Post malleable Penile Prosthesis Satisfaction in elderly patients: Serial assessments

Surgical Outcomes and Patient Satisfaction With the Low-Cost, Semi-Rigid Shah Penile Prosthesis: A boon to the Developing Countries

Introduction

In developing countries most patients with refractory erectile dysfunction cannot afford a penile prosthesis (PP) due to its cost and non-coverage by insurance companies.

Aim

To assess the patient satisfaction outcomes with a novel, low-cost, semi-rigid PP.

Methods

52 patients who had received the Shah semi-rigid PP between January 2013 and December 2018 were included in this bidirectional study. Patient demographics including age, etiology, body mass index, length of PP received and post-operative complications were recorded. Patient satisfaction with the PP was evaluated using the modified Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) Questionnaire.

Main outcome measures

The primary outcome measures were overall satisfaction, total EDITS and mean EDITS score. The secondary outcome measures were residual penile tumescence, ease of concealment and post-operative complications.

Results

The mean age of the patients was 38.79 years (25–68). Overall satisfaction (EDITS Q-1) of 4 (0–4) was reported by 84.62% (44/52) of patients. There was no significant difference (P > .7) in the total EDITS and overall satisfaction based on various etiological factors. The mean EDITS scores (0–100) were 95.67 ± 10.76, 95.53 ± 8.46 and 91.72 ± 22.42 in 52 patients with BMI <25, 25–29.9 and >30 kg/m2 respectively. During sexual arousal after PP implantation, 26 (50%), 17 (32.7%) and 9 (17.3%) patients noted “good”, “some” or “no” residual penile tumescence respectively. 47 (90.4%), 4 (7.7%) and 1 (1.9%) patients reported “good”, “fair” and “poor” concealment respectively. In the prospective group, major and minor post-operative complications were seen in 10.7% (3/28) and 21.4% (6/28) of patients respectively.

Conclusion

The semi-rigid Shah PP is a safe, effective and affordable option to treat patients with refractory ED. The ability to remove 1 or both sleeves in the Shah PP helps achieve a good fit with a small inventory. Krishnappa P, Tripathi A, Shah R.

Update on Intraoperative Cultures, Biofilms, and Modifiable Factors During Revision of Clinically Non-Infected Penile Implants

INTRODUCTION

Penile implants have a limited lifespan, and as the population using inflatable penile prostheses ages, revision surgery has become increasingly common. Devices are frequently cultured during non-infectious revision surgeries, providing a burgeoning of evidence of positive cultures without clinical infection. However, the clinical significance of these cultures remains unclear.

OBJECTIVES

We aim to review the current literature on culture results from revision surgery for clinically non-infected devices and summarize the available data to formulate a synopsis of clinically significant organisms and their significance and modifiable approaches to prosthesis surgery.

METHODS

A literature review was performed on 1 March, 2020 in PubMed and Google Scholar. Search terms centered on penile prosthesis revision surgery, cultures, and infection. Titles and abstracts were reviewed for topical relevance with emphasis placed on literature from the last 20 years. Most publications comprised small case series aside from a single meta-analysis.

RESULTS

Since 1995, seven series have been published examining culture positivity at the time of revision surgery for clinically non-infected devices. Isolated organisms are most commonly from the Staphylococcus genus with Staphylococcus epidermidis being the most frequently isolated organism on clinically non-infected devices. Reported culture positivity rates at the time of revision range between 9.8% and 80%.

CONCLUSION

Current literature pertaining to the clinical significance of culture positivity at the time of revision surgery for clinically non-infected penile prostheses is lacking; however, multiple series do report high rates of culture positivity. This does appear to confer a higher rate of subsequent infection and a lower revision-free survival. Staphylococcus epidermidis is the most commonly isolated organism followed by other members of the Staphylococcus genus. Further studies are needed to determine the impact of modifiable variables or techniques on asymptomatic culture positivity and the ideal technologies for biofilm prevention.
