The Long-Term Effect of Radical Prostatectomy on Erectile Function, Urinary Continence, and Lower Urinary Tract Symptoms: A Comparison to Age-Matched Healthy Controls

Specific nursing improves postoperative urine control function and the self-efficacy of patients undergoing radical prostatectomies

BACKGROUND

Radical prostatectomy is a treatment for prostate cancer (PC), but most patients suffer urinary incontinence, decreased urinary control function, and poor prognoses after the surgery. Specific nursing intervention is a nursing model based on the patients' individual conditions and disease progression.

OBJECTIVE

To investigate the effects of specific nursing intervention on the urinary control functions and self-efficacy of radical prostatectomy patients.

METHODS

From April 1, 2016 to June 30, 2019, 149 patients who underwent radical prostatectomies in our hospital were retrospectively selected for this observational study and assigned to two groups in accordance with the different nursing intervention method each patient underwent. Seventy-six patients who underwent specific nursing intervention were included in the observation group (OG), and 73 patients who underwent routine nursing intervention were included in the control group (CG). The clinical symptoms, the urodynamic indexes, the recoveries of urinary control function, the incidences of urinary incontinence, and the complications were observed in both groups. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores were used to evaluate the unhealthy emotions. The self-efficacy scale (GSES) and SF-36 were used to evaluate the self-efficacy and the quality of life (QOL), respectively.

RESULTS

After the nursing, the improvement in the clinical symptoms in the OG was significantly better than it was in CG. The improvement in the postoperative urodynamic indexes in the OG was significantly better than it was in the CG. The recovery of urinary control function in the OG was significantly higher than it was in the CG. The incidence of urinary incontinence in OG was significantly lower than it was in the CG. The incidence of complications in the OG was significantly lower than it was in the CG. The SAS and SDS scores in the OG were significantly lower than they were in the CG. After the intervention, the patients' GSES and SF-36 scores in the OG were significantly higher than they were in the CG.

CONCLUSION

Specific nursing intervention can ameliorate the urinary control functions and self-efficacy, reduce unhealthy emotions, and improve the QOL of radical prostatectomy patients.

The Effectiveness of Pelvic Floor Muscle Training in Men after Radical Prostatectomy Measured with the Insert Test

A commonly used physiotherapeutic method for the treatment of urinary incontinence (UI) after radical prostatectomy (RP) is pelvic floor muscle training (PFMT). The aim of this study was to evaluate the effectiveness of PFMT by enhanced biofeedback using the 1h pad-weighing test. The following factors were taken into consideration in the analysis of PFMT effectiveness: the relevance of the patients’ age, time from RP, BMI, mental health, functional state, and depression. A total of 60 post-RP patients who underwent 10-week PFMT were studied. They were divided into groups: A (n = 20) and B (n = 20) (random division, time from RP: 2−6 weeks) and group C (time from RP > 6 weeks). Group B had enhanced training using EMG biofeedback. UI improved in all groups: A, p = 0.0000; B, p = 0.0000; and C, p = 0.0001. After the completion of PFMT, complete control over miction was achieved by 60% of the patients in group A, 85% in group B, and 45% in group C. There was no correlation between the results of PFMT efficacy and patients’ age, BMI, time from RP, mental health, functional state, and depression. PFMT is highly effective in UI treatment. The enhancement of PFMT by EMG biofeedback seems to increase the effectiveness of the therapy.

Complete study for erectile dysfunction (CompED) improving diagnosis and treatment decision-making

Erectile dysfunction is a condition associated with increasing age. Patient evaluation and management should follow a comprehensive, stepwise approach. The aim of this article was to report our experience with the complete study for erectile dysfunction, including intracavernous injection rigidity test, biothesiometry and colour duplex Doppler ultrasound. Data were collected and analysed prospectively. The primary end point was to determine whether treatment decision-making was eased by the CompED test. Secondary end points were to establish which clinical variables prior to the study could impact the results of the CompED test, to finally improve patient selection for the study. 187 patients were recruited, 31.2% of the patients had an axial rigidity below 50%, 28.5% had a peak systolic velocity <25 cm/s, 13.2% had an end-diastolic velocity >5cm/s and 27.5% had an abnormal biothesiometry. The factors that best predicted an abnormal result in any of the tests were age >70 years, IIEF domain A < 14 points, and previous radical prostatectomy or radiotherapy. The CompED test stands as a new alternative for the evaluation of patients with erectile dysfunction, being less time consuming, aiding in a more accurate determination of the aetiology and guiding treatment decision-making.

Change of preoperative symptoms of the late-onset hypogonadism syndrome after robot-assisted radical prostatectomy

Background:

As prostate cancer (PCa) is a common cancer among older men, patients with PCa often show aging male symptoms (AMSs). This study aimed to investigate the preoperative AMSs of the late-onset hypogonadism (LOH) syndrome and the effects on them after robot-assisted radical prostatectomy (RARP).

