(24) INTRODUCING THE PENILE IMPLANT INTRAOPERATIVE MEASUREMENTS PLANNING (PIIMP) CHART: A CHART USED FOR INTRAOPERATIVELY DOCUMENTING PENILE DIMENSIONS DURING PENILE PROSTHESIS IMPLANTATION PROCEDURES.

Abstract Objectives In this study, the Penile Implant Intraoperative Measurements Planning (PIIMP) chart was used to find out whether inflatable penile implants were more likely to procure a longer penile length in comparison to malleable implants. Methods 193 men undergoing penile prosthesis implantation were included in the study. 153 had malleable implants, while 40 had three piece inflatable implants. Penile measurements were recorded intraoperatively using the PIIMP chart. Penile length and circumference were taken in both a stretched and unstretched state. Measurements were repeated after pharmacologically induced tumescence by means of a PGE1 intracorporal injection (ICI). Postoperative penile dimensions were re-taken after implantation and documented together with cylinder dimensions. Results In malleable penile implants, postoperative penile length ranged between pre-operative pre-ICI stretched length and post-ICI stretched length 71.4% of times (n = 110/153). It fell below pre-operative pre-ICI stretched length in 26.2% of cases (n=40/153) and reached beyond pre-operative post-ICI stretched length in 1.96% of cases (n=3/153). In inflatable penile implants postoperative penile length ranged between pre-operative pre-ICI stretched length and post-ICI stretched length 60% of times (n= 24/40). It fell below pre-operative pre-ICI stretched length in 27.5% of cases ( n = 11/40) and reached beyond pre-operative post-ICI stretched length in 12.5% of cases (n = 5/40). Using Fisher's exact test, it was found that postoperative penile length was 6.37 times more likely to rise above preoperative post-ICI stretched length in inflatable penile implants compared to malleable implant cases (12.5% vs 1.96%) (P value=0.0105) Conclusions The PIIMP Chart demonstrated that aggressive penile sizing was more attainable with inflatable rather than malleable implants. The chart may be used as an intraoperative measurements guide for surgeons as well as serving as an objective postoperative counseling tool for patients, where their pre and postoperative penile dimensions would be documented and easily comparable.
