Penthrox is a portable handheld inhaler that delivers a low dose of methoxyflurane - an anesthetic with analgesic effects, rapid onset of action, and a favorable side-effect profile. It has been widely used for acute pain management in Australia for the past 40 years. Currently, it is approved for use in over 55 countries, including Canada. Prospective randomized studies highlight Penthrox analgesic effectiveness and safety profile for emergency, prehospital and outpatient settings. In addition, the use of multimodal analgesia, specifically Penthrox, can play an important role in the analgesic management of urological procedures, such as prostatic biopsies and office-based minimally invasive surgical therapies. Herein readers will familiarize themselves with Penthrox, significant studies, and technique used for outpatient urological procedures.

Distal hypospadias is a common congenital urology anomaly for which numerous corrective procedures have been described. Over the last 40 years, the gold-standard operative technique for distal hypospadias has switched from the meatal advancement and glanuloplasty (MAGPI) procedure to the tubularized incised plate (TIP) urethroplasty. A modification to the MAGPI procedure, first described 30 years ago, is the M inverted V (MIV) glansplasty, which improved upon the MAGPI procedure to reduce instances of meatal retraction. The MIV glansplasty is unique compared to many commonly used procedures as it does not require a formal urethroplasty or incorporation of a dartos flap, and it does not always necessitate as extensive mobilization of the glans wings. We describe our updated technique and outcomes of the MIV glansplasty and delineate situations where the MIV is best employed.

Proximal positioning of the penile prosthesis cylinder is performed during inflatable penile prosthesis surgery. We describe a technique to secure a prosthetic cylinder during inflatable penile prosthesis implantation. Urologists performing prosthetic surgeries employ a variety of surgical techniques to achieve successful outcomes. A surgical technique that secures the prosthetic device may ultimately mitigate cylinder migration and erosion. This is a simple, cost-effective technique that can be readily incorporated into conventional corporotomy closure procedures. It proves to be a feasible technique for both running and interrupted corporotomy closures. The “pulley stitch” offers an adjunctive technique for prosthesis cylinder positioning and may also help prevent migration of prosthetic devices, and it can be incorporated with corporotomy closure.

Aquablation has been well-studied in prostates sizes up to 150 mL. Recently, American Urological Association guidelines distinguish surgical interventions for men with large prostates (80 mL-150 mL) and now very large prostates (> 150 mL). Readers will gain an understanding of how to use Aquablation in the very large prostate size category.

3D printing has been growing in many surgical fields including Urology. The primary use has been to print kidneys with tumors to better understand anatomy and to assist with surgical planning and education. Previous studies that utilized 3D printing of kidneys for partial nephrectomies have been limited by the cost and complexity of model creation, rendering them highly impractical to be used on a routine basis. Using a simpler and more cost-effective design and materials allow the 3D kidney models to be used in a wider range and number of patients. We describe our streamlined process to create 3D kidney models costing $30 on average and we believe this process can be repeated by others.
