Comparison of satisfaction with penile prosthesis implantation in patients with prostate cancer radiation therapy versus radical prostatectomy.

Background: Penile prosthesis surgery (PPS) is a commonly used treatment for erectile dysfunction (ED), either as first-line therapy or in cases refractory to other treatment options. In patients with a urologic malignancy such as prostate cancer, surgical interventions like radical prostatectomy (RP) as well as non-surgical treatments such as radiation therapy can all induce ED. PPS as a treatment for ED has high satisfaction rates in the general population. Our aim was to compare sexual satisfaction in patients with prosthesis implantation for ED following RP versus ED following radiation therapy for prostate cancer. Methods: A retrospective chart review from our institutional database was conducted to identify patients who underwent PPS at our institution from 2011 to 2021. Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire data at least 6 months from implant operative date available was required for inclusion. Eligible patients were placed in one of two groups depending on etiology of ED-following RP or prostate cancer radiation therapy. To prevent crossover confounding; patients with history of pelvic radiation were excluded from the RP group and patients with history of RP were excluded from the radiation group. Data were obtained from 51 patients in the RP group and 32 patients in the radiation therapy group. Mean EDITS scores and additional survey questions were compared between the radiation and RP groups. Results: There was a significant difference in mean survey responses for 8 of the 11 questions in the EDITS questionnaire between the RP group and the radiation group. Additional survey questions administered also found RP patients reported significantly higher rate of satisfaction with size of penis post-operatively versus the radiation group. Conclusions: These preliminary findings, while requiring large-scale follow-up, suggest that there is greater sexual satisfaction and penile prosthesis device satisfaction in patients undergoing IPP placement following RP versus radiation therapy for prostate cancer. Use of validated questionnaires should continue to be utilized in quantifying device and sexual satisfaction following PPS.

Does knowing pre-operative penile length influence patient satisfaction post penile prosthesis implantation?

Patients who undergo penile prosthesis implantation as treatment for erectile dysfunction commonly complain of penile shortening after implantation. We conducted a study to determine whether knowledge of pre-operative stretched penile length measurement influences patient satisfaction. This prospective study consisted of 149 patients undergoing inflatable penile prosthesis (IPP) implantation from August 2017 to December 2019. Study group participants underwent pre-operative stretched penile length measurement in clinic while the control group did not. Six months post-operatively, patients completed a modified 14-item Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire to assess overall satisfaction and penile length satisfaction. A total of 102 patients were eligible for final analysis (49 in study group, 53 in control). Mean scores for overall treatment satisfaction were 3.57 and 3.53 (scale from 0 to 4) in the study versus control group, respectively (p = 0.483). Mean scores for satisfaction with penile length were 4.08 and 4.11 (scale from 1 to 5) in the study vs. control group (p = 0.645). The study suggests that knowledge of pre-operative stretched penile length does not influence post-operative satisfaction after penile prosthesis implantation. Therefore, performing pre-operative measurements in clinic solely for informing the patient may be unnecessary. Current interventions aimed at conserving penile length may be effective at maintaining satisfaction with penile length.Trial Registration- This trial is registered and approved by the IRB committee at our institution, ID: HSC-MS-19-0320.

Comparison of Satisfaction With Penile Prosthesis Implantation in Patients With Radical Prostatectomy or Radical Cystoprostatectomy to the General Population.

INTRODUCTION: Penile prosthesis implantation is a widely used treatment option for erectile dysfunction. Data is limited with regard to patient satisfaction with a penile prosthesis following radical prostatectomy/cystoprostatectomy vs patients with erectile dysfunction of other etiologies. AIM: To examine patient satisfaction with penile prosthesis implantation and determine if a difference in satisfaction exists in post-prostatectomy/cystoprostatectomy patients vs patients with erectile dysfunction of other etiologies. We hypothesize that etiology does not affect satisfaction. METHODS: A total of 164 patients underwent penile prosthesis implantation at our institution between August 2017 and December 2019, with 102 patients completing a validated 14 item questionnaire, Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), at 6 months postoperation. Demographics, surgical characteristics, and erectile dysfunction etiology were recorded. Patients were assigned to one of 2 groups: postprostatectomy/postcystoprostatectomy erectile dysfunction or other etiologies. The study group was further analyzed between radical prostatectomy or radical cystoprostatectomy. MAIN OUTCOME MEASURES: Satisfaction based on key EDITS questions with postradical prostatectomy/cystoprostatectomy vs patients with erectile dysfunction of other etiologies. RESULTS: Responses to 3 questions were analyzed: overall satisfaction, expectations met in the past 4 weeks, and confidence in the ability to participate in sexual activity. Chi-square analysis was performed to determine the difference in responses. No difference was seen in overall satisfaction (P = .96), expectations (P = .78), or confidence (P = .78) between groups. On subgroup analysis, there was no difference in reported overall satisfaction (P = .47) or confidence (P = .080) between postprostatectomy and postcystoprostatectomy patients. Postprostatectomy and postcystoprostatectomy patients differed in whether the penile prosthesis implantation met expectations (P = .033). Postprostatectomy patients reported a mean score of 3.5/4 compared to postcystoprostatectomy patients, who reported a mean of 3.0/4. CONCLUSIONS: Our analysis suggests that key erectile function scores are not significantly different between postprostatectomy/postcystoprostatectomy patients compared to other etiologies. The difference in measures between postprostatectomy and postcystoprostatectomy patients is not significant or of unclear significance.

