High Submuscular IPP Reservoir Placement: The "Five-Step" Technique.

Background: High submuscular (HSM) placement of inflatable penile prosthesis (IPP) reservoirs is a promising new FDA approved alternative to traditional space of Retzius reservoir placement. In 2011, we began placing all reservoirs in a HSM position at our tertiary center. In 2014, we proposed a refined, "Five-Step" HSM reservoir placement technique (FST) to prevent deep pelvic complications.
Objectives: To describe our HSM technique and report on our extended experience.
Material: Our refined FST was developed to optimize outcomes and includes the following steps: (1) Position and Access; (2) Develop Lower HSM Pocket; (3) Develop Upper HSM Pocket; (4) Reservoir Delivery (Fill and Fine-Tune); (5) Confirm and Connect. Data was retrospectively collected on patients undergoing reservoir placement by FST between January 2014 and June 2019. A survey analyzing subjective outcomes and patient satisfaction was performed among 100 randomly selected patients.
Results: We placed 297 consecutive HSM IPP reservoirs via FST during this time period. Three patients (1.0%) required surgical revision (all for herniation). No deep pelvic (vascular, bladder, bowel) complications were reported. Of the 100 patients that were randomly surveyed, 86% of patients reported no palpability of the reservoir, and 95% of patients reported satisfaction with the procedure and would recommend the procedure to a friend.
Conclusion: The FST for HSM reservoir placement is a simple and safe procedure with good outcomes and excellent patient satisfaction. This technique appears to effectively eliminate the risks of deep pelvic complications.
