Argus-T adjustable male sling:A follow-up study on urinary incontinence and patient's satisfaction

Aims: The use of Argus-T adjustable sling may be a promising alternative option for the treatment of urinary incontinence after radical prostatectomy, however long-term data is lacking. The aim of this study is to evaluate the long-term results of the Argus-T sling on incontinence rates, patient's quality of life and tape-related complications. Methods: Patients were eligible if persistent stress incontinence was present >= 12 months after radical prostatectomy. Measurements included 24 h frequency volume micturition list, 24 h pad test, 24 h pad count and quality of life questionnaires. Argus-T adjustable sling was placed with a single perineal route incision approach. Results: Seventy-eight patients were included, 69 +/- 6 years, pre-intervention 24 h urinary loss 212 (75-385) g. Directly after surgery, 63.6% of the patients was completely dry, 79.2% of the patients reported greater than 90% improvement of their urinary loss and 92.2% > 50% improvement. Median follow-up time was 3.2 (2.5-6.1) years. After 5 years of follow-up, 53.3% of the patients were completely dry, 71.5% reported an improvement greater than 90% and 79.6% reported an improvement of greater than 50%. Patients with preoperative urinary loss less than 250 g reported significantly higher improvement of their urinary loss compared to patients with urinary loss >= 250 g (p = .02). Patients satisfaction was still increased after 5 years follow-up (70 +/- 21 vs.16 +/- 9, p < .001) and patients quality of life remained high (85 +/- 20 vs. 88 +/- 13, p = .1). Complications were mainly observed directly after surgery. Two patients (2.6%) needed reimplantation of the sling. Conclusion: These data indicate that Argus-T sling is an effective treatment option in obtaining substantial long-term incontinence relief in patients with invalidating moderate stress urinary incontinence after radical prostatectomy

3-D Visualization and Inter-Session Comparison for Robotic Assisted Bladder Cancer Screening

Over 570,000 new cases of bladder cancer are diagnosed worldwide every year. It is essential to detect new tumors as early as possible to reduce the mortality rate. In addition, the muscle invasiveness of lesions should be quantified to determine the optimal treatment plan.Within the "Next-gen in-vivo cancer diagnostics" research project we propose a new cystoscopy instrument consisting of an optical coherence tomography (OCT) sensor, a camera and a light source, mounted on the tip of a concentric tube robot (CTR). The camera images could then be used to create 3-D reconstructions of the bladder wall and to quantifiy changes in its texture between successive cystoscopy sessions. In addition, the camera could guide the OCT sensor to investigate the bladder wall structure at the locations of possible tumors in order to investigate the malignancy and muscle invasiveness.This research specifically reports on creating 3-D reconstructions of bladder phantoms and co-registration of successive sessions, in order to automatically detect and indicate changes in texture which might be related to the onset and growth of tumors.The results show that cystoscopy images of the bladder could be reconstructed in 3-D and subsequently projected to a 2-D atlas. Registrations of successive sessions were effectively co-registered with help of the TPS algorithm and the system was able to automatically detect all six images of tumors which were added between the two sessions

Focal Salvage MR Imaging–Guided Cryoablation for Localized Prostate Cancer Recurrence after Radiotherapy:12-Month Follow-up

Purpose: To evaluate safety, quality of life (QoL), and local cancer control after focal salvage MR imaging–guided cryoablation in patients with local recurrence of prostate cancer (PCa) after radiotherapy. Materials and Methods: A retrospective, single-center study was performed in 62 patients with radiorecurrent PCa who underwent MR imaging–guided cryoablation since May 2011 with a follow-up ≥12 months in December 2017. Rates and descriptions of adverse events were reported. Ablation complications were classified according to the Clavien and SIR systems. Validated questionnaires were used to observe functional outcomes and QoL before therapy and 6 and 12 months after therapy. Cancer control was defined as no biochemical failure according to Phoenix criteria and no other clinical evidence for local or metastatic disease. Results: All procedures were technically feasible. The number of complications requiring major therapy (Clavien grade 3b/4 or SIR grade D/E/F) was low (2 [3.2%] and 1 [1.6%], respectively). After 12 months, the International Consultation of Incontinence Questionnaire–Short Form (P < .001) and 5-item International Index of Erectile Function (P = .001) scores became significantly worse, indicating increased symptoms of incontinence and diminished erectile function, without compromising QoL. Six patients developed metastases within 6 months. After 12 months, 36 patients (63%) were disease-free. Conclusions: Focal salvage MR imaging–guided cryoablation is safe and is associated with a high technical success rate, preservation of QoL, and local PCa control. This treatment can be a reasonable alternative to salvage radical prostatectomy in properly selected patients with low morbidity and preservation of QoL; however, longer follow-up is needed

