The preoperative pad test as a predictor of urinary incontinence and quality of life after robot-assisted radical prostatectomy: a prospective, observational, clinical study

Patients experience with the use of a penile clamp in post-prostatectomy incontinence - a prospective pilot study

OBJECTIVES

The aim of this study was to assess the efficacy of a penile clamp in managing urinary incontinence (UI) and its impact on perceived quality of life (QoL) amongst post-prostatectomy patients.

MATERIAL AND METHODS

A prospective pilot study was conducted including patients with post-prostatectomy UI treated with a penile clamp. Inclusion criteria consisted of UI after radical prostatectomy, good hand function, full cognitive function and a minimum penile length of 3 cm and a circumference of 5 cm. An appropriately sized penile clamp was selected during the first visit, and patients were given instructions on how to use it. The first follow-up was a scheduled phone call 1 week after the initial visit. Formal evaluations were performed prior to use of the penile clamp and again after 3 months of usage. These consisted of weighing pads during the daytime with evaluation of leakage, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), incontinence-QoL (I-QoL) and a questionnaire specific for the penile clamp.

RESULTS

There were 22 patients included, and two were excluded due to reduced hand function and surgery before the study endpoint. The results showed a significant median reduction of urinary leakage of 57% at rest and 58% during physical activity. One complication was observed, as one patient developed a pinching ulcer, after extensive usage. ICIQ-SF showed an increase of 6% for the included patients (n = 20). Ten patients were satisfied with the clamp, and 15 would recommend the clamp to others.

CONCLUSION

The penile clamp shows promising results in reducing leakage with minimal risks of complications. It can be used as a treatment for patients awaiting surgery. However, patient selection is important regarding hand function, cognitive function and the penile anatomy.

Urinary Symptoms Change and Quality of Life After Robotic Radical Prostatectomy: A Secondary Analysis of a Randomized Controlled Trial

OBJECTIVE

To present the patient-reported quality of life (QoL) outcomes from a prospective, randomized controlled trial comparing the use of pelvic floor muscle training (PFMT) and duloxetine after robot-assisted radical prostatectomy (RARP).

METHODS

We identified 213 men with organ-confined disease having post-RARP urinary incontinence who were randomly assigned to received PFMT, duloxetine, combined PFMT-duloxetine and pelvic floor muscle home exercises. Urinary symptoms burden was measured by marked clinical important difference improvement (MCID) defined by using the International Prostate Symptom Score (IPSS) difference of - 8 points (ΔIPSS ≤-8). QoL was assessed according to Visual Analog Scale (VAS), King's Health Questionnaire (KQH), and International Index of Erectile Function (IIEF-5). Multivariable regression analyses aimed to predict MCID, burden of urinary symptoms (IPSS ≥8), and patients reporting to be satisfied (IPSS QoL ≤2) or comfortable (VAS ≤1) post-RARP.

RESULTS

Moderate to severe urinary symptoms decreased from 48% preoperatively to 40%, 34%, and 23% at 3, 6, and 12months post-RARP. After surgery, MCID improvement was observed in 19% of patients, and deterioration in 3.3%. Large prostate was the only factor associated to MCID (OR 1.03 [95%CI 1.01-1.05], P = .005). At 6months, patients reached the same degree of preoperative satisfaction. Neurovascular bundle preservation was the only predictor of being comfortable regarding urinary symptoms postoperatively (OR 12.8 [CI95% 1.47-111.7], P = .02 at 3months) and was also associated to higher median postoperative IIEF-5.

CONCLUSION

Despite urinary incontinence following RARP, patients with larger prostates experience a reduction of lower urinary tract symptoms within a year, which subsequently elevates QoL. Furthermore, nerve-sparing surgery augments erectile function and urinary outcomes, shaping postoperative QoL.

Effect of different postures of Pilates combined with Kegel training on pelvic floor muscle strength in post-prostatectomy incontinence

PURPOSE

Urinary incontinence seriously affects the daily ability of older males. This study compared the effect of different postures of Pilates combined with Kegel training on pelvic floor muscle strength in post-prostatectomy incontinence.

METHODS

We included 38 valid samples [group A = 13 (less than 3 months after surgery), group B = 15 (4-6 months after surgery), group C = 10 (more than 6 months after surgery)] and surface electromyography (EMG) was used to record the maximum, and root mean square values of participants in the three groups under four postures.

RESULTS

There were significant differences in the maximum and mean values among the three groups. In group A, the mean values were 13.04 ± 1.56, 16.98 ± 1.76, 41.58 ± 4.17, and 24.53 ± 2.45 (P < 0.01), respectively. In group B, the mean values were 13.85 ± 1.55, 18.63 ± 1.44, 45.87 ± 3.31, and 28.63 ± 2.02 (P < 0.01), respectively. In group C, the mean values were 14.80 ± 1.32, 19.59 ± 1.55, 47.85 ± 5.05, and 30.11 ± 2.26 (P < 0.01), respectively. The mean and peak values of surface EMG in the three groups correlated with the four basic movements. R² values were 0.76 and 0.85, 0.77 and 0.88, 0.77 and 0.91, respectively.