Expanding the Limits-Improving Penile Length With Inflatable Penile Prosthesis Implantation: A Review.

INTRODUCTION: Erectile dysfunction is a multifactorial disorder that increases in prevalence as men age. When medical therapy fails or when men are unwilling to try it, surgical intervention becomes the urologist's next best tool. However, the loss of penile length is of great concern to many patients, and there have been a myriad of ways to try to combat this fear from both patients and the surgeons themselves. In this review, we evaluate the current literature of these various approaches to improve penile length in penile prosthesis surgery. OBJECTIVES: To review novel techniques in penile prosthesis implantation surgery. METHODS: A literature search using PubMed was conducted to identify relevant peer-reviewed studies to penile prosthesis surgery. Search terms included penile prosthesis, penile shortening, sliding technique, Peyronie's Disease, erectile dysfunction, nondegloving, penile length, and Multiple Slice Technique. RESULTS: Novel techniques included preoperative techniques such as use of vacuum-assisted erection device, intraoperative techniques of aggressive dilatation and maximal sizing, ventral phalloplasty and/or scrotoplasty, suprapubic fat pad excision, relaxing tunica albuginea incisions, a sliding or slicing technique, or the postoperative use of penile rehabilitation. In addition, recognizing recall bias or inconsistencies in measurement techniques is important when evaluating men with possible penile shortening after penile prosthesis surgery. CONCLUSIONS: Advancements in surgical techniques and managing patient expectations can be crucial in the success of penile prosthesis surgery.

Initial Results of First In Vivo Imaging of Bladder Lesions Using a High-Resolution Confocal Microendoscope.

Purpose: Conventional cystoscopy plays an important role in detection of bladder cancer; however, it is difficult to differentiate benign and neoplastic lesions based on cystoscopic appearance alone. Advanced microscopic modalities, such as confocal laser endomicroscopy and optical coherence tomography, have been shown to provide critical histopathologic information to help identify neoplastic bladder lesions in real time, but their availability and clinical adoption are limited due to a high cost. In this study, we present the first use of a novel and low-cost ($ <5000) confocal high-resolution microendoscope (confocal HRME) for in vivo imaging of bladder lesions. Materials and Methods: In a cohort of 15 patients undergoing white light cystoscopy as part of their standard of care, high-resolution images of proflavine-stained bladder lesions were acquired in vivo using the confocal HRME. Based on these images, we evaluated the ability of the confocal HRME to visualize uroepithelium with subcellular resolution and high contrast. Furthermore, we analyzed the cellular architecture and staining patterns of benign and neoplastic bladder lesions in confocal HRME images and compared results to that of standard cystoscopy and histopathology. Results:In vivo imaging in the pilot study demonstrates that the confocal HRME resolved subcellular structures of bladder uroepithelium with high contrast. In a wide range of clinical conditions from normal bladder wall to benign and neoplastic lesions, confocal HRME images revealed important diagnostic features that correlated to histopathology. Conclusions: The confocal HRME provides an affordable, portable, and easy-to-use tool to allow real-time and high-contrast subcellular characterization of bladder lesions, well suited for bladder cancer detection in community and resource-constrained settings.

Orgasm-associated urinary incontinence (climacturia) following radical prostatectomy: a review of pathophysiology and current treatment options.

Orgasm-associated urinary incontinence, or climacturia, is a common side effect after radical prostatectomy (RP) that is gaining more attention due to the distress it causes to patients. A range of treatment options have been reported in the literature and are outlined in this review. The goal of our study is to review the pathophysiology and current management options for climacturia following RP. A PubMed search was used to review the current literature relating to the pathophysiology and the treatment of postprostatectomy climacturia. We reviewed the currently available treatment options and their success rates for climacturia. Several techniques were found to subjectively help improve the amount and bother of patients' climacturia. These include pelvic floor muscle training (PFMT), penile variable tension loop, soft silicone occlusion loop, artificial urethral sphincter, male urethral sling, and the Mini-Jupette graft. Success rates ranged from 48% to 100% depending on the modality used. For patients with erectile dysfunction and climacturia, the Mini-Jupette graft could be a valuable option. Given the lack of validated measurement tools and management options, climacturia has become a challenge for urologists. Albeit a condition that has not garnered much attention, there are several management options from conservative to invasive treatments that have shown a hopeful promise for the treatment of climacturia. These options should be discussed with patients to determine the best treatment for each individual. More clinical trials are needed to assess the efficacy and impact of the different treatment options before a definitive recommendation regarding management can be made.