The effect of office based flexible and rigid cystoscopy on pain experience in female patients

Purpose: Rigid and flexible cystoscopies are both routinely used in female patients. Literature is conflicting whether flexible cystoscopy is less painful compared to rigid cystoscopy. The aim of this study was therefore to investigate whether using flexible cystoscopy leads to less discomfort and pain compared to rigid cystoscopy in female patients who underwent first time cystoscopy. Materials and Methods: One hundred eighty-nine female patients, who never had undergone cystoscopy, were randomized into 2 groups: 92 patients underwent rigid cystoscopy and 97 patients flexible cystoscopy. Directly after the cystoscopy procedure all patients were asked to fill out their pain experience on a 100-mm visual analogue pain scale (VAS). Results: Median VAS score was significantly lower for women undergoing flexible cystoscopy (0 [0–20]) compared to rigid cystoscopy (15 [0–38], p<0.001). In addition, age was inversely associated with VAS score, indicating that younger females experienced more pain (R=−0.30, p=0.001). The use of flexible cystoscopy was associated with a decrease in VAS score and remained significant after adjustment for age, sex of urologist, performing urologist and indication (standardized β =−0.17, p=0.048). Conclusions: The use of flexible cystoscopy resulted in a significantly lower pain experience compared to rigid cystoscopy. Based on patient’s pain experience during cystoscopy, this study implicates to use flexible cystoscopy in female patients who undergo first time cystoscopy

Two-year follow-up of the phase II marker lesion study of intravesical apaziquone for patients with non-muscle invasive bladder cancer

Item does not contain fulltextOBJECTIVES: To study the time-to-recurrence and duration of response in non-muscle invasive bladder cancer (NMIBC) patients, with a complete ablative response after intravesical apaziquone instillations. METHODS: Transurethral resection of bladder tumour(s) (TURBT) was performed in patients with multiple pTa-T1 G1-2 urothelial cell carcinoma (UCC) of the bladder, with the exception of one marker lesion of 0.5-1.0 cm. Intravesical apaziquone was administered at weekly intervals for six consecutive weeks, without maintenance instillations. A histological confirmed response was obtained 2-4 weeks after the last instillation. Routine follow-up (FU) was carried out at 6, 9, 12, 18 and 24 months from the first apaziquone instillation. RESULTS: At 3 months FU 31 of 46 patients (67.4%) had a complete response (CR) to ablative treatment. Side-effects on the long-term were only mild. Two CR patients dropped out during FU. On intention-to-treat (ITT) analysis 49.5% of the CR patients were recurrence-free at 24 months FU, with a median duration of response of 18 months. Of 15 no response (NR) patients, only two received additional prophylactic instillations after TURBT. On ITT-analysis 26.7% of the NR patients were recurrence-free (log rank test, P = 0.155). The overall recurrence-free survival was 39% (18 of 46 patients) at 24 months FU. CONCLUSIONS: The CR of the marker lesion in 67% of patients was followed by a recurrence-free rate of 56.5% at 1-year FU, and 49.5% at 2-year FU. These long-term results are good in comparison with the results of other ablative studies

High Diagnostic Performance of Short Magnetic Resonance Imaging Protocols for Prostate Cancer Detection in Biopsy-naive Men: The Next Step in Magnetic Resonance Imaging Accessibility

