Introduction:
Multiparametric magnetic resonance imaging (mpMRI) has enhanced the characterisation of prostate cancer (PCa) and its surgical management through robot-assisted radical prostatectomy (RARP). This study analyses the correlation between preoperative mpMRI findings and postoperative clinical outcomes.
Materials And Methods:
A retrospective analysis of a prospectively maintained multicentre database was conducted, including 1,136 patients who underwent RARP between 2011 and 2022 at two university hospitals. Patients were grouped according to postoperative PSA levels into success (SG) and recurrence (RG) groups. Clinical, imaging, and pathological variables were analysed.
Results:
The recurrence rate was 13.6%. RG patients had higher preoperative PSA levels, more T3-stage tumours on mpMRI, more positive surgical margins, and more postoperative complications. Urinary incontinence was significantly more common in RG (49.35% vs. 7.94%). While mpMRI had limited accuracy in predicting tumour extension, it contributed to surgical planning. Multivariable regression identified significant predictors of postoperative success.
Conclusion:
mpMRI is useful for patient selection and surgical planning in PCa, though its predictive accuracy still requires optimization.