CONCLUSIONS

Pilates with Kegel training was superior to Kegel training alone in unit recruitment ability of the pelvic floor muscles. Pilates training in different positions is recommended according to the patient's condition.

The association between the parameters of uroflowmetry and lower urinary tract symptoms in prostate cancer patients after robot-assisted radical prostatectomy

OBJECTIVE

To investigate changes in uroflowmetry parameters in men undergoing robot-assisted radical prostatectomy (RARP) for prostate cancer.

MATERIALS AND METHODS

Four hundred and twenty-eight patients received uroflowmetry testing before and after RARP from November 2011 to December 2018. Clinicopathological data, including age, initial prostate-specific antigen (PSA), prostate volume, clinical stage, body mass index (BMI), uroflowmetry parameters, and core lower urinary tract symptom scores (CLSS) were retrospectively obtained from clinical records. Changes in uroflowmetry parameters were analyzed for statistical predictors and effects on post-operative outcomes.

RESULTS

A significant increase in maximum flow rate (MFR) and decreases in voided volume (VV) and post-void residual urine (PVR) were seen. In multivariate analysis, age was a negative predictor of MFR increase, while prostate volume was a positive predictor of PVR decrease and MFR increase. VV decrease led to worse incontinence symptoms, while PVR decrease and MFR increase led to improvement in voiding symptoms such as slow stream and straining. Continence recovery curves showed that VV decrease were associated with a delay in continence recovery.

CONCLUSIONS

Significant changes were seen in uroflowmetry results after RARP, each parameter directly related to urinary symptoms. In particular, VV decrease was associated with a worsening of incontinence symptoms and continence recovery.

Multiple Endoclip Retraction Technique (MERT) in Laparoscopic Burch

Background and Objectives:

The multiple endoclip retraction technique (MERT) was developed based on our experience with suturing renal parenchyma in laparoscopic partial nephrectomy. In this study we prospectively evaluated the one-year results of cases treated by transperitoneal laparoscopic Burch with the MERT.

Methods:

The patients were evaluated with stress test, one-hour pad test, and were requested to complete the International Continence Society Incontinence Questionnaire short form (ICIQ-SF) in the postoperative period. The follow-up periods were postoperative 3, 6, and 12 months.

Results:

The primary outcome of this study was surgical success, defined as being cured of stress urinary incontinence (SUI) (no symptoms), experiencing improved symptoms of SUI in ICIQ-SF and negative stress test, and less than 2g urine leakage in a one-hour pad test.

No statistically significant difference was found in terms of age, number of children, and body mass index (BMI) in patients according to the results of the 12 month postoperative stress test. We found statistically significant improvements at all control months in terms of stress test and pad weight. ICIQ-SF results showed a significant decrease at three months in patients who recovered after the operation. This rate has not changed in following control months. However, there was no statistical change in ICIQ-SF values in patients who did not recover after the operation.

Conclusion:

MERT seems to be one of the safe and effective modifications in the management of SUI with good one year outcomes when performed by suitably trained experienced surgeons.

Impacts of Neoadjuvant Hormonal Therapy Prior to Robot-Assisted Radical Prostatectomy on Postoperative Hormonal- and Sexual-Related Quality of Life – Assessment by Patient-Reported Questionnaire

Purpose

Neoadjuvant hormonal therapy (HT) before radical prostatectomy (RP) is not recommended by current guidelines in terms of oncological outcomes. Despite this, neoadjuvant HT is sometimes conducted before RP for a small proportion of patients in clinical practice. This study evaluated the impacts of neoadjuvant HT on hormonal- and sexual-related quality of life (QOL) among patients who underwent robot-assisted RP (RARP).

Materials and Methods

Participants comprised 470 patients divided into a non-neoadjuvant HT group (n = 408) and a neoadjuvant HT group (n = 62). Hormonal- and sexual-related QOL were measured using the Expanded Prostate Cancer Index Composite (EPIC) questionnaire.

Results

Hormonal summary scores at 6 and 9 months, function scores before and 3, 6, and 9 months and bother score at 6 months after RARP were significantly lower in the neoadjuvant HT group than in the non-neoadjuvant HT group. Sexual function scores were decreased in the neoadjuvant HT group compared to the non-neoadjuvant HT group before and 6 months after RARP. In the neoadjuvant HT group, sexual function at 3 months after RARP was significantly worse in patients with >5 months of neoadjuvant HT than in patients with ≤5 months of neoadjuvant HT. Conversely, sexual bother at 3 months after RARP was significantly worse in patients with ≤5 months of neoadjuvant HT than in patients with >5 months of neoadjuvant HT.

Conclusion

Vintage neoadjuvant HT prior to RARP should not be recommended due to not only oncological outcomes, but also the impacts on postoperative hormonal- and sexual-related QOL.