Background: To make magnetic resonance imaging (MRI) more accessible to men at risk of high-grade prostate cancer (PCa), there is a need for quicker, simpler, and less costly MRI protocols. Objective: To compare the diagnostic performance of monoplanar (“fast” biparametric MRI [bp-MRI]) and triplanar noncontrast bp-MRI with that of the current contrast-enhanced multiparametric MRI (mp-MRI) in the detection of high-grade PCa in biopsy-naïve men. Design, setting, and participants: A prospective, multireader, head-to-head study included 626 biopsy-naïve men, between February 2015 and February 2018. Intervention: Men underwent prebiopsy contrast-enhanced mp-MRI. Prior to biopsy, two blinded expert readers subsequently assessed “fast” bp-MRI, bp-MRI, and mp-MRI. Thereafter, systematic transrectal ultrasound-guided biopsies (SBs) were performed. Men with suspicious mp-MRI (Prostate Imaging Reporting and Data System 3–5 lesions) also underwent MR-in-bore biopsy (MRGB). Outcome measurements and statistical analysis: Primary outcome was the diagnostic performance of each protocol for the detection of high-grade PCa. Secondary outcomes included the difference in biopsy avoidance, detection of low-grade PCa, acquisition times, decision curve analyses, inter-reader agreement, and direct costs. Results from combined MRGB and SB were used as the reference standard. High-grade PCa was defined as grade 2. Results and limitations: Sensitivity for high-grade PCa for all protocols was 95% (180/ 190; 95% confidence interval [CI]: 91–97%). Specificity was 65% (285/436; 95% CI: 61–70%) for “fast” bp-MRI and 69% (299/436; 95% CI: 64–73%) for bp-MRI and mp-MRI. With fast bp-MRI, 0.96% (6/626) more low-grade PCa was detected. Biopsy could be avoided in 47% for the fast bp-MRI and in 49% for the bp-MRI and mp-MRI protocols. Fast bp-MRI and bp-MRI can be performed in 8 and 13 min, respectively, instead of 16

Short-term Changes in Health-related Quality of Life of Patients Undergoing Radical Surgery for Upper Urinary Tract Urothelial Carcinoma: Results from a Prospective Phase 2 Clinical Trial

Background and objective: The possible negative impact of radical surgery on patients’ health-related quality of life (HRQoL) plays an important role in preoperative counseling. Here, we analyzed the HRQoL of patients treated for upper urinary tract urothelial carcinoma (UTUC) in the context of a single-arm phase 2 multicenter study, in which the safety and efficacy of a single preoperative intravesical instillation with mitomycin C were investigated. Our objective was to investigate early changes in HRQoL in patients undergoing radical surgery for UTUC and identify factors associated with these outcomes. Methods: Patients with pTanyN0-1M0 UTUC were prospectively included. HRQoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) questionnaire at baseline, and at 1 and 3 mo after surgery. A linear mixed model was used to evaluate the changes in HRQoL over time and identify the variables associated with these outcomes. The clinical effect size was used to assess the clinical impact and level of perceptibility of HRQoL changes for clinicians and/or patients based on given thresholds. Key findings and limitations: Between 2017 and 2020, 186 patients were included. At baseline, 1 mo after surgery, and 3 mo after surgery, response rates were 91%, 84%, and 78%, respectively. One month after surgery, a statistically significant and clinically relevant deterioration was observed in physical, role, and social functioning, and for the included symptom scales: constipation, fatigue, and pain. An improvement in emotional functioning was observed. At 3 mo, HRQoL returned to baseline levels, except emotional functioning, which improved at 1 mo and persisted to be better than that before surgery. Age >70 yr was associated with worse physical functioning, but better social and emotional functioning. Male patients reported better emotional functioning than females. Postoperative complications were negatively associated with social functioning. Conclusions and clinical implications: UTUC patients treated with radical surgery experienced a significant, albeit temporary, decline in HRQoL. Three months following surgery, HRQoL outcomes returned to baseline levels. This information can be used to counsel UTUC patients before undergoing radical surgery and contextualize recovery after surgery. Patient summary: We investigated the changes in quality of life as reported by patients who underwent surgery for upper tract urothelial carcinoma (UTUC). We found that patients experienced a decline in quality of life 1 mo after surgery, but this was temporary, with full recovery of quality of life 3 mo after surgery. These findings can help doctors and other medical staff in counseling UTUC patients before undergoing radical surgery
