1. Penile prosthesis implant in the special populations: Diabetics, neurogenic conditions, fibrotic cases, concurrent urinary continence surgery, and salvage implants
Asian Journal of Andrology 2020;22(1):39-44
Penile prosthesis implant (PPI) remains an effective and safe treatment option for men with erectile dysfunction (ED). However, PPI surgery can be associated with a higher risk of complications in certain populations. This article provides a critical review of relevant publications pertaining to PPI in men with diabetes, significant corporal fibrosis, spinal cord injury, concurrent continence surgery, and complex salvage cases. The discussion of each category of special populations includes a brief review of the surgical challenges and a practical action-based set of recommendations. While specific patient populations posed considerable challenges in PPI surgery, strict pre- and postoperative management coupled with safe surgical practice is a prerequisite to achieving excellent clinical outcomes and high patient satisfaction rate.
2. Artificial urinary sphincter surgery in the special populations: Neurological, revision, concurrent penile prosthesis and female stress urinary incontinence groups
Asian Journal of Andrology 2020;22(1):45-50
The artificial urinary sphincter (AUS) remains the standard of care in men with severe stress urinary incontinence (SUI) following prostate surgery and radiation. While the current AUS provides an effective, safe, and durable treatment option, it is not without its limitations and complications, especially with regard to its utility in some 'high-risk' populations. This article provides a critical review of relevant publications pertaining to AUS surgery in specific high-risk groups such as men with spinal cord injury, revision cases, concurrent penile prosthesis implant, and female SUI. The discussion of each category includes a brief review of surgical challenge and a practical action-based set of recommendations. Our increased understandings of the pathophysiology of various SUI cases coupled with effective therapeutic strategies to enhance AUS surgery continue to improve clinical outcomes of many patients with SUI.

5.Penile Glans Necrosis Following Prostatic Artery Embolization for Benign Prostatic Hyperplasia: Case Series and Review of Current Literature
The World Journal of Men's Health 2023;41(2):396-402
Purpose:
To report a case series of 6 patients with penile glans necrosis (PGN) following prostatic artery embolization (PAE) and review the current literature relating to PAE and PGN, including the emerging role of hyperbaric oxygen therapy (HBOT) for PGN.
Materials and Methods:
All patients have failed medical BPH therapy and chose to undergo PAE over other minimally invasive BPH surgery. Patient demographics, preoperative and postoperative validated questionnaires such as the International Prostate Symptom Severity (IPSS) and International Index of Erectile Function (IIEF) scores, treatment-related adverse events (TRAE) and subsequent treatment for PGN were reviewed. All patients were follow-up with a minimum of 12 months post-PAE.
Results:
Between January 2018 and June 2020, six males with a mean age of 52.3 years (44–66 y) received PAE for BPH therapy. An immediate postoperative PGN was recognised in 4 out of 6 patients with the mean penile glans pain score of 3 and 4 patients reported altered penile glans sensitivity. Comparing the mean (and median) IPSS and IIEF-5 scores were 16.5 (16) and 21.3 (21) pre-PAE, there was improvements in IPSS and IIEF-5 scores at 12.0 (12) and 18.0 (18) at 12 months review. All patients reported normal penile glans sensitivity and only 1 patient reported an on-going penile glans pain (score 2). Four patients received HBOT while 2 patients elected for conservative care. All patients reported worse erectile function scores despite complete resolution of PGN.
Conclusions
PGN is a rare but serious complication of PAE with ensuing erectile dysfunction. HBOT appears to expedite the recovery process in men with PGN related to PAE with better erection scores compared to conservative measure.
6.Peyronie's disease and low intensity shock wave therapy: Clinical outcomes and patient satisfaction rate in an open-label single arm prospective study in Australian men.
Korean Journal of Urology 2015;56(11):775-780
PURPOSE: To evaluate the efficacy, safety and patient satisfaction outcomes following low intensity extracorporeal shock wave therapy (LiESWT) in men with Peyronie's disease (PD) using a standardised protocol. MATERIALS AND METHODS: In this open-label single arm prospective study, patients with PD were enrolled following informed consent. Patient demographics, change in penile curvature and plaque hardness, International Index of Erectile Function (IIEF)-5 score, and overall satisfaction score (on a 5-point scale) were recorded. Treatment template consists of 3000 shock waves to the Peyronie's plaque over 20 minutes, twice weekly for 6 weeks. RESULTS: The majority of patients have PD history longer than 6 months (mean, 12.8 months; range, 6-28 months). Two thirds of patients have received and failed oral medical therapy. There were improvements in penile curvature (more than 15 degrees in 33% of men), plaque hardness (60% of men) and penile pain (4 out of 6 men) following LiESWT. There was a moderate improvement in IIEF-5 score (>5 points reported in 20% of men). No complication was reported and the majority of patients were satisfied (rated 4 out of 5; 70% of men) and would recommend this therapy to others. CONCLUSIONS: In a carefully selected group of men with PD, LiESWT appears to be safe, has moderate efficacy and is associated with high patient satisfaction rate in the short term.

