , and let-7f-2 ) were found significantly up-regulated in renal cell carcinoma ( P < 0.05) compared to normal kidney. Human micro-RNAs miR-223 , miR-26b , miR-221 , miR-103-1 , miR-185 , miR-23b , miR-203 , miR-17-5p , miR-23a , and miR-205 were significantly up-regulated in bladder cancers ( P < 0.05) compared to normal bladder mucosa. Of the kidney cancers studied, there was no differential micro-RNA expression across various stages, whereas with increasing tumor-nodes-metastasis staging in bladder cancer, miR-26b showed a moderate decreasing trend ( P = 0.082). Conclusions Our results show that different micro-RNAs are deregulated in kidney and bladder cancer, suggesting the involvement of these genes in the development and progression of these malignancies. Further studies are needed to clarify the role of micro-RNAs in neoplastic transformation and to test the potential clinical usefulness of micro-RNAs microarrays as diagnostic and prognostic tool.
Multiple sclerosis (MS) is a progressive neurological autoimmune disease with a diverse range of urological symptomatology, and most MS patients experience 1 or more moderate to severe urinary ...symptoms, as well as bladder and/or sexual disorders. Urologists play the director’s role in evaluating and treating these patients. Therefore, identifying the proper evaluation tools and the most suitable therapeutic options for specific patients requires a thorough understanding of this disease process.
Objective
Radical cystectomy with permanent urinary diversion is the gold standard treatment for invasive muscle bladder cancer. Hydronephrosis is common in these patients, but Ultrasound (US) or ...Computed Tomography Urography (CTU) scan are unable to discriminate obstructive from non-obstructive hydronephrosis. We used Diuresis Renography (DR) with F + 10 in seated position (sp) method in the identification of patients with a Uretero-ileal Anastomosis Stricture (UAS) who would benefit from surgical therapy.
Methods
We studied 39 asymptomatic patients, who underwent radical cystectomy and urinary diversion. Based on radiological findings (US, CTU) 44 kidneys were hydronephrotic. All patients underwent a
99m
Tc-MAG3 DR with F + 10(sp) method. We acquired a DR for 20 min with the patient in a seated position. Patient drank 400–500 mL of water at 5 min after tracer injection and received a 20 mg bolus of Furosemide at 10 min during dynamic acquisition. The indices Time to peak, diuretic half time, and 20 min/peak ratio have been evaluated. Retrograde pyelography confirmed UAS in all patients with DR obstructive findings. We repeated DR as follow-up in two subgroups of patients.
Results
DR with F + 10(sp) method showed obstructive findings in 36 out of 44 hydronephrotic kidneys. 6 patients showed non-obstructive findings. 32 patients showed obstructive findings (20 out of 32 developed UAS within 12 months after surgery). Fifteen pts underwent a surgical treatment of UAS. In 1 patient with equivocal findings, we observed an ileo-ureteral reflux.
Conclusions
The DR with F + 10(sp) method in the seated position has a lower uncertain diagnostic rate, compared to the radiological findings of US or CTU, in management of bladder cancer patients with urinary diversion. The semiquantitative indices diuretic half time and 20 min/peak ratio evaluated in a condition of favorable gravity reduce uncertain responses improving interobserver concordance.
Metanephric adenoma (MA) is an uncommon benign renal tumor whose histomorphological aspect resembles that of Wilms’ tumor and papillary renal cell carcinoma. From a diagnostic and therapeutic ...perspective, recognition of this entity is important as it has a more favorable clinical outcome compared with Wilms’ tumor and papillary renal cell carcinoma. MA should not be treated with nephrectomy if the tumor size is small, opting for a conservative treatment. However, the preoperative diagnosis of this disease is extremely challenging. The present study describes a case of this rare disease, showing an ambiguous radiological imaging and that only after a percutaneous biopsy, was defined as a MA and treated with partial nephrectomy. Moreover, the histological diagnosis of this case was partially complicated by the equivocal immunohistochemical analysis showing negativity for BRAF VE1 staining. Only the mutational analysis demonstrated the presence of the BRAF V600K mutation (for the first time described in a case of metanephric adenoma), highlighting the necessity of sequencing in case of MA with negativity for BRAF VE1 clone.
Purpose
The knowledge of periprostatic nerve fiber (pNF) is still incomplete by means of conventional MRI. The purpose of our study was to demonstrate if DTI imaging is able to depict anatomical ...features of pNF.
Methods
For this retrospective study, fifty-six patients (mean age 63.5 years), who underwent 1.5-T prostate MRI, including 32 directions DTI, were enrolled between October 2014 and December 2018. ANOVA test and Student’s
t
-test were performed between the mean values of the number, FA values, and fiber length of pNF between base and mid-gland, mid-gland and apex, base and apex, right and left side, and anterior and posterior face of the prostate. A qualitative analysis was performed to detect the main orientation of pNF through a colorimetric 3D tractographic reconstruction.
Results
The number of pNF showed a decrease from the base (322) to mid-gland (248) and apex (75) (
p
< 0.05). The FA values were higher at base and mid-gland (0.435 and 0.456) compared to the apex (0.313) (p < 0.05). The length of pNF was higher at apex (13.4 mm) compared to base (11.5 mm) and mid-gland (11.7 mm) (
p
< 0.05). The number of pNF was higher on the posterior face compared to the anterior face at base (186 vs 137), (
p
< 0.001). The FA values were higher on the posterior face compared to the anterior face at base (0.452 vs 0.417), mid-gland (0.483 vs 0.429), and apex (0.42 vs 0.382), (
p
< 0.05). The length of the pNF was higher in the posterior (14.7 mm) than in the anterior face (12 mm) at apex (
p
< 0.001). The main orientation of pNF was longitudinal in all patients (56/56, 100%).