Materials and methods:

One hundred eighty-eight patients who underwent RARP without androgen deprivation therapy were measured for serum free and serum total testosterone, and were preoperatively assessed for symptoms of the LOH syndrome using a questionnaire containing an AMS score. Patients with a preoperative AMS score higher than 37 and a serum free testosterone level lower than 8.5 pg/mL were classified as Group A, with the remaining classified as Group B. AMS scores were measured at 1, 3, 6, 9, and 12 months after surgery.

Results:

Of the 188 patients, 49 and 139 patients were classified as Groups A and B, respectively. Preoperative AMS scores were 44.5 ± 8.2 in Group A and 28.6 ± 5.3 in Group B (p < 0.0001). AMS scores in Group A significantly improved 1 month after RARP (30.6 ± 8.4, p < 0.0001) compared with their preoperative scores and remained at the same level from 3 to 12 months postoperatively, whereas those in Group B became significantly worse (32.0 ± 7.8, p < 0.0001) than their preoperative ones. There were no differences between AMS scores in Groups A and B at every postoperative period (p = 0.3259, 0.2730, 0.2429, 0.4629, 0.1771 at 1, 3, 6, 9, and 12 months after surgery, respectively).

Conclusions:

Our results indicate that AMSs in PCa patients with the LOH syndrome can expect the same level of improvement as patients without it.

A novel tool to predict functional outcomes after robot-assisted radical prostatectomy and the value of additional surgery for incontinence

OBJECTIVES

To develop and validate a model to predict 12-month continence status after robot-assisted radical prostatectomy (RARP) from preoperative and 3-month postoperative data; this model could help in informing patients on their individualised risk of urinary incontinence (UI) after RP in order to choose the best treatment option.

PATIENTS AND METHODS

Data on 9421 patients in 25 Belgian centres were prospectively collected (2009-2016) in a compulsory regional database. The primary outcome was the prediction of continence status, using the International Consultation on Incontinence Urinary Incontinence Short Form (ICIQ-UI-SF) at 12-months after RARP. Linear regression shrinkage was used to assess the association between preoperative 3-month postoperative characteristics and 12-month continence status. This association was visualised using nomograms and an online tool.

RESULTS

At 12 months, the mean (sd) score of the ICIQ-UI-SF questionnaire was 4.3 (4.7), threefold higher than the mean preoperative score of 1.4. For the preoperative model, high European Association of Urology risk classification for biochemical recurrence (estimate [Est.] 0.606, se 0.165), postoperative radiotherapy (Est. 1.563, se 0.641), lower preoperative European Organisation for Research and Treatment of Cancer quality of life questionnaire 30-item core (EORCT QLQ-C30)/quality of life (QoL) score (Est. -0.011, se 0.003), higher preoperative ICIQ-UI-SF score (Est 0.214, se 0.018), and older age (Est. 0.058, se 0.009), were associated with a higher 12-month ICIQ-UI-SF score. For the 3-month model, higher preoperative ICIQ-UI-SF score (Est. 0.083, se 0.014), older age (Est. 0.024, se 0.007), lower 3-month EORCT QLQ-C30/QoL score (Est. -0.010, se 0.002) and higher 3-month ICIQ-UI-SF score (Est. 0.562, se 0.009) were associated with a higher 12-month ICIQ-UI-SF score.

CONCLUSIONS

Our models set the stage for a more accurate counselling of patients. In particular, our preoperative model assesses the risk of UI according to preoperative and early postoperative variables. Our postoperative model can identify patients who most likely would not benefit from conservative treatment and should be counselled on continence surgery.

Pelvic Floor Muscle Training in Radical Prostatectomy and Recent Understanding of the Male Continence Mechanism: A Review

OBJECTIVE

Pelvic floor muscle training (PFMT) is recommended as part of supportive care for patients with prostate cancer. It can assist in reducing treatment-related symptoms such as urinary incontinence. This literature review aims to discuss recent innovative findings on the pathophysiology of the male continence mechanism and implications for PFMT in radical prostatectomy.

DATA SOURCES

CINAHL, Embase, Web of Science, Emcare and PsycINFO were searched until January 2020.

CONCLUSION

Nurses providing supportive care for patients undergoing radical prostatectomy can engage in-clinic in the instruction and recommendation of pre- and postoperative PFMT and delivering guidance on home-based programs to promote motor learning.

IMPLICATIONS FOR NURSING PRACTICE

Optimal postoperative urinary incontinence outcomes are suggested to be promoted by preoperative PFMT. Training focused on the urethral and anterior pelvic floor muscle complex has been shown to facilitate mid urethral occlusion required for continence. Prescription of PFMT should be individualised, focusing on skill acquisition and motor learning, which is in line with recent knowledge developments in male pelvic floor anatomy.

