Abstract

Objective

To evaluate the efficacy of a novel and selective β3‐adrenoreceptor agonist vibegron on urgency urinary incontinence (UUI) in patients with overactive bladder (OAB). Follow us visaliaweddingstyle for more details .

Patients and Methods

post hoc analysis was performed in patients with UUI (>0 episodes/day) who were assigned to receive vibegron or placebo in a vibegron phase 3 study. Patients were subclassified into mild/moderate (>0 to <3 UUI episodes/day) or severe UUI (≥3 UUI episodes/day) subgroup. Changes from baseline in number of UUI episodes/day, in number of urgency episodes/day, and in voided volume/micturition were compared between the groups. The percentage of patients who became UUI‐free (‘diary‐dry’ rate) and the response rate (percentage of patients with scores 1 [feeling much better] or 2 [feeling better] assessed by the Patient Global Impression scale [PGI]) were evaluated.

Results

Changes in numbers of UUI episodes at week 12 in the vibegron 50 mg, vibegron 100 mg and placebo groups, respectively, were −1.35, −1.47 and −1.08 in all patients, −1.04, −1.13 and −0.89 in the mild/moderate UUI subgroup, and −2.95, −3.28 and −2.10 in the severe UUI subgroup. The changes were significant in the vibegron 50 and 100 mg groups vs placebo regardless of symptom severity. Change in number of urgency episodes/day was significant in the vibegron 100 mg group vs placebo in all patients and in both severity subgroups. In the vibegron 50 mg group, a significant change vs placebo was observed in all patients and in the mild/moderate UUI subgroup. Change in voided volume/micturition was significantly greater in the vibegron 50 and 100 mg groups vs placebo in all patients, as well as in the both severity subgroups. Diary‐dry rates in the vibegron 50 and 100 mg groups were significantly greater vs placebo in all patients and in the mild/moderate UUI subgroup. In the severe UUI subgroup, however, a significant difference was observed only in the vibegron 50 mg group. Response rates assessed by the PGI were significantly higher in the vibegron groups vs placebo in all patients and in the both severity subgroups. Vibegron administration, OAB duration ≤37 months, mean number of micturitions/day at baseline <12.0 and mean number of UUI episodes/day at baseline <3.0 were identified as factors significantly associated with normalization of UUI.

Conclusions

Vibegron, a novel β3‐adrenoreceptor agonist, significantly reduced the number of UUI episodes/day and significantly increased the voided volume/micturition in patients with OAB including those with severe UUI, with the response rate exceeding 50%. These results suggest that vibegron can be an effective therapeutic option for OAB patients with UUI.

The ProtecT trial: analysis of the patient cohort, baseline risk stratification and disease progression

Read the full article

Abstract

Objective

To test the hypothesis that the baseline clinico‐pathological features of the men with localized prostate cancer (PCa) included in the ProtecT (Prostate Testing for Cancer and Treatment) trial who progressed (n = 198) at a 10‐year median follow‐up were different from those of men with stable disease (n = 1409).

Patients and Methods

We stratified the study participants at baseline according to risk of progression using clinical disease stage, pathological grade and PSA level, using Cox proportional hazard models.

Results

The findings showed that 34% of participants (n = 505) had intermediate‐ or high‐risk PCa, and 66% (n = 973) had low‐risk PCa. Of 198 participants who progressed, 101 (51%) had baseline International Society of Urological Pathology Grade Group 1, 59 (30%) Grade Group 2, and 38 (19%) Grade Group 3 PCa, compared with 79%, 17% and 5%, respectively, for 1409 participants without progression (P < 0.001). In participants with progression, 38% and 62% had baseline low‐ and intermediate‐/high‐risk disease, compared with 69% and 31% of participants with stable disease (P < 0.001). Treatment received, age (65–69 vs 50–64 years), PSA level, Grade Group, clinical stage, risk group, number of positive cores, tumour length and perineural invasion were associated with time to progression (P ≤ 0.005). Men progressing after surgery (n = 19) were more likely to have a higher Grade Group and pathological stage at surgery, larger tumours, lymph node involvement and positive margins.

Conclusions

We demonstrate that one‐third of the ProtecT cohort consists of people with intermediate‐/high‐risk disease, and the outcomes data at an average of 10 years’ follow‐up are generalizable beyond men with low‐risk PCa.