The World Journal of Men's Health 2023;41(1):94-100
Purpose:
To evaluate the clinical efficacy and patient satisfaction rates of low-intensity extracorporeal shockwave therapy LIESWT) in men with vasculogenic erectile dysfunction (ED) using Duolith SD1 machine.
Materials and Methods:
This prospective, randomized, double-blinded clinical trial included 60 men who were randomly assigned to LIESWT (n=30, active group) or placebo (n=30) over 6 weeks. Patient demographics, change in International Index of Erectile Function (IIEF)-5, Erection Hardness Score (EHS) and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores, and an overall satisfaction score (on a 5-point scale), were recorded. All patients were reviewed at 1, 3, and 6 months after completion of therapy.
Results:
There were 21 (70%) patients in the LIESWT group and 3 (10%) patients in the placebo group who had a 5-point or greater increase in IIEF-5 score (p=0.018). At 6-month study period, the mean IIEF-5 score was 18.8 (standard deviation [SD], 3.8) in the LIESWT group versus 14.8 (SD, 3.6) in the placebo group, difference in means between groups was 4.0 (95% confidence interval, 2.1–5.9; p<0.001). The EHS scores were higher in the LIESWT group with a mean of greater than 1.2 across the 1, 3, and 6 months compared to the placebo group (p<0.05). All patients completed the treatment study and there was no adverse event reported in terms of penile pain, bruising or deformity. There was a positive correlation between men who reported improvement in EF and treatment satisfaction level with LiESWT (p=0.008).
Conclusions
LIESWT improves erectile function in the short-term especially in men with mild to moderate ED, and those without a cardiometabolic disease.

The efficacy of intravesical onabotulinumtoxinA (BTXA) in the treatment of overactive bladder (OAB) has been well documented. The use of BTXA injection in orthotopic neobladders is yet to be studied. We present 4 cases of patients injected with intravesical BTXA for overactive orthotopic ileal neobladder. We recorded patient demographics, presenting and follow-up symptoms, urodynamic profiles, and Patient Global Impression of Improvement (PGI-I) scores. The 4 patients reported varying degrees of subjective improvements in the symptoms, including urgency, urge incontinence, and pad usage. Mean follow-up duration was 8.3 months (range, 5-14 months). Average PGI-I score was 3 ("a little better") (range, 2-4). To our knowledge, the current study is the first case series examining BTXA injection for orthotopic neobladder overactivity. BTXA injection yielded varying degrees of objective and subjective improvements, without significant complications. Intravesical BTXA injection is feasible and may be considered as a potential treatment alternative for OAB in orthotopic neobladders, although further study is warranted.

PURPOSE: To report on lessons learnt in the management of primary invasive penile cancer in a major tertiary hospital in Australia. MATERIALS AND METHODS: Medical records for all patients who underwent surgery for primary invasive penile cancer between January 2000 and January 2011 were obtained. Patient demographics, clinical status of inguinal node, cancer stage and clinical outcomes were reviewed. All patients were followed up for a minimum of 48 months postoperative unless patient deceased within the first 48 months from the time of penile cancer surgery. RESULTS: Over the 11-year period, a total of 23 cases of invasive penile cancer were identified. Partial penectomy was the most common form of organ preserving surgery and the majority of patients have pT1b disease. Of the 9 patients with clinically palpable inguinal nodes, 7 patients were diagnosed with pN3 disease following inguinal lymphadenectomy. The Kaplan-Meier cancer-specific survival at 72 months showed decreasing survival based on tumour stage (83% in pT1, 79% in pT2, and 64% in pT3 disease) and nodal disease (100% in node negative, 50% in superficial inguinal lymphadenopathy, and 38% in patients with deep inguinal and/or pelvic lymphadenopathy) (p=0.082). The Kaplan-Meier cancer-specific survival revealed statistically significant difference in survival outcome in patients with local recurrence vs. systemic metastasis disease (33% vs. 17%, p=0.008). CONCLUSIONS: The presence of high risk features such as tumour stage, lymph node involvement and distant metastasis carries a significant higher risk of death and tumour recurrence in patients with penile cancer and inguinal lymph node metastasis.