Pelvic floor muscle training in radical prostatectomy: a randomized controlled trial of the impacts on pelvic floor muscle function and urinary incontinence

BACKGROUND

Pelvic floor muscle training (PFM) training for post-prostatectomy incontinence (PPI) is an important rehabilitative approach, but the evidence base is still evolving. We developed a novel PFM training program focussed on activating fast and slow twitch muscle fibres. We hypothesized that this training, which commenced pre-operatively, would improve PFM function and reduce PPI, when compared to a control group.

METHODS

This randomized trial allocated 97 men (63 ± 7y, BMI = 25.4, Gleason 7) undergoing radical prostatectomy (RP) to either a control group (n = 47) performing low-volume rehabilitation, or an intervention group (n = 50). Both interventions commenced 5 weeks prior to surgery and continued for 12 weeks post-RP. Participants were assessed pre-operatively and at 2, 6 and 12 weeks post-RP using 24 h pad weights, International Prostate Symptom Score (IPSS), Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) and real time ultrasound (RTUS) measurements of PFM function.

RESULTS

Following RP, participants in the control group demonstrated a slower return to continence and experienced significantly more leakage (p < 0.05), measured by 24 h pad weight, compared to the intervention group, suggesting an impact of the prehabilitation protocol. PFM function measures were enhanced following RP in the intervention group. Secondary measures (IPSS, EPIC-CP and RTUS PFM function tests) demonstrated improvement across all time points, with the intervention group displaying consistently lower "bothersome" scores.

CONCLUSIONS

A pelvic floor muscle exercise program commenced prior to prostate surgery enhanced post-surgical measures of pelvic floor muscle function, reduced PPI and improved QoL outcomes related to incontinence.

TRIAL REGISTRATION

The trial was registered in the Australia New Zealand Clinical Trials Registry and allocated as ACTRN12617001400358. The trial was registered on 4/10/2017 and this was a retrospective registration.

Penile Rehabilitation: The "Up"-date

Purpose of Review

The purpose of this review is to review the penile rehabilitation literature published since the beginning of 2017. Specific emphasis was placed on determining how the new findings increase our understanding of the mechanisms leading to recovery of erectile function after pelvic surgery and to identify potential focus areas for future studies.

Recent Findings

A meta-analysis of penile rehabilitation after prostatectomy was published in early 2017 reporting that PDE-5 inhibitors, intracavernosal injection (ICI) therapy and vacuum erection devices (VED) improved erectile function; however, the benefit was not observed after a washout period. Preclinical studies have identified potential regenerative therapies after cavernous nerve injury.

Summary

While significant methodological challenges remain, recent literature suggests benefits to starting penile rehabilitation immediately after surgery, but not extending past 1 year post-operatively. The cost-benefit ratio of penile rehabilitation remains unclear; however, decreasing costs of PDE-5 inhibitors as well as improvements in characterizing post-surgical erectile dysfunction may help to personalize penile rehabilitation, improve outcomes and improve the cost-benefit ratio. Better and more consistent trial design is needed to develop the optimal regimen(s) for restoring sexual function in men. Finally, future studies to translate promising preclinical regeneration therapies to humans are also needed.

Effects of Biofeedback in Preventing Urinary Incontinence and Erectile Dysfunction after Radical Prostatectomy

In this study, we present a biofeedback method for the strengthening of perineal muscles during the preoperative procedures for radical prostatectomy, and we evaluate this technique as a prevention measure against complications such as urinary incontinence (UI) and erectile dysfunction (ED), which affect prostatectomy patients after surgery. In the experimental protocol, the patients performed specific exercises with the help of a device that provided the patient with visual biofeedback, based on a plot of the anal pressure. For the experimental protocol, we selected 20 male patients, with an average age of 64.0 years, and submitted them to ten therapeutic sessions each. A control group consisting of 32 men with an average age of 66.3 years, who were treated with the same surgical procedure but not with the preoperative procedures, also took part in the experiment. To evaluate UI and ED after the surgery in both control and experimental groups, we used two validated questionnaires-to assess UI, we used the King's Health Questionnaire (KHQ) and, for ED, we used the International Index of Erectile Function (IIEF-5) Questionnaire. We compared the variables associated with UI and ED after the surgery for the control and experimental groups. The occurrence of UI after radical prostatectomy in the control group (100% of the patients) was higher than that for the experimental group (5% of the patients), with p < 0.0001. Likewise, the occurrence of erectile dysfunction after prostatectomy in the control group (48.6% of the patients) was higher than that for the experimental group (5% of the patients), with p < 0.0001. The number of nocturia events also decreased as a consequence of the intervention (p < 0.0001), as did the number of disposable underwear units for urinary incontinence (p < 0.0001). Furthermore, we compared, only for the experimental group, the anal pressure before the biofeedback intervention and after the surgery, and we verified that the anal pressure after surgery was significantly higher (p < 0.0001). The results strongly suggest that the preoperative biofeedback procedure was effective in decreasing urinary incontinence and erectile dysfunction after radical prostatectomy. As future work, we intend to extend this analysis for larger samples and considering a broader age range.
