Radical prostatectomy (RP) is the primary and standard treatment for localized prostate cancer. As in many surgical procedures, RP can now be accomplished through minimally invasive methods. RP in a patient with a pre-existing 3-piece inflatable penile prosthesis (IPP) is an exceptional condition and involves coping with many difficulties. In this case report, we aimed to present a patient with pre-existing 3-piece IPP for whom we successfully performed robotic perineal RP (r-PRP)., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Introduction and Objective: Theaim of this study was to determine the effect formedby pelvic diameters preoperatively measured throughmultiparametric magnetic resonance imaging (mp-MRI) and different surgical positions on anesthesiaparameters used during perineal robot-assisted radicalprostatectomy (p-RARP). MATERIALS AND METHODS: Six different pelvimetricdimensions were determined preoperatively.Respiratory and hemodynamic variables of the patientswere measured separately and repeatedly in thesupine position, exaggerated lithotomy position at thebeginning of the 15° Trendelenburg position and the60th minute of insufflation. RESULTS: There was a significant increase in thepartial pressure of oxygen (PaO2) in the exaggeratedlithotomy position compared to the supine position.There was no significant change in the partial pressureof carbon dioxide (PCO2) in the exaggerated lithotomyposition compared to the supine position. In the 60thminute of insufflation, there was a significant increasein the PCO2 compared to the supine and exaggerated lithotomy positions. There was no statistically significantchange in the end-tidal carbon dioxide tension(EtCO2), with surgical position or insufflation time. Asignificant negative correlation was observed betweenthe distance of the ischial spines (ISD) and PCO2 change,and a significant positive correlation was observedbetween the angle of the symphysis pubis-seminalvesicles (ASS) and PCO2 change. A significant positivecorrelation was observed between the ASS value andEtCO2 change between the 60th minute of insufflationand exaggerated lithotomy position. CONCLUSION: In our study, the effect caused by differingpelvimetric diameters, surgical positions, andduration of anesthesia during p-RARP on anesthesiaparameters were shown.

Objective: Minimally invasive techniques are used increasingly by virtue of advancements in technology. Surgery for prostate cancer, which has high morbidity, is performed with an increasing momentum based on the successful oncological and functional outcomes as well as cosmetic aspects., Materials and Methods: 62 patients underwent robot-assisted perineal radical prostatectomy (R-PRP) surgery at our clinic between November 2016 and August 2017. Six pelvimetric dimensions were defined and measured by performing multiparametric magnetic resonance imaging (mpMRI) prior to operation in all patients. In light of these data, we aimed to investigate the effect of pelvimetric measurements on surgery duration and surgical margin positivity., Results: By using this technique in pelvic area, we observed that measurements only representing surgical site and excluding other pelvic organs had a significant effect on surgery duration, and pelvic dimensions had no significant effect on surgical margin positivity., Conclusion: In R-PRP technique, peroperative findings and oncological outcomes can vary depending on several variable factors, but although usually not taken into account, pelvimetric measurements can also affect these outcomes. However, there is a need for randomised controlled trials to be conducted with more patients., Competing Interests: None declared., (Copyright® by the International Brazilian Journal of Urology.)