Conclusions
DTI imaging has been demonstrated able to depict anatomical features of pNF.
Aims: Multiple sclerosis (MS) is an autoimmune and neurodegenerative disease that is characterized by a great variety symptoms. Most MS patients suffer from neurogenic lower urinary tract symptoms ...(nLUTS) and erectile dysfunctions (ED). The aim this study is to assess the impact of nLUTS and ED on marital relationships in MS patients. Materials and Methods: MS male patients that arrived for our attention were prospectively enrolled in the study. All of the patients were evaluated on an Expanded Disability Status Scale (EDSS), an IIEF-5 for sexual function, an ICIQ-MLUTS for urinary function, and a Dyadic Adjustment Scale (DAS) for marital relationships. The data were analyzed using descriptive and inferential statistical tests in STATA/MP14. Results: The data of 57 male MS patients were eligible. The mean age was 45 (13.7) years, the mean disease duration was 15.49 (7.86) years, and the mean EDSS score was 3.5 (1.89). In total, 33 (57.89%) MS patients reported urine incontinence, of those, 24 (42.11%) reported UUI. The mean DAS score was 74.40 (34.58). The mean IIEF-5 score was 12.40 (8.05). The mean ICIQ-MLUTS score was 71.94 (41.06). The DAS and ICIQ-MLUTS scores were negatively correlated (r = −0.30, p < 0.001). The DAS and IIEF-5 were moderately correlated (r = 0.47, p < 0.001). The DAS and EDSS were strongly correlated (r = −0.72, p < 0.001). A univariate analysis showed that increasing age (p < 0.001), a longer disease duration (p = 0.029), a higher EDSS score (p < 0.001), and a higher ICIQ-MLUTS score (p < 0.001) were all significantly associated with lower DAS scores. Conclusions: This study demonstrated the large negative impact that nLUTS and ED due to MS have on patients’ marital relationships, highlighting the importance of a multidisciplinary approach in MS patients.
Robotic-assisted surgery is the gold standard for performing radical prostatectomy (RARP), with new robotic devices such as Hugo
RAS gaining prominence worldwide.
We report the surgical, ...perioperative, and early postoperative outcomes of RARP using Hugo
RAS.
Between April 2022 and October 2023, we performed 132 procedures using the Montsouris technique with a four-robotic-arm configuration in patients with biopsy-proven prostate cancer (PCa).
We collected intraoperative and perioperative data during hospitalization, along with follow-up data at predefined postoperative intervals of 3 and 6 months.
Lymphadenectomy was performed in 25 procedures, with a bilateral nerve-sparing technique in 33 and a monolateral nerve-sparing technique in 33 cases. The mean total surgery time was 242 (±57) min, the mean console time was 124 (±48) min, and the mean docking time was 10 (±2) min. We identified 17 system errors related to robotic arm failures, 9 robotic instrument breakdowns, and 8 significant conflicts between robotic arms. One post-operative complication was classified as Clavien-Dindo 3b. None of the adverse events, whether singular or combined, increased the operative time. Positive margins (pR1) were found in 54 (40.9%) histological specimens, 37 (28.0%) of which were clinically significant. At 3 and 6 months post-surgery, the PSA levels were undetectable in 94.6% and 92.1% of patients, respectively. Social urinary continence was regained in 86% after 6 months. Limitations of our study include its observational monocentric case-series design and the short follow-up data for functional and oncological outcomes.
Our initial experience highlights the reliability of the Hugo
RAS system in performing RARP. Additionally, we also list problems and solutions found in our daily work.
(1) Background: PTTG1 sustains the EMT process and the invasiveness of several neoplasms. We previously showed the role of nuclear PTTG1 in promoting invasiveness, through its transcriptional target ...MMP2, in seminoma in vitro models. Here, we investigated the key players involved in PTTG1-mediated EMT in human seminoma. (2) Methods: Two seminoma cell lines and four human seminoma tumor specimens were used. E-Cadherin gene regulation was investigated using Western blot, real-time PCR, and luciferase assay. Immunoprecipitation, ChIP, RE-ChIP, and confocal microscopy analysis were performed to evaluate the interplay between PTTG1 and ZEB1. Matrigel invasion and spheroid formation assays were applied to functionally investigate PTTG1 involvement in the EMT of seminoma cell lines. RNA depletion and overexpression experiments were performed to verify the role of PTTG1/ZEB1 in E-Cadherin repression and seminoma invasiveness. E-Cadherin and ZEB1 levels were analyzed in human testicular tumors from the Atlas database. (3) Results: PTTG1 transcriptionally represses E-Cadherin in seminoma cell lines through ZEB1. The cooperation of PTTG1 with ZEB1 has a significant impact on cell growth/invasion properties involving the EMT process. Analysis of the Atlas database of testicular tumors showed significantly lower E-Cadherin levels in seminoma, where PTTG1 showed nuclear staining. Finally, PTTG1 and ZEB1 strongly localize together in the periphery of the tumors. (4) Conclusions: These results strengthen the evidence for a role of PTTG1 in the EMT process in human seminomas through its cooperation with the transcriptional repressor ZEB1 on the E-Cadherin gene. Our data enrich the molecular characterization of seminoma, suggesting that PTTG1 is a prognostic factor in seminoma clinical management.