Abstract

Since robot‐assisted radical prostatectomy (RARP) started to be regularly performed in 2001, the procedure has typically followed the original retropubic approach, with incremental technical improvements in an attempt to improve outcomes. These include the running Van‐Velthoven anastomosis, posterior reconstruction or ‘Rocco stitch’, and cold ligation of the Santorini plexus/dorsal vein to maximise urethral length. In 2010, Bocciardi’s team in Milan proposed a novel posterior or ‘Retzius‐sparing’ RARP (RS‐RARP), mirroring the classic open perineal approach. This allows avoidance of supporting structures, such as the puboprostatic ligaments, endopelvic fascia, and Santorini plexus, preserving the normal anatomy as much as possible and limiting damage that may contribute to improved postoperative continence and erectile function. There has been much heralding of the excellent functional outcomes in both the medical and the lay press, but as yet no focus or real mention of any potential downsides of this new technique.

Residents’ podcast: Cluster analysis of multiple chronic conditions associated with urinary incontinence among women in the USA

Giulia Lane M.D. and Iryna Crescenze M.D. are Fellows in Neuro-urology and Pelvic Reconstruction in the Department of Urology at the University of Michigan.

In this podcast they discuss the following BJUI Article of the Week:

Cluster analysis of multiple chronic conditions associated with urinary incontinence among women in the USA

Abstract

Objective

To identify patterns of prevalent chronic medical conditions among women with urinary incontinence (UI).

Materials and Methods

We combined cross‐sectional data from the 2005–2006 to 2011–2012 US National Health and Nutrition Examination Surveys, and identified 3 800 women with UI and data on 12 chronic conditions. Types of UI included stress UI (SUI), urgency UI (UUI), and mixed stress and urgency UI (MUI). We categorized UI as mild, moderate or severe using validated measures. We performed a two‐step cluster analysis to identify patterns between clusters for UI type and severity. We explored associations between clusters by UI subtype and severity, controlling for age, education, race/ethnicity, parity, hysterectomy status and adiposity in weighted regression analyses.

Results

Eleven percent of women with UI had no chronic conditions. Among women with UI who had at least one additional condition, four distinct clusters were identified: (i) cardiovascular disease (CVD) risk‐younger; (ii) asthma‐predominant; (iii) CVD risk‐older; and (iv) multiple chronic conditions (MCC). In comparison to women with UI and no chronic diseases, women in the CVD risk‐younger (age 46.7 ± 15.8 years) cluster reported the highest rate of SUI and mild UI severity. In the asthma‐predominant cluster (age 51.5 ± 10.2 years), women had more SUI and MUI and more moderate UI severity. Women in the CVD risk‐older cluster (age 57.9 ± 13.4 years) had the highest rate of UUI, along with more severe UI. Women in the MCC cluster (age 61.0 ± 14.8 years) had the highest rates of MUI and the highest rate of moderate/severe UI.

Conclusions

Women with UI rarely have no additional chronic conditions. Four patterns of chronic conditions emerged with differences by UI type and severity. Identification of women with mild UI and modifiable conditions may inform future prevention efforts.

Abstract

Objective

To assess the chronological changes in urinary incontinence and urethral function before and after radical prostatectomy (RP), and to compare the findings of pelvic magnetic resonance imaging (MRI) before and after RP to evaluate the anatomical changes.

Patients and Methods

In total, 185 patients were evaluated with regard to the position of the distal end of the membranous urethra (DMU) on a mid‐sagittal MRI slice and urethral sphincter function using the urethral pressure profilometry. The patients also underwent an abdominal leak point pressure test before RP and at 10 days and 12 months after RP. The results were then compared with the chronological changes in urinary incontinence.

Results

The MRI results showed that the DMU shifted proximally to an average distance of 4 mm at 10 days after RP and returned to the preoperative position at 12 months after RP. Urethral sphincter function also worsened 10 days after RP, with recovery after 12 months. The residual length of the urethral stump and urinary incontinence were significantly associated with the migration length of the DMU at 10 days after RP. The residual length of the urethral stump was a significant predictor of urinary incontinence after RP.

Conclusion

This is the first study to elucidate that the slight vertical repositioning of the membranous urethra after RP causes chronological changes in urinary incontinence. A long urethral residual stump reduces urinary incontinence after RP.
